The temperature of the elevator pump rises too high for the following four reasons:
The matching gap between the moving parts in the pump is too small, so that the moving parts are in a state of dry friction and semi-dry friction, and a lot of heat is generated; the bearing is burned out; the oil distribution plate or rotor is ablated; between the rotor and the oil distribution plate The axial clearance is too large, the leakage is serious and the heat is generated.
The hydraulic pump is one of the very important parts of the hydraulic system of the stationary lift, which provides powerful power. As an important part of the elevator, the hydraulic pump is very important for its normal operation. As long as the hydraulic pump fails, it will affect the normal use of the lift.
In the common problems, there will be insufficient output flow or no flow output of the hydraulic pump. There are many reasons for the insufficient output flow of the hydraulic pump, but this needs to be repaired item by item. The reason for the overheating of the hydraulic pump of the fixed lift is that the mechanical efficiency is low or the volumetric efficiency is low. Due to the low mechanical efficiency and the large mechanical friction, the loss of mechanical energy is caused. Due to the low volumetric efficiency, a large amount of hydraulic energy is lost, and the lost mechanical energy and hydraulic energy become heat energy.
