论文部分内容阅读
《石油钻采机械》1984年第3期刊登了四川省石油管理局川东钻探公司机动科郑辉同志题为《F320型钻机气控元件与国产气控元件的互换问题》的文章。近几年来,四川局的同志们在选择国产气控元件代用F320型钻机气控元件方面做了大量工作。然而,我们认为在该文的气控元件对照表中还存在一些问题需更正,以便能准确地选择气控元件,其次也兼作对郑辉同志文章的一个补充吧。
“Petroleum Drilling and Mucking Machinery” No. 3, 1984 published in Sichuan Province Petroleum Administration Chuandong Drilling Company Mobile Division Zheng Hui, entitled “F320 type rig pneumatic control components and domestic gas-controlled components of the exchange problem” article. In recent years, comrades in Sichuan Bureau have done a lot of work in choosing the domestic gas-control components to replace the pneumatic control components of the F320-type rig. However, we think there are some problems to be corrected in the control charts of the article, so that we can accurately select the air-control components. Secondly, it also complements Zheng Hui’s article.
