Wastewater treatment engineering of screw pump selection

Screw pump because have self-priming capacity is strong, can variable transmission, reversible, conveying solid particles in the liquid characteristics, such as sewage treatment plants, widely used in conveying water, wet sludge and flocculant solution. Screw pump selection should follow the economic and reasonable and reliable principle. If the design selection thoughtle-ss, will give after the use of screw pump, management and maintenance trouble, so choose a according to actual needs, reasonable and reliable production of screw pump which can ensure production running smoothly, and can decrease the repair cost.
A screw pump, the speed of the selected
Screw pump flow and speed of a linear relationship between the relative to the low speed of screw pump, high speed of screw pump may increased flow and head, but power increased obviously
