压力波动大;泵的动态渗漏测试失败 - WKB72696

故障描述

  • 压力波动值很高(压力回读的 10% 以上)
  • 蓄积泵或初级泵渗漏测试失败
  • 管路接头处可见泄漏

环境

  • ACQUITY UPLC H-Class QSM
  • ACQUITY UPLC H-Class QSM Bio
  • ACQUITY UPLC
  • ACQUITY UPLC BSM
  • ACQUITY UPLC H-Class
  • ACQUITY UPLC H-Class Bio
  • ACQUITY UPLC I-Class
  • ACQUITY UPLC H-Class PLUS
  • ACQUITY UPLC H-Class PLUS Bio
  • ACQUITY UPLC I-Class PLUS
  • ACQUITY UPLC M-Class
  • ACQUITY Premier

原因

泵头上的管路/接头渗漏;

  • 蓄积泵传感器与排放阀之间的管路渗漏
  • 连接初级泵传感器和蓄积泵单向阀的管路渗漏。

解决方法

  1. 拧紧管路。
  2. 如果拧紧后仍然存在渗漏,则更换管路(部件号因 QSM 类型而异)。
  3. 检查压力稳定性,执行渗漏测试,验证问题是否已解决。

附加信息

其他地方可能存在泄漏,因此在更换泵头之前,最好先检查所有连接是否有渗漏和/或腐蚀迹象。
