DESIGN AND FABRICATION OF MULTI ENGINE AIR COMPRESSOR

Abstract

A compressor is used to get high pressure air for many industrial and commercial purpose.  The triangular air compressor with the common compression chamber is a reciprocating type compressor, which delivers air at high pressure with less vibration and less power consumption than the existing ones.  Triangular air compressor with common compression chamber uses three cylinders and the entire cylinder and all the cylinders will have their own connecting red, crank shaft, pistons and chain sprockets and it is driven by a chain drive. During operation the pistons will move in phase from BDC to TDC and hence the air is compressed in the common compression head.  This common in the compression chamber will have one inlet and outlet valve.  From this valve, air is intake and delivered.  The common compression head will be is a triangular shape with angle of 60* from one side to another. The compressor is mechanical equipment which is used to increase the pressure with the help of the piston. Need to improve the performance of compressor by several methods. The main aim of the project is to make tri-cylinder, air compressor to generate large amounts of air with less power and low vibration. In Tri cylinder, air compressor the three cylinders are kept at 120 degrees to each other. The three cylinders are placed radically and equally apart such that the cylinder opening tends to meet on a common triangular compression chamber. The three pistons are made to compress air simultaneously onto the common triangular chamber over shorter stroke and the isothermal efficiency will be better than single cylinder with one piston. The motor is connected to the chain drive to drive the three crankshafts which are used to move the piston. If space is smaller the pressure will be more and bigger lower. If compressor is made to work at 1400 rpm air taken will be147.18 × 1400 = 206052 litters at 7 atmospheres pressure .The advantage with triangular compressor will be low vibration, smaller unit giving more output and so cheaper to make, ideal for air compressor is Airconditioning and Refrigeration, Vacuum pumps and general purpose usage.
