¶þ Work principle and features
The work principle of single screw pump is that the medium is transported from the suction side to press side by the seal room being come into between the rotator and stator continually and uniform speed and keep the cubage when the rotator of single screw turn around the inside the stator hole of double line screw.Because of the smart working principle, the single screw pump not only has the general feature but also it has best remarkable advantages as follows :

1.It can transport high viscosity medium .Based on different size pumps, the highest viscosity of medium
is 370000 -200000 centipoise.

2.It can transport soild, sharp and fibre matter .The contain can reach 40% of the medium ,when the soild of the medium is the small powder, the contain can reach 70%, the max diameter of soild is allowed 2mm-40mm according to different size of the pump.
3.The liquid exported is contuine and uniform , pressure is reliable, small mix , not change the component to the senstive liquid.

4.The relationship between the rate of flow and rotate speed is simple direct tation.It can adjust the rate of flow by adjusting speed , equipped with speed-changed electric machinery, it is the variable pump .

5.The pressure can be automatic adjusted accrording to the resistance of export pipe.Between 0-36(kg/cm2)pressure, the customer is easy to reach the right pressure.This not only save energy but also avoid craft flow being effected caused by too high or low pressure.

6. Simple structure, small wear, convenient maintance .
Compared with other type pumps
Compared with centrifugal pump, it not need to install valve; however the rate of flow is reliable line flow.
Compared with plug pump , it has better self-suction ability , the height can reach 8.5 meter water column .
Compare with dissepiment pump, it can transport variety of mixture , the meduim contained soild or fibre ,also corrosive matter .
Compared with gear pump, it can export high viscosity matter.Different with plug
pump,dissepiment pump,gear pump,single screw pump can be used in filling medicament and measure .

Apply Range
G series single screw pumps can be classified as three kinds according to different materials:
1 Ordinary pump:
Main range : grease separate set transport pump, sewage deal set transport pump;spray set transport pump;incinerator transport pump;transport sewage ,dejecta ; transport lube,fuel,foliage oli ;transport aggradation paste and contain soild medium, oil , watermark physical geography prove drill transport nud ;new type wet spin paste asbestos plasm transport ;viscidity printing ink, argil,clay paste, pulp; and the pump that transport concreter,detonator, water-coal nud,,Kaolin and fibre liquid etc.

2 Food range :(adopt stainless steel and innocuity rubber material)
Main range : vintage, beer bud without attenuant ,beer barley ,milk powder, malted milk, amylum,tomato, ferment liquid ,sance, honey,chocolate admixture, milk, cream,cheese and meet nud , also can be applied in the field of pharmacy and toothpaste industry.
3 Chemical pump:(adopt stainless steel and corrosion resistant rubber material ) :
Main range : corrosive oil, chemical medium , paint , deep oil paint, cosmetic, ointment, soap, environment protection industrial department; is the ideal pump of pressure filter .

The performance parameter of frist -grade pump , the pressure and power of two, three, four,five ,six grade pimp is equal to two,three ,four,five , six times of the date of the form ,the rate of flow is same as the first grade pump.

Note:
1 To select the above pharameter for general mediums .
2 To high vsicoisty medium ,sgarp medium and medium contain much solid .Please select the rate of flow according to 1/2-1/5 of rotaty speed of the form, the rotaty speed and rate of flow is simple direct ration.i.e. if the rotate speed low down 1/2 ,the rate of flow also reduce 1/2
3 Being the speciality of single screw pump. For reach the ideal effection, the best effective way is that you need consulting with our experts, it can avoid wasting time and money .When you need the pump you¡¯d better tell us the rate of flow, pressure, medium and its feature meet your demand by letter or coming in advance .So that our expert can assitant you to select the best type pump.
