Shandong Kecheng Electric Power Equipment Co., Ltd. is located in Weifang, the city of power in China, with a registered capital of 18 million yuan. It is a private enterprise specializing in the research, development, manufacturing, and sales of diesel generator sets. The company boasts a comprehensive management system, strong R&D capabilities, and complete production and inspection equipment. Its main products include engines, generators, diesel generator sets, enclosed diesel generator sets, intelligent electrical systems, mobile pump trucks, and more than one hundred other specifications. Diesel generator sets range from 20KW to 3000KW, with diesel engines sourced from Volvo, Cummins, Mercedes-Benz, Deutz, as well as domestic brands such as Shangchai, Jichai, Yuchai, and Weichai. Generators are available from brands like Stanford, Marathon, and Lantian. The products are sold across the country and are widely used in enterprises, hospitals, hotels, ports, bridges, railways, road construction, mining operations, and fire backup power supply sites.
Using high pressure common rail fuel injection technology (such as Weichai Boudouan 20M61 unit), combined with efficient turbocharged intake system, the fuel utilization rate is increased by 15%-20%, the transient response speed is optimized, and the engine does not stall at 0-100% load.
Some imported models (such as Cummins QST19 series) are equipped with patented electronic speed regulator, synchronous accuracy up to ±0.25Hz, support 50Hz power grid stable operation, meet the high precision power supply requirements of semiconductor manufacturing and so on.
Mainstream imported models meet Chinas non-road phase 3, EPA2 and other emission standards, and some high-end products (such as Caterpillar units) use ADEC electronic management system to reduce nitrogen oxide emissions by more than 30%.
Volvos environmentally friendly units are equipped with electronic injection technology, which takes into account low fuel consumption and low carbon operation, and is suitable for green scenarios such as hospitals and data centers.
The original imported unit (such as Mitsubishi Mitsubishi 1800KW) adopts SAE standard pre-installed shock absorber base, and the overhaul life is up to 15000-30000 hours, and the first overhaul cycle is 40% longer than that of domestic units.
Some models (such as Doitz series) optimize the crankcase ventilation design, support-30℃ low temperature cold start, plateau area power attenuation rate is less than 5%.
Conway (Cummins): covers 800KW-3500KW high pressure units, QST30 series (800KW) uses four-stroke supercharged intercooling technology, suitable for industrial main power supply; KTA50-GS8 (1160KW) is equipped with independent ECU system, supporting multi-machine grid connection.
Caterpillar (Caterpillar): Unidesign and manufacture engines and control systems, leading the industry in durability, suitable for extreme environments such as mines and oil fields.
Mitsubishi (Mitsubishi): 1800KW unit is equipped with original engine + Inge/Stanford generator, which supports manual/automatic control system switching, and the noise value is less than 75dB (A).
Daewoo: Compact (20% smaller than similar models), with a load resistance of 200%, suitable for backup power supply in commercial buildings.
Weichai: Baudouan 20M61 is the worlds first 5MW high-speed unit with a overhaul life of 15 years and is customized for data centers; 6M31 has a single power of 880KW and can be loaded by 50% at one step.
Continuous load scenario (such as factory owner supply): priority should be given to the model with rated power of 80% or more than the peak demand (such as Cummins 2000KW standby unit).
Emergency backup scenarios (such as hospitals): It is recommended to configure ATS self-starting system, and the switching time is less than 10 seconds.
The purchase cost of imported units is 30%-50% higher than that of domestic units, but the advantages of fuel economy (such as the fuel consumption of Mitsubishi units is less than 198g/kWh) and maintenance cycle are significant.
It is recommended to choose the original factory supporting control system (such as Weichai independent ECU) to reduce the risk of compatibility failure.
Industrial sector: semiconductor manufacturing, oil field exploitation (high altitude/explosion-proof models required).
Commercial facilities: data center (high voltage units above 5MW), hotel/mall (silent variable frequency units).
Emergency power supply: hospital, fire station (fully automatic unattended control panel +ATS switching).
Certification compliance: the original factory certificate (such as Cummins QST19 series with factory test report) shall be checked for imported units.
After-sales service: preferentially choose the brand with spare parts warehouse in the local area (such as Weichai and Cummins) to shorten the maintenance response time.
Through technical adaptation and brand selection, imported diesel generator sets can significantly improve power supply reliability, especially suitable for high precision and high load industrial and commercial scenarios.
