The diagonal flow pump water turbine is suitable for power stations with lower water heads and larger water head amplitude, and has higher comprehensive efficiency. In order to solve the problems, if the diagonal flow water turbine can be redesigned and improved, the diagonal flow water turbine becomes a diagonal flow water pump water turbine capable of meeting the bidirectional operation, and the diagonal flow water pump water turbine is in a good state in water pump working condition and water turbine working condition water flow state, but no related report is seen so far.
