一、割炬的维修割炬是氧-乙炔火焰进行切割的主要工具,其作用是使可燃气体与氧气混合后,形成一定热能和形状的预热火焰,并能在预热火焰中心喷射切割氧气流,以便进行切割。目前在我国使用最普遍的是射吸式割炬。这种割炬在工作一段时间后,往往会使火焰能率下降,造成切割困难,且会出现异常回火现象。这时应拆开割炬,用细钢丝通顺乙炔气管路、射吸 First, the torch cutting torch is oxy-acetylene flame cutting the main tool, its role is to make the combustible gas and oxygen mixed to form a certain heat and shape of the preheating flame, and can be preheated in the center of the flame spray cutting oxygen Flow for cutting. Currently used in our country is the most common suction cutting torch. Such cutting torch after working for a period of time, often will reduce the rate of flame, resulting in cutting difficulties, and there will be abnormal tempering. At this time should be open torch, thin wire smooth acetylene gas pipeline, suction
