The gas generator set can be manually operated by closing the pre oil supply switch and starting the electric pre oil pump (or pulling the hand operated oil pump). After the main oil duct pressure reaches 100kPa, press the start button. After the unit starts, immediately release the start button and disconnect the start switch. The starting time of the unit is 5 seconds each time. If the unit fails to start three consecutive times, the cause should be checked and the fault should be eliminated before starting. After the engine is running, you can press the "page turning" button to check the changes in various technical parameters during engine operation through the LCD display screen. After successful starting, the engine should be warmed up at idle speed. Only when the oil and water temperature of the engine reach 40 ℃ or above can acceleration and loading be carried out.
Press or adjust the acceleration/deceleration knob on the control screen to adjust the frequency of the unit to slightly higher than the rated frequency. Adjust the fine adjustment knob of the voltage regulator on the control panel to make the AC voltmeter at 400V, close the main switch, and the unit will supply power to the load. After the unit operates with load, if the voltage and frequency deviate from the rated value, adjust the speed knob and voltage setting potentiometer respectively to make the voltage and frequency reach the rated value.
The gas generator set can also operate automatically. For emergency automatic gas generator sets, the generator set should always be in a quasi start state (regular automatic pre lubrication, maintaining oil temperature and water temperature). After receiving a start command from the automatic control system (loss of mains power, overall power shortage, etc.), the unit will automatically start and automatically close and load after reaching the rated state.
The shutdown and startup of gas generator units can be operated from the machine side and control panel. The shutdown operation of the engine is usually carried out after the main switch has been opened. The basic process is the same whether operating on the machine, in the monitoring room, or automatically. After gradually unloading the load and opening the main switch during normal shutdown, set the speed selection switch to the "idle" position and raise the natural gas engine speed to 1500r/min. After cooling the unit according to the requirements of the natural gas engine maintenance manual, turn the "stop" knob to the stop position to stop the engine from working. After stopping the machine, place all electrical switches in the stop position, and restore each adjustment knob to the corresponding stop position for the next start.
