The main sealing oil pump KG70KZ/7.5F4 is formed by the meshing of the spiral grooves on the main screw and the driven screw, as well as their matching with the inner surface of the three holes of the liner, to form several stages of dynamic sealing chambers between the inlet and outlet of the pump. These dynamic sealing chambers continuously move the liquid from the inlet axial direction of the pump to the outlet, and gradually increase the pressure of the transported liquid. Thus forming a continuous, stable, and axially moving pressure liquid. When the active screw rotates, it drives the driven screw that meshes with it to rotate together, and the meshing space volume of the screw at one end of the suction chamber gradually increases, while the pressure decreases.
The main sealing oil pump KG70KZ/7.5F4 has a simple and compact structure, and the pump core assembly adopts a modular structure that can be taken out as a whole, making it easy to maintain and repair; The mechanical sealing effect is good, ensuring no leakage.
