Centrifugal pump: insufficient oil level
Thread Content
It started working normally, but later there were several instances when the oil level could not be seen through the oil gauge window; no oil leakage was observed, the oil filler cap was full, and there was no oil top-up occurring. There were no abnormalities when the bearings were inspected, and eventually everything returned to normal. What could be the reason?
The oil level is too high, and the shaft bearing housing is tilted
The vent hole of the oil cup is blocked or the oil cup is too high
A rotary vane pump, right? They’ve all gone to the inner wall of the bearing box
No, it’s an ordinary centrifugal pump
Is the oil level gauge window clear, and is there a situation where the oil level is so high that it cannot be seen through the window?
Remove the plug at the bottom of the bearing housing to check if there is oil. If there is oil, check whether the oil reservoir needs to be refilled. If refilling isn’t necessary, examine whether there are any issues with the ventilation holes in the oil reservoir and the bearing housing.
Is it impossible to see the oil level in the gauge window at all? Could it be that the position of the oil view window is not designed properly?
