4、Working principle of Negative pressure roots vacuum pump

Negative pressure roots vacuum pumpat the start of the operation,mainly based on the relative rotational movement of the rotor in the pump chamber. There are two rotors in the pump, and a certain gap is kept between them and the inner wall of the pump shell. Through the rotation of the rotor, the gas is sucked in from the air inlet, and then discharged from the air outlet through the processes of compression and exhaust. Due to the special design of the rotor profile, the gas in the pump cavity is effectively compressed and discharged, thus achieving vacuum extraction.，belonging to a rotary vacuum pump.，is a kind of high quality and low price Negative pressure roots vacuum pump，It has a wide range of uses, including vacuum packaging, vacuum distillation, vacuum drying, Gas treatment and Vacuum extraction，low in price，reliable quality。

5、Structural characteristics of Negative pressure roots vacuum pump

The Negative pressure roots vacuum pump has the following structure

1. gearing

The transmission device is usually driven by motor or reducer, which makes the rotor rotate relatively in the pump cavity.

2. rotator

Rotor is the core component of the Negative pressure roots vacuum pump, and its profile design and machining accuracy directly affect the performance and service life of the pump.

3. bearing

Bearings are responsible for supporting the rotary motion of the rotor, and high-precision bearings are usually used to ensure the stable operation of the rotor.

4. sealing device

The sealing device is used to ensure that the gas in the pump cavity will not leak to the external environment.

5. pump body

Pump body is usually made of cast iron or cast steel, which has good strength and sealing performance.
