What are some matters needing attention when the gas generator unit is shut down at 600kW? Users often think that shutdown is not a button problem, so they often ignore the precautions for unit shutdown. Jichai Huanneng introduces the matters needing attention when the gas generator unit is shut down at 600 kW.

1、卸载：

1. Uninstall:

燃气发电机组600kw停机前，要先卸去负荷。

Before the gas generator unit is shut down at 600kW, the load shall be removed first.

2、怠速运行:

2. Idle operation:

额定转速下运行几分钟，初步冷却后，再将怠速/额定转换开关置于“怠速”位置，使机组怠速运行.使其水温和油温降下来。

Operate at the rated speed for several minutes. After initial cooling, place the idle / rated change-over switch in the "idle" position to make the unit operate at idle speed and reduce its water and oil temperature.

3、切断气源：

3. Cut off the air supply:

当机组“水温”、降低到60℃以下后，关闭手动燃气阀门。剩余的燃气可使机组继续运行1、2分钟，燃气耗尽后，机组将自动停机。

When the "water temperature" of the unit drops below 60 ℃, close the manual gas valve. The remaining gas can keep the unit running for 1 or 2 minutes. After the gas is exhausted, the unit will shut down automatically.

注意：

be careful:

对于配置增压器的机组，水温、油温降至60℃时不能接着关气、停机，应再空载运行5分钟，使增压器进一步冷却。否则会造成增压器漏油。

For the unit equipped with supercharger, when the water temperature and oil temperature drop to 60 ℃, it is not allowed to turn off the gas and stop the machine. It shall run no-load for another 5 minutes to further cool the supercharger. Otherwise, the supercharger will leak oil.

4、停机后，将控制屏面板上的钥匙关毕。

4. After shutdown, turn off the key on the control panel.

5、除发生飞车或工作场所出现易燃气等意外事故，正常情况下严禁带负荷停机。

5. In addition to flying cars or accidents such as flammable gas in the workplace, it is strictly prohibited to shut down with load under normal circumstances.

6、若停车后需要长期封存，应将机组的冷却水和机油放净，将机组表面处理干净，相关部位涂抹封存油，以免零件锈蚀。

6. If long-term sealing is required after shutdown, the cooling water and engine oil of the unit shall be drained, the surface of the unit shall be cleaned, and the sealing oil shall be applied to relevant parts to avoid corrosion of parts.

7、紧急停机。正常运行的燃气发电机组600kw，未按正常停机步骤停机都属于紧急停机。主要有两种情况：

7. Emergency stop. The 600 kW gas-fired generator set in normal operation, which is not shut down according to the normal shutdown steps, belongs to emergency shutdown. There are two main situations:

（1）发电机组因超速、油压低等故障原因，自行报警停机。

(1) The generator set will alarm and shut down automatically due to overspeed and low oil pressure.

（2）在使用过程中，遇到危及人身及设备稳定的紧急情况时，发电运行人员按下“紧急停车”按钮，人为机组停车。紧急停机的处理措施:切断电源，用盘车工具人力盘转曲轴，同时用手动机油泵泵油，带机组水温、油温降至60℃以下后，在进行检查处理。

(2) In case of emergency endangering personal and equipment stability during use, the power generation operator shall press the "emergency stop" button to stop the unit manually. Treatment measures for emergency shutdown: cut off the power supply, manually turn the crankshaft with turning tools, and pump oil with manual motor oil pump at the same time. After the water temperature and oil temperature of the unit drop below 60 ℃, carry out inspection and treatment.
