Description
Technical field
The present invention relates to water pump technologies, and in particular to water shutoff pumps.
Background technology
Dredged in China widely used in the industry of beach dredger carry out channel dredging, blow sea build up fields, the engineerings such as port construction, and
Water shutoff pump is the key equipment on dredger.Water shutoff pump is to carry out water shutoff for dredge pump axle envelope, prevents silt particle from entering dredge pump axle envelope, is protected
Protect the normal work of dredge pump.Can water shutoff pump safely and reliably run the service life for being directly related to construction speed and dredge pump.It is existing
Water shutoff pump be generally divided into high pressure water shutoff pump and low pressure water shutoff pump, for mesohigh water shutoff pump since flow velocity is high, impeller diameter is big, leads
Housing volume is caused to increase, under similary pressure, sectional area is big, therefore the pressure being subject to is big, this just requires higher to casing rigidity.Separately
Outside since water shutoff pump discharge is small, pressure is high, when the lift of pump is higher, single-stage pump can not be met the requirements, it is necessary to design multiple leaves
It takes turns to meet the requirements, impeller needs are installed in series, and the axial force of generation is big, and bearing is fragile, cause pump service life low.And
Containment member is equipped between dividing wall and main shaft sleeve in existing water shutoff pump configuration, containment member uses metal loop seals knot
Structure, during using metal loop seals structure, becket should leave certain gap between dividing wall inside, but due to chamber it
Between there are certain pressure difference, therefore the setting in the gap certainly will be there are leakage phenomenon, and it is at one to pump this gap value when just dispatching from the factory
In reasonable interval, with using, seawater especially is being conveyed when with corrosive liquids, gap width can be increasing, when
Gap width greatly to a certain extent after just affect the discharge capacity of pump.
Therefore, how existing high pressure water shutoff pump is improved makes it overcome the above problem, is those skilled in the art
A problem urgently to be resolved hurrily.
The content of the invention
It is an object of the present invention to provide one kind to have level Four impeller, and structure is reliable, good airproof performance, service life
Long novel high-pressure water shutoff pump.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of novel high-pressure water shutoff pump, is fixed including surrounding
The pump housing and pump cover of connection offer pump inlet and pump discharge on the pump housing, and the pump housing both ends each extend over out two axis
Body is held, being passed through on the bearing body has pump shaft, and bearing is provided between the pump shaft and the bearing body；It is characterized in that：Institute
It states and is fixed with one stage impeller, sencond stage impeller, three-level impeller and level Four impeller on pump shaft successively, inside the pump housing and the pump cover
Extend the first dividing wall, the second dividing wall and intermediate dividing wall, first dividing wall is located at the one stage impeller and described
Between sencond stage impeller, second dividing wall is between the three-level impeller and the level Four impeller, the intermediate dividing wall
Between the sencond stage impeller and the three-level impeller, and middle standing pillar bolt is provided at the intermediate dividing wall, it is described
Middle standing pillar bolt passes through the pump housing and the pump cover, and is fixedly connected with the pump housing and the pump cover.
As an improvement, being provided with bearing holder (housing, cover) between the bearing body and the bearing, it is provided on the bearing body removable
The bearing cap unloaded.
Preferably, offering tapped blind hole on the pump housing, smooth bore is offered on the pump cover, the centre is stood
Column bolt is through the smooth bore and is threadedly connected in the tapped blind hole.The setting of above-mentioned pore structure, facilitates in installation
Between upstanding studs, and directly tighten fixed, other parts be not required.
Further preferably, the middle standing pillar bolt is two, and is symmetrically disposed on the pump shaft both sides.Bonding strength is more
Height, stress are also more uniform.
As an improvement, it is close to be both provided with axis at first dividing wall, second dividing wall and the intermediate dividing wall
Component is sealed, anti-wearing liner is provided between the sealing component and the pump shaft.The setting of anti-wearing liner can reduce the pump housing, pump
The abrasion of lid and pump shaft improves the service life of water shutoff pump.
It being further improved, also extends impeller wall inside the pump housing and the pump cover, the impeller wall is four, and point
Not Wei Yu the one stage impeller, the sencond stage impeller, the three-level impeller and the level Four impeller end face outside at, the leaf
Wheel containment member, the wheel containment member and the one stage impeller, the sencond stage impeller, the three-level leaf are both provided at wheel wall
Wear-resisting choma is provided between wheel and the level Four impeller.The setting of wear-resisting retaining ring can reduce the abrasion of the pump housing, pump cover and impeller.
Improve the service life of water shutoff pump.
Compared with prior art, the advantage of the invention is that：The lift that the impeller setting of level Four can pump water shutoff in total carries
Height meets use demand；And the additional of intermediate dividing wall sets the intensity that can increase water shutoff pump, reduces the radial direction suffered by pump shaft
Power improves the service life of pump shaft；The setting of middle standing pillar bolt can improve the coupling mechanism force of the pump housing and pump cover, increase water shutoff pump
Intensity can also strengthen the connection sealing between the pump housing and pump cover；The setting of bearing holder (housing, cover) can reduce the abrasion of bearing, and improving it makes
With the service life, while the detachable setting of bearing cap, bearing holder (housing, cover) is convenient for changing, reduces the maintenance cost of water shutoff pump.
