Description
Technical field
The utility model relates to plunger pump technique field, more particularly to one kind for conveying liquid carbon dioxide and other
Hydraulic end of plunger pump containing gas medium.
Background technique
Plunger pump is that the common power convey to liquid carbon dioxide, liquid nitrogen, liquefied gas etc. containing gas medium is set
It is standby, for example, the oil field displacement of reservoir oil is handled up in technique or production using the essence of each animals and plants of carbon dioxide abstraction, require pair
Liquid carbon dioxide is conveyed, wherein handling up in technique in the oil field displacement of reservoir oil, by liquid carbon dioxide physical characteristic and fluid injection state
The influence of the particularity of carbon dioxide DP technology must have the requirement that can overcome gasification to the equipment of input.
Wherein, the oil field displacement of reservoir oil handle up technique be by reciprocating plunger pump be added mouth canned motor pump liquid carbon dioxide root
According to underground different pressure rating carry out injection reach handle up, oil displacement efficiency.It is generally used for Jie of storing liquid carbon dioxide
The pressure in matter source is 2.4-2.6Mpa, the entrance of plunger pump is entered after canned motor pump is pressurized 0.5Mpa, because plunger pump is conveying
Liquid plant, it is unable to air inlet in itself, once air inlet plunger pump with regard to gas lock fever not work done, loses conveying capacity, institute
Conveyed in the liquid state with plunger pump to be ensured, into plunger pump entrance when carbon dioxide should be liquid, in practical operation, generally
It is to be conveyed on the critical-temperature line of gas-liquid, but this process plunger pump is difficult to work in full liquid, because of column
The inlet pressure of plug pump is completed by canned motor pump pressure-raising 0.5Mpa, when gas source pressure inside the tank drops to 2.3Mpa, liquid
Even if carbon dioxide pressurization 0.5Mpa is still in gasification, and plunger pump can not convey gaseous carbon dioxide, due to
The conveying characteristic requirement of liquid carbon dioxide is too narrow, so the efficiency of plunger pump is very low in actual condition, gas source waste is very big,
It is be easy to cause gas lock, causes production efficiency lower.
In order to solve this technical problem, application No. is CN98204169.1's (Authorization Notice No. CN2348096Y)

It is fixed with flange；Referring to fig. 2 and Fig. 6, the recyclable device for recycling gas phase media include recover 60, the bottom of recover 60
Portion is connected with the top of incoming-stream manifold 50, and recover 60 is built-in with the spherical float trap 70 for pressure stabilizing, recover 60 it is upper
Portion is equipped with gas outlet 61, and check-valves 71 is equipped at the gas outlet 61, and gas outlet 61 is connected to external agency storage tank (not through check-valves 71
It shows).Specifically, recover 60 is cylindrical tube, is vertically disposed on incoming-stream manifold 50, float trap 70 can be in cylindrical tube
Internal 360 ° of rotations float up and down, wherein plunger pump is in action process, containing the gas energy after gas medium gasification in 13 chamber of plunger
It enough passes sequentially through admission chamber 210, inlet opening 30, feed liquor runner 100 to be rapidly introduced into incoming-stream manifold 50, then proceedes to rise
And can be hoarded in recover 60 by the peripheral clearance of float trap 70 in recover 60, wherein check-valves 71 opens
It opens energy and gas phase media is recovered in external agency storage tank and reach zero emission requirement.
Referring to fig. 2, the preceding dead-centre position of plunger channel 11 is provided with chock plug component 80, and chock plug component 80 passes through preposition flange
84 are fixed on the pump housing 10, and chock plug component 80 includes that chock plug 81, movable cylinder 82 and the second elastic component 83, movable cylinder 82 are embedded
It being coaxially disposed in chock plug 81 and with plunger 13, the second elastic component 83 top is held between chock plug 81 and movable cylinder 82, specifically,
Movable cylinder 82 is a rigid member, and to matching, the second elastic component 83 can be with for the end size of the size of the rigid member and plunger 13
For rubber spring, since chock plug component 80 has buffer protection effect to plunger 13, so the end of plunger 13 and plunger channel
Preset clearance between 11 corresponding end face can reduce to 2mm, so that the Iinvalid volume in plunger channel 11 is obvious
It reduces, improves the working efficiency of plunger pump.
The working principle of the utility model is as follows: liquid feed valve 201 is opened when plunger 13 moves backward, in incoming-stream manifold 50
The inlet opening 30 containing gas medium successively the feed liquor runner 100 through the pump housing 10, liquid feed valve 201 into the inner cavity of plunger channel 11
Carry out feed liquor, wherein when 201 breakdown of liquid feed valve, gas-liquid can be exchanged moment, and the gas phase containing gas medium, which rises rapidly, leaves plunger
The inner cavity in channel 11 enters in high-order recyclable device, and liquid phase is full of 11 cavity of plunger channel；Plunger 13 is transported forward
Liquid feed valve 201 is closed when dynamic, and plunger 13 holds cavity pressure and increases, and tapping valve is opened, and liquid is discharged out of exhaust chamber, reciprocation cycle
It carries out.Due to hydraulic end of plunger pump 11 center line of plunger channel with combine 12 center line of valve passage for antarafacial setting, so column
The Iinvalid volume filled in the plunger channel 11 of pump greatly reduces, and improves work efficiency, and combine valve passage 12 from top to bottom
It is obliquely installed, correspondingly, the plane where the feed liquor valve port of the liquid feed valve 201 of combination valve 20 is also an inclined surface, such feed liquor
Opening and closing for the spool 22a of valve 201 is carried out on an inclined surface, which ensure that liquid liquid carbon dioxide or other gassiness
Medium is exchanged with prestissimo in dynamic transport and carries out gas-liquid exchange, and wherein gas phase can rise very rapidly up to return positioned at high-order
It receives in device 60 without being trapped in the inner cavity of plunger channel 11, liquid phase then enters in the inner cavity of plunger channel 11, it is ensured that column
Plug pump works under full liquid status (or close to full liquid status), avoids the generation of gas lock phenomenon, further increases the work of plunger pump
Efficiency.On the other hand, the center line of the feed liquor runner 100 on the pump housing 10 and the center line of the inlet opening 30 on valve seat 21 are equal
With combine the angled setting of 12 center line of valve passage, and two angles are identical (i.e. oblique angle β is identical as bevel angle α), and logical with combination valve
(i.e. angle v) is adapted the tilt angle in road 12, and this structure setting shortens circulation path of the gas in uphill process, is subtracted
Flow resistance is lacked, ensure that gas can rapidly increase in recover 60, improve gas-liquid separation efficiency.
