Based on the above purpose, the technical solution adopted by the utility model is a high-efficiency multifunctional water pump. The water pump is composed of a motor and a pump inside the housing, and the upper and lower ends of the housing are respectively equipped with a water outlet cover and a water inlet cover; the motor The shell is equipped with a shock-absorbing ring, and the motor shaft provided with the motor is provided with an intermediate support and a pump.

The pump is equipped with a deflector, an impeller, and a guide vane, and the motor shaft drives the impeller in the pump. An integrated sealing device is embedded in the axial inner side of the deflector, and the sealing device is composed of a sealing seat, a sealing ring and a sealing ring. The sealing ring is tightly fitted with the impeller ring; the pump is equipped with a water outlet cover, the water outlet cover is installed on the water outlet cover plate, and a check valve core is installed inside the water outlet top cover .

The beneficial effects of the utility model are:

1. The motor of the high-efficiency multi-functional water pump of the utility model adopts a water-cooled cooling method, and the heat generated by the motor is naturally cooled and taken away by the conveyed fluid, so as to ensure that the motor will not be burned due to overheating.

2. The high-efficiency multifunctional water pump of this utility model adopts a guide plate, impeller and guide vane installed in the pump. Since multiple impellers are used in series, the water pump has a high lift, and an integrated seal is embedded in the axial inner side of the guide plate. The sealing seat, sealing ring and sealing ring cover are tightly fitted with the impeller mouth ring to reduce leakage and improve pump efficiency. The service life and reliability of the machine are also greatly improved.

3. The high-efficiency multi-functional water pump of the utility model is a multi-purpose water pump. The motor and the pump are integrated in a sealed casing. The design is reasonable, the structure is unique, the application range is wide and the installation method is flexible. Used as an onshore centrifugal pump, submerged pumps and submerged pumps are replaced by submerged installations, onshore centrifugal pumps are replaced by onshore installations, horizontal centrifugal pumps are replaced by vertical installations, vertical pumps and pipeline pumps are replaced by vertical installations. different requirements.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1, a kind of high-efficiency multifunctional water pump is made of motor 15 and pump 16 arranged in the housing 14, and the upper and lower ends of the housing 14 are respectively equipped with a water outlet cover 10, a water inlet cover 10-1, and motor 15. The motor shaft 15 - 1 is sleeved with the intermediate bracket 4 and the pump 16 , and the motor shaft 15 - 1 drives the pump 16 .

The motor 15 includes a stator and a rotor. The stator part is composed of a motor stator 1, a number of guide plates 5, a number of guide vanes 7, a water outlet top cover 8, and a check valve core 9.
