Features and application fields of sludge screw pump

The sludge screw pump is a single screw pump. Its main working parts are the screw of eccentric helicoid (i.e. rotor) and the screw bushing (i.e. stator) with double helical surfaces on the inner surface. The sludge screw pump is a pump that uses the rotation of the screw to suction and discharge liquids, which is most suitable for suction and discharge of viscous liquids.

Working principle of sludge screw pump:

The sludge screw pump is a single screw transport pump. Its main working parts are the screw of eccentric helicoid (called rotor) and the screw bushing (called stator) with double helical surface on the inner surface. Its working principle is that when the motor drives the pump shaft to rotate, on the one hand, the screw rotates around its axis, on the other hand, it rolls along the inner surface of the bushing, thus forming a sealed chamber of the pump. Every time the screw rotates, the liquid in the seal cavity moves forward by a screw pitch. With the continuous rotation of the screw, the liquid is pressed from one seal cavity to another in a spiral way, and finally the pump body is extruded. Screw pump is a new type of liquid conveying machine, which has the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform liquid discharge, stable pressure, etc.

Features of sludge screw pump:

1. Stable flow: When the sludge screw pump delivers various liquids, the flow is stable, and the outlet pressure is not pulsating like the diaphragm pump.

2. Low noise and strong self-priming capacity: the sludge screw pump has low vibration and noise, and has self-priming function and good self-priming capacity.

3. Delivery of high viscosity medium: sludge screw pump can deliver liquid of high viscosity medium.

4. Simple structure: the structure of the sludge screw pump is relatively simple and compact, the screw pump occupies a small area, and its weight is relatively light

5. Long service life and convenient maintenance: it is characterized by stable working performance, long service life and convenient operation and maintenance of sludge screw pump.

Main purposes of sludge screw pump:

In addition to conveying various flowable media, the sludge screw pump can also transport highly viscous media, media containing hard suspended particles or solid particles, and media containing fibers. With good regulation performance, wide range, and high efficiency, it is widely used in environmental protection, ships, petroleum, medicine, daily chemicals, food, brewing, construction, mining, chemistry, printing, paper making, power plants, boilers and other industries.
