Why does oil leak from the top of the bearing housing in multi-stage centrifugal pumps? The fuel tank level is also around half, right? What’s the situation here? How should it be solved
Problems existing: 1. Poor airflow in the breathing mask; 2. Incorrect selection of the breathing mask; 3. Poor sealing at the threaded connections of the breathing mask – re-wrap with PTFE tape. Solution: 1. Clear the breathing mask passage ； 2. Replace with a suitable breathing mask
It’s not possible to tell what kind of nut this is. It is recommended to disassemble and clean all screw connections, and then use tape to seal the threads. For reference.

Senior, it seems that your company has a high level of 6S or 7S management! :P
Wrap Teflon tape around the threads of the respirator and the bearing housing to prevent leakage; for leaks at the threads and the respirator cap, a fine filter screen can be placed inside those threads
