What is a screw pump? How does the screw pump work?
A: Screw pump is also a positive displacement pump, also known as screw oil pump; Divided into three screw, twin screw and single screw; It is by a few intermeshing screw volume changes to transport liquid volumetric rotor pump, single screw, twin screw, three screw, etc., three screw pump in my plant more applications.
Working principle: the actual screw pump is the main, driven screw and pump shell surrounded by the screw groove space formed by the closed volume. The middle for the active screw drive on both sides of the driven screw, the main screw for the right convex screw, and the driven screw for the left concave screw, when the motor drive the main screw rotation, three meshing screw groove space of the liquid forward movement, so as to constantly the liquid suction and discharge.
