本发明的液压泵站为现有技术。 Pump station is prior art to the present invention.

本发明的工作原理:首先启动液压系统油泵,调整系统压力、冲次、冲程及油温控制等。 The working principle of the invention: first start hydraulic system pump, adjust the system pressure, stroke rate, stroke and oil temperature control. 柱塞7在泵筒5中构成上、下两个独立的工作腔,以空心抽油杆4上的两个液压缸为动力,同步带动抽油机柱塞7上、下运动,在上下冲程中上、下腔分别完成进、排油,从而达到全行程连续抽油。 The plunger in the pump cylinder 7 5 constituting the upper and lower two independent working chambers, a hollow rod 4 of the two hydraulic cylinders driven, entrainment pumping plunger 7 move up and down, up and down strokes upper, lower chamber inlet were completed, drain, so as to achieve a continuous full-stroke pumping.

抽油机在上冲程时,柱塞7上升,此时底阀15打开,油进入下液压缸11下面的油管14的内腔,空心抽油杆4上的下腔游动单向阀8和单向阀13关阀,并随空心抽油杆4上升,此时泵筒5下腔产生负压,安置在泵筒5上的下腔固定单向阀10打开,套管17与泵筒5间的油进入下腔,泵筒5上腔内的油由于柱塞7压缩压力升高,上腔的上腔游动单向阀6打开,油进入空心抽油杆4内腔,上腔的上腔固定单向阀3关闭。 When the pumping stroke, the plunger 7 rises, valve 15 is opened the end of this time, the oil enters the interior of the hydraulic cylinder 11 below the tubing 14, the hollow rod floating way on the lower chamber 4 and valve 8 check valve 13 off the valve, and with the hollow rod 4 is raised, this time the pump chamber under a negative pressure tube 5, disposed in the lower chamber is fixed on one-way valve 10 the pump cylinder 5 is opened, the pump cylinder 17 and the sleeve 5 oil between the lower chamber into the upper chamber 5 of the pump cylinder oil pressure rises due to the compression of the plunger 7, the upper chamber of the floating upper chamber unidirectional valve 6 is opened, the oil entering the lumen of hollow rod 4, the upper chamber fixing the check valve upper chamber 3 is closed. 油穿过上液压缸2从空心抽油杆4进入出油管1完成了上冲程的抽油过程。 2 through the upper oil hydraulic cylinder 4 into the hollow sucker rod from the pipe 1 finished the stroke pumping process. 液压缸(2、11)的换向是靠液压泵站12的光控制来实现的。 A hydraulic cylinder (2, 11) is commutated by the light control 12 of the pump station to achieve.

抽油机在下冲程时底阀15关闭,下液压缸11下面的空心抽油杆4下行,油管14内腔的压力升高,装在空心抽油杆4上的单向阀13打开油进入空心抽油杆4向上流动,这时由于柱塞7的下行泵筒5的下腔油受压缩压力升高,下腔游动单向阀8打开,下腔的下腔固定单向阀10关闭油进入空心抽油杆4内腔,穿过柱塞7、上液压缸2从空心抽油杆4进入出油管1完成了下冲程时的抽油过程。 Next pumping stroke of the bottom valve 15 is closed, the hydraulic cylinder 11 below the hollow rod 4 downward, the pressure lumen tubing 14 is increased, the check valve installed in the hollow rod 4 of the oil 13 opens into the hollow rod 4 upward flow, since the down time of the pump cylinder of the plunger 7 of the lower chamber 5 is compressed oil pressure rises, the check valve 8 is opened traveling chamber, the lower chamber of the lower chamber 10 to close the check valve is fixed oils 4 into the lumen of the hollow rod, through the plunger 7, the hydraulic cylinder 2 from the hollow rod 4 into the pumping process when the pipe 1 is completed next stroke. 从而达到了抽油机上、下冲程时连续抽油的目的。 So as to achieve the pumping unit, the purpose of continuously pumping oil lower stroke.

液压泵站中电机带动油泵,经过滤器从油箱中把油抽出,通过溢流阀可调整系统压力。 Motor driven hydraulic pump station, through the filter out the oil from the tank, through the relief valve to adjust the system pressure. 在液压管路中装有真空相变散热装置,当加热工作介质时可迅速升高导热温度,因此在液压抽油工作的同时,也提高了油井内的温度,从而突破性地解决了在稠油井采油时需要加热的问题。 In the hydraulic circuit equipped with a phase change heat vacuum apparatus, when the heating medium can rapidly increase the working temperature of the thermal conductivity, so while the hydraulic pumping work, but also raises the temperature in the well, so that a breakthrough in solving the fused requiring heating oil when oil problem. 图中所示的单向阀22的开启压力大于单向阀19的压力,当回油时单向阀19首先导通对真空相变相散热装置供油,然后单向阀22导通油回油箱。 Cracking pressure check valve 22 shown in FIG pressure is greater than the check valve 19, when the oil return check valve 19 is turned on first vacuum supply transformation phase heat sink pair and the one-way valve 22 is turned to the reservoir and . 当液压换向时,单向阀(20、21)的工作原理与单向阀(19、22)的工作原理相同。 When the hydraulic reversing, the same one-way valve (20, 21) works with a one-way valve (19, 22) works. 从而保证真空相变散热装置内导热油的损耗。 Thus ensuring vacuum within the phase change heat sink HTF loss.
