The bearing housing of the hot oil pump vibrates heavily!
Thread Content
After the bearing at the drive end of the hot oil pump was replaced, the vibration level was 2.2 mm/s; after 12 hours of operation, the vibration increased to 4.0 mm/s. The temperature remained unchanged, and the color of the lubricating oil became slightly cloudy. What could be the reason?
Bears are inevitably damaged during the installation process. Also, was your bearing lubricated with grease in its original condition? Has the bearing housing been cleaned thoroughly? Is the drive shaft damaged or deformed? Is the motor concentric with it? There are many reasons; look into it carefully
Is the improper alignment the reason for replacing the bearings?
It was finally determined that the compression bolts were a bit loose and not properly installed; thank you all!
