What is the reason for the leakage fault of the cooler in the air compressor?

       Atlas Copco air compressor is a world famous brand with a high market share. During the operation of Atlas Copco air compressor, in order to reduce the power consumption of the air compressor and ensure the reliable operation of the air compressor, intercoolers are set between all levels. With the increase of the number of intercoolers supporting the air compressor, a cooler series suitable for various working conditions and different models will naturally be formed. In the intercooler after the first stage, the cooling water pressure is usually higher than the gas pressure. Therefore, if the first stage intercooler leaks, the cooling water will enter the gas side, and water will be entrained in the gas, which will significantly increase the amount of water separated from the first stage oil-water separator. According to the above phenomena, the judgment of intercooler leakage can be made. When the exhaust volume of the air compressor system decreases, the pressure of the air compressor system begins to rise. When the controller receives the signal of pressure rise, it begins to gradually reduce the opening of the intake valve. At this time, the exhaust volume of the screw machine also decreases, and of course, the current of the motor also decreases. When the air consumption of the system increases, the system pressure begins to decrease. When the controller receives the signal of pressure reduction, it gradually increases the opening of the intake valve. At this time, the exhaust volume of the screw machine also increases to the full output.
