燃氣發(fā)電機組常見的三個錯誤操作了解
很多客戶在使用燃氣發(fā)電機組時,由于對該發(fā)電機組的操作不熟悉而出現(xiàn)誤操作,很容易造成發(fā)電機組的損壞。因此,我們將在此詳述,并將這些容易出現(xiàn)的錯誤操作介紹如下:
When many customers use the gas-fired generator set, they are not familiar with the operation of the generator set and misoperation occurs, which is easy to cause damage to the generator set. Therefore, we will elaborate here and introduce these error prone operations as follows:
1、冷啟動后帶載運行不預(yù)熱
1. No preheating during on load operation after cold start
發(fā)電機冷啟動時,由于機油粘度高、流動性差,油泵供油不足,機器摩擦面因缺油潤滑不良,導致快速磨損和撕裂,甚至出現(xiàn)拉缸、燒瓦等故障。因此,燃氣發(fā)電機組冷卻啟動后,應(yīng)怠速運行升溫,待備用油溫達到40℃以上時帶載運行;機器應(yīng)低檔啟動,各檔依次行駛一段里程,直至油溫正常,供電正常。油量充足后,即可轉(zhuǎn)入正常行駛。
During the cold start of the generator, due to the high viscosity and poor fluidity of the engine oil, insufficient oil supply from the oil pump, and poor lubrication of the machine friction surface due to lack of oil, rapid wear and tear are caused, and even cylinder pulling, Bush burning and other faults occur. Therefore, after the gas generator unit is cooled and started, it shall run at idle speed for temperature rise, and operate with load when the standby oil temperature reaches more than 40 ℃; The machine shall be started at low gear, and each gear shall be driven for a certain mileage successively until the oil temperature is normal and the power supply is normal. When the fuel is sufficient, you can turn to normal driving.
2、帶負載緊急停機或突然卸載負載后立即停機
2. Emergency stop with load or stop immediately after sudden load unloading
燃氣發(fā)動機熄火后,冷卻系統(tǒng)水的循環(huán)停止,散熱能力急劇下降,受熱部位失去冷卻,容易造成缸蓋、缸套、缸體等部位過熱,導致卡在缸套中的活塞出現(xiàn)裂紋或過度膨脹。另一方面,如果燃氣發(fā)動機怠速不冷卻就停機,摩擦面將沒有足夠的油,當發(fā)電機重新啟動時,會因潤滑不良而加劇磨損。因此,應(yīng)在燃氣發(fā)動機熄火前卸荷,逐漸降低轉(zhuǎn)速,空載運行幾分鐘。
After the gas engine stalls, the water circulation of the cooling system stops, the heat dissipation capacity drops sharply, and the heated parts lose cooling, which is easy to cause overheating of the cylinder head, cylinder liner, cylinder block and other parts, resulting in cracks or excessive expansion of the piston stuck in the cylinder liner. On the other hand, if the gas engine is shut down without cooling at idle speed, there will not be enough oil on the friction surface. When the generator is restarted, the wear will be aggravated due to poor lubrication. Therefore, the gas engine shall be unloaded before flameout, the speed shall be gradually reduced, and the no-load operation shall be carried out for several minutes.
3、在油量不足時運行
3. Operation in case of insufficient oil
此時,供油不足會導致各摩擦副表面供油不足,造成異常磨損或燒傷。為此,必須在機器啟動前和發(fā)電機運轉(zhuǎn)過程中保證有足夠的機油,以防止因缺油而導致拉缸和燒瓦的故障。
At this time, insufficient oil supply will lead to insufficient oil supply on the surface of each friction pair, resulting in abnormal wear or burns. For this reason, it is necessary to ensure that there is enough oil before the machine is started and during the operation of the generator, so as to prevent cylinder pulling and Bush burning caused by lack of oil.

Relevant methods and measures are as follows:
防范措施
Preventive measures
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)?,F(xiàn)場查看燃氣發(fā)電機冷卻風扇的運轉(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扇電機殼和氣缸進行溫度檢測。
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. Check the speed, frequency, outlet voltage, power, oil pressure, cooling water temperature, battery voltage and other parameters of the gas generator. 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.
參考廠商提供的燃氣發(fā)電機組維保手冊,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。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。
Refer to the maintenance manual of gas generator set provided by the manufacturer, and combine with the actual operation experience on site, formulate and strictly implement the compliant maintenance procedures. 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.
