滚筒式抽油机的调查与分析
Improvement on drum type pumping unit
【摘要】 论述了发展滚筒式长冲程抽油机的有利条件。针对现有滚筒式抽油机存在钢丝绳寿命短和换向装置可靠性差等问题,提出了采用辅助绳柔性传动降低柔性件上的载荷,从而提高柔性件使用寿命,以及采用无切换的连杆-齿轮机构的机械换向装置提高换向可靠性的方法。据此,设计了一种滚筒式抽油机,其动力性能优于现有的游梁式抽油机。
【Abstract】 The favourable conditions for developing the drum type long stroke pumping unit are expounded. In the light of the problems with the existing drum type pumping units, including short service life of the wire rope and disappointing reliability of the reversing mechanism, solutions are presented, i. e. adopting the auxiliary flexible drive to reduce the load on the flexible elements to improve their service life and adopting the pitman-gear mechanism to improve the reliability of the reversing mechanism. On these grounds, a new drum type pumping unit that has better dynamic performance than beam pumping units is designed.
