燃?xì)獍l(fā)電機(jī)組停機(jī)前的必做事項(xiàng)主要包括以下幾個(gè)方面：

　　The necessary precautions before shutting down a gas generator set mainly include the following aspects:

　　一、卸去負(fù)荷與冷卻機(jī)組

　　1、 Remove the load and cooling unit

　　卸去負(fù)荷：在停機(jī)前，必須先卸去機(jī)組的全部負(fù)荷，確保機(jī)組處于空載狀態(tài)。這可以通過(guò)逐步關(guān)閉連接到發(fā)電機(jī)組的負(fù)載設(shè)備或逐漸減少負(fù)荷來(lái)實(shí)現(xiàn)，避免突然卸載導(dǎo)致的機(jī)組不穩(wěn)定。

　　Unloading load: Before shutting down, all loads of the unit must be unloaded to ensure that the unit is in an unloaded state. This can be achieved by gradually shutting down the load devices connected to the generator set or gradually reducing the load to avoid unit instability caused by sudden unloading.

　　冷卻機(jī)組：在空載狀態(tài)下，讓機(jī)組繼續(xù)運(yùn)行一段時(shí)間，以便機(jī)組得到充分冷卻。特別是對(duì)于配置增壓器的機(jī)組，當(dāng)水溫、油溫降至適宜溫度（如60℃以下）時(shí)，還需再空載運(yùn)行一段時(shí)間（如5分鐘），以確保增壓器進(jìn)一步冷卻，防止結(jié)膠、結(jié)碳和漏油現(xiàn)象。

　　Cooling unit: Keep the unit running for a period of time under no-load condition to ensure sufficient cooling. Especially for units equipped with a turbocharger, when the water and oil temperatures drop to a suitable temperature (such as below 60 ℃), they need to run without load for a period of time (such as 5 minutes) to ensure further cooling of the turbocharger and prevent glue, carbon, and oil leakage.

　　二、檢查控制系統(tǒng)與參數(shù)

　　2、 Check the control system and parameters

　　檢查控制系統(tǒng)：在停機(jī)前，需要檢查燃?xì)獍l(fā)電機(jī)組的控制系統(tǒng)是否正常工作，確?？刂破辽系母黜?xiàng)指示燈顯示正常，無(wú)異常報(bào)警信息。

　　Check the control system: Before shutting down, it is necessary to check whether the control system of the gas generator set is working properly, ensuring that all indicator lights on the control screen are displaying normally and there are no abnormal alarm messages.

　　觀察機(jī)組參數(shù)：觀察機(jī)組的水溫、油溫、油壓等參數(shù)，確保其在正常范圍內(nèi)。如有異常，應(yīng)及時(shí)處理。

　　Observe unit parameters: Observe the water temperature, oil temperature, oil pressure, and other parameters of the unit to ensure that they are within the normal range. If there are any abnormalities, they should be dealt with promptly.

　　三、準(zhǔn)備停機(jī)操作

　　3、 Prepare for shutdown operation

　　通知相關(guān)人員：在停機(jī)前，應(yīng)通知相關(guān)人員，確保他們了解停機(jī)時(shí)間和原因，以便做好相應(yīng)的準(zhǔn)備工作。

　　Notify relevant personnel: Prior to shutdown, relevant personnel should be notified to ensure they understand the downtime and reasons, in order to prepare accordingly.

　　準(zhǔn)備停機(jī)工具：確保所需的停機(jī)工具（如停機(jī)按鈕、急停按鈕等）處于可用狀態(tài)。

　　Prepare shutdown tools: Ensure that the required shutdown tools (such as shutdown buttons, emergency stop buttons, etc.) are in a usable state.

　　四、執(zhí)行停機(jī)程序

　　4、 Execute shutdown program

　　按下停機(jī)按鈕：在控制屏上按下停機(jī)按鈕，啟動(dòng)機(jī)組的停機(jī)程序。在停機(jī)過(guò)程中，機(jī)組會(huì)自動(dòng)切斷燃?xì)夤?yīng)，并關(guān)閉相關(guān)閥門和開(kāi)關(guān)。

　　Press the shutdown button: Press the shutdown button on the control screen to start the shutdown program of the unit. During the shutdown process, the unit will automatically cut off the gas supply and close the relevant valves and switches.

　　觀察機(jī)組狀態(tài)：在停機(jī)過(guò)程中，應(yīng)密切觀察機(jī)組的運(yùn)行狀態(tài)，確保機(jī)組能夠平穩(wěn)地停機(jī)，無(wú)異常聲響和振動(dòng)。

　　Observing the status of the unit: During the shutdown process, the operating status of the unit should be closely monitored to ensure that it can be shut down smoothly without any abnormal sounds or vibrations.

　　五、停機(jī)后的注意事項(xiàng)

　　5、 Precautions after shutdown

　　等待機(jī)組完全停止：等待機(jī)組完全停止后，關(guān)閉控制屏的電源，并切斷機(jī)組的總電源。

　　Wait for the unit to come to a complete stop: After the unit comes to a complete stop, turn off the power supply to the control panel and cut off the main power supply to the unit.

　　檢查機(jī)組狀態(tài)：在停機(jī)后，應(yīng)檢查機(jī)組的狀態(tài)，確保機(jī)組無(wú)異?，F(xiàn)象。如有異常，應(yīng)及時(shí)處理。

　　Check the status of the unit: After shutdown, the status of the unit should be checked to ensure that there are no abnormal phenomena. If there are any abnormalities, they should be dealt with promptly.

　　清理機(jī)組：對(duì)機(jī)組進(jìn)行清理，清除機(jī)組表面的灰塵和雜物。同時(shí)，還需對(duì)機(jī)組的進(jìn)風(fēng)口和出風(fēng)口進(jìn)行清理，確保通風(fēng)暢通。

　　Cleaning the unit: Clean the unit to remove dust and debris from its surface. At the same time, it is necessary to clean the air inlet and outlet of the unit to ensure smooth ventilation.

　　維護(hù)保養(yǎng)：定期對(duì)燃?xì)獍l(fā)電機(jī)組進(jìn)行維護(hù)保養(yǎng)，檢查機(jī)組的各項(xiàng)性能指標(biāo)是否正常。如發(fā)現(xiàn)問(wèn)題，應(yīng)及時(shí)處理，確保機(jī)組的正常運(yùn)行。

　　Maintenance: Regularly maintain the gas generator set and check whether its various performance indicators are normal. If any problems are found, they should be dealt with in a timely manner to ensure the normal operation of the unit.

　　綜上所述，燃?xì)獍l(fā)電機(jī)組停機(jī)前的必做事項(xiàng)涉及負(fù)荷卸載、機(jī)組冷卻、控制系統(tǒng)檢查、參數(shù)觀察、停機(jī)準(zhǔn)備、停機(jī)程序執(zhí)行以及停機(jī)后的檢查與維護(hù)等多個(gè)方面。這些步驟的嚴(yán)格執(zhí)行有助于確保機(jī)組的安全停機(jī)，延長(zhǎng)機(jī)組的使用壽命，并提高發(fā)電效率。

　　In summary, the necessary tasks before shutting down a gas generator unit include load unloading, unit cooling, control system inspection, parameter observation, shutdown preparation, shutdown program execution, and post shutdown inspection and maintenance. The strict implementation of these steps helps ensure the safe shutdown of the unit, extend its service life, and improve power generation efficiency.
