Temperature of the bearing at the drive end of the process liquid oxygen pump is rising
Thread Content
A spare liquid oxygen pump was installed, and it was observed that the temperature at the bearing end would rise after some time; applying grease would lower this temperature, but it would rise again after a few days. The vibration levels are normal
Is there any abnormal noise? If so, it’s best to take it apart and check it. Check if there are any issues.
There are no abnormal noises; it just seems to consume fuel quite quickly
Is this related to the pressure and flow rate of the sealing air for the motor?
There are no abnormal noises; it’s best to open it and check to confirm whether the motor lubricant has spilled onto the internal coils of the motor. Clarify the sealing type of the liquid oxygen pump? Treat the symptoms.
Thank you; the problem is that there’s no chance to stop right now
What is the temperature shown? A temperature within 40 degrees above the ambient temperature is considered normal. I can roughly guess what brand your liquid oxygen pump is; this type of pump has this issue of high bearing temperatures, but it doesn’t affect its functionality. There are also time requirements for applying lubricant.
Is the quality of that grease not very good? It’s best to use the grease specified by the manufacturer
If possible, it’s better to take it apart and check it.
