Abstract
A high-pressure pump connecting pipe for oil field deep well features that it has vibration damping, noise absorbing and ultrahigh pressure bearing functions. The utility model discloses technical essential: the corrugated pipe is provided with a double-layer thin-wall S-shaped corrugated pipe, a wave valley inner armored non-metal vibration reduction ring, a semi-soft light-drawing thick steel wire woven double-layer net sleeve and a special outer sheath. The utility model has the advantages of reinforce damping and damping effect, noise when reducing the vibration, the mutual excitation of separation multi-pump piping has improved instrument and pump life. And can form a series, is beneficial to popularization and implementation and has great social benefit.
Description
The utility model provides a kind of novel high-pressure service pump piping device, is applicable to oil-field flooding, boiler water supply, the contour press pump import and export pump connecting leg device of pressure processing machinery.Recover the oil especially for the oil field deep well high pressure water injection, have vibration damping and inhale the high-pressure service pump connecting leg of making an uproar and can bear ultrahigh pressure.
Because general bellows or metallic hose can not bear high pressure and high vibrational loading.Industrial both at home and abroad at present being used for still adopts steel pipe directly to connect on the high-pressure service pump import and export piping usually, its vibration, noise are all very big, cause pipeline to extrude especially that piping instrument, valve are damaged, service cycle is frequent, welding bead leaks, the pump life-span is low, have a strong impact on the ordinary production operation, become this technical field hard nut to crack at present.
The utility model purpose is to have technical barrier for more than solving, and a kind of new structure high-pressure service pump connecting leg is provided.Can improve the bellows bearing capacity, realize absorbing multidirectional vibration, have the vibration damping of reinforcement and damping function, noise when reducing vibration, and can in many pumps composition pipelines, intercept mutual exciting between pump, improve the working life of instrument and pump, can effectively prevent the advantages such as harm that high-pressure liquid caused the people when welded tube leaked.
The utility model is achieved in that the high-pressure service pump connecting leg is made of bellows, damping ring, net, adapter, retaining ring, oversheath, bend pipe etc.It is below main structure feature:
1, has the double-deck S type of thin-walled bellows and reduce its bellows stiffness raising flexibility, adopt two sections positive body structures of same structure dictyosome L type to absorb multidirectional vibration; 2, set up nonmetal damping ring in the bellows trough, strengthen bellows and bear interior pressure energy power and absorb vibrational energy reduction noise; 3, adopt the good medium-soft attitude of tensile strength gently to draw the double-deck net of heavy wire and silk ribbon braiding; 4, oversheath can absorb and leak the high energy medium people's harm is had special protective action.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 1, high-pressure service pump connecting leg structural representation (table number is in related description).
Below in conjunction with Fig. 1 technical characteristics of the present utility model is further described:
(0.4～1mm) corrosion resistant plate one-time continuous is pressed into S type bellows to bellows (1), and outside diameter of bel is below the 80mm in this example, and the interlayer gap is 0.3～0.5mm, and briquetting pressure is 19MPa by double-layer thin wall; Bellows (1) S type trough inner armor has damping ring (3), and the polyamine fat glue that nonmetal damping ring is made of special formulation and nylon bundle silk twine a few and solidify at normal temperatures and form, its strengthen bellows bear in pressure energy power and absorption vibrational energy; The outer employing of bellows (1) has certain tensile strength (6 b70-83) 1.2mm medium-soft attitude and gently draws heavy wire and silk ribbon to be woven into double-deck net (2), improves damping and vibration absorption ability; Bellows (1) is integrally welded with adapter (5); The outer oversheath (4) that is equipped with of bellows (1) and net (2), oversheath (4) adopts thin-wall stainless steel to twine double-deck flannelette cover outward, can absorb the high energy medium that the spray of piping Leak hole is shown, to prevent harm to the people, take over (5) front end and oversheath (4) welding, and retaining ring (7) is housed welds fastening; The bellows dictyosome is by bellows (1), net (2) damping ring (3) oversheath (4) is taken over (5), retaining ring compositions such as (7), the bellows dictyosome that two-stage structure is identical adopts the positive body structure of L type, be weldingly connected by bend pipe (6), realized the utlity model has vibration damping and inhaled the high-pressure service pump connecting leg of making an uproar and can bear ultrahigh pressure.
The high-pressure service pump connecting leg can take straight tube welding or slips joint to be connected with the interface mode of oil field deep well high-pressure service pump.The position is sewed in its straight tube welding manner compact structure, minimizing; The slips joint connects its easy accessibility, sealing is reliable, respectively has its advantage to select for the user needs.
Claims (4)
1, a kind of novel high-pressure pump connecting leg, be made up of bellows (1), joint (5), bend pipe (6), retaining ring (7) etc., it is characterized in that: bellows (1) adopts double-layer thin wall, and (0.4～1mm) corrosion resistant plate one-time continuous is pressed into its two ends welding of S type bellows and takes over (5); Bellows (1) trough inner armor has damping ring (3); Bellows (1) skin has double-deck net (2) and oversheath (4), constitutes the bellows dictyosome.
2, according to the described high-pressure service pump connecting leg of claim 1, it is characterized in that: damping ring (3) adopt special formulation polyamine fat glue and the winding of nylon bundle silk a few solidify at normal temperatures and form; Double-deck net (2) adopts the medium-soft attitude gently to draw heavy wire and silk ribbon braiding to form; Oversheath (4) adopts thin-wall stainless steel outer around double-deck flannelette cover; Bellows dictyosome two ends are closed up fastening with retaining ring (7) welding with special frock.
3, according to claim 1,2 described high-pressure service pump connecting legs, it is characterized in that: the identical ripple pipe network of two-stage structure body and function bend pipe (6) connects, and realizes absorbing multidirectional vibration with the positive body structure of L type.
4, can have according to the interface of the high-pressure service pump connecting leg of claim 3 and select to adopt straight tube welding and slips joint Placement.
