燃氣發(fā)電機組故障的診斷及防范建議
燃氣發(fā)電機組運行過(guò)程安全環(huán)保,有效降低了污染物的排放,運行時(shí)須采取有效的措施予以防范,并做到發(fā)生故障及時(shí)處理與解決,盡量避免發(fā)電機組出現故障問(wèn)題,下面來(lái)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(jìn)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(shù)狀態(tài)觀(guān)察故障情況是否發(fā)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(chǎn)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(jìn)行檢測,檢查機組水溫及機組負荷是否正常一旦發(fā)生無(wú)法滿(mǎn)負荷運行的現象,必須及時(shí)進(jìn)行原因分析,排查進(jìn)氣系統是否存在堵塞現象,并對計量閥旁通閥等進(jìn)行檢測,根據運行參數合理進(jìn)行檢測與判斷如機組負荷超范圍擺動(dòng),應檢查此現象是否由單缸或多缸的點(diǎn)火存在問(wèn)題引起的,及時(shí)發(fā)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(shí)思想混亂,都會(huì )導致無(wú)法及時(shí)解決故障維修人員應對常見(jiàn)的故障及發(fā)生原因進(jìn)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(shí)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(guò)一千小時(shí)必須進(jìn)行保養對氣門(mén)間隙以及過(guò)橋進(jìn)行調整,清洗曲軸箱的呼吸器,及時(shí)進(jìn)行充電機及皮帶的檢查,檢測各個(gè)水泵水油管路系統及排氣系統,還要對電氣系統進(jìn)行保養,及時(shí)發(fā)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(fā)電機常見(jiàn)的故障即產(chǎn)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(shí)排除才能保證機組的正常運行。您有問(wèn)題或者需求就來(lái)我們網(wǎng)站http://m.elmasticar.com咨詢(xún)查看了解吧!
Only when we have a comprehensive and in-depth understanding of the common faults of the gas generator, that is, the causes, can we quickly find out the causes and eliminate them in time once the unit fails, can we ensure the normal operation of the unit.
