Roots blower There are two transmission modes: direct connection and belt connection. Belt transmission is usually used. Because the speed of the direct connected fan is synchronous with the speed of the motor, while the speed of the ordinary 4-stage motor is 1470 revolutions. The cost of selecting other stages of motor is high, so people generally choose 4-stage motor. Belt transmission is economical and durable.

V-belt transmission is faced with this problem. How to calculate the difference between the rotational speed of Roots blower and that of motor? The following formula can be used to calculate: motor speed * motor speed=fan speed * fan speed

It is not difficult to see from this formula that as long as the size of the Roots blower pulley is constant, and the rotation speed of the Roots blower can be found from the instructions through the requirements of the flow and pressure parameters, the rotation speed of the Roots blower is also fixed, and the rotation speed of the motor is also constant, then it is easy to calculate the size of the motor pulley.

The rotating speed of Roots blower shall be reduced as far as possible when meeting the requirements of technical parameters of flow and pressure so as to extend the service life.
