The high-speed pump makes a lot of noise
Thread Content
Vertical high-speed pump with a speed increase of level 2, 110 KW; it generates significant noise at the installation site – the noise level was measured at 105 at a distance of 1 meter. The oil temperature and pressure are within normal ranges. Vibration is measured at four positions on the flange cover of the gearbox: 2.2/10.1/5/3 (mm/s2). I would appreciate guidance from everyone
The structure diagram has been sent – is it from No. 11?
I think the sliding bearing is ruined; I’ll take it apart to check
There are many possible reasons, so it’s hard to tell! !
Could it be vibrations caused by cavitation?
OP, the posting location is wrong; it should be posted in the Mechanical Equipment section.
The concentricity between the motor and the pump is poor; there is a problem with the rear pulley
