Tree type air compressor

Main Articles Tree type air compressor

the Three main types of air compressors reciprocating rotary screw centrifugal These types optionally be specified using: the Number of compression stages cooling Method (air, water, oil) Method of the drive (motor, engine, steam, other) lubrication (oil, oil-Free, where Free does not mean that the lubricating oil contacts the compressed air) packaged or custom Piston air compressors, Piston air compressors positive machine offset, this means that they increase the pressure of the air by reducing its volume. This means that they take in the successive volumes of air which is confined in the closed space and lifting the air to a higher pressure.TheПоршневого air compressor reaches this, the piston in the cylinder, and compressing and displacing element. Single-stage and two-stage reciprocating compressors are commercially available. Single-stage compressors are generally used for pressures in the range of 70 pounds per square inch to 100 pounds per square inch. Two-stage compressors are generally used for higher pressures in the range of from 100 psig to 250 psig. note that 1 HP ~ 4 CFM at 100 psi and that from 1 to 50, as a rule, HP reciprocating devices. The compressor 100 HP and above, as a rule, Screw or centrifugal compressors. TheПоршневого air compressor unilateral action, когдаthe compression is carried out using only one side of the piston. The compressor using both sides of the piston is double-acting. The load reduction is achieved unloading of the individual cylinders. This is usually accomplished by throttling the suction pressure in the cylinder or bypassing the air inside or outside of the compressor. Capacity control is achieved by changing the speed in the motor units by controlling fuel consumption. Reciprocating air compressors are produced in air cooled or water cooled in lubricated and non-lubricated configurations and provide a wide range of selection pressure and performance. Screw compressors Rotary compressors are volumetric compressors. The most common compressor rotor воздухthe single-stage helical or spiral the share of oil flooded screw compressor. These compressors consist of two rotors within the casing, where the rotors to compress the air inside. There are no valves. These devices are mainly oil-cooled (air-cooled or water-cooled oil coolers), where the glands of internal clearances. Since the cooling takes place right inside the compressor, the working parts never experience extreme operating temperatures.TheРоторный the compressor, therefore, is a continuous duty, air cooled or water cooled compressor package.

Rotary screw compressors are easy to maintain and operate. Regulation performance for these compressors is a variable speed and variable volume compressor. For the latest management techniques,a spool accommodated in the housing. As the capacity of the compressor decreases, the spool opens the valve, bypassing part of the compressed air back to the suction. The advantages of rotary screw compressor includes a smooth, pulsation of the output air in a compact size with a large amount of output for a long life.

Oil free air Compressor utilizes a specially designed air ends for compressing air without oil in the compression chamber yielding true oil free air. Oil free screw air compressors are available with air-cooled and water-cooled to provide the same flexibility as oil flooded the rotors when you need oil free air.

Centrifugal compressor is a dynamic compressor, which depends on transfer of energy from a rotating impeller to the air.

Centrifugal compressors produce reset high pressure by converting the angular momentum transferred by the rotating impeller (dynamic movement). In order to do this effectively, centrifugal compressors rotate at higher speeds than other types of compressors. These types of compressors are also designed for higher power, because the flow through the compressor continuously.

the adjustment of the inlet guide vane is the most common method of power control in a centrifugal compressor. When closing the guide vanes, the volumetric flows and ability are reduced.

Centrifugal compressor Vozduha oil free compressor in accordance with the project. Oil lubrication Undercarriage is separated from air by the shaft seal and the atmospheric holes.
