ALLWEILER Screw pump It is widely used and plays an important role in sewage treatment. It can transport wet sludge and flocculant materials. The selection of screw pump should be economical, reasonable, safe and reliable, and it is the most important to meet the requirements of use.

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 material of transmission components and long rated life shall be selected. The rotating speed of screw pump has great influence on the operating efficiency and life. 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, Then the service life of the screw pump is shortened. The speed is reduced by decelerating the organization, so that its speed is kept within a reasonable range of less than 300 revolutions per minute. Compared with the high-speed screw pump, its service life can be extended several times.

During the operation of the screw pump, it shall be noted that no sundries can enter the pump body to avoid damaging the stator of the screw pump. 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 avoid blocking. IMO

The equipment in the screw pump will be shut down when the material is cut off, so as to avoid running under the condition of material cut off, causing wear and burning the equipment due to high temperature. In addition, stable outlet pressure shall be maintained during operation to avoid overloading and equipment damage.
