生產(chǎn)運營過程中難免會遇到燃氣發(fā)電機意外停機現(xiàn)象，對故障問題的精準判斷直接關(guān)系到生產(chǎn)經(jīng)營活動的恢復(fù)快慢，等等一些問題會出現(xiàn)，那么需要怎么防治呢？

During the production and operation process, it is inevitable to encounter unexpected shutdown of gas generator. The accurate judgment of fault problems is directly related to the recovery speed of production and operation activities. Some problems will occur, so how to prevent them?

加強日常巡檢

Strengthen daily inspection

每日定點巡檢，檢查機組的各項參數(shù)，上位機系統(tǒng)可設(shè)置報警值。檢查燃氣發(fā)電機的轉(zhuǎn)速、頻率、出口電壓、功率、機油壓力、冷卻水溫度以及蓄電池電壓等參數(shù)。

Daily fixed-point patrol inspection, focusing on the inspection of various parameters of the unit, and the upper computer system can set the alarm value. The speed, frequency, outlet voltage, power, oil pressure, cooling water temperature, battery voltage and other parameters of the gas generator shall be mainly checked.

現(xiàn)場查看燃氣發(fā)電機冷卻風(fēng)扇的運轉(zhuǎn)情況，冷卻水管路和機油管路的滲漏情況，同時查看機油液位和冷卻水液位?，F(xiàn)場辨聽燃氣發(fā)電機運行時有無異常聲響。手持測溫槍對冷卻風(fēng)扇電機殼和氣缸進行溫度檢測。

Check the operation of the cooling fan of the gas generator, the leakage of the cooling water pipe and oil pipe, and check the oil level and cooling water level at the same time. Identify whether there is abnormal sound when the gas generator is running on site. Hold a temperature measuring gun to detect the temperature of the cooling fan motor housing and cylinder.

維護保養(yǎng)

Maintenance

參考廠商提供的燃氣發(fā)電機維保手冊，結(jié)合現(xiàn)場實際運營經(jīng)驗，制定并嚴格執(zhí)行合規(guī)的維保規(guī)程。維保級別一般有首保，500h維保，1000h維保，2000h維保，4000h維保，8000h維保以及中修和大修維保。

Refer to the gas generator maintenance manual provided by the manufacturer and in combination with the actual operation experience on site, formulate and strictly implement the compliant maintenance procedures. Maintenance levels generally include first maintenance, 500h maintenance, 1000h maintenance, 2000h maintenance, 4000H maintenance, 8000h maintenance, and medium and overhaul maintenance.

不同的維保級別對應(yīng)不同的項目檢查和部件更換。維保要做到全面，檢查氣門間隙，氣門凸出量調(diào)整，曲軸箱呼吸器清潔，火花塞檢查，正時傳感器清潔，延時繼電器和其他電氣元件的檢查，水路和油路的檢查等。同時，控制系統(tǒng)接線松緊度以及各傳感器探頭的檢查校準。

Different maintenance levels correspond to different item inspections and component replacement. The maintenance shall be comprehensive, focusing on valve clearance, valve projection adjustment, crankcase breather cleaning, spark plug inspection, timing sensor cleaning, time delay relay and other electrical components inspection, water and oil circuit inspection, etc. At the same time, the tightness of the wiring of the control system and the inspection and calibration of each sensor probe.

意外事件記錄分析

Accident record analysis

在燃氣發(fā)電機組運行過程中，注重常見故障和其他故障的分類總結(jié)、歸類，制定一套事件應(yīng)急處置卡，針對不同的故障類型編制不同的操作要求及部件更換。經(jīng)過長期的意外停機事件積累，對于燃氣發(fā)電機的故障處理能力會有明顯的提升。

During the operation of gas-fired generator units, attention shall be paid to the classification, summary and classification of common faults and other faults, a set of emergency response cards shall be developed, and different operation requirements and component replacement shall be prepared for different fault types. After the accumulation of long-term unexpected shutdown events, the fault handling capacity of gas generator will be significantly improved.

加強人員培訓(xùn)考核加強站場相關(guān)人員對燃氣發(fā)電機的掌握，逐步提高意外停機事件的應(yīng)急響應(yīng)機制和處理能力。通過崗位練兵和培訓(xùn)考核，保證人員對燃氣發(fā)電機的熟悉掌握。同時，可以定期舉辦人員交流，分享彼此燃氣發(fā)電機運維經(jīng)驗。

Strengthen personnel training and assessment, strengthen the mastery of gas generator by relevant personnel in the station, and gradually improve the emergency response mechanism and handling capacity of unexpected shutdown events. Through on-the-job training and training assessment, ensure that professionals are familiar with gas generators. At the same time, regular personnel exchanges can be held to share each other's experience in gas generator operation and maintenance.
