The sealing oil pump KG70KZ/7.5F4 is fluid conveying equipment with a unique spiral groove meshing technology as its core, widely used in various high temperature, high pressure, and high wear conditions. Its main function is to provide high-pressure and high-temperature sealing oil for the turbine shaft seal, ensuring the normal operation of the turbine and extending its service life. This article will provide a detailed introduction to the principle, structure, characteristics, and application of the sealing oil pump KG70KZ/7.5F4.

The working principle of the sealing oil pump KG70KZ/7.5F4 mainly depends on the meshing of the spiral grooves on the main screw and the driven screw, as well as their fit with the inner surface of the three holes of the liner. Between the inlet and outlet of the pump, several stages of dynamic sealing chambers are formed, which continuously move the liquid axially from the pump inlet to the pump outlet and gradually increase the pressure of the transported 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 parameters of the sealing oil pump KG70KZ/7.5F4 are:

Flow range: 0.5-2000 m2/h
