Gas generator sets, as efficient and clean energy equipment, may encounter various issues during operation. Timely detection and resolution of these faults not only ensure smooth operation but also extend the service life of the equipment. This article introduces the causes and solutions for several common faults in gas generator sets to help users better manage and maintain their systems.

1. Ignition System Faults

Common Symptoms

1. Difficulty starting or failure to start
2. Unstable operation, frequent stalling

Causes

1. Spark plug fouling or severe wear
2. Loose or aged ignition system wiring
3. Faulty ignition control module

Solutions

1. Regularly inspect and replace spark plugs. High-quality, durable spark plugs are recommended to extend replacement intervals.
2. Ensure secure wiring connections and replace aging components to maintain stable ignition system performance.
3. Perform routine maintenance on the ignition module and replace it promptly if faults are detected.

2. Gas Supply and Mixing Faults

Common Symptoms

1. Insufficient power and engine sluggishness
2. Abnormal exhaust emissions

Causes

1. Unstable or low gas supply pressure
2. Uneven gas-air mixing ratio
3. Carbon deposits or blockages in the mixer or throttle

Solutions

1. Check the gas supply system to ensure stable pressure and regularly service adjustment equipment.
2. Adjust the mixing ratio and use precise control systems to optimize the mixture.
3. Clean the mixer regularly to keep the pipelines clear and prevent contaminants from affecting operation.

3. Cooling System Faults

Common Symptoms

1. High-temperature alarms
2. Abnormal coolant consumption or leakage

Causes

1. Blocked radiator or cooling tank
2. Faulty water pump or aging cooling pipes
3. Insufficient or degraded coolant quality

Solutions

1. Clean the radiator and cooling tank to prevent blockages from affecting heat dissipation.
2. Inspect the water pump and piping regularly and replace aging components as necessary.
3. Refill or replace high-quality coolant to maintain effective cooling and avoid overheating.

4. Output Power Abnormalities

Common Symptoms

1. Significant fluctuations in output power
2. Unstable voltage or frequency

Causes

1. Improper parameter settings in the control system
2. Malfunctioning or poorly performing excitation system
3. Load fluctuations exceeding the generator set’s capacity

Solutions

1. Review control system settings and optimize operating parameters to ensure stable performance.
2. Conduct regular maintenance on the excitation system to keep it in optimal condition.
3. Distribute the load reasonably to avoid large fluctuations impacting the generator set.
