What is a Large-flow Roots vacuum pump? Introduction to the advantages, characteristics, and principles of the the roots vacuum pump

Large-flow Roots vacuum pumpis a common vacuum equipment.，is designed by hyde powder with advanced technology。

1、Brief introduction of Large-flow Roots vacuum pump

Large-flow 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.，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.，at the start of the operation,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.，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.、The air volume is directly proportional to the rotating speed, so its air output is very stable and basically unaffected by pressure changes. This characteristic makes the Large-flow Roots vacuum pump perform well in many situations where stable airflow is needed.、It has high efficiency and can realize gas transportation and pressurization with low energy consumption.、Due to the adoption of synchronous gear transmission and small gap design, the Large-flow Roots vacuum pump runs stably and reliably, without contact and wear parts, and has a long service life.、Simple structural design, stable and reliable operation and convenient maintenance. This enables it to maintain high working efficiency and stability in long-term operation.，low in price，reliable quality。

4、Large-flow Roots vacuum pump structure

The Large-flow 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. pump body

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

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. rotator

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

5. gearing

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