Key Points to Note about the Fresh Air Provision for the Operation of 3 1250KVA Cummins Generators In the power supply systems of many industries today, the combined use of 3 1250KVA Cummins generators is not uncommon.
However, the demand for fresh air behind their stable operation is often overlooked. Recently, industry experts have pointed out that for such high-power generators during operation, fresh air plays a crucial role like a "lifeline." On the one hand, it is used to cool the generator compartment to deal with the huge amount of heat generated during operation, avoiding overheating and shutdown. On the other hand, it timely replenishes sufficient oxygen for the combustion of the diesel engine to ensure efficient operation, and it can also dilute harmful exhaust gases and optimize the air quality in the machine room.
It is understood that Cummins has provided clear guidelines. According to the calculation in the technical manual, considering the cooling ventilation and combustion requirements, about 75 - 90 m³/min of fresh air is required for the three generators. Moreover, aspects such as the design of the air inlet and outlet channels, dust and rain prevention, noise elimination, and negative pressure control cannot be underestimated. If the fresh air provision is neglected, the temperature in the machine room will rise sharply, triggering a high-temperature alarm or even shutdown. Incomplete combustion will lead to a decrease in power and an increase in carbon deposition, and the accumulation of harmful gases will also pose a threat to the safety of personnel. The industry calls on relevant enterprises to, based on the actual situation of the machine room, combine with Cummins' technical data, or seek the help of professional teams, to carefully design a suitable fresh air system to ensure the reliable and long-term operation of the generators.
