Industry pain point: The difficulty in distinguishing between oil and water is like a bone stuck in the throat. The 2024 "China Industrial Lubrication White Paper" shows that 78% of hydraulic system failures are related to oil emulsification. The bearings of a certain wind power gearbox were pitted due to emulsified oil, and the single repair cost exceeded 2 million yuan. Emulsified oil not only reduces the lubrication performance but also triggers a chain reaction such as equipment corrosion and filter element clogging.
The core three methods break the deadlock
The first method: The thermal cell wall breaking method reduces the strength of the interfacial film through gradient heating (recommended at 80-120℃), and in combination with a vacuum dehydration device, it can achieve a moisture content of less than 500ppm. After the hydraulic station of the rolling mill of a certain steel group adopted this scheme, the oil product replacement cycle was extended from 3 months to 11 months.
The second method: Centrifugal stripping technique employs a three-stage centrifugal separation technology (8000-15000 RPM), achieving a removal rate of 99.7% for nano-scale emulsified water droplets. It is particularly suitable for the lubrication system of the stern shaft tube of ships. After a shipping company in Shanghai applied it, it saved more than 800,000 yuan in waste oil treatment costs annually.
The third type: Chemical demulsifier. The addition amount of the new polyether-based demulsifier is only 50-100 PPM, and the demulsification speed is three times higher than that of traditional products. After the injection molding machine in an oilfield in Shandong Province was put into use, the cleanliness of the oil products was stably maintained at NAS level 7.
