How can the pressure resistance of a Roots blower be improved?
Release date:

The Roots blower is a positive-displacement rotary blower; therefore, the pressure in the upstream pipe is the pressure of the Roots blower itself, and the pressure gauge indicates the pressure in the upstream pipe. Generally speaking, the "pressure" referred to here actually refers to the Roots blower's compression capability—meaning it can withstand extremely high pressures but cannot handle pressures exceeding its rated value. If the Roots blower is reversed, it could cause the engine to burn out.
Roots blower Since it’s a positive-displacement rotary blower, the pressure in the front pipe is the same as the pressure of the Roots blower; the pressure gauge indicates the pressure in the front pipe. In general, the “pressure” referred to here actually refers to the compression capability of the Roots blower—meaning it can withstand extremely high pressures but cannot handle pressures exceeding its rated value. If the Roots blower is reversed, it could cause the engine to burn out.
In the selection of Roots blowers, the pressure referred to is the outlet pressure. First, since Roots blowers are positive-displacement machines, they do not generate pressure on their own. So how does the pressure in a Roots blower arise? In fact, the "Roots blower pressure" refers to the ability to overcome the pressure in the upstream pipeline. This pressure depends on both the outlet pipeline pressure and atmospheric pressure. Therefore, when selecting a Roots blower, it’s crucial to pay attention to the selected pressure range. If the actual pressure exceeds the rated pressure, Roots blower It will be in an overpressure state and may burn out the motor. If the pressure is insufficient, it could result in failure to achieve the desired performance. So how can we improve the pressure resistance of Roots blowers?
1. Replacing the motor is a direct and effective method recommended by the manufacturer. By replacing the motor with one of greater power while keeping the base unit unchanged, the compression capability of the Roots blower can be directly and effectively enhanced. Moreover, this approach often serves as an efficient solution without altering the base unit of the Roots blower itself.
2. Under specific pressure conditions, if the blower’s maximum parameters have already been exceeded, simply replace it with a larger-sized unit. Roots blower Resisting excessive pipeline pressure is also a safe approach.
3. Can replacing the pulley increase the working pressure? Replacing the pulley is a teaching method used to modify the operating speed of a Roots blower; therefore, it has little effect on the pressure.
4. Roots blower Excessive pressure and insufficient pressure are two different issues. How can we improve pressure? If the pressure is too high, there’s no need to replace the Roots blower; instead, simply installing a branch pipe on the pipeline to reduce the pipeline’s pressure would suffice. However, this approach has a drawback: it doesn’t allow for energy savings.
