Dynamic diagram explanation of the structure and working principle of Roots blower, collect!

Roots blower is a positive displacement rotary blower. Its main power source is motor, diesel engine or motor diesel hybrid type. Its main parameters are air flow, pressure, speed, motor power, etc. Today, I would like to share its working principle with you. This article will discuss the structure, working principle, and precautions of Roots blower, Explain the working principle of Roots blower in detail.

1. Structural form

An ordinary three leaf Roots blower is mainly composed of two parts: the driver is the power source of the blower, which can be a motor or a diesel engine, and the head is the main working part of the Roots blower. Through routine operation, the purpose of gas transmission can be achieved.

If you want to understand the basic working principle of Roots blower, you must have a full understanding of the structure of the head of Roots blower. The main contents of the head include: wallboard, casing, active impeller, driven impeller, active as driven gear, main and auxiliary oil tanks, bearings, etc. In order to have a clear understanding of the structure of Roots blower, A system structure diagram has been specially arranged for your reference, as shown in the following results:

2. Operating principle

The Ross fan has two impellers. Under the motor, the two impellers rotate in opposite directions. When the impeller enters the air inlet, the two impellers form a seal chamber with the wall plate and the shell. The impeller continues to rotate, and the air in the chamber is forced into the exhaust. Therefore, the external air reaches the destination through repeated intake and exhaust.

There are certain gaps between impellers, between impellers and wallboards, between impellers and shells, and there are certain standards and errors in the gaps. 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 blower, so the air volume will not change after it is put into operation, and it can continue to deliver air when the front pressure changes slightly.

After long-term development and use, the air volume system of Roots blower will change, mostly because the air volume can be reduced, which is mainly caused by the clearance between impellers, between impellers and wallboards, and between impellers

The clearance with the casing has changed greatly, resulting in an increased 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 Roots blower is very simple. You can clearly understand its working principle with some pictures. When you understand the working principle of Roots blower, you must first master its basic structure. Then master its working principle so as to better master the working principle of roots blower.
