IMO screw pump It is widely used and plays an important role in sewage treatment. It can transport wet sludge and flocculant materials. Screw pump The most important thing is to make the choice of "" economic, reasonable, safe and reliable, and meet the requirements of application.

The quality is very important for the selection of screw pump in sewage treatment. Considering the cost performance ratio, the equipment with low speed, long lead, good materials for transmission components and long service life shall be selected. The rotational speed, operating power and life of screw pump have great influence. The flow of the screw pump is linear with the speed. Compared with the low speed screw pump, the high speed screw pump can add flow and head, but its power is significantly increased. Rotating speed speeds up the wear between the rotor and stator, which must make the screw pump fail prematurely. The high-speed screw pump rotor is very short and easy to wear, and then shortens the service life of the screw pump The speed is reduced by the speed reducer to keep the speed below 300 revolutions per minute. Compared with the high-speed screw pump, its service life can be extended several times.

　　 ALLWEILER screw pump During the operation of the screw pump, it shall be noted that no sundries can enter the pump body to avoid damaging the screw pump stator. In order to prevent sundries from entering, the equipment grid equipment or filter screen can prevent sundries from entering the screw pump, but the grid should be timely sorted to prevent blocking.

In the screw pump, it is best to stop the equipment when the material is cut off. Once the material is cut off, the equipment will be stopped to prevent the equipment from running under the condition of material cut off, causing wear and burning due to high temperature. In addition, constant outlet pressure shall be maintained during operation to prevent overloading and equipment damage.
