摘要
在立井提升过程中,缓冲导向主要靠箕斗上的滚轮罐耳与罐道配合,由于受冲击及井筒淋水因素影响,滚轮罐耳内受力碟簧易失效、寿命短、维护频繁、成本高。提出一种简易的滚轮罐耳改进方法,现场应用良好。
In the process of ascension shaft, buffer tank guided mainly by the skip roller ears with the tank track fiting,duo to the impact and the wellbore trick factors,disc spring prone to failure of skip roller ears, short life, maintenance frequent and high cost. skip roller ears is improved in this paper, field good application.
