Abstract
The utility model provides a wear -resisting plunger, be in including plunger casing, setting inside plunger body and the plunger connecting rod who is concertina movement of plunger casing, the plunger is deepened to plunger connecting rod one end, and this internal and coordinated through ratchet and plunger body and is connected the plunger body is close to plunger connecting rod's one end and passes through gland nut and plunger connecting rod fixed connection to it is fixed through locking nut locking. The beneficial effects of the utility model are that improved the plunger high pressure resistant, anticorrosive and wear resistance, prolonged the life of plunger, improved production efficiency, connect firm, easy maintenance simultaneously and change.
Description
Technical field
This utility model belongs to plunger pump technique field, especially relates to a kind of Wear-resisting plunger.
Background technology
In oil extraction in oil field system, high-pressure plunger pump is one of capital equipment.And in high-pressure pump, plunger is critical component, it also it is main consumable accessory.Therefore, the performance quality of plunger is often directly connected to high pressure pump performance and work efficiency.
At present, the plunger of onsite application is the most all to make of steel alloy, main has chrome-faced plunger and carburizing and quenching plunger, these plungers wear no resistance, high temperature, high pressure working environment in be easily corroded, not only life-span itself is shorter, and to adjust compression the most continually and change sealed packing, have a strong impact on work efficiency, increase labor intensity and the time of workman, bring a lot of hidden danger to safety in production simultaneously.And owing to the life-span of plunger is shorter; often needing to change, but changing a plunger is a thing the most troublesome, after the oil pump of depths one, two km and plunger being hung on ground after needing to shut down, cleaning is changed; expending substantial amounts of manpower, oil recovery efficiency is substantially reduced simultaneously.
Utility model content
This utility model, mainly solving the technical problems that provide a kind of Wear-resisting plunger, improves high pressure resistant, anticorrosion and the anti-wear performance of plunger, extends the service life of plunger, improve production efficiency, be simultaneously connected with firm, for ease of maintenaince change.
The technical solution of the utility model is: a kind of Wear-resisting plunger, including plunger housing, it is arranged on and inside described plunger housing, does plunger body and the plunger connecting rod of stretching motion, in plunger body is goed deep in described plunger connecting rod one end and it is connected with plunger body by ratchet, it is connected by clamp nut and plunger connecting rod are fixing near one end of plunger connecting rod in described plunger body, and is locked by inverse-locking nut screw.
Further, it is filled with adhesive between described plunger connecting rod and inverse-locking nut screw.
Further, described plunger connecting rod includes that connecting rod stem, described connecting rod stem are sleeved in plunger body, and the rear end of described connecting rod stem is extended with in the middle part of connecting rod, in the middle part of described connecting rod, rear end is provided with connecting rod afterbody, is provided with escape in the middle part of connecting rod and between connecting rod afterbody.
Further, described plunger body is ceramic material.
Further, described plunger body top being provided with fillet R, fillet R is 0.3mm.
This utility model has the advantage that with good effect: owing to using technique scheme, owing to using technique scheme, plunger body uses ceramic material, its wearability is made to be greatly improved, solve the Anticorrosion of plunger, substantially prolongs the service life of plunger, it is ensured that plunger displacement pump can be properly functioning in any severe working environment, improve production efficiency；It addition, plunger body is set in plunger connecting rod, carries out front-end and back-end by gland and clamp nut respectively and fix, both added the intensity of plunger, make again combination therebetween the tightst, connect firm, for ease of maintenaince change.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
Shown in structural representation as of the present utility model in Fig. 1, this utility model provides a kind of Wear-resisting plunger, including plunger housing 1, it is arranged on internal plunger body 2 and the plunger connecting rod 3 doing stretching motion of described plunger housing 1, it is connected with plunger body 2 in plunger body 2 is goed deep in described plunger connecting rod 3 one end and by ratchet 4, it is connected by clamp nut 5 is fixing with plunger connecting rod 3 near one end of plunger connecting rod 3 in described plunger body 2, and is locked by inverse-locking nut screw 6.
It is filled with adhesive between described plunger connecting rod 3 and inverse-locking nut screw 6.Described plunger connecting rod 3 includes connecting rod stem 31, described connecting rod stem 31 is sleeved in plunger body 2, the rear end of described connecting rod stem 31 is extended with in the middle part of connecting rod 32, and in the middle part of described connecting rod, 32 rear ends are provided with connecting rod afterbody 34, are provided with escape 33 in the middle part of connecting rod between 32 and connecting rod afterbody 34.
Described plunger body 2 is ceramic material.It is 0.3mm that described plunger body 2 top is provided with fillet R, fillet R.
The work process of this example: the Wear-resisting plunger that this utility model provides, described plunger housing 1 is metal material, and has ceramic membrane at the outer surface of described plunger housing 1, increases its anti-wear performance.Described plunger body 2 is ceramic material, and described ceramic material is aluminium sesquioxide, and hardness is high, insoluble in soda acid, and corrosion-resistant, good insulating, improve decay resistance, extend service life.
Ensureing that outer surface roughness Ra of plunger body 2 is less than or equal to 0.03 μm less than or equal to 0.2 μm, end face squareness, its wearability can be beyond more than 6-8 times of common metal plunger simultaneously.
This utility model discloses a kind of Wear-resisting plunger, by using plunger body 2 and the plunger housing 1 of plated ceramics thin film of ceramic material making, its wearability is made to be greatly improved, solve the Anticorrosion of plunger, substantially prolongs the service life of plunger, ensure that plunger displacement pump can be properly functioning in any severe working environment, improve production efficiency；It addition, plunger body 2 is set in plunger connecting rod 3, carries out front-end and back-end fix by gland 4 and clamp nut 5 respectively, both added the intensity of plunger, made again combination therebetween the tightst, connect firm, for ease of maintenaince change.
Above an embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All impartial changes made according to this utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
