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.
In the selection of Roots blower, the pressure refers to the outlet pressure of Roots blower. First of all, because Roots blower is a volumetric type, it does not generate pressure itself. How does the pressure of Roots blower come from? In fact, it is the ability of Roots blower to overcome the pressure in the front pipe that we call "Roots blower pressure". The pressure of Roots blower depends on the outlet pipe and atmospheric pressure, so it must be noted that the Roots blower within the pressure must be selected when selecting the type of Roots blower. If the rated pressure is exceeded, the Roots blower will be in an overpressure state and may burn the motor, If the pressure of Roots blower is insufficient, it may cause the Roots blower to fail to achieve the effect we need.
1. Motor replacement is both a direct and 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.
2. 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.
3. 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.
4. 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.
5. What to do if 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.
I believe that after reading the above contents, you should also have a better understanding of the methods for improving the pressure resistance of Roots blower. I hope it will be helpful to you.
