曲卷式抽油机的研究

曲卷式抽油机是由曲柄连杆机构通过齿条和齿轮带动卷筒、钢丝绳和悬绳器作上下往复运动的抽油机.其实质是游梁抽油机的一种变形,因此,它有游梁抽油机的耐用度和可靠性.其运动机理与游梁抽油机基本相同,但其所产生的加速度和动载荷较小.它通过长冲程低冲次的运行方式,最大限度地减少了冲程损失,提高了采油系统效率,延长了机、杆、泵的使用寿命,是一种理想的高效节能采油机械.

The research of crank-guide blue elephant driven by hydraulic pressure gears

the new type of pumping unit is a kind of pumping uint which its crank-guide unit pumps through drums,drilling line and beam hanger driven by racks and gears. It is essentially a kind of transfiguration of the pump unit with walking beam, therefor it still has the durability and reliability of the pumping unit with walking beam,it has same opecetion mechanism compared with the pumping unit with walking beam, but it reduces the stroke loss,enhances efficiency of the oil recovery system and prolongs the service life of engine, perch and pump in the way of long strokes and low frequency of stroke, so it is a favorable oil recovery machine with high efficiency and energy saving.
