What is a Negative pressure Roots blower? Introduction to the advantages, characteristics, and principles of the Roots Blower

Negative pressure Roots bloweris a device that generates positive pressure or negative pressure through the relative rotation of two impellers, thus compressing and conveying gas.，it has been widely used in power, pottery and porcelain, Food and beverage processing, port, coal chemical industry and other industries，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 Negative pressure Roots blower 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.、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 Negative pressure Roots blower perform well in many situations where stable airflow is needed.、Small size and small floor space make it easy to arrange and install in places with limited space.、Simple structural design, stable and reliable operation and convenient maintenance. This enables it to maintain high working efficiency and stability in long-term operation.，the product looks beautiful.，was developed and designed by hyde powder。

5、Structural advantages of Negative pressure Roots blower

The Negative pressure Roots blower structure is introduced as follows:

1. impeller

It is the rotating part of the Negative pressure Roots blower, which is divided into two leaves and three leaves. However, due to many advantages such as smaller air pulsation, less noise and smoother operation, the three-leaf Negative pressure Roots blower has gradually replaced the two-leaf Negative pressure Roots blower.

2. bearing

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

3. 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.

4. case

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

5. impeller

It is the rotating part of the Negative pressure Roots blower, which is divided into two leaves and three leaves. However, due to many advantages such as smaller air pulsation, less noise and smoother operation, the three-leaf Negative pressure Roots blower has gradually replaced the two-leaf Negative pressure Roots blower.

Negative pressure Roots blower

Negative pressure Roots blowerthe 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 Negative pressure Roots blower less vibration and noise.、It has high efficiency and can realize gas transportation and pressurization with low energy consumption.、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 blower has little vibration and low noise during operation, and the operation is stable and reliable、Due to the adoption of synchronous gear transmission and small gap design, the Negative pressure Roots blower runs stably and reliably, without contact and wear parts, and has a long service life.，is a Negative pressure Roots blower，multifunctional, with functions such as exhaust emission, material fluidization, pick up the suction, desulfurization oxidation and ventilation。
