Ce guide par HuaQuan couvre les principales raisons pour lesquelles le générateur tombe en panne. Et nous avons un guide étape par étape pour vous permettre de diagnostiquer ce qui ne va pas avec le générateur et comment le réparer dès que possible..
Causes courantes: Le générateur ne produit pas d’électricité
Lorsque le moteur du générateur ne brûle pas, l'alternateur est incapable de produire de l'électricité.
- Réservoir de carburant vide: Avec le défectueux, la jauge à essence ne fonctionne pas, les gens interprètent à tort que leur réservoir de carburant est plein même lorsqu’il est complètement sec.
- Carburant vieux ou contaminé: L'essence tombe généralement en panne après quelques mois de stockage. Il se transforme en un vernis collant qui obstrue le moteur et les autres composants du système. Avec du gasoil, la condensation de l'eau arrêtera complètement le processus de combustion.
- Le filtre à carburant se bouche: S'il y a de la rouille ou des débris de réservoir sur le filtre, le carburant n’arrive pas aux injecteurs du moteur ni au carburateur.
Problèmes électriques
Il y a des moments où le moteur sonne parfaitement. Mais le générateur ne produit pas d'électricité.
- Câblage défectueux: Des trous, les rongeurs entrent et rongent les fils. Soit la vibration du moteur desserre la connexion entre l'alternateur et votre prise de courant.
- Connexions desserrées ou corrodées: Sans entretien, the rust and green oxidation settle in the terminal connection, which fluctuates the power flow.
- Blown fuses or circuit breakers: During a short circuit, le Générateurs built in safety Breakers immediately tripped down to cut off power production.
Problèmes de moteur
In modern generators, the manufacturing companies install protective sensors to shut off power production. It helps the users save their generator engine from self destruction.
- Oil levels too low: En général, there is a low oil shutdown sensor installed in generators. If the oil inside the crankcase is low, it will immediately turn off the ignition process.
- Overheating or engine malfunction: When the intake lowers are clogged or cooling fans are blocked, the engine seizes under heavy load.
- Air filter blockages: Dry air filters cause insufficient oxygen to supply the engine. Finalement, the generator fails to reach the maximum RPM necessary to produce electricity.
Échec du système de démarrage
Souviens-toi, if the engine does not start, you will not get any electricity.
- Faulty starter motor: The engine makes a sizzling or hard grinding sound when the starter is burnt out or jammed.
- Batterie morte: Moderne générateurs électriques do have an automatic 12V battery. If the battery is dead, the motor will not start.
Processus de dépannage étape par étape du générateur qui ne produit pas d'électricité
Étape 1: Vérifiez le système de carburant
- Ensure there’s enough fuel: Experts recommend frequently checking your fuel tank level with a clean dipstick or flashlight. Do not rely on your fuel gauge levels.
- Inspect fuel lines and filter for clogs or damage: keep an eye on the rubber lines. If there are any clogged inline filters, immediately replace them.
- Drain and replace old fuel: When your fuel turns 6 months old or has a foul smell, drain your fuel tank and carburetor. Refill it with fresh fuel mixed with a high quality stabilizer.
Étape 2: Inspecter la batterie
- Tester la tension de la batterie: Set the DC voltage with a digital multimètre. A perfectly working 12V battery has 12.6 volts. If the voltage is below 12V, connect it to the charger.
- Check for loose connections or corrosion: Regularly clean any crusty or white acid buildup around the battery terminal with the wire brush. Après le nettoyage, make sure to tighten the cables.
Étape 3: Examinez les disjoncteurs et les fusibles
- Reset or replace any tripped breakers: Have you checked the control panel? Are all the breaker buttons in place? Sinon, push it back. Maintenant, turn on the switch. If the breaker button pops up again, your generator is currently having a short circuit that can destroy your appliances or system wiring.
- Replace blown fuses: Check for any blown fuses or blades in the engine wiring. Ask for some professional help to replace them with the right, compatible blades.
Étape 4: Testez le câblage et les connexions
- Inspect for any loose or disconnected wires: When the generator is turned off, double check the thick wires connected from the alternator to the control panel receptacles.
- Look for signs of wear or corrosion: Find out any loose grounding nuts, scorch marks or melted insulation.
Étape 5: Examiner la bougie d'allumage et le système d'allumage
- Check spark plug for wear or damage: It’s time to check your engine spark plug. If the plug has a thick black carbon soot or is wet with oil, the engine will not run when needed.
- Replace if necessary: Spark plugs are available at low prices in the market. If somehow the ceramic insulator is cracked or your metal electrodes are worn out, replace them with new ones.
Étape 6: Testez la charge et la sortie
- Ensure the generator is not overloaded: For a load bank test, unplug every appliance from the generator. Turn on the generator with zero load. Once it reaches the normal power, plug all the appliances one by one. Do not overload the machine, as it will immediately trip the safety breaker.
- Verify proper voltage output: Avec le multimètre, check the power generator voltage output. It must be 120V or 240V.
Comment prévenir les problèmes d'alimentation avec votre générateur
- Regular maintenance routines: Follow the recommended schedule for oil filter, spark plug and oil change; the manufacturer suggests for maximum performance.
- Fuel and battery care tips: Connect your electric batteries with the smart charger when not in use. Add fuel stabilizers inside your fuel tanks to add some extra shelf life. Always run your generator weekly under a load, so fresh fuel passes through your engine carburetor.
- Cleaning and inspecting wiring: Keep your generator in a cool, endroit sec. Chaque année, open your generator’s control panel to double-check whether all the wire terminals are tight and dust free.
Quand appeler un professionnel
- Persistent power issues after troubleshooting: Have you followed all the troubleshooting steps listed above? Toujours, your generator is not producing electricity? It’s time to call a professional, as the quick, simple DIY tips and tricks are not fixing the problem.
- Complex electrical or engine problems: If the automatic voltage regulator fails or the residual magnetism is no longer working, call a certified technician to fix this problem. They replaced the burnt out alternators with fresh ones.
- Major parts replacement: Never try to rebuild the generator carburetor or replace your engine’s internal gears. This needs professional help. Leave it to them.
Conseils de sécurité lors du dépannage d'un générateur
- Disconnecting power before working on the generator: Habitually remove the spark plug wire. Disconnect any negative battery cables before working around the electrical panels.
- Porter un équipement de protection: Always wear safety glasses to protect yourself from any battery acid or separate fuel. When working with hot engine parts, it’s better to use heavy work gloves.
- Keeping the work area clean and dry: Do not troubleshoot your power generator in rain or snow. Aussi, never try troubleshooting a power backup unit standing in a puddle, as it will increase the chances for electrocution.
Pensées finales
Souviens-toi, generators are not set in forget machines. On time, scheduled routine maintenance is the only way to keep your setup available for reliable power during any emergency call.
Quick and on time diagnostics for tripped breakers, low oil levels, or dirty spark plugs can help you save the day without paying for unnecessary repair bills.
Foire aux questions
Why does my generator not produce electricity while running?
It might be that your generator has a failed Automatic Voltage Regulator (AVR). Or the circuit breaker is tripped. Parfois, the residual magnetism inside the alternator’s jamming leads to a generator not producing power.
Does an overloaded generator stop power production permanently?
Non. Généralement, an overload will ultimately trip the internal circuit breakers to keep your generator from crashing. It’s better to unplug the heavy loads. Alors, reset the breaker to restore your generators’ power production ability.
How will I know if my alternateur de générateur is broken or not?
Suppose your system engines run smoothly at normal speed. Every breaker is in place. But the multimeter is reading a zero voltage signal at the outlets; either the internal AVR or the alternator has failed.
Si, after following all the troubleshooting steps, your generator is still down. Contacter HuaQuan immediately for professional diagnostic services and an upgrade to our ultra reliable power system you can always trust during an emergency.
