Diesel generator daily maintenance steps, how to maintain diesel generator set daily?

1. The generator set and the control panel are protected by electricians and professional maintenance personnel, and the proposition of large-scale maintenance or small-scale maintenance is put forward according to the operation status, and each connection point and actuator connecting rod are lubricated regularly to check whether the fixed points are reliable and firm, and the bolts are strong and loose.

2. Full-time maintenance personnel carry out generator maintenance and protection according to the needs of generator protection, and make specific records of the operation process and the number of replacement parts, and fill in the generator test run record form.

3. The inspection content is as follows:

1) Smooth system: check the liquid level and oil leakage; Replacement of oil, oil filter;

2) Air inlet system: check the air filter, pipe position and connector; replacement of air filters;

3) Exhaust system: check the exhaust blockage and air leakage; Discharge mufflers, sediment and water;

4) Some generators: check whether the air inlet is blocked, the terminals, insulation, oscillation and each component is normal;

5) Replace the oil, various oil separators and air separators according to the actual situation;

6) The control screen is cleaned once a month, and the maintenance and protection operations are checked and implemented, and the protection process is summarized and the protection statement is completed according to the operation parameters before and after the protection;

7) Cooling system: check the radiator, hose and connector; Water level, belt tension and water pump, etc., regularly clean the cooler fan filter screen and cooler fan bearing;

8) Fuel system: check the fuel level, speed limiter, oil pipe and connector, fuel pump. Drain (sediment or water from fuel cylinders and oil-water separators) and replace diesel filters;

9) Charging system: check the battery charger, battery electrolyte level, density (check and charge the battery once a week), appearance, main switch, wiring pipe and indicator light;

10) Automatic control equipment: check whether the automatic equipment of the simulated power supply, power failure, and starting oil engine is normal;

11) Clean the unit, and clean the periphery of the cooler every month. After viewing the above jobs, turn on the machine pack for 15 minutes (or run with load).

1. Precautions:

1. The generator set should be placed in a stable and safe place, and have good ventilation conditions (ambient temperature 40), which is convenient for the unit to dissipate heat.

2. It is strictly forbidden to place it outdoors in the sun and rain to avoid the invasion of water droplets, metal fragments or other sundries.

3. Ensure that the generator set is well grounded, and the power output cable should have sufficient cross-sectional area, good contact, and connect the cable correctly.

4. The load used in the generator set for power generation must be balanced by three-phase electricity, and it is strictly forbidden to run under overload for a long time, and the power should be used in strict accordance with the calibrated power.

5. The motor shall regularly check the wear of the brushes (except for brushless) and the lubricating oil of the bearing chamber and the linkage with the engine flywheel.

6. The unit has been running for 50 hours for the first time to change the oil, and then for every 200 hours of cumulative operation, it is recommended to use CF-4 diesel engine oil.

7. If the unit is not used for a long time, the battery connection line must be removed, and the battery should be fully charged once a month to ensure that there is sufficient power to start the engine.

Second, the start-up operation:

1. For the first time, there is no need to carry out long-term idle running-in and several seepage stoves (the diesel engine has been cold ground before leaving the factory). It can be used directly at loads below 60%.

2. Before starting, the diesel engine should be filled with cooling water and filled with oil to the scale on the oil dipstick. The air switch should be disconnected in the open position.

3. Start the engine, and pay attention to the oil pressure, it is forbidden to accelerate when the oil pressure does not rise.

4. Acceleration to 1500r min, no-load voltage: 400V, frequency: 50Hz, close the generator air switch to the closing position, and connect in turn.

Electricity is used under load.

3. Shutdown operation:

Before the unit is shut down, the electrical load should be cut off first, and the output air of the motor should be switched to the opening position, and the engine speed should be changed.

1500r min to idle speed 500-700r min, cool down for 2-5 minutes, then stop the engine.

Fourth, the unit operation monitoring:

1. The operation of the unit must be operated by a special person and the display of each instrument must be checked at any time (the normal range values of each parameter are: oil pressure, water temperature 50 -96, voltage 400V, frequency 50Hz).

2. Observe whether the instruments and indicators of the control panel are normal, and pay attention to whether the operating sound of each part of the machine is normal and the linkage parts are.

No loose. 3. It is strictly forbidden for the unit to shout at the faulty operation, and if an abnormal situation is found during operation, it should be stopped for inspection immediately, reported to the supervisor in time, and inquired about the factory's technology. In the tank.

Shenzhen generator.

1. Purpose. Ensure the integrity and safe operation of diesel generator sets, and ensure that they can be put into use in time when the mains power is out to ensure normal power supply.

2. Scope of application.

Diesel generator sets.

1) Routine maintenance of diesel generator sets.

1. Check the water level and oil level once a day;

2. Clean the outer surface of the unit and the environment of the machine room once a day.

2) Monthly maintenance of diesel generator sets:

1. Clean the outer surface of the unit;

2. Check whether the speed regulating rod is flexible and lubricate the connecting points;

3. Replace the cooling water, measure the pH value before and after replacement (the normal value is, and make a measurement record, and if necessary, the water treatment worker should be notified to cooperate);

4. Check the tension of the fan belt and the charger belt, and adjust it if necessary;

5. Cooperate with the emergency power generation test of electrical work, check whether the reading, temperature and loudness of each instrument are normal when the diesel engine is running, and make a good operation record.

3) Quarterly maintenance of diesel generator sets

1. Check the air flow resistance indicator, clean the air filter when it is red;

2. Release the diesel water and clean the first-stage diesel filter;

3. It is necessary to pay attention to lubricating the fan pulley and belt tensioner bearing;

5. Check the tightening of the main external connecting bolts.

4) Annual maintenance of diesel generator set:

1. Cooperate with the electrician to carry out parallel load operation and check the operation;

3. Test and inspect the axis, open the file, and make a record;

4. Disassemble the inspection cover to observe and inspect the shaft and cylinder barrel;

5. Dosing and cleaning the cooling system (notify the water treatment worker to cooperate);

6. Check the quality of the engine oil and change the oil when necessary;

7. Clean the second-stage diesel filter;

8. Clean the oil filter;

9. After every 500 hours of operation, the following items will be added:

a. Replace the filter element of the second-stage diesel filter;

b. Change the oil;
