First, the use of SPF three-screw pump

Suitable for thermal power plant, glass cement, asphalt mixing station, building material factory, ship, chemical industry, pharmaceutical factory, highway asphalt mixing station, steel plant blast furnace, high-pressure steam boiler, oil-fired boiler, circulating fluidized bed boiler, marine boiler, ship industry, Diesel engine, turbine boiler and other fuel delivery systems or burner fuel delivery fuel injection applications; Mainly conveys fuel oil, diesel oil, heavy oil, lubricating oil, hydraulic oil, marine diesel oil, gasoline (MDO,MGO), heavy duty fuel HFO, vehicle fuel, bio-oil, etc., or other lubricating liquids, The medium shall not contain any abrasive particles and corrosive substances to pump materials. S PF series three-screw pumps are widely used in oil transportation and injection, as well as in industrial pipeline transportation as fuel oil transport and regulation pumps. And more for all kinds of asphalt mixing plant and asphalt mixing plant burner and medium and small gear box gear reducer hydraulic lubrication equipment. Can provide complete supply of motor screw pump assembly, with oil absorption pipes and support, as well as complete test reports, can provide pressure relief valve sets and other supporting accessories;

II. Main areas of application

SPF series three-screw pump is used as fuel pump in burner fuel system for transportation, injection, pressurization and fuel furnace, as booster pump, fuel injection pump and diesel ignition pump in oil transmission system. It can be used as lubricating oil pump in all industrial fields, hydraulic pump in all kinds of hydraulic transmission.

III. Structure

The SPF pump is a self-priming three-screw pump with built-in bearing. The screw is treated by nitridation and hardened on the surface. The surface of the screw pump is specially treated and the hardness is 63HRC. The pump is operated in a replaceable bushing. The main rod adopts hydraulic balance, the axial force of the rod is supported on the back cover and rotates by hydraulic force, so the screw face only transmits hydraulic torque, does not bear force, and has no wear. For all transmission parts, it is lubricated by the conveying medium. The radial direction of the main rod is located by the balance piston, and with the help of the clearance between the balance piston and the shaft sleeve, the high pressure cavity and the seal cavity are separated. There are mechanical seals in the sealing cavity, oil return holes and pumps in the cavity. The suction cavity is connected to each other and is therefore not affected by the discharge pressure. All sliding parts are lubricated by medium. Shaft seal is mechanical seal, no leakage and no maintenance. The sealing chamber and the suction chamber are connected by an internal loop. The output pressure on the shaft seal is independent and only produces absorption pressure. Pump and motor are connected by bracket. When the spiral rotates, the three spirals of the seal chamber perform a complete continuous axial motion. The rotation of the spiral does not cause vibration. Outside the extrusion, the capacity of the seal chamber remains unchanged. The stability of structure design and operation ensures low noise and no pulsation of screw pump operation. The pump is connected and driven by a bracket, coupling, and motor. Type 20, or wall mounted (for example, Type 40).
