How to Solve the Problem of Abnormal Rotation of the Excavator?

Apr. 24, 2020

As a Komatsu Bucket Teeth Wholesale, share with you.

first, we first open the excavator to an open space. the purpose is to make the excavator have a rotating space, then straighten the arm and the bucket is one meter above the ground. the engine stops and the residual pressure is released.

幸运飞艇官方开奖计划second, someone pushed the bucket (the bucket left the ground) to move the excavator left and right. the person on the machine determines whether the abnormal sound comes from a rotating speed reducer or a rotating ring gear.

幸运飞艇官方开奖计划third, still use the pump to push the rotating ring gear of the excavator or make an abnormal sound, turn off the engine before the disassembled tubing is closed, and after removing the rotating ring gear, bring the excavator back to the upper mechanism of the removable mini excavator .

幸运飞艇官方开奖计划fourth, after removing the rotating ring gear, send it to a professional bearing factory. after grinding the ball track by increasing the size of the ball, it is normal to reinstall the rotating ring gear into the hardening device of the mini-digger.

this is how the problem of abnormal rotation of the excavator is solved. have you learned?

how to deal with power loss of hydraulic pump of excavator?

the most common failure of hydraulic pumps is the wear of the pump body and gears (basic type of component failure). the main reason for mechanical loss is that when oil flows in the pump, viscous resistance is generated due to the viscosity of the liquid, which also causes mechanical loss. this loss is related to oil viscosity and pump speed. the greater the oil viscosity, the higher the pump speed and the greater the mechanical loss. for the above reasons, the actual input power of the pump (the amount of work done per unit time by the reference object) is greater than the theoretically required power. the ratio of the theoretical input power to the actual input power of the hydraulic pump is called mechanical efficiency, which represents the degree of power loss.

the ratio of the output power of the hydraulic pump to the input power is called the overall efficiency of the hydraulic pump. when the hydraulic pump is working, there is mechanical friction between the relatively moving parts, such as between the bearing and the shaft, between the shaft and the seal, and between the vane and the inner wall of the pump.

This is the case about the power of the hydraulic pump of the excavator, I hope it will help you. Our company also has Komatsu Bucket Teeth for sale, please contact us.
