Advantages Of Single Stage Air Compressor

739 Words2 Pages

Single stage air compressors consists of a single piston which reciprocates in a cylinder, driven through a connecting-rod and crank mounted in a crankcase. As to compress and pump air to the storage tank, the piston receives power from main shaft through crankshaft and connecting rod. A flywheel/belt wheel is fitted on the crankshaft which is driven by electric motor or diesel engine. It supplies uniform motion throughout the cycle of operations. In single piston stroke, air is compressed to its final pressure. The compressed air then provides rotation power for pneumatic tools.

Also V1-V4 is the effective swept volume where the fresh air from atmosphere is sucked in. The effective swept volume V1-V4 control the mass of air flowing through the compressor.
If any restriction is placed on the delivery of the air compressor, then the delivery pressure of the air compressor will increase. From the diagram, we can say that the new delivery pressure is P5. Then the operating cycle will be 1567, where 6-7 is the clearance expansion of the air and the effective swept volume is V1-V7. Thus the effective swept volume (V1-V4) is more than (V1-V7, delivery pressure of the single-stage air compressor will increase and the effective swept volume will reduce.
If the delivery pressure is further increase, the delivery pressure reaches P8, and the compression follows the curve 1-8, where there will be no delivery of compressed air. Thus when the delivery pressure of a single-stage compressor is increased, the mass flow rate also
