燃氣發(fā)電機組啟動前的準備工作至關重要，它關系到機組的順利啟動以及后續(xù)的穩(wěn)定運行。以下是一份詳細的啟動前準備指南：

　　The preparation work before starting the gas generator set is crucial, as it is related to the smooth start-up and subsequent stable operation of the unit. Here is a detailed pre launch preparation guide:

　　一、外觀與連接檢查

　　1、 Appearance and connection inspection

　　零部件完整性：確保發(fā)電機組所有零部件齊全完整，無缺失或損壞。

　　Component integrity: Ensure that all components of the generator set are complete and undamaged.

　　管路連接：檢查各管路連接是否正確、密封有效，特別是燃氣管道、冷卻水管路、機油管路等，確保無泄漏。

　　Pipeline connection: Check whether each pipeline connection is correct and sealed effectively, especially the gas pipeline, cooling water pipeline, oil pipeline, etc., to ensure no leakage.

　　底盤與部件聯(lián)結：檢查底盤及各部件聯(lián)結是否牢固，無松動現(xiàn)象。

　　Chassis and component connection: Check whether the chassis and various components are firmly connected without any looseness.

　　二、進氣系統(tǒng)檢查

　　2、 Air intake system inspection

　　燃氣管道檢查：檢查發(fā)電機組進氣口前的燃氣管道、燃氣處理設備、安全裝置聯(lián)接是否可靠，無泄漏。

　　Gas pipeline inspection: Check whether the gas pipeline, gas treatment equipment, and safety device connections in front of the generator set inlet are reliable and leak free.

　　燃氣閥門：在準備工作完成前，不要開啟燃氣閥門，以防燃氣散發(fā)引發(fā)報警。但在檢查階段，需要打開燃氣閥門（注意控制時間，避免長時間開啟），用肥皂水等方法檢查機組燃氣管路應無漏氣。

　　Gas valve: Do not open the gas valve until the preparation work is completed to prevent gas emission from triggering an alarm. But during the inspection phase, it is necessary to open the gas valve (pay attention to controlling the time and avoid prolonged opening), and use soap water and other methods to check that there is no air leakage in the gas pipeline of the unit.

　　三、潤滑系統(tǒng)檢查

　　3、 Lubrication system inspection

　　機油油位：檢查機油油位是否在規(guī)定范圍內(nèi)，接近油標尺的上刻度線位置為宜。

　　Oil level: Check if the oil level is within the specified range, preferably close to the upper mark of the dipstick.

　　機油質(zhì)量：檢查機油質(zhì)量是否符合要求，如有異常（如變質(zhì)、污染等），應及時更換。

　　Oil quality: Check whether the oil quality meets the requirements. If there are any abnormalities (such as deterioration, contamination, etc.), it should be replaced in a timely manner.

　　機油濾清器：檢查機油濾清器、機油泵等部件是否工作正常，確保機油能夠順暢地輸送到各個潤滑點。

　　Oil filter: Check whether the oil filter, oil pump and other components are working properly to ensure that the oil can be smoothly delivered to various lubrication points.

　　四、冷卻系統(tǒng)檢查

　　4、 Cooling system inspection

　　內(nèi)循環(huán)冷卻水：檢查機組內(nèi)循環(huán)冷卻水是否清潔，并符合規(guī)定要求。向高架水箱內(nèi)加注清潔的軟化水，水面高度到合適位置。如需預熱，當外界環(huán)境溫度低于5攝氏度時，應將冷卻液預熱到20攝氏度以上。

　　Internal circulating cooling water: Check whether the internal circulating cooling water of the unit is clean and meets the specified requirements. Fill the elevated water tank with clean softened water until the water level reaches the appropriate position. If preheating is required, when the external ambient temperature is below 5 degrees Celsius, the coolant should be preheated to above 20 degrees Celsius.

　　外循環(huán)冷卻水池：檢查機組外循環(huán)冷卻水池水位、水質(zhì)。

　　External circulation cooling water tank: Check the water level and quality of the unit's external circulation cooling water tank.

　　五、電氣系統(tǒng)檢查

　　5、 Electrical system inspection

　　連接導線：檢查各處連接導線是否牢固，無破損、老化或接觸不良現(xiàn)象。

　　Connecting wires: Check whether the connecting wires at all locations are firm, without damage, aging, or poor contact.

　　絕緣電阻：測量電氣回路的對地以及回路之間的絕緣電阻是否達到規(guī)定值。對于初次投入運行的機組，應使用500V兆歐表測量各電器回路對地及回路之間的冷態(tài)絕緣電阻，測量結果不低于2MΩ。

　　Insulation resistance: Measure whether the insulation resistance of an electrical circuit to ground and between circuits reaches the specified value. For units that are put into operation for the first time, a 500V megohmmeter should be used to measure the cold insulation resistance of each electrical circuit to ground and between circuits, and the measurement result should not be less than 2M Ω.

　　蓄電池接線：檢查蓄電池的接線是否牢固可靠，接線時應先將蓄電池的正極接入啟動繼電器下接線柱上，然后再將負極接入機器底盤上，并將接線處的漆銹清除干凈。

　　Battery wiring: Check if the battery wiring is secure and reliable. When wiring, first connect the positive terminal of the battery to the lower terminal of the starting relay, then connect the negative terminal to the machine chassis, and clean the paint and rust at the wiring.

　　相序檢查：機組并網(wǎng)（并車）運行前進行相序檢查，確保發(fā)電機組的相序與電網(wǎng)的相序相同，或機組與機組間相序一致。

　　Phase sequence check: Before the unit is connected to the grid (parallel operation), a phase sequence check should be conducted to ensure that the phase sequence of the generator set is the same as that of the power grid, or that the phase sequence between units is consistent.

　　報警系統(tǒng)：檢查控制屏上的報警指示及聲響動作是否正常。合上蓄電池開關，按動試報警按鈕，各指示燈應同時閃爍，電鈴或電喇叭應發(fā)出報警聲響；按動消音按鈕，聲響應終止；按動報警解除按鈕，各指示燈應熄滅。

　　Alarm system: Check whether the alarm indication and sound action on the control screen are normal. Close the battery switch and press the alarm button. All indicator lights should flash simultaneously, and the electric bell or horn should sound an alarm; Press the mute button, and the sound should stop; Press the alarm release button, and all indicator lights should turn off.

　　六、其他檢查

　　6、 Other inspections

　　水霧輸送系統(tǒng)（如適用）：檢查水霧輸送系統(tǒng)狀態(tài)是否正常。

　　Water mist conveying system (if applicable): Check if the status of the water mist conveying system is normal.

　　氣源壓力表：檢查氣源壓力表指數(shù)是否正常。

　　Gas source pressure gauge: Check if the index of the gas source pressure gauge is normal.

　　操作空間：確保發(fā)電機周圍有足夠的操作空間，以便于日常維護與緊急停機操作。

　　Operating space: Ensure sufficient operating space around the generator for daily maintenance and emergency shutdown operations.

　　場地安全：檢查發(fā)電機放置的場地是否平整、無易燃易爆物品，通風良好，遠離火源和熱源。

　　Site safety: Check if the site where the generator is placed is flat, free of flammable and explosive materials, well ventilated, and away from fire and heat sources.

　　七、啟動前準備確認

　　7、 Preparation confirmation before startup

　　確認準備工作就緒：在確認所有準備工作就緒后，方可按照操作規(guī)程啟動發(fā)電機。

　　Confirm readiness of preparations: The generator can only be started according to the operating procedures after confirming that all preparations are ready.

　　熟悉操作規(guī)程：操作人員應熟悉燃氣發(fā)電機組的操作規(guī)程和緊急停機流程。

　　Familiar with operating procedures: Operators should be familiar with the operating procedures and emergency shutdown procedures of gas generator sets.

　　綜上所述，燃氣發(fā)電機組啟動前的準備工作涉及多個方面，從外觀檢查、進氣系統(tǒng)、潤滑系統(tǒng)、冷卻系統(tǒng)、電氣系統(tǒng)到其他相關檢查等，每一步都至關重要。只有確保所有準備工作都已完成并符合要求，才能確保機組的順利啟動和穩(wěn)定運行。

　　In summary, the preparation work before starting a gas generator unit involves multiple aspects, from visual inspection, intake system, lubrication system, cooling system, electrical system to other related inspections, each step is crucial. Only by ensuring that all preparatory work has been completed and meets the requirements can the smooth start-up and stable operation of the unit be guaranteed.
