The working principle and characteristics of Roots blower are illustrated in detail and worth collecting!

Roots blower is a positive displacement rotary blower, the main power source is motor and diesel engine as well as motor diesel hybrid type. The selection of main parameters needs to provide air flow, pressure, speed and motor power. Xin Qianshun will share its working principle with you today. Now, from the structural form and working principle of Roots blower, as well as matters needing attention, Let's explain the working principle of Roots blower in detail.

1. Structural form

As an ordinary three leaf roots blower, it is mainly composed of the head and the drive engine. The power data source can be the drive engine, motor and diesel engine. However, the main working component of roots blower is the head. Only through regular operation can the roots blower achieve the ideal state of gas transmission.

Then if we want to understand the basic working principle of Roots blower, we need to have a full understanding of the head structure of Roots blower.

The following figure is a clear explanation of the structure of Roots blower. The head of Roots blower mainly consists of one part: wallboard, casing, driving impeller, driven impeller, driving driven gear, main and auxiliary oil tanks and bearings, as shown in the figure:

2. Operating principle

The Ross fan has two impellers (Figure 2, ring part). Under the motor, the two impellers rotate in opposite directions. When the impeller enters the air inlet, the two impellers form a sealed chamber with the wall plate and the shell. The impeller continues to rotate, and the air in the chamber is forced into the exhaust, so the external air reaches the destination through the intake and exhaust repeatedly.

There will be a certain gap between the Roots blower impeller and the impeller, between the impeller and the wall plate, between the impeller and the housing, and the gap will have a fixed standard and error. If the error is too large, other corresponding problems will occur. When the impeller passes through the exhaust port, under the effect of the pressure in front of the pipe, some gas will leak to the outside through the gap, which is called internal leakage.

This is the working principle of Roots blower:

3. Precautions

Roots blower is a positive displacement fan, so the air volume will not change after operation. Even if the front pressure changes slightly, it can continue to deliver air.

After a period of use, the air volume system of Roots blower will change. Generally, the air volume can be reduced. The main reason for this phenomenon is that the clearance between the impeller and the impeller, the clearance between the impeller and the wallboard, and the clearance between the impeller and the casing have changed greatly, which increases the risk of internal leakage, thus affecting the air volume of Roots blower.

In order to ensure the normal operation of the rotating fan, other parts of the fan also play a very important role in bearings, gears, etc. If the working parts have abnormal faults, it will also have a great impact on the operation of the fan. Therefore, in the future use and maintenance, not only important parts should be carefully maintained, but also other matching parts should be regularly maintained!

The working principle of the root fan is very simple. With some pictures, we can clean and understand its working principle. When we understand the working principle of the root fan, we should first master its basic structure, and then the working principle of Roots blower, so that we can grasp the working principle of the root fan well.
