Some questions regarding light-duty centrifugal pumps
Thread Content
The oil in the centrifugal pump’s oil reservoir sometimes turns red, and sometimes the inner surface of the reservoir appears dirty, as if covered with a layer of oil residue. In these two cases, is it necessary to change the oil immediately? There’s also the situation where the oil level gauge shows no oil, yet the oil reservoir is full. Is it possible that the oil reservoir isn’t supplying oil? How can one determine whether the issue lies in a blocked oil pipe or some other problem?

In these two cases, is it necessary to change the oil immediately? It needs to be replaced. There’s also the situation where the oil level gauge shows no oil, yet the oil reservoir is full. Is it possible that the oil reservoir isn’t supplying oil? How can one determine whether the issue lies in a blocked oil pipe or some other problem? You’re using a constant-level oil cup, right? Stop the machine to check the oil level indicator and the oil cup
The reddening is likely due to a problem with the quality of the oil; it may be related to its oxidation stability, and the discoloration could be caused by oxidation. As for not having enough oil, it’s likely that you’re not filling it in the correct way; you need to first fill the oil chamber with the appropriate amount of oil, then add more oil to the oil reservoir and secure it onto the corresponding oil reservoir holder.
Oil oxidation causing redness is a normal phenomenon; especially in sunlight, it turns red quite quickly.
It’s normal for the L-AN46 machine oil to turn red after some time; check the oil sight glass and the location of the oil reservoir
