  • 在使用蒸汽轮机之前对其加热的时候,主要的蒸汽断流阀(在锅炉后)有一个旁路管线,可以允许其过热。在使系统中的管线及蒸汽轮机过热之前,蒸汽缓慢通过阀门旁路。此外,一个齿轮传动装置在没有蒸汽被提供给蒸汽轮机的时候,以缓慢转动轮机来保持一个防止不平衡膨胀及转子弯曲所需的连续供热。在通过齿轮转动使轮机做第一次转动以及转子呈平直(不弯曲)状态所允许的时间之后,齿轮脱离,蒸汽注入轮机。对于大多数公用事业和工业蒸汽涡轮机,一个起动和载荷表格会包含在单元使用说明书里。其作用是指导轮机操作人员在加载汽轮机的时候,不仅要使转子转速及外壳所受热应力最小化,还要使转子升温快于外壳的机会最小化。当起动一台船用蒸汽轮机(海上单位),蒸汽通常会先被注入位于lp(低压)轮机的后部桨叶,然后进入前部桨叶缓慢的使轮机以10-15圈每分钟(rpm)的速度旋转使轮机缓慢加热。完全手工翻译,你参考一下吧

  • Abstract: This paper studied the effects of different water-based wax consistency on the anticorrosiveness of blueish steel strips. Their performances on anticorrosion were observed via simulated industrial experiments from which the desirable working wax concentration range was found, aiming at the improvement on anticorrsion ability. The optimum wax working concentration and its most applicable storage condition have been figured out by comparative study on different concentrations and between coated and uncoated scenarios under differenct reaction time. This is to help in finding the best possible setting of wax concentration for steel strip coating applicable to industrial production and to provide references for commercialization.关键词:涂蜡发蓝钢带,防锈剂,电化学腐蚀,模拟工业气候实验。Key Words: wax coated blueish steel strip, antirust agent, electrochemical corrosion, stimulated industrial experiment
