Description
The utility model relates to the fluid end parts of reciprocating pump.
After the oil recovery of each elephant enters middle and advanced stage, all water filling in oil well is generally promoted as the important measures of high and stable yields, the capital equipment of water filling is reciprocating type high pressure water-injection pump in oil well, its structure comprises two-part, a part is a fluid end, and another part is a power end, and the effect of fluid end is to carry liquid, mechanical energy is converted to the pressure energy of liquid, is the working portion of reciprocating type high pressure water-injection pump.At present, the reciprocating type high pressure water injection pump hydraulic end that use in the oil field all is to adopt the integrated type liquid cylinder, is about to 3-5 cylinder and makes as a wholely, therefore, has following deficiency; 1, after one of them cylinder damages, just must change whole liquid cylinder, unspoiled cylinder is together changed in company with the cylinder that damages, thereby causes great waste; 2, big, the Heavy Weight of volume must be used lifting device during replacing, and is very inconvenient.
The purpose of this utility model is the separate split type reciprocating type high pressure water injection pump hydraulic end of a kind of each cylinder of design.
This reciprocating type high pressure water injection pump hydraulic end comprises connecting plate, sealing and fixing has stuffing box packing case side by side on an end face of connecting plate, one plunger is housed in the inner chamber of each stuffing box packing case, be set with the stuffing box packing pad on the plunger, the stuffing box packing pad is fastening by gland, the end of plunger stretches on the connecting plate in the corresponding plunger hole, its structural feature is that sealing and fixing has side by side fluid cylinder on the other end of connecting plate, the quantity of fluid cylinder is corresponding with the quantity and the mounting point of plunger with the mounting point, the fixed block of liquid suction valve group and liquid suction valve group is housed in the inner chamber of each fluid cylinder, and on the cylinder body of each fluid cylinder, be provided with the feed liquor tube chamber that is communicated with inner chamber, sealing and fixing has and sucks flow piece and the discharge piece that confluxes on the exterior edge face of fluid cylinder, the tube chamber that sucks on the flow piece is communicated with the feed liquor tube chamber, the tube chamber that discharge is confluxed on the piece is communicated with the inner chamber of fluid cylinder, and fixed block is fixed on discharges on the piece that confluxes.
Above-mentioned liquid suction valve group comprises valve seat, be provided with sap cavity from liquid feeding end in the valve seat, the outlet end of valve seat is evenly equipped with the liquid outlet opening that is communicated with sap cavity, the scrobicular ring that is not communicated with on the side of valve seat with the feed liquor tube chamber, an O RunddichtringO that makes the internal surface sealing of valve seat and fluid cylinder is respectively adorned in the both sides of scrobicular ring, the valve seat liquid feeding end is evenly equipped with the inlet opening that is communicated with scrobicular ring, be equipped with at the liquid feeding end of valve seat and be the ladder barrel shape and the bottom surface can be with the suction valve disc of inlet opening sealing, inhalation valve spring is housed in the suction valve disc, outlet end at valve seat is equipped with discharge valve block fixing by the expulsion valve spring and that liquid outlet opening can be sealed, the expulsion valve spring is contained on the spring seat, and spring seat is by the outlet end that is bolted to valve seat.
Above-mentioned reciprocating type high pressure water injection pump hydraulic end is connected with the body of plunger pump by connecting plate in use.Its working procedure is; Plunger retreats to the body direction, the plunger hole on the connecting plate, and the chamber pressure of suction valve disc and valve seat reduces, and this pressure is less than the fluid pressure that sucks in tube chamber and the inlet opening, and suction valve disc is opened, and liquid enters the inner chamber of plunger hole, suction valve disc and valve seat.Plunger is to advancing in the other direction, plunger hole, fluid pressure in the inner chamber of suction valve disc and valve seat increases, under the effect of inhalation valve spring, suction valve disc stops up inlet opening, and the discharge valve block that stops up liquid outlet opening is opened, liquid enters the tube chamber of discharging on the piece that confluxes, plunger halts, and under the effect of expulsion valve spring, discharges valve block and again liquid outlet opening is stopped up.Above-mentioned feed liquor, discharge opeing process move in circles, and finish the function of pumping liquid.
Because each fluid cylinder of this reciprocating type high pressure water injection pump hydraulic end is installed on the connecting plate abreast, the fixed block of liquid suction valve group and liquid suction valve group is housed in the inner chamber of each fluid cylinder, each fluid cylinder is separate, after one of them fluid cylinder damages, only needs to change the fluid cylinder that damages, remaining fluid cylinder needn't be changed, thereby avoided changing the waste that whole fluid cylinders cause, because single fluid cylinder volume is little, in light weight, do not need lifting device during replacing, easily.Also owing to suction valve and expulsion valve horizontal arrangement, a shared valve seat with the sealing of O RunddichtringO, thereby is convenient to maintenance.
