Description

Pump with self-cooling system

Technical Field

The utility model relates to a pumping technical field specifically is a take pumping of self-cooling system.

Background

The pumping structure in the prior art does not have a self-cooling system, and in the use, when the impeller runs, the shaft core and the shaft sleeve can rub to generate high temperature, liquid around the shaft core does not flow, heat is slowly dissipated, the inner magnetic coating position is easily melted and deformed, and pumping accessories are damaged to cause the pump to normally run, so that the problem can be effectively solved after the self-cooling system is added in the pump.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a take pumping of self-cooling system to axle core and axle sleeve can rub when solving the current pumping impeller operation that proposes in the above-mentioned background art and produce high temperature, and liquid does not flow on every side, and the heat gives off slowly, easily leads to interior magnetism to glue the position and melt the deformation, causes the problem that the pumping accessory damaged.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a take pumping of self-cooling system includes the pumping body, the protecgulum, the quiet ring of protecgulum, impeller rotating ring, the impeller, interior magnetic unit, the axle sleeve, the thrust ring, the back lid, the connecting seat, the footing, the axle core, water conservancy diversion ring and auxiliary impeller, the inside of pumping body is provided with the axle core, the axle sleeve is installed in the outside of axle core, the outside of axle sleeve is provided with interior magnetic unit, the front end of axle core is provided with the impeller, auxiliary impeller is installed to the impeller rear end, auxiliary impeller's rear end is provided with the water conservancy diversion ring, the impeller rotating ring is installed to the front end of impeller, the front end of impeller rotating ring is provided with the protecgulum, the quiet ring of protecgulum internally mounted, the thrust ring cup joints on the axle core, and install the rear side at the axle sleeve, the rear end of axle core is.

Compared with the prior art, the beneficial effects of the utility model are that: the self-cooling pump is simple in structure, low in cost and reasonable in structural design, the auxiliary impeller and the flow guide ring are additionally arranged behind the impeller, when the impeller rotates, liquid can be thrown away by the auxiliary impeller through the flow guide ring to form flowing liquid, so that high temperature generated by friction of the shaft core and the shaft sleeve is taken away, a self-cooling effect is achieved, and the service life of the pump is prolonged.
