Water-cooled And air-cooled-which cooling method of air compressor is better?

General air compressor selection, in addition to the displacement, pressure these two important parameters, the air compressor cooling method is also crucial. The cooling mode of air compressor is generally water-cooled and air-cooled. It is difficult to say which of these two methods is better or worse. It can only be said that it depends on the environment under which they are used.

The water-cooled cooling method is to use the fluidity and temperature difference of the cooling water to keep the temperature of the air compressor equipment within a certain range. However, water cooling equipment is used to install the cooling tower water pump, and the water cooling equipment is not too high and stable for the environment. If small equipment (below 50PH) is air-cooled, large equipment proposes that water cooling will be more stable. Its advantages and disadvantages are as follows:

Advantages:

Because the cooling water has a certain cleaning effect, it can clean the inside of the equipment when it flows inside the air compressor. Helps to extend the maintenance of equipment cleaning cycle and improve the quality of compressed gas;

The water cooler has good adaptability to climate change, and the water pressure can be increased or reduced to adapt to the strong change of temperature;

3, dusty environment, such as textile, spraying, carbon black, titanium dioxide and other industries, with water cooling machine more reliable;

4, the cooler of the water cooler, the oil side is easy to clean, the air cooler can not do.

Disadvantages:

1, limited by water resources, so the scope of application is relatively narrow;

2, the cooling water may contain calcium and magnesium plasma, and these things are easy to react in the cooler due to high temperature, and then form scale in the cooler, thus affecting the cooling efficiency of the cooler.

The air-cooled cooling method is to use the fluidity of the air to take away the heat, so that the air compressor is always kept in a suitable temperature range. Its advantages and disadvantages are as follows:

Advantages:

The great advantage of the air-cooled cooling method is that it is not affected by environmental factors and can be used in any area.

2, less capital investment, can be transferred.

Disadvantages:

1. If the surrounding air quality is not good, it is easy to pollute the entire air compressor and compressed air. Therefore, in order to avoid such a situation, it is recommended to load the filter equipment;

2, if used in a closed space, it is recommended to add into, exhaust equipment;

3. The cooling effect and quality are not as good as water-cooled.

If it is not in a particularly water-scarce environment, it is recommended to choose water-cooled. Because the air-cooled structure is simple and the investment is small, but due to the limitation of conditions, the heat dissipation effect is poor, and it is mostly used for small air compressors. Although the water-cooled type has a complex structure and high technical requirements, it has a significant heat dissipation effect, is easy to adjust, and works reliably. Therefore, large and medium-sized air compressors are mostly water-cooled.
