High pressure pump noise analysis


High-pressure pump is to provide high-pressure rotary spraying slurry with high voltage power equipment, is now widely used in building, highway, plumbing facilities construction, but using a high pressure pump, high pressure pump gear frequently, noise, then the high-pressure pump gear in the cause of the noise and how to solve the problem of the noise of the small make up today for you reading.

A, high pressure pump gear noise has the following possible aspects:

(1) Impact of rotary plate on cylinder body, sound of residual volume of gear high pressure pump and pressure oil in exhaust dead gap;

(2) Impact of exhaust valve disc on seat and support parts;

(3) Echoes and bubbles bursting in the box;

(4) Bearing noise;

(5) Noise caused by large amount of gas and oil impact damper;

(6) Others. Such as transmission caused by noise, air - cooled gear high - pressure pump fan noise.

(7) Motor noise, which is a crucial factor.
