Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of Domestic blower pump of band housing 2, including pump case, pump case upper end is provided with motor casing, impeller it is provided with in pump case, stator 1 and rotor 4 it is provided with in motor casing, being provided with rotating shaft in the middle part of rotor 4, rotating shaft one end is connected with impeller, it is characterized in that: be provided with housing 2 between stator 1 and rotor 4, housing 2 one end is provided with shielding end cap 5, end cap is provided with pre-ceramic ring 7, and housing 2 other end end is provided with rear ceramic ring 9, and described rotating shaft is ceramic shaft 3, pre-ceramic ring 7 and rear ceramic ring 9 are set in rotating shaft two ends, and shielding end cap 5 is additionally provided with priming hole 6.Between rotor 4 and stator 1, arrange housing 2 to be effectively prevented stator 1 and intake, cause motor damage, original ball bearing is replaced with ceramic shaft 3 and holds, reduce noise, decrease friction, improve the efficiency of motor, ceramic shaft 3 is contracted and is included pre-ceramic ring 7, rear ceramic ring 9 and ceramic shaft 3, and plain cloth end cap is provided with priming hole 6, the water of impeller cavity can be guided to housing 2 internal, in order to lubricate ceramic shaft 3 and pre-ceramic ring 7, rear ceramic ring 9, reduce ceramic shaft 3 and hold abrasion, improve the life-span.
As in figure 2 it is shown, one end that described ceramic shaft 3 is connected with impeller is provided with conduction hole 12, ceramic shaft 3 other end side is provided with outlet 8, and outlet 8 is just to rear ceramic ring 9 inwall.When working due to booster pump, water in pump case has higher pressure, water in pump case can be guided between rear ceramic jacket and the competing surface of ceramic shaft 3 by offering of conduction hole 12, ceramic jacket and ceramic shaft 3 after lubrication, it is to avoid rear ceramic ring 9 can not get lubrication and causes serious wear.
As in figure 2 it is shown, described housing 2 and shielding end cap 5 are tightly connected.Housing 2 and shielding end cap 5 are tightly connected, and can effectively prevent the water in housing 2 from flowing out between housing 2 and shielding end cap 5, produce drainage, cause motor stator 1 to be intake.Interference fit can be used between housing 2 and shielding end cap 5, housing 2 end face is provided with protuberance, shielding end cap 5 is provided with the depressed part matched with protuberance, depressed part is round table-like, the diameter of depressed part opening part is less than the diameter bottom depressed part, and shielding end cap 5 is by being stamped to form, and depressed part opening part is provided with fin 14, protuberance surface and fin 14 interference fit seal, protuberance root is provided with the groove 13 that the flange with depressed part opening part cooperates.Fin 14 card is embedded in groove 13, can effectively prevent housing 2 and the disengaging of shielding end cap 5.The competing surface of shielding end cap 5 of this external housing 2 can also arrange sealant layer, to increase sealing effectiveness.
As in figure 2 it is shown, described rear ceramic ring 9 end face is communicated with hole 10.Intercommunicating pore 10 arrange can by rear ceramic ring 9 lower end water guide to rear ceramic ring 9 upper end, enable water to after upper and lower two end faces of ceramic ring enter together between ceramic ring 9 and the gap of ceramic shaft 3, it is lubricated between rear ceramic ring 9 and rotating shaft, it is ensured that rear ceramic ring 9 and the lubricant effect of pottery rotating shaft.The quantity of intercommunicating pore 10 is preferably two, on the one hand improves through-current capability, prevents one of them blocking from causing water can not enter into rear bearing set upper side, also avoids offering the intensity of ceramic ring 9 after intercommunicating pore 10 quantity too much affects simultaneously.
The above is only exemplary embodiment of the present utility model, and not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
