Why Do Some EVOTEC Generators Last 10 Years Like New, While Others Fail in Just 3? The Key Difference Lies in Daily Maintenance!
Whether it's a small emergency backup unit or an industrial-grade power generator, proper maintenance not only prevents sudden breakdowns but also ensures peak performance. Based on years of experience, EVOTEC’s service engineers have compiled this "Generator Maintenance Guide", covering everything from basic checks to in-depth servicing to help extend your equipment’s lifespan.
Before Starting: A 3-Minute "Checkup" Is a Must
Weekly inspection for oil stains, rust, damaged cable insulation, and loose bolts (both on the generator and mounting base).
EVOTEC generators feature an anti-corrosion coating, improving rust resistance by 40% compared to standard models, reducing inspection frequency and maintenance costs.
During Operation: Monitor Key Signals
Listen for sounds: Normal operation produces a steady hum; metallic grinding or unusual noises indicate bearing or rotor-stator issues—shut down immediately. EVOTEC’s high-precision bearings and structural design minimize noise and abnormal sounds, making it easier to detect problems.
Smell for odors: A burning smell may signal a short circuit. EVOTEC’s high-temperature-resistant, short-circuit-proof wiring reduces such risks.
Watch the load: Ensure current doesn’t exceed the rated value. For low power factor loads, excitation current must stay within rated limits. For unbalanced three-phase loads, the highest phase current should not exceed the rated value, with imbalance kept below 25%.
Check vibrations: Excessive vibration accelerates wear on bearings, gears, and other components, shortening their lifespan from tens of thousands of hours to just a few thousand.
After Shutdown: Final Steps Before Leaving
Clean the body: Wipe off oil with a dry cloth; use compressed air to remove internal dust.
Lubricate parts: For high-power open bearings, apply specialized grease every 1,500–2,000 hours (refer to EVOTEC’s manual).
Storage: Outdoor units need rain covers; indoor storage requires dry, ventilated spaces away from corrosive materials. EVOTEC’s IP23+ protection rating ensures durability even in harsh conditions.
Maintenance cycles vary slightly between different generator models. Please refer to the product manual for specific guidelines. In case of complex malfunctions, do not attempt disassembly yourself—contact EVOTEC’s after-sales team. With over 100 service centers nationwide, our engineers provide a 2-hour response and 24-hour on-site repair.
A well-maintained generator becomes your most reliable backup in critical moments. Attention to detail ensures every kilowatt-hour is delivered with confidence!
