Detailed introduction to the working process of Roots blower!

First, let's look at the working process of Roots blower.

Roots blower is a positive displacement blower, which is used to compress and transport gas. Its working principle is based on the movement of two rotors.

There is some clearance between the two rotors, but they are not in direct contact. This is very important because this gap allows the gas to be sucked in and pushed.

The two rotors are driven by a pair of synchronous gears, and their motion directions are opposite. One rotor rotates clockwise and the other counterclockwise.

When Roots blower starts, the gas enters the air inlet first. At this time, the movement of the rotor makes the air inlet isolated to prevent gas backflow.

Next, the opposite movement of the two rotors pushes the inhaled gas to the exhaust port. In this process, the gas is continuously moved, but will not be compressed internally.

When the gas reaches the exhaust port, a special phenomenon occurs. Because there is high-pressure gas backflow at the exhaust port, the gas will be additionally pressurized.

This completes the gas transmission process.

In short, the working principle of Roots blower is to use the reverse movement of two rotors that are not in contact with each other but have clearance to push the gas from the air inlet to the exhaust port. This structure enables the gas to be transported without being compressed internally, while the high-pressure gas backflow at the exhaust port increases the pressure of the gas and completes the task of gas transmission. This mechanism makes Roots blower very useful in many applications.
