The biggest hazard of pollutants is to cause corrosion

The increase in oil temperature will accelerate the oxidation and deterioration of hydraulic oil, and the acidic substances generated by oxidation will cause corrosion of metal components..

After selecting a suitable hydraulic oil, management and maintenance are very important during use, and the following points should be noted.(1) Environmental conditions: mainly based on ambient temperature; (2) Working conditions: oil pump type, working pressure, temperature, speed, oil and metal, adaptability of seals and coatings, system operation cycle and working characteristics, etc.; (3) ) The nature of high speed bearing hydraulic oil: the physical and chemical indicators, performance and characteristics of the oil; (4) Economy: the price and service life of the oil. ①

Prevent hydraulic oil from being contaminated: The biggest hazard of pollutants is to cause corrosion of equipment, block filters and orifices, accelerate oil aging and corrosion of components; ② Prevent air mixing: mixing air will cause cavitation, Noise and premature deterioration of the hydraulic oil, affecting the use; 　③ Prevent water mixing: the mixing of cooling water and steam will corrode the metal in the hydraulic system, accelerate the deterioration of the oil, and reduce the lubricity of the hydraulic oil; 　 ④ control Operating temperature of hydraulic oil: For mineral oil hydraulic oil, it can work continuously at 50-65℃, and the highest operating temperature is 120-140℃
