The motor of the condensate pump vibrates severely
Thread Content
Our company has a new motor for a condensate pump; it hasn’t been turned on yet, but its horizontal vibration level is already 8.5 mm/s, while the vibration levels of both the foundation and the pump themselves are quite low. Could some expert please offer some guidance?
Check to see if the seismometer probe is in the right position! !
The foundation feet are loose; try to tighten them evenly again. If that doesn’t work, loosen the foundation foot that causes the most vibration.
Could you explain it more clearly? Is the vibration level 8.5 mm/s even when the motor is not running, or only when it is running?
First: When the machine is running, check the vibration levels in both horizontal and vertical directions of the front and rear bearings. Loosen the nuts one by one, then tighten them again; keep doing this until the vibration levels decrease. After that, shut down the machine and secure that area properly. Second: Check whether the motor bearings are damaged and replace them if necessary. Third: Perform dynamic balancing on the motor rotor. Eliminate the imbalance.
