The pump comprises a pump body, a liquid inlet, a liquid outlet, a pump tire, a shaft and an impeller, the impeller is an integrated body composed of an impeller body connected with the shaft and 5-10 uniformly-distributed flexible blades arranged in a radial manner, the root of each of the flexible blades is connected with the impeller body, the top of each of the flexible blades has a spherical end, the pump tire is positioned in the pump body, the material of the pump tire is stainless steel, the impeller is positioned in the cavity of the pump tire, the liquid inlet and the liquid outlet are positioned over the pump body, the pump tire has an annular structure, through holes respectively communicated with the liquid inlet and the liquid outlet are positioned over the pump tire, and the pump tire is positioned between the liquid inlet and the liquid outlet and has a thickened segment for realizing the compressive deformation of the heads of the flexible blades of the impeller. The above structure can be adopted by the liquid feeding pump used for seawater desalination, so the liquid feeding pump used for seawater desalination has the advantages of reduced making cost, improved production efficiency and convenient maintenance and assembling.
Description
Technical field
The present invention relates to displacement pump, relate in particular to the fluid filling pump that can be used for desalination of sea water.
Background technique
For adapting to the user demand of different condition, pump of a great variety.Use extensive displacement pump class to have: gear pump, plunger pump, vane pump etc.; Non-displacement pump class has: centrifugal pump, axial-flow pump etc.Heavy engineering machinery comprises the pump housing, pump cover, external gear, internal gear and backbone sealing ring with fluid filling pump at present, internal gear and external gear engagement, such structure, the required precision of the pump housing, external gear, internal gear is high, side direction, tip circle and external tooth precision are quite high, roughness is little, easily occurs that the pump self-absorption function of assembling after part processing error declines to a great extent even to inhale not feed liquor, can not arrange air and cannot work.Another kind easily occurs that situation is stuck after assembling, and inside and outside gear turns motionless.Product rejection rate is higher, and manufacture cost is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fluid filling pump that can be used for desalination of sea water, and the fluid filling pump that this kind can be used for desalination of sea water can reduce fabricating cost, enhances productivity.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of fluid filling pump that can be used for desalination of sea water, it comprises pump housing body, liquid entering hole, liquid outlet, pump tire, axle and impeller, described impeller forms one by the impeller body being connected with axle and radial 5-10 uniform flexible blade and forms, the root of each described flexible blade is connected with impeller body, the top of each flexible blade has spherical termination, described pump tire is positioned in pump housing body, the material of described pump tire is stainless steel, described impeller is positioned at the cavity of pump tire, described liquid entering hole and liquid outlet are positioned at pump housing body top, described pump tire is loop configuration, the top of pump tire has the through hole communicating with liquid entering hole and liquid outlet respectively, the described pump position of foetus has the circle thickening that can make the flexible blade termination extrusion-deformation of impeller be able to discharge opeing and lacks between two liquid mouths.
The both sides of described pump housing body are respectively arranged with protecgulum and middle cover.
Between described protecgulum and pump housing body, be furnished with respectively the wear plate vertical with shaft centre line between middle cover and pump housing body.
The quantity of the flexible blade of described impeller is six.
The fluid filling pump that the present invention can be used for desalination of sea water adopts such structure, and processing cost reduces, and reduces product rejection rate, can reduce fabricating cost, enhance productivity, suitable production in enormous quantities, keep in repair easy to assemblyly, there is common mechanical general knowledge and can operate under the guidance of operating instruction.
Accompanying drawing explanation
The fluid filling pump that the present invention be can be used for to desalination of sea water below in conjunction with accompanying drawing is described in more detail;
Fig. 1 is the structural representation that the present invention can be used for the fluid filling pump of desalination of sea water;
Fig. 2 is the A-A sectional structure schematic diagram shown in Fig. 1;
In Fig. 1, Fig. 2,1, pump tire; 2, pump housing body; 3, impeller; 4, axle; 5, protecgulum; 6, middle cover; 7, bearing; 8, wear plate; 9, seal ring; 10, liquid outlet; 11, flexible blade; 12, liquid entering hole; 13, impeller body.
Embodiment
As shown in Figure 1 and Figure 2, the fluid filling pump that can be used for desalination of sea water comprises pump housing body 2, pump tire 1, impeller 3, axle 4, protecgulum 5, middle cover 6, liquid entering hole 12, liquid outlet 10, wear plate 8 and seal ring 9, impeller 3 forms one by impeller body 13 and radial six uniform flexible blades 11 and forms, impeller 3 connects by pin or flat key with axle 4, the root of each flexible blade 11 is connected with impeller body 13, and the top of each flexible blade 11 has spherical termination; Pump tire 1 cylindrical matches with pump housing body 2 endoporus, pump tire 1 is positioned in pump housing body 2, liquid entering hole 12 and liquid outlet 10 are positioned at pump housing body 2 tops, pump tire 1 is loop configuration, the material of pump tire is stainless steel, the top of pump tire 1 has the through hole communicating with liquid entering hole 12 and liquid outlet 10 respectively, and the pump position of foetus has lacking with pump tire ring all-in-one-piece circle of thickening between two through hole, can make the flexible blade termination extrusion-deformation of impeller.The both sides of pump housing body 2 have respectively protecgulum 5 and middle cover 6, and axle 4 two ends are supported by the bearing 7 of protecgulum 5 and middle cover 6 interior selflubricatings.Between protecgulum 5 and pump housing body 2, there is respectively the wear plate vertical with shaft centre line 8 between middle cover 6 and pump housing body 2, can significantly reduce resistance to motion.
Motor arrives impeller by coupling by transmission of power.When impeller operation, flexible blade is squeezed termination during to the top of pump tire, and the circle that pump tire thickens lacks helix and basic circle smooth transition, utilizes plastic deformation volume-variation, flexiblely contacts good airproof performance with rigidity, and head pressure liquid is pushed in realization.When flexible blade leaves, thicken when place, it is large that flexible blade elasticity diastole volume becomes, and realizes the process from imbibition, and continuous operation realizes the liquid process of omitting in printing of taking out normally.
The fluid filling pump that the present invention can be used for desalination of sea water adopts such structure, processing cost reduces, reduce product rejection rate, reduce fabricating cost, enhance productivity, suitable production in enormous quantities, keeps in repair easy to assembly, without professional workforce, there is common mechanical general knowledge and can operate under the guidance of operating instruction.
