What is a Countercurrent cooling Roots vacuum pump? Introduction to the principle of the roots vacuum pump structure

Countercurrent cooling Roots vacuum pumpis a kind of vacuum equipment that uses a pair of rotors (usually two impellers with special profile) that rotate synchronously and reversely in the pump cavity to extract gas.，in the course of work,the suction, compression and exhaust processes are completed by synchronous high-speed rotation of two or more trilobal rotors in the pump cavity. The rotor consists of three blades, whose shapes and positions are symmetrical. When the motor is started, the two rotors start to rotate. Due to the symmetry of the design and position of the blades, air enters the pump body from the air inlet, and is gradually squeezed and discharged by the blades, forming a vacuum.。

3、Countercurrent cooling Roots vacuum pump structure composition

The Countercurrent cooling 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. rotator

Rotor is the core component of the Countercurrent cooling Roots vacuum pump, and its profile design and machining accuracy directly affect the performance and service life of the pump.

3. sealing device

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

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.

5、Countercurrent cooling Roots vacuum pump application

Countercurrent cooling Roots vacuum pumpIt is a product series that integrates vacuum drying, Vacuum extraction, Gas treatment, vacuum packaging and vacuum treatment，it is an ideal choice for customers to buy Countercurrent cooling Roots vacuum pump。

Countercurrent cooling Roots vacuum pump

Countercurrent cooling Roots vacuum pumpthe product looks atmospheric.，at 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.，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.、Small size and small floor space make it easy to arrange and install in places with limited space.、It has high efficiency and can realize gas transportation and pressurization with low energy consumption.、Simple structural design, stable and reliable operation and convenient maintenance. This enables it to maintain high working efficiency and stability in long-term operation.、Small size and small floor space make it easy to arrange and install in places with limited space.。
