There are two transmission modes of Roots blower: direct connection and belt connection. Belt transmission is usually used, because the rotation speed of the fan and the motor of the direct connection roots blower are synchronous, while the rotation speed of the ordinary 4-stage motor is 1470 rpm. The cost of selecting other stages of motor is high. Therefore, the 4-stage motor is generally selected, and the belt transmission mode is economical and durable.
The use of V-belt drive is faced with this problem. How to calculate the speed of Roots blower is different from that of motor? It can be calculated with the following formula: motor speed * motor speed = fan speed * fan speed.
Through this formula, it is not difficult to see that as long as the size of the belt pulley of the roots blower is constant, and the speed of the roots blower can be checked from the manual according to the requirements of the flow and pressure parameters, the speed of the roots blower is also fixed, and the speed of the motor is also constant, it is easy to calculate the size of the motor pulley.
Tighten the nuts and adjusting screws for locking the three blade roots blower. Reduce the inlet temperature and outlet pressure. In some cases, the three blade roots blower has been used for a long time and occasionally makes a squeal, which may be due to the loose belt, unstable rotation speed of the three blade roots blower, fast speed and slow speed, and the gear is easy to make a squeal when the rotation speed is unstable.
To reduce the outlet of the fan, not at the outlet of the fan, it should be reduced at the outlet of the pipe, which will also increase the pressure of the fan, which also needs to cooperate with the current value of the motor, and can not be blindly increased or decreased.
The performance of the fan directly affects the quality and energy consumption of the sewage we treat. Low pressure three leaf roots blower is also called low pressure three leaf roots blower. High pressure three leaf roots blower is different from ordinary centrifugal roots blower in sewage treatment. Not clearing is a very dangerous mistake. The direction of rotation is from the side of the pulley to the left.
羅茨風機的轉速高低判斷標準要看羅茨風機具體機型而定，小風機可以轉速高一點，主要是源自羅茨風機生產加工制造時動平衡測試儀的精 密度，精 密度越高轉速可以越大，不過目前動平衡測試儀精 密度比較有限，所有大的羅茨風機轉速就要低一點，小的羅茨風機就可以轉速高一點。選羅茨風機的時候，建議選擇中低轉速，防止出現高轉速，這樣才能是羅茨風機的使用壽命延長。
The criterion for judging the speed of Roots blower depends on the specific model of Roots blower. The small blower can rotate a little higher, which is mainly due to the precision of the dynamic balance tester during the production, processing and manufacturing of Roots blower. The higher the precision, the greater the speed. However, the precision of the dynamic balance tester is relatively limited at present, and the speed of all large roots blowers is lower, A small roots blower can speed up a bit. When selecting roots blower, it is recommended to select medium and low speed to prevent high speed, so as to prolong the service life of Roots blower.
