Rotary vane vacuum pump (rotary vane pump for short) is an oil seal mechanical pump, belongs to a low vacuum pump with working pressure range of101325~1.33×10-2(Pa)It may be used alone or as a pre-vacuum pump of high vacuum pump or other ultra-high vacuum pump. It has been widely used in production and scientific research departments, such as metallurgy, machinery, military, electronics, chemicals, light industry, petroleum and pharmaceutics.
Rotary vane vacuum pump technology is one of the most basic equipment to obtain vacuum.Rotary vane pumps are mostly small and medium sized pump. Rotary vane pump has two single-stage and two-stage. The so-called two-stage, that is, the structure will be two single-stage pump series. More dual-class, in order to obtain a higher vacuum. Rotary vane pump inlet pressure pumping speed and the relationship are as follows: if the inlet pressure is 1333Pa、1.33Paand 1.33×10-1(Pa)its pumping speed values are not less than 95%, 50% and 20% of the nominal pumping speed.

The rotary vane pump working principle diagram is shown as below. Rotary vane pumps are mainly made up of pump body, rotors, rotary vanes, terminal covers, springs and other components. Eccentrically mounted rotary vane pump chamber a rotor, rotor cylindrical surface tangent to the pump cavity (they have very small gaps), and the rotor slot with a spring with two rotary vane. Rotates, centrifugal force and spring tension against the inner wall and the top of rotary vane pump chamber to maintain contact, rotary vane rotor driven rotary slide along the inner wall of the pump chamber. |
