柴油發(fā)電機組開機步驟如下:
1、擰松噴油泵上的放氣螺釘,用燃油手泵排除燃油系統(tǒng)內(nèi)的空氣,同時將調(diào)整控制手柄固定在適宜啟動轉(zhuǎn)速的油門位置。
2、按下啟動按鈕,使柴油機啟動,如10秒(最多15秒),柴油機仍不能著火啟動,則應待1分鐘后再作第二次啟動,若連續(xù)三次仍無法啟動則應檢查并找出故障原因。
3、柴油機啟動后,應密切注意機油壓力表讀數(shù)(正常運轉(zhuǎn)時為2.5—3.5kg/C㎡),如機油壓力表不指示,應立即停機檢查,并檢查電流表有無充電指示。
4、柴油發(fā)電機組啟動后,空載轉(zhuǎn)速逐漸增加到1000—1200r/min,(注意不得長時間低速運轉(zhuǎn)),進行柴油機的預熱過程后,再將轉(zhuǎn)速提高到額定轉(zhuǎn)速。待出水溫度達到55℃,機油溫度達到45℃時,才允許進入全負荷運轉(zhuǎn)。
5、當發(fā)電機組各儀表指示正常時,即可合上負荷開關向負載送電,隨著機組負荷的變化,若頻率和電壓不在規(guī)定范圍內(nèi),應及時調(diào)整頻率和電壓,使其保持額定值,嚴禁發(fā)電機組在低轉(zhuǎn)速情況下帶負荷,以免損壞設備。
6、機組投入正常運轉(zhuǎn)后,應隨時注意觀察水溫、油溫、油壓的變化以及功率表、頻率表、電流表、電壓表的讀數(shù),發(fā)現(xiàn)異常應及時處理。
The start-up steps of the diesel generator set are as follows:
1. Loosen the bleed screw on the fuel injection pump, use a fuel hand pump to remove air from the fuel system, and fix the adjustment control handle at the appropriate throttle position for starting speed.
2. Press the start button to start the diesel engine. If the engine still cannot ignite and start after 10 seconds (up to 15 seconds), wait for 1 minute before starting again. If it still cannot start for three consecutive times, check and identify the cause of the fault.
3. After starting the diesel engine, close attention should be paid to the reading on the oil pressure gauge (2.5-3.5 kg/C ㎡ during normal operation). If the oil pressure gauge does not indicate, the engine should be stopped immediately for inspection, and the ammeter should be checked for charging indication.
4. After the diesel generator set is started, the no-load speed gradually increases to 1000-1200r/min (note not to run at low speed for a long time), and after the preheating process of the diesel engine, the speed is increased to the rated speed. Only when the outlet water temperature reaches 55 ℃ and the engine oil temperature reaches 45 ℃, is it allowed to enter full load operation.
5. When the various instruments of the generator set indicate normally, the load switch can be closed to supply power to the load. As the load of the unit changes, if the frequency and voltage are not within the specified range, they should be adjusted in a timely manner to maintain the rated value. It is strictly prohibited for the generator set to carry the load at low speed to avoid damaging the equipment.
6. After the unit is put into normal operation, attention should be paid to the changes in water temperature, oil temperature, oil pressure, as well as the readings of the power meter, frequency meter, ammeter, and voltmeter at all times. Any abnormalities should be promptly dealt with.
