燃?xì)獍l(fā)電機(jī)組停機(jī)要做好哪些防護(hù)?
1、卸載:
1. Uninstall:
燃?xì)獍l(fā)電機(jī)組停機(jī)前,要先卸去負(fù)荷。
Before the gas generator unit is shut down, the load shall be removed first.
2、怠速運(yùn)行:
2. Idle running:
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(kāi)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(lái)。
Run for several minutes at rated speed, and after preliminary cooling, set the idle/rated transfer switch to the "idle" position to make the unit run at idle speed, and lower its water temperature 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(mén)。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 stop 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 ℃, the unit cannot be shut down and shut down again. It should be operated for another 5 minutes without load 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(chē)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. It is strictly prohibited to stop with load under normal conditions except for accidents such as speeding or flammable gas in the workplace.
6、若停車(chē)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 oil of the unit shall be drained, the surface of the unit shall be cleaned, and the relevant parts shall be coated with sealing oil to prevent parts from rusting.
7、緊急停機(jī)。正常運(yùn)行的燃?xì)獍l(fā)電機(jī)組,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 gas generator unit in normal operation that fails to 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 unit will automatically alarm and shut down due to overspeed, low oil pressure and other fault reasons.
(2)在使用過(guò)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(chē)”按鈕,人為機(jī)組停車(chē)。緊急停機(jī)的處理措施:切斷電源,用盤(pán)車(chē)工具人力盤(pán)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 the process of use, in case of emergency endangering the stability of personnel and equipment, the power generation operator presses the "emergency stop" button to manually stop the unit. Treatment measures for emergency shutdown: cut off the power supply, manually turn the crankshaft with the turning tool, and pump oil with the hand motor. After the water temperature and oil temperature of the unit drop below 60 ℃, check and handle
