Embodiment
Below in conjunction with accompanying drawing, the 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 the amendment not having creative contribution as required by those skilled in the art after reading this specification sheets, but as long as being all subject to the protection of patent law in right of the present utility model.
Such as Fig. 1, shown in Fig. 2 and Fig. 3, the Domestic blower pump of a kind of band centrifugal impeller, comprise pump case 1, pump case 1 is provided with water-in 3 and water outlet 4, pump case 1 side is provided with annular runner 5, runner is provided with opening and is connected with water outlet 4, motor 2 it is provided with above pump case 1, the motor shaft 6 of motor 2 extend in pump case 1 and is connected with impeller 7, described impeller 7 is centrifugal impeller 7, impeller 7 comprises top board 15 and base plate 16, blade 10 it is fixed with between top board 15 and base plate 16, base plate 16 center is provided with water sucking mouth 17, water-in 3 on pump case 1 extends to bottom pump case 1 and is formed for the mouth of a river 9, for the mouth of a river 9 just to water sucking mouth 17. arrange like this for the mouth of a river 9 and water sucking mouth 17, when topping-up pump works, water flows into pump case 1 from water-in 3, and flow out from for the mouth of a river 9, from the water flowed out for the mouth of a river 9 by, in water sucking mouth 17 intake impeller 7 impeller 7 base plate 16, the water in intake impeller 7 is thrown away by the blade 10 on impeller 7, increase the flow velocity of current, and produce pressure, make water flow in annular runner 5 simultaneously and finally flow out from water outlet 4. it is between top board 15 and base plate 16 due to blade 10 and it is fixedly connected with base plate 16 with top board 15, during work, the rigidity of blade 10 is better, shake less, be conducive to reducing noise, simultaneously for the mouth of a river 9 just to water sucking mouth 17, the water that water-in 3 is come in directly is thrown away by impeller 7 after entering impeller 7, decrease the disturbance of pump case 1 water flow inside, it is to increase the working efficiency of topping-up pump, add lift. base plate 16 arrange can by water slower for the flow velocity come for the mouth of a river 9 and after impeller 7 accelerates flow velocity faster water separate, avoid producing turbulent flow for the mouth of a river 9 place, produce bigger liquid and hinder.
As shown in Figure 2, being provided with ring groove 8 for side, the mouth of a river 9, water sucking mouth 17 is in ring groove 8, is in water sucking mouth 17 for the mouth of a river 9, and the internal diameter of water outlet reduces bottom pump case 1 gradually from impeller 7 base plate 16. The internal diameter of water sucking mouth 17 increases from top to bottom gradually, water sucking mouth 17 and the internal diameter for the mouth of a river 9 place are less, stronger suction can be produced, can be inner by quick intake impeller 7 under the suction of impeller the last 7 when water flows out from the confession mouth of a river 9, simultaneously the internal diameter of water sucking mouth 17 near base plate 16 place is bigger, the impeller 7 can be made, it is to increase the efficiency of topping-up pump water-dispersion to be accelerated between blade 10 fast.
As shown in Figure 4, blade 10 comprises long blade 101 and short blade 102, and long blade 101 and short blade 102 are arc, and rotation direction when arc opening works with impeller 7 is contrary, and short blade 102 is between adjacent two long blade 101 and close top board 15 excircle. blade 10 is arranged like this, the working efficiency of the entirety of pump can be improved, when the water of water sucking mouth 17 enters between top board 15 and base plate 16, water moves to impeller 7 edge along the surface of arc shaped blade, the water sucked can be accelerated rapidly by arc shaped blade 10, impeller 7 water sucking mouth 17 place is made to produce bigger vacuum tightness, increase suction when impeller 7 absorbs water, arc shaped blade 10 bends against impeller 7 sense of rotation near impeller 7 excircle section simultaneously, the time that water accelerates in impeller 7 can be increased, improve speed when water throws away from impeller 7 further, improve supercharging pump lift. the area due to water sucking mouth 17 place when arranging of short blade 102 is less, if blade 10 all extend into this place, water sucking mouth 17 place can be caused to be blocked by blade 10, produces bigger liquid resistance, is unfavorable for improving the working efficiency of topping-up pump. being arranged on of short blade ensures while not reducing blade quantity that water sucking mouth water suction is smooth and easy, ensures supercharging pump lift and efficiency.
As shown in Figure 3, top board 15 is provided with mount pad 13, and mount pad 13 is embedded with copper cover 11. The toughness having had due to copper and distortion ability, by technique scheme, can adopt shrink-fit with motor shaft 6 when impeller 7 is connected, directly inserted by motor shaft 6 in copper cover 11, be convenient to installation and have and connect effect preferably.
As depicted in figs. 1 and 2, motor shaft 6 is ceramic shaft, and ceramic shaft is also combined with the ceramic ring 12 for supporting ceramic shaft, and ceramic shaft center is provided with priming hole 14. Use ceramic shaft and ceramic ring 12 to replace spot contact bearing, decrease the vibrations of topping-up pump, reduce further noise when topping-up pump works, reduce friction, it is to increase the working efficiency of topping-up pump simultaneously. Can being introduced by the high pressure water at impeller 7 place between ceramic ring 12 and ceramic shaft by arranging priming hole 14 at ceramic shaft center, lubrication ceramic ring 12 and ceramic shaft, reduce friction, prevents ceramic ring 12 and ceramic shaft abrasion simultaneously.
The above is only exemplary embodiment of the present utility model, but not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
