一 Summarize
G series single screw pumps are new mesh gyration type cubage
pump which have advantages of high effiency, strong self-suction
ability, wide using range and it can transport variety of mediums
that are difficult to transport. So the single screw pump is
named Omnipotence pump.It can transport the liquids that is
neutral or corrosive, clean or sharp liquid, the liquid contained
gas or the liquid that is easy to produce bubble, the liquid
with high or low viscosity and including the liquid contained
fibre and solid matter.
二 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 .

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,

| The
data can reached when clean water medium( or as mucous membrane)
is on the 20℃ standard atmosphere condition without side current.
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.
