Briefly describe the five maintenance principles of cryogenic centrifuges
In general, for the maintenance of cryogenic centrifuges, we tend to follow four principles: one rule, two comparison rules, substitution rules, exchange rules, and reference condition rules, among which:
1. Replacement rules: replacing a suspicious part with a good one is the best way to find the fault. If you suspect that the detector is causing noise, switch to a good performance detector. If the fault is eliminated, there is a problem with the replaced detector. The scale of this rule application is large and small, from changing the entire part to replacing the integrated blocks on the printed circuit board.
2, exchange rules: exchange rules can be used together with the replacement rules, the good parts have replaced the suspicious parts of the cryogenic centrifuge, the situation has not been improved, should be replaced with the original parts. This has the least cost of repairs and prevents the backlog of used parts. This rule only applies to a single fault.
3. One rule: When the cryogenic centrifuge fails, you can tentatively change some states and change one parameter at a time. Do some simple changes and maybe solve the problem.
4, the second comparison rule: the fault has been identified before the hands-on maintenance, or has determined the solution to solve the problem, in other words, the solution has been found before the hands-on, this rule can be used to examine the situation after the system change, use This rule can avoid unnecessary changes and determine corrective actions as soon as possible.
5. Reference condition rules: There are two main types of reference condition rules: standard reference conditions and test reference conditions. Among them, standard reference conditions are also called standard test conditions, from one system to another, from one laboratory to one. Another laboratory is easy to verify conditions. The data measured with this condition helps identify problems between actual tests and systems. This article was edited by the laboratory instrument - Hunan Gilson Technology Development Co., Ltd.
