锅炉水垢对蒸汽机车的危害,主要是:浪费燃料、缩短锅炉的使用寿命和不安全。控制水垢结生的方法,通常是在炉水中放水处理剂。由于给水质量和机车运行、保养状态的不同,水处理剂的投放量是需要调整的。为了正确掌握水垢增长率和保证机车在允许的水垢厚度下运行,必须经常了解水垢的厚度。对水垢厚度的测定,目前各段仍采用在机车洗修时由专人目测的方法,完全靠目测人员的经验,准确性差。我所与上海铁路局机务处、化验所、南翔机务段、常州无 Boiler scale on the steam locomotive hazards, mainly: waste of fuel, shorten the life of the boiler and unsafe. The method of controlling scale formation is usually a water treatment agent in the boiler water. Due to the quality of water supply and locomotive running, maintenance status of different, water treatment agent dosage is to be adjusted. In order to properly grasp the rate of scale growth and to ensure that the locomotive operates at the allowable scale thickness, the scale thickness must always be known. The determination of the thickness of the scale, the current paragraph is still used in locomotive washing by hand when the visual approach, entirely by the visual experience of staff, the accuracy is poor.
