FAQ
What is the maintenance frequency of the hydraulic pump?
The maintenance frequency of the hydraulic pump is usually performed every 1000 to 2000 hours of operation or once a year according to the manufacturer's recommendations.
How to maintain the excavator's swing bearing?
Regularly lubricate the swing bearing, check if the grease is sufficient, inspect the bearing for wear or looseness, and adjust or replace it if necessary.
How do you know if the perpendicularity between the ground gear plane and the bearing hole has changed?
It can only be found when assembling the gear pump, because the end face clearance is very small, generally around 0.05mm. If the perpendicularity between the end face and the bearing hole has changed, the gear shaft cannot move after the pump is assembled. If the locking screw is loosened a little, but it still does not turn smoothly, and the gear pump is disassembled and inspected, there are scratches on the end face. This is caused by the end face plane not being perpendicular to the bearing hole.
What causes the efficiency of hydraulic pumps to decrease?
The reasons for the decrease in efficiency include wear of internal components, filter blockage, hydraulic oil contamination and insufficient system pressure.
