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、卸載：

1. Uninstall:

燃氣發(fā)電機組600kw停機前，要先卸去負荷。

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

2、怠速運行:

2. Idle operation:

額定轉速下運行幾分鐘，初步冷卻后，再將怠速/額定轉換開(kāi)關(guān)置于“怠速”位置，使機組怠速運行.使其水溫和油溫降下來(lái)。

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、切斷氣源：

3. Cut off the air supply:

當機組“水溫”、降低到60℃以下后，關(guān)閉手動(dòng)燃氣閥門(mén)。剩余的燃氣可使機組繼續運行1、2分鐘，燃氣耗盡后，機組將自動(dòng)停機。

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:

對于配置增壓器的機組，水溫、油溫降至60℃時(shí)不能接著(zhù)關(guān)氣、停機，應再空載運行5分鐘，使增壓器進(jìn)一步冷卻。否則會(huì )造成增壓器漏油。

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、停機后，將控制屏面板上的鑰匙關(guān)畢。

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

5、除發(fā)生飛車(chē)或工作場(chǎng)所出現易燃氣等意外事故，正常情況下嚴禁帶負荷停機。

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、若停車(chē)后需要長(cháng)期封存，應將機組的冷卻水和機油放凈，將機組表面處理干凈，相關(guān)部位涂抹封存油，以免零件銹蝕。

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、緊急停機。正常運行的燃氣發(fā)電機組600kw，未按正常停機步驟停機都屬于緊急停機。主要有兩種情況：

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）發(fā)電機組因超速、油壓低等故障原因，自行報警停機。

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

（2）在使用過(guò)程中，遇到危及人身及設備穩定的緊急情況時(shí)，發(fā)電運行人員按下“緊急停車(chē)”按鈕，人為機組停車(chē)。緊急停機的處理措施:切斷電源，用盤(pán)車(chē)工具人力盤(pán)轉曲軸，同時(shí)用手動(dòng)機油泵泵油，帶機組水溫、油溫降至60℃以下后，在進(jìn)行檢查處理。

(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.
