Detailed discussion on the pressure resistance of Roots blower

Source: Roots blower manufacturer Published on: December 16, 2021 Hits:

Roots blower is a positive displacement rotary fan, so the pressure of the front pipe is the pressure of Roots blower, and the pressure gauge represents the pressure of the front pipe. Generally speaking, the pressure of Roots blower actually refers to the compression capacity of Roots blower. That is to say, Roots blower can bear huge pressure and cannot bear specific pressure value. Roots blower reverses, causing the motor to burn.

Replacing the motor is both a direct and an effective method. With the replacement of motors with the same base number and higher power, the compression capacity of Roots blower increases directly and effectively. Moreover, this is often an effective method that does not change the base number of Roots blower.

Under specific pressure, if the large parameters of the fan have been exceeded, directly replace the Roots fan with a larger size, which is also a safe way to resist the excessive pressure of the pipeline.

Many netizens commented that the speed of Gouluo fans can increase the pressure of Roots fans. It is explained here that modifying the rotating speed of Roots blower can only change the air volume of Roots blower, and has no effect on the pressure rise.

Can the pressure be increased by changing the pulley? Replacing the pulley is a way to modify the speed of Roots blower, so it is impossible to increase the pressure.

What if the Roots blower is overpressure. Overpressure and under pressure are two different things. I have been talking about the problem of insufficient pressure. How to increase pressure? The roots blower does not need to be replaced for overpressure. It is OK to install a branch pipe on the pipeline and reduce the pipeline pressure. However, there is a disadvantage in doing so, that is, it cannot save energy.

Pressure resistance of Roots blower

1. Mechanical failure

Do not use it when there is a fault. Even if there is a slight fault, some customers' fans have faults. Some manufacturers require customers to continue to operate and use them, and purchase new ones after the operation is broken. Some customers may encounter this situation.

2. Intake air temperature exceeds 40 ℃

Generally, if the inlet air temperature of the cast iron three leaf roots blower exceeds 40 ℃, the three leaf roots blower will have problems. Therefore, if the inlet air temperature exceeds 40 ℃, the three leaf roots blower cannot operate normally.

3. The conveying gas is toxic

Toxic gas will not be transported by three leaf roots blower generally, and even if it is specially sealed, it is also dangerous.

4. The conveying gas is flammable and explosive

Transporting flammable and explosive gas requires special treatment of three blade roots blower, and it is forbidden to transport three blade roots blower without special treatment.

I believe that after reading the above content, you should also have a better understanding of the pressure resistance of Roots blower, and I hope it will be helpful to you.
