Abstract

The invention discloses a motor protection type fire pump. The pump comprises a base, a pump body and a motor, wherein a heat dissipation box is fixed to the end of the motor, a water inlet pipe and awater outlet pipe are fixed to the two ends of the pump body respectively, the water outlet pipe is wound around the side wall of the motor, and a spacer bush is fixed to the inner wall of the heat dissipation box; a ventilation groove communicating with the interior of the motor is formed in the side wall of the heat dissipation box, an air inlet hole is formed in the side wall of the spacer bush in a penetrating mode, an exhaust hole is formed in the side wall of the heat dissipation box in a penetrating mode, and a contraction sheet is fixed to the inner wall of the spacer bush. The waterpump is advantaged in that the drainage pipe is wound on the surface of the motor, so that heat emitted by the motor can be absorbed when the pump body pumps water flow, the heat of the motor is effectively dissipated through a small amount of continuous absorption for many times, meanwhile, the temperature of output water flow is not affected, and the service life of the motor is effectively prolonged; and the motor can work for a long time under high power.

Description

technical field [0001] The invention relates to the technical field of fire pumps, in particular to a motor protection type fire pump. Background technique [0002] The fire pump is installed on the fire truck and fixed fire extinguishing system, and is used as a special pump for transporting liquid fire extinguishing agents such as water or foam solution. [0003] At present, most fire pumps use the motor to drive the impeller to pump water, and the motor is used as the driving force. However, when the motor is actually working, it will heat itself, or it will be overloaded and broken, which will cause the motor to fail to work normally. Existing fire pumps do not provide sufficient protection for the motor, so that the internal heat accumulation of the motor affects the service life when the motor is in use, and the protection measures cannot be provided in time when the motor line fails, causing serious damage to the motor and even causing more serious safety accidents. ...
