The Dongfeng Cummins JHK-24GF diesel generator set is a high-performance backup power unit with a primary power output of 24 kW. This unit is equipped with a Dongfeng Cummins (DCEC) original imported engine, model 4B3.9-G2, renowned for its compact structure, low fuel consumption, and high durability. The entire unit is designed as a single unit by professional manufacturers (such as Jianghao), featuring a brushless all-copper generator and intelligent control system. It is widely used in factories, construction sites, hospitals, hotels, and communication base stations, serving as an ideal choice for primary or backup power.
Performance characteristics：
Powerful Performance:Utilizing a Dongfeng Cummins 4B3.9-G2 engine with turbocharging technology, ensuring ample power reserves even at high altitudes or in harsh operating conditions.
Fuel Economy:Employing high-pressure injection and electronic speed control technology, it boasts low fuel consumption and lower total lifespan costs.
Stable and Reliable:Equipped with a brushless all-copper generator (Stanford/Marathon brands available), and AVR automatic voltage regulation, it provides clean sine wave power suitable for precision electronic equipment.
Low-Noise Operation:The unit can be equipped with a silent canopy or an ultra-quiet enclosure, effectively reducing operating noise and meeting environmental protection requirements.
Intelligent Control:Standard configuration includes a self-starting control panel with multiple protection functions such as oil pressure, water temperature, and overspeed protection, enabling automatic switching between mains power and AC power (ATS).
Maintenance and Care
To ensure the unit is in good condition and to extend its service life, it is recommended to follow these maintenance guidelines.
Note: For units that have been idle for extended periods, it is recommended to run them under no-load or light-load conditions for 10-15 minutes each month to maintain lubrication of mechanical components and charge the battery.
Applications
The JHK-24GF, due to its moderate power and reliability, is primarily suitable for the following scenarios:
Commercial Buildings: Fire elevators, emergency lighting, and security systems in shopping malls, office buildings, hotels, and high-rise residential buildings.
Industrial Production: Power supply for construction machinery in small factories, farms, and construction sites.
Public Services: Backup power for hospitals, schools, communication base stations, and bank branches.
Outdoor Operations: Temporary power needs for mining exploration, field construction, and ship auxiliary machinery.
FAQ (Frequently Asked Questions)
1. Q: What should I do if the JHK-24GF generator set has difficulty starting?
A: First, check if the battery voltage is sufficient and if the battery terminals are loose; second, check if there is fuel in the fuel tank and if the fuel filter is clogged; in winter when the temperature is low, check if the preheating system is working properly.
2. Q: What is the fuel consumption of the generator set?
A: Under full load operation, the fuel consumption rate of this generator set is approximately 209-228 g/kW·h. Actual fuel consumption will vary depending on the load rate, but typically at 24kW full load, the fuel consumption is approximately 5-6 liters per hour.
3. Q: How is the automatic start function implemented?
A: An ATS (Automatic Transfer Switch) is required. When a mains power outage is detected, the ATS will send a start signal to the generator set control panel, and the generator set will start automatically. After the voltage stabilizes, it will automatically switch power supply.
4. Q: What is the warranty period for the generator set?
A: Manufacturers typically offer a 1-year warranty or a cumulative operating time of 1000 hours from the date of manufacture (whichever comes first). For specific terms, please consult your purchaser or refer to the warranty card included with the unit.
5. Q: Can it be converted into a silent generator set?
A: Yes. The JHK-24GF supports customized production, and a silent canopy (super silent type) can be selected to reduce noise pollution, making it suitable for residential areas or areas near hospitals with strict noise control requirements.
