摘要： A hydraulic oil well pumping arrangement is disclosed. The system employs a compensating type hydraulic pump, a directional valving arra A hydraulic oil well pumping arrangement employs a compensating type hydraulic pump, a directional valving arrangement and a proportioning valving arrangement. When the directional valve is energized, oil is directed to the rod end of the hydraulic cylinder. The rod or piston part of the hydraulic cylinder will then elevate until a first limit switch is actuated which then will de-energize the directional valve and send a current signal to the proportional valve. This current signal to the proportional valve forces it to open to a point at which the cylinder rod would extend at the desired velocity until it reaches a second limit switch. The second limit switch is near the bottom (for example, 1 foot, or 0.30 meters) of travel of the rod or piston. The current signal to the proportional valve is then decreased, creating a choking arrangement that forces the cylinder rod to decelerate. The cylinder rod then reaches another limit switch. Upon reaching the third limit switch, the signal is removed from the proportional valve so that it closes. This halts a draining of fluid from the hydraulic cylinder. At the same time, a voltage signal is sent to the directional valve opening it so that pump flow again travels from the pump to the hydraulic cylinder and once again elevates the rod and the connected pumping string or sucker rod.
摘要翻译：公开了一种液压油井泵送装置。该系统采用补偿型液压泵，方向阀arra A液压油井泵送装置采用补偿式液压泵，方向阀装置和配比阀装置。当方向阀通电时，油被引导到液压缸的杆端。然后液压缸的杆或活塞部分将升高，直到第一限位开关被致动，然后将使换向阀断电并向比例阀发送电流信号。到比例阀的这个电流信号迫使其打开到一个点，在该点处气缸杆将以所需的速度延伸，直到达到第二限位开关。第二限位开关靠近杆或活塞的底部（例如，1英尺或0.30米）。然后减小到比例阀的电流信号，产生迫使气缸杆减速的阻塞装置。然后，气缸杆到达另一个限位开关。到达第三限位开关后，信号从比例阀中取出，使其关闭。这就停止了从液压缸排出的液体。同时，将电压信号发送到打开它的方向阀，使得泵的流量再次从泵传送到液压缸，并且再次升高杆和连接的泵送柱或抽油杆。
