Air Compressor Parts

Air compressor parts refer to the various parts that make-up an air compressor. An air compressor is a device which is known to convert power, normally from an electric motor, a gasoline engine or a diesel engine, into kinetic energy by pressurizing and compressing air which is able to be released with quick bursts upon command. One type of air compressor is a lung compressor. For example, when a person takes a deep breath to blow out a candle, he or she is increasing the air pressure in their lungs which in turn becomes air compressors containing pressurized air.

There are generally two types of man made air compressors: dynamic and positive displacement and each is defined as by their mode of operation. The positive air compressor operates by filling and then emptying an air chamber. A dynamic air compressor on the other hand utilizes a rotating device to accelerate and decelerate air. This process increases the air’s pressure by using the velocity or speed of the air. Centrifugal air compressors are dynamic air compressors.

There exists many different types of air compressors and many of the air compressor parts are not the same as they differ according to the type of compressor that is in question. Some parts are common to all compressors such as the pressure gauge and reserve tank. Common compressor types like cooling fans, exhaust vents and pressure relief valves are present in most types of air compressors.

While the basic operations of air compressors is the same, some machines use rings and pistons which are mounted on a crankshaft with connecting rods designed to pump the air, while other compressors utilize a screw-type compressing unit along with an impeller. These three types of compressors are most common: Screw-type, reciprocating and rotatory. Between these three, the reciprocating compressor is the most commonly used compressor. The design works similarly to an automobile engine. The piston is armed with piston rings and moves down and up the cylinder by connecting a rod that is attached to a crankshaft. The bearings sandwiched between the crankshaft and rod allows the air compressor parts to work correctly for years without fail. The piston rings give a seal located between the cylinder wall and piston in order to allow the piston to force air or pump into the holding tank.

Special compressor parts that come in the form of spring-loaded valves operate by suction to allow the piston to draw air to the cylinder on the stroke down of the piston. Once the piston begins its upward journey in the cylinder, the intake valve is closed with a push and the exhaust valve ends up being pushed open. The air is pushed through the now-opened exhaust valve by the piston while it goes up the cylinder and makes its way out of the cylinder and into the holding tank. Once every bit of air is removed out of the cylinder, the spring-loaded valve closes which prevents the air from escaping into the holding tank.

This basic operational cycle is rehashed in all forms of compressors albeit using a variety of air compressor parts for compressing and pumping methods. The screw-type compressor utilizes two screw assemblies which are inter-meshing that capture air between screw-type compressor parts and move it into the holding tank. This screw-type compressor type utilizes the steady flow of air through the screw to hold air in the tank whilst the compressor is running. The rotary type of air compressor uses a round drum which spins off center in order to trap air and force it through special valves and right into the holding tank.
