Abstract
An anticorrosion antiwear oil-well pump for mechanical oil extraction features that a combined pump cylinder consisting of metal cylinder sleeve and composite bush made of metal and ceramic or other hard material is installed in external cylinder at intervals, and a valve seat made of metal and ceramic or other hard material is matched with ceramic valve ball. The composite bushing of the oil well pump protects the strengthening layer or the anticorrosive layer on the inner surface of the metal cylinder sleeve in the continuous friction motion process of the pump cylinder and the plunger, reduces the abrasion speed of the pump cylinder, prolongs the service life of the oil well pump, has low cost and is suitable for mass popularization.
Description
The utility model belongs to the oil well pump that uses in the oil well.
The application number of Patent Office of the People's Republic of China's bulletin on January 30th, 1991 is that 90216983.1 patents have been announced a kind of oil well pump that adopts ceramic cylinder jacket to replace Metallic cylinder, because general stupalith intensity and toughness can not satisfy oil well pump transportation and usage requirement, have only engineering ceramics (as the PSZ pottery) just to exempt from available by force.And engineering ceramics cost height, difficulty of processing is big, makes the ceramic cylinder jacket oil well pump cost an arm and a leg, and is difficult to apply.
The purpose of this utility model is to provide a kind of wearability and corrosion resistance all obviously to be better than conventional oil well pump, and cost significantly is lower than the novel oil well pump of ceramic cylinder jacket oil well pump, and be more than 2 times of conventional oil well pump its working life.
The purpose of this utility model is achieved in that in the oil well pump urceolus, the composite bush of packing Metallic cylinder into and made by metal and corrosion-proof wear-resistant material in the interval, and valve seat is made by metal and corrosion-proof wear-resistant material.
The purpose of this utility model can also reach like this: the composite bush of corrosion-resistant wear-resistant oil pump is made by the damascene corrosion-proof wear-resistant material, and corrosion-proof wear-resistant material is pottery or other hard material.Composite bush also can be to be inlayed to overlap in the anticorrosion antiwear by metal-coating to make, and it can also be by bonding the forming of cover in metal-coating and the anticorrosion antiwear, and cover is by pottery or the manufacturing of other hard material in the anticorrosion antiwear.The valve seat of corrosion-resistant wear-resistant oil pump is manufactured by the damascene corrosion-proof wear-resistant material, corrosion-proof wear-resistant material is pottery or other hard material, valve seat also can be inlayed to encircle in the anticorrosion antiwear and form by the metal outer shroud, it can also be by bonding the making of ring in metal outer shroud and the anticorrosion antiwear, and ring is made by pottery or other hard material in the anticorrosion antiwear.
Accompanying drawing is a sectional front view of the present utility model.
Be described further below in conjunction with accompanying drawing.
As accompanying drawing, in urceolus 3, pack at interval Metallic cylinder 8 and composite bush 4, two ends compress and are fixed on pressed joint 2 and 9 forms the combination pump barrel on the urceolus 3, on the pressed joint 9 of combination pump barrel, connect standing valve cover 10, with fixed valve ball 11 and valve seat 12 usefulness joints, 13 connections and be pressed in the standing valve cover 10.Oil pump plunger piston is formed in the lower end that valve ball 5 and valve seat 6 usefulness joints 7 are fixed on the plunger body 1 that has internal thread of moving about, and plunger is packed into form corrosion-resistant wear-resistant oil pump in the combination pump barrel.Because the combination pump barrel is to be combined into by composite bush and Metallic cylinder; plunger is in upper and lower fricting movement process; plural composite bush and plunger contact friction have been remained; composite bush internal wall ceramic material is not only wear-resisting but also against corrosion; thereby protected Metallic cylinder internal surface wearing layer or anticorrosive coat not to be subjected to plunger wear; slow down the pump barrel rate of wear, improved the wear resistance and corrosion resistance of pump barrel.Overlap inserted in the anticorrosion antiwear that composite bush adopts metal-coating and pottery to make, solved the problem that carrying that ceramic cylinder jacket impact resistance difference causes damages, valve seat be subjected to encircle in the ceramic embedded anticorrosion antiwear of making of erosion surface, join ceramic valve ball, improved the operating life of valve greatly.
The ceramic fitting of the utility model oil well pump, sufficient raw, machinability is better, particularly adopts inserted composite bush, greatly reduces the stupalith consumption, thereby has reduced the oil well pump cost.Oil well pump of the present utility model can be applicable on the pumping well of any degree of depth.Oil well pump long service life of the present utility model reduces and changes pump well workover number of times, reduces cost for oil production, improves crude output.
