From the use point of view, 2H sliding valve vacuum pump is suitable for pumping air and other general gases. When using air ballast, it can also suck a small amount of condensable gases (such as water vapor). Additional devices should be installed when pumping gases with excessive oxygen, explosive, corrosive to ferrous metals and chemical reaction to vacuum oil. The pump can be used alone or as a front-stage pump of high vacuum pumps such as diffusion pump, oil booster pump and Roots pump. Compared with rotary vane vacuum pump, 2H sliding valve vacuum pump is more durable and has long service life. The pump is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecular distillation and aviation simulation test.
From the product characteristics, 2H sliding valve vacuum pump is optimized weight, less vibration and low noise; bearing seal chamber is supplied separately from pump chamber to avoid premature damage of bearing and seal caused by impurities entering bearing chamber; according to user requirements, auxiliary oil tank can be attached to achieve the function of cooling vacuum oil to separate impurities; Except for the old H-150, the motors are all above the pump, compact in structure and occupy less space.
