Abstract
Disclosed are a well-drilling PEEK wear resistant cylinder bushing and a hot inlaying and loading method thereof. The hot inlaying and loading method includes: subjecting an outer surface of an outer bushing of metal to rough machining and an inner surface to finish machining; fixing a shell bushing of the metal on a designated position of a die; after the die and the outer cylinder bushing are mounted in place, injecting PEEK powder into a forming cavity, wherein the PEEK powder is formed by die pressing at the temperature ranging from 380DEG C to 390DEG C and die pressing time of 4-5 hours; removing the die and subjecting a workpiece to machining after the workpiece is back to normal temperature; subjecting the inner surface to finish machining to required size, wherein cylindricity and glossiness of the surface are needed to meet the requirements. The metal is carbon steel in material. The average service life of the PEEK wear resistant cylinder bushing exceeds 750hours, and what is worthy of specially mentioning is that the service life index exceeds foreign advanced level; production cost of the entire cylinder bushing is well optimized, cost of a single piece is decreased by 20% as compared with that of a conventional bi-metal cylinder bushing, and cost is greatly saved.
Description
Technical field
The invention belongs to the manufacture method of the main easily damaged parts of drilling pump, PEEK wear resisting cylinder jacket and hot inserting method thereof for especially a kind of drilling well.
Background technique
At present, the cylinder sleeve of each oil field drilling pump used majority is bi-metal liner, and neck bush employing centrifugal pressure casting, the rich chromium cast iron that wear resistance is very high are made.What adopt due to inside and outside cover is interference fit, at cylinder sleeve, uses after wear out failure, if want, neck bush is extruded, and more renews comparatively difficulty of neck bush, therefore, after neck bush lost efficacy and scraps, must change in the lump by inside and outside lining.So,, in the situation that external bushing does not have damage just not scrap, to complete equipment, increased suitable expense.According to investigation, learn, every average life of such cylinder sleeve is in 500h left and right.Annual national oil field need to consume several ten thousand, has caused great waste.
Summary of the invention
The object of the invention is for domestic existing cylinder sleeve of drilling pump cost is high at present, the not easily changeable problem of neck bush, provides PEEK wear resisting cylinder jacket and hot inserting method thereof for a kind of drilling well.
Technical problem solved by the invention mainly comprises that metal and macromolecular material are when hot insert combines, the control of temperature and time and the key points such as mode of the demoulding in the reasonable layout of operation, hot insert process.
The present invention realizes by the following method:
A drilling well PEEK wear resisting cylinder jacket, the neck bush that is installed in the polyether-ether-ketone material of external bushing inwall by metal external bushing and the hot inserting method of employing forms.
Further, the method for described hot insert specifically comprises the following steps:
A. by the outer surface roughing of metal external bushing, internal surface fine finishing;
B. metal shell lining is fixed on to the specified position of mould;
C. after mould and outer cylinder sheath are in place, PEEK powder is injected in die cavity, then compression molding, molding temperature is 380 ℃-390 ℃, clamp time is 4-5 hour;
D. mould is removed, after treating that workpiece recovers normal temperature, workpiece is carried out to mechanical process; Described processing is processed, in field of machining or acceptable any one processing technology of other processing technology;
E. internal surface is refined to and requires size, require surperficial cylindricity and degree of finish to reach requirement.
Described metal material is carbon steel.
Preferably, described metal material is carbon steel.
Beneficial effect: adopt that the present invention makes PEEK wear resisting cylinder jacket good in the trial state of each elephant, Novel cylinder jacket has completed many wells time on-site assessment, surpass 750h average life, it should be noted that, this index of aging has surpassed Foreign Advanced Lerel; The cost of production of integral cylinder liner has obtained good optimization, and cost per unit bi-metal liner has before declined 20%, has significantly saved cost.Because neck bush adopts PEEK material, therefore the PEEK wear resisting cylinder jacket of producing more renews neck bush conveniently, after neck bush lost efficacy and scraps, more thorough when cleaning is changed.On the other hand, the success rate of the wear-resisting steel bushing processing of PEEK is very high.
Accompanying drawing explanation
The present invention has accompanying drawing 1 width.Fig. 1 is the PEEK wear resisting cylinder jacket sectional view for drilling well that the present invention produces.
In the drawings, 1-external bushing; 2-neck bush.
