Kind Code:
A1
Abstract:
Disclosed is a jet water pump, comprising a pump body (1) provided with a water inlet (2) and a water outlet (3), wherein a water suction chamber (4) in communication with the water inlet (2), an impeller chamber (5) used for placing an impeller, and a high-pressure chamber (6) in communication with the impeller chamber (5) and the water outlet (3), respectively are provided inside the pump body (1), the water suction chamber (4) and the impeller chamber (5) are in communication by means of a diffusion channel (7), and the high-pressure chamber (6) and the water suction chamber (4) are in communication by means of a nozzle channel (8); and a flow stop mechanism is further provided, and same stops or enables the flow of a liquid in the nozzle channel (8). The flow stop mechanism is used for controlling the liquid in the nozzle channel (8) to flow, and when the pump body (1) completes self-suction and can work normally, the flow stop mechanism stops the flow of the liquid in the nozzle channel (8), such that a liquid in the high-pressure chamber (6) is prevented from flowing into the water suction chamber (4) to cause pressure relief, and a water flow discharged from the water outlet (3) can achieve the maximum hydraulic pressure.
