为解决新购置电炉变压器油水冷却器罐打压试漏时油水四流、有害杂质也无法去除干净的问题,中信锦州金属股份有限公司对油水冷却器打压试漏进行工艺改善。一是取下罐体下面的放油、放水丝堵,制作带有4分阀门和丝头的放油、放水装置,一头安装在罐体上,另一头用于连接油泵管、放水肢管,试漏后可以用小油泵抽出变压器油和内部杂质,同时连接放水胶管 In order to solve the problem of fresh water, oil and water in the newly-purchased electric oil cooler tank of oil-fired transformers, the fourth-order oil and water can not be removed when harmful leakage of impurities can not be removed. CITIC Jinzhou Metal Co., Ltd. improved the process of suppressing the leakage of oil-water coolers. First, remove the tank below the oil, drain plug wire, with a 4-point valve and the head of the drain, drain device, one installed in the tank, the other end is used to connect the pump tube, drain the limbs, After the leak can be used to extract the small oil pump transformer oil and internal impurities, while connecting the drain hose
