Description of drawings
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.Wherein:
Fig. 1 is a complete machine schematic diagram of the present utility model;
Fig. 2 is a hydraulic scheme of the present utility model.
The specific embodiment
Mechanical part of the present utility model as shown in Figure 1 by walking beam 1, preceding horse head 2, support 3, back horse head 4, chassis 5, polished rod eye 6 and front overhang rope 7 and rear overhang rope 7 ' etc. partly form.Rear overhang rope 7 ' be connected wherein with the piston rod of oil cylinder 8.The radius of curvature of back horse head 4 is R, the O ' point of its center of circle on OO ' straight line, and wherein OO ' line parallels with the walking beam axis.Obviously, back arm of force r is a variable, its minimum value r 0At shown position, promptly on the straight line of OO ', this moment R/r 0=2.Select like this be for increase rear overhang rope 7 ' life-span, this moment, the excursion of back arm of force r was r 0~1.24r 0, and the arm of force ratio before and after the walking beam fulcrum is 3.5~4.This kind connected mode is above-mentioned being flexible coupling.
Fig. 2 is a hydraulic system described in the utility model.Wherein main accumulator 9 communicates with the epicoele of oil cylinder 8, finishes the equilibrium function of hydraulic pumping unit in order to replace balancing weight.When the oil sources hydraulic oil enters the middle cavity of resorption 18A of oil cylinder 8, produce a downward active force, the hydraulic oil that meanwhile main accumulator 9 stores enters the oil cylinder epicoele and also produces a downward active force.This two power sum is greater than the peak load of suspension point, thereby horse head raises up and begins oil pumping; The oil sources hydraulic oil enters oil cylinder 19A chamber when horse head is reverse, produces thrust upwards, and the power that this moment, main accumulator acted on the oil cylinder epicoele remains and is directed downwards, and the difference of this two power also is the power of directed downwards, in order to balance minimum polished rod load power.The arithmetic mean of instantaneous value of load pressure curve on upper and lower both direction that the result of balance can make oil sources produce equates, is referred to as the complete equipilibrium of hydraulic pumping unit.
Among Fig. 2 by two-position four-way electro-hydraulic reversing valve 14, formed exchange system near the disk G on switch a, b and the cylinder rod.As the disk G on the cylinder rod during, just send commutation signal, so reversal valve 14 commutations make hydraulic oil enter cavity of resorption 18A in the oil cylinder, the middle epicoele 19A oil return of oil cylinder near switch a.Thereby cylinder rod moves downward; As disk G during near switch b, the circuit of reversal valve 14 is reverse, and hydraulic oil is admitted to the middle epicoele 19A of oil cylinder, middle cavity of resorption 18A oil return again.The oil pumping action of oil pumper has been finished in motion so repeatedly.In addition in order to continuously change the stroke of oil pumper, should be able to continuously change near the position of switch b.
Oil sources shown in Fig. 2 by motor 24, manually Variable plunger pump 25, thick oil consider 26, parts such as one way valve 23, essential oil filter 22, electromagnetism drain charge overflow valve 27, remote pressure regulating valve 28 and fuel tank 31 form, wherein by motor 24, manually the part formed of Variable plunger pump 25, thick oil filter 26 and one way valve 23 can be that a cover also can be two to overlap parallel connection.The hydraulic oil that oil sources is got is mainly supplied with the reversal valve 14 of exchange system.The swash plate angle that wherein changes manual Variable plunger pump 25 can continuously change flow, thereby continuously changes the jig frequency of oil pumper.
Accessory system shown in Fig. 2 comprises oil-supplementing system, weakening system, brake system, super disconnected six parts such as stopping alarm system, liquid level stopping alarm system and temperature stopping alarm system of carrying.Wherein oil-supplementing system is made up of little accumulator 10, one way valve 11, flow speed control valve 12, two two energising magnetic reversal valves 13 and the formula overflow valve 20 that leaks.One of function of oil-supplementing system is to save the energy, the efficient of raising system, because the opening pressure of overflow valve 20 is transferred to little maximum load pressure during greater than system works here, and the opening pressure of overflow valve 27 and remote pressure regulating valve 28 is transferred to much larger than the opening pressure of overflow valve 20, the commutation moment of current horse head 2, the instantaneous velocity of cylinder rod reduces greatly and even moment is zero, thereby oil supply pressure suppressed height, forces it to enter accumulator 10 through overflow valve 20 and stores.The pressure of load pressure in the accumulator 10 so the liquid in the accumulator 10 just flows into oil cylinders through one way valve 11, flow speed control valve 12 and reversal valve 13, thereby increases the movement velocity of oil cylinder when entering normal operating conditions after horse head commutation finishes.Here quoting flow speed control valve 12 is to make the speed of oil cylinder all permanent; Two of the effect of oil-supplementing system is that horse head produces upward fast slow movement effects down before making, even reversal valve 13 and reversal valve 14 interlocks make its only conducting when horse head is up, emits the hydraulic oil in the accumulator 10, and reversal valve 13 cut out when horse head was descending.
Weakening system among Fig. 2 is formed in parallel, and it is gone here and there in main oil return line by choke valve 29, two two energising magnetic reversal valves 30.Its principle is for heavy oil wells and the poly-well of annotating, when horse head is reverse by top dead-centre, maximum polished rod load on the horse head does not disappear immediately, thereby the active force that produces at the epicoele of oil cylinder 8 of accumulator 9 is not enough to withstand the peak load power on the horse head, so horse head is descending, cylinder rod is up.When the maximum polished rod load pop-off of horse head and when changing over minimum load, the active force that accumulator 9 produces at oil cylinder 8 epicoeles is again greater than the reduced value of minimum polished rod load on cylinder rod, thereby horse head 2 is up slightly again, and this is vibration.General this vibration has only 1~2 time, if quote above-mentioned weakening system, when horse head 2 reversal valve 30 and reversal valve 14 interlocks oppositely the time, moment is closed its flow channels, oil return is all passed through by choke valve 29, thereby in oil cylinder 18A chamber, producing a very big back pressure, the active force that the hydraulic oil in the accumulator 9 produces at oil cylinder 8 epicoeles can't overcome the back pressure that oil return produces, and has therefore stoped vibration to take place.Because vibration only continues about 1 second, reversal valve 30 also only cuts out a second under the time-delay relay effect, therefore oily temperature and efficient is not had influence.
Brake system shown in Fig. 2 is made up of 18,19 and two two energisings of hydraulic control one-way valve magnetic reversal valve 15.Oil sources has enough pressure to open two hydraulic control one-way valves 18 and 19 during oil pumper work; Reversal valve 15 is received the control mouth of hydraulic control one-way valve in the oil return line when needs brake, and makes the position that horse head is parked in immediately to be needed.
Overload shown in Fig. 2, a disconnected year stopping alarm system are by having high and low pressure electrical contact switch K GAnd K DPressure meter 21 form, the pressure-activated value of two contacts can arbitrarily be provided with.When sucker rod broke, load pressure was inevitable very low, thereby low tension contact switch K DClosure makes system's stopping alarm that cuts off the power supply immediately; When being stuck with the sucker rod that should the down-hole breaks down, maximum polished rod load must surpass setting value, thereby high-tension electricity contact switch K GConnect, force system-down to be reported to the police.
Liquid level stopping alarm system among Fig. 2 is made of liquid level sensor 16; and temperature stopping alarm system is made of temperature pick up 17; when liquid level is lower than dangerous values or temperature and is higher than dangerous values; starting of liquid level stopping alarm system or the starting of temperature stopping alarm system are reported to the police shutdown of pumping machine.
Walking beam is hard the connection with the connected mode of cylinder rod among Fig. 2, adopts needle bearing to connect therebetween, and the arm of force is 3.5~4 than still before and after the walking beam fulcrum.Firmly, soft two kinds of life-spans that connected mode can both improve oil cylinder, all have the characteristics of linear and the no additional-energy loss of transmission, wherein syndeton is simple firmly, but that cylinder force is flexible coupling is slightly larger; The flexible connection structure complexity, but cylinder force is more less.
