The utility model relates to a light, the easy installation of centrifugal pump, low, corrosion -resistant, the long service life of cost of maintenance.
Description
Technical field
The utility model belongs to industrial pump technical field, more particularly to a kind of centrifugal pump.
Background technology
Centrifugal pump can be widely used for the industries such as electric power, metallurgy, coal, building materials slurry of the conveying containing solid particle, farmland
Irrigation and drainage, petrochemical industry, power water feeding, mining and shipbuilding industry conveying liquid etc..As thermal power plant's hydraulic(-ash) sluicing, technics of metallurgy mineral dressing factories and miness are starched
Conveying, coal washery coal slurry and dense medium conveying etc..
Centrifugal pump is to be rotated using impeller and make water that centrifugal motion occur come work.Water pump is before activation, it is necessary to make pump
Water is full of in shell and suction hose, then starts motor, make pump shaft impeller and water do high speed rotary motion, water occurs centrifugation fortune
It is dynamic, impeller outer edge is thrown toward, the runner of Jing volute pump cases flows into the pressure pipe road of water pump.During work, pump needs to be placed on land,
Suction hose is placed in water, in addition it is also necessary to fill pump startup.In addition slush pump and submerged centrifugal pump be by structure due to being limited, during work
Motor needs to be placed on the water surface, and pump is put in water, it is therefore necessary to fixed, and otherwise, motor drops to and can cause in water motor and scrap.
And because main axis length is typically fixed, so pump is installed and used cumbersome, the occasion of application is limited by a lot.It is existing from
The electric machine main shaft of heart pump directly and impeller connection, once main shaft is damaged and may be accomplished by keeping in repair whole motor or more
Change, high cost, and electric machine main shaft is made of metal, and wears no resistance, and easily corrodes, service life is shorter.
Utility model content
The purpose of this utility model there are provided it is a kind of it is light, be easily installed, maintenance cost is low, it is corrosion-resistant, use the longevity
The long centrifugal pump of life, to overcome the deficiencies in the prior art.
For achieving the above object, the utility model provides a kind of centrifugal pump, including the pump housing, and in the pump housing leaf is provided with
Wheel, the impeller is provided with impeller nut, and the impeller nut is connected with power transmission shaft and fixes；The side of the pump housing is by more
Individual screw is connected with pump cover, and the opposite side of the pump cover is by multiple screw connection suspension bodies；The lower end of the suspension body is provided with
Suspension strut；The power transmission shaft is through pump cover and suspension body, and power transmission shaft is provided with seal member, power transmission shaft with the junction of pump cover
Bearing is provided with the junction of suspension body；The both sides of the bearing are provided with fluid-tight set；The main shaft and countershaft of the power transmission shaft is
Hollow-core construction, and connected by flat key；
The power transmission shaft includes main shaft and countershaft, and the main shaft and countershaft length ratio are 3:2.
Preferably, the main shaft and countershaft outer surface are coated with antirust coat.
Preferably, the thickness of the antirust coat is 1mm-2mm.
The beneficial effects of the utility model are：
1st, the machine envelope parts such as axle sleeve and machine sealed cover, weight saving are reduced, and pump is in hgher efficiency, is easy to use, easily
In installation.
2nd, main shaft, countershaft hollow design, reduce material, have saved cost, when main shaft or countershaft need repairing replacing
Main shaft can be disconnected individually to be changed.
3rd, impeller is detachable, when impeller is keeped in repair, it is only necessary to change the part for damaging, and saves the maintenance cost of centrifugal pump.
4th, power transmission shaft outer surface coating antirust coat, strengthens the wear-corrosion resistance of power transmission shaft, extends centrifugal pump
Service life.
