Abstract
A heat insulating structure of a hot water circulating pump consists of a pump body, an impeller, a pump cover and a pump shaft. The pump cover is arranged on the pump body; the pump shaft is arranged in the pump body; the impeller is arranged on the pump shaft and located between the pump body and the pump cover; a thermal baffle is arranged inside the pump body and between the impeller and the pump cover; the thermal baffle is fixedly connected with the pump cover; a heat insulating chamber is arranged between the thermal baffle and the pump cover; a rib plate is arranged in the heat insulating chamber; a hollow cavity is arranged inside the thermal baffle; a rib plate is arranged inside the hollow cavity; the hollow cavity is fully sealed and filled with gas or liquid, or vacuumed; the thermal baffle prevents thermal medium from transmitting the heat to the direction of pump cover through the impeller; and the rib plates can prevent the heat convection. The heat energy used for pumping liquid and directly transmitted to a cooling system of the pump cover, a sealing system, and a suspension frame component is reduced, thus ensuring that the cooling system can fully cool the sealing system, the suspension frame component, etc. The sealing system can operate reliably for a long time, and the waste of the heat energy used for pumping the medium is reduced, thus saving energy resource.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pump, particularly hot water circulating pump, a kind of specifically heat-insulating structure that is used for hot water circulating pump.
Background technique:
Hot water circulating pump adopts the mode of water flowing to come the member of coolant pump.But, high-temperature water that pump is pumped or heat transfer medium with heat still can be transmitted among pump cover or the sealing system, cause a sealing difficult problem, bearing is fragile, cooling system can be taken away again and pump the contained heat energy of liquid simultaneously.
Summary of the invention:
The purpose of this utility model provides a kind of heat-insulating structure that is used for hot water circulating pump, and the described this heat-insulating structure that is used for hot water circulating pump will solve the unfavorable technical problem of linkage structure of prior art chemical pump pump shaft and motor.
This heat-insulating structure that is used for hot water circulating pump of the present utility model is made of the pump housing, impeller, pump cover and pump shaft, described pump cover is arranged on the pump housing, described pump shaft is arranged in the pump housing, described impeller is arranged on the pump shaft and between the pump housing and pump cover, wherein, be provided with thermal baffle in the described pump housing, between impeller and the pump cover, described thermal baffle is fixedlyed connected with pump cover, is provided with heat-insulation chamber between thermal baffle and the pump cover.
Further, be provided with gusset in the described heat-insulation chamber.
Further, be provided with cavity in the described thermal baffle.
Further again, be provided with gusset in the described cavity, cavity is hermetically sealed, is filled with gas or liquid or vacuum in the cavity.
Working principle of the present utility model is: thermal baffle prevents that thermal medium from transmitting heat by impeller to the pump cover direction.Thermal baffle can adopt metalwork or high temperature resistant heat insulation material, and thermal baffle can constitute by welding or casting, and thermal baffle can be connected with pump cover by the form that bolt or interference fit or welding or pump housing pump cover fold.The gusset that is provided with in the heat-insulation chamber between pump cover and the thermal baffle can prevent thermoconvection.The gusset that is provided with in the cavity in the thermal baffle also can prevent thermoconvection.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is provided with thermal baffle between impeller and pump cover, having reduced pump greatly pumps liquid and is directly transferred to heat energy among pump cover cooling system, sealing system, the sprung parts, thereby guarantee the abundant coolant seal of cooling system system, sprung parts etc., sealing system can reliably and for a long time be moved.Simultaneously, reduce the meaningless dissipation that pump is pumped the heat energy of medium, saved the energy.
