Common faults and treatment methods of diesel generator sets,learn more about the generator sets to make sure the power generator run well.
Fault 1: Unable to start
cause:
1. The circuit is not working properly
2. Insufficient battery power
3 Corrosion of battery connector or loose cable connection
4 Poor cable connection or faulty charger or battery
5 Starter motor failure
6 Other possible failures
Approach:
1. Check the circuit
2. Charge the battery and replace the battery if necessary
3. Check the terminals of the cable, tighten the nuts, and replace the severely corroded connectors and nuts
4 Check the connection between the charger and the battery
5 Ask for help
6 Check the start/stop control circuit of the control panel
cause:
1. Insufficient fuel in the engine cylinder
2. There is air in the fuel circuit
3. The fuel filter is clogged
4. The fuel system is not working properly
5. Air filter clogged
6. Low ambient temperature
7. The governor is not working properly
Approach:
1. Check the fuel tank and fill it up
2. Remove the air from the fuel system
3. Replace the fuel filter
4. Replace the air filter
Fault 2: Low speed or unstable speed
cause:
1. The fuel filter is clogged
2. The fuel system is not working properly
3. The governor is not working properly
4. The ambient temperature is low or not preheated
5. AVR/DVR is not working properly
6. The engine speed is too low
7. Other possible failures
Approach:
1 Replace the fuel filter
2 Check the preheating system of the engine, and make the engine run dry and make it run
Spend
Fault 3: The voltage frequency is low or the indication is zero
cause:
1. Clogged fuel filter
2. The fuel system is not working properly
3 The governor is not working properly
4. AVR/DVR is not working properly
5. The engine speed is too low
6. Indicating instrument failure
7. Instrument connection failure
8. Other possible failures
Approach:
1. Replace the fuel filter
2. Check the engine governor
3. Check the meter and replace the meter if necessary
4. Check the instrument connection circuit
Trouble 4: Attachment does not work
cause:
1. Apply overload trip
2. The attachment is not working properly
3. Other possible failures
Approach:
1 Reduce the unit load and measure whether the ambient temperature is too high
2 Check the generator set output equipment and circuit
Fault 5: The generator set has no output
cause:
1. AVR/DVR work
2. Instrument connection failure
3. Overload trip
4 Other possible failures
Approach:
1. Check the meter and replace the meter if necessary
2. Reduce the unit load and measure whether the ambient temperature is too high
Trouble six: low oil pressure
cause:
1 The oil level is high
2 Lack of oil
3 The oil filter is clogged
4 The oil pump is not working properly
5 Sensor, control panel or wiring failure
6. Other possible failures
Approach:
1. Apply to release excess oil
2Add oil to the oil pan and check for leaks
3 Change the oil filter
4 Check whether the connection between the sensor, the control panel and the grounding is loose or disconnected
5. Check if the sensor needs to be replaced
Fault 7: High water temperature
cause:
1. Overload
2. Lack of cooling water
3. Water pump failure
4. Sensor, control panel or wiring failure
5. The tank/intercooler is clogged or too dirty
6. Other possible failures
Approach:
1 Reduce the unit load
2 After the engine cools down, check the coolant level in the water tank and whether there is any leakage, and supplement if necessary
3. Whether the sensor needs to be replaced
4 Check and clean the water tank intercooler, check whether there are debris before and after the water tank that hinders air circulation
Fault 8: Overspeed
cause:
1 meter connection failure
2 Sensor, control panel or wiring failure
3. Other possible failures
Approach:
1. Apply to check the connection circuit of the instrument
2 Check whether the connection between the sensor and the grounding of the control panel is loose or disconnected, and check whether the sensor needs to be replaced
Fault nine: battery alarm
Cause: 1
1. Poor cable connection or faulty charger or battery
2. Other possible failures
