Corrosion resistant screw pump

Stainless steel single screw pump is a single screw transport pump, its main working parts are the eccentric helix screw (called rotor) and the inner surface of the double helix screw bushing (called stator). The working principle is that when the motor drives the pump shaft to rotate, the screw on the one hand rotates around its own axis, on the other hand, it rolls along the inner surface of the bushing, so as to form the seal chamber of the pump. Each time the screw turns, the liquid in the sealing chamber advances a pitch, and with the continuous rotation of the screw, the liquid spirals from one sealing chamber to another sealing chamber, and finally extrudes the pump body. Screw pump is a new type of liquid conveying machinery, with simple structure, safe and reliable work, easy to use and maintenance, liquid continuous uniform, stable pressure and so on. The utility model relates to a pump that uses the rotation of a screw to suck and drain liquids, which is best suited to suck and drain viscous liquids.

The LG screw pump uses the rotation of the screw to suck and drain the liquid. Due to the mutual engagement of the screws and the close coordination between the screws and the inner wall of the liner cylinder, between the suction inlet and the discharge outlet of the pump, it will be separated into one or more sealed Spaces. With the rotation and engagement of the screw, these sealed Spaces are constantly formed at the suction end of the pump, the liquid in the suction chamber is sealed into it, and the self-suction chamber is continuously pushed along the screw axis to the discharge end, and the liquid in the enclosed space is continuously discharged, just like a nut is constantly pushed forward when the screw is rotated, which is the stainless steel single-screw pump. After the liquid is sucked into the screw thread and the sealing space surrounded by the pump shell, when the active screw rotation, the screw pump sealing volume under the extrusion of the screw pump pressure, and along the axial movement. Because the screw is rotating at a constant speed, the liquid flow rate is also uniform.
