Difference between open and closed cooling cycles for diesel generating sets

The diesel generator unit is already familiar, in various production and life occasions, we will use diesel generators to generate electricity, to provide users with great convenience, at present, the market can be classified into diesel generators, can be divided into closed cooling cycle Diesel generator sets and open cooling cycle Diesel Generator sets two major categories. They have different characteristics, so there are some differences in the use process.

The closed-type cooling cycle Diesel Generator set consists of diesel engine, AC Synchronous generator, Control Panel and auxiliary device composed of common chassis, radiator and cooling fan.

The structure of the open cooling cycle Diesel Generator sets is basically the same as that of the closed-type units, the main difference is that the open unit does not take the radiator and cooling fan device, so the unit itself can not independently complete the cooling cycle process, users in use must set their own cooling water cooling device to meet the diesel engine work required cooling water. Open-type cooling cycle is generally used in high-power diesel generators, such as: Chai Diesel Generator Set (630kw-2200kw).

The closed cooling cycle Diesel Generator set is fixed on the same common chassis by the diesel engine and the generator, and the diesel power output end is directly connected with the generator rotor pumped through the elastic sleeve pin coupling, which is driven by the diesel engine to work. The free end of the diesel engine is fitted with a radiator and cooling fan. The cooling fan is connected with the free end of the crankshaft by the fan drive and the diesel engine is driven by the fan and the cooling water is forced. The radiator is connected with the internal cooling system of the diesel engine through the inlet and outlet pipe to form an independent closed-loop cooling system to provide cooling water for the diesel engine to work. Users do not need to set up a separate cooling water cooling device.

Different classification characteristics of the diesel generator set its use and maintenance is still a difference, so treatment of different types of diesel generator sets or need to understand the characteristics of the generator set, according to the characteristics of the corresponding maintenance, which can greatly improve the use of diesel generators stability.
