Description

Novel water pump

Technical Field

The utility model relates to a water pump especially relates to a novel water pump.

Background

The water pumps are divided into a plurality of types according to different structural principles, wherein the centrifugal pump is most commonly used and is designed according to the centrifugal principle, and impeller blades rotating at high speed drive water to rotate and throw the water out, so that the purpose of conveying is achieved. When the centrifugal pump operates, a motor of the centrifugal pump can generate a large amount of heat, if the heat is not dissipated in time, the motor can be accelerated to age and even be burnt. The existing heat dissipation structure usually adopts the mode that water is led from a water outlet and reaches the water inlet through the external circulation of the motor, and the motor is cooled by water, but the technical means has certain influence on the working efficiency of the centrifugal pump due to the reverse flow.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a novel water pump.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel water pump includes the pump body, motor, base, venturi, cooling tube, the pump body passes through the coupling joint the motor, just the pump body, motor all install in the base, venturi set up in the delivery port of the pump body, cooling tube one end is connected the water inlet of the pump body, the other end is connected venturi's negative pressure port, the cooling tube cover with the motor.

In the preferred embodiment of the present invention, the cooling pipe is arranged in an S-shape and wraps up on the outer wall of the motor.

In a preferred embodiment of the present invention, the cooling pipe is made of copper.

Compared with the prior art, the utility model provides a pair of novel water pump's beneficial effect is: the utility model relates to an ingenious, through to venturi's application, from the water inlet diversion to the motor cooling, to the delivery port confluence again, complied with the liquid flow direction, both guaranteed the normal work of motor, reduced the influence to efficiency again.
