What should be paid attention to in the safe operation of diesel generator set?

1. It is strictly forbidden to start the diesel engine with load.

Before starting the diesel engine, it should be noted that the output air switch of the generator must be turned off. After the diesel engine of the ordinary generator set starts, it will go through 3-5 minutes of idle operation (about 700 rpm), and the temperature is low in winter, and the idle operation time should be appropriately extended for a few minutes. After the diesel engine starts, it is necessary to observe whether the oil pressure is normal and whether there is abnormal phenomena such as oil leakage and water leakage, (under normal circumstances, the oil pressure must be above) If any abnormality is found, it should be stopped immediately for maintenance.

If there is no abnormal phenomenon, the speed of the diesel engine is increased to the rated speed of 1500 rpm, and the generator display frequency is 50Hz and the voltage is 400V, and the output air switch can be closed and put into use. The generator set is not allowed to run no-load for a long time. If the no-load operation is carried out for a long time, the diesel fuel injected by the diesel engine injector will not be completely combusted, resulting in carbon deposits, resulting in valve and piston ring leakage.

In addition, the automatic generator set does not need to idle operation, because the automatic unit is generally equipped with a water heater, so that the diesel engine cylinder block is always kept at about 45, and the diesel engine can be powered normally within 8-15 seconds after starting.

2. Always pay attention to the operating status of the diesel generator.

During the work of the diesel generator set, always pay attention to the possible occurrence of a series of faults, especially the changes in important factors such as oil pressure, water temperature, oil temperature, voltage, frequency, etc. In addition, it should be noted that there is enough diesel, such as fuel interruption during operation, which objectively causes load shutdown, which may lead to damage to the generator excitation control system and related components.

3. It is strictly forbidden to stop with load.

Before each shutdown, the load must be cut off gradually, then the output air switch of the generator set must be turned off, and finally the diesel engine must be slowed down to idle for about 3-5 minutes before stopping.

As a kind of power generation equipment, diesel generators need to pay attention to the following safety matters when using: Environmental safety: The generator should be placed in a fireproof, explosion-proof, and well-ventilated place, and the operator should not smoke or use an open flame near the generator.

Morning safety of electric wheel disturber: Before use, check whether the power supply voltage, frequency, wiring, ground wire, etc. meet the requirements to avoid personal injury caused by electrical failure. Gas Safety:

Generator fuel storage and oil inlet pipelines should be regularly inspected to prevent safety accidents caused by oil leakage and oil pipe aging. Operation safety: The generator should be operated in accordance with the requirements during operation, and should not be overloaded to avoid overload, short circuit and other problems caused by failure.

Maintenance safety: Generators need regular maintenance and replacement of wear parts to ensure their normal operation. When carrying out maintenance, the power supply should be cut off first to prevent the occurrence of electric shock accidents.

Personal safety: Operators should wear labor protection equipment that meets the requirements, such as safety helmets, protective gloves, protective shoes, etc. In the process of operation, the operating procedures should be strictly followed to avoid the occurrence of personal injury.

In short, when using diesel generators, we should pay attention to safety and reasonable use, abide by operating procedures, and maintain regularly to ensure the normal operation of the equipment and personal safety.

Dear, the following are the safety precautions for diesel generators: 1. Before using diesel generators, make sure you are familiar with all the guidelines and warnings in the operating manual and safety instructions. 2. Before using the diesel generator, make sure that all electrical equipment has been properly grounded and that the equipment itself is not damaged or malfunctioning.

3. Before using the diesel generator, make sure that the oil in the fuel system will not leak, and also make sure that there is no combustibles around the generator. 4. When using diesel generators, appropriate personal protective equipment should be used, such as gloves, Anfengji shoes, goggles, etc. 5. When using the diesel generator, the equipment should be kept dry to avoid rainwater or water immersion into the equipment.

6. When using diesel generators, the electrical system, silver key fuel system, cooling system and mechanical system of the equipment should be checked regularly to ensure the normal operation of the equipment. 7. When using diesel generators, they should be avoided in closed spaces to ensure that the equipment has adequate ventilation. 8. When using diesel generators, you should follow the operation steps in the operation manual and safety instructions to avoid unnecessary operation errors.

9. Before stopping the diesel generator, the equipment should be run no-load for a period of time to ensure that the equipment stops normally. 10. When storing diesel generators, they should be avoided in flammable and explosive places, and at the same time, the equipment should be regularly maintained and kept bright to ensure the normal operation of the equipment.

1. Do not change the performance and specifications of the diesel generator set.

2. Do not smoke when filling the tank with fuel.

3. To remove the spilled fuel, the materials soaked in fuel must be moved to a safe place.

4. Do not add fuel to the fuel tank when the diesel generator set is running (except when it is specially needed).

5. Do not add oil or adjust or wipe the engine when the diesel generator set is running (unless the operator is specially trained, even so, it should be very careful to avoid injury).

6. Do not adjust the parts that you don't understand.

7. The exhaust system should not leak, otherwise the exhaust of the harmful diesel generator set will affect the health of the operator.

8. When the diesel generator set is running, other personnel should be in the safety zone.

9. Do not let loose clothes and long hair close to the rotating parts.

10. The diesel generator set should be kept away from the rotating parts when working.

11. Note: When the diesel generator set is working, it is not easy to distinguish whether some parts rotate or not.

12. If the protective device is removed, do not start the diesel generator set.

13. Do not open the radiator nozzle cover of the hot diesel engine to prevent the high-temperature coolant from spraying out and hurting people.

14. Do not use hard water and coolant that will corrode the cooling system.

15. Do not let sparks or open flames approach the battery (especially when the battery is charging), because the gas escaping from the battery electrofluid is extremely flammable. Battery electro-hydraulics are very dangerous to **, especially to the eyes.

16. When repairing the electrical system or diesel engine, the battery wiring should be disconnected first.

17. The diesel generator set can only be operated through the control box and in the correct working position.

1. No. 0 light diesel oil is used for diesel; The engine oil is specified to use 15W-40CD grade engine oil (or according to the requirements of the diesel engine manual).

2. The starting temperature is +5 or above; When the water and oil temperature heating device is provided, the starting temperature is -15; When the unit is used below 0, antifreeze and other low-temperature starting measures should be used.

3. The noise coefficient of the unit: 85 95db(a), in line with international standards.

4. Pressure regulation mode: automatic or manual.

5. Attention of users in cold areas: According to the change of temperature, the oil, diesel and coolant should be adjusted appropriately to ensure the normal operation of the unit.

6. With the continuous update of the product, if there is any change or change in the sample parameters, the random file shall prevail

1. The boiling point of the cooling water of the unit in the state of diesel generator use is higher than that of ordinary water, so when the diesel generator is running, do not open the pressure cover of the water tank or heat exchanger. In order not to harm personal safety, it is necessary to cool down the unit and release the pressure before maintenance.

Yanan A Yanan Group: R & D and production of diesel generator sets and fuel cells).

2. When inspecting, discharging or filling diesel fuel, please be especially careful not to swallow or inhale diesel oil, and the same is true for engine oil. Do not inhale the exhaust gas emitted by the unit.

3. Install a fire extinguisher in the most appropriate position. Use the correct type of fire extinguisher, referring to the regulations of your local fire unit. Foam fire extinguishers should not be used for fires caused by electrical equipment.

4. Do not place unnecessary grease and lubricating oil on the diesel generator. Accumulated grease and lubricating oil can cause the generator set to overheat, damage the engine, and pose a high risk of infection.

5. The surrounding area of the diesel generator should be kept clean, and no sundries should be placed. Remove all debris from the generator set and keep the floor clean and dry.

The diesel generator set must be operated by personnel who are familiar with the structure of the unit and master the safety operation procedures. New or newly overhauled diesel units should be run for 60 hours according to the regulations, and the necessary maintenance should be done.

For new or long-term unused generators before they are put into normal operation, they must go through strict inspections, mainly to check the winding insulation, wiring, etc., if there is any discrepancy, it is necessary to deal with it.

After the diesel engine starts, the speed should be slowly increased, and the no-load operation from low speed to rated speed can be carried out under the premise of checking and confirming that everything is in good condition. When running at no load, focus on checking the oil pressure, whether there is abnormal noise, excitation current, three-phase voltage change, etc., and stop the machine immediately for inspection if there is any abnormal situation. After ascertaining the situation, start again.

If everything is in order, it is ready for operation. The operator should closely monitor the changes of the instrument on the control screen, whether it is within the permitted range, and make corresponding adjustments.

When operating, the operator should keep a safe distance from the live equipment and wear labor protection equipment. If there is a power failure, the branch switch should be disconnected first, and then the main switch should be disconnected, and then the four-pole double-throw knife switch should be switched. When sending electricity, the order is reversed.

Normal shutdown should first unload part of the load, then break the main switch, and finally turn off the diesel engine, it is not allowed not to pull off the main switch, and the diesel engine will be turned off and the power will be cut off by itself. After the shutdown, the unit is routinely inspected, and the operation status (work diary) is recorded.

In the unlikely event of an electric shock, the power switch should be cut off quickly, or the power supply should be quickly disconnected or disconnected from the power supply with an insulator. Then the rescue was carried out and the doctor was called to the scene to rescue him. In the event of a flood of electrical equipment, the power supply should be cut off immediately, and the local power supply station should be reported to the local power supply, and then the fire should be extinguished.

Dry fire extinguishers, carbon dioxide fire extinguishers, etc. should be used to extinguish live equipment, and water should not be used.
