What should pay attention to when replacing aluminum alloy elevator hydraulic oil

The hydraulic system of the aluminum alloy elevator is responsible for the smooth operation of the whole machine. It is also necessary to learn how to replace the hydraulic oil during use. The following tips hopefully will help everyone:
1: Turn off the power and check all hydraulic lines and fittings. Whether the pipe is damaged or if the joint is loose, all joints must be tightened.
2: Remove and disassemble the lowering valve, blow the net with compressed air, and then put it in and re-install it.
3: Put the hydraulic oil out, tighten the joint and take out the oil filter. After cleaning, clean it with compressed air, put it back in the tank, and connect the pipeline.
4: Replace with new oil and do not use old oil intermittently. Otherwise, moving parts in the system will accelerate wear.
5: Clean the dust on the platform of the hydraulic lifting platform to avoid short circuit or leakage. After use, it was found that the oil of the hydraulic oil is darkened, the oil is sticky, or the oil contains gravel and other foreign matter, and should be replaced.
6, aluminum alloy elevator check roller, intermediate shaft and bearing, cylinder pin and bearing, arm hinge axis and bearing wear.
