Mechanical jamming of oil pumps is a common fault situation. When mechanical blockage occurs in the oil circulating pump 02-125801-3, there may be these reasons:

1. 1)     The EH oil becomes dirty, and impurities in the oil enter the pump, causing blockage.
2. 2)     Damaged bearings on the motor or pump side, deviations in the machining dimensions of the bell housing, and misalignment of the coupling can all lead to misalignment between the motor shaft and the pump shaft, exacerbating the radial force imbalance of the shaft, and ultimately leading to jamming between the gear and the pump body.

Methods for handling mechanical blockage of circulation pump 02-125801-3:

• Separate the motor from the pump and start the motor separately to see if it can start normally. If so, manually rotate the pump shaft to see if it can rotate (the pump shaft is relatively tight, and there should be some resistance when manually rotating the shaft).
• Check that the oil supply pipes and valves are not blocked or leaking oil. Ensure that the supply pressure and fluid flow of the oil pump are normal.
• Check the transmission system of the oil pump, including transmission belts, chains, gears, and other components, to ensure that they are not damaged or stuck. Remove any obstacles that may get stuck in the transmission system.

In the power plant steam turbine and generator, there are many different types of pumps and valves available. Contact Yoyik if you need any.
