When purchasing diesel generator sets, we should purchase them according to our own needs, rather than just purchasing the required power size. The following selection parameters are commonly used for your reference. If you have more detailed technical requirements, please contact us, and technical personnel will provide you with detailed answers.

(1) Determination of capacity: Based on the long-term continuous operation output power of the unit, determine whether it can meet the load calculated by the project. In addition, it is necessary to confirm the actual output power with the manufacturer to avoid virtual calibration machines that cannot be used in the future.

(2) Determination of the number of units: In common usage environments, only one unit can meet the required power, but in special places such as mining and data centers, due to high power demand, it is usually more than two units to ensure continuity of power supply and adapt to changes in the electricity load curve. It is recommended that the economic operating state of the diesel engine be between 75% -90% of the rated power, in order to achieve better performance. Therefore, for special places, the power and number of units should be determined to ensure the continuity of power supply.

(3) Determination of speed: Generally, high-speed units with a speed of 1000-1500 rpm are used, while low-speed units with a speed of 300-350 rpm are suitable for use as marine main engines.

(4) Voltage determination: The output voltage of the generator is the same as that of the emergency generator set, usually 400V. For some projects with high power consumption and long transmission distances, high-voltage generator sets can be selected.

After confirming the above data, you can basically choose the generator that is suitable for you. In addition, you can determine the commonly used and backup machines based on your usage time. If you need a generator, you can contact us and we will recommend the unit that is suitable for you.
