What are the reasons for the bearing oil cut

release time：2021/1/9 20:08:09

(1) Misoperation occurs when the oil system is switched during operation, and the monitoring of the lubricating oil press ends is strengthened to break the oil and cause the tiles to burn.

(2) After the unit starts the fixed speed, stop the speed control oil pump, pay attention to monitoring the pumping pressure, because the injector enters the air to work abnormally, the main

oil pump loses pressure, the lubricating oil pressure is reduced and not linked, and several aspects are combined , so that the bearing is cut off, causing the bearing bush to burn.

(3) The bearing bush is reversed during operation or shifted during operation.

(4) During the start and stop of the steam turbine generator set, the high and low pressure oil pumps fail at the same time.

(5) The main fuel tank oil level drops below the low limit. The air enters the enemy. Make the main oil pump work abnormally.

(6) The accumulation of a large amount of air in the oil system is not eliminated in time, so that the bearing bush is instantaneously cut off.

(7) The plant is interrupted by electricity. The DC oil pump cannot be injected in time.

(8) During installation or overhaul, the oil system retains cotton yarn and other debris to block the tubing.

(9) The unit will vibrate strongly, which will cause damage to the bearing bush.
