WHAT IS THE WORKING PRINCIPLE OF A RECIPROCATING OR PISTON AIR COMPRESSOR?
The reciprocating or piston compressor consists of a piston, inter-outlet valves, and cylinder with an adequate cooling arrangement, connecting rod, and crank. The working is the same as the compression stroke of two-stroke engines. A single-stage reciprocating air compressor is an air compressor that carries out compression in a single stroke & a two-stage reciprocating air compressor is an air compressor that carries out compression in two strokes and consists of two cylinders.
The basic working principle of a reciprocating air compressor or a piston air compressor is to use pistons driven by a crankshaft to move air at high pressure. The first step in this process is that the piston in the reciprocating compressor moves back and forth in the cylinder by a rotating shaft, known as a crankshaft, using a connecting rod that converts rotary motion to reciprocating action. Either engine or an electrical motor provides the power to rotate the crankshaft. The cylinder is supplied with suction and discharge valves. A suction valve is the one that admits air into the cylinder, and delivery lets out the air once it is compressed. The valves must open and close in a coordinated manner to produce compressed air.
