据了解,目前各输油泵站的浮顶油罐尚未安装极限液位自动报警装置。正常生产时,当班工人必须随时监视罐内油面的高度。从一些泵站出现的“冒顶”苗头和已经发生的“冒顶”事故看,单纯靠人工用眼监视液位的办法是不太可靠的,需要设计安装一种安全可靠、使用方便的液位显示和报警装置,才能有效地防止事故发生。 下面以15m高浮顶油罐为例,简要介绍一种液位显示和自动报警装置的工作原理。 浮顶油罐最高油面不得超过14.5m(实际控制在14m);最低油面不得低于2 m(实际
It is understood that at present the oil pump station floating roof tank has not yet installed limit level automatic alarm device. Normal production, on-duty workers must always monitor the level of oil tank. From the “fall roof” signs and the “roof fall” accidents that have occurred in some pumping stations, the method of monitoring the liquid level by artificial eyes is not reliable and requires the design and installation of a safe, reliable and easy-to-use liquid level indicator And alarm device, can effectively prevent the accident. The following 15m high floating roof tank, for example, briefly introduces a liquid level display and automatic alarm device works. The maximum oil level of a floating roof tank shall not exceed 14.5 m (actually controlled at 14 m); the minimum oil level shall not be less than 2 m
