What are the common failures in the coupler maintenance
Common failures in coupler maintenance:
1. The oil temperature is too high in the maintenance and operation of the coupler.
(1) the selection of cold oil device is not reasonable, and the cooling capacity can not reach the actual work requirement。
(2) the cold oil device has long run scale and the cooling capacity decreases.
(3) the coupler work in the low efficiency area for a long time, and the calorific value increases greatly. (4) the tubing of the coupler is small, which affects the flow rate of oil.
2. The oil supply of the coupler is less than that of the bearing. The bearing lube oil supply is insufficient, which directly causes the bearing tile or burnout.
(1) the oil circuit design of the lubricating system is unreasonable;
秒速快3The quality of the oil is too poor.
3. The oil leaking in the coupler maintenance is a common problem in the power plant, which mainly occurs in two parts.
1. The oil leakage of the spoon pipe actuator is due to the unreasonable seal structure;
The shaft end of the coupler leaks oil, the reason is that the coupling of the coupler and the oil discharge cavity is sealed with copper teeth, and the seal gap becomes larger after wear.
4, the maintenance of pipe jam caused by coupling the pipe die adjustment system。
(1) the water contained in the oil caused the corrosion of the transmission parts to die;
(2) the improper limit of the execution of the motor, resulting in the death of the steering key of the spoon.
The clearance gap between the spoon tube and the spoon tube sleeve is small.
