In the maintenance of the screw air compressor cooler, the cooler should be cleaned regularly according to the environmental conditions to make the air compressor work at normal temperature to ensure that the machine operates stably and has a long service life. When the cooler is dirty At this time, the exhaust temperature of the air compressor will increase.

Generally, the outside of the air-cooled cooler should be cleaned every 1500 hours, and the water side of the water-cooled cooler should be cleaned every 1500 hours. Regular cleaning of the cooler has the following advantages:

1. Make the unit always work at the ideal working temperature (below 95 ℃), which is beneficial to the performance and life of the machine.
2. The dirt can be removed by using a cleaning fluid, otherwise when the dirt is thick, the cleaning work is quite troublesome, and the cooler needs to be disassembled and the cleaning work can be completed with the help of mechanical methods.

Cleaning steps for air-cooled coolers
1. Shut down and confirm that the pressure has been released, pull down the main power switch.
2. Open the air duct to clean the cover, or remove the cooling fan.
3. Use compressed air to blow the dirt down, and then take the dirt out of the wind deflector; if it is dirty, spray some degreasing agent before blowing. When the above methods cannot be used to clean, the cooler needs to be removed, soaked or sprayed with cleaning fluid, and cleaned with the help of a brush (wire brush is strictly prohibited).
4. Install the cover or cooling fan.

Cleaning steps for water-cooled coolers
1. Shut down and confirm that the pressure has been released, pull down the main power switch.
2. Disassemble the cooling water inlet and outlet pipes.
3. Inject the cleaning solution to soak or circulate flush with a pump (the backflushing effect is better).
4. Rinse with clean water.
5. Install the cooling water inlet and outlet pipes.

When the scale of the oil cooler is serious and the cleaning by the above method is not ideal, you can remove the oil cooler separately, open the two end covers, and use a special cleaning steel brush or other tools to remove the scale. When cleaning the heat dissipation side of the cooler cannot effectively reduce the temperature, the oil side needs to be cleaned. The method is as follows:
1. Shut down and confirm that the pressure has been released, pull down the main power switch.
2. Disassemble the oil inlet and outlet pipes.
3. Inject the cleaning solution to soak or circulate flush with a pump (the backflushing effect is better).
4. Rinse with clean water.
5. Blow dry with dry air or use dehydrated oil to remove water.
6. Install the oil inlet and outlet pipes
