Diesel Generator Set Open and Closed Cooling Systems

Diesel generator sets, as large-scale power generation equipment, have a relatively complex structural composition and working principle. Only by correctly mastering relevant knowledge can we better facilitate later use, maintenance, and upkeep. In terms of overall structure, the units can be divided into two types: open cooling cycle diesel generator sets and closed cooling cycle diesel generator sets.

ISimilarities between Open and Closed Cooling Cycles of Diesel Generator Sets:

Closed cooling cycle and open diesel generator sets have similar structural compositions, mainly consisting of a diesel engine, an AC synchronous generator, a control panel, and supporting devices composed of a common chassis, radiator, cooling fan, etc.

Differences between Open and Closed Cooling Cycles of Diesel Generator Sets:

1.Differences in Application Scope:

Closed generator sets are usually used in civil projects. Their main advantage is small floor space, but they have strict requirements for engine room ventilation. The unit placement area should have good ventilation to facilitate the normal operation of the unit.

Open generator sets are commonly used in industrial projects. Their main advantage is reducing the unit's noise and indoor temperature, which is beneficial to the normal operation and maintenance of the unit. They are generally used in high-power diesel generator sets, such as 630KW-2200KW Jichai diesel generator sets.

2.Differences in Functional Composition:

The closed cooling cycle diesel generator set has the diesel engine and the generator fixed on the same common chassis. The power output end of the diesel engine is directly connected to the generator rotor shaft through an elastic sleeve pin coupling, and the diesel engine drives the generator to work.

Open units do not have radiators and cooling fan devices, so the unit itself cannot independently complete the cooling cycle process. Users must set up their own cooling water heat dissipation devices when using them to meet the cooling water required for the diesel engine to work.

Due to their different characteristics, the two types of diesel generator sets have different application occasions and scopes. Therefore, correctly understanding and being familiar with the relevant differences is the basis for us to correctly use, maintain, and maintenance the generator sets, so that we can prolong the service life of our units.
