Three Screw Pump Lubricating Oil Transfer Pump 80 Degrees Celsius
Three screw pump according to national standard GB10887-89 design,
manufacture. Three screw pump is a positive displacement pump
rotor, is the use of the principle of the screw engagement, relying
on the pump comprising a rotating screw engaged with each other,
the transport medium enclosed in engagement cavity axially along
the screw continuously pushed to the uniform outlet, the system
provides a stable pressure. Three screw pump for conveying various
non-corrosive oil and lubricating oil and similar liquids.
Transmission fluid viscosity range is generally 3.0 ~ 760mm2 / S
(1.2 ~ 100 ° E), high viscosity medium viscosity by heating after
delivery. Its temperature generally does not exceed 350 ℃.
Three screw pump including 3G Universal, 3GC ship type and special
type. Three screw pump rotor type pump pit, because initiative
driven screw screw with spiral grooves and their mutual engagement
with the surface of the bushing with three holes, was able to
import and export of three screw-level dynamic seal is formed
between the number of chambers These dynamic seal chamber will keep
the liquid from the pump inlet to pump outlet axial movement, and
to gradually boost the transmission fluid, thereby forming a
continuous, smooth, axial movement of the hydraulic fluid.
Three screw pumps for a variety of body fluids containing solid
1, three screw conveyor continuously conveying medium is linear, no
mixing, no pulse.
2, 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, hydraulic
oil, crude oil, asphalt and other similar liquid lubricating oils.
9, three screw pumps for lubrication in the industrial field, for
the hydraulic pump in the hydraulic system, in the fuel system for
transportation and booster pumps; in the oil system for the
transportation 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.
