How to increase the pressure of roots blower? What is the maximum pressure of roots blower?

    Roots blower The pressure of depends on the resistance, and can work normally as long as it is within the acceptable pressure range. For example, when aerating in a pool with a water depth of 2 meters, the pressure of the air blown out is 20 kPa. At a depth of 3 meters, the pond becomes 30 kPa. As long as the motor output power can reach the load.

Insufficient pressure of roots blower may cause the following:
1. First, determine whether the motor wiring is correct. If it is reversed, the air outlet will become the air inlet. Generally, a check valve will be installed at the outlet. At this time, the negative pressure will rise and the current will be overloaded;

2. The pressure of Roots blower is reflected by the air outlet resistance at the rear end. If the air outlet is open, the pressure gauge will not be able to display the pressure at this time, because there is no pressure in the pipeline, and the compressed air is completely exhausted. You can slowly reduce the outlet valve to observe whether the pressure of the pressure gauge has risen. The maximum pressure should not exceed the pressure marked on the equipment, Avoid motor overload;
3. If the direction of the blower equipment is normal, the output pressure cannot meet the use requirements, and the motor has been overloaded, then it can be determined that the motor is small and the power is insufficient, and it needs to be added to the motor power to increase the higher pressure. Under normal conditions, as long as the quality of the fan is normal, it will not fail.
The pressure of Roots blower is the pressure of the front pipe. The value of the back pressure, which is often referred to, is also this value. Therefore, if there is a problem with the pressure, there is a problem with the front pipe.
What if the pressure is not enough? The problem cannot be solved by replacing roots blower. The roots blower in use shows insufficient pressure, so the pipeline must be checked to avoid pressure relief.
Under the rated pressure, Roots blower can operate normally, but if it exceeds the rated pressure, we need to check. This phenomenon also occurs when the pressure is insufficient when the model is small. When we install the fan, we find that the pressure is not enough, which means that the model is small and cannot reach the rated pressure, At this time, the fan is still in the working state of overpressure, which is dangerous.
