摘要
针对胜利油田气平衡式链条抽油机存在的故障率高和现场维修困难等问题 ,指出了该机存在的主要问题是气平衡系统不可靠 ,换向系统结构不合理 ,运动副润滑不良以及没有故障保护功能等。提出了技术改造的原则和结构方案 ,并通过对比优选出了技术改进的实施方案 ,经现场应用表明 ,改造后的链条抽油机运转平稳 ,可靠耐用 ,经济效益显著。
Field application of the air-counterbalanced chain-drive pumping unit in Shengli Oilfield witnesses such problems as high failure rate and difficult field maintenance.The paper analyses the main reasons cause these faults that are unreliable air counterbalance system,unreasonable reversing system structure design,bad lubrication and lack of emergency protection function.On this basis,principle and alternatives for the chain-drive pumping unit improvement are put forware,and by means of comparison and optimization,the executive plan of technological transformation is choised.Through field application,the results show that the improved chain-drive pumping unit is of smooth performance,high reliability and durability,and obvious economic benefit.
