What are the current maintenance priorities for small hydraulic motors?
There are four kinds of problems in hydraulic final drive motors: one is "mental illness", which means that the hydraulic system works well and sometimes, the actuators sometimes have no action; the second is "sweating sweat", which means that the system leaks seriously; the third is "jitter disease", which means When the actuator moves, there is beating, vibrating or crawling; the fourth is "high fever", which means that the hydraulic system working oil temperature rises too high. How to effectively control the above problems,
1 Controlling oil contamination and keeping the oil clean is an important measure to ensure the normal operation of the hydraulic system. At present, due to serious oil pollution, hydraulic failures frequently occur. According to a large factory, 80% of hydraulic system failures are caused by oil contamination. Oil contamination also accelerates the wear of hydraulic components.
2 Controlling the temperature rise of working fluid in the hydraulic system is an important final drive part of reducing energy consumption and improving system efficiency. The hydraulic system of a machine tool, if the temperature of the oil changes a wide range,
The consequences are:
a. affecting the oil absorption capacity and volumetric efficiency of the hydraulic pump;
b. The system works abnormally, the pressure and speed are unstable, and the action is unreliable;
c. Increased leakage inside and outside the hydraulic components;
d. Accelerate the oxidative deterioration of the oil. https://www.spfinaldrives.com/
