What is the relationship between the size of the inlet and outlet of Roots blower and the air volume?

It is often seen in our daily life that blowers are used to deliver gas and ventilate, but what is the relationship between the size of blowers and their air volume? Let's follow the Roots blower manufacturer to understand.   Roots Blower As a rotary compression fan for compressing and conveying gas, it is widely used in aquaculture oxygenation, sewage treatment aeration, cement transportation and other aspects due to its simple structure and convenient manufacturing. It is more suitable for gas transmission and pressurization systems in low pressure occasions, and can also be used as a vacuum pump. As a common equipment in modern industry, do you know its import and export? Today, I will take you to know?

The inlet and outlet of Roots blower can be judged simply by the following methods.
1. General principles
Generally, roots blowers are top in and bottom out, or top in and side out, which is the intake and exhaust method of most roots blowers.
2. Inlet silencer
The inlet silencer will have a grid shaped air inlet, which contains a filter element. Open the inlet silencer to see the filter element. If there is an inlet silencer, it is the air inlet. The outlet silencer is tubular, without filter element and other silencing accessories.
3. Outlet pressure gauge
If there is no inlet and outlet silencer at the head, and if we see a place where a pressure gauge is installed, the exhaust port is the outlet, and vice versa. Through the above judgment, the import and export can be basically determined. Other methods can also see the belt rotation direction on the belt protective cover, and the import and export can be determined by the rotation direction.

4. Rotational speed of roots blower

In many places with ventilation, the speed of the blower is not very high, but the air volume of the blower in operation is really closely related to its speed, and the speed of the blower will also affect the size of the air volume. In general, the speed is proportional to the air volume of the blower, and the speed of the blower is large, The fan quantity of the blower will also become larger, and vice versa when the speed is small. It cannot be said that the air volume of the blower is related to the speed, but there is also an inevitable connection.

5. Size of inlet and outlet of Roots blower

As mentioned above, the air volume of the blower has something to do with the speed. The air inlet and outlet of the blower may not have such a blessing. When the air inlet of the blower is smaller, the air volume will be smaller, and the pressure of the blower will also be the same. If the air inlet is larger, the air volume of the blower will also change slightly, the air pressure of the blower will be smaller, and the air volume of the outlet will increase, If the air outlet is small, the opposite is true, but the air pressure of the blower will increase. Therefore, the size of the air inlet and outlet will affect the air volume and the air pressure of the fan.

6. Rotor of Roots blower

This must have something to do with it. The operation of the blower depends on the rotor. The rotation frequency of the blower rotor determines the air volume of the blower. Since the size of the blower rotor is fixed, if the distance between the rotor and the blower casing is 0.01mm or less, the air volume of the blower will increase, The pressure will increase accordingly. Due to technical limitations and considering various factors such as the service life and safety of the blower, it will be formulated in accordance with unified standards.

The above is the relationship between the size of the blower and its air volume introduced by Roots blower manufacturer. I hope it will be helpful to you. If you still have relevant knowledge to understand, you can come to consult us, and we will have professionals to answer for you.
