The utility model relates to a kind of pump, particularly a kind of hot water circulating pump.
[background technique]
Need to use hot water circulating pump in the pipeline in metallurgy, power station, light textile, chemical industry, heating and bootstrap system or the transporting system of the hot water circuit in the loop or organic heat exchange medium, because the medium and the pump that are recycled are to be under the high temperature, common recycle pump can not use owing to there is following defective: when carrying high temperature media, the ordinary cycle pump does not have cooling unit, and mechanical seal and bearing all can be unable to born high temperature and be damaged.
Therefore, be necessary to design a kind of novel hot water circulating pump, to overcome above-mentioned defective.
[model utility content]
The purpose of this utility model provides a kind of hot water circulating pump that can overcome above-mentioned defective.
The utility model hot water circulating pump comprises the pump housing with entery and delivery port, also comprise impeller, rotatingshaft, pump cover, carriage, between described carriage and the rotatingshaft bearing is set, described bearing is fixed by bearing cap, the intermediate support that between carriage and pump cover, connects hollow, described carriage is connected with described center bearing bracket, and the inner chamber of wherein said intermediate support is the first circulation cooling chamber, and described carriage inner chamber is provided with second cooling chamber.
Wherein said hot water circulating pump is the one step single sucking volute centrifugal pump of horizontal radial subdivision rear opening structure.
Wherein between described pump cover and rotatingshaft Sealing is set, described Sealing is connected a side of pump cover by gland, and above-mentioned wherein a bearing cap, Sealing, gland are arranged in the first circulation cooling chamber of described intermediate support.
Wherein said rotatingshaft is provided with axle sleeve, and described Sealing is the filler that is arranged between described axle sleeve and pump cover.
Because adopt said structure, the hot water circulating pump of the utility model has following beneficial effect:
Described carriage is connected with described center bearing bracket, make the even unlikely distortion of temperature expansion, the inner chamber of intermediate support is provided with the first circulation cooling chamber, the bearing, pump cover and the Sealing that can be rotatingshaft carry out external refrigeration, described carriage inner chamber is provided with second cooling chamber and can be rotatingshaft and bearing cooling, guarantees the hot water circulating pump proper functioning.
