Problems solved by technology

[0002] Usually, the dust suppression vehicle is equipped with a single multi-stage centrifugal pump for the sprayer. Before working in winter, due to the low outside temperature, the remaining water in the pump after working the previous day has not been completely drained, which will cause the impeller in the pump to be damaged. The gap between the impeller and the stirring plate is filled with thin ice, so that the impeller and the stirring plate are frozen together, and the impeller will be damaged when the water pump starts
[0003] In the past, when starting the dust suppression vehicle in winter, the problem of water pump freezing can only be solved by pouring hot water.

Abstract

The invention discloses a water pump heating system, and relates to the field of water pumps for dust suppression vehicles. The water pump heating system comprises an automobile chassis, a valve device, a heat conduction system and a water pump system. The automobile chassis comprises an automobile silencer, an automobile exhaust pipe and an automobile girder, and the outer surface of the automobile silencer is connected with the lower surface of the automobile girder. An electric control system comprises an electric control switch and a control line. According to the water pump heating system, a three-way air valve is additionally arranged at the tail gas exhaust end of the whole vehicle, during work in spring, summer and autumn, vehicle tail gas is directly exhausted through the air valve, before preparation work and during vehicle heating in winter, the three-way air valve is switched through a switch in a cab, and the vehicle tail gas is transferred to a heat collection cover through the heat conduction pipe. And then the collected heat is dissipated to a pump body shell by the heat collection cover, so that the pump body with frozen residual water is heated, ice blocks between an impeller and a stirring disc in the pump body are quickly melted, and the impeller in the pump body is prevented from being frozen by the ice blocks and the water pump is prevented from being damaged when the water pump is started.
