The performance parameter range and application situation of screw pump only refers to the general situation of a screw pump, not including all kinds of screw pump. This paper introduces the application scope of screw pump briefly

Screw pump performance parameter values are not absolute double screw pump maximum output pressure is 8 (20) MPa is a 0.A.IIbIK called B type double screw pump, A type double screw pump maximum discharge pressure is only 1.6MPa. 3400m2/h for maximum flow refers to the current situation it is symmetric type cycloid spiral surface, we call the N type double screw pump in this case the discharge pressure is low, if you need to actually develop a larger flow of products; this type of double screw pump in some media, some flow value and some structure, the current maximum discharge pressure is 8Mpa or even taller.

Gas-liquid only suitable for N type double screw pump, single screw pump can not be used for other types of gas-liquid. The non lubricating fluids are only applicable to the N shape and square tooth shaped double screw pump. Although the three screw pump for high pressure category of the axial force balance is difficult to apply only to a small stream the amount of working condition; although the three screw pump can adopt double suction structure in large flow, so the automatic balance axial force, the length of the screw is subject to various factors such as deflection and intensity limit so still can only be used in the condition of low pressure high flow three screw pump can also consider product size factors such as flow actually greater than 200m3/h with very little.

Three screw pump applications refers only to the lubrication and low run along the clean liquid, actually take some measures in structure and material and other aspects have also used to transport the impurity asphalt, only the discharge pressure is very low, short service life. With the development of science and technology, special material new successful research other factors now abroad has also been successfully developed three screw pump can transport water, sea water and low viscosity without lubrication, in spite of their discharge when the pressure increases, volumetric efficiency decreased rapidly, at present also can only be used for low discharge pressure conditions, the service life is short and the actual use is very few, but this is after all a breakthrough results.

Screw pump on the introduction of so many, I hope to be helpful to the home
