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?xì)獍l(fā)電機(jī)組600kw停機(jī)前，要先卸去負(fù)荷。

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

2、怠速運(yùn)行:

2. Idle operation:

額定轉(zhuǎn)速下運(yùn)行幾分鐘，初步冷卻后，再將怠速/額定轉(zhuǎn)換開關(guān)置于“怠速”位置，使機(jī)組怠速運(yùn)行.使其水溫和油溫降下來。

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(dāng)機(jī)組“水溫”、降低到60℃以下后，關(guān)閉手動(dòng)燃?xì)忾y門。剩余的燃?xì)饪墒箼C(jī)組繼續(xù)運(yùn)行1、2分鐘，燃?xì)夂谋M后，機(jī)組將自動(dòng)停機(jī)。

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(duì)于配置增壓器的機(jī)組，水溫、油溫降至60℃時(shí)不能接著關(guān)氣、停機(jī)，應(yīng)再空載運(yùn)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(jī)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)生飛車或工作場(chǎng)所出現(xiàn)易燃?xì)獾纫馔馐鹿剩Ｇ闆r下嚴(yán)禁帶負(fù)荷停機(jī)。

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、若停車后需要長(zhǎng)期封存，應(yīng)將機(jī)組的冷卻水和機(jī)油放凈，將機(jī)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(jī)。正常運(yùn)行的燃?xì)獍l(fā)電機(jī)組600kw，未按正常停機(jī)步驟停機(jī)都屬于緊急停機(jī)。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(jī)組因超速、油壓低等故障原因，自行報(bào)警停機(jī)。

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

（2）在使用過程中，遇到危及人身及設(shè)備穩(wěn)定的緊急情況時(shí)，發(fā)電運(yùn)行人員按下“緊急停車”按鈕，人為機(jī)組停車。緊急停機(jī)的處理措施:切斷電源，用盤車工具人力盤轉(zhuǎn)曲軸，同時(shí)用手動(dòng)機(jī)油泵泵油，帶機(jī)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.
