There are many precautions for the correct operation of workshop generator, such as preparation work before operation and startup precautions. I hope the following introduction can provide users with reference.
1、 Preparation work before operating workshop generator
Familiar with equipment manual: Operators must read and understand the generator's user manual or operation guide in detail, understand the performance, structure, operating procedures, and safety precautions of the generator.
security check:
Appearance inspection: Check whether the casing of the generator is damaged, deformed, or leaking, whether all bolts and nuts are tightened, and whether there are any loose parts.
Workshop generator ventilation inspection: Ensure that the ventilation openings of the generator are unobstructed
Fuel inspection: Check whether the fuel level in the fuel tank is sufficient and whether the fuel quality is qualified
Workshop generator oil inspection: Check if the engine oil level is within the normal range of the oil dipstick, and add oil promptly if it is insufficient.
Coolant inspection: Check if the coolant level is sufficient.
Workshop generator electrical system inspection: Check if the generator's wire connections are secure, free from damage or short circuits, and if the grounding wire connections are reliable.
Surrounding environment inspection: Check if the environment around the generator is safe, free of flammable and explosive materials, and keep the work area clean.
Personal protective equipment: Operators must wear labor protection equipment to protect their safety.
2、 Workshop generator startup operation
Preparation before startup: Set the resistance of the excitation variable resistor to the maximum position and disconnect the output switch. If there is a clutch, it should be disengaged.
Open the fuel valve to ensure normal fuel supply. Turn on the oil pump switch (if equipped) to ensure proper oil circulation.
Startup steps: Follow the startup steps provided by the manufacturer. After starting, let the generator run at low speed for 3 to 5 minutes, observe the operation of the engine, and ensure that parameters such as oil pressure and water temperature are normal. The generator should have no abnormal noise during the acceleration process.
After startup inspection: The power supply can only be provided to the outside after the generator runs stably and the frequency and voltage reach the rated values. When supplying power for the first time, the load should gradually increase and strive for three-phase balance.
3、 Workshop generator operation monitoring
Parameter monitoring: closely observe the operating status of the generator, including parameters such as oil pressure, water temperature, voltage, frequency, and current.
Abnormal situation handling: If any abnormal situation is found, such as abnormal noise, odor, rapid increase in water temperature, rapid decrease in oil pressure, etc., the machine should be stopped immediately for inspection and troubleshooting.
Load management: Strictly control the generator load to avoid overload operation. Allocate loads reasonably based on the output power of the generator and the power requirements of the load equipment, avoiding concentration on one generator.
4、 Workshop generator shutdown operation
Preparation before shutdown: Reduce the load first, gradually unload the load, and avoid sudden unloading of the load that may cause the generator output voltage to be too high and damage electrical equipment.
Shutdown steps: Return the excitation variable resistor to the high resistance position to reduce the voltage to a low value. Cut off the switches in sequence, including the generator power supply main switch, excitation switch, and neutral grounding switch. Stop the operation of the internal combustion engine.
Post shutdown inspection: Conduct routine checks on the unit, including the generator, diesel engine, cooling water, fuel, engine oil, etc., to ensure that there are no abnormalities.
Record the operation status, including startup time, running time, downtime, load situation, etc., for easy fault analysis and maintenance.
5、 Workshop generator daily maintenance and upkeep
Regular inspection: Regularly check the ventilation openings and radiators of the generator. Is the connection of each component of the generator firm.
Regular maintenance: According to the manufacturer's recommendations, regularly replace vulnerable parts such as oil, filters, and air filters. Regularly maintain the generator, including cleaning the casing, inspecting the electrical system, testing performance indicators, etc.
Storage management: If the generator needs to be shut down for a long time, it should be stored in a dry, well ventilated place and appropriate protective measures should be taken, such as covering it with canvas.
6、 Workshop generator safety precautions
Anti electric shock: Operators should maintain a safe distance from live equipment to avoid electric shock accidents. It is strictly prohibited to carry out maintenance and upkeep work during the operation of the generator. If maintenance is required, the power must be cut off first and a conspicuous warning sign must be hung, and a dedicated person must be assigned to supervise.
Poison prevention: The generator generates harmful gases such as carbon monoxide during operation. It is strictly prohibited to use the generator in a closed space to prevent carbon monoxide poisoning.
Fire prevention: Oil or other flammable materials should not be placed near the generator, and fire-fighting equipment should be installed. In case of a fire, the power should be cut off first and immediately extinguished. Dry type fire extinguishers, carbon dioxide fire extinguishers, etc. should be used to extinguish live equipment. It is strictly prohibited to use water to extinguish fires When the generator is running, it is forbidden to touch rotating parts and high-temperature areas to prevent burns or mechanical injuries.
Workshop generator operators must undergo professional training, be familiar with the structure, principles, and operating procedures of the generator, and possess certain electrical knowledge and safety awareness. By strictly adhering to the above precautions, the safe and reliable operation of the workshop generator can be ensured, providing stable power supply for production activities in the workshop.
