Manufacturing method for centrifugal pump with motor automatic cooling function

Abstract

The invention provides a manufacturing method for a centrifugal pump with a motor automatic cooling function. The centrifugal pump comprises a pump body and a motor which is fixedly connected with thepump body through a transmission rod, wherein the pump body comprises a water inlet tube and a water outlet tube; each of the tail end of the water inlet tube and the tail end of the water outlet tube is equipped with a flange; the bottom of the pump body is fixedly connected with a mounting base; the lower end of the motor is fixedly equipped with a motor base; an air bellow is mounted on the upper end surface of the motor base; a plurality of ventilating holes are formed in the side surface of the air bellow; the motor is positioned on the inner part of the air bellow; a fan is mounted at the upper end of the air bellow; and a mobile power supply used for providing working power is mounted inside the fan. The manufacturing method has the beneficial effects that the temperature of the motor is kept within a normal working temperature range through an air-cooling mode, and therefore, harmful gas is not generated during operation of the motor; moreover, other chemical refrigerants arenot needed, and natural air flow is utilized to achieve the purpose of cooling the fan, so that the manufacturing method is energy-saving and environmentally friendly; and the service life of the motor can be further prolonged.

Description

technical field [0001] The invention relates to the technical field of liquid conveying pumps, in particular to a preparation method of a centrifugal pump with a motor automatic cooling function. Background technique [0002] The normal operation of the centrifugal pump requires the motor to provide power guarantee. However, the motor will generate a lot of heat during the working process. If the excess heat cannot be quickly transferred to the outside world, the internal parts of the motor will be aggravated due to excessive temperature. This will significantly shorten the service life of the motor. It can be seen that how to develop a preparation method of a centrifugal pump with the automatic cooling function of the motor, by arranging a cooling device at the motor position, and then keeping the temperature of the motor within a suitable working temperature range, is an urgent need for those skilled in the art at present. solved problem.
