【摘要】 屏蔽泵冷却水管屏蔽泵对接的管板焊缝在制造和运行阶段发生过的缺陷,会导致焊缝变薄或破损泄漏,使冷却水管降低对屏蔽泵降温或失效。以致引起屏蔽泵的损坏。而渗透检测能有效检测出焊缝及其热影响区的细小缺陷,保证冷却水管正常运行。更多还原

【Abstract】 The defects of the welds connecting the cooling pipe with the tube plate of the canned motor pump in the manufacturing and operation stage will lead to the thinning of welds or the damage and leakage of them,which will reduce or fail the cooling effect of the cooling pipe and then cause the damage of the canned motor pump.However,the penetration detection can effectively detect the fine defects of the welds and its heat affected zone,so as to ensure the normal operation of the cooling water pipe.更多还原
