Knowledge of diesel generator set- What is difference between kW and kVA?
The primary difference between kW (kilowatt) and kVA (kilovolt-ampere) is the power factor. kW is the unit of real power and kVA is a unit of apparent power (or real power plus re-active power). The power factor, unless it is defined and known, is therefore an approximate value (typically 0.8), and the kVA value will always be higher than the value for kW.
In relation to industrial and commercial generators, kW is most commonly used when referring to generators in the United States, and a few other countries that use 60 Hz, while the majority of the rest of the world typically uses kVA as the primary value when referencing generator sets.
To expand on it a bit more, the kW rating is essentially the resulting power output a generator can supply based on the horsepower of an engine. kW is figured by the horsepower rating of the engine times 0.746. For example if you have a 500 horsepower engine it has a kW rating of 373. The kilovolt-amperes (kVA) are the generator end capacity. Generator sets are usually shown with both ratings. To determine the kW and kVA ratio the formula below is used.
0.8 (pf) x 625 (kVA) = 500 kW
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.
