Abstract
The utility model discloses a centrifugal water pump which comprises a pump casing, a pump base matched with the pump casing, an impeller arranged inside a cavity formed through assembling the pump casing and the pump base, and an impeller shaft connected with the pump shaft, wherein the impeller shaft is installed on the pump base, one end of the cavity located on one end of the pump casing is provided with a water inlet, the side of the cavity is provided with a water outlet, and the improvement of the water pump lies in that the side of the cavity is straight. The structure of the water pump can realize the processing and production of the compression casting process, and further realizes the purposes of improving the production efficiency and reducing the production cost of products.
Description
Technical field
The utility model relates to agricultural irrigation pump field, especially a kind of Centrifugal water pump.
Background technique
Existing a kind of agricultural irrigation formula water pump, its structure is: comprise pump case, with the pump seat of pump case coupling, be arranged at the impeller of the die cavity inside that pump case and pump seat assembling form, the impeller shaft that links to each other with impeller, wherein impeller shaft is loaded on the pump seat, be positioned on the described die cavity on the end of pump case and offer water intake, the side of described die cavity is provided with water outlet, wherein, the side of described die cavity is the camber setting of evagination.The water pump of this existing structure, its manufacture method is generally and adopts injection molding way to make, its material is made of plastics, has the advantage that the cost of material is low, but adopts the processing mode of injection moulding, its processing technology complexity, make that the product work efficiency is low, manufacture cost is too high, and because material is plastics, so quality of product is relatively poor, service life is short.For example a kind of overall plastic centrifugal pump announced of China ZL200720123343.2 just belongs to this situation.
Also have a kind of processing mode that adopts casting in addition in the prior art, but its preparation process is complicated more, and cost of material is not cheap yet, its comprehensive product cost is higher, so mode is eliminated substantially.
The water pump of this said structure of the prior art, because structure is limit, it can only take two kinds of above-mentioned processing modes to process, and can't realize advanced more processes such as die casting.So it has the product complex process all the time, the low excessively excessive defective of product overall cost that causes of manufacturing efficiency.
The model utility content
At the prior art above shortcomings, technical problem to be solved in the utility model is: design a kind of water pump of new structure, make it can realize the extrusion process processing, and then reach and enhance productivity, reduce the purpose of production cost.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
A kind of Centrifugal water pump, comprise pump case, with the pump seat of pump case coupling, be arranged at the impeller of the die cavity inside that pump case and pump seat assembling form, the impeller shaft that links to each other with impeller, wherein impeller shaft is loaded on the pump seat, be positioned on the described die cavity on the end of pump case and offer water intake, the side of described die cavity is provided with water outlet, and its improvements are: the side of described die cavity is a straight flange.
In the utility model, the side of described die cavity is a spiral type, helps water outlet like this, can improve the efficient of drawing water.
In sum, existing than in prior art, the technical program has following beneficial effect:
1, the utility model creatively changes the side of die cavity spirogyrate in original water pump into straight flange, makes this structure can adopt more advanced extrusion process manufacturing, can improve production efficient like this, thereby reduces the production overall cost.
2, the utility model adopts extrusion process, so its material is a metallic material, now than in injecting products, can make that quality of product is better, and service life is longer.
3, the utility model can adopt extrusion process, and preferably adopting metallic aluminium is raw material, so compare with the cast iron of prior art, its melting temperature metal is lower, and so energy saving more reduces greenhouse gas emission, and environment protection effect is good.
Description of drawings
Fig. 1 is the assembly structure schematic representation of the utility model pump case and pump cover; In the utility model, because of the place of its architecture advances only relates to pump case and pump cover, the structure that does not relate to impeller and impeller shaft, so the structure of pump case and pump cover only is provided in the accompanying drawing, to reach abundant disclosed purpose, during concrete enforcement, impeller and impeller shaft adopt and well known to a person skilled in the art that conventional structure gets final product.
Fig. 2 is the structural representation of facing of the utility model pump case.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the assembly structure schematic representation of the utility model pump case and pump cover; As shown in it, when this Centrifugal water pump is specifically implemented, comprise pump case 1, with the pump seat 2 of pump case 1 coupling, be arranged at the impeller of die cavity 3 inside that pump case 1 and pump seat 2 assemblings form, the impeller shaft that links to each other with impeller, wherein impeller shaft is loaded on the pump seat 2, be positioned on the described die cavity 3 on the end of pump case 1 and offer water intake 4, the side 6 of described die cavity 3 is provided with water outlet 5, and wherein: the side 6 of described die cavity 3 is a straight flange.During concrete enforcement, be preferably that side is vertical with both ends of the surface to be provided with.As shown in Figure 2, when specifically implementing, the side of described die cavity 3 integral body is spiral type, the overall radian of described vortex connects transition less than straight line between 360 ° and the two ends, water outlet promptly is arranged at the port of the outside end of vortex along swirl direction, help water outlet like this, can improve the efficient of drawing water.
Described extrusion process belongs to a kind of existing casting die forging processing molding method, is a kind of technology of finishing on the die casting die forging machine of special use.Its basic craft course is: molten metal elder generation low speed or high-speed casting fill in the die cavity of type progressive die tool, and mould has movable cavity surface, and it is along with the cooling procedure pressurization of molten metal is forged, and molten metal is solidified under pressure and form foundry goods.The method can be eliminated the shrinkage porosity defect of contraction cavity of blank, also can make the interior tissue of blank reach the broken crystal grain of forging attitude.Make that the product mechanical property process is better, and processing technology is simple, quick and processing modes such as injection moulding, casting now than, saved process time greatly.
The utility model protection domain is not restricted to this mode of execution; it can also make all equivalent variations known to a person of ordinary skill in the art in the protection domain of claim 1; preferably be set to be provided with vertical such as the die cavity side, if but others adopts oblique setting or stepped setting also should belong to protection domain of the present utility model with both ends of the surface.
