Abstract
An efficient combined pump core comprises fixing ends, connecting shafts, connecting and fixing portions, connecting portions, blades, fixing pieces, a coupling piece and a main shaft. The blades are fixed to the cylindrical surfaces of the main shaft in an inclined mode. One ends of the outermost two main shafts are connected with the fixing portions. The connecting and fixing portions are connected with the fixing ends through the connecting shafts. The connecting portions are arranged at the other ends of the outermost two main shafts. The connecting portions are arranged at the two ends of the main shaft between the outermost two main shafts. A socket is formed in the center of each connecting portion. Limiting holes are formed in the side wall of each connecting portion. The two connecting portions are connected through the coupling piece. The connecting shafts at the two ends of a body of the coupling piece are inserted into the sockets of the connecting portions of the corresponding main shafts. The fixing pieces penetrate through the limiting holes and threaded positioning holes of the corresponding connecting portions. According to the pump core, multiple unit pumps are connected through the coupling piece, and therefore the requirements of different occasions can be met by assembling the pump core with any length as required.
