Abstract
The utility model provides a kind of plunger pump bushing type plunger, comprise the plunger be placed in plunger cylinder, it is characterized in that the plug that plunger at one end is provided with its diameter and plunger cylinder and adapts, the other end is set to the plunger rod that diameter is less than plug, and sleeve pipe and locking nut is arranged with on this plunger rod, the external diameter of this sleeve pipe is identical with plug external diameter, can conveniently by the setting of sleeve pipe on plunger, rubbing surface is made to change sleeve outer wall face into by original plunger face, after casing wear is serious, the sleeve pipe that only need more renew just can continue to use, whole the scrapping of plunger is avoided to abandon, not only avoid the excess waste of material and cost, and bring facility to maintenance.
Description
Technical field
The utility model relates to a kind of plunger, particularly a kind of bushing type plunger of plunger pump, belongs to Machine Design manufacturing technology field.
Background technique
Plunger pump is a kind of reciprocating in plunger cylinder by plunger, causes sealed volume change in plunger cylinder and produces pressure difference, and then completing the device of Liquid transfer.Due to plunger pump work time, plunger is frequently movement in cylinder body, and therefore plunger belongs to vulnerable part.At present, most enterprises is all the selection carrying out plunger material according to the characteristic of conveying liquid, and overall processing forms.In use once wearing and tearing exceed requirement, be difficult to repair, its whole scrapping can only be abandoned, so just cause the excess waste of material.Not only increase the cost of production of enterprise, and a large amount of discarded plunger is also unfavorable for environmental protection.Therefore be necessary to be improved prior art.
Summary of the invention
The plunger used for solving existing plunger pump is difficult to repair after excessive wear, can only whole scrap, cause the serious problem of waste, the utility model provides a kind of bushing type plunger pump.
The utility model is completed by following technical proposal: a kind of plunger pump bushing type plunger, comprise the plunger be placed in plunger cylinder, it is characterized in that the plug that plunger at one end is provided with its diameter and plunger cylinder and adapts, the other end is set to the plunger rod that diameter is less than plug, and sleeve pipe and locking nut is arranged with on this plunger rod, the external diameter of this sleeve pipe is identical with plug external diameter, by the setting of sleeve pipe, rubbing surface is made to change sleeve outer wall face into by original plunger face, the sleeve pipe that only need more renew after casing wear is serious just can continue to use, whole the scrapping of plunger is avoided to abandon.
Described plunger rod is provided with annular groove, is provided with seal ring in annular groove, makes to form effective sealing between sleeve pipe and plunger rod by seal ring.
Be provided with annular groove inside described plug, in annular groove, be provided with seal ring, make to form effective sealing between plug and sleeve pipe and plunger rod by seal ring.
Thread section bolt on described locking nut and plunger rod, to complete the installation of sleeve pipe and fixing by locking nut.
The utility model has following advantages and effect: adopt such scheme, can conveniently by the setting of sleeve pipe on plunger, rubbing surface is made to change sleeve outer wall face into by original plunger face, after casing wear is serious, the sleeve pipe that only need more renew just can continue to use, avoid whole the scrapping of plunger to abandon, not only avoid the excess waste of material and cost, and bring facility to maintenance.Be a desirable plunger pump in fact.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The plunger pump bushing type plunger that the utility model provides, comprise the plunger be placed in plunger cylinder, wherein, plunger at one end is provided with the plug 1 that its diameter and plunger cylinder adapt, the other end is set to the plunger rod 2 that diameter is less than plug 1, and sleeve pipe 3 and locking nut 6 is arranged with on this plunger rod 2, the external diameter of this sleeve pipe 3 is identical with plug 1 external diameter, by the setting of sleeve pipe 3, rubbing surface is made to change sleeve pipe 3 outer wall into by original plunger face, when the sleeve pipe 3 that only need more renew after sleeve pipe 3 serious wear just can continue to use, whole the scrapping of plunger is avoided to abandon; Described plunger rod 2 right-hand member is provided with annular groove 4, is provided with seal ring 5 in annular groove 4, makes to form effective sealing between sleeve pipe 3 and plunger rod 2 by seal ring 5; Described plug 1 inner side surface is provided with annular groove, is provided with seal ring 8 in annular groove, makes to form effective sealing between plug 1 and sleeve pipe 3 and plunger rod 2 by seal ring 8; Thread section 7 bolt of described locking nut 6 and plunger rod 2 left end, to complete the installation of sleeve pipe 3 by locking nut 6 and to fix.
