工作原理
How it works
螺杆真空泵利用一对螺杆在泵壳中作同步高速反向旋转,进而产生吸气和排气作用。两螺杆经精细动平衡校正,螺杆与螺杆之间都有一定的间隙,因此泵工作时,相互之间无摩擦,运转平稳,噪声低,工作腔无需润滑油
Screw vacuum pumps use a pair of screws to rotate synchronously and reversely in the pump casing, resulting in suction and exhaust effects. The two screws are corrected by fine dynamic balance, and there is a certain gap between the screw and the screw, so when the pump works, there is no friction between each other, the operation is stable, the noise is low, and the working cavity does not need lubricating oil
