diesel generator with low oil level automatic protection

Diesel generators play an important role in different fields due to their high efficiency, durability and economy.

Features of diesel generator:

• Electric start design: Convenient electric start makes the operation simple and easy, especially in the environment of lack of external power, providing a convenient way to start.
• Engine structure: Equipped with a single-cylinder, forced air-cooled, four-stroke, direct injection OHV (overhead valve) engine, designed to be lightweight, high power, with better fuel economy, reducing fuel consumption.
• High strength frame: Made of high quality metal pipe material, combined with rack type overall welding design, the frame has high strength, good stability, excellent heat dissipation performance, ensuring safety and efficiency in long time operation.
• Automatic welding technology: The use of OTC automatic welding process enhances the stability and shock resistance of the rack, strengthens the interface, reduces risk of fracture, and ensures long-term stable operation of the equipment.
• Low noise design: Large silencer and dynamic balancing rotor design, with shock absorbing shell and frame, greatly reduce the noise and vibration of the generator, so it can adapt to more stringent working environments.
• Automatic protection device: Equipped with engine low oil pressure and low oil level automatic protection device to avoid engine damage, extending the equipment’s life.
• Overload protection system: Built-in non-fuse circuit breaker, effectively avoiding overload and overcurrent; capacitor voltage regulator ensures voltage output stability and protects equipment.
• Motor design: All copper wire damping motor provides high quality power output, stable waveform, small distortion, strong overload capacity and high reliability.
• Automatic voltage regulator system: Equipped with AVR automatic voltage regulator, monitoring load changes in real time and automatically adjusting excitation current for stable voltage output.
• Large-capacity fuel tank: 40L metal fuel tank provides longer operation, allowing 8–12 hours of continuous work per refueling, reducing downtime and improving efficiency.
• High-efficiency air filter: Effectively isolates dust and impurities, keeps the engine clean, extending service life and reducing maintenance frequency.
• Starting battery: Strong anti-overcharging ability and high starting current ensure fast start and suitability for various working environments.
• Convenient mobile design: Standard with four wear-resistant nylon casters for long life and abrasion resistance, making transport and movement easy to meet on-site needs. Brake universal wheels can be customized for better fixing and mobility.

Working principle of diesel generator:

Diesel generators produce electricity through the working principle of a diesel engine. Diesel fuel is precisely injected into the combustion chamber through injector nozzles, where it mixes with air and ignites. The engine drives a piston through a four-stroke cycle (suction, compression, combustion, exhaust), which converts chemical energy into mechanical (rotational) energy via the crankshaft. This power is transferred to the rotor of the generator, generating electrical energy in the stator through electromagnetic induction. The AVR (automatic voltage regulator) adjusts output voltage to match load requirements, ensuring stable power supply. To protect the engine, low oil pressure and low oil level automatic protection devices are included to ensure safe shutdown in case of insufficient oil.

Application areas of diesel generator:

• Building construction: On sites without grid power, diesel generators provide reliable power for construction equipment, lighting, and more.
• Outdoor activities: Camping, wilderness exploration, photography and other activities benefit from temporary power for various devices.
• Emergency Power: As an emergency source, diesel generators supply temporary power to hospitals, commercial buildings, and residential areas during outages.
• Agriculture: Power for farm irrigation equipment, agricultural machinery, supporting agricultural production.
• Industrial applications: For small factories, production lines, and mobile/flexible industrial equipment.
• Transportation: Backup power for ships, railroads, and other transportation, ensuring stable operation of critical systems.
