Maintenance of Roots vacuum pump in application

The roots vacuum pump is a variable capacity vacuum pump with simple structure, large reserve capacity and easy maintenance. Daily maintenance work is simply to the bearings and gears to oil lubrication, maintenance costs are low.

Because the rotor profile of Roots vacuum pump is conjugate curve, its geometric symmetry is good. When the speed is not high, the working vibration frequency is lower than 80Hz, so the operation is stable and the noise is low. After replacing three roots pumps, the noise of 1575 paper machine was reduced, and the environmental noise pollution of the workshop basically reached the national environmental protection standard.

The paper sheet with certain humidity is formed by natural dehydration and forced dehydration of the web. Under the premise of small transverse shrinkage deformation, the pulp is normally and smoothly transferred to the press to further dehydrate the web by mechanical means.
