文档介绍：摘要无梁长冲程抽油机是一种大载荷、长冲程、低冲次及自动化程度高、方便节能的抽油机。因此,研究它对于提高采油效率,降低采油成本有相当重要的作用。本次设计采用双电机轮流工作,从而控制抽油杆的上升和下降。所选用的两个电磁调速电机之间用同步齿形带连接。由于电机空载启动, 其启动电流较小, 减小了电机对电网的冲击, 抗电网电流波动能力增强, 功率因数提高。电机输出的功率通过 V 带轮传递给减速器,并且通过减速器对电机输出功率进行调整,然后通过链轮链条传递给抽油杆,最终把电机的旋转运动转化为抽油杆的上升和下降运动。因此,本次设计的主要内容有换向装置方案的选取,电磁调速电机的选取,以及同步齿形带和减速器的设计:其主要包括 V 带设计、齿轮设计和轴的设计。并且通过以上设计达到最终提高采油效率,降低采油成本的目的。所以,本次设计的无梁长冲程抽油机是目前较为理想的机电一体化产品。关键字:无梁长冲程抽油机;电磁调速电机;同步齿形带;减速器;机电一体化 ABSTRACT The b eamless long stroke pumpi ng uni t isa big load, long stroke and low timesnt egrati on of m echat roni c product s.
