Single screw pump selection considerations

Single-screw pump manufacturing method is relatively simple, so the use of such products relative to other pump equipment has a broader market, so the single-screw pump has a strong market competitiveness. So this special and useful single screw pump in the selection, what do we need to do? Single screw pump selection considerations what? Single screw pump selection considerations 1, the pressure of a single screw pump to determine; 2, single screw pump speed selection; 3, single screw pump bushing rubber material selection; 4, the choice of material combinations; Pump specifications are selected according to the nature of the fluid being transported and the pressure and pressure to determine the pump speed by the viscosity of the fluid and corrosive, as the main parameters to choose, to ensure reliable operation of the pump. Pump design speed for the transmission of water or water similar non-corrosive liquids allow the maximum speed, in actual use due to the nature of the media and life requirements are different, the selection should generally be lower than the design speed. For high viscosity and medium containing particles, the design speed of 1 / 2-1 / 3 or lower is generally used. Low speed is good for pump wear. However, the wear rate of the stator decreases after use. At this time, the speed can be properly increased , To compensate for the decline in traffic is also a policy. Transmission medium temperature should be -10 ℃ ~ 80 ℃ in special cases up to 120 ℃. The use of products can play its greatest functional effect, the product selection is very important, from the above study we can find that for the single-screw pump, in its product selection, not only to consider the various pump conditions, but also Considering the working environment of single screw pump, in short, the selection of single screw pump can not rely on sales staff a few simple introduction.
