液化气体铁路罐车所运输的介质大多为易燃、易爆、有毒的介质。为使其安全运行,杜绝事故的发生,其中介质的泄漏是首要考虑的问题。引起介质泄漏的途径有多种,但滑管式液位计泄漏较为常见。据铁道部统计,1994年液化气体铁路罐车在运输途中发生四起泄漏事故,有三起为滑管液位计的泄漏。占75%。又据齐鲁石化公司某厂所使用的160辆罐车运行20余年历史资料表明,滑管液位计泄漏的核心问题是滑管内的密封泄漏。因而,如何解决液化气体铁路罐车(体)滑管
Most liquefied gas tanker transport medium is flammable, explosive, toxic medium. In order to make it run safely and eliminate the accident, medium leakage is the primary consideration. A variety of ways to cause media leakage, but the slide tube level gauge leakage is more common. According to the statistics of the Ministry of Railways, four leaks occurred in the transport of liquefied gas railway tankers in 1994, and three of them were leaks of slide tube level gauges. 75%. According to a factory in Qilu Petrochemical Company used 160 tanker running more than 20 years of historical data show that the slippery pipe level gauge leak is the core problem of leakage within the slide pipe seal. Therefore, how to solve the liquefied gas railway tank (body) slide pipe
