一台PY165B型平地机在使用过程中,出现液压泵、液压油箱等液压元件表面烫手的现象。为保证平地机有良好的工作性能,液压油的温度最好控制在55℃左右,连续作业时最高温度不应超过85℃。如液压泵、液压油箱等元件表面感觉烫手,说明系统的油温偏高,有可能引起液压油黏度下降,使系统的泄漏明显增加;油液的润滑性能下
A PY165B grading machine in the course of use, there hydraulic pump, hydraulic tank and other hydraulic components hot surface phenomenon. To ensure that the grader has a good working performance, the hydraulic oil temperature is best controlled at about 55 ℃, continuous operation, the maximum temperature should not exceed 85 ℃. Such as hydraulic pumps, hydraulic tanks and other components feel hot on the surface, indicating the system of high oil temperature may cause the viscosity of hydraulic oil decreased, the system significantly increased leakage; lubricating oil performance
