Roots blower is a common environmental protection equipment in sewage treatment

Roots blower is an environmental protection equipment commonly used in sewage treatment, and three leaf roots blower is a fan commonly used in sewage treatment.

1、 Sewage treatment fan - Roots blower, if the load requires constant flow effect, roots blower will be used. Because Roots blower is a constant flow fan, the main working parameter is the air volume, and the output pressure changes with the change of pipe and load, and the air volume changes little. Roots blower is a high pressure fan. Roots blower is a positive displacement fan. The air volume conveyed is proportional to the number of revolutions, and the gas is conveyed from the suction side to the discharge side.

2、 Sewage treatment fan centrifugal fan is used if the load requires constant pressure effect. Because the centrifugal fan is a constant pressure fan, the main working parameter is the air pressure, and the output air volume changes with the change of the pipeline and load, and the air pressure changes little. Centrifugal fan with low air pressure. The air compression process is usually carried out by several working impellers (or stages) under the action of centrifugal force. Centrifugal fan belongs to square torque characteristic, while Roots fan basically belongs to constant torque characteristic.

3、 Sewage treatment fan - rotary fan. Roots blower generally has large air volume and pressure, and also has large noise. If the required air volume is relatively small and the requirements for noise are high, the rotary blower is selected. The rotary blower is also a constant flow fan, and the main working parameter is air volume, The output pressure changes with the change of pipeline and load, and the air volume changes little. The rotary fan is variable volume compression, and its main characteristics are: low speed, low noise, low vibration, high Efficiency, high energy saving.
