The basic theoretical knowledge of air that everyone who uses an air compressor should understand

1 What is air? What is normal air? 　　 Answer: The atmosphere around the earth, we are accustomed to call it air. 　　The air under the specified pressure of 0.1MPa, temperature of 20°C and relative humidity of 36% is normal air. Normal air is different from standard air in temperature and contains moisture. When there is moisture in the air, once the moisture is separated, the air volume will be reduced.

What is the basis for the rated flow when selecting the filter

When selecting a filter, the rated capacity should not be selected according to the diameter of the pipe, but the nominal flow of the filter (nameplate flow) should be selected according to the volumetric flow of the compressed air passing through the filter.

What is the reason why the freezer is not cooling

It may be that the capillary is blocked and the refrigerant flow does not enter the evaporator. It may also be that the refrigerant needs to be replenished or the refrigeration system is leaking. If the buffer tube inside the compressor ruptures, there may be loose screws or it will cause no cooling. It is also possible that the expansion valve and the discharge valve are not adjusted properly, causing cold air to leak out. Need to check one by one, and then take the medicine.
