Screw pump application characteristics and reasonable selection method Screw pump because of its variable transport, self-priming ability, reversible, can transport solid particles containing liquid characteristics, in the sewage treatment plant, widely used in the transmission of water, wet Sludge and flocculant liquid. Screw pump selection should follow the pavilion package kits in ghana principle of economic, reasonable and reliable. If the design selection in terms of ill-considered, will give the future use, management, maintenance trouble, so the choice of a production according to the actual needs of a reasonable and reliable screw pump can ensure the smooth progress of production

but also reduce the cost of repair The Screw pump speed selection screw flow and linear relationship, relative to the low speed of the screw pump, high speed screw pump although can increase the flow and head, but the power increased significantly, high speed to accelerate the rotor and deck wpc dealers or manufacture Europe and the Middle East stator Of the wear and tear, must make the screw pump premature failure, and high-speed screw pump rotor length is very short, easy to wear, thus shortening the service life of the screw pump. Through the reducer or stepless speed control mechanism to reduce the speed

so that the speed of rotation to maintain the speed of 300 per minute to a more reasonable range, compared with the high-speed operation of the screw pump, the service life can be extended several times. The quality of the screw pump is now on the market more types of screw pump, relatively speaking, the import of screw pump design is reasonable, well material, but the price is higher, some of the service is not in place, parts prices are high, long order cycle, Affect inexpensive outdoor wicker seating sets Bergen the normal operation of production.
