文章编号: 72696点击此处访问英文版本文章
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

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
- 拧紧管路。
- 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)。
- 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。
