1: Ambient temperature and pollutants
If the environment is dusty, humidity, and temperature is high, it will promote oxidation or degrade the emulsified oil of the hydraulic support, increase the viscosity of the oil, residue and acid substances, and corrode the equipment.
2: Material of the workpiece processed by the equipment
The same equipment processes the workpiece of different materials, and the cycle of cleaning and replacing the emulsified oil of the hydraulic support will be different. For example, the oil change cycle of regular processing of cast iron workpieces is shorter than that of ordinary metal materials, because the cast iron powder cut down is easy to pollute the oil and catalyze the aging and deterioration of the oil.
3: The tightness of the equipment
Poor sealing, pollutants in the air, processed metal fragments and emulsion are easy to invade the system, accelerate the wear of the equipment, and the oil change cycle is short.
4: equipment operation time
The operation time is long, the cleaning and oil change time is short, if the single shift or the use efficiency is not high, the cleaning and oil change cycle is long.
5: The amount of fuel in the tank
The cleaning and oil change period of the ground equipment depends on the amount of oil injected in the tank, because the less the amount of oil injected, the higher the emulsified oil circulation speed of the hydraulic support, the shorter the residence time in the tank, the poor heat dissipation conditions, and the high oil temperature.
6: New equipment or overhauled equipment
Because the friction surface between the new processing surface and the new zero has a certain roughness, the actual contact area is small, the pressure per unit contact area is large, and the wear speed and wear amount are large in the beginning of operation for a period of time, so the operation is carried out for a cleaning oil change for 3 months, and then the oil change is cleaned according to the normal regulations.
