Kunlun HML long-life hydraulic oil | ||
Technical performance | Effect | |
Excellent oxidation resistance | Longer service life, more than 5 times the service life of ordinary hydraulic oil | |
Excellent abrasion resistance and rust resistance | Reduce equipment wear under harsh working conditions and ensure the normal operation of the pump under high temperature and high pressure | |
Excellent thermal stability | Reduce oil sludge formation and reduce oil color changes | |
Excellent anti-foaming and air release properties | Ensure that the system is sensitive, accurate and stable | |
Excellent demulsibility | When the system enters the water, the water is quickly released to ensure the efficient operation of the equipment | |
Excellent adaptability of sealing materials | Prevent oil leakage | |
