Vacuum pump price, pneumatic pump, pneumatic pump is a kind of vacuum pump, can make the gas continuous suction and discharge, so as to achieve the purpose of pumping, this kind of pump mainly has two types: variable capacity vacuum pump, it uses the periodic change of pump volume to complete the suction and exhaust process of vacuum pump, gas is compressed before discharge.

How much is the vacuum pump? The pump is divided into reciprocating and rotary vane: reciprocating vacuum pump is a pump that uses the piston in the pump cavity for reciprocating motion to suck, compress and discharge gas. Therefore, it is also called piston vacuum pump. Rotary vane vacuum pump: the piston in the pump cavity is used for rotary motion to suck in, compress and discharge gas. Rotary vacuum pump has the following forms.

Oil seal vacuum pump: it is a kind of rotary variable volume vacuum pump, which uses oil to seal the gap between moving parts and reduce harmful space. This kind of pump is generally equipped with gas ballast device, so it is also called gas ballast vacuum pump. According to its structural characteristics, it can be divided into the following five forms. Rotary vane vacuum pump: the rotor is installed in the pump shell with a certain eccentricity, close to the fixed surface of the inner surface of the pump shell.

There are two (or more) rotors in the rotor slot. When the rotor rotates, the vane can slide back and forth along its radial groove, and always contact with the inner wall of the pump shell. The vane rotates with the rotor, and the pump cavity can be divided into several variable volumes. Slide valve vacuum pump: a slide valve is arranged outside the eccentric rotor, and the rotation of the rotor drives the slide valve to slide and roll along the inner wall of the pump shell.

The upper slide valve rod of the slide valve can slide on the swing slide valve guide rail, and the pump chamber is divided into two variable volumes. Fixed piece vacuum pump: there is an eccentric rotor in the pump shell, which is close to the inner surface of the pump. There is a radial slide in the pump shell, which always contacts with the surface of the rotor. When the rotor rotates, the slide can slide up and down, dividing the pump cavity into two variable volumes.
