In figure: 1 is support, 2 is electronic for driving, and 3 is the pump housing, and 4 is impeller, and 5 is pump shaft, and 6 is impeller cover, and 7 is impeller blade, and 8 is fluid passage, and 9 is flowing hole, and 10 is shaft seal part.
Embodiment
As Fig. 1, shown in Fig. 2, one pole single suction double leaf road high-pressure service pump, comprise: support 1, drive electronic 2 and the pump housing 3, described drive motor 2 and the pump housing 3 are arranged on support 1, in the described pump housing 3, be provided with impeller 4, described impeller 4 is connected with drive motor 2 by pump shaft 5, between described pump shaft 5 and the pump housing 3, be provided with shaft seal part 10, described impeller 4 mainly consists of impeller cover 6 and impeller blade 7, the both sides of described impeller cover 6 are evenly provided with multiple impeller blades 7, formation fluid passage, space 8 between adjacent two impeller blades 7 of homonymy, the fluid passage 8 of described impeller cover 6 both sides is corresponding.
On described impeller cover 6, be also provided with the flowing hole 9 for being communicated with fluid passage, both sides 8.
The general employing of existing high-pressure service pump arranges impeller blade before impeller cover, wheel rotation, foreign material are entered in fluid passage, but because pressure is excessive, part foreign material enter in shaft seal cavity through the narrow and small gap between the impeller cover back side and the pump housing, shaft seal part is easily damaged, cause sealing difficulty.
The application adopts one pole single suction double leaf road impeller, in the both sides of impeller cover 6, impeller blade 7 is set, between adjacent two impeller blades 7 of homonymy, form fluid passage 8, and the fluid passage 8 of impeller cover 6 both sides is corresponding, has so formed one pole double leaf road impeller, again because drive motor 2 rotates by pump shaft 5 drives impeller 4, make the unique import a on the pump housing 3 produce negative pressure, formed one pole single suction double leaf road impeller, adopt this impeller, during work, foreign material enter from a in the fluid passage 8 in outside, by reason of heavy pressure simultaneously, also have part foreign material to enter in shaft seal cavity a2 through the narrow and small gap between impeller cover 6 back sides and the pump housing 3, again because the inner side of impeller cover 6 is provided with fluid passage 8 equally, impeller 4 rotates, make the same negative pressure that produces in shaft seal cavity a2, the foreign material that make to enter in shaft seal cavity a2 can flow out from the fluid passage 8 of impeller cover 6 inner sides in time, remain that the pressure at shaft seal cavity a2 place is in negative pressure state, prevent that foreign material from entering shaft seal cavity and damaging shaft seal part, prevent from causing pump to reveal and bearing damage, the effectively working life of extending shaft sealing while.
