Abstract
The invention discloses a method for manufacturing screw pump and screw motor stator with composite material, firstly jacketing unvulcanized rubber tube on a mould core and heating and pressurizing them in a pressurizer into rubber lining, then jacketing the lining on the mould core and coating adhesive on the outer surface of the lining, then winding and coiling with fiber reinforced material to make stator preform, placing the stator perform into a casing for vacuum-pressure injection of liquid resin to make a stator whole, then making resin curing and rubber sulfuration and finally cooling and demoulding. And the made screw pump and screw motor stator has features of high single stage head, high efficiency, wearable and anticorrosive, and low manufacturing cost and exchangeable.
Description
Technical field: the present invention relates to a kind of screw pump and screw motor stator, relate in particular to a kind of screw pump that is used for petroleum production and drilling well and screw motor stator with the composite material manufacturing.
Background technique: the screw pump that petroleum production at present and drilling well are used and the stator liner of screw motor (helicoid hydraulic motor) are made by rubber, the distribution of the elastomeric thickness of stator liner on the major and minor axis of its molded lines is uneven, because the elastomeric wall thickness such as non-of existing screw pump and screw motor stator, make it have following shortcoming and defect: one, the single-stage pressure head of screw pump and the single-stage bearing capacity of screw motor are low, this is because the non-uniform thickness on the rubber bushing cross section causes, different its compress variations of the thickness of rubber are also different, therefore will produce leakage under the differential pressure action of pump stage two ends.Two, the non-uniform thickness of rubber bushing is easy to cause the tired heating of rubber to make rubber bushing aging in advance.Three, screw pump and the screw motor efficient made from existing stator is low, and this is because the inhomogeneous stator molded lines that makes of swelling of rubber bushing changes under the erosion of the gentle oil well hydrocarbon of well.Four, manufacture cost height because the non-wall thickness that waits of existing stator rubber lining, makes that to make the needed rubber mass of stator bigger, therefore in ceiling price system the use of high-grade rubber.Five, the poor dimensional stability of existing stator rubber lining, size can differ from half millimeter more than under different downhole temperatures, and this will cause the hydraulic characteristic generation great variety of screw pump or screw motor.Six, stator non-interchangeability makes and can't be consistent on the rubber bushing size because the injecting glue pressure and temperature is difficult to control.
Summary of the invention: the objective of the invention is: provide a kind of screw pump and screw motor stator with the composite material manufacturing to make its rubber elastomer that wall thickness such as has overcoming all deficiencies of prior art, not only single-stage pressure head height, efficient height but also dimensional stability are good and have good interchangeability for it.Another object of the present invention is to use high-grade rubber to do stator liner under the situation that does not increase the stator manufacture cost, makes stator have better heat-resisting quantity, wear resistance and corrosion resistance.One purpose of the present invention provides a kind of screw pump and screw motor stator with the composite material manufacturing and makes it not only can be used for oil mining and drilling well but also can be used for ground other industrial fields.Purpose of the present invention also will provide the manufacture method of making this screw pump and screw motor stator.
For realizing above-mentioned goal of the invention, the present invention improves material and the method for manufacturing technology of making screw pump and screw motor stator.The manufacturing process of making this stator can be divided into four processes: the elastomeric bushing of 1, making ribbon line.2, lining is placed on the core rod in its appearance spraying adhesive and twines fibre reinforced materials.3, the core rod that will twine the good fiber reinforcing material is put into the housing of pump or motor, and the two ends shutoff vacuumizes then, and under pressure liquid resin is injected and fill up in the chamber of fiber.4, at last stator is put into heating equipment and carried out the resin solidification and the vulcanization of rubber.
In order to make the elastomeric bushing of ribbon line, at first prepare the thin-walled rubber tube of uncured, the internal diameter of tube equals the core rod long axis length, and the wall thickness of tube should be greater than 3mm.With rubber sleeve in hollow spray on the stator mould of releasing agent, need to prove that each recess of film tool molded lines is drilled with vent hole, vent hole is communicated with the hollow hole of mould.Rubber sleeve on core rod after the two ends of two ends and core rod fix, make exocoel formation gas seal in the rubber tube, the core rod that will have rubber tube then is placed in the heatable pressurizing vessel, the two ends of film core and container two ends all have seal arrangement is isolated from the outside container intracavity, the hollow hole of core rod and atmosphere are communicated with, container is heated to 60-120 ℃ to pressurize in container with air pump, rubber tube will be attached on the core rod and form the molded lines of core rod, take out from container then, the cooling back demoulding has just formed the rubber bushing that has molded lines.Preferably rubber bushing is made pipe nipple for easy to make.
When making stator, the lining pipe nipple is enclosed within on the long core rod of identical molded lines, and will connects to meet and glue.Next at rubber bushing outer surface coated with adhesive, treat to twine the Hand of spiral winding of yarn with glass fibre after the Bond drying along core rod, the recess of lining is filled up, also the usable fibers woven roving is filled recess, but woven roving must be cut into suitable width and be rolled into the cylindrical rope that twists into, recess fills up back reprocess fibre woven roving and carries out the circumference winding, and the stator precast body diameter after the winding should be slightly less than the stator case internal diameter.Then the stator precast body is placed in the stator case, two ends seal with plug.Vacuumize then, and under pressure, the liquid resin injection is filled up in the chamber of fiber.Next stator is put into heating equipment and carry out the resin solidification and the vulcanization of rubber.Cooling and demolding had just obtained the finished product stator after sulfuration was finished.
Also can otherwise make the stator precast body, thickness is cut into wide 50-80mm rubber bar greater than the sheet rubber of the uncured of 2mm, its pressure that changes is wrapped on the core rod of heating, then at its outer surface coated with adhesive, treat the recess of core rod to be filled and led up with fibre reinforced materials by preceding method again after the Bond drying, reprocess fibre woven roving circumference twines, and down manufacturing process and preceding method are identical.
Fibre reinforced materials can be glass fibre, carbon fiber, steel fiber and synthetic fiber.The liquid resin that is used for vacuum-pressure injection can be unsaturated polyester resin, epoxy resin and vinyl ester resin.The material of making rubber bushing can be nitrile butadiene rubber, butyl rubber and hydrogenated nitrile-butadiene rubber.
Use the screw pump of above-mentioned material and method manufacturing and screw motor stator not only single-stage pressure head height, efficient is high and resistance to wear, ageing-resistant, also have low cost of manufacture and interchangeable characteristics simultaneously.
