燃气麻豆性视频网停机前的必做事项主要包括以下几个方面：

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

　　一、卸去负荷与冷却机组

　　1、 Remove the load and cooling unit

　　卸去负荷：在停机前，必须先卸去机组的全部负荷，确保机组处于空载状态。这可以通过逐步关闭连接到麻豆性视频网的负载设备或逐渐减少负荷来实现，避免突然卸载导致的机组不稳定。

　　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.

　　冷却机组：在空载状态下，让机组继续运行一段时间，以便机组得到充分冷却。特别是对于配置增压器的机组，当水温、油温降至适宜温度（如60℃以下）时，还需再空载运行一段时间（如5分钟），以确保增压器进一步冷却，防止结胶、结碳和漏油现象。

　　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、检查控制系统与参数

　　2、 Check the control system and parameters

　　检查控制系统：在停机前，需要检查燃气麻豆性视频网的控制系统是否正常工作，确保控制屏上的各项指示灯显示正常，无异常报警信息。

　　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.

　　观察机组参数：观察机组的水温、油温、油压等参数，确保其在正常范围内。如有异常，应及时处理。

　　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、准备停机操作

　　3、 Prepare for shutdown operation

　　通知相关人员：在停机前，应通知相关人员，确保他们了解停机时间和原因，以便做好相应的准备工作。

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

　　准备停机工具：确保所需的停机工具（如停机按钮、急停按钮等）处于可用状态。

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

　　四、执行停机程序

　　4、 Execute shutdown program

　　按下停机按钮：在控制屏上按下停机按钮，启动机组的停机程序。在停机过程中，机组会自动切断燃气供应，并关闭相关阀门和开关。

　　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.

　　观察机组状态：在停机过程中，应密切观察机组的运行状态，确保机组能够平稳地停机，无异常声响和振动。

　　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、停机后的注意事项

　　5、 Precautions after shutdown

　　等待机组完全停止：等待机组完全停止后，关闭控制屏的电源，并切断机组的总电源。

　　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.

　　检查机组状态：在停机后，应检查机组的状态，确保机组无异常现象。如有异常，应及时处理。

　　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.

　　清理机组：对机组进行清理，清除机组表面的灰尘和杂物。同时，还需对机组的进风口和出风口进行清理，确保通风畅通。

　　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.

　　维护保养：定期对燃气麻豆性视频网进行维护保养，检查机组的各项性能指标是否正常。如发现问题，应及时处理，确保机组的正常运行。

　　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.

　　综上所述，燃气麻豆性视频网停机前的必做事项涉及负荷卸载、机组冷却、控制系统检查、参数观察、停机准备、停机程序执行以及停机后的检查与维护等多个方面。这些步骤的严格执行有助于确保机组的安全停机，延长机组的使用寿命，并提高发电效率。

　　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.
