随着电力工业的迅速发展,火电站的大容量、高参数机组的不断投入,对操作系统和事故照明采用的直流电源的检修质量要求也越来越高,每次蓄电池组的大、小修都要进行铅极板的焊接。下面谈谈采用氧-乙炔焰焊接铅极板的一点体会。 1.焊前准备 (1)清理焊接表面用汽油及丙酮洗去焊接表面的油污,用100号砂布轻擦并使其露出金属光泽。如焊接表面凹凸不平,则需用刮刀刮去凹处的污垢物。 (2)制作焊丝将废旧铅极板或旧铅皮
With the rapid development of the power industry, high-capacity and high-parameter generating units of the thermal power station are continuously put into operation, and the quality requirements for the maintenance of the DC power used by the operating system and accident lighting are also getting higher and higher. Each time the battery pack is repaired, To carry out the welding of lead plate. Here to talk about the use of oxygen - acetylene flame welding lead plate experience. 1. Preparation before welding (1) to clean the welding surface with gasoline and acetone to wash off the oil surface of the weld, with a 100 # emery cloth gently rub and make it reveal the metallic luster. If the welding surface is uneven, you need to use a scraper to scrape the dirt of the recess. (2) the production of wire will be scrapped lead plate or old lead
