经常化验锅炉水,可以及时分析锅炉内的水质情况。它是监督机车锅炉水处理的必要手段,是防止腐蚀、减缓水锈生长速度的重要措施。化验时,检验锅炉水碱度的目的是监督是否会发生腐蚀或苛性脆化;检验含氯量的目的是衡量锅炉水的浓缩倍数和是否会析出结垢物,粘附在锅炉板上形成水锈。我段地处厦鹰线中段,使用江河地表水,水中含氯量比较少(仅1～2毫克/升),但水受消毒余氯的影响,含氯量有显著的变化。为了指导软水作业,在多年实践的基础上,经过研究和试验,制成SZ-81锅炉水
Regular laboratory boiler water, boiler water quality can be analyzed in time. It is an indispensable means of supervising the locomotive boiler water treatment and is an important measure to prevent corrosion and slow down the growth of water rust. During the test, the purpose of testing the boiler’s water alkalinity is to monitor whether corrosion or caustic embrittlement will occur. The purpose of testing the chlorine content is to measure the concentration factor of the boiler water and whether scale deposits will precipitate and adhere to the boiler plate to form water rust. The section I was located in the middle of Ha Long Line, the use of surface water of rivers, the water is relatively small amount of chlorine (only 1 ~ 2 mg / l), but the water affected by residual chlorine, chlorine content significantly changed. In order to guide the soft water operations, based on years of practice, through research and experimentation, made of SZ-81 boiler water
