Problems solved by technology
During operation, due to the influence of the temperature of the conveyed medium on the center height of the pump, the coaxiality deviation of the pump is relatively large, resulting in vibration and noise in the pump
Not only affects the use environment, but also greatly shortens the service life of bearings and couplings

The invention relates to a pump center supporting structure for eliminating the function of heat expansion. The pump center supporting structure comprises a pump body of horizontal structure, wherein, the center of the pump body is provided with a pump shaft, and supporting legs are respectively connected to the outer walls of both sides of the pump body and are positioned in a horizontal plane passing through the shaft axis of the pump shaft. The lower side of each supporting foot is provided with an upright post. Any upright post is provided with a water cooling cavity on the end on which the upright post is connected with the supporting foot,. The supporting feet of the pump are supported on the central axis plane of the pump body, the temperature of media causes the pump body to expand along the central axis plane towards the periphery, and the center height of the pump can be kept basically unchanged. When the temperature of the media is higher, by arranging the water cooling cavity on the supporting end of the upright post, the temperature difference of the supporting face can be lower, thereby keeping the center height of the pump basically unchanged and meeting the requirement of the pump on coaxiality. The structure solves the technical problem that the pump of horizontal structure is affected by the heat expansion.
Description
Technical field: [0001] The invention relates to the mechanical field, in particular to a pump, in particular to a central support structure of the pump for eliminating thermal expansion. Background technique: [0002] For pump products with horizontal structure, the pumps are not coaxial. During operation, due to the influence of the temperature of the conveyed medium on the center height of the pump, the coaxiality deviation of the pump is relatively large, resulting in vibration and noise in the pump. It not only affects the use environment, but also greatly shortens the service life of bearings and couplings. Invention content: [0003] The object of the present invention is to provide a pump center support structure for eliminating the effect of thermal expansion, the pump center support structure for eliminating the effect of thermal expansion should solve the high thermal expansion of the pump center of the horizontal structure pump in the prior art Affected by te...
