Description
Technical field
The present invention relates to a kind of single-pole single-suction double-blade high-pressure pump, belong to high-pressure pump technical field。
Background technology
High-pressure pump is to provide high voltage power for high-pressure delivery slime, sludge dewatering, cement mortar, for filter press, the aspects such as New Buildings, highway, subterranean railway, high-pressure pump also can be used in water under high pressure and take the photograph stream auxiliary rock coal breakage, the cleaning of underground piping, high-pressure water jet is bored a hole or other need with high pressure liquid fluid to be the field of power。
High-pressure pump common in the market is one pole single suction Dan Ye road high-pressure pump, it is operationally, often due to the work under bad environment of high-pressure pump, long-time use impurity easily enters shaft seal cavity along the small gaps between impeller and the pump housing, cause that axle leak sealing water foreign material seal in, damage bearing, bring a lot of inconvenience to daily productive life。
Summary of the invention
It is a kind of simple and reasonable for structure that the present invention overcomes the deficiency that prior art exists, technical problem to be solved there is provided, it is easy to seals, and alleviates axle envelope place pressure, the single-pole single-suction double-blade high-pressure pump in extending shaft sealing service life。
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: single-pole single-suction double-blade high-pressure pump, including: support, drive motor and the pump housing, described drive motor and the pump housing are arranged on support, it is provided with impeller in the described pump housing, described impeller is connected with drive motor by pump shaft, axle sealing it is provided with between described pump shaft and the pump housing, described impeller is mainly made up of impeller cover and impeller blade, the both sides of described impeller cover are evenly arranged with multiple impeller blade, composition fluid passage, space between adjacent two impeller blades of homonymy, the fluid passage of described impeller cover both sides is corresponding。
Described impeller cover is additionally provided with the flowing hole for connecting fluid passage, both sides。
The present invention compared with prior art had the beneficial effect that present configuration is simple, reasonable, by adopting bilobate road impeller, and on impeller cover, have flowing hole, for connecting the fluid passage of impeller cover both sides, make fluid inside passage and lateral fluid passage form balance in the high pressure interval of pump working, so that choma forms negative pressure between axle envelope, be prevented effectively from and cause that owing to pump working pressure is excessive foreign material enter shaft seal cavity, damage and seal, cause pump to reveal。Flowing hole acts primarily as the pressure of side liquid passage inside and outside balance impeller cover, reduces the vibration of water pump, extends water pump service life, makes water pump operation more steady。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described。
Fig. 1 is the structural representation of single-pole single-suction double-blade high-pressure pump of the present invention。
Fig. 2 is the partial enlarged drawing at A place in Fig. 1。
In figure: 1 is support, 2 is drive motor, 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 axle sealing。
Detailed description of the invention
Such as Fig. 1, shown in Fig. 2, single-pole single-suction double-blade high-pressure pump, including: support 1, drive motor 2 and the pump housing 3, described drive motor 2 and the pump housing 3 are arranged on support 1, it is provided with impeller 4 in the described pump housing 3, described impeller 4 is connected with drive motor 2 by pump shaft 5, it is provided with axle sealing 10 between described pump shaft 5 and the pump housing 3, described impeller 4 is mainly made up of impeller cover 6 and impeller blade 7, the both sides of described impeller cover 6 are evenly arranged with multiple impeller blade 7, composition 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。
Described impeller cover 6 is additionally provided with the flowing hole 9 for connecting fluid passage, both sides 8。
Existing high-pressure pump is generally adopted before impeller cover and arranges impeller blade, wheel rotation, foreign material are made to enter in fluid passage, but owing to pressure is excessive, part foreign material small gaps between the impeller cover back side and the pump housing enters in shaft seal cavity, make axle sealing be easily damaged, cause sealing difficulty。
The application adopts one pole single suction bilobate road impeller, namely arranges impeller blade 7 in the both sides of impeller cover 6, constitutes fluid passage 8, and the fluid passage 8 of impeller cover 6 both sides is corresponding, so namely defines one pole bilobate road impeller between adjacent two impeller blades 7 of homonymy；Again because drive motor 2 drives impeller 4 to rotate by pump shaft 5, the unique import a on the pump housing 3 is made to produce negative pressure, namely one pole single suction bilobate road impeller is defined, adopt this impeller, during work, foreign material enter in the fluid passage 8 in outside from a, simultaneously because pressure is big, part foreign material small gaps between impeller cover 6 back side and the pump housing 3 is also had to enter in shaft seal cavity a2, again because the inner side of impeller cover 6 is again provided with fluid passage 8, impeller 4 rotates, make to produce equally in shaft seal cavity a2 negative pressure, the foreign material in entrance shaft seal cavity a2 are enable to flow out from the fluid passage 8 inside impeller cover 6 in time, remain that the pressure at shaft seal cavity a2 place is in negative pressure state, prevent foreign material from entering shaft seal cavity and damage axle sealing, prevent from causing pump to reveal and bearing damage, simultaneously can service life of effective extending shaft sealing。
But owing to the gap between impeller cover 6 back side and the pump housing 3 is narrow and small, flow is just little, cause the water outlet requirement that cannot meet impeller cover 6 fluid inside passage 8, easily make to produce in impeller cover 6 fluid inside passage 8 vacuum, cause the vibrations of pump and the unstability of pump, unstability in order to avoid the vibrations of pump and pump, impeller cover 6 has multiple flowing hole 9, the fluid passage making impeller cover 6 both sides is connected, thus balancing the pressure of fluid passage inside and outside impeller cover 6, make pump overall operation steady, use more safe and reliable。
Above in conjunction with accompanying drawing, embodiments of the invention are explained in detail; but the present invention is not limited to above-described embodiment; in the ken that those of ordinary skill in the art possess; various changes can also be made obtaining under the premise without departing from present inventive concept, also should be regarded as protection scope of the present invention。
