(续上期)乙炔发生器的安全使用应注意以下几点。1.必须安装符合要求的回火防止器。多台乙炔发生器的汇气总管与每台乙炔发生器之间,必须设有回火防止器;接至车间的乙炔管道,必须设有回火防止器;每个焊接工须有独立的工作岗位回火防止器。2.中压式乙炔发生器上,应有压力表和符合安全的泄压防爆膜。3.要按照规定使用粒度大小适当的电石,禁止使用含磷化物超过容许限量的杂质(如矽铁等)、太多的电石和粒度
(Continued) Safety of acetylene generators should pay attention to the following points. 1. Must be installed to meet the requirements of the tempering prevention device. There must be a tempering preventer between the manifold of multiple acetylene generators and each acetylene generator. An acetylene pipe connected to the workshop must be provided with a tempering preventer. Each welder must work independently Post tempering preventer. 2. Medium-pressure acetylene generator, there should be pressure gauge and pressure relief explosion-proof membrane in line with safety. 3. In accordance with the provisions of the use of appropriate size carbide, prohibit the use of phosphide exceeds the allowable limits of impurities (such as ferrosilicon, etc.), too much calcium carbide and particle size
