Description
Technical field
The present invention relates to a kind of assembly of pump, and relate more specifically to a kind of special ceramic double-lining pipe and production method thereof.
Background technique
Under a lot of working staties, requirement equipment must possess high temperature resistant, corrosion-resistant and anti abrasive performance, pumping unit as oil field oil recovery usefulness, it is installed in underground hundreds of rice, it is even the local work of going up km, from starting working until damage is to work without cessation, and underground itself have very high ground temperature, adds that equipment itself is ceaselessly twitched also can produce high temperature; Oil or other sub-terrain mines materials itself have very severe corrosive again, even even so strong corrosion can't be resisted in the stainless steel capital; Simultaneously, oil is by from underground releasing the time, must there be silt to be carried secretly together, the existence of silt, well-known special cermacis has characteristics such as high temperature resistant, corrosion-resistant and wear-resistant, its performance is far superior to metallic material, but because it fails to change the relatively poor critical defect of ceramic existing toughness, so still be difficult under the industrial and mineral condition, directly use independently.
As desire under the industrial and mineral condition, to make full use of and bring into play the performance advantage that special cermacis has, method commonly used is to allow itself and other materials, realizes the purpose of being scheduled to as being combined into compound material with traditional metallic material.But because of not finding at present a kind of effective ways or binding material that combines between special cermacis and the other materials that be suitable for solving as yet, used binding material is again formulated by the number of chemical material mostly, as long as a certain chemical material during it is formed can not adapt to the abominable operating conditions of high temperature, corrosion or wearing and tearing, this binding material will go wrong; Equally, the method for selecting for use is inappropriate or structure is inappropriate, equally can go wrong.In the prior art:
For example, the Chinese patent " 90216983.1 abrasion-proof corrosion-proof ceramic chamber lining oil well pump " that on January 30th, 1991 was announced, it is to adopt the more piece ceramic cylinder jacket, inner room has adhesive layer, forms pump line by gasket structure between collet threaded joint and cylinder sleeve up and down.The described ceramic cylinder jacket two end brush coating sticks of this patent, but this adhesive is not shock-resistant and corrosion, can not address the leakage concern.
And for example, the Chinese patent of announcing on February 19th, 1992 " 91219434.0 long-lived renewable potteries lining oil well pump ", its pump line is made up of outer tube, more piece cylinder sleeve, two external pipe thread joints, and described cylinder sleeve is made up of steel circumferential band and ceramic chamber lining.The hot interference of the hoop of cylinder sleeve is loaded on outside the ceramic jacket, binds round an end and is longer than the cover of making pottery, and the other end is shorter than the cover of making pottery, and ceramic jacket exposes and easily bumps and damage; The hoop hot jacket then can't hi-Fix outside ceramic jacket, is not to overlap pine, and internal diameter can't be concentric, and clear-cut exactly cover does not advance.
For another example, June in 1997 notice of authorization on the 11st Chinese patent " the durable oil well pump of 95228715.3 ceramic inlaid cylinder bodies ", pump line is by metal outer pipe, the more piece ceramic cylinder jacket, more piece ceramic cylinder jacket two end metal guide sleeves, outer tube two end inipples are formed; Plunger is by metal inner pipe overcoat band skirt tetrafluoro overcoat, and two end moving valves are formed.This pump injects viscose glue between the outer tube of pump line and cylinder sleeve, mobile poor because of viscose glue, can't thoroughly solve the vacancy pore so far, can not annotate reality, can not hug pithos, misplaces, falls cover, leakage; Pump rod overcoat tetrafluoro cover, owing to various heavy corrosions, sand abrasion, wear resistant corrosion resistant is also poorer than original steel.
For another the Chinese patent " 97242707.4 special cermacis tubing pump " of notice of authorization on the 2nd June in 1999, dress more piece special cermacis lining in metal outer pipe, metal outer pipe and special cermacis inner room inject the expansion Bond and constitute the oil well pump pump housing; The oil well pump piston is by core barrel, the special ceramic jacket of overcoat, and piston rod two ends are respectively adorned a moving valve, and core barrel and special cermacis inner room be with the adhesive cementation, the formation piston rod.The pump line of this pump exists outer tube and special cermacis inner room equally, and the property problem produces injecting glue because adhesive flows the space pore, and pottery overlaps dislocation, falls insurmountable defectives such as cover, leakage; The space pore also takes place and misplaces, falls cover in piston rod core barrel and special cermacis inner room adhesive cementation.
