Oil-injected Screw Air Compressor Cooler--air-cooled And Water-cooled
Oil-injected screw air compressor cooler--air-cooled and water-cooled
There are two cooling methods for oil-injected screw air compressor coolers - air-cooled and water-cooled.
working principle
Air-cooled type - using ambient air as the cooling medium, sweeping across the finned tube, using the fluidity of the air to take away heat, cooling or condensing the high-temperature fluid in the tube, and keeping the temperature of the air compressor within a certain range.
Water-cooled type - using water as the cooling medium, using the fluidity and temperature difference of the cooling water and the high-temperature fluid in the pipe to alternately cool and heat to achieve the cooling effect, so that the temperature of the air compressor equipment can be kept within a certain range.
working environment
Air-cooled type-mainly uses air as the medium, and has lower requirements on the working environment, and can be used in any environment
Water-cooled type-mainly uses water as the medium, and needs to have the condition of water source.
How to choose air-cooled and water-cooled coolers, you can choose which cooling method to choose according to their advantages and disadvantages and actual use requirements
Advantages and disadvantages of air-cooled and water-cooled
air-cooled advantage:
1. Less capital investment and can be transferred
2. The biggest advantage of the air-cooled cooler is that it is not affected by environmental factors and can be used in any area.
shortcoming:
1. If the surrounding air quality is poor, 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 filter equipment
2. The cooling effect changes with the temperature. The effect is good in winter and poor in summer. Just like the air conditioner at home, the outdoor temperature is higher in summer, and the cooling effect will be poor
3. If it is used in a closed space, it is recommended to install air intake and exhaust equipment
4. The cooling effect is not as good as water-cooled
Water-cooled advantage:
1. Since the cooling water has a certain cleaning effect, when it flows inside the air compressor, it can clean the inside of the equipment. Helps extend the maintenance and cleaning cycle of equipment and improve the quality of compressed gas
2. The water chiller has good adaptability to climate change, increasing or decreasing the water pressure, and adjusting the inlet water temperature can adapt to strong changes in temperature
3. Dusty environment, such as textile, spraying, carbon black, titanium dioxide and other industries, water cooler is more reliable
4. The cooler of the water-cooled machine, the oil-cooled part is easy to clean, and the air-cooled machine cannot do it
5. The cooling effect is good, and the influence of environmental factors is small
shortcoming:
1. Restricted by water resources, the scope of application is relatively narrow
2. The cooling water may contain calcium and magnesium ions, and these minerals are prone to chemical reactions due to high temperature in the cooler, and will form scale in the cooler, thus affecting the cooling efficiency of the cooler
3. The investment cost of early projects increases and cannot be transferred
How to maintain and clean the cooler
After the air compressor air-cooled cooler is used for a long time, the fine particles and flocs in the air will be attached to the fan hood, affecting and reducing the cooling effect.
Calcium, magnesium and other bicarbonate substances in the water-cooled cooler of the air compressor will form scale in it, which will increase the inlet and outlet temperature of the air compressor, and the air and lubricating oil cannot be cooled to the predetermined temperature. So it is very important to clean the air compressor cooler.
Air-cooled cooler cleaning
Stop the air compressor equipment and confirm that the pressure has been released, and pull down the main power switch. Open the air guide cover to clean the cover, or remove the cooling fan. Use compressed air to blow back the dirt, and then take the dirt out of the windshield; if it is dirty, spray some degreaser before blowing. When the above methods cannot be used to clean the air compressor cooler, it needs to be removed, soaked or sprayed with cleaning fluid and cleaned with a brush. Fit the cover or cooling fan.
Water-cooled cooler cleaning
Stop the air compressor equipment and confirm that the pressure has been released, and pull down the main power switch. Disconnect the cooling water inlet and outlet pipes. Inject cleaning solution to soak or flush with pump cycle. Rinse with water. Install the cooling water inlet and outlet pipes. (Clean once a year)
Vrcooler can provide plate coolers, tube coolers, coolers are made of copper and stainless steel, reliable quality, stable performance, sealing performance of each connection part, good cooling effect of the air compressor
