抽油机是人工举升开采石油的主要设备。在近几年来,尤其是游梁式抽油机再应用的过程中,出现许多的因为曲柄销损坏而引起的事故,严重的影响了油田的正常生产。而究其原因,主要是因为其中的轴承座出现的各种问题。本文就抽油机发生的事故着手,分析具体的原因,介绍轴承座的相关内容,并重点阐述抽油机轴承座的加工改进设计,从而保证抽油机工作的安全性。 The pumping unit is the main equipment for artificial lift and oil extraction. In recent years, especially when the beam pumping unit is re-applied, many accidents caused by the crankpin damage have occurred, which seriously affects the normal production of the oilfield. The reason, mainly because of the various bearing problems. In this paper, the accident occurred pumping unit to start, analyze the specific reasons, introduce the bearing seat of the relevant content, and focus on the pumping unit bearing the improvement of the design, so as to ensure the safety of pumping work.
