一、前言我站采用1957年由捷克进口的2500瓩机组,全站共有有汞差压计8台,内装水银共约40余公斤。由于检修散失,每年均要补充水银1～2公斤。大家知道,水银是一种易流失而不易回收,易蒸发而不易被人发觉,易被人吸收而不易排除的有毒物质。站上热工人员都曾有不同程度的中毒现象。同时,设备装在列车上,地方小,空气流通差,水银的散失不仅危害锅炉、汽机等人员的健康,而且污染环境,影响抓革命、促生产。鉴于上述情况,改革汞
I. Foreword I stand using 2500 瓩 units imported from Czech Republic in 1957. The station has a total of 8 sets of mercury differential pressure gauges, with a total of about 40 kg of mercury in it. As the maintenance loss, every year to add 1 to 2 kg of mercury. We all know that mercury is a kind of easy to drain and not easy to recover, easy to evaporate and not easy to be found, easily absorbed and not easily excluded by the toxic substances. The station workers have had varying degrees of poisoning. At the same time, the equipment is installed on the train. The place is small and the air circulation is poor. The loss of mercury not only endangers the health of boilers, steam turbines and other personnel, but also pollutes the environment and affects the revolution and production. In view of the above, the reform of mercury
