Specializing in the working principle of Roots blower, the principle and process of fan operation

Roots blower is a common type of blower. In this article, we will introduce the working principle of the blower, the principle of the Roots blower and the process of three aspects of the Roots blower knowledge.

First, the working principle of the blower

A blower is a centrifugal fan driven by machinery or electricity. When the blower is activated, the wind pressure it generates can be used to raise the speed and pressure of air, gas and other substances. Specifically, a blower compresses air or gas by means of a rotating impeller, which is then transported through an exhaust line to a target location. In short, a blower is a mechanical device that generates pressure and flow.

Second, the principle of Roots blower

Roots blower is a volumetric blower. In layman's terms, it is the use of the gap between the two internal gears is constantly enlarged and narrowed, so as to compress the gas, to achieve the purpose of conveying gas. The principle of Roots blower is based on volumetric analysis, that is, when rotating along the circumference of the impeller, the volume change between the impeller and the inner shell is used to realize the compression and discharge of air.

Third, the working process of Roots blower

The working process of the blower is divided into three steps: air intake, compression and discharge. The process, accurate rotation and space control is an important key to the work of the Roots blower. The rough process is as follows:

1. When the blower is started, air enters through the air inlet of the blower.

2. After entering the blower, the air enters into the gap of the gears and the gears and liners are sealed together to form a pressurized confined space.

3. As the blower rotates, air is gradually compressed as the gears rotate and continues to flow forward.

4. As the air passes through the compression section of the blower, it is compressed to the desired pressure value.

5. Subsequently, at the outlet, as the gears continue to rotate, the air is depressurized and discharged in the expanding space around the inner shell.

6. Finally, the inner gear of the blower will be driven by the motor, and as the motor continues to rotate, the air will be pushed to the outside.

IV. Characteristics of Roots Blower

Roots blowers have the following main features:

1. Volumetric compression, stable pressure. Roots blower adopts the volume of internal gear clearance to realize gas compression, stable and reliable pressure.

2. Small volume, compact structure. Roots blower has a compact structure, has a small footprint and is easy to install.

3. Small vibration and low noise. During the operation of Roots blower, the vibration is small and the noise is low.

V. Application of Roots blower

Roots blower is a common blower, widely used in many fields, as follows:

1. Used in environmental protection: Roots blower can be used to deal with sewage and waste treatment plant.

2. Used in the chemical industry: Roots blowers can be used to improve the quality of products such as paints, due to the viscous nature of the paints, which also need to be compressed and transported by Roots blowers.

3. For food processing industry: Roots blowers can be used for crushing, drying and conveying food materials.

4. Used in Oxygen Plant: Oxygen plant production of oxygen requires a large amount of air compression, discharge, need to use the Roots blower to compress the air, and through the pipeline delivery.

5. Used in paper industry: Roots blower can be used in the paper machine in the breathable version and the printing machine of the paper transmission.

In short, Roots blower is a common blower with the characteristics of compression and conveying, which is widely used in many fields. Understanding the relevant principles and processes is an important help for us to use Roots blowers in our daily work.
