日常保养试验台的重要事项

来源:http://www.sdrunjing.com/ 日期:2019-09-29 发布人:润静小编
  1、二次比较规则在动手检修之前已经明确了故障所在,或者已经确定了解决故障的方案。换句话说,动手之前已经找对了解决办法。

  The 1 and two rules of comparison, before the troubleshooting, have identified the fault, or have identified a solution to the fault. In other words, you've got the right solution before you start.

  更换了流动向后在正式进样前可以进两次标准品以检查保留时间的稳定情况和色谱峰的稳定性。在梯度洗脱中如果出现了多余的峰,可以空载梯度洗脱一次(真的有问题吗?),用此规则可以避免不必要的改变,尽快确定纠正措施。

  The flow is reversed and the two standard can be entered before the official sample is injected to check the stability of the retention time and the stability of the chromatographic peaks. If there is an excess peak in the gradient elution, the gradient can be removed without load (is there a problem? By this rule, unnecessary changes can be avoided and corrective actions can be determined as soon as possible.

  2、取代规则用好的部件换下可疑的部件,是查找故障的最好方法。如果你怀疑检测器引起了噪音,就换一个性能好的检测器。如果故障被排除了,就说明换下的检测器有问题。这个规则应用的规模有大有小,可以从换整个部件到换印刷线路板上的集成块。

  2, replacing the rules with good components to change the suspect parts is the best way to find the fault. If you suspect that the detector caused a noise, change a detector with good performance. If the fault is ruled out, it is indicated that the detector has been changed. The size of this rule is large and small, and it can be changed from the whole part to the block on the printed circuit board.

  3、换回规则这个规则和取代规则一起运用,好部件取代了可疑部件后情况并未得到改善,应重新换上原部件。这样做的维修费用最小,也防止了用过的部件积压下来。这条规则仅适用于单一的故障。换回原则不适用于以下的情况:

  3, in exchange for rules, this rule and replace the rules used together, good parts to replace the suspicious parts, the situation has not been improved, should be re replaced with the original components. Maintenance costs are minimal and the backlog of used components is prevented. This rule applies only to a single fault. The exchange principle does not apply to the following circumstances:

  1、在取下时新部件已损坏(如泵密封垫圈);

  1, the new components are damaged (such as pump seal washer);

  2、部件价格低(如柱内衬过滤片);

  2, low price parts (such as column lining filter);

  3、重新装上原部件要冒损坏的风险;

  3, to re install the original components, the risk of damage;

  4、定期更换的部件。

  4, regular replacement parts.
