Description
Technical field
The invention belongs to the maintained equipment fields of pump, and in particular to for the wiper mechanism of vacuum pump.
Background technology
Double shrouded wheel as depicted in figs. 1 and 2, has wheel disc 1, wheel cap 2 and receded disk impeller 3, is generally usually used in centrifugal
In compressor, vacuum pump.During by double shrouded wheel use to vacuum pump, the actuating unit of vacuum pump drives double shrouded wheel to turn
Dynamic, double shrouded wheel compresses the air for entering vacuum pump, is then discharged from vacuum pump, double shrouded wheel constantly with
Air contact during, the impurity in air can be adhered on double shrouded wheel, after vacuum pump is used for a long time, double shrouded wheel it is interior
Wall accumulates excessive impurity, can be significantly reduced the compression stroke of air, reduce vacuum pump vacuumizes efficiency.
Since double shrouded wheel is equipped with wheel cap 2, and the blade 4 on receded disk impeller 3 is in bending, it is difficult to using rag pair
Dust at the center of receded disk impeller 3 is cleared up, and the part cleaning for leading to receded disk impeller 3 is not clean, can shorten enclosed
The maintenance period of impeller；The efficiency that follow-up double shrouded wheel vacuumizes can be influenced simultaneously.
