Can the pressure of Roots blower be adjusted?

Can the pressure of Roots blower be adjusted? The pressure of Roots blower refers to its load pressure capacity, not the pressure that can be generated by Roots blower. Roots blower does not generate pressure itself. When we use Roots blower to transport air, the front pipe will carry pressure. In order to transport air, the blower needs to overcome this pressure to transport air.

When we select the type of Roots blower, the pressure of the blower may be small or large, which requires us to adjust the pressure of the blower. Here's how to adjust the pressure of the blower:

1. Fan overpressure, larger fan required

In the face of overpressure, in order to reduce the pressure of the fan, we can reduce the pressure by increasing the exhaust port, but increasing the exhaust port will reduce the air volume. If our air volume is just enough, this method cannot be used.

The common method is to replace a larger motor. For example, we used a 15kw motor before. We can replace a 22kw motor to meet the pressure demand.

2. Fan pressure cannot reach

When the pressure of our fan cannot reach the limit, it means that the fan is not working at full load. At this time, the main impact on us is the loss of electric energy. If the pressure of the fan is too high, it will cause an increase in energy consumption. If we need to adjust the pressure, we can replace a smaller motor. According to our understanding, In this case, few customers will take the initiative to replace small models of motors, except for some large models of Roots blowers, which consume a lot of power. In this case, the company will generally carry out energy-saving transformation.

3. About air volume&speed

The rotation speed of the fan directly affects the air volume. Some customers need to speed the fan on the site. The speed adjustment needs to be controlled by a frequency conversion motor and a frequency converter. Ruituo Blower also suggests that when purchasing the fan, the configuration of the frequency converter and frequency conversion motor should be considered for the working conditions where the air volume needs to be controlled.
