Common faults of diesel generator sets include engine failure to start, unstable fire, etc., which need to be eliminated according to specific reasons, such as charging batteries, cleaning fuel lines, etc. For electrical faults, it is also necessary to adjust the regulator or check the load. Professional maintenance is recommended to ensure safety.
There are many kinds of faults of diesel generator sets. We use technicians to analyze various faults, quickly and accurately judge faults, and reduce the loss of diesel generator sets. Here are some faults in the use of generator sets. And troubleshooting methods.
1. The engine cannot be started
|
Serial Number |
Cause of failure | Exclusion method |
|---|---|---|
|
① |
Insufficient battery voltage or discharge current |
Charge the battery and replace the battery if necessary |
| ② | Air or blockage in fuel line |
Loosen the bleed bolt on the diesel filter, pump it into the fuel with a manual oil pump until there are no bubbles, and replace the filter if necessary |
| ③ | Electrical fault |
Check the start switch for poor contact, check the start relay, replace if necessary, control module is faulty, replace if necessary. |
| ④ | Combustion chamber water inflow |
Analyze the reason, must contact the authorized service personnel, if there is water, please do not do any start attempt. |
2. The starting is normal, the engine does not catch fire or stops after starting, and the operation is unstable
| Serial Number | Cause of failure | Exclusion method |
|---|---|---|
| ① | There is air in the fuel line and the fuel cannot keep up | Remove fuel air as per instructions |
| ② | Insufficient intake air or the intake pipe is blocked | Check engine intake line and replace filter if necessary |
| ③ | There is no oil in the oil tank or the oil valve is not open. | Check the oil level of the oil tank and the oil valve. |
| ④ | Wiring error of shutdown solenoid valve or shutoff valve | Check whether it is in working condition |
| ⑤ | Injector failure | Check fuel injector pressure and injection status, replace if necessary |
In addition, other electrical faults of diesel generator sets, such as output voltage is too high or too low, output current is too large or no output current, etc., also need to be eliminated by adjusting the voltage regulator, checking the load or replacing damaged parts.
Please note that these are only common troubleshooting methods, and the specific operation should be determined according to the model, usage and failure phenomenon of the generator set. If you are not sure how to operate, it is recommended to seek the help of professional maintenance personnel to ensure safety and avoid further damage.
