Abstract

The invention discloses a double-suction double-shaft multi-stage axially split pump system. The system comprises a main power source, a main transmission shaft, a first primary water pump, a second primary water pump, at least one secondary main water pump, a transmission gear pair and at least one secondary main transmission shaft. The main power source provides power for the first primary waterpump and the second primary water pump through the main transmission shaft, the main power source provides power for the secondary main water pump through the main transmission shaft, the transmission gear pair and the secondary main transmission shaft, and the first primary water pump and the second primary water pump are connected with the secondary main water pump through an external connection pipeline. The double-suction double-shaft multi-stage axially split pump system is simple in structure and convenient to use, rigidity transmission and variation transmission ratio are achieved, theproblem that a traditional water pump is serious in cavitation is solved, a main output stage hydraulic model can adopt the extremely-high-efficiency hydraulic model due to the negative pressure of the suction stage, the output energy consumption is greatly reduced, and the energy saving effect is achieved.

Description

technical field [0001] The invention relates to the field of split pumps, in particular to a double-suction, double-shaft and multi-stage split pump system. Background technique [0002] Domestically and internationally, several pumps are used to operate in series to achieve high-lift delivery at low speed. This mode of operation will cause a loss of at least 20%, resulting in a large amount of energy consumption. If water is taken from rivers and ditches for irrigation or the water temperature is high, the performance requirements for the NPSH of the water pump are high, and the existing water pumps and single pumps cannot meet the requirements, so a front pump or a front negative pressure device needs to be added. Reliability and convenience are greatly weakened like this. [0003] In order to solve the above problems, it is urgent to invent a double-suction double-shaft multi-stage split pump system to solve the problems of serious cavitation and high energy consumption...
