Rotary vane vacuum pump features

Rotary vane vacuum pump is an oil seal mechanical vacuum pump, its smart, low noise, easy to operate and other features make it more widely used in the vacuum pump. Rotary vane vacuum pump Next, the main features of the rotary vane vacuum pump. The working pressure range of 101325--1.33 × 10-2 (Pa) belongs to the low vacuum pump. It can be used alone or as a foreline pump for other high-vacuum or ultra-high vacuum pumps. It has been widely used in metallurgy, machinery, military, electronics, chemicals, light industry, petroleum and pharmaceutical production and research departments. Rotary vane pump can be sealed off the sealed container of dry gas, if accompanied by gas-town device, you can also pump a certain amount of condensable gas. However, it is not suitable for the extraction of gases that are highly oxygenated, corrosive to metals, react chemically to pump oils and contain particulate dust. Rotary vane pumps are one of the most basic vacuum acquisition devices in vacuum technology. Rotary vane pump for small and medium-sized pump. Rotary vane pump has a single-stage and two-stage. The so-called two-stage, is the structure of two single-stage pump in series. Generally made more double-stage, in order to obtain a higher degree of vacuum. The relation between pumping speed and inlet pressure of rotary vane pump is as follows: Under the inlet pressure of 1333Pa, 1.33Pa and 1.33 × 10-1 (Pa), the pumping speed shall not be less than 95% of the nominal pumping speed of the pump respectively, 50% and 20%. Rotary vane pump mainly by the pump body, rotor, rotary vane, end caps, springs and other components. A rotator is eccentrically mounted in the cavity of the rotary vane pump, the outer circumference of the rotor is tangent to the inner surface of the pump cavity (both have a small gap), and two rotary vanes with springs are arranged in the rotor slot. Rotation, by centrifugal force and the tension of the spring so that the top of the rotary vane and the inner wall of the pump chamber to maintain contact with the rotor rotation of the rotary vane slide along the wall. In summary, rotary vane vacuum pump features very unique, for users, to understand its characteristics, the use of products and promotion of great significance. It is another way for industry professionals to explore its features as a way to enhance the competitiveness of this product.
