sludge screw pump is a single-screw transport pump sludge screw pump is the single screw pump in the application of sewage sludge, sludge using eccentric screw of the single screw pump rotation in the double spiral bushing, sewage sludge along the spiral groove by suction to discharge, this is the work principle of screw pump sludge. Screw pump is a single-screw transport sludge pump, screw pump sludge is the main working parts of eccentric screw helix ( According to the rotor) And the inner surface is on the surface of the double spiral screw bushing ( According to the stator) 。 Sludge screw pump working principle is when the motor drives the pump shaft rotation, screw around the axis of rotation itself on the one hand, on the other hand it along the bushing inside surface rolling, then form the pump seal chamber. Screw each week, liquid sealed cavity forward a pitch, with continuous rotation of the screw, liquid spiral way from a sealed cavity pressure to the other a sealed cavity, finally out of the pump body. Sludge screw pump is a new type of fluid conveying machinery, has a simple structure, safe and reliable work, convenient operation and maintenance, the fluid continuous uniform, stable pressure, etc. Sludge screw pump is a kind of use of the rotation of the screw to absorb liquid pump, screw pump is the most suitable for sludge absorption viscous liquid. Screw pump is single screw pump has the advantages of screw pump common sludge. Sludge screw pump is suitable for transmission of low viscosity medium such as water, is especially suitable for conveying suspending liquid containing solid particles or short fibers, and very high viscosity medium. 1) Wide range of pressure and flow. Pressure around 3. 4 - 340 kilograms force/cm 2, flow rate of up to 18600 cubic cm/min; 2) Wide range of delivery and type of liquid viscosity; 3) Because of lower rotary inertia force component of sludge in the screw pump, screw pump sludge property may be using a high speed; 4) Aspiration can good, self-priming ability; 5) Flow uniformly continuous, little vibration, low noise; 6) Compared with other rotary pump, less sensitive to enter gas and dirt; 7) Solid structure, installation and maintenance easy. The use of sludge screw pump: 1, prepare necessary wrench and tools. 2, check the stand, there is no lubricating oil in the bearing and oil chamber. 3, check the flesh hollow shaft seal are appropriate degree, packing gland may not be too tightly on the packing and the drip leakage is allowed. 4, turn the coupling by hand or pipe wrench, pay attention to the sludge screw pump noise presence of foreign bodies in the pump body collision and stuck phenomenon, if the rear can drive should be removed. 5, the material liquid filled with sludge pump cavity, pump running in friction, so as not to smash bushing. 6, fully open out the liquid pipe gate valves. 7, drive motor. Sludge screw pump is the use of screw rotary to absorb liquid. The middle screw to active screw, the prime mover, on both sides of the screw is driven screw, with the active screw do reverse rotation. Lord, driven screw thread are double thread. Due to the mutual engagement of each screw and screw and the close coordination of the liner wall, between the inlet and the outlet of the sludge screw pump, can be divided into one or more of the sealed space. With the rotation of the screw and meshing, the sealed space form in sludge screw pump suction side constantly, the liquid from the suction chamber seal in among them, and the suction chamber along the screw axial continuously goes on to the discharge end, will be closed in the space of the liquid discharge, like a nut in screw rotation being constantly move forward, this is the basic work principle of screw water pump sludge.

Nowadays, it is very common for us to utilise in pool cover drain pump. And the quality of is decisive to production efficiency.
