Introduction to Negative pressure Roots vacuum pump and blower advantages and features

Negative pressure Roots vacuum pumpis a positive displacement blower.，the main structure includes fuel tank, muffler, wallboard, case, bearing and so on，Negative pressure Roots vacuum pumpSimple structure and advanced technology.。The following is to introduce the Negative pressure Roots vacuum pump:

1、Brief introduction of Negative pressure Roots vacuum pump

Negative pressure Roots vacuum pumpis a device that generates positive pressure or negative pressure through the relative rotation of two impellers, thus compressing and conveying gas.，is a common Negative pressure Roots vacuum pump，is carefully developed by hyde powder combined with advanced technology。

3、Negative pressure Roots vacuum pump characteristics

Negative pressure Roots vacuum pumpit has the characteristics of convenient manufacture, wide application range, be of simple construction, convenient manufacture and durable performance，is a popular Negative pressure Roots vacuum pump，in the course of work,It mainly depends on the relative movement of two lobed rotors (usually three-bladed impellers) in the cylinder to compress and transport gas.。

4、Working principle of Negative pressure Roots vacuum pump

Negative pressure Roots vacuum pumpat runtime,Gas is compressed and transported based on the relative motion of two lobed rotors in the cylinder. When the two rotors rotate, the volume between them changes constantly, thus realizing the suction, compression and discharge of gas.。

6、Negative pressure Roots vacuum pump structure

The Negative pressure Roots vacuum pump structure is introduced as follows:

1. case

It mainly plays the role of supporting (wallboard, impeller, muffler) and fixing. The casing is the external structure of the Negative pressure Roots vacuum pump, which is used to support and fix the rotor, bearings and other components, while ensuring the gas tightness.

2. fuel tank

Mainly used for storing lubricating oil used for lubricating gears and bearings. The oil tank is used to store lubricating oil to lubricate bearings and gears and reduce wear and friction.

3. bearing

It is used to support the rotation of the rotor and bear the weight of the rotor and the load during operation.

4. wallboard

It is mainly used to connect the casing with the impeller, support the rotation of the impeller, and play the role of end sealing.

5. muffler

Used to reduce the noise caused by airflow pulsation when the Negative pressure Roots vacuum pump enters and exits.

Negative pressure Roots vacuum pumpSmall size and small floor space make it easy to arrange and install in places with limited space.、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.、Because of the design of three-blade rotor, the Negative pressure Roots vacuum pump has little vibration and low noise during operation, and the operation is stable and reliable、The structural form of the three-blade rotor and the reasonable structure of the air inlet and outlet in the shell make the Negative pressure Roots vacuum pump less vibration and noise.、In the process of air intake and exhaust, the Negative pressure 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.，at the start of the operation,The gas is compressed and transported by the relative rotation of a pair of trilobal rotors in the cylinder. Each trilobal rotor is supported by two bearings, and the relative position of the two rotors is always kept constant by using a pair of synchronous gears. During the rotation of the rotor, there are tiny gaps between impeller and impeller, impeller and casing, impeller and side cover, so there is no friction in the working chamber and no lubrication is needed, thus realizing the smooth transportation of gas.，is a double impeller synchronous compression machine, belonging to a positive displacement blower.。
