The working principle of roots vacuum blower can be simply summarized into the following steps:
1.Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
2.Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
3.Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
By repeating the above steps, the roots vacuum blower can continuously suck in, compress and discharge air.This working principle enables roots vacuum blowers to produce high-pressure, high-flow airflow.

Roots blower pump is a positive displacement fan, also known as roots blower pump. It uses two blade-shaped rotors to make relative motion in the cylinder to compress and transport gas. This working principle makes the roots blower pump simple in structure and easy to manufacture. It is widely used in gas transport and pressurization systems in low-pressure situations. It can also be used Used as a vacuum pump. The rotor of a roots blower pump usually adopts an involute or epicycloid envelope design to ensure that the rotor maintains a very small gap during rotation, thereby reducing gas leakage.
Roots blower pump type
1.Single-stage Roots blower
Single-stage Roots blower is also called single-stage screw blower, which is a Roots blower that uses a single screw as the compression element. The single-stage Roots blower has a simple structure and reliable operation. It is a widely used Roots blower. Usually suitable for low pressure and low temperature applications, such as sewage treatment, food processing, etc.
2.Multi-stage Roots blower
Multi-stage Roots blowers are composed of two or more screws, mainly to increase the compression ratio of the blower. Since the single-stage compression ratio of the Roots blower is low, if a higher compression ratio is required, a multi-stage Roots blower needs to be used. Multi-stage Roots blowers are usually suitable for high-pressure and high-temperature applications, such as water treatment, metallurgy, etc.
Internal compression Roots blower The internal compression Roots blower installs two screws in a cavity and compresses the gas to the required pressure by rotating the two screws in the same direction. The internal compression Roots blower operates smoothly, has low noise and high efficiency. Moreover, the internal compression Roots blower can adjust the speed according to changes in flow rate to maintain high efficiency for a longer period of time.
External compression Roots blower The external compression Roots blower installs two screws in independent cavities. Through the counter-rotation of the two screws, the gas is compressed from the suction end to the exhaust end. Compared with the internal compression Roots blower, the external compression Roots blower has a more complex structure, but also has a relatively high compression ratio. External compression Roots blowers are usually suitable for high-precision applications that require high compression ratio and flow stability.

What are the disadvantages of roots blower?
roots blower for sale
Loud noise Roots blower is a positive displacement blower that works by compressing gas to transport gas. Due to this working method, the Roots blower will produce a certain amount of noise during operation. For large equipment, this noise will have a certain impact on the environment.
Heavy maintenance workload As a kind of mechanical equipment, Roots blower requires regular maintenance and upkeep during use. Due to the characteristics of its structure and working principle, the maintenance work of Roots blower is relatively tedious and complicated. This will increase the company's operating costs and the labor intensity of maintenance personnel.
Low efficiency Compared with other types of fans, such as centrifugal fans or axial flow fans, the efficiency of Roots blowers is relatively low. This means that when driven by a motor of the same power, the Roots blower may need to consume more electrical energy to produce the same air volume. This not only increases the company's energy costs, but also affects the operating results and service life of the equipment.

What is the difference between a blower fan and a regular fan?
The difference between blower and fan
Blowers and fans are similar in appearance, but the way they generate wind is different. A blower drives an impeller to generate airflow through the rotation of a motor, while a fan blows air through the rotation of blades.
Applicable scenarios for blowers and fans
The air volume of the blower is large, but the noise is also large. It is suitable for scenes that require large air volume, such as factories, ships, and other large space scenes, but it is not suitable for home use. Fans are lighter and less noisy, and are suitable for use in small-area scenarios such as homes and offices.
Advantages and disadvantages of blowers and fans
The advantages and disadvantages of the two are relatively obvious. Although the blower has a large air volume, it is noisy and large in size, making it inconvenient to carry. The fan is small and portable, but the air volume is relatively small, making it suitable for use in a comfortable environment. In actual use, the choice should be based on actual needs.
Root blowers is a positive displacement blower. Its working principle is based on the relative movement of two blade-shaped rotors in the cylinder to compress and transport gas. This kind of fan has a simple structure and is easy to manufacture. It is suitable for gas transportation and pressurization systems in low-pressure situations, and can also be used as a vacuum pump. The design and structure of the Roots blower ensure that it can effectively increase the pressure and flow of gas, and at the same time achieve precise control of gas flow and pressure by adjusting the rotation speed and angle of the impeller. This type of pump is popular for its unique operating mechanism and wide range of applications, especially where stable air flow and pressure are required.

Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.

Root blowers pressure range
According to different usage requirements, the pressure of the Root blowers can be adjusted between 9.8kpa and 200kpa.Within this pressure range, the Roots blower can work normally and meet various process requirements.Specifically, the pressure range of Roots blowers includes:
Low pressure range: The pressure is lower than 58.8kpa, including 9.8kpa to 58.8kpa.This type of fan usually uses air cooling, and is mostly designed with a single oil tank.
Medium pressure range: The pressure is between 58.8kpa and 98kpa.This type of fan requires water cooling, and most of them are designed with double oil tanks.
High pressure range: When the pressure exceeds 98kpa, especially when it exceeds 140kpa, double-stage pressure boosting technology is required to ensure stable operation of the fan under high pressure.

How does a roots blower pump work?
The working principle of Roots blower can be simply summarized into the following steps:
1.Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
2.Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
3.Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.
