roots vacuum pump is always noisy, affect the production environment, is the reason? Today we're going to have a look at together.

1, the roots vacuum pump motor noise

good quality Qiao differ, the motor noise tends to cover up the noise of the roots vacuum pump, a fan noise is generally bigger, is usually caused by plastic deformation of fan; The second is to use the bearing noise caused by poor quality bearing.

2, roots vacuum pump noise 1 parts inside. Rotor collision

including rotor and rotor, the rotor and the pump body and rotor noise in a clash with side cover

main reason: insufficient rigidity of shaft, rotor and gear positioning of the radial displacement of the shaft, gear clearance is too large or too small, the bearing axial clearance is too large, etc.

2. The roots vacuum pump gear

the influencing factors of gear noise in addition to the processing precision of gear itself, and installation of two rotor shaft gear parallel

3. Roots vacuum pump bearing

in addition to the precision of the bearing itself, the design deficiencies may also cause the increase of the bearing noise, such as the bearing inner and outer ring installation interference amount is too large, axial stiffness is insufficient, lubricating oil is in short supply, and affected by dust, water, corrosive gas and liquid pollution, etc.

roots vacuum water pump noise in the process of operation, basic is the collision between the internal parts, such as wear and tear, and the easy sound components are easy to wear, so should the roots vacuum pump equipment regular maintenance and maintenance operation, focus on maintenance spare parts.
