Common internal failures in generator rentals and their main maintenance plans often include: traditional longitudinal differential maintenance, traditional transverse differential maintenance, fundamental frequency vertical zero-sequence voltage maintenance, secondary harmonic current maintenance in motor rotors, and standard braking system longitudinal differential maintenance, etc. These traditional protective measures can selectively remove common fault components from the power supply system, reduce the level of damage to the power supply system, restore the normal operation of non-problematic components, and reflect abnormal operational conditions of electrical components. However, due to various reasons, the proper operation rate of maintenance components for facilities like generator rentals and transformers in the power supply system is generally low, often below 70%. Therefore, it is necessary to analyze these protective measures in order to find corrective actions.

Diesel generator sets for rent, during operation, generate high temperatures due to the combustion process, causing ash polymers to adhere to components like valves, valve seats, injectors, and piston tops. Failing to clean these promptly can increase fuel consumption and severely affect the normal operation of the diesel engine. Generally, it is recommended to clean them every 4-6 months.

Generator rental: Do not remove the fuel filter screen from the fuel filler cap while refueling. (Stop the engine when refueling and smoking is prohibited nearby); Refueling is forbidden when the engine is running or still hot. The fuel line valve must be closed before refueling; Be careful not to let dust, dirt, moisture, and other foreign matter mix with the gasoline during refueling.
