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.
