Abstract
This invention relates to one column pump bus suitable for oil well injection and pump operation, wherein, the pump bus is composed of column piston, main part, sealed part, flow-in valve and exit valve. The common piston head bus solves the friction heat problem and adopts pump liquid cooling from sealed disc root and adopts outside oil or water for cooling. In order to adapt for oil well Pump operation, the invention discloses one new column pump bus.
Description
The present invention relates to a kind of plunger pump pump head assembly, be applicable to that oil-field flooding is applicable to that more oil field transfer drive profile control liquid pump goes into construction.
The total Chengdu of plunger pump pump head is made up of plunger, letter body, sealing, feed liquor valve, liquid discharging valve.Conventional plunger pump pump head assembly generally adopts and pumps into liquid cooling but from what sealed packing oozed out when solving plunger and packing frictional heating, adopts sometimes to add machine oil or water cycle cooling.But when these plunger pumps are used for the profile control construction,,, shortened sealing life so sealed packing is damaged greatly because cooling effectiveness is low and pump into liquid-solid phase granule content height.In order to adapt to the construction that pumps into of oil field profile control profile control agent, the spy has developed a kind of pump head assembly of plunger pump.
Below in conjunction with accompanying drawing the present invention is described further:
Figure: plunger pump pump head assembly structure schematic representation of the present invention;
This assembly external form is a cylindrical body, is divided into low pressure letter body assembly, high pressure letter body assembly two-part (as figure), and two-part are connected with top seal circle 7 by fixing bolt 6 and are fixed on the casing of pump.Low pressure letter body assembly comprises pressure cap 1, low pressure letter body 2, low pressure-conducting disk root 3, baffle ring 4, low-pressure plunger 5, low-pressure plunger one end and the screwed connection of pump crankcase pull bar.The packing pressure cap links to each other with the letter body by screw thread, screws pressure cap 1 and can promote baffle ring and compress packing, and the packing distortion forms motive sealing with plunger surface.High pressure letter body assembly comprises high pressure letter body 8, high pressure-conducting disk root 9, regulates baffle ring 10, liquid discharging valve 11, preloading spring 12, silently 13, drive water hole 14, osculum 15 on the high pressure letter body into, high-pressure column is plugged with center liquid pass hole 16, and also perforate is corresponding with the water inlet, high-pressure plunger one end has feed liquor valve 17, and the other end links to each other with the low-pressure plunger screw thread.
This assembly is connected with top seal circle 7 by fixing bolt 6 and is fixed on the casing of pump, low-pressure plunger one end and pump crankcase pull bar with screwed connection good after, the motor of primer pump, bent axle drive plunger and move reciprocatingly.When plunger during to left movement, liquid discharging valve 11 is closed, and feed liquor valve 17 is opened, the low pressure that pumping liquid produces by the high-pressure plunger top make profile control liquid by the water inlet through plunger perforate, center liquid pass hole, feed liquor valve, enter by the chamber of regulating the baffle ring trap in; The feed liquor valve cuts out when plunger moves right, and adjusting baffle ring inner chamber liquid pressurized backs down liquid discharging valve and discharges through osculum.Along with the to-and-fro motion of plunger, liquid constantly by the water inlet pump to osculum.When the water inlet links to each other with profile control liquid dosing pond, osculum links to each other with water injection well, just can realize that the profile control liquid pump goes into construction.
The peculiar function introduction of this assembly is as follows: the normal conditions lower plunger motive sealing as the low pressure letter body portion structure in this assembly, adopt the sealing of external pressure compact form, screw pressure cap 1 and can promote baffle ring and compress packing, the packing distortion forms motive sealing with plunger surface.And the motive sealing of this assembly high-pressure plunger is to be delivered on the high pressure-conducting disk root through liquid discharging valve steel body, adjusting baffle ring by the preloading spring active force, packing is tentatively compressed produce sealing just.When plunger be subjected to after liquid discharging valve is closed during to left movement the high pressure liquid effect left impacting force act on the packing through regulating baffle ring, form better sealing effect; When plunger moved right, the high pressure liquid that plunger top produces acted on packing and regulates on the surface of contact of baffle ring, forms better sealing effect.The fricative heat of plunger and packing is taken away by the working fluid of center liquid pass hole, thereby has realized the efficient cooling of the non-leakage situation lower plunger of packing_seal.
The normal conditions lower plunger is from range point during to swivel motion, owing to be subjected to the expansibility influence of compressibility materials such as gas, the feed liquor valve can not be opened immediately, has influenced the full level of pump, thereby has reduced pump efficiency.This total composition low-pressure plunger and high-pressure plunger, if change the low-pressure plunger size, make the low-pressure plunger diameter less than the high-pressure plunger diameter, and install auxiliary feed liquor valve 18 additional at water intake, when plunger moves reciprocatingly, constantly change because the endoceliac plunger segment body of letter between low pressure seal and high pressure sealing is long-pending, form auxiliary feed liquor function, improved pump efficiency.
Sum up the advantage of this assembly: 1, adopt the hollow plunger feed liquor to solve heat dissipation problem, it is watertight that motive sealing has been accomplished.2, adopt packing to tighten mechanism automatically, termination of pumping when having avoided tight packing pressure cap.3, adopt split type single plunger pump head assembly, be convenient to processing and change the situation of having avoided the bad sealing surface of the whole pump head thorn of original three plunger water injection pumps just to change.4, adopt plunger feed liquor valve, line layout design of liquid discharging valve, saved the space, be convenient to maintenance.5, can utilize auxiliary feed liquor valve to improve pump efficiency.
