Structural Principle: The SNH210R54E6.7W21 three - screw pump consists of one driving screw and two driven screws that are meshed with each other and fixed in the bushing. The screw profile is composed of double - head cycloid and arc tooth shape. The screw pair and the bushing are installed in the pump body. When the driving screw rotates driven by the prime mover, a sealed cavity is formed by the driving and driven screws under a certain length of the meshing helical surface. The driven screw is pushed to rotate by the pressure difference on both sides of the helical surface of the conveyed liquid medium. At this time, the conveyed liquid enters the pump suction and then axially and continuously enters the sealed cavity. It smoothly and undisturbedly reaches the discharge cavity from the pump suction cavity, thus achieving the function of transporting the liquid medium.
Application Scenarios
Heating Equipment: It can be used as a fuel supply and transfer pump, and a boiler ignition pump in heating equipment.
Industrial Production: In industrial production, it serves as a hydraulic pump, lubricating pump, light fuel pump, and transfer pump. It is widely used in supporting facilities such as the lubrication and hydraulic industry, high - and low - pressure thin - oil lubrication stations, thin - oil lubrication devices, and filtration devices.
