Causes and hazards of high temperature of hydraulic system
1, the harm of high oil temperature of hydraulic equipment Hydraulic oil itself has good lubricity and wear resistance characteristics, when the hydraulic oil temperature environment is not less than 35 ° C and not higher than 50 ° C, the hydraulic equipment can maintain the best working condition. Once the oil temperature of the hydraulic equipment is too high, or even exceeds the defined index, it is easy to cause the internal disturbance of the hydraulic system, accelerate the aging of the sealing parts of the h
