防爆电机使用在具有爆炸性混合物的环境中,这些爆炸性混合物具有一定的腐蚀性,对防爆外壳有不同程度的腐蚀,防爆零件的隔爆面被腐蚀,将使隔爆间隙发生变化而使隔爆性能变化,严重者将导致电机不能防爆。所以隔爆面防腐防锈是一个重大问题,本课题的目的就是研制一种适用于防爆电机防爆零件的防腐蚀铸铁。本课题由南阳防爆电机厂、郑州机械研究所、南阳防爆电气研究所合作研制,经一年多时间,目前已取得初步成果,并通过
Explosion-proof motor used in an explosive mixture of the environment, these explosive mixtures have a certain corrosive, the explosion-proof shell have different degrees of corrosion, explosion-proof parts of the explosion-proof surface is corrosive, explosion-proof gap will change so that explosion-proof performance Changes, serious cases will lead to electrical explosion-proof. Therefore, the anti-corrosion explosion-proof surface is a major issue, the purpose of this project is to develop a suitable anti-corrosion explosion-proof motor parts cast iron. The subject by Nanyang explosion-proof motor factory, Zhengzhou Institute of Machinery, Nanyang Institute of explosion-proof electrical cooperation in research and development, after more than a year, has achieved initial results, and through
