为了解决我国含硫气田仪表用的轴承,以满足开发天然气资源,实现自动化控制生产的需要,一机部“1975—1976年机械工业科学技术发展规划”中要求我所开展“在含硫化氢介质中工作的轴承”的研究与试制,经过三年多的工作,在兄弟单位的大力支持与密切配合下,研制成功了两种抗硫轴承,经装机现场考核,达到了预期的目的,满足了用户的要求,现将抗硫轴承的研制情况介绍如下。 一、抗硫轴承试制型号的确定 多数天然气矿都含有硫化氢,它是一种即毒且腐蚀性极强的气体。硫化氢与铁反应生成硫化铁,呈片状剥落,一般材料少则几天,多则几十天即可蚀穿。就是经过脱硫处理的天然气,虽然大量的硫化氢气已被脱除,但残存的极少量的硫化氢仍具有可观的
In order to solve the need of bearings used in the instrument of sulfur-containing gas field in our country to meet the need of developing natural gas resources and realize the automatic control of production, a mechanical department “1975-1976 Machinery Industry Science and Technology Development Plan” asked me to carry out “ In the work of bearing ”research and trial production, after more than three years of work, brothers units in the strong support and in close cooperation with the successful development of the two anti-sulfur bearings, installed by the on-site assessment, to achieve the desired purpose, to meet The user’s request, now the development of anti-sulfur bearing introduced below. First, determine the type of anti-sulfur bearing trial Most natural gas mines contain hydrogen sulfide, which is a poison and highly corrosive gas. Hydrogen sulfide and iron react to form iron sulfide, exfoliated flakes, generally less than a few days, as many as dozens of days to eclipse through. Is desulfurized natural gas, although a large amount of hydrogen sulfide has been removed, but the remaining small amount of hydrogen sulfide still has considerable
