Answer: Compressed air users should not only choose the appropriate air compressor capacity to meet the gas consumption of the gas-using equipment, but also pay attention to the system pressure to meet the requirements of the gas-using equipment at all times, and make timely judgments on the reasons for the reduction of system pressure.
Generally, the output pressure of industrial air compressors is 0.69MPa, and the pressure delivered to the equipment use point is at least 0.62MPa. This means that the air compressor has an unloading pressure of 0.69MPa and a cylinder loading pressure (or system pressure) of 0.62MPa.
If the system pressure is lower than 0.62MPa, or does not gradually rise to the unloading pressure of 0.69MPa, more air may be needed. Of course, first check whether there is a large leak. If you are sure that there is no leak in the system, you should check whether the unloading and control system of the air compressor are operating normally.
If the compressor must work at a pressure higher than 0.69MPa to provide a system pressure of 0.62MPa, it is necessary to check whether the pipe size of the distribution system is too small, or the air post-processing equipment is not cleaned in time, causing the pressure drop to increase.
