Abstract
The utility model discloses an automatic stirring sand oil-well pump which is used mainly for deep wells in oil fields. A drive mechanism is arranged on the ground; the utility model is provided with a piston for lifting fluid to the ground and an upper free valve, and the piston and the upper valve which are connected are sheathed with a pump cylinder outside, the lower end of the pump cylinder is communicated with a standing valve; the valve seat and the valve core of the upper free valve are a conical valve seat and a conical valve core which are corresponding, and the end part of the valve core is provided with an impeller. The upper discharge end of the upper free valve can be a spiral mouth, and the upper discharge end of the standing valve can also be a spiral notch or an oblique mouth. Accordingly, oil flow which enters into the pump cylinder can form stirring spiral flow to ascend, so that the deposition of sand in oil can be effectively prevented, and the utilization efficiency and the service life of the pump can be improved.
Description
Automatically stir husky oil well pump and be mainly used in oil field deep well.Driving mechanism is positioned at ground, have lifting fluid earthward piston, form by the pump barrel of the traveling valve of piston, piston end you and overcoat.
Existing tubing pump all by pump barrel, be positioned at pump barrel plunger (piston) and on move about all (valve) you, down move about all (valve) you, be communicated in the pump barrel lower end fixing all (valve) that assembly form.Plunger and the last travelling valve that fuses, following travelling valve pump in pump barrel, enter from standing valve assembly lower contact suction inlet twitching extraneous oil, oil outlet by standing valve assembly upper end imports pump barrel, travelling valve imports guide in link and the plunger under passing through again, derives from upstream valve sidewall oilhole.These oilholes all are straight oral pore or straight wall slotted eye.Because there is a large amount of sands in regular meeting in the oil, sand will deposit in the interior oil of timely pump barrel.Particularly contained native sand will deposit between upstream valve and the pump barrel in the oil after discharging the upstream valve, cause the quick wearing and tearing of these two parts and plunger.Sand precipitates from the oil of oil outlet importing pump barrel lower end, standing valve assembly upper end equally, also easily enters between downstream valve and the pump barrel to reach between plunger and the pump barrel, quickens the wearing and tearing of these parts.And when down valve pin opening be straight mouthful, a mouthful end face was the plane of broad, stopped husky mobile of oil, and the easier sand that makes is irritated the into slit between the opening end and pump barrel.
The purpose of this utility model is to provide a kind of oil to flow in pump barrel, is difficult for the deposition sand, reduces sand the pump barrel wearing and tearing are stirred husky oil well pump automatically.
Oil well pump of the present utility model has pump barrel, is positioned at the piston of pump barrel, upper travelling valve you, the standing valve that is communicated with the pump barrel lower end.You are connected piston and upper travelling valve, and one coexists pumps in the pump barrel.Its structural feature is: no longer adopt the lower travelling valve that; Upper travelling valve your valve seat and spool are corresponding cone, and valve seat can be conical surface, and conical spool passes from valve seat, and the male cone (strobilus masculinus) of spool contacts with the inner conical surface of valve seat, form face seal; The spool end has impeller.Oil in entering pump barrel is flowed through upper travelling valve at that time, by the impeller guiding, makes oil stream form eddy flow and rises.Can stir sand in the pump barrel like this, particularly upper travelling valve that position reaches the sand with the upper part, and it is risen with eddy flow, can not produce deposition.Also reduced simultaneously the sand that falls between upper travelling valve that and the pump barrel, reduced wear.Spool also can also prevent that impurity such as sand are clipped in the sealing surface between valve seat and the spool, more help one-way sealing along with floating rotation.In order further to increase eddy flow, your last exhaust end of upper travelling valve is the spiral mouth, and the whelk of discharging from the spiral mouth screws on liter, more effectively prevents to deposit sand, significantly reduces sand and falls between pump barrel and the upper travelling valve that.The spiral mouth can be the spiral diagonal cut joint, also can be the spiral notch of opening at sidewall, can also be the guiding groove of screw shaped.In order to make the oil of discharging from pump barrel flow the sand that do not sink, the pull bar that can also connect in your upper end of upper travelling valve also be provided with spiral fluted and stir husky device.The oil stream of discharging is directed to up eddy flow again through stirring husky device.
Long-pending husky for you enter pump barrel from standing valve oil is not produced, you are preferably spiral notch or angle by upper outlet standing valve, make the oil through spiral notch or angle form eddy flow, stir sand and do not sink, and eddy flow rises and enters in pump barrel and the piston.For oily stream can be entered in the piston from pump barrel glibly, the under shed of piston is a horn mouth, reduces resistance, and sand enters the opportunity between pump barrel and the piston in the minimizing oil stream.Equally, for oil also forms eddy flow in piston, can in piston, be added with helical guide groove, or be added with guide vane wheel.Can cooperate the impeller of standing valve that upper outlet, spool end and the spiral mouth that the upper travelling valve that is gone up exhaust end like this, stir oil in pump barrel, the eddy flow of formation stirring rises, and prevents that effectively sand sinks in the oil.
So compared with the prior art the utility model, has can form eddy flow in pump barrel, stir sand, and it is not deposited, and guarantees using normally and efficiently of pump, has reduced the wearing and tearing of pump simultaneously, improves the working life of pump.
Accompanying drawing has been represented a kind of structural representation that stirs husky oil well pump automatically of the utility model.
This stir automatically husky oil well pump by pump barrel 7 pistons 10, upper travelling valve you 17, standing valve you 2 form.You fuse piston and upper travelling valve by connecting head 13, and in the pump barrel of together packing into.The piston under shed is flaring opening 8.The piston inner flow passage is added with helical guide groove 9.Your interior valve seat of upper travelling valve is the valve seat 15 of annular conical surface, and cone spool 14 passes valve seat.The bottom guide bar of spool passes the guide hole in the joint, with following impeller 12 sockets, and is fixed in guide rod with nut 11.Impeller 16 also is equipped with in spool 14 upper ends.It is the spiral mouth that the upper travelling valve that is gone up exhaust end, and is provided with the guiding spiral chute along axle.Your upper end of upper travelling valve has pull bar 19, and rod outer sleeve has spiral fluted to stir husky device 20.Upper end at pump barrel also has joint 18.The pump barrel lower end is connected by joint 5 and standing valve that 2.Your upper outlet 6 of standing valve is the spiral notch, is communicated with pump barrel.Chimney filter joint 1 is established in your lower end of standing valve, and standing valve that seat 3 and valve that ball 4 are arranged in it.When you up and down reciprocatingly work in pump barrel with pull bar when piston and upper travelling valve, oil from chimney filter enter standing valve you and discharge from upper outlet 6 spirals, the eddy flow of formation successfully flows through piston under shed 8.Enter oil in the piston helical guide groove of flowing through, quicken eddy flow, after impeller 12 stirs, pass your valve seat of upper travelling valve, stir from upper travelling valve spiral mouth and the guiding spiral chute 22 that you go up exhaust end through impeller 16 again and discharge, and form eddy flow and rise.The oil that eddy flow rises and discharges from pump barrel also can stir husky device through the spiral chute of rod outer sleeve and stir the rising of continuation spiral, has prevented sand deposition in the oil effectively, has reduced the wearing and tearing of sand to pump barrel and piston space.
