2、Structural advantages of Variable frequency roots vacuum pump

The Variable frequency roots vacuum pump has the following structure

1. 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.

2. sealing device

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

3. rotator

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

4. gearing

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

5. pump body

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

6、Introduction of Variable frequency roots vacuum pump characteristics

Variable frequency roots vacuum pumpfeatures include Smooth operation, Fan vibration is small., reliability, No lubrication required and Volumetric efficiency，the product looks beautiful.，the advantage is The structural form of the three-blade rotor and the reasonable structure of the air inlet and outlet in the shell make the fan have small vibration and low noise.、Simple structural design, stable and reliable operation and convenient maintenance. This enables it to maintain high working efficiency and stability in long-term operation.、Because of the design of three-blade rotor, the Variable frequency roots vacuum pump has little vibration and low noise during operation, and the operation is stable and reliable、In the process of air intake and exhaust, the Variable frequency roots vacuum pump will not produce air pulsation, which means that it does not need an additional buffer gas tank to output gas smoothly. This is particularly important for processes that require stable airflow.、It has high efficiency and can realize gas transportation and pressurization with low energy consumption.，based on the relative motion between the rotors, the gas is sucked from the air inlet through the rotation of the rotors, compressed in the pump cavity, and finally discharged through the air outlet, thus forming a vacuum in the pump cavity.，is a Variable frequency roots vacuum pump newly developed by hyde。

Variable frequency roots vacuum pump

Variable frequency roots vacuum pumpbelonging to a rotary vacuum pump.，in the course of work,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.。
