The gas generator set is a new type of new energy generator that uses liquefied gas, natural gas and other combustible gases as the combustor and replaces gasoline and diesel as the engine power. For new users, what are the startup methods and steps for gas generator sets?

燃氣發(fā)電機組可以手動操作，合上預供油開關，啟動電動預供油泵（或扳動手搖機油泵）。待主油道壓力達到100kPa后，按下起動按鈕，機組起動后，立即釋放起動按鈕并斷開起動開關。機組每次起動時間為5s，若連續(xù)起動三次不成功，應檢查原因，排除故障后再起動。發(fā)動機運行后，可按下“翻頁”按鈕，通過液晶顯示屏檢查發(fā)動機運行中各項技術參數(shù)的變化。起動成功后應怠速暖機，當機油溫、水溫達到40℃以上，方可加速、加載。

The gas generator set can be operated manually. Close the pre oil supply switch and start the electric pre oil supply pump (or pull the hand oil pump). When the pressure of the main oil passage reaches 100KPA, press the start button. After the unit starts, release the start button and disconnect the start switch immediately. The unit shall be started for 5S each time. If the unit fails to be started for three consecutive times, the cause shall be checked and the unit shall be started after troubleshooting. After the engine is running, press the "page turning" button to check the changes of various technical parameters during engine operation through the LCD. After successful startup, the engine shall be warmed up at idle speed. When the engine oil temperature and water temperature reach above 40 ℃, the engine can be accelerated and loaded.

按動或調(diào)節(jié)控制屏上加減速旋鈕調(diào)整機組的頻率，使之略高于額定頻率。調(diào)整控制屏上的電壓調(diào)節(jié)器的微調(diào)旋鈕，使交流電壓表在400V位置，合上主開關，機組便向負載供電。機組帶載運行后，若電壓、頻率偏離了額定值，分別調(diào)節(jié)轉(zhuǎn)速旋鈕和電壓整定電位器，使電壓頻率達到額定值。

Press or adjust the acceleration and deceleration knob on the control panel to adjust the frequency of the unit to slightly higher than the rated frequency. Adjust the fine-tuning knob of the voltage regulator on the control panel so that the AC voltmeter is at the 400V position, close the main switch, and the unit will supply power to the load. After the unit operates under load, if the voltage and frequency deviate from the rated value, adjust the speed knob and the voltage setting potentiometer respectively to make the voltage and frequency reach the rated value.

燃氣發(fā)電機組還可以自動操作，對于應急自動燃氣發(fā)電機組來說，發(fā)電機組應該一直處于準啟動狀態(tài)（定期自動預潤滑、保持油溫水溫），在接到自動控制系統(tǒng)的啟動命令后（失去市電、總體功率不足等），機組會自動啟動，并且在達到額定狀態(tài)后自動合閘帶載。

The gas-fired generator set can also be operated automatically. For the emergency automatic gas-fired generator set, the generator set should always be in the quasi start state (regular automatic pre lubrication, maintaining oil and water temperature). After receiving the start command from the automatic control system (loss of mains power, insufficient overall power rate, etc.), the unit will start automatically, and will automatically switch on with load after reaching the rated state.

燃氣發(fā)電機組的停機和啟動一樣可以在機旁、控制屏處操作。發(fā)動機的停機操作一般在主開關已經(jīng)分閘后進行。無論在機旁、監(jiān)控室還是自動進行操作，基本的過程都是一樣的。正常停機應逐步卸去負載并主開關分閘后，將轉(zhuǎn)速選擇開關置“怠速”位，天然氣發(fā)動機機轉(zhuǎn)速至1500r/min。按照天然氣發(fā)動機使用維護說明書的要求對機組進行冷機后，將“停機”旋鈕旋至停機位置，使發(fā)動機停止工作。停機后將電氣開關全部置停機位置上，各調(diào)節(jié)旋鈕亦復原到停機的相應位置，以便下次起動。

The shutdown and startup of the gas generator set can be operated at the machine side and the control panel. The engine shutdown operation is generally carried out after the main switch has been opened. The basic process is the same whether it is operated at the machine side, in the monitoring room or automatically. After the normal shutdown, the load shall be gradually removed and the main switch is opened, the speed selection switch shall be set to the "idle" position, and the natural gas engine speed shall be 1500r/min. After cooling the unit in accordance with the requirements of the operation and maintenance manual of natural gas engine, turn the "stop" knob to the stop position to stop the engine. After the shutdown, set all the electrical switches to the shutdown position, and return all the adjustment knobs to the corresponding shutdown position for the next start.

由此看來，燃氣發(fā)電機組的開機操作可以在機旁進行，也可以在控制屏端進行。目前啟動機組使用多是自動啟動，機組的智能化的提高使機組自動啟動比手動啟動的效率更高。

From this point of view, the start-up operation of the gas generator set can be carried out at the machine side or at the control panel side. At present, most of the start-up units are automatically started. The improvement of the intelligence of the unit makes the efficiency of the automatic start-up of the unit higher than that of the manual start-up.
