Compressed air is used in many operations and processes and as a source of energy for heating, ventilating, and air conditioning (HVAC) and process actuators and motors. It may also be supplied for low pressure systems and used for pneumatic control. Air can be compressed in several different ways and supplied at varying pressures and degrees of filtration depending on its use. Check out the list we’ve compiled for you below from Aroundclock.com.
A typical compressed air system is capable of producing instrument quality air for pneumatic HVAC controls, tools, conveying systems, and general plant air. The system consists of a single motor driven single stage rotary screw compressor with inlet air filter, a safety relief valve, aftercooler, air/oil separator, air receiver with safety relief valve, prefilter, air dryer, afterfilter, oil/water traps, and oil/water separator.
Compressors are most often supplied skid mounted as a packaged unit.Theassembled package includes all major components, controls, and a sound attenuation enclosure. The unit only requires mounting to a foundation,hook up to system piping, connection to the oil water separator, and power connection.
There are various types of compressors: Rotary helical screw air compressors are positive displacement machines. Atwin-screw compressor consists of accurately matched rotors [one lobe (male) and one helix (female)] that mesh closely when rotating within a close tolerance common housing. One rotor is motor driven while the other is gear driven, turning it in a counter-rotating motion.
The rotors uncover inlet posts at one end allowing air to flow in. As the rotors continue to rotate the air is compressed by the minishing volume between the rotors . At the end of the rotors, ports allow the now compressed air to exit. One or more stages may be used.
These compressors are used in … Read more...
