Knowledge of diesel generator set
Weifang is known as the Power City of China, home to the largest, most complete and most technologically advanced power equipment industrial cluster in China. It stands as the core national base for China’s power equipment industry.
Weifang’s power equipment cluster is recognized as a National Advanced Manufacturing Cluster (only 25 advanced manufacturing in China).In 2023, the cluster’s revenue exceeded 450 billion RMB, accounting for roughly one third of China’s total power equipment output, ranking first nationwide for many consecutive years.It has nearly 800 large scale enterprises, covering automobiles, generator sets, agricultural machinery, construction machinery and other fields.
Weifang has formed a complete industrial chain:Basic components → Core parts → Power assembly → Complete machines. The local supporting rate exceeds 50%, almost every link — from casting, cylinder blocks and crankshafts to engines and complete machines — can be completed locally, greatly improving efficiency and reducing costs.
Traditional Power: Weichai diesel engines lead globally in technology and market share.
New Energy Power: Layout in hydrogen fuel cells, hybrid power and battery electric systems. Hydrogen fuel cell engines achieve 52%+ thermal efficiency, supporting heavy trucks to travel 800 km.
Intelligent Power: 5G smart agriculture, unmanned equipment and industrial internet applications rank among the top in China.
Weifang is a National Power Equipment Innovation Center and a Demonstration Base for New Industrialization.Power equipment is the backbone of Weifang’s industry, accounting for about 30% of the city’s industrial output and serving as the core engine of its economy.The products are exported worldwide, making Weifang the key representative of China’s power equipment going global.
Summary: Weifang is the heart of China’s power equipment industry.From traditional fuel to new energy, from components to complete machines, it leads in full industrial chain, full product coverage and top level technology — that is why Weifang is known as the Power City.
Our company is factory, we also have our own import-export company named SHANDONG SMART INTERNATIONAL CO.,LTD. however, some China traders use our factory's photos and videos to impersonate us as the actual factory in their foreign promotion.
Prime Power (PRP): Serves as the primary power source, suitable for areas without a grid (such as remote mining sites, oil fields, and island base stations). It can operate continuously for 24 hours, providing long-term stable power output. Emergency Standby Power (ESP): Functions solely as an emergency backup power source. Continuous operation should not exceed 12 hours, with a 10% overload permitted for up to 1 hour within any 12-hour period. It is used as emergency backup during grid power outages to support critical equipment (such as in hospitals, data centers, and office building elevators). Selection Recommendation: Prioritize selection based on the Prime Power rating to avoid long-term overload operation.
Yes, but it is not for free, you need to pay the production cost and logistic cost.
Yes, welcome to visit our company and talk about the cooperation. we are biggest factory of generator in our city.
we provide comprehensive OEM/ODM solutions tailored to the unique needs of global partners in the power equipment sector, covering the full lifecycle from product conceptualization to mass production and after-sales support.
For diesel generator maintenance, the battery charge and the generator engine coolant level are checked. In addition, the generator engine oil level and oil leakage control are performed. It is also necessary to look inside the generator engine tank to check whether there is enough diesel oil.
In theory, yes, but the efficiency will decrease and it may damage the pump. This will lead to reduced flow rate, increased stress on components, and engine overload. Please select a pump with a suitable rated head.
It will restrict flow, increase pressure loss, and reduce output. The pump may overheat, fuel consumption may rise, and issues like erosion and cavitation can occur.
The engine power should be sufficient to overcome the resistance of the water pump under the set flow rate and head. Refer to the power requirement curve provided by the manufacturer, while also taking into account the transmission system losses and the engine's load performance.
Check the fuel and oil levels, prime the pump to expel air, and connect the pipelines. Start the engine, let it idle before increasing speed, while monitoring pressure and flow.
It should be performed before and after each use. Check the fuel, engine oil, water source, and pipelines, and clean the water pump and engine after operation.
