Abstract

The invention discloses a multifunctional submersible pump. The pump comprises a pump body, a first pump cavity, a second pump cavity and a third pump cavity are formed in the left side of the pump body, a first rotating shaft, a second rotating shaft and a third rotating shaft are rotationally connected into the pump body, a first impeller is fixedly arranged on the first rotating shaft, a second impeller is fixedly arranged on the second rotating shaft, and a third impeller is fixedly arranged on the third rotating shaft; a middle plate is arranged on the left side of the pump body, and a first inlet hole, a second inlet hole and a third inlet hole are formed in the middle plate; a first outlet hole, a second outlet hole and a third outlet hole are formed in the pump body; a left pump cover is fixedly arranged on the left side of the middle plate, a liquid outlet cavity and a liquid inlet cavity are formed in the left pump cover, and a liquid inlet hole and a liquid outlet hole are formed in the outer side of the left pump cover; and a switching assembly is arranged in the liquid outlet cavity. The multifunctional submersible pump is simple in structure, variable in flow and capable of being switched between a low-pressure working state and a high-pressure working state.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a multifunctional submersible pump. Background technique [0002] At present, the widely used submersible pump is suitable for all walks of life because of its small size, light weight, and convenient installation. Submersible pumps are important equipment for deep well water extraction. When in use, the whole unit dives into the water and extracts groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape. A submersible pump is a drainage machine in which the pump body and the motor can be immersed in water. The traditional submersible pump consists of four parts: the pump body, the submersible motor (including cables), the water delivery pipe and the control switch. The submersible motor is located in the pump body, and the water delivery pipe and The water delivery...
