1. What is Keaser Air Compressor and It's Types Keaser Air Compressor is a machine that increases the pressure of air. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids. The main types of air compressors are: Reciprocating - uses pistons driven by a crankshaft to draw in air and compress it. Rotary screw - uses two meshing helical screws to force the gas into a smaller space. Centrifugal - uses a rapidly rotating impeller to draw in air and compress it. Axial - uses a series of blades mounted on a shaft to draw the air into the compressor and compress it. How Air Compressors Work All air compressors work on the same principle: they take in air at atmospheric pressure and compress it to a higher pressure. The main difference between the different types of compressors is how they compress the air. Reciprocating Compressors Reciprocating compressors use pistons driven by a crankshaft to draw in air and compress it. The pistons are connected to the crankshaft by rods and move up and down in cylinders. The air is drawn into the cylinders through intake valves and compressed by the pistons as they move up. The compressed air is then discharged through discharge valves. Rotary Screw Compressors Rotary screw compressors use two meshing helical screws to force the gas into a smaller space. The screws are driven by a motor and rotate at high speeds. The air is drawn into the compressor through intake ports and forced between the screws. The screws compress the air as they mesh together and force it into a smaller space. The compressed air is then discharged through discharge ports. Centrifugal Compressors Centrifugal compressors use a rapidly rotating impeller to draw in air and compress it. The air is drawn into the center of the impeller and forced outwards by the centrifugal force. The air is then compressed by the vanes of the impeller as it is forced outwards. The compressed air is then discharged through an outlet. Axial Compressors Axial compressors use a series of blades mounted on a shaft to draw the air into the compressor and compress it. The air is drawn in through intake ports and forced through the blades of the compressor. The blades compress the air as it is forced through them and discharge it through discharge ports.
