Description
Technical field
The utility model relates to a kind of centrifugal self-priming pump.
Background technique
Though existing centrifugal self-priming pump also has certain self-priming height and can reach the effect of carrying liquid, but because the difference of structural type, itself have some intrinsic defectives: axial dimension is bigger, and the mounting point is limited, is difficult to be applied on boats and ships naval vessels and vehicle; The speed that sucts is slow, influences the utilization efficiency of self-priming pump, causes certain wasting of resources; Suction head is low, in use field and region certain restriction is arranged all.
Summary of the invention
The utility model purpose is to propose a kind of high rotating speed centrifugal self-priming pump, and it has solved technical problems such as existing centrifugal self-priming pump volume is big, the speed that sucts is slow, suction head is low.
Technical solution of the present utility model is:
A kind of high rotating speed centrifugal self-priming pump comprises pump case, impeller, and its special way is, the water intake front end of described impeller is provided with an inducer with the pump shaft coaxial rotation.
Above-mentioned high rotating speed centrifugal self-priming pump also comprises gearbox, and described gearbox is arranged on the pump shaft input end.
Above-mentioned gearbox comprises casing, case lid, transmission device, it is characterized in that: upper half part of the right flank of described casing is provided with the casing opening end, and described case lid can fasten sealing with the casing opening end; Described transmission device comprises input shaft, output shaft and the driving gear that is arranged between casing front-end face and ear end face.
Be provided with seal arrangement between the impeller of above-mentioned high rotating speed centrifugal self-priming pump and the pump case, described seal arrangement comprises seal ring, retainingf key, the back-up ring, the circlip groove that is arranged on the pump case inner side surface that are arranged between pump case and the impeller, be arranged on the axial outer groove of pump case inner side surface and be arranged on the axial inner groovy of seal ring outer side surface, it is interior in order to prevent the seal ring axial play that described back-up ring is arranged on circlip groove, and described retainingf key is arranged between outer groove and the inner groovy in order to limit the rotation of seal ring circumferencial direction.
The utility model has the advantages that:
1, volume is little.The utility model self-priming pump adopts optimizes the waterpower design, after the gearbox speedup, and the rotational parts high speed rotating, impeller, inducer and pump case size reduce, and inducer is arranged in the pump case, thus the overall volume of entire pump group is little, and in light weight.Gearbox adopts and divides half semi-open type structure, and volume obviously reduces.
2, suction head is big.The utility model oil pump has increased inducer in pump inlet, adopts the inducer and the impeller optimum organization of the design of optimal design method, has strengthened the anti-cavitation ability of pump group greatly, and suction capacity also just is better than common centrifugal self-priming pump greatly.
3, it is fast to suct speed.The utility model self-priming pump has been owing to increased inducer, so can adopt the gearbox speedup, makes pump rotatable parts rotating speed height, and the speed that sucts is fast, and the speed that sucts is better than NBS greatly.
4, be easy for installation and maintenance.Because basic structure is similar to the ordinary construction self-priming pump with profile, have simple in structure and maintaining such as makes things convenient at advantage.
5, sealing is reliable, efficient is high.The utility model adopts unique seal arrangement, can guarantee that sealing is reliable, the efficient height.
