Abstract
The utility model discloses a pump ceramic plunger. The pump ceramic plunger comprises a plunger shell, a plunger core body, a plunger connecting rod and a gland, wherein the plunger core body is arranged in the plunger shell and does stretchy movement, the gland is pressed at one end of the plunger core body, the plunger connecting rod is arranged on the plunger core body in a sleeved mode, and the plunger core body and the plunger connecting rod are matched through a ratchet and are fixed and limited through the gland at the end of the plunger core body. By means of the mode, the high pressure resistance, corrosion resistance and abrasion performance of the plunger can be improved, the service life of the plunger is prolonged, production efficiency is improved, connection is firm, and the pump ceramic plunger is easy to maintain and replace.
Description
Technical field
The utility model relates to plunger pump field, particularly relates to a kind of pump ceramic plunger.
Background technique
In oil extraction in oil field system, high-pressure plunger pump is one of capital equipment.And in high-pressure service pump, plunger is critical component, it is also main easily damaged parts.Therefore, the performance quality of plunger is often directly connected to high pressure pump performance and working efficiency.
At present, the on-the-spot plunger using is all to make of alloyed steel conventionally, main have chrome-faced plunger and a carburizing and quenching plunger, these plungers wear no resistance, and in the working environment of high temperature, high pressure, are easily corroded, and not only itself shorter in life-span, and in use also to adjust continually compression and change sealed packing, have a strong impact on working efficiency, increase workman's labor intensity and the time, bring a lot of hidden danger to safety in production simultaneously.And because the life-span of plunger is shorter; often needing to change, is a very thing for trouble but change plunger, after needing to shut down, the oil pump of depths one, two kms and plunger are hung on to ground after cleaning change; expend a large amount of manpowers, oil recovery efficiency reduces greatly simultaneously.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of pump ceramic plunger, has improved high pressure resistant, corrosion protection and the wear-resisting property of plunger, has extended the working life of plunger, has improved manufacturing efficiency, connect simultaneously firm, for ease of maintenaince change.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of pump ceramic plunger is provided, comprise: plunger housing, be arranged on described plunger enclosure interior and do plunger core body, plunger connecting rod and the gland of fore and aft motion, described gland is pressed together on one end of described plunger core body, described plunger connecting rod is set in described plunger core body, between described plunger core body and described plunger connecting rod, match by ratchet, and fixing and spacing by the described gland of described plunger core body end.
In preferred embodiment of the utility model, described plunger housing is metal material.
In preferred embodiment of the utility model, described plunger housing external surface is coated with ceramic membrane, increases wear-resisting property.
In preferred embodiment of the utility model, described plunger core body is ceramic material, improves decay resistance, increases the service life.
In preferred embodiment of the utility model, described ceramic material is aluminium sesquioxide, and hardness is high, is insoluble to soda acid, corrosion-resistant, good insulating.
In preferred embodiment of the utility model, described gland is metal material.
The beneficial effects of the utility model are: the utility model is by adopting the metal shell of ceramic core body and plating ceramic membrane, its wear resistance is improved greatly, solve the Anticorrosion of plunger, greatly extend the working life of plunger, ensure that plunger pump can normally move in any severe working environment, enhances productivity; In addition, sheathed plunger connecting rod in plunger core body adopts ratchet to coordinate simultaneously, has both increased the intensity of plunger, makes again the combination between the two more tight, connects firm, for ease of maintenaince replacing.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of pump of the utility model ceramic plunger one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, plunger housing, 2, plunger core body, 3, plunger connecting rod, 4, gland, 5, ratchet.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of pump ceramic plunger, comprise: plunger housing 1, be arranged on described plunger housing 1 inside and do plunger core body 2, plunger connecting rod 3 and the gland 4 of fore and aft motion, described gland 4 is pressed together on one end of described plunger core body 2, described plunger connecting rod 3 is set in described plunger core body 2, between described plunger core body 2 and described plunger connecting rod 3, match by ratchet 5, and fixing and spacing by the described gland 4 of described plunger core body 2 ends, it is tightr, firm to connect, and has increased the intensity of plunger.
Wherein, described plunger housing 1 is metal material, and is coated with ceramic membrane at the outer surface of described plunger housing 1, increases its wear-resisting property.
Described plunger core body 2 is ceramic material, and described ceramic material is aluminium sesquioxide, and hardness is high, is insoluble to soda acid, and corrosion-resistant, good insulating, has improved decay resistance, has extended working life.
Described gland 4 is metal material, can, at the outer surface coated ceramic film of described gland 4, increase its wear-resisting property.
When making, need at high temperature sintering, conventionally adopt 1550-1650 DEG C of high temperature, ensure that the outer surface roughness Ra of plunger core body 2 is less than or equal to 0.2 μ m simultaneously, end face squareness is less than or equal to 0.03 μ m, and its wear resistance can exceed the more than 6-8 times of common metal plunger.
The utility model has disclosed a kind of pump ceramic plunger, by adopting the metal shell of ceramic core body and plating ceramic membrane, its wear resistance is improved greatly, solve the Anticorrosion of plunger, greatly extend the working life of plunger, ensure that plunger pump can normally move in any severe working environment, enhances productivity; In addition, sheathed plunger connecting rod in plunger core body adopts ratchet to coordinate simultaneously, has both increased the intensity of plunger, makes again the combination between the two more tight, connects firm, for ease of maintenaince replacing.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
