Diesel generators are indispensable equipment for the provision of prime or backup power to an industrial facility. If your facility relies on a diesel generator for power, you should consider hiring a diesel mechanic to diagnose and repair such equipment when a problem arises. Even if you use a diesel generator for providing backup power, you might need to enter into a maintenance contract with a generator vendor or hire a diesel mechanic for routine maintenance. You should use the owner's manual as a reference guide to maintaining your generator for optimal performance. Here are some ideas for maintaining and repairing diesel generators.
Routine Inspection -- Over time, a diesel generator's parts might start to experience wear and tear. The fuel system, electrical components, and exhaust components should be inspected regularly for repair or replacement of any worn out parts or leaks. A qualified technician should be assigned the task of inspecting a diesel generator to ensure all systems and components work seamlessly. A technician will use a manufacturer's manual, coupled with a checklist, to rule out any damage or faulty components. Regular inspection ensures that a generator is maintained according to the manufacturer's recommendations. Through regular inspection, small issues, such as oil leaks, can be detected and rectified early, which prevents costly repairs and replacement.
Oil Testing and Change -- In diesel generators, oil is a critical component that lubricates all mechanical parts and prevents overheating. Since you do not want to lose your huge investment because you skimped on oil change, you must always check the oil frequently. For instance, if your diesel generator sits idle without running because you do not need backup power frequently, then the oil will start to oxidise. In such cases, the oil might be clean, but oxidation may force you to change it before the due service date. The best way to know if the oil is oxidising is to conduct a laboratory test. Knowing the oxidation period of oil can help a technician to reschedule the oil change intervals.
Standby Power -- Generators that act as backup power must have a standby power system that kicks in when the main power goes out. If the battery runs out of power or is undercharged, then the generator might not start up properly. A technician should check the battery to ensure that it is fully charged. You should also clean the battery of any dirt, especially on the terminals.
