The correct operation precautions of Yuchai generator set cover multiple aspects, and the following introduction is made in the hope of providing reference for users.
1、 Preparation before starting Yuchai generator set
Environmental inspection:
Ensure that the generator set is placed in a stable and safe location with good ventilation conditions (ambient temperature ≤ 40 ℃) for easy heat dissipation of the unit. It is strictly prohibited to place it outdoors in places that are exposed to sunlight and rain, to prevent water droplets, metal fragments, or other debris from entering.
Appearance inspection:
Is there any damage or missing parts on the exterior of the Yuchai generator set, and are the screws loose. Whether the wiring is firm and correct, to prevent the engine from colliding with the wires due to vibration.
System check:
Check if there is enough fuel stored in the fuel tank of Yuchai generator set, and turn on the switch from the fuel tank to the diesel engine fuel pump. Use the fuel hand pump to remove the air in the fuel system.
Check the oil level to ensure that the oil is within the normal range and the anti pull cylinder. Is the water tank filled with water. Is the voltage regulator in the small position and is the automatic air switch in the open circuit position.
2、 Yuchai generator set start-up operation
Preparation before startup:
Before starting the engine, it should be filled with coolant and oil to the mark on the dipstick. The air switch should be disconnected in the open position.
Startup steps:
Start the generator set according to the requirements of the operation manual to avoid frequent start-up and reduce equipment wear. After starting the engine, pay attention to the oil pressure, which should be within the range of 1.8~6.0kpa. Do not accelerate when the oil pressure has not increased.
3、 Inspection and adjustment during the operation of Yuchai generator set
Observation instrument:
After the unit is running, a dedicated person needs to operate and check the instrument display, including oil pressure, water temperature, voltage, frequency, etc. Observe whether the instruments and indicator lights on the control screen are normal.
Monitor sound:
Pay attention to whether the sound of each part of the machine is normal and whether the connecting components are loose.
Adjust the load:
When operating external electrical appliances, three-phase power balance must be maintained, and long-term overload operation is strictly prohibited.
4、 Shutdown operation of Yuchai generator set
Unloading load:
Before stopping the machine, all electrical loads should be cut off and the output air switch should be disconnected to the open position.
Reduce the speed:
Reduce the engine speed from 1500r/min to idle speed of 500-700r/min.
Cooling down:
After cooling down for 2-5 minutes, the engine can be turned off and stopped.
5、 Safety precautions for Yuchai generator set
Electrical safety:
When cleaning, maintaining, or repairing the generator set, it is necessary to first stop the machine and disconnect the negative switch of the battery or remove the battery connection cable. When welding is required for assembling the generator set, it is strictly prohibited to use the generator set for grounding or earthing, in order to avoid welding high currents that may damage the internal electrical components of the generator set.
Fire prevention measures:
During the operation of the generator set, the exhaust pipe and muffler may overheat. Fire resistant insulation materials should be used during installation and use, and flammable materials should be kept away. Smoking, sparking or other ignition behaviors are not allowed near batteries and fuel.
Personal protection:
It is recommended to wear ear protection equipment in high noise environments where the generator set operates for a long time. Avoid ingestion and skin contact with fuels, water tanks, lubricants, electrolytes, and other liquids. Once splashed with these liquids, rinse immediately with plenty of water.
The correct operation of Yuchai generator set involves multiple aspects such as preparation before starting, starting operation, inspection and adjustment during operation, shutdown operation, daily maintenance, and safety precautions. Operators must strictly comply with relevant regulations and precautions to ensure the safe and stable operation of the generator set.
