Embodiment
Referring to Figures 1 and 2, together with Fig. 1 is vertically connected with Fig. 2.
High-efficiency anti-corrosion wearing inclined shaft pump, including pump barrel assembly, travelling valve assembly for plunger and standing valve assembly, wherein, pump Cylinder assembly includes pump barrel 1 and the pump barrel box cupling 2 being connected with the end of pump barrel 1.
Travelling valve assembly for plunger includes being arranged on plunger upper part valve bonnet 3 and plunger 4 in pump barrel 1, up and down the two of plunger 4 End is connected to moving valve unit, wherein, moving valve unit includes being movably equipped with travelling valve in travelling valve bonnet 5, travelling valve bonnet 5 Ball depression bar 6, is arranged with travelling spring 7 on travelling valve ball depression bar 6, and one end of travelling spring 7 is mutually fixed with travelling valve bonnet 5, The lower end of travelling valve ball depression bar 6 is fixed with travelling valve ball 8, and the lower end of travelling valve bonnet 5 is connected with travelling valve seat 9, the upper end of plunger 4 Moving valve unit be connected with plunger upper part valve bonnet 3, also sealing is provided with plunger connector 10 in pump barrel, and plunger connector 10 is arranged on post Between plug 4 and the moving valve unit of upper end.Plunger upper part valve bonnet 3, travelling valve bonnet 5, plunger connector 10 and plunger 4 respectively with pump barrel 1 sealing is slidably connected.
During work, when fluid enters fashionable, fluid opens travelling valve ball 8, and travelling valve ball 8 is along travelling valve ball depression bar 6 to moving up It is dynamic, and travelling spring 7 is compressed, travelling valve bonnet 5 can play a part of righting with travelling spring 7, and centering is good, works as travelling valve ball 8 need close when, force valve ball to be closed by the effect of spring force, so prevent travelling valve ball 8 from closing delayed, improve pump Effect.The effect that the upper and lower moving valve unit of plunger relies on spring force forces valve ball to be closed, and is pumped in level, inclined shaft When, the effect that valve ball can also should be spring force makes its normal work.
Wherein, standing valve assembly includes the standing valve cover 11 being connected with the lower end of pump barrel 1, and the lower end of standing valve cover 11 is successively It is connected with fixed valve base 12 and fixed valve base joint 13, fixed valve base 12 and fixed valve ball 14 is installed, is set on fixed valve ball 14 There is the fixation spring 16 for being arranged with and mutually being fixed with standing valve cover 11 one end on fixed valve ball depression bar 15, fixed valve ball depression bar 15, Gu Valve bonnet 11 is determined provided with multiple spiral helicine grooves 17.When fluid top opens the elastic force of fixed spring 16 and open fixed valve ball 14 Enter fixed cover 11, in the presence of spiral helicine groove 17, liquid stream rotates into pump barrel 1, so passes through the energy of standing valve depression bar 15 Good guide effect is played, well liquid enters the pump chamber pressure drop larger without causing, during 4 up stroke of plunger, what pump can be full of It is faster more complete, thus the release of solution gas is reduced, fixed valve ball 14 can be made by fixed spring 16 and standing valve depression bar 15 Quick closedown on fixed valve base 12 is fallen into, pump efficiency is improved.
Plunger connector 10 is linked together by surely following closely with travelling valve bonnet 5 and plunger 4 respectively, can improve steadiness, extension Service life.
Operation principle:After going into the well during imbibition, under head of liquid effect, well liquid top opens fixed valve ball 14 and enters standing valve cover 11, under the effect of spiral helicine groove 17, liquid stream rotates into pump barrel 1, while forcing fixed valve ball 14 to rise completes imbibition Journey;In pump discharge opeing, the rapid decrease under the effect of intraluminal fluid column pressure and under the elastic force effect of fixed spring 16 of fixed valve ball 14, Seat closes rapidly valve, realizes the discharge opeing process of pump on fixed valve base 12.Such a structure increases suspended solid in well liquid The suspension time of grain, thus reduce the lower liquid speed degree and deposition of solid above valve.In addition, by spiral helicine groove 17, When oil well pump liquid sucking-discharging, the filling well liquid mode of pump can be changed, the ability that pump controls compressible fluid is improved.Work as fixed valve ball 14 when leaving fixed valve base 12, and inlet flow rate area increases sharply, and taper liquid stream is formed, using consolidating with helical groove 17 Determine valve bonnet 11, well liquid enters the pump chamber pressure drop larger without causing, during 4 up stroke of plunger, it is faster more complete that pump can be full of, The release of solution gas thus is reduced, during down stroke, plunger 4 touches a large amount of well liquids quickly, and which improves compression ratio, post Plug 4 compresses extricator and opens travelling valve ball 8, prevents gas lock.
The utility model is not limited to above-mentioned embodiment, in the knowledge that those skilled in the art possess, It can also be made a variety of changes on the premise of the utility model objective is not departed from, the content after change still falls within the utility model Protection domain.
