Introduction:
G type single screw pump is a kind of method of rotary displacement pump, the main working parts are eccentric screw (rotor) and fixed bush (stator), due to special geometric shapes, the stator, respectively to form a number of separate sealed vessel, rotor, will each medium continuously seal cavity, uniform, constant volume from the suction end to the extrusion end. Because of these characteristics, a single screw pump is particularly suitable for the following working conditions: 1, transport of high viscosity medium; 2, conveying medium containing solid particles or fibers; 3, continuous, stable pressure, periodic pressure fluctuation; 4, require small agitation, do not damage the inherent structure of the conveying medium; 5. Low noise.
Performance Range:
Flow: 0.8 - 150 m3/h
Size.: DN25-DN250 mm
Motor power: 0.75 ~ 90 kw
Applications:
Single screw pump as a universal pump, the flow can be adjusted according to the requirements by changing the speed, the running speed can be high or low, the export pressure can increase with the increase of the pump series, each increasing level, the pressure increases 0.6Mpa, widely used in the following range and industry.
- environmental protection: industrial sewage, domestic sewage, containing solid particles and short fiber sludge, especially suitable for oil-water separator, plate frame filter press and other equipment;
- shipbuilding industry: wheel bottom cleaning, oil and water, oil slag, oil sewage and other media transport;
- Petroleum industry: transportation of crude oil, crude oil and water mixture, coalfield gas and water mixture, injection of polymers into the formation, etc., thus reducing the cost of mechanical oil recovery, coalfield gas extraction, increased oil recovery;
- medicine, daily chemical: all kinds of viscous slurry, emulsion, all kinds of ointment cosmetics delivery;
- food canning industry: all kinds of viscous starch, edible oil, honey, syrup, fruit pulp, cream, fishy meat and the transport of its scraps;
- brewing industry: all kinds of fermentation viscous slurry, fermented lees. Residue of food products, various sauces, pulps and mucus containing lumpy solid matter, etc.
- construction industry: cement mortar, lime slurry, coating and other paste spraying and transportation;
- mining industry: the underground water and sewage slurry containing solid particles in the mine is discharged to the ground;
- chemical industry: all kinds of suspension, grease, all kinds of colloid slurry, all kinds of adhesive;
- printing, paper industry: high viscosity ink, WALLPAPER PVC polymer plastic and various concentrations of pulp, short fiber pulp conveying;
- industrial boilers, power plants: coal water slurry is transported.
