An air compressor is a device that converts power (utilizing an electric engine, diesel or gasoline engine, etc.) in to potential energy stored in pressurized air (i.e., compressed air). By one of numerous methods, an air compressor forces increasingly air into a storage tank, enhancing the pressure. When tank tension hits its higher limit the air compressor turns off. The compressed air, after that, is held in the tank til called in to use. The power contained in the compressed air can be used for a selection of applications, using the kinetic energy of the air as it is released and the tank depressurizes. When tank pressure hits its lower limit, the air compressor turns on once again and re-pressurizes the tank.

Compressors use a pressure switch to stop the motor when tank pressure reaches a preset limit-- about 125 psi for many single-stage models. The air line will include a regulator that you set to match the pressure requirements of the tool you're using. The pressure switch may also incorporate an unloader valve that reduces tank pressure when the compressor is turned off. You can pick from either a mobile or a stationary air compressor. And while there are compressors that use rotating impellers to produce air pressure, positive-displacement compressors are more common and consist of the models used by house owners, woodworkers, mechanics and contractors. Here, air pressure is enhanced by reducing the size of the space that contains the air. Most of the compressors you'll run across accomplish this job with a reciprocating engine. Typical compressors can be found in 1- or 2-cylinder types to fit the demands of the tools they power. On the homeowner/contractor level, the majority of the 2-cylinder models operate much like single-cylinder versions, apart from that there are http://bit.ly/1V1zrU9 per revolution rather than one. A few commercial 2-cylinder compressors are 2-stage compressors-- one engine pumps air into a second cylinder that further enhances pressure. On top of the cylinder, you'll find a valve head that secures the inlet and discharge valves. Each are simply thin steel flaps-- one mounted beneath and one mounted at the top of the valve plate. As the piston goes down, a vacuum is created above it. This allows outside air at air pressure to push open the inlet valve and fill up the area above the engine. As the piston goes up, the air above it compresses, holds the inlet valve shut and pushes the discharge valve open. The air moves from the discharge port to the tank. With each stroke, even more air goes into the tank and the pressure rises. Just like a little internal combustion motor, a conventional engine compressor has a crankshaft, a connecting rod and piston, a cylinder and a valve head. The crankshaft is driven by either an electric engine or a gas engine. While there are small designs that are consisted of just the pump and motor, the majority of compressors have an air tank to hold a quantity of air within a preset pressure range. The compressed air in the tank drives the air tools, and the motor moves off and on to automatically keep pressure in the tank.
