| Abstract: | The performance of rotary plunger vacuum pump was restudied so as to propose a new concept of moving seal.The effects of the exhaust velocity and the size/shape of exhaust passage on the performance of pump were investigated.It was found that there is a new noise source for the rotary plunger vacuum pump,ie.,the collision between guide rail and slide valve rod.With the noise propagation and its shielding discussed,the way to decrease friction work is analyzed. |
