Abstract

A water pump cooling structure comprises a motor, a pump body shell and an impeller; the cooling structure further comprises a cooling barrel and a connecting block; the cooling barrel is a hollow cylindrical body; the two ends of the cooling barrel are closed; one end of the cooling barrel is provided with a water inlet and a water outlet; the motor is arranged in the cooling barrel which is connected with a pump body in a sealed manner through the connecting block; a water inflow channel corresponding to the water inlet and a water outflow channel corresponding to the water outlet are formedin the connection block; the water inflow channel and the water outflow channel are communicated with the water inlet and the water outlet correspondingly; and a rear port ring is formed between theimpeller and the connection block, and is communicated with the water inflow channel and the water outflow channel. According to the water pump cooling structure, due to the fact that the outer surface of the motor is sleeved with the cooling barrel, media conveyed by a submersible electric pump cyclically flow in the cooling barrel to take away heat generated by the motor in the work process, sothat the motor is cooled, the motor can also be effectively cooled even though the motor is exposed in air, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a water pump cooling structure. Background technique [0002] Submersible electric pumps are mainly used in various municipal engineering, industrial buildings, pumping stations and other occasions for the drainage system of permanent ship locks. The drainage system of permanent ship locks includes water delivery corridor drainage and groove drainage systems. The pump is the most representative. In some occasions, very special requirements are put forward for the operating conditions of the submersible pump. For example, in a certain project, a total of 24 maintenance and drainage pump rooms are set up for the maintenance and drainage of water delivery valves. The maximum height difference of the collection wells 95.6m, the maximum head of the submersible electric pump is 100m, and the maximum diving depth is 95m. [0003] Such parameters are a new challenge for the design o...
