蒸汽机车锅炉的洗炉作业,历来是由洗炉工人钻入炉内,用压力为6～8公斤/厘米~2的水进行冲洗,以去除锅筒各部位的浮锈和软泥。由于锅筒内工作面窄,操作困难,且温度在30～40℃,劳动条件恶劣,有害于工人的身体健康,同时,洗炉质量亦难以保证。为了改变这种落后的洗炉方法,不少路局的机务段采用了一种电气控制的自动洗炉装置。它是在洗修道上安设30～40根胶管,冲洗时由人工把胶管接装到洗炉堵处,洗好后再由人工卸 Steam locomotive boiler wash operation, has always been bake furnace workers into the furnace, with pressure of 6 ~ 8 kg / cm ~ 2 water to wash, to remove all parts of the drum rust and slime. As the working surface of the drum is narrow, the operation is difficult, and the temperature is between 30 and 40 DEG C, the working conditions are harsh, which is detrimental to the health of the workers. At the same time, the quality of the washing oven is also hard to guarantee. In order to change this backward method of washing stoves, many locomotive depots use an electrically controlled automatic wash-off device. It is installed in the wash Road, 30 to 40 hose, flushing when manually by the hose installed to the wash block, washed by the manual unloading
