Water pump with good cooling effect

Abstract

The invention discloses a water pump with a good cooling effect. The water pump comprises a shell, a drive motor and a water suction pump. The drive motor and the water suction pump are fixedly arranged in the shell. The drive motor is in transmission connection with the water suction pump. The drive motor is composed of a motor body and an end cover. The motor body is fixedly connected with the end cover. An annular circulating water tank is fixedly arranged in the end cover. A detection contact is fixedly arranged at the top end of the water suction pump. A buzzer is fixedly arranged at the top end of the shell. The water pump is simple in structure, low in manufacturing cost and high in practicality. By means of the annular circulating water tank, the temperature of the drive motor can be lowered, and the situation that the drive motor is exploded or damaged due to too high temperature, and consequently the normal work of the water pump is influenced is avoided. By means of the detection contact and the buzzer, the detection contact can detect whether blockage happens in the water suction pump or not; and when blockage happens, the detection contact detects blockage, a signal is sent to the buzzer so that the buzzer can tweet, blockage is found conveniently in time, and the situation that a machine body runs in an idling manner, and consequently the service life of the water pump is shortened is avoided.

Description

technical field [0001] The invention relates to a water pump, in particular to a water pump with good cooling effect. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, a...

AI Technical Summary

Problems solved by technology

[0003] However, the existing water pumps generally have poor heat dissipation effects, and are prone to clogging, which cannot be found in time

Poor heat dissipation will cause the temperature of the motor in the water pump to continue to rise, and eventually it will be damaged or explode, resulting in the inability to work; if the blockage cannot be detected in time, it will cause the body to run idling and reduce the service life of the pump
