When the air compressor is running, the smaller the exhaust volume is, but the total flow will not change. Only the compressed air flow decreases. In short, the exhaust pressure of the super pipeline air compressor is inversely proportional to the flow.

Due to insufficient end air, the rated pressure of the air compressor power supply increases. If the end air is sufficient, the power of the air compressor decreases to reach the rated pressure. The function of the frequency converter is to make the pressure of the air compressor work stably, without significantly adjusting the working pressure of the air compressor. In case of large-scale air compressor, the frequency converter can help protect the equipment and play a great role in the stability of flow and pressure, Small air compressors do not need to use frequency converters.

The super pipe clearance volume is the clearance when the cylinder head, bushing and piston top reach the top dead center. A space must be set between the piston and the valve and between the piston and the cylinder head to prevent collision. The larger the clearance volume of the air compressor, the more gas in the exhaust cylinder. The remaining gas will expand during suction, shortening the effective stroke of piston suction and reducing the suction amount. In other words, the external air entering the cylinder in each working cycle of the super pipe is reduced. In order to improve the efficiency of the air compressor, the clearance volume in the piston should be reduced as much as possible so that it does not collide with the cylinder head.

Due to the suction filter, the resistance of the suction pipe, the elastic force of the opening valve and the inertial force of the valve plate, the suction pressure in the cylinder is always lower than the external atmospheric pressure. Therefore, the amount of air in the cylinder decreases, and the pressure in the cylinder is greater than the pressure in the exhaust pipe and the cylinder. The air volume in the suction cylinder is small, and the exhaust pressure is higher than that of the large cylinder. Obviously, the suction and exhaust resistance will increase the power loss of the air compressor, reduce the efficiency and reduce the exhaust volume.
