　　。2、通入燃氣

　　2. Introduce gas

　　（1）打開手動燃氣閥門。

　　(1) Open the manual gas valve.

　　（2）手動將電動蝶閥撥至“開”位置，使燃氣進入機組。

　　(2) Manually turn the electric butterfly valve to the "on" position to allow gas to enter the unit.

　　3、機組啟動

　　3. Unit startup

　?。?）機組長期停放，第一次啟動前應 排空。方法為：關閉燃氣總閥門，切斷機組燃氣供給，斷開磁電機與點火線圈連線，預供油后，使啟動馬達帶動發(fā)動機空轉、將氣缸內的余氣排空。排空時應注意不要燒壞啟動馬達。

　　(1) The unit should be emptied before the first start-up if it is parked for a long time. The method is to close the gas main valve, cut off the gas supply to the unit, disconnect the connection between the magnetic motor and the ignition coil, pre supply oil, and let the starter motor drive the engine to idle and exhaust the remaining gas in the cylinder. Be careful not to burn out the starter motor when emptying.

　?。?）給電動預供油泵通電， 手搖機油泵和電動預供油泵配合使用，當機油壓力表指示為以上時，停止供油。

　　(2) Power on the electric pre supply oil pump, and use the hand cranked oil pump in conjunction with the electric pre supply oil pump. When the oil pressure gauge indicates above, stop supplying oil.

　?。?） 給啟動馬達通電，啟動發(fā)動機。啟動馬達連續(xù)運行不得超過5秒。若一次啟動不成功，則間隔至少2分鐘后方可再次啟動，并于再次啟動前將發(fā)動機氣缸內剩余氣體排空；若機組連續(xù)三次未能啟動，應立即停止，查明原因并排除后方可再次啟動。 如果連續(xù)啟動次數過多，馬達熱量無法散失，會燒壞啟動馬達。

　　(3) Power on the starter motor and start the engine. The starting motor should not run continuously for more than 5 seconds. If the first start is unsuccessful, wait for at least 2 minutes before restarting, and exhaust the remaining gas in the engine cylinder before restarting; If the unit fails to start for three consecutive times, it should be stopped immediately, the cause should be identified and eliminated before restarting. If the number of consecutive starts is too many, the heat of the motor cannot be dissipated, which will burn out the starting motor.

　　4、暖機運行

　　4. Warm up operation

　?。?）查看主油道、增壓器的機油壓力數值，濾前與濾后壓力差，如不正常應立即查找原因。

　　(1) Check the oil pressure values of the main oil passage and turbocharger, as well as the pressure difference between the pre filter and post filter. If it is abnormal, immediately investigate the cause.

　?。?）打開氣缸蓋上罩殼，觀察搖臂及橫橋各點、面摩擦副回油狀況，有回油流出是正常的，回油微量或沒有，說明外潤滑管路或搖臂、橫橋油道阻塞，應松開外潤滑管查找原因或疏通、更換橫橋、搖臂。如果大搖臂銅套兩端回油量非常大，說明銅套與搖臂軸間隙過大，應及時更換銅套。

　　(2) Open the cylinder head cover and observe the return oil condition of the rocker arm and cross bridge friction pair at each point and surface. It is normal for oil to flow out, but if there is little or no return oil, it indicates that the external lubrication pipeline or rocker arm and cross bridge oil passage is blocked. The external lubrication pipeline should be loosened to find the cause or to clear or replace the cross bridge and rocker arm. If the oil return at both ends of the large rocker arm copper sleeve is very large, it indicates that the clearance between the copper sleeve and the rocker arm shaft is too large, and the copper sleeve should be replaced in a timely manner.

　　（3）旋開水泵放水閥少許，若有強勁水柱沖出，則表明供水正常。新機或拆檢過冷卻管系的機組，應打開缸蓋高溫回水管線上的放氣螺塞，檢查兩排氣缸供水是否正常。

　　(3) Loosen the drain valve of the water pump slightly. If there is a strong water column rushing out, it indicates that the water supply is normal. For new units or units that have undergone dismantling and inspection of the cooling pipe system, the vent plug on the high-temperature return water pipeline of the cylinder head should be opened to check whether the water supply to the two rows of cylinders is normal.

　?。?）檢查機組外觀狀況，不得有漏水、漏油、漏氣現象。所有零部件應固定牢固，不得有明顯的振動或松動現象。

　　(4) Check the appearance of the unit for any water, oil, or gas leaks. All components should be firmly fixed without obvious vibration or looseness.

　?。?）觀察發(fā)動機排氣煙色是否正常，呼吸器有無異常煙氣，監(jiān)聽機組有無異常聲響（敲擊聲、放炮聲、吹噓聲等）。

　　(5) Observe whether the exhaust smoke color of the engine is normal, whether there is abnormal smoke in the respirator, and monitor whether there is any abnormal sound from the unit (knocking sound, blasting sound, bragging sound, etc.).

　?。?）嗅發(fā)動機是否有焦味、燃氣味。

　　(6) Smell the engine for any burnt or gas smell.

　?。?）用手背感覺各氣缸蓋升溫速度是否平衡、各冷卻管線前后溫度是否正常。正常情況下，各冷卻管線前后溫度應一致，各缸升溫速度較均勻一致。如某冷卻管線前后溫度不一致，說明管線內產生氣阻；如有個別缸升溫較快且在正常工作時缸溫也偏高，說明缸蓋內水腔狹窄，冷卻水流量受到限制，不能及時把熱量傳送出去。（8）充分暖機（一般水溫、油溫20℃以上）后，將控制屏上 “ 怠速/額定 ” 轉換開關置于 “ 額定 ” 位置，機組將提速、在額定轉速下運行。待水溫、油溫均上升到40℃以上，再觀察機組各儀表指示是否正常。若機組各儀表指示正常，則可并網發(fā)電。

　　(7) Use the back of your hand to feel whether the heating speed of each cylinder head is balanced and whether the temperature before and after each cooling pipeline is normal. Under normal circumstances, the temperature before and after each cooling pipeline should be consistent, and the heating rate of each cylinder should be relatively uniform and consistent. If the temperature before and after a certain cooling pipeline is inconsistent, it indicates that there is air resistance inside the pipeline; If a few cylinders heat up quickly and the cylinder temperature is also high during normal operation, it indicates that the water chamber in the cylinder head is narrow, the cooling water flow is limited, and the heat cannot be transferred out in a timely manner. (8) After fully warming up (generally with water temperature and oil temperature above 20 ℃), place the "idle/rated" switch on the control screen in the "rated" position, and the unit will accelerate and operate at the rated speed. Wait for the water and oil temperatures to rise above 40 ℃, and then observe whether the instrument readings of the unit are normal. If all instruments of the unit indicate normally, it can be connected to the grid for power generation.

　　5、并網

　　5. Grid connection

　?。?）預調整 “ 轉速微調 ” 旋紐，將發(fā)電機組的頻率調整至50Hz。

　　(1) Pre adjust the "speed fine-tuning" knob to adjust the frequency of the generator set to 50Hz.

　?。?）預調整 “ 整定電壓 ” 旋紐，將發(fā)電機組的電壓調整至與電網大致相同（約400V ） 。

　　(2) Pre adjust the "set voltage" knob to adjust the voltage of the generator set to approximately the same as the grid (about 400V).

　?。?）按下 “ 儲能 ” 按鈕，給（主斷路器）儲能，此時， “ 儲能 ” 指示燈亮。

　　(3) Press the "Energy Storage" button to store energy for the main circuit breaker, and the "Energy Storage" indicator light will turn on.

　?。?）并網或并車后立即將 “ 同步裝置 ” 開關斷開，以免燒壞同期表。

　　(4) Immediately disconnect the "synchronization device" switch after grid connection or parallel operation to avoid burning out the synchronization meter.

　　6、 正常工作運行

　　6. Normal operation

　　（1）將機組調整到正常功率后，運行人員可按照電站規(guī)定，每半小時在機房作一次巡回檢查。

　　(1) After adjusting the unit to normal power, the operating personnel can conduct a patrol inspection in the machine room every half an hour according to the regulations of the power station.

　?。?）觀察燃氣管系、潤滑管系、冷卻水管系、進排氣管系是否有泄露現象，有問題應及時排除。

　　(2) Observe whether there is any leakage in the gas pipeline system, lubrication pipeline system, cooling water pipeline system, and intake and exhaust pipeline system. If there is a problem, it should be promptly eliminated.

　?。?）觀察呼吸器是否有煙霧排出。如有煙霧，首先應判明是水蒸氣、油蒸汽還是燃燒的廢氣。如果是水蒸氣，且越來越大，說明有冷卻水滲漏到油底殼；如果是燃燒廢氣且煙霧突然增大，應立即停機檢查離心濾清器是否有金屬末（觀察離心濾轉子殼內側污垢時不要用手去摸，應在光線較好地方觀察，金屬末反光易發(fā)現）。

　　(3) Observe whether the respirator emits smoke. If there is smoke, the first thing to determine is whether it is water vapor, oil vapor, or combustion exhaust gas. If it is water vapor and it is getting larger, it indicates that there is cooling water leaking into the oil pan; If it is a combustion exhaust gas and the smoke suddenly increases, the centrifugal filter should be stopped immediately to check for any metal particles (do not touch the dirt on the inside of the centrifugal filter rotor housing with your hands, but observe in a well lit place, as the reflection of metal particles is easy to detect).

　　（4）觀察運動部件動作是否正常，監(jiān)聽機組運行聲音是否正常。

　　(4) Observe whether the movement of moving parts is normal, and monitor whether the sound of the unit's operation is normal.

　?。?）檢查機油油面的高度、機油粘度是否正常。

　　(5) Check if the oil level and viscosity of the engine oil are normal.

　?。?） 注意觀察發(fā)動機各缸缸溫、排溫（可利用手持紅外測溫儀），確保各缸工作正常。 缸溫、排溫過高時應及時檢查空氣濾芯是否阻塞，如阻塞會使進氣產生負壓造成增壓器漏油，或者 調整發(fā)動機的空燃比或點火提前角。

　　(6) Pay attention to observing the cylinder temperature and exhaust temperature of each engine cylinder (using a handheld infrared thermometer) to ensure that each cylinder is working properly. When the cylinder temperature and exhaust temperature are too high, it is necessary to check whether the air filter is blocked in a timely manner. If it is blocked, it will cause negative pressure in the intake and cause oil leakage in the turbocharger, or adjust the air-fuel ratio or ignition advance angle of the engine.

　　（7）每1-2小時對機組各參數作一次正式書面記錄。如數據異常，應查找原因并排除。應特別密切關注機組的水溫、油溫、油壓、缸溫、排溫。（滿載時理想的水溫、油溫是70-80℃，機油壓力是，加載后油壓下降左右是正常的）

　　(7) Make a formal written record of each parameter of the unit every 1-2 hours. If the data is abnormal, the cause should be identified and eliminated. Special attention should be paid to the water temperature, oil temperature, oil pressure, cylinder temperature, and exhaust temperature of the unit. The ideal water temperature and oil temperature at full load are 70-80 ℃, and the oil pressure is. It is normal for the oil pressure to decrease by about after loading

　　7、停車

　　7. Parking

　?。?）準備停機前應對機組進行一次全面檢查，判明工作狀況，以便保養(yǎng)、修理。

　　(1) Before shutting down, a comprehensive inspection of the unit should be conducted to determine its working condition for maintenance and repair.

　?。?）正常停機應按以下步驟進行：①卸載機組停機前，要先卸去負荷。緩慢逆時針調節(jié) “ 轉速微調 ” 旋鈕，逐漸卸下負載。注意：在減小負載的同時需要通過 TEM 系統(tǒng)或集中控制箱 逐漸關閉電控混合器的燃氣蝶門、減少燃氣量、降低機組轉速，否則會放炮、超速（飛車）。②分閘或解列當機組功率降至40kW以下時，迅速按下 “ 分閘 ” 按鈕。③怠速運行機組在額定轉速下運行幾分鐘、初步冷卻后，再將 “ 怠速/額定 ” 轉換開關置于 “ 怠速 ” 位置，使機組怠速運行。注意 ：分閘后，不得立即將 “ 怠速/額定 ” 轉換開關置于 “ 怠速 ” 位置，以免縮短機組使用壽命。④切斷氣源當機組 “ 水溫 ” 、 “ 油溫 ” 降低到60℃以下后，關閉手動燃氣閥門。管道內剩余的燃氣可使機組繼續(xù)運行1、2分鐘，燃氣耗盡后，機組將自動停機。注意 ：對于配置增壓器的機組，水溫、油溫降至60℃時不能立即關氣、停機，應再空載運行5分鐘，使增壓器進一步冷卻，否則增壓器摩擦副會結膠、結碳，密封環(huán)降低彈性，造成增壓器漏油。⑤將控制屏面板上的 “ 電磁閥電源 ” 開關置于 “ 關 ” 的位置，關閉電磁閥。⑥ 將“功率因數自動/手動”開關置于“手動”位置，將“直流電源”、“電調電源”等電位器、旋扭恢復到停機位置，以便下次啟動。

　　(2) Normal shutdown should be carried out according to the following steps: ① Before shutting down the unloading unit, the load should be unloaded first. Slowly adjust the "speed fine adjustment" knob counterclockwise and gradually remove the load. Attention: While reducing the load, it is necessary to gradually close the gas butterfly valve of the electric control mixer, reduce the gas volume, and lower the unit speed through the TEM system or centralized control box, otherwise it will cause explosion and overspeed (runaway). ② When the power of the unit drops below 40kW, quickly press the "trip" button. ③ After running the unit at rated speed for a few minutes and cooling down, place the "idle/rated" switch in the "idle" position to allow the unit to run at idle speed. Attention: After disconnecting, do not immediately place the "idle/rated" switch in the "idle" position to avoid shortening the service life of the unit. ④ Cut off the gas source. When the "water temperature" and "oil temperature" of the unit drop below 60 ℃, close the manual gas valve. The remaining gas in the pipeline can keep the unit running for 1-2 minutes. After the gas is exhausted, the unit will automatically shut down. Attention: For units equipped with a turbocharger, when the water temperature and oil temperature drop to 60 ℃, the air cannot be immediately turned off or stopped. It should be run without load for another 5 minutes to further cool the turbocharger. Otherwise, the friction pair of the turbocharger will form glue and carbon, and the sealing ring will reduce elasticity, causing oil leakage from the turbocharger. ⑤ Set the "Electromagnetic Valve Power" switch on the control screen panel to the "OFF" position and turn off the electromagnetic valve. ⑥ Place the "Power Factor Auto/Manual" switch in the "Manual" position, and restore potentiometers and knobs such as "DC Power" and "Electric Adjustable Power" to the shutdown position for the next start.

　?。?） 停機后排除運行中發(fā)現的故障，并按規(guī)定對機組進行保養(yǎng)。

　　(3) After shutdown, troubleshoot any faults found during operation and perform maintenance on the unit according to regulations.

　?。?） 若需要更換機油時，停車后待油中雜質尚未沉淀時，將機油放凈。

　　(4) If it is necessary to change the engine oil, after parking and waiting for impurities in the oil to settle, drain the engine oil completely.

　　（5） 若停機后機組長期封存，應按封車規(guī)定作封車處理。

　　(5) If the unit is sealed for a long time after shutdown, it should be sealed according to the sealing regulations.

　?。?） 整理并填寫運行記錄和交接班記錄，清理現場，做好交接班準備工作。

　　(6) Organize and fill in operation records and shift handover records, clean up the site, and prepare for shift handover.

　　。2、通入燃氣

　　2. Introduce gas

　?。?）打開手動燃氣閥門。

　　(1) Open the manual gas valve.

　　（2）手動將電動蝶閥撥至“開”位置，使燃氣進入機組。

　　(2) Manually turn the electric butterfly valve to the "on" position to allow gas to enter the unit.

　　3、機組啟動

　　3. Unit startup

　?。?）機組長期停放，第一次啟動前應 排空。方法為：關閉燃氣總閥門，切斷機組燃氣供給，斷開磁電機與點火線圈連線，預供油后，使啟動馬達帶動發(fā)動機空轉、將氣缸內的余氣排空。排空時應注意不要燒壞啟動馬達。

　　(1) The unit should be emptied before the first start-up if it is parked for a long time. The method is to close the gas main valve, cut off the gas supply to the unit, disconnect the connection between the magnetic motor and the ignition coil, pre supply oil, and let the starter motor drive the engine to idle and exhaust the remaining gas in the cylinder. Be careful not to burn out the starter motor when emptying.

　?。?）給電動預供油泵通電， 手搖機油泵和電動預供油泵配合使用，當機油壓力表指示為以上時，停止供油。

　　(2) Power on the electric pre supply oil pump, and use the hand cranked oil pump in conjunction with the electric pre supply oil pump. When the oil pressure gauge indicates above, stop supplying oil.

　?。?） 給啟動馬達通電，啟動發(fā)動機。啟動馬達連續(xù)運行不得超過5秒。若一次啟動不成功，則間隔至少2分鐘后方可再次啟動，并于再次啟動前將發(fā)動機氣缸內剩余氣體排空；若機組連續(xù)三次未能啟動，應立即停止，查明原因并排除后方可再次啟動。 如果連續(xù)啟動次數過多，馬達熱量無法散失，會燒壞啟動馬達。

　　(3) Power on the starter motor and start the engine. The starting motor should not run continuously for more than 5 seconds. If the first start is unsuccessful, wait for at least 2 minutes before restarting, and exhaust the remaining gas in the engine cylinder before restarting; If the unit fails to start for three consecutive times, it should be stopped immediately, the cause should be identified and eliminated before restarting. If the number of consecutive starts is too many, the heat of the motor cannot be dissipated, which will burn out the starting motor.

　　4、暖機運行

　　4. Warm up operation

　?。?）查看主油道、增壓器的機油壓力數值，濾前與濾后壓力差，如不正常應立即查找原因。

　　(1) Check the oil pressure values of the main oil passage and turbocharger, as well as the pressure difference between the pre filter and post filter. If it is abnormal, immediately investigate the cause.

　?。?）打開氣缸蓋上罩殼，觀察搖臂及橫橋各點、面摩擦副回油狀況，有回油流出是正常的，回油微量或沒有，說明外潤滑管路或搖臂、橫橋油道阻塞，應松開外潤滑管查找原因或疏通、更換橫橋、搖臂。如果大搖臂銅套兩端回油量非常大，說明銅套與搖臂軸間隙過大，應及時更換銅套。

　　(2) Open the cylinder head cover and observe the return oil condition of the rocker arm and cross bridge friction pair at each point and surface. It is normal for oil to flow out, but if there is little or no return oil, it indicates that the external lubrication pipeline or rocker arm and cross bridge oil passage is blocked. The external lubrication pipeline should be loosened to find the cause or to clear or replace the cross bridge and rocker arm. If the oil return at both ends of the large rocker arm copper sleeve is very large, it indicates that the clearance between the copper sleeve and the rocker arm shaft is too large, and the copper sleeve should be replaced in a timely manner.

　?。?）旋開水泵放水閥少許，若有強勁水柱沖出，則表明供水正常。新機或拆檢過冷卻管系的機組，應打開缸蓋高溫回水管線上的放氣螺塞，檢查兩排氣缸供水是否正常。

　　(3) Loosen the drain valve of the water pump slightly. If there is a strong water column rushing out, it indicates that the water supply is normal. For new units or units that have undergone dismantling and inspection of the cooling pipe system, the vent plug on the high-temperature return water pipeline of the cylinder head should be opened to check whether the water supply to the two rows of cylinders is normal.

　?。?）檢查機組外觀狀況，不得有漏水、漏油、漏氣現象。所有零部件應固定牢固，不得有明顯的振動或松動現象。

　　(4) Check the appearance of the unit for any water, oil, or gas leaks. All components should be firmly fixed without obvious vibration or looseness.

　?。?）觀察發(fā)動機排氣煙色是否正常，呼吸器有無異常煙氣，監(jiān)聽機組有無異常聲響（敲擊聲、放炮聲、吹噓聲等）。

　　(5) Observe whether the exhaust smoke color of the engine is normal, whether there is abnormal smoke in the respirator, and monitor whether there is any abnormal sound from the unit (knocking sound, blasting sound, bragging sound, etc.).

　?。?）嗅發(fā)動機是否有焦味、燃氣味。

　　(6) Smell the engine for any burnt or gas smell.

　?。?）用手背感覺各氣缸蓋升溫速度是否平衡、各冷卻管線前后溫度是否正常。正常情況下，各冷卻管線前后溫度應一致，各缸升溫速度較均勻一致。如某冷卻管線前后溫度不一致，說明管線內產生氣阻；如有個別缸升溫較快且在正常工作時缸溫也偏高，說明缸蓋內水腔狹窄，冷卻水流量受到限制，不能及時把熱量傳送出去。（8）充分暖機（一般水溫、油溫20℃以上）后，將控制屏上 “ 怠速/額定 ” 轉換開關置于 “ 額定 ” 位置，機組將提速、在額定轉速下運行。待水溫、油溫均上升到40℃以上，再觀察機組各儀表指示是否正常。若機組各儀表指示正常，則可并網發(fā)電。

　　(7) Use the back of your hand to feel whether the heating speed of each cylinder head is balanced and whether the temperature before and after each cooling pipeline is normal. Under normal circumstances, the temperature before and after each cooling pipeline should be consistent, and the heating rate of each cylinder should be relatively uniform and consistent. If the temperature before and after a certain cooling pipeline is inconsistent, it indicates that there is air resistance inside the pipeline; If a few cylinders heat up quickly and the cylinder temperature is also high during normal operation, it indicates that the water chamber in the cylinder head is narrow, the cooling water flow is limited, and the heat cannot be transferred out in a timely manner. (8) After fully warming up (generally with water temperature and oil temperature above 20 ℃), place the "idle/rated" switch on the control screen in the "rated" position, and the unit will accelerate and operate at the rated speed. Wait for the water and oil temperatures to rise above 40 ℃, and then observe whether the instrument readings of the unit are normal. If all instruments of the unit indicate normally, it can be connected to the grid for power generation.

　　5、并網

　　5. Grid connection

　?。?）預調整 “ 轉速微調 ” 旋紐，將發(fā)電機組的頻率調整至50Hz。

　　(1) Pre adjust the "speed fine-tuning" knob to adjust the frequency of the generator set to 50Hz.

　?。?）預調整 “ 整定電壓 ” 旋紐，將發(fā)電機組的電壓調整至與電網大致相同（約400V ） 。

　　(2) Pre adjust the "set voltage" knob to adjust the voltage of the generator set to approximately the same as the grid (about 400V).

　?。?）按下 “ 儲能 ” 按鈕，給（主斷路器）儲能，此時， “ 儲能 ” 指示燈亮。

　　(3) Press the "Energy Storage" button to store energy for the main circuit breaker, and the "Energy Storage" indicator light will turn on.

　?。?）并網或并車后立即將 “ 同步裝置 ” 開關斷開，以免燒壞同期表。

　　(4) Immediately disconnect the "synchronization device" switch after grid connection or parallel operation to avoid burning out the synchronization meter.

　　6、 正常工作運行

　　6. Normal operation

　?。?）將機組調整到正常功率后，運行人員可按照電站規(guī)定，每半小時在機房作一次巡回檢查。

　　(1) After adjusting the unit to normal power, the operating personnel can conduct a patrol inspection in the machine room every half an hour according to the regulations of the power station.

　　（2）觀察燃氣管系、潤滑管系、冷卻水管系、進排氣管系是否有泄露現象，有問題應及時排除。

　　(2) Observe whether there is any leakage in the gas pipeline system, lubrication pipeline system, cooling water pipeline system, and intake and exhaust pipeline system. If there is a problem, it should be promptly eliminated.

　?。?）觀察呼吸器是否有煙霧排出。如有煙霧，首先應判明是水蒸氣、油蒸汽還是燃燒的廢氣。如果是水蒸氣，且越來越大，說明有冷卻水滲漏到油底殼；如果是燃燒廢氣且煙霧突然增大，應立即停機檢查離心濾清器是否有金屬末（觀察離心濾轉子殼內側污垢時不要用手去摸，應在光線較好地方觀察，金屬末反光易發(fā)現）。

　　(3) Observe whether the respirator emits smoke. If there is smoke, the first thing to determine is whether it is water vapor, oil vapor, or combustion exhaust gas. If it is water vapor and it is getting larger, it indicates that there is cooling water leaking into the oil pan; If it is a combustion exhaust gas and the smoke suddenly increases, the centrifugal filter should be stopped immediately to check for any metal particles (do not touch the dirt on the inside of the centrifugal filter rotor housing with your hands, but observe in a well lit place, as the reflection of metal particles is easy to detect).

　?。?）觀察運動部件動作是否正常，監(jiān)聽機組運行聲音是否正常。

　　(4) Observe whether the movement of moving parts is normal, and monitor whether the sound of the unit's operation is normal.

　?。?）檢查機油油面的高度、機油粘度是否正常。

　　(5) Check if the oil level and viscosity of the engine oil are normal.

　?。?） 注意觀察發(fā)動機各缸缸溫、排溫（可利用手持紅外測溫儀），確保各缸工作正常。 缸溫、排溫過高時應及時檢查空氣濾芯是否阻塞，如阻塞會使進氣產生負壓造成增壓器漏油，或者 調整發(fā)動機的空燃比或點火提前角。

　　(6) Pay attention to observing the cylinder temperature and exhaust temperature of each engine cylinder (using a handheld infrared thermometer) to ensure that each cylinder is working properly. When the cylinder temperature and exhaust temperature are too high, it is necessary to check whether the air filter is blocked in a timely manner. If it is blocked, it will cause negative pressure in the intake and cause oil leakage in the turbocharger, or adjust the air-fuel ratio or ignition advance angle of the engine.

　?。?）每1-2小時對機組各參數作一次正式書面記錄。如數據異常，應查找原因并排除。應特別密切關注機組的水溫、油溫、油壓、缸溫、排溫。（滿載時理想的水溫、油溫是70-80℃，機油壓力是，加載后油壓下降左右是正常的）

　　(7) Make a formal written record of each parameter of the unit every 1-2 hours. If the data is abnormal, the cause should be identified and eliminated. Special attention should be paid to the water temperature, oil temperature, oil pressure, cylinder temperature, and exhaust temperature of the unit. The ideal water temperature and oil temperature at full load are 70-80 ℃, and the oil pressure is. It is normal for the oil pressure to decrease by about after loading

　　7、停車

　　7. Parking

　?。?）準備停機前應對機組進行一次全面檢查，判明工作狀況，以便保養(yǎng)、修理。

　　(1) Before shutting down, a comprehensive inspection of the unit should be conducted to determine its working condition for maintenance and repair.

　?。?）正常停機應按以下步驟進行：①卸載機組停機前，要先卸去負荷。緩慢逆時針調節(jié) “ 轉速微調 ” 旋鈕，逐漸卸下負載。注意：在減小負載的同時需要通過 TEM 系統(tǒng)或集中控制箱 逐漸關閉電控混合器的燃氣蝶門、減少燃氣量、降低機組轉速，否則會放炮、超速（飛車）。②分閘或解列當機組功率降至40kW以下時，迅速按下 “ 分閘 ” 按鈕。③怠速運行機組在額定轉速下運行幾分鐘、初步冷卻后，再將 “ 怠速/額定 ” 轉換開關置于 “ 怠速 ” 位置，使機組怠速運行。注意 ：分閘后，不得立即將 “ 怠速/額定 ” 轉換開關置于 “ 怠速 ” 位置，以免縮短機組使用壽命。④切斷氣源當機組 “ 水溫 ” 、 “ 油溫 ” 降低到60℃以下后，關閉手動燃氣閥門。管道內剩余的燃氣可使機組繼續(xù)運行1、2分鐘，燃氣耗盡后，機組將自動停機。注意 ：對于配置增壓器的機組，水溫、油溫降至60℃時不能立即關氣、停機，應再空載運行5分鐘，使增壓器進一步冷卻，否則增壓器摩擦副會結膠、結碳，密封環(huán)降低彈性，造成增壓器漏油。⑤將控制屏面板上的 “ 電磁閥電源 ” 開關置于 “ 關 ” 的位置，關閉電磁閥。⑥ 將“功率因數自動/手動”開關置于“手動”位置，將“直流電源”、“電調電源”等電位器、旋扭恢復到停機位置，以便下次啟動。

　　(2) Normal shutdown should be carried out according to the following steps: ① Before shutting down the unloading unit, the load should be unloaded first. Slowly adjust the "speed fine adjustment" knob counterclockwise and gradually remove the load. Attention: While reducing the load, it is necessary to gradually close the gas butterfly valve of the electric control mixer, reduce the gas volume, and lower the unit speed through the TEM system or centralized control box, otherwise it will cause explosion and overspeed (runaway). ② When the power of the unit drops below 40kW, quickly press the "trip" button. ③ After running the unit at rated speed for a few minutes and cooling down, place the "idle/rated" switch in the "idle" position to allow the unit to run at idle speed. Attention: After disconnecting, do not immediately place the "idle/rated" switch in the "idle" position to avoid shortening the service life of the unit. ④ Cut off the gas source. When the "water temperature" and "oil temperature" of the unit drop below 60 ℃, close the manual gas valve. The remaining gas in the pipeline can keep the unit running for 1-2 minutes. After the gas is exhausted, the unit will automatically shut down. Attention: For units equipped with a turbocharger, when the water temperature and oil temperature drop to 60 ℃, the air cannot be immediately turned off or stopped. It should be run without load for another 5 minutes to further cool the turbocharger. Otherwise, the friction pair of the turbocharger will form glue and carbon, and the sealing ring will reduce elasticity, causing oil leakage from the turbocharger. ⑤ Set the "Electromagnetic Valve Power" switch on the control screen panel to the "OFF" position and turn off the electromagnetic valve. ⑥ Place the "Power Factor Auto/Manual" switch in the "Manual" position, and restore potentiometers and knobs such as "DC Power" and "Electric Adjustable Power" to the shutdown position for the next start.

　?。?） 停機后排除運行中發(fā)現的故障，并按規(guī)定對機組進行保養(yǎng)。

　　(3) After shutdown, troubleshoot any faults found during operation and perform maintenance on the unit according to regulations.

　?。?） 若需要更換機油時，停車后待油中雜質尚未沉淀時，將機油放凈。

　　(4) If it is necessary to change the engine oil, after parking and waiting for impurities in the oil to settle, drain the engine oil completely.

　?。?） 若停機后機組長期封存，應按封車規(guī)定作封車處理。

　　(5) If the unit is sealed for a long time after shutdown, it should be sealed according to the sealing regulations.

　?。?） 整理并填寫運行記錄和交接班記錄，清理現場，做好交接班準備工作。

　　(6) Organize and fill in operation records and shift handover records, clean up the site, and prepare for shift handover.
