Abstract
The utility model discloses a fully plastic centrifugal water pump, which comprises a pump, an impeller in the pump and a pump flange. Wherein, the pump, the impeller and the pump flange. The pump is divided into two halves, of which one half is a pump shell and the other half is a pump cap. The pump shell is connected with the pump cap through a bolt. A central part on an external surface of the pump shell and the pump cap is provided with a close nipple. The close nipple on the pump shell is connected with the pump flange. The close nipple on the pump cap is connected with a water pipe. The impeller is centrally arranged on the pump. In addition, the impeller is composed of an impeller blade body provided with an impeller blade and an impeller cap. Compared with cast iron centrifugal pump compared, the novel fully plastic centrifugal pump has the advantages of light weigh, beautiful appearance, excellent consistency of product size and production precision, high sealing performance, water leakage resistance and long service life. The full plastic centrifugal pump better facilitates detachment, installation, carriage and utilization and is suitable for motors and gasoline and diesel oil generators.
Description
Technical field the utility model relates to a kind of pump, the overall plastic centrifugal pump that particularly a kind of field irrigation is used.
Background technique is commercially available centrifugal pump at present, and each single-piece pump case, pump cover, pump flange and the impeller etc. that constitute centrifugal pump unit all are by the iron casting moulding, and pump flange and pump case are cast as one, and the impeller raw material of pump also is mainly cast iron and aluminum alloy material, thereby causing existing cast iron centrifugal pump manufacturing efficiency low, dimensional uniformity and poor accuracy are produced seriously polluted, the energy consumption height, the user uses inconvenience, product cost height, appearance poor, also owing to not resistance to chemical attack, working life is not long yet.
The summary of the invention the purpose of this utility model is to provide a kind of overall plastic centrifugal pump at the above-mentioned defective that exists in the prior art.
For realizing described purpose, overall plastic centrifugal pump of the present utility model, comprise impeller and pump flange in the pump housing, the pump housing, the described pump housing, impeller and pump flange are working of plastics, therefrom form by the pump case and the pump cover of dimidiation by the pump housing for the described pump housing, be connected by bolton between pump case and the pump cover, described pump case and pump cover outer surface center portion are equipped with threaded coupling, and the threaded coupling on the pump case is connected with the pump flange; Threaded coupling on the pump cover is connected with water pipe, and described impeller is located at the centre of the pump housing; Described impeller is made of the impeller lamellar body and the bucket cover that have impeller blade, is provided with attachment post on impeller blade, is provided with through hole on bucket cover and the corresponding position of attachment post, and impeller lamellar body and bucket cover are fastenedly connected by attachment post and through hole.Centrifugal pump body by 2 original parts, is decomposed into 3 parts, i.e. pump case, pump cover and pump flange, thus can adopt the injection moulding method for processing to be processed into overall plastic materials and parts; Impeller is decomposed into impeller lamellar body and bucket cover 2 parts, equally also is to be convenient to adopt the injection moulding method for processing to be processed into overall plastic materials and parts, will promptly form overall plastic centrifugal pump after all parts combinations.And prior art constructions can't realize molding and forming.
Described pump cover inward flange is provided with a circle groove, built-in Stamping Steel Ribbon.To guarantee the sealing of the pump housing.
Overall plastic centrifugal pump of the present utility model than the advantage of cast iron centrifugal pump is: in light weight, outward appearance is beautiful; Product size and accuracy of manufacturing high conformity; Sealability is strong, antileaking.Because product has adopted wear-resisting, high strength, cold-resistant, heatproof, the plastic material of corrosion never, makes the long service life of its working life than the cast iron centrifugal pump.Overall plastic centrifugal pump of the present utility model has fully been avoided the weak link of cast iron centrifugal pump structure design, overall plastic centrifugal pump disassemble or assemble, carries, uses more convenient, and it not only can cooperate generator to use, and also can cooperate gasoline, diesel generator to use.
Description of drawings is further described the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a schematic side view of the present utility model
Embodiment
As shown in Figure 1, 2, overall plastic centrifugal pump of the present utility model, comprise impeller 2 and pump flange 3 in the pump housing 1, the pump housing 1, the described pump housing 1, impeller 2 and pump flange 3 are working of plastics, therefrom form by the pump case 11 and the pump cover 12 of dimidiation by the pump housing 1 for the described pump housing 1, be connected by bolton between pump case 11 and the pump cover 12, described pump case 11 is equipped with threaded coupling 4 and 5 with pump cover 12 outer surface center portions, and the threaded coupling 4 on the pump case 11 is connected with pump flange 3; Threaded coupling 5 on the pump cover 12 is connected with water pipe, and described impeller 2 is located at the centre of the pump housing 1; Described impeller 2 is made of impeller lamellar body 21 that has impeller blade 23 and bucket cover 22, on impeller blade 23, be provided with attachment post 24, be provided with through hole 25 on bucket cover 22 and attachment post 24 corresponding positions, impeller lamellar body 21 and bucket cover 22 are fastenedly connected by attachment post 24 and through hole 25.
Described pump cover 12 inward flanges are provided with a circle groove 6, built-in Stamping Steel Ribbon 7.
Overall plastic centrifugal pump of the present utility model has all carried out significant improvement on product material and project organization, thereby solved the defective of cast iron centrifugal pump, but using effect is identical.
Overall plastic centrifugal pump newly developed, main body partly is that pump case 11 is injection molded respectively with pump cover 12 and pump flange 3 by three, change injection moulding production into by casting, former cast iron centrifugal pump is that pump case 11 and pump cover 12 2 are partly formed, former cast iron centrifugal pump flange 3 and pump case 11 are one, and overall plastic centrifugal pump flange 3 newly developed and pump case 11 respectively are one with pump cover 12 on producing, wherein pump flange 3 and pump case 11 be for being threaded, and the pump case 11 of cast iron and overall plastic centrifugal pump be bolt being connected of pump cover 12 and connect.
The annex impeller 2 that uses in the overall plastic centrifugal pump newly developed has in addition also adopted the plastic material molding and forming, the impeller raw material material of former various pumps is mainly cast iron and aluminum alloy, the mode of production is casting, compare with the injection moulding mode of production of plastic material impeller 2, it is low that the impeller 2 of Foundry Production mode exists manufacturing efficiency, need machinery reprocessing, shortcomings such as dimensional uniformity and poor accuracy, production is seriously polluted, energy consumption is high, product cost is high, appearance poor.
