Analysis of the reasons for fluctuations in multiple oxygen pumps

Let’s discuss it! The oxygen pump experiences fluctuations from time to time, in terms of its current and rotation speed, etc. We have analyzed the situation many times yet with no results; we suspect it’s an electrical issue, but we can’t provide any evidence. . . . . I wonder if anyone else has encountered this phenomenon; let’s analyze and discuss it together!
This question is difficult to answer, as many factors can cause changes in the liquid oxygen pump, such as electrical issues and instrumentation problems.
We have been there too. Some say it’s an electrical issue, while others claim it’s a problem with the signal transmission of the oxygen pump; there are different opinions, and no definite conclusion has been reached
Could you send the single-line diagram of the electrical system? If it’s an oxygen pump motor driven by an inverter, please also provide the information and setting values for the inverter.
What is the differential pressure between your oxygen pump seal gas and the reference gas? Try reducing it. But be careful about the exhaust temperature of the seal gas.
