3G series three screw profile:
Three screw pump according to nationalstandard GB10887-89 design, manufacture. Three screw pump is apositive displacement pump rotor, is the use of the principle ofthe screw engagement, relying on the pump comprising a rotatingscrew engaged with each other, the transport medium enclosed inengagement cavity axially along the screw continuously pushed tothe uniform outlet, the system provides a stable pressure. Threescrew pump for conveying various non-corrosive oil and lubricatingoil and similar liquids. Transmission fluid viscosity range isgenerally 3.0 ~ 760mm2 / S (1.2 ~ 100 ° E), high viscosity mediumviscosity by heating after delivery. Its temperature generally doesnot exceed 350 ℃.
Three screw pump including 3G Universal,3GC ship type and special type. Three screw pump rotor type pumppit, because initiative driven screw screw with spiral grooves andtheir mutual engagement with the surface of the bushing with threeholes, was able to import and export of three screw-level dynamicseal is formed between the number of chambers These dynamic sealchamber will keep the liquid from the pump inlet to pump outletaxial movement, and to gradually boost the transmission fluid,thereby forming a continuous, smooth, axial movement of thehydraulic fluid.
Three screw pumps for a variety of body fluids containing solidparticles.
1, three screw conveyor continuously conveying medium is linear, nomixing, no pulse.
Two, three screw pump vibration and low noise.
3, three screw pump high pressure and high efficiency.
4, three screw pump, simple structure, easy disassembly.
5, three screw pump, small size, light weight.
6, three screw minor wear and long life.
7, three screw pumps are widely used in petroleum, chemical,metallurgy, machinery, electric power, machine tools, shipbuilding,glass, roads and other industries.
8, three screw pump for conveying fuel, lubricating oil, hydraulicoil, crude oil, asphalt and other similar liquid lubricating oils.
9, three screw pumps for lubrication in the industrial field, forthe hydraulic pump in the hydraulic system, in the fuel system fortransportation and booster pumps; in the oil system for thetransportation and pumps.
Flow range 0.2 ~ 600m3 / n maximum working pressure up to 6.3MPa.
Generally use mechanical seal.
Three screw through the jaw coupling driven by electric motors.Overhang from the spindle to the pump, the clockwise rotation.
