燃氣發電機組運行過程安全環保，有效降低了污染物的排放，運行時須采取有效的措施予以防范，并做到發生故障及時處理與解決，盡量避免發電機組出現故障問題，下面來看看它的故障的診斷及防范建議。

The gas-fired generator unit is safe and environmentally friendly during operation, effectively reducing the emission of pollutants. Effective measures must be taken to prevent the operation, and timely handle and solve the failure, so as to avoid the failure of the generator unit as much as possible. Let's take a look at its fault diagnosis and prevention suggestions.

故障診斷的方法

Methods of fault diagnosis

（1）部分停止法。停止疑似造成故障部位的工作看故障是否消失以驗證判斷是否正確。

(1) Partial stop method. Stop the work of the part suspected of causing the fault to see if the fault disappears to verify whether the judgment is correct.

（2）比較法。更換可能造成故障的部件，然后對更換前后的故障現象進行比較，以確定或排除判斷。

(2) Comparative method. Replace the components that may cause the fault, and then compare the fault phenomena before and after the replacement to determine or eliminate the judgment.

（3）試探法。改變某些系統的技術狀態觀察故障情況是否發生變化。

(3) Heuristics. Change the technical status of some systems and observe whether the fault condition changes.

（4）拆檢法。對可能造成故障部位或部件拆卸檢查，分析產生故障的具體原因。

(4) Disassembly and inspection method. Disassemble and inspect the parts or components that may cause the fault, and analyze the specific causes of the fault.

故障的防范建議

Fault prevention suggestions

除了每日的巡檢以外，還要對機組的參數進行檢測，檢查機組水溫及機組負荷是否正常一旦發生無法滿負荷運行的現象，必須及時進行原因分析，排查進氣系統是否存在堵塞現象，并對計量閥旁通閥等進行檢測，根據運行參數合理進行檢測與判斷如機組負荷超范圍擺動，應檢查此現象是否由單缸或多缸的點火存在問題引起的，及時發現安全隱患并予以合理解決。

In addition to daily patrol inspection, the parameters of the unit shall also be inspected to check whether the water temperature and load of the unit are normal. Once the phenomenon that the unit cannot operate at full load occurs, the cause analysis must be carried out in time to check whether the air intake system is blocked, and the bypass valve of the metering valve shall be inspected. The detection and judgment shall be carried out reasonably according to the operating parameters. If the unit load swings beyond the range, It is necessary to check whether this phenomenon is caused by the ignition problems of single cylinder or multi cylinder, and timely find out and reasonably solve the safety hazards.

機組能否正常運行取決于故障的排除與解決速度如果檢修人員不了解機組結構及運行原理，故障排查時思想混亂，都會導致無法及時解決故障維修人員應對常見的故障及發生原因進行分析與匯總，明確具體的診斷方法及解決方案，及早解決故障，減少故障機組的停機時間。

The normal operation of the unit depends on the speed of troubleshooting and solution. If the maintenance personnel do not understand the structure and operation principle of the unit and have confused thoughts during troubleshooting, they will not be able to solve the fault in time. The maintenance personnel shall analyze and summarize the common faults and their causes, identify the specific diagnosis methods and solutions, solve the faults as soon as possible and reduce the downtime of the faulty unit.

機組運行每超過一千小時必須進行保養對氣門間隙以及過橋進行調整，清洗曲軸箱的呼吸器，及時進行充電機及皮帶的檢查，檢測各個水泵水油管路系統及排氣系統，還要對電氣系統進行保養，及時發現安全隱患。

The unit must be maintained every 1000 hours of operation, the valve clearance and the bridge must be adjusted, the respirator of the crankcase should be cleaned, the charger and belt should be inspected in time, the water and oil pipeline system and exhaust system of each water pump should be tested, and the electrical system should be maintained to find out the potential safety hazards in time.

只有對燃氣發電機常見的故障即產生的原因做到全面深入了解，一旦機組出現故障能夠快速查明原因并及時排除才能保證機組的正常運行。您有問題或者需求就來我們網站http://www.hdlelisa.com咨詢查看了解吧！
