Abstract
A kind of drilling well PEEK wear resisting cylinder jacket and hot inserting method thereof, by the outer surface roughing of metal external bushing, internal surface fine finishing; Metal shell lining is fixed on the specified position of mould; After mould and outer cylinder sheath are in place, injected by PEEK powder in die cavity, then compression molding, molding temperature is 380 DEG C-390 DEG C, and clamp time is 4-5 hour; Mould is removed, after treating that workpiece recovers normal temperature, mechanical process is carried out to workpiece; Internal surface is refined to and requires size, require that surperficial cylindricity and degree of finish reach requirement.Described metal material is carbon steel.PEEK wear resisting cylinder jacket average life that the present invention makes, it should be noted that, this index of aging exceeded Foreign Advanced Lerel more than 750h; The cost of production of integral cylinder liner obtains good optimization, cost per unit comparatively before bi-metal liner have dropped 20%, significantly saved cost.<!-- 2 -->
Description
Technical field
The invention belongs to the manufacture method of the main easily damaged parts of drilling pump, especially a kind of drilling well PEEK wear resisting cylinder jacket and hot inserting method thereof.
Background technique
At present, the cylinder sleeve majority of each oil field drilling pump used is bi-metal liner, and neck bush employing centrifugal pressure casting, the rich chromium cast iron that wear resistance is very high are made.Due to inside and outside cover employing is interference fit, after cylinder sleeve uses wear out failure, if want, neck bush is extruded, more renews neck bush comparatively difficult, therefore, after neck bush inefficacy is scrapped, must change in the lump by inside and outside lining.So, when external bushing do not damage just scrap, add suitable expense to complete equipment.Learn according to investigation, such cylinder sleeve every average life is at about 500h.Annual national oil field needs to consume several ten thousand, causes great waste.
Summary of the invention
The object of the invention is for current domestic existing cylinder sleeve of drilling pump cost high, the not easily changeable problem of neck bush, provides a kind of drilling well PEEK wear resisting cylinder jacket and hot inserting method thereof.
Technical problem solved by the invention mainly comprises metal and macromolecular material when hot insert combines, the key point such as the control of temperature and time and the mode of the demoulding in the reasonable layout of operation, hot insert process.
The present invention realizes by the following method:
A kind of drilling well PEEK wear resisting cylinder jacket, the neck bush being 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 the specified position of mould;
C., after mould and outer cylinder sheath are in place, injected by PEEK powder in die cavity, then compression molding, molding temperature is 380 DEG C-390 DEG C, and clamp time is 4-5 hour;
D. mould is removed, after treating that workpiece recovers normal temperature, mechanical process is carried out to workpiece; Described processing process, in field of machining or other processing technology any one processing technology acceptable;
E. internal surface is refined to and requires size, require that surperficial cylindricity and degree of finish reach requirement.
Described metal material is carbon steel.
Preferably, described metal material is carbon steel.
Beneficial effect: adopt the present invention make PEEK wear resisting cylinder jacket good in the trial state of each elephant, Novel cylinder jacket completes many wells time on-site assessment, average life, more than 750h, it should be noted that, this index of aging exceedes Foreign Advanced Lerel; The cost of production of integral cylinder liner obtains good optimization, cost per unit comparatively before bi-metal liner have dropped 20%, significantly saved cost.Because neck bush adopts PEEK material, therefore the PEEK wear resisting cylinder jacket produced 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 PEEK wear-resisting steel bushing processing is very high.
Accompanying drawing explanation
The present invention has accompanying drawing 1 width.Fig. 1 is the drilling well PEEK wear resisting cylinder jacket sectional view that the present invention produces.
In the drawings, 1-external bushing; 2-neck bush.
Embodiment
By the outer surface roughing of metal external bushing, internal surface fine finishing; Metal shell lining is fixed on the specified position of mould; After mould and outer cylinder sheath are in place, injected by PEEK powder in die cavity, then compression molding, molding temperature is 380 DEG C-390 DEG C, and clamp time is 4-5 hour; Mould is removed, after treating that workpiece recovers normal temperature, mechanical process is carried out to workpiece; Described processing process, in field of machining or other processing technology any one processing technology acceptable; Internal surface is refined to and requires size, require that surperficial cylindricity and degree of finish reach requirement.Described metal material is carbon steel.
