What is the reason for excessive vibration of centrifugal oil pump?
There are problems in installation and maintenance quality.
(1) Improper selection of gaskets and adjusting gaskets during the installation of the original unit, and excessive gaskets caused displacement of pump position in a certain stage of operation.
(2) Anchor bolts are loose.
(3) on the wheel coupling hole and the rubber ring combination hole is too tight, resulting in a forced combination, so that there is no room for automatic adjustment, rubber ring quickly wear.
(4) Bearing quality is poor, such as loosening of bearing seat hole and bearing outer diameter. Bearing beads and slideway have pitting or bearing tile cover tight force is insufficient.
(5) rotor mass imbalance.
(6) the matching gap between the coupling and the pump shaft, the impeller hole and the shaft is too large, or the matching gap between the impeller mouth ring and the pump body is too small.
(7) The balance plate and balance plate of multistage centrifugal oil pump are seriously worn or the same material.
(8) the pump is right, or the main shaft is bent.
(9) There are debris in the impeller passage of the pump body.
