Description
Technical field
The utility model relates to a kind of pumping equipment that advances, and being that a kind of high pressure reciprocating pump is multi-functional specifically advances pumping equipment.
Background technique
The plunger type high-pressure reciprocating pump of extensive use in the petroleum chemical industry, it advances the structural type and the work system of pumping equipment, the change of essence is not arranged for many years, be cartridge type valve arrangement or flap type structure always, these two kinds of structures, not only cause the overcurrent liquid communication to have some setbacks easily, served as flow liquid body viscosity easy quiet knot when excessive, and the sealing anchor ring of spool and valve seat, the one, area of contact is too little, the 2nd, can not realize complete surface hardness processing, when being applied in the mining area, oil field, because long-time continuous running work, the sealing anchor ring of spool and valve seat per hour will bear 10,000 times-30,000 times bump, very easily be out of shape and wear and tear, can not play seal action, working life is short, when working pressure is no more than 20MPa, be 20-30 days the working life of every cover combination valve, annotate Polyacrylamide or annotate sodium silicate when being used for the down-hole, surface active agent, when polymer and other were corrosive soda acid liquid, both increased labor intensity no longer than 10 days working life, strengthen cost of production, reduced oil production rate again.
Summary of the invention
The purpose of this utility model provides that a kind of high pressure reciprocating pump of long service life is multi-functional to advance pumping equipment.
For realizing above-mentioned purpose, this high pressure reciprocating pump is multi-functional to advance pumping equipment, comprise pump head body, pump head body is provided with the plunger hole of inlet opening, liquid outlet opening and installation plunger, its structural feature is that pump head body is provided with endoporus, and one group of valve assembly is housed in each endoporus, and each group valve assembly comprises a feed liquor valve, liquid valve and a hold-down mechanism, the structure of feed liquor valve and liquid valve is identical, all is ball formula seal valve.
As to the multi-functional improvement of advancing pumping equipment of this high pressure reciprocating pump, between the feed liquor valve of every group of valve assembly and liquid valve, setting sleeve is housed.
Above-mentioned ball formula seal valve comprises valve seat, valve seat is provided with the liquid entering hole that is communicated with valve base cavity, the intracavity bottom of valve seat is equipped with ball seat, ball seat and valve seat interference fit, the ball that one highi degree of accuracy, high hardness is housed on the ball seat and can rotates, the surface of contact precise finish of ball seat and ball also seals with ball, be crimped with spring between the top of ball and the spring capping, on the spring capping of feed liquor valve, be provided with liquid outlet opening, the liquid entering hole of feed liquor valve is communicated with inlet opening, the valve seat of liquid valve is provided with outage, and the liquid entering hole of liquid valve is communicated with plunger hole.
The quantity of above-mentioned pump head body endoporus is 2-4, preferably 3.
Above-mentioned spring is contained in the spring seat, and spring seat is provided with relief hole, and wherein the spring seat of feed liquor valve and the gap between the valve seat are fluid passage.
Above-mentioned hold-down mechanism comprises that silently an end silently is plugged in the endoporus, the other end is connected with pressing plate.
The multi-functional working procedure of advancing pumping equipment of this high pressure reciprocating pump is: after high pressure reciprocating pump started, plunger was reciprocating in plunger hole under the drive of bent axle.When plunger when plunger hole retreats, because the pumping action of vacuum, the ball of liquid valve and ball seat sealing, and overcoming the pressure of spring, the ball of feed liquor valve moves upward, the liquid outlet opening of liquid on the liquid entering hole on the inlet opening on the pump head body, the feed liquor valve base, valve base cavity, spring capping, enter the setting sleeve inner chamber, be full of all spaces.When plunger when plunger hole advances, on the one hand under the acting in conjunction that the spring reset in pressure and feed liquor valve promotes, ball in the feed liquor valve falls, seal with ball seat, ball in the liquid valve pressure that promotes to overcome spring that is stressed moves upward on the other hand, and liquid flows out by the outage on the liquid valve valve seat, the liquid outlet opening on the pump head body rapidly.Above-mentioned process is gone round and begun again, and realizes the discharge opeing of advancing of high pressure reciprocating pump.
This high pressure reciprocating pump is multi-functional to advance pumping equipment, owing to adopted ball formula seal valve, compare with the flap type structure with original cartridge type valve arrangement, the one, strengthened sealing area, the 2nd, ball can rotate, the position of conversion sealing surface, reduce sphere abrasion, the 3rd, ball and ball seat are selected high hardness for use, wear-resistant, impact-resistant materials processing becomes high-precision sealing surface, its beneficial effect is: 1, long service life in working pressure is the scope of 25MPa-40MPa, can reach 100 days working life-200 days, improve 5-10 doubly, working pressure reaches as high as 45MPa, improve 2 times; 2, can be used for the various thick liquids of transport viscosity in the 5000MPs-8000MPs scope; 3, applied range is applicable to the down-hole of water, Polyacrylamide, sodium silicate, surface active agent, polymer and other soda acid liquid that is corrosive is injected; 4, ball in feed liquor valve and the liquid valve and valve seat can be changed, and have prolonged whole working life of advancing pumping equipment, have reduced cost of equipment.
