["펌프 부품 두 번째 압력 테스트에서 泵零件二次测试泄露问题"

2019-06-06View Original

Thread Content

"공장에서 펌프 조립 전에 부품에 압력을 가하여 결함이 없는지 확인합니다. 현재의 문제는 부품이 압력 테스트를 통과했지만 조립 후 전체 펌프의 정압 테스트에서 여전히 泄漏。铸铁、铸钢都出现了这种情况请教各位这是啥情况?如何控制?(工厂为了降低成本选择了不太好的供应商,而且在无损检测这块也没有)"

"부품 압력 테스트 시의 압력 값과 보전 시간은 전체 기계의 압력 테스트 시의 압력 값과 보전 시간과 같습니다가?如果后者低,则应该是零部件压 力测试存在泄漏而没有检查出来"

"정압 테스트를 통과 못하면 펌프는 泄漏吗?"

" 泄漏是工艺水平问题,隐秘的比如应力变形、铸造缺陷、砂眼等之类的。工艺问题比如密封面平面精度差或者粗糙度之类的。"

"还有一个,盘根填料密封的泵有标准,是允许 泄漏的。"
