Fig. 1 is the sectional view of oil well deep oil well pump of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of oil well deep oil well pump, it comprises outer working tube 1, pull bar 2 and deaerator 3, wherein: in outer working tube 1, be equipped with interior working barrel 4, multiple righting block 11 is in axial direction connected with between described interior working barrel 4 and described outer working tube 1, the lower end of described interior working barrel 4 is connected with standing valve 5, and described standing valve 5 is connected with the lower end of described outer working tube 1; Pull bar 2 is located in described outer working tube 1, and the lower end of described pull bar 2 is connected with plunger 21, and described plunger 21 is located in described interior working barrel 4, and the lower end of described plunger 21 is connected with traveling valve 6; Deaerator 3 is connected to the lower end of described standing valve 5.
Specifically; outer working tube 1 is substantially in cylindrical tube shape; interior working barrel 4 is equipped with in it; interior working barrel 4 is connected on the madial wall of outer working tube 1 by the righting block 11 that multiple axially spaced-apart is arranged; in the present embodiment; interior working barrel 4 is made up of the protection cylinder 41 that about two are connected, and protection cylinder 41 cylindrically, is protected between two between cylinder 41 and is connected by box cupling 42.
Plunger 21 is substantially in cylindrical tube shape, its upper end is connected with plunger valve bonnet 211, this plunger valve bonnet 211 is provided with multiple through hole (not shown), those through holes are connected with the hollow cavity 212 of plunger 21, pull bar 2 is connected with plunger valve bonnet 211, and the lower end of plunger 21 is connected with traveling valve 6.Plunger 21 is located in interior working barrel 4, Spielpassung between itself and interior working barrel 4, and plunger 21 axially can move down in interior working barrel 4, and the length of plunger 21 is greater than the length of interior working barrel 4.
Standing valve 5 has valve seat 51 and is arranged on the valve plug 52 on valve seat 51 opening or closing, and the upper end of valve seat 51 is connected with interior working barrel 4 with outer working tube 1 respectively.
Deaerator 3 has urceolus 31, and the upper end of urceolus 31 is connected with valve seat 51 lower end of standing valve 5, and the upper end sidewall of urceolus 31 offers air outlet hole 311, and the lower end sidewall of urceolus 31 offers oil inlet hole 312, and the madial wall of urceolus 31 is provided with helical groove 313.
The working procedure of this oil well deep oil well pump is as follows: when upstroke, the mutually internal working barrel 4 of plunger 21 moves upward, now the valve plug 52 of standing valve 5 lifts off a seat 51, standing valve 5 is opened, crude oil in oil reservoir enters in urceolus 31 by the oil inlet hole 312 on deaerator 3 urceolus 31, under the effect of the helical groove 313 of urceolus 31 madial wall, gas-liquid separation in crude oil, isolated gas is discharged through the air outlet hole 311 of urceolus 31, isolated liquid enters in interior working barrel 4 through standing valve 5, now, pressure in plunger 21 hollow cavity 212 is less than the pressure of plunger 21 inside, in this case, fluid column static pressure between interior working barrel 4 and outer working tube 1 in annular space acts on the outer wall of interior working barrel 4, under the effect of the pressure, gap between plunger 21 and interior working barrel 4 reduces, thus the pump efficiency reduction caused because of leakage can be reduced.When down stroke, the mutually internal working barrel 4 of plunger 21 moves downward, now traveling valve 6 is opened, liquid in interior working barrel 4 flows in the hollow cavity 212 of plunger 21 through traveling valve 6, and flow in interior annular space between working barrel 4 and outer working tube 1 by the multiple through holes on the plunger valve bonnet 211 of plunger 21 upper end, now, the hollow cavity 212 of plunger 21 is communicated with the annular space between interior working barrel 4 and outer working tube 1, interior working barrel 4 internal and external pressure balance, in this case, interior working barrel 4 is not stressed effect, and plunger 21 does not bear axial pressure, therefore swollen pump problem can be reduced.
Oil well deep oil well pump of the present utility model, is designed with sand control structure, and in also being shortened by adjustment plunger 21 length, working barrel 4 length is achieved.This oil well deep oil well pump remains that in movement process plunger 21 is longer than interior working barrel 4, its advantage by plunger valve bonnet 211, the sand containing crude oil of discharge is sunk under gravity, sink to the annular space between interior working barrel 4 and outer working tube 1, and can not be deposited between plunger 21 and interior working barrel 4, reduce and wear and tear because sand affects the plunger 21 caused, the problem that leakage increases.
In addition, oil well deep oil well pump of the present utility model, be designed with gas-tight structure, carry out Oil-gas Separation, after crude oil enters deaerator 3 by oil inlet hole 312 by setting up deaerator 3 in the lower end of standing valve 5, through the obstruct of helical groove 313, oil gas is done rotate, utilize centripetal force effect, make Oil-gas Separation, isolated gas discharges oil pipe through air outlet hole 311, to realize into the Oil-gas Separation before pump.
Further, oil well deep oil well pump of the present utility model, adopt double-barrel structure design, also in being, working barrel 4 and the structure of outer working tube 1, rationally improve the stress of interior working barrel 4 and outer working tube 1, the not swollen pump of working barrel 4 in realizing, extend the working life of pump, reduce operating frequency.
The foregoing is only several embodiment of the present utility model, those skilled in the art can carry out various change or modification to the utility model embodiment according to content disclosed in application documents and not depart from spirit and scope of the present utility model.
