Lubricants are primarily composed of base oils and additives, with the base oil defining the lubricant's fundamental properties. Base oils are generally categorized into two types: mineral oils and synthetic oils. They differ significantly in terms of raw materials, production processes, and performance characteristics. This article provides a systematic comparison to help you select the most suitable lubricant for your needs. 1. Mineral Oil: Cost-Effective and Widely Applicable Raw Materials and Production Process​ Mineral oil is derived from crude oil through distillation, solvent refining, dewaxing, and hydrotreating. Traditional methods involve solvent refining and clay treatment, while modern production commonly employs hydroprocessing to enhance performance. Performance Characteristics​ Varied by Category: Group I oils offer moderate viscosity-temperature performance and limited oxidation stability. Group II/III oils, improved through hydroprocessing, exhibit better viscosity index and oxidation resistance, with Group III oils approaching the performance of synthetic oils. Advantages: Lower cost (typically 1/3 to 1/2 that of synthetic oils); good compatibility with most seal materials; mature production processes and stable supply chains. Limitations: Less suitable for severe operating conditions (high temperature, high pressure, etc.); shorter service life and more frequent oil changes; slow biodegradation, posing higher environmental risks in case of leakage. 2. Synthetic ester: High Performance and Extended Service Life Raw Materials and Production Process​ Synthetic oils are chemically synthesized from small molecules such as ethylene and propylene, derived from natural gas or petroleum. Main categories include: PAO (Group IV): Polyalphaolefin, the most common synthetic base oil. Esters, Polyglycols, etc. (Group V): Produced through esterification or ring-opening polymerization. Performance Characteristics​ Excellent Oxidation and Thermal Stability: Stable molecular structure resists oxidation and breakdown. Superior Viscosity-Temperature Performance: High viscosity index ensures effective lubrication at high temperatures and good fluidity at low temperatures. Improved Friction Properties: Strong oil film formation helps reduce energy consumption. Advantages: Suitable for extreme operating conditions; extended service life (drain intervals can be 2–3 times longer than mineral oils); lower maintenance costs over time. Limitations: Higher cost (typically 2–3 times that of mineral oils); potential compatibility issues with some seal materials; complex production processes and higher technical barriers. 3. How to Choose the Right Base Oil Choose Mineral Oil If: Operating conditions are mild, cost is a primary concern, and maintenance or oil changes are easily managed. Choose Synthetic Oil If: Equipment operates under high or low temperatures, heavy loads, or extreme conditions, or if extended oil drain intervals and reduced maintenance downtime are desired. Choosing the correct lubricant base oil not only ensures smooth equipment operation but also improves energy efficiency and reduces maintenance costs. Whether selecting mineral oil for standard applications or synthetic oil for demanding environments, matching the lubricant to the actual need ensures both economy and performance.

With the rapid development of modern industry and the increasing prominence of environmental issues, there are growing requirements for lubricants in terms of performance, operational reliability, service life, biodegradability, and low or non-toxicity. Traditional mineral-based lubricating oils can no longer meet these stringent demands. Synthetic esters exhibit the best overall performance among all base oils. The most significant characteristic of ester oils is the presence of multiple ester bonds (-COOR) within the ester molecules. This structure imparts polarity to the molecules, providing ester oils with many superior performance and application characteristics compared to PAO (polyalphaolefins) and Group II or Group III hydrocracked base oils. Application Industries of Synthetic Ester Base Oils 1. Engine Oils: Primarily diesters and polyol esters; others include polyesters, monoesters, phthalate esters, and dimer acid esters. 2. Two-Stroke Oils: Generally utilize trimellitates, complex esters, dimer acid esters, and polyol esters. 3. Compressor Oils: Generally utilize diesters and polyol esters; additionally, PAG (polyalkylene glycol) polyether base oils can be used. 4. Aviation Lubricants: Generally utilize diesters and polyol esters. 5. Fire-Resistant Hydraulic Fluids: Typically utilize trimethylolpropane (TMP) oleate and pentaerythritol (PE) oleate. 6. High-Temperature Chain Oils: Generally utilize diesters and polyol esters; additionally, PAG polyether base oils can be used.

Polyalkylene Glycol (PAG)is a type of polymer synthesized from alkylene oxides, characterized by low toxicity, good water solubility, excellent surface activity, as well as adjustable viscosity and lubricating properties. Its applications in lubricants mainly include the following areas:   1. Industrial Lubricants PAG is commonly used as a base oil for gear oils and high-temperature chain oils. It offers a high viscosity index, good extreme pressure performance, and low carbon deposit tendency. Suitable for heavy-duty gear systems in equipment such as textile heat-setting machines and plastic calenders, it remains stable at high temperatures and demonstrates good compatibility with rubber seals.   2. Compressor and Refrigeration Oils Polyalkylene Glycol exhibits good miscibility with refrigerants such as R-134a and possesses clean-burning characteristics, helping to reduce sludge and carbon deposits. With excellent lubricity, chemical stability, and low-temperature fluidity, it is widely used in automotive air conditioning and industrial refrigeration systems.   3. Metalworking Fluids​ PAG can form an effective lubricating film on metal surfaces, providing outstanding lubrication and cooling effects. It exhibits reverse solubility—soluble in water at room temperature but precipitating and adhering to metal surfaces when in contact with high-temperature tools, thereby enhancing lubrication. It is often used in fully synthetic or semi-synthetic metalworking fluids.   Zhengzhou Chorus specializes in lubricant additives, with Polyalkylene Glycol (PAG) as one of our flagship products. For applications such as gear oils, compressor oils, and refrigeration oils, we provide customized solutions that deliver cleanliness, cooling, lubrication, and environmental performance.

ZDDP anti-wear additive, also known as Zinc Dialkyl Dithiophosphate, is a chemical substance widely used in lubricants and fuel additives. With its excellent anti-wear, anti-oxidation, and anti-corrosion properties, it plays a crucial role in the industrial and automotive sectors. The main components of ZDDP anti-wear additive are compounds of zinc and phosphorus. These compounds form a protective film in the lubricant, effectively reducing direct contact between metal parts, thereby reducing wear and extending equipment lifespan. ZDDP anti-wear additive reacts chemically with the metal surface through the active groups in its molecular structure, generating a stable chemisorbed film. This film can withstand high pressure and high temperature, and effectively resist oxidation and corrosion, protecting the metal surface from damage. In addition, ZDDP anti-wear additive can also work synergistically with other additives in the lubricant to further enhance the lubricant's performance. In terms of application scenarios, ZDDP anti-wear additive is widely used in various mechanical equipment requiring lubrication, such as automobile engines, industrial gearboxes, and compressors. In the automotive industry, it is added to engine oil to improve the wear resistance and corrosion resistance of the engine, reduce maintenance costs, and extend engine life. In the industrial field, ZDDP anti-wear additive is used in the lubrication systems of various heavy machinery and equipment to ensure stable operation even under harsh working conditions.   Regarding industry standards, the production and use of ZDDP anti-wear additive must comply with strict quality control and safety regulations. Different countries and regions may have specific regulations on its composition, content, and scope of use to ensure product safety and environmental protection. Therefore, when choosing ZDDP anti-wear additive, attention should be paid to whether it meets relevant industry standards and whether it has been certified by authoritative institutions.   Furthermore, with the increasing environmental awareness, low-phosphorus, low-zinc, or phosphorus-free and zinc-free environmentally friendly anti-wear additives have appeared on the market to meet the needs of applications with higher environmental requirements. These new anti-wear additives maintain their original performance while reducing environmental pollution, representing a future development trend.   When using ZDDP anti-wear additive, attention should also be paid to its dosage and replacement cycle. Excessive addition may lead to a decrease in lubricant performance and even damage to equipment; while excessively long replacement intervals may weaken the anti-wear effect and increase the risk of equipment wear. Therefore, it is recommended to determine the appropriate addition amount and replacement cycle based on the equipment manufacturer's recommendations and actual usage conditions. The recommended dosage of ZDDP anti-wear additive in lubricating oils is 0.5%-3.0% (by weight). For example, when used in industrial lubricants such as gear oil and hydraulic oil, this additive range ensures its anti-oxidation, anti-corrosion, and extreme pressure anti-wear performance. Precautions for using ZDDP anti-wear additive:   Control temperature: Avoid using at temperatures above 160℃, as high temperatures can cause ZDDP molecules to decompose, losing their anti-wear properties. Add according to dosage: Strictly follow the dosage specified in the instructions. Excessive amounts may cause chemical wear or affect lubricant performance. Regular oil changes: After adding the anti-wear additive, change the engine oil according to the vehicle manufacturer's recommended cycle to prevent the accumulation of impurities.   Supplementary notes on the use of ZDDP anti-wear additive: 4. Compatibility testing: It is recommended to perform compatibility testing with the base oil before use to avoid precipitation or stratification, especially when mixing with synthetic oils. 5. Storage conditions: Store in a sealed container in a cool, dry place (recommended temperature ≤30℃), and avoid contact with strong oxidizing agents to prevent inactivation. 6. Environmental disposal: Waste lubricating oil containing ZDDP must be disposed of according to hazardous waste standards, as its phosphorus content may affect the environment.

1. Corrosion: A high pH provides corrosion protection for ferrous metals. The closer the pH is to 14, the less ferrous metals rust. Non-ferrous metals are amphoteric, meaning that the potential for corrosion increases with increasing or decreasing pH from 7. Aluminum is not susceptible to corrosion at pH levels between 6.5 and 8.5. The exception is magnesium (Mg), which is not susceptible to corrosion at high pH values. The pH response of other materials, such as nickel (Ni), chromium (Cr), and cobalt (Co), is highly dependent on the specific alloy type.   2. Metal Solubility: The dissolution of metals into working fluids follows the same principles as corrosion (rust). Alkalinity strictly controls the amount of metal dissolved into the working fluid. While alkalinity is important, it must be tailored to the working fluid and its specific pH.   3. Emulsion Stability: For traditional emulsions, increasing the pH of the working fluid results in smaller emulsion particles. Lowering the pH increases the size of the emulsion particles, which can lead to delamination. Smaller emulsion particles provide improved wettability and reduce the amount of carryover. Large-particle emulsions can improve the lubrication performance of mechanical fluids, but they also increase daily carryover. Adjusting the pH of the machining fluid, depending on the presence of contaminants in the fluid tank, can alter the fluid's ability to resist contaminants or its emulsification capacity.   4. Dermatitis: The further the machining fluid's pH deviates from 7.0, the more likely it is to cause dermatitis. Generally, a pH <9.5 is recommended for machining fluids during operation. When skin is exposed to alkaline environments, the alkali in the fluid saponifies the oils on the skin's surface, causing dryness and even cracking.   5. Bacterial and fungal growth: Bacteria and fungi can grow at any pH and in any environment. When the pH of a metalworking fluid increases, bacterial growth slows. Therefore, increasing the pH can reduce bacterial growth. However, fungi in metalworking fluids grow faster in highly alkaline conditions.   6. Compatibility with machine tools: Extreme pH values, whether highly alkaline or acidic, can cause corrosion of machine tool components. Contact between dissimilar metals (aluminum or copper with steel or cast iron) can cause corrosion. At extreme pH values, elastomers (such as seals) lose their flexibility. Plastic windows can become brittle.   When using different types of metalworking fluids to process different metals, we recommend maintaining different pH values ​​in the fluid bath to ensure optimal performance, maximize bath life, ensure adequate tool lubrication, and achieve excellent surface roughness on the workpiece.

1. Essential Difference: Significant Difference in Additive Formula Zinc-containing (ashy) hydraulic fluid, as the name suggests, contains a zinc antiwear agent (zinc dialkyl dithiophosphate, or ZDDP) or use hydraulic oil additive package with zinc. A zinc content greater than 0.03% is considered high-zinc, while a content less than 0.03% is considered low-zinc. After combustion, zinc oxide ash remains, hence the name "ashy."   Ashless hydraulic oil contains no metal additives and uses a sulfur-phosphorus antiwear agent, can use ashless hydraulic oil additive package to blend. And leaving no metal oxide residue after combustion. It's particularly suitable for systems with silver components.   2. Selection Guide: Optimize the Oil for the Equipment 1) Choose a zinc-containing hydraulic fluid when the equipment has these characteristics: Heavy-duty applications such as construction machinery and mining equipment use traditional hydraulic pumps such as the YB-D25 vane pump and PF15 plunger pump. The system operates in a -10°C to 40°C temperature range. Limited budget and no silver components.   2) Choose ashless oil in the following situations: Precision CNC machine tools, servo valve control systems containing copper alloy or silver-plated components (such as certain valves); Working conditions with frequent water contact (such as marine hydraulic systems); Extended oil change intervals (for improved oxidation stability); Locations with strict environmental requirements

Both ASTM D3306 (a standard of the American Society for Testing and Materials) and BS 6580:1992 (a British standard) specify the performance of engine coolants (antifreeze). However, due to differences in their formulation backgrounds, applicable scenarios, and technical focuses, there are significant variations in scope of application, performance requirements, and testing methods. The following is a comparative analysis from core dimensions: I. Scope of Application and Product Positionin Dimension ASTM D3306 BS 6580:1992   Core Positioning   A comprehensive specification covering coolants for automotive and light-duty engines A specification focusing on the anti-corrosion performance of engine refrigerant concentrates       Coolant Types Explicitly includes ethylene glycol-based, propylene glycol-based, ethylene glycol-glycerin blended coolants, etc., and allows coolants made from recycled/reprocessed raw materials   Primarily targets traditional ethylene glycol-based concentrates; no clear mention of propylene glycol or recycled raw materials     Application Scenarios   Applicable to liquid-cooled internal combustion engines in automobiles, light trucks, etc., covering new coolants and maintenance coolants Applicable to various liquid-cooled internal combustion engines (including automotive and industrial engines), with an emphasis on the   initial performance of concentrates     Dilution Requirements Specifies that concentrates should be diluted at a volume ratio of 40%-70% for use, or high-concentration (≥50%) products can be used directly No clear dilution ratio; only emphasizes that concentrates must    meet performance requirements after dilution

Did you choose the right metalworking oil emulsifier? These 7 key points must be read! ‌   1. Emulsifier selection: from HLB value to the art of proportioning Core Influencing Factors: The structure and type of emulsifier are crucial to emulsion performance, having a greater impact than factors like emulsification method and temperature. For example, surfactants with an HLB value (hydrophile-lipophile balance) of 3-6 are suitable for W/O emulsions, while those with an HLB value of 8-18 are suitable for O/W emulsions. Choosing the wrong type can lead to emulsion separation or failure.   Golden rules for mixing emulsifiers: HLB Difference ≤ 5: When mixing two emulsifiers, the HLB value difference should not exceed 5, otherwise stability will decrease.   Arithmetic Arrangement for More Stability: For example, mixing emulsifiers with HLB values of 6, 8, 10, and 12 in the correct proportions will yield better stability than a random combination.   Clear Prioritization: O/W emulsifiers primarily use water-soluble emulsifiers, while W/O emulsifiers primarily use oil-soluble emulsifiers. Other emulsifiers are added in a decreasing order of HLB value.   Invisible Effects of Temperature and Concentration: At high temperatures or high concentrations, the actual HLB value of an emulsifier will decrease. Therefore, the mixing ratio should be slightly higher than the theoretical required value to avoid performance degradation.   2. Water-based cutting fluid: practical analysis of 3 major types and 7 subcategories A. Comparison of three major types:   Type Particle size Advantage Fault Emulsified cutting fluid 1-10μm Strong cooling and low cost Easy to corrupt, poor lubricity Microemulsion cutting fluid ＜0.1μm High stability and long life Oil content and extreme pressure properties need to be enhanced synthetic cutting fluid 0.01-0.1μm Oil-free, strong cleaning Requires additional rust protection, easy to corrode guide rails   B. Seven sub-categories of market application scenarios:   Extreme pressure type: Contains sulfur, phosphorus, and chlorine additives and is suitable for heavy cutting (such as stainless steel machining), but copper corrosion issues should be avoided. Microemulsion: Contains only 10-30% oil, offering greater stability than traditional emulsions and suitable for precision machining. Fully synthetic fluid: This is an oil-free formula, but requires use with a guide rail protectant to prevent corrosion.   3. Industry Trends and Practical Case Studies Green Transformation: Demand for bio-based emulsifiers (such as soy lecithin) will grow by 35% by 2025, reducing carbon emissions by 40% compared to traditional products.   Case Study: Oleic acid diethanolamide: Adding 5% to copper wire drawing fluid increases the PB value to 800N while also solving the problem of wire shrinkage. Demulsifier Selection: Xinjiang oil fields use magnetic nano-emulsifiers, which reduce wastewater oil content to less than 5mg/L and are recyclable. Market Data: China's metalworking fluid market is expected to reach 20.6 billion yuan in 2024, with microemulsions experiencing the fastest growth rate due to their stability advantages.     4. “3 Dos and 3 Don’ts” for Emulsifier Selection   Do's: Measure HLB values, control temperature differences, and maintain the primary/secondary ratio. Don'ts: Mix emulsifiers with vastly different polarities, ignore bacterial protection, and blindly pursue low costs.   Tip: Regularly test pH and bacterial counts, and replace any deteriorating emulsion promptly—saving a little money can lead to a big loss!      

With the advancement of the "dual carbon" goal, environmental regulations are becoming increasingly stringent, and traditional lubricant additives are facing elimination. The new generation of environmentally friendly technologies can not only meet regulatory requirements, but also help you save money!   1). Environmentally friendly additives VS traditional products: What is the core difference? ‌ Traditional additives contain harmful substances such as sulfur and phosphorus, which are prone to produce sludge and carbon deposits, while environmentally friendly additives have achieved breakthroughs through three major technical routes: Biodegradable technology‌ The latest synthetic ester additives can be decomposed by microorganisms by more than 90% within 56 days, which is much higher than traditional products (<30%) Case‌: A drilling fluid lubricant uses a plant-based formula, reducing waste fluid treatment costs by 30% Nano-friction reduction technology‌ Graphite/cerium oxide nanoparticles can reduce the friction coefficient by 15%-20%, and the actual emission reduction is 30%+ Automotive feedback‌: A brand of full synthetic oil + nano additives, the oil change cycle is extended from 25,000 kilometers to 32,000 kilometers Low-carbon production process‌ The company has reduced the carbon footprint of its products by 18% through process optimization and obtained international certification   2). Real case: How is environmental protection technology implemented? Scenario 1: Aluminum processing industry Pain point: Traditional cutting fluid pollutes the workshop environment, and the cost of waste fluid treatment is high Solution: Micro-lubricant (only 0.15ml/time) replaces cutting fluid to achieve three major benefits: 1. Aluminum chips are dry and have no oil residue, simplifying waste treatment 2. Plant-based formula reduces the risk of skin allergies for workers 3. The overall cost is reduced by 40% Scenario 2: Wind power gearbox Challenge: Traditional additives are prone to generate ash at high temperatures, corroding precision bearings Breakthrough: T-151 ash-free dispersant reduces bearing wear to ISO 4406 standard 16/14/11 level   3). Future trends: 2025-2030 technology roadmap Technology direction 2025 status 2030 target Biodegradation rate 80% (CEC standard) More than 95% (EU new regulations) Carbon emissions reduced by 18%-20% Full life cycle carbon neutrality Cost 15%-20% higher than traditional products and par with mineral oil Experts predict: By 2027, environmentally friendly additives will occupy 30% of the market share, especially in new energy vehicles, wind power and other fields with a penetration rate of more than 50%   4). Practical advice for industry professionals Procurement options: Look for CEC L-33 or OECD 301B degradation certification to avoid "pseudo-environmental protection" Product on-site management: Nano additives are preferred for high-temperature equipment (such as graphite lubricants that reduce noise by 2-10 decibels) Before changing the oil of old equipment, the system must be cleaned to prevent the reaction between new and old additives Cost calculation: Although the unit price is slightly higher, the extended oil change cycle + reduced waste treatment can reduce the overall cost by 10%-25% Environmental protection is not a burden, but an opportunity for technological upgrading! From wind power to automobiles, from factories to oil fields, the green revolution of lubricating additives is bringing real money.

Low-viscosity polyether (PAG) oils have good compatibility with HFCs and can be used as base oils to produce refrigeration oils.   PAG as a base oil for refrigerators with special gases: It is suitable for automobile air-conditioning compressors of R134a and other HFC products. It is used as a base oil for refrigeration compressors. After being matched with R134a in a certain ratio, it has good high-temperature and low-temperature solubility. The high-temperature solubility temperature is 0-80°C and the low-temperature solubility temperature is 0-60°C.   Its advantages as a refrigerator base oil are as follows: ① Unique polyether end-capping technology, with R134a and various HFC refrigerants have excellent solubility; ② Intrinsic water repellency, not easy to produce capillary freezing problem; ③ Excellent viscosity index, can form a stable lubricating film at high temperature, with good lubricity; ④ Low viscosity at low temperature, with good fluidity and solubility; ⑤ Stable chemical properties, in high temperature and high humidity conditions There is also less decomposition.

The selection of cutting fluid is a key link that affects efficiency, quality and cost in mechanical processing. It is necessary to take into account the core requirements of the processing technology and the characteristics of the materials. This article will provide specific selection criteria and recommended solutions from multiple aspects such as processing technology classification and material characteristics to help achieve precise adaptation.   01   Processing technology adaptation   High-speed cutting: such as high-speed milling and turning, synthetic cutting fluid is preferred because it is composed of water-soluble additives, has excellent cooling performance, can quickly take away heat, and prevent tool overheating and wear and workpiece deformation.   Medium and low-speed cutting: such as ordinary turning, milling, and drilling, semi-synthetic cutting fluid is more suitable, balancing the cooling and lubrication requirements.   Heavy-load cutting: such as broaching and tapping, the pressure between the tool and the workpiece is high and the friction is severe. Semi-synthetic cutting fluid or emulsion containing special lubricating additives (such as extreme pressure additives) is required to reduce cutting force and tool wear.   Light-load cutting: such as simple plane milling and drilling, ordinary semi-synthetic or synthetic cutting fluid can meet the needs.   High-precision machining: For precision turning and grinding, synthetic cutting fluid or high-quality semi-synthetic cutting fluid should be used to ensure machining accuracy and surface quality.   02   Material adaptation   Ferrous metals: For example, steel and cast iron, emulsion, semi-synthetic or synthetic cutting fluid can be used, but attention should be paid to rust prevention. If the workpiece needs to be stored for a long time, it is recommended to choose semi-synthetic or synthetic cutting fluid containing high-efficiency rust inhibitor.   Non-ferrous metals: For example, aluminum and copper, which are sensitive to corrosion, water-based cutting fluids designed specifically for non-ferrous metals should be used to avoid surface discoloration or corrosion.   Stainless steel: It has a high tendency to work hardening and high cutting force, so semi-synthetic or synthetic cutting fluids containing special lubricating additives (such as sulfur and chlorine extreme pressure additives) should be used.   03   Tool characteristic adaptation   High-speed steel tools: Poor heat resistance, easy to lose hardness at high temperatures, and require cutting fluids with good cooling performance. Use water-based cutting fluids for high-speed rough cutting; use oil-based cutting fluids or high-concentration emulsions for medium and low-speed finishing to reduce friction and adhesion and inhibit the formation of cutting nodules.   Carbide cutting tools: good red hardness, but expensive, dry cutting is not economical. Generally, oil-based cutting fluids containing anti-wear additives are selected, and the tool needs to be evenly cooled to avoid sudden cooling and chipping. When cutting at high speed, a large flow of cutting fluid can be used to spray the cutting area.   Chorus fully synthetic cutting fluids are made of water-soluble plant polyesters, lubricants, rust inhibitors and other additives. They have excellent cooling, lubrication and cleaning properties, and are formulated according to different process requirements of customers. It provides strong extreme pressure lubrication performance, and the oil-free formula combines cutting and grinding to ensure tool cooling and clean processing environment. It has excellent performance even in extremely harsh processing. During the workpiece processing, it effectively avoids the problem of working fluid odor. The comprehensive cost is lower than that of microemulsion cutting fluids and emulsified oils, and it is easier to maintain and the workpieces after processing are also easy to clean.   Chorus semi-synthetic cutting fluids are refined with unique lubricants and composite additives, and are mainly used for cooling and lubrication during metal processing. It combines the advantages of synthetic cutting fluid and emulsified cutting fluid, has good lubrication and cooling effects, and has a long service life. It is an efficient, environmentally friendly and economical metalworking fluid, suitable for various metal processing occasions, can effectively improve processing efficiency, reduce costs, and extend the service life of equipment. It is an ideal choice for the metal processing industry.   Chorus water-soluble cutting fluid has excellent lubricity and anti-friction properties, which is very suitable for heavy-duty processing of aluminum alloys, automobile wheels and ferrous metals, significantly reduces tool wear, and greatly improves metal processing quality! Especially in the processing of ferrous metals, it performs well. Good antibacterial ability, maintains the long-term stability of the working emulsion, reduces odor, and keeps the workshop clean.

Terminal Guide: 3 Things Repair Shops Must Know Recognize the Mark ‌ : EV Special mark +GB/T 39288-2023 certification Refuse to mix ‌ : Dedicated filling equipment avoid cross-contamination Double cycle ‌ : Change every 20,000 kilometers (traditional oil every 10,000 kilometers) The actual measurement data of a certain chain express repair store: The motor temperature dropped by 13.2℃, the battery life increased by 2.1%, and the customer return repair rate decreased by 67%. V. The Future is Here: The Wealth Code of the 30 Billion Market. The China Lubricant Association predicts that by 2025, the market size of new energy-specific lubricants will exceed 30 billion yuan, with a compound annual growth rate of 67%, and the proportion of fully synthetic oils will exceed 85% "This is not a choice, but survival" - a purchasing director of a 4S store admitted that suppliers without EV fluid are being kicked out of the purchasing list.    

Common lubrication faults and countermeasures of lubricating grease   The correct selection of lubricating grease is the first step in ensuring the good operation of equipment. It is also crucial to analyze the cause of the malfunction and solve the problem in a timely manner when lubrication components fail. So what are the common faults encountered during the lubrication process, and how should these problems be solved? The main consideration here is the faults caused by lubricating grease. The same fault phenomena that occur due to other reasons will not be discussed here.   Abnormal equipment temperature exceeding the limit Phenomenon 1: When new or old equipment is replaced with new bearings, the temperature rises rapidly and high at the beginning of operation, but the temperature still exceeds the limit after running in. Fault analysis and countermeasures: ●Excessive amount of lubricating grease filling, generally only 1/2~2/3 of the bearing chamber needs to be filled with lubricating grease; ●If the viscosity of the lubricating grease base oil is too high or the viscosity of the lubricating grease is too high, it is necessary to replace the lubricating grease with a suitable viscosity; ●If the bearing speed factor (Ka × n × dm) is too large, it may be necessary to choose lubricating oil for lubrication; ●The bearing contains mechanical impurities such as particles, please replace the lubricating grease.   Phenomenon 2: The temperature rise of the bearing during normal operation is fast and high. Fault analysis and countermeasures: ●Failure of lubricating grease in maintenance free bearings, replace with new grease; ●The cycle of adding new grease to non sealed bearings is too long, and the lubricating grease is insufficient; ●The centralized lubrication system pipeline or distributor is blocked, resulting in insufficient grease supply.   Abnormal vibration and sound of equipment Phenomenon 1: The equipment experiences abnormal vibrations during normal operation. Fault analysis and countermeasures: ●Insufficient lubricating grease causes micro protrusions on the contact surface to collide with each other, resulting in high-frequency impact pulse vibration, deterioration of lubrication status, and peeling off of the bearing surface; ●Improper selection of lubricating grease, extreme pressure grease and grease with suitable viscosity should be chosen; ●Lubricating grease failure and blockage of the grease supply pipeline result in interruption of grease supply.   Phenomenon 2: Irregular abnormal sounds appear. Fault analysis and countermeasures: ●If the period and frequency of abnormal noise are irregular, it may be due to the failure of lubricating grease or the entry of impurities, and the lubricating grease should be replaced; ●If there is a certain pattern in the cycle and frequency of abnormal noise, it may be due to local damage to the bearing, and the bearing should be replaced   Damage to the rolling surface of the bearing Phenomenon 1: Bearing wear. Fault analysis and countermeasures: ●Excessive equipment operation load or loss of lubricating grease can cause wear on the friction surface due to boundary friction. You can choose products with high viscosity of extreme pressure grease or lubricating grease and base oil.   Phenomenon 2: Micro motion wear. Fault analysis and countermeasures; ●When bearings are in a slow swinging and stationary state, under strong external vibrations and high loads, small indentations and metal oxide powder are generated at the load-bearing parts of the shaft. You can consider using extreme pressure grease.   Phenomenon 3: Early fatigue pitting and bonding. Fault analysis and countermeasures: ●Oil film damage leads to early fatigue pitting or bonding. When the oil film of a medium speed running bearing is damaged, early fatigue pitting corrosion occurs under high contact stress and friction force; When the oil film of high-speed running bearings is damaged, it can cause adhesion and tearing of the bearing working surface. Extreme pressure grease or grease with high viscosity should be selected; ●The grease supply pipeline is blocked and the lubricating grease is insufficient.   Phenomenon 4: Corrosion. Fault analysis and countermeasures: ●Lubricating grease contains metal corrosion components and should be replaced with new grease.
