Embodiment
The invention provides a kind of self prime pump bottom, realized self prime pump bottom and power engine case lid are united two into one, made the two become an one-piece parts, reduced the volume of self prime pump and power engine integral body, save material, and then reduced the manufacture cost of self prime pump.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who is obtained under the creative work prerequisite.
Please refer to accompanying drawing 1-2, the structural representation of the self prime pump that Fig. 1 provides for the embodiment of the invention; The structural representation of the self prime pump bottom that Fig. 2 provides for the embodiment of the invention.
The self prime pump bottom that the embodiment of the invention provides, its both sides link to each other with power engine with the pump housing 1 of self prime pump respectively; This self prime pump bottom 4 is provided with the line shaft mounting hole, and this line shaft mounting hole is divided into Bearing Installation section 41, oil sealing construction section 42 and water seal construction section 43 successively from a side of the impeller 3 of the extremely close described pump housing 1 of a side of close described power engine.
The self prime pump bottom that the embodiment of the invention provides is provided with the line shaft mounting hole, and this line shaft mounting hole is divided into Bearing Installation section, oil sealing construction section and water seal construction section successively from a side of the impeller of the extremely close pump housing of a side of close power engine.This self prime pump bottom makes that the line shaft of power engine is directly coupled, and promptly the self prime pump bottom also becomes the case lid of power engine, has realized self prime pump bottom and power engine case lid are united two into one, and makes the two become an one-piece parts; This self prime pump bottom is provided with water seal construction section and the oil sealing construction section that water seal and oil sealing are installed simultaneously, but has guaranteed the line shaft proper functioning.Therefore, this self prime pump bottom has reduced the volume of self prime pump and power engine integral body, has saved material, and then has reduced the manufacture cost of self prime pump.
