waters UPLC液相 泵报错复位失败的原因？

菜鸟博士Caesar

pump h/w home fault（4） 且communication failure

硬件故障的话是泵马达的问题。

此外：

故障描述

• 初始化期间出现 Pump H/W Homing Error (3)（泵硬件复位错误 (3)）消息

• 拆下泵头后，电机初始化成功

环境

• ACQUITY UPLC H-Class Bio

• ACQUITY UPLC H-Class

原因
反压或物理限制的阻力限制了蓄积泵头的移动

解决方法

1. 拆下泵头并确认可以自由移动。

2. 清洗柱塞装置、泵头和泵弹簧，去除沉淀物堆积。

3. 重新初始化仪器，验证问题是否已解决。

SYMPTOMS

• Pump H/W Homing Error (3) occurs during initialization

• Removing pump head brings successful initialization of motor

ENVIRONMENT

• ACQUITY UPLC H-Class Bio

• ACQUITY UPLC H-Class

CAUSE
Restriction of accumulator pump head movement due to resistance from back pressure or physical restriction

FIX or WORKAROUND

1. Remove the pump head and confirm free travel.

2. Clean the plunger assembly, head, and pump springs to remove buildup of precipitates.

3. Reinitialize the instrument to verify that the issue is resolved.
