Rotary vane vacuum pump rotary vane vacuum pump is equipped with a rotating rotor in the pump chamber for rotary motion, the vortex chamber separated by the working chamber chamber volume cyclical changes in order to achieve vacuum pump. Rotary vane vacuum pump in operation, due to various reasons will have a pleasant noise and noise, not only hinder the staff thinking, but also affect people's health. So how do these noise come from? How to put an end to it? Today Xiaobian to teach you the method! Rotary vane vacuum pump noise processing method Noise reasons: 1, parts have burrs, rotary vane vacuum chamber into the foreign body or rotary vane Deformation of the vacuum pump chamber noise caused by the operation of obstacles. 2, the spring break, rotary sound in the operation issued by the percussion. 3, rotary vane vacuum pump cavity lubrication, the issue of dry grinding noise; harmful space is too large, rotary vane vacuum pump itself; noise generated within the motor bearings, resulting in dry grinding noise. All of these make the rotary vane vacuum pump sometimes unpleasant sound. 4, Improper assembly, the friction sound when the rotor is running; the vane jumped out from the retracted rotor position and the vocal impact of the rotary vane vacuum chamber after strong squeezing from the end surface somewhere. Approach: The rotary vane vacuum pump inherent in the production of noise, it is not not repairable. Some chefs dredged some of the outlet that is slightly reaming to reduce the noise; some teachers will be separated plate diaphragm vane vacuum pump offset a few millimeters, reducing the harmful space, which can also reduce noise . For example, due to improper assembly, the end plate plane and the cavity is not vertical. This open the end cover, you can see the half-round arc on the end cover, indicating that when the vane through this site, was very powerful squeeze, and rotary vane vacuum chamber can not be normal contact. When the rotary blade is strongly squeezed through this part, it suddenly jumped out, and rotary vane vacuum chamber impact cyclical impact sound. They should take corresponding measures to eliminate them. For this problem, the cavity end face can be modified to make it perpendicular to the axial direction of the cavity, and the scratch on the end cover plate can be worn away. Then, the clearance between the rotary vane vacuum cavity, the rotor and the rotary vane can be adjusted, And adjust the telescopic performance of rotary spring, you can eliminate this fault. In short, as long as the fault identified, it is possible to eliminate excessive noise problems. However, it must not be ignored because a rotary vane vacuum pump may soon turn into a serious accident after sudden noise.
