When the multi-stage pipeline pump motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller is thrown around the impeller along the flow path between the blades from the center of the impeller due to the centrifugal force. Since the liquid is affected by the blades, The pressure and velocity are simultaneously increased and directed through the flow passages of the guide shell to the secondary impellers so that all of the impellers and guide shells flow sequentially one after the other to further increase the pressure energy of the liquid. After each impeller step by step, you get a certain lift.
Multi-stage pipeline pump is pressurized transmission pipeline to solve the pipe pressure is too low and developed a new pump, horizontal centrifugal pump than the current application has great advantages. Due to the advanced mechanical seal, the main shaft of the motor is directly mounted on the impeller. Therefore, the utility model has the advantages of high efficiency, low power consumption, compact structure, small size, light weight and convenient decoration. The utility model can be used according to the requirement of the head and the flow and the series connection.
