Diesel Generators Uses And Functions
A diesel generator is a backup power source that combines a diesel engine with an electric generator. Diesel generators are used in industrial facilities, large buildings, hospitals, and utility companies for backup and emergency power. They are perfect for many commercial and industrial needs.
Here’s how it works:
- Diesel fuel burns in the engine and mixes with air. The mixture ignites when compressed.
- This combustion moves pistons, turning chemical energy into mechanical energy.
- The mechanical energy powers the electric generator, which then produces electrical energy.
Investing in a diesel generator is a smart way to protect your operations, avoid downtime, and keep things running efficiently when power is lost.
Key Tips for Keeping Your Diesel Generator Running Longer
Following are the ten best tips that help improve your generator’s life, prevent breakdowns, and reduce fuel consumption:
1. Regular Maintenance
You must follow the manufacturer’s servicing and maintenance schedule to ensure your generator works well for longer. You can keep a detailed maintenance log for tracking all services and repairs. One key task is changing the oil at recommended intervals. If the oil level is low, the engine can overheat and shut down, causing serious damage.
Whether you have a standby or a portable diesel generator, you must check the oil level at least once a week and top it off when required. Regular maintenance of a diesel generator also includes checking and replacing fuel filters and oil filters. Besides that, you must check coolant levels, evaluate battery condition, and inspect belts and hoses.
2. Quality Fuel Management
Low-quality fuel can cause problems like clogging and buildup in the carburetor, which could eventually need to be replaced. The fuel grade you use directly affects how well your generator performs. So, you must choose high-quality diesel fuel to avoid such problems. Fuel Logic can deliver top-grade diesel fuel directly to your location.
Furthermore, regularly test the fuel to ensure it hasn’t degraded, and consider adding a diesel fuel additive to improve performance and protect your engine. Store diesel fuel in a clean, sealed container and keep it in a cool, dry place to prevent contamination and degradation.
3. Cooling System Care
The diesel generator’s coolant system prevents the engine from overheating. You should regularly inspect the radiator, coolant levels, and hoses to keep your engine within the optimal temperature range. Flush the cooling system and replace the coolant as recommended by the manufacturer to prevent corrosion and buildup. You should use distilled water or the correct coolant mixtures to prevent mineral buildup.
4. Lubrication and Oil Management
Changing the oil and filters as suggested by the manufacturer, helps your engine last longer and improves efficiency. You must keep the engine well lubricated and replace the oil filter after the recommended period. Whether you have a large or small diesel generator, follow the manufacturer’s guidelines and use the correct grade of oil and filters. Dirty oil can clog the engine and cause it to wear out faster.
5. Battery Care
Weak batteries can cause slow or failed engine starts. Sulfation, which is the buildup of lead sulfate crystals, is a common issue with lead-acid batteries. Therefore, you should keep the battery terminals clean and free of sulfation to ensure reliable performance. Moreover, to keep the battery charged and ready, don’t let it run out completely. Use a maintenance charger to keep it fully charged when not in use. Also, clean battery terminals and ensure connections are tight.
6. Air System Maintenance
Air quality is important for your diesel generator because the engine compresses air and mixes it with fuel. A clogged air filter can block airflow, causing the engine to strain. Your generator’s air filter prevents dirt and debris from entering the engine. Check the air filter at least once a month and replace it if needed. Also, clean the air intake system after regular intervals to ensure proper airflow.
7. Electrical System Check
The best diesel generator is one that provides uninterrupted power, and that’s possible only when the electrical system is in excellent operational condition. To keep your diesel generator running longer, check the spark plugs and electrical system at least once a year. Replace old or dirty spark plugs to ensure the engine starts efficiently. Also, inspect the belts that drive the alternator and other parts. Replace any worn or loose belts annually to prevent breakdowns.
8. Load Management
Overloading a generator can cause overheating, extra wear, and breakdowns. You should perform load bank testing to ensure your generator runs perfectly. The load bank testing system uses an artificial load to stimulate real operating conditions and check whether the generator can handle its output. It helps remove carbon buildup, verify electrical connections, and identify issues before they become a complete power failure.
9. Environmental Considerations Using Diesel Generator
It’s important to ensure your diesel generator has proper ventilation to prevent overheating. However, during harsh conditions or severe winters, it becomes mandatory to cover the generators using suitable covers or enclosures. If a permanent enclosure isn’t possible, use a generator tent or cover designed specifically for winter conditions. These covers are weather-resistant and protect against snow and ice, keeping your generator running efficiently in the outside environment.
10. Professional Inspections and Servicing
Another key tip to keeping your diesel engine running longer is regular professional inspections and preventative maintenance. Hire skilled technicians to identify issues you might miss and perform timely repairs. However, if you don’t have a technician on-site, you can take your bulky generators to a service center using diesel generator trailers.
Furthermore, have a plan for emergency repairs to minimize downtime and ensure your generator stays operational whenever you need it.
