Oil level issue in the pump oil cup
Thread Content
It is a device used to supply oil to the bearing box when there is a lack of oil in the oil cup of the centrifugal pump. However, in our station, one of the pumps has a low oil level in its bearing box, and the oil in the oil cup is not replenished to the bearing box in a timely manner. Could everyone analyze the reasons?
This oil cup is an automatic oil filler! If oil isn’t added in time, it will get clogged! The suggestion is clear! If it still doesn’t work! It was replaced directly!
To add to what was said above: it’s possible that the oil level gauge itself isn’t being refilled with oil, and the blockage could also be at the connection between the oil level gauge and the fuel tank. If oil leaks when you lift the oil level gauge, then it’s likely that the connection is blocked.
1. There is a vent on the oil cup; is it blocked? 2. Is the slope of the oil cup in the correct direction? / 3. Is the horizontal pipe tilted? 4. Are the holes on the oil filling cap of the bearing box blocked? 5. Check for any blockages (from the oil cup to the bearing box)
The oil outlet (tilted tube) of the oil cup is too low, resulting in a too-low oil level surface that prevents timely refilling of oil.
During maintenance, check whether the oil pipe is unobstructed
Use a ruler to measure the oil level in the bearing housing, as well as the height of the inclined edge of the oil cup
It’s unlikely that the exhaust port of this oil filler will get clogged. If oil cannot be replenished in a timely manner, it’s because the height of the oil outlet of the filler is inappropriate – it’s too low – and a filler with an appropriate oil outlet height needs to be used.
1. The oil in the oil cup is used to determine the oil level in the bearing housing； 2. If the oil level in the oil cup does not decrease, but there is a lack of oil in the bearing housing, it indicates a blockage that requires repair.
Once you understand the principle of the constant-pressure oil cup, the solution becomes obvious.
It’s probably the line for filling oil that’s blocked, or the breathing hole is clogged. This is simply a matter of the principle of a communicating vessel: if there’s no blockage, then oil can’t be filled in
