Abstract
The invention discloses a ceramic plunger for a pump. The ceramic plunger comprises a plunger shell, a plunger core arranged inside the plunger shell to be in extensible motion, a plunger connecting rod and a gland, the gland presses at one end of the plunger core, the plunger connecting rod sleeves on the plunger core, and the plunger core and the plunger connecting rod are matched with each other through ratchets and fixed and limited through the gland on the end portion of the plunger core. By the above mode, resistance to high pressure, corrosion resistance and wear resistance of the plunger can be improved, service life of the plunger can be prolonged, production efficiency can be improved, and the ceramic plunger is firm in connection and easy to maintain and replace.
Description
Technical field
The present invention relates to plunger pump field, particularly relate 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.
Summary of the invention
The technical problem that the present invention 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 present invention 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 a preferred embodiment of the present invention, described plunger housing is metal material.
In a preferred embodiment of the present invention, described plunger housing external surface is coated with ceramic membrane, increases wear-resisting property.
In a preferred embodiment of the present invention, described plunger core body is ceramic material, improves decay resistance, increases the service life.
In a preferred embodiment of the present invention, described ceramic material is aluminium sesquioxide, and hardness is high, is insoluble to soda acid, corrosion-resistant, good insulating.
In a preferred embodiment of the present invention, described gland is metal material.
The invention has the beneficial effects as follows: the present invention 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, guarantee 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pump of the present invention 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 invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
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 ℃ of high temperature, guarantee 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 present invention 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, guarantee 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 embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention 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 invention.
