A brief overview of sludge screw pump working principle and characteristics

Sludge screw pump is a single screw pump, its main working parts are eccentric screw spiral (called the rotor) and the inner surface of the double helical screw bush (called stator). Its working principle is that when the motor drives the pump shaft to rotate, the screw rotates on its own axis on the one hand, and on the other hand, it rolls along the inner surface of the liner to form a sealed chamber of the pump. Each revolution of the screw, the liquid in the sealed cavity is pushed forward by one pitch. As the screw rotates continuously, the liquid spirally presses from one sealed cavity to the other sealed cavity, and finally the pump body is extruded. At the same time it has many advantages over some other centrifugal pumps in many respects. 1, Compared with other rotary pumps, it is less sensitive to the entering gas and dirt. 2, solid structure, easy installation and maintenance. 3, uniform and continuous flow, small vibration, low noise. 4, because of legislation Shanghai sludge screw pump rotary inertial force is low, it can use a high speed. 5, good inhalation, self-priming capability. 6, transport a wide range of liquid types and viscosity. 7, a wide range of pressure and flow. The pressure is about 3.4-340 kgf / cm 2, and the flow rate can reach 18600 cm 3 / min.
