Introduction slide the working principle of the pneumatic valve type vacuum pump ( 3)

rotary vane pump is stuck in the rotor slot. Although sliding pneumatic valve type vacuum pump to overcome this defect has a certain degree of, at present, widely used in the vacuum industry of oil seal type vacuum pump are mostly medium and small TAB, the largest of the pump and pneumatic valve type vacuum pump. Rotary vane pump under the condition of the dirty work. But as a result of sliding pneumatic valve centroid relative rotary center distance is not a fixed value, while the structure balance has taken some measures, but still cannot achieve full balance, so the vibration is difficult to complete. Especially the capacity of the pump, the greater the vibration is also bigger. At the same time, the above two kinds of pumps, especially slippery pneumatic valve pump displacement versus the external dimensions appear larger.
when the pump structure difference. Slide extraction principle of the pneumatic valve type vacuum pump is similar to the vane pump.
so called huafa industrial pump. Slide although pneumatic valve type vacuum pump is a kind of old pumps, sliding pneumatic valve type vacuum pump is the main use of pneumatic valve device to change the west chamber volume. But compared with rotary vane pump, etc, has allowed work pressure high ( Pa large swept volume, can work continuously under the bad environment, durable and so on outstanding characteristic, so the vacuum smelting, vacuum drying, vacuum impregnation, vacuum distillation and other industries widely used.
