Hydraulic systems are mostly composed of five parts, among which hydraulic medium is the working medium for transmitting energy in the hydraulic system. Water glycol fire-resistant Hydraulic fluid and 46 # anti-wear hydraulic oil are common hydraulic media in hydraulic system. What is the difference between water glycol fire-resistant Hydraulic fluid and 46 # anti-wear hydraulic oil? Water glycol Hydraulic fluid is a combination of ethylene glycol, organic polymer and other additives. It has good flame resistance, lubrication, cooling, low condensation and rust resistance. It is a water-based hydraulic medium, safe and environmentally friendly. And hydraulic oil is synthesized by combining Base Oil with various additives, which is an oily medium and poses a safety hazard. With the advancement of technology, traditional hydraulic oil can no longer meet the needs of hydraulic systems, and there are more and more types of hydraulic oil. Among them, 46 # anti wear hydraulic oil is one of them, which has good wear resistance. Due to the difference in the quality of hydraulic oil produced by different manufacturers, it is easy to cause fire and pollute the environment during use. At the same time, with the increasingly strict environmental protection requirements, hydraulic oil has gradually been replaced by water glycol Hydraulic fluid, which is widely used in hydraulic systems that are easy to access high temperature open fire in metallurgy, chemical industry, mining, power plant, mechanical processing and other industries, To avoid the occurrence of fire accidents caused by the leakage of traditional mineral oil hydraulic oil.
The difference between water glycol Hydraulic fluid and hydraulic oil For the water glycol fire-resistant Hydraulic fluid itself, attention should be paid to its compatibility with metals and nonmetals. During use, attention should be paid to the fact that it cannot be mixed with fat type, mineral oil and emulsion type media. The maximum operating temperature of open oil tank should not exceed 55C, and the maximum temperature of closed oil tank should not exceed 65 ° C. Regularly check the appearance, PH value, foam and other conditions of the product, To ensure the normal operation of the hydraulic system. If the original hydraulic system using hydraulic oil is changed to water glycol flame resistant Hydraulic fluid, the most important thing is to clean the hydraulic system. The principle is to drain the residual hydraulic oil in the hydraulic system as far as possible to remove the oil scale and sediment in the oil tank. It is better to draw out the plunger or piston of the working cylinder, drain the residual oil in the oil cylinder and oil tank, recycle the hydraulic system with oil stain cleaning agent, and finally circulate the Hydraulic fluid once to see if there is any change. If there is no change, continue to add Hydraulic fluid and start the hydraulic system.
