燃?xì)獍l(fā)電機(jī)組故障診斷的準(zhǔn)確性怎么判斷
根據(jù)故障分析和排除的原理來(lái)發(fā)現(xiàn)燃?xì)獍l(fā)電機(jī)組故障,提高故障發(fā)現(xiàn)的準(zhǔn)確性
According to the principle of fault analysis and troubleshooting to find the fault of gas generator set, improve the accuracy of fault discovery
當(dāng)發(fā)生故障時(shí),要注意從故障現(xiàn)象分析故障原因,根據(jù)原理分析結(jié)構(gòu)。當(dāng)故障發(fā)生時(shí),首先要考慮以下三個(gè)問題:(1)故障發(fā)生前發(fā)生了什么?(2)故障發(fā)生前,您做了哪些維護(hù)和維修工作?(3)你以前遇到過類似的情況嗎?你是怎么處理的?此外,如果允許機(jī)組在運(yùn)行過程中確定問題,則可以在運(yùn)行過程中確定問題。
In case of failure, it is necessary to analyze the cause of failure from the failure phenomenon and analyze the structure according to the principle. When a fault occurs, the following three problems should be considered first: (1) what happened before the fault occurs? (2) what maintenance and repair work did you do before the fault occurs? (3) have you encountered similar situations before? How did you deal with them? In addition, if the unit is allowed to determine the problem during operation, the problem can be determined during operation.
單元操作,例如,如果發(fā)現(xiàn)排氣溫度過高或突然一個(gè)氣缸排氣溫度變化大,應(yīng)首先在設(shè)備運(yùn)行條件下檢查各缸氣體調(diào)節(jié)器松散,排除氣體調(diào)節(jié)器不松的問題仍然存在,應(yīng)停止檢查點(diǎn)火系統(tǒng),如:火花塞和點(diǎn)火線圈等是否有問題;如果出現(xiàn)排氣溫度異常,應(yīng)區(qū)分是單缸還是全缸。如果是單缸異常,應(yīng)考慮儀表顯示是否異常,可通過測(cè)量熱電動(dòng)勢(shì)或?qū)Ь€倒置消除。如果這是一種全球異常,考慮是否有氣體濃度的變化或點(diǎn)火不良。
Unit operation, for example, if it is found that the exhaust temperature is too high or suddenly the exhaust temperature of a cylinder changes greatly, the gas regulator of each cylinder shall be checked for looseness under the operation condition of the equipment first, and the problem that the gas regulator is not loose shall be eliminated. The ignition system, such as spark plug and ignition coil, shall be checked for any problem; In case of abnormal exhaust temperature, it is necessary to distinguish between single cylinder and full cylinder. In case of single cylinder abnormality, whether the instrument display is abnormal shall be considered, which can be eliminated by measuring thermoelectric EMF or conducting wire inversion. If this is a global anomaly, consider whether there is a change in gas concentration or poor ignition.
在故障排除時(shí),當(dāng)沒有有效的方法找出故障原因時(shí),可以使用替代法。有疑問時(shí)點(diǎn)火控制器故障,例如,調(diào)整檢驗(yàn)和特殊點(diǎn)火控制器連接到PC或筆記本電腦程序員來(lái)調(diào)整,但基本上不能配置這些測(cè)試設(shè)備維護(hù)單元,然后你可以把其他備用設(shè)備上的點(diǎn)火控制器拆開機(jī)運(yùn)行后,通過觀察是否類似的故障再次發(fā)生,確定點(diǎn)火控制器是否損壞。
In troubleshooting, when there is no effective way to find out the cause of the fault, alternative method can be used. When in doubt, the ignition controller fails, for example, adjustment inspection and special ignition controller are connected to PC or laptop programmer for adjustment, but these test equipment maintenance units can not be configured basically. Then you can remove the ignition controller on other standby equipment for operation, and determine whether the ignition controller is damaged by observing whether similar failures occur again.
