6 FAQs about [The generator air cooler has low air flow]

What are the different types of generator cooling systems?

Each generator set manufacturer offers different options for design of the cooling system. The two most common styles of cooling systems are closed loop and open loop systems. Closed loop systems incorporate cooling pump (s), cooling fan and radiator (s) located on a skid as an all in one unit.

Why is cooling air important in hydropower generators?

Studies of the cooling air in generators are of great importance especially in hydropower generators. The air flow path for typical hydropower generators is a closed system established by the generator housing. The air flow characteristics and its thermal behaviour are in turn affected by the generator components and their operating conditions.

How does a generator cooling system work?

An ethylene glycol based coolant is circulated through the cooling system components. Three common cooling system configurations are: Single Pump Single Loop (SPSL) – SPSL systems are common in smaller to mid-size generator applications. Operation for this system as follows: • Engine starts, direct drive pump is driven and fan clutch is rotating.

How does air temperature affect gen set cooling system sizing?

Altitude, air temperature and velocity greatly affect cooling ability and performance. Following are some rules of thumb that may be used in general gen set cooling system sizing exercises: For every 304.0m (1,000 feet) above sea level, deduct 1.38C (2 F) from the observed ambient temperature for a better indication of the air’s cooling ability.

What is the difference between a generator and a cooler?

The water flow in the original cooler makes two tube-passes for each tube-bundle. On the other hand, the water flow in the new cooler makes one tube-pass for each tube-bundle. The design and operating conditions of the generator keep the air flow rate m ˙ a for both coolers nearly fixed at an average value of 9.3 kg/s.

Why do generators need a cooling system?

Generators are typically efficient machines, but their high output generates unwanted heat that requires dissipation outside the machine. Professionally designed, cooling systems effectively remove this heat, preventing overheating and permanently damaging the equipment.
