Air Compressor Compressed gas volume

Compressed air as a dynamic energy consumption of products, the scope of its application and the industry is very extensive, compressed air as an important source of industrial products, energy can be called industrial production of "life gas".

Compressor is a kind of compressed gas volume and improve the gas pressure and the transmission of gas machinery and equipment, can reduce the volume of gas, the pressure increases, with a certain kinetic energy, can be used as mechanical power or other purposes.

Compressed air can be divided into air compressors, oxygen compressors, ammonia compressors, natural gas compressors and so on.

According to the installation of the project category is divided into: piston compressor, rotary screw compressor, centrifugal compressor (motor drive) and so on.

According to the compressor gas can be divided into: positive displacement compressors and power compressors two categories. According to the structure type and working principle, the positive displacement compressor can be divided into reciprocating (piston type, membrane type) compressor and rotary (vane type, screw type, rotor type) compressor; dynamic compressor can be divided into shaft Flow compressors, centrifugal compressors and Francis compressors.

According to the number of times can be divided into compression: single-stage compressor, two-stage compressor, multi-stage compressor.

According to the arrangement of the cylinder can be divided into: vertical compressors, horizontal compressors, L-type compressors, V-type compressors, W-type compressors, fan-shaped compressors, M-type compressors, H-type compressors.

According to the arrangement of the cylinder can be divided into: series compressor, parallel compressor, double compressor, symmetrical balanced compressor - cylinder lying in the crankshaft journal 180 ° crankshaft on both sides, arranged in H Type, type D, M type, the inertial force of the basic balance (large compressors are moving in this direction).

According to the compressor exhaust final pressure division, can be divided into: low pressure compressor - exhaust pressure in the 0.3 ~ 1.0MPa; medium pressure compressor - exhaust pressure in the 1.0 ~ 10.0MPa; high pressure compressor - exhaust Pressure in the 10.0 ~ 100.0MPa; ultra-high pressure compressor - exhaust pressure above 100.0MPa.

According to the size of the compressor displacement, can be divided into: micro-compressor - gas transmission in the 1m3 / min below; small compressor - gas transmission in the 1 ~ 10m3 / min; medium compressor - gas The amount of 10 ~ 100m3 / min; large compressor - gas transmission in the 100m3 / min or more;

According to the lubrication method can be divided into: oil-free compressor, oil lubrication compressor.

According to the cooling method can be divided into: water-cooled compressor, air-cooled compressor.

According to the type of transmission, can be divided into: motor-driven compressors, steam-powered compressors, internal combustion engine-driven compressors, steam-powered compressors.

According to the power machine and compressor transmission method can be divided into: rigid coupling direct drive compressor, flexible coupling direct drive compressor, reduction gear drive compressor, belt drive compressor, no crankshaft - connecting rod The mechanism of the free piston compressor.

Compressor performance parameters include volume, flow, suction pressure, exhaust pressure, efficiency, input power, output power, performance coefficient, noise and so on.

The following is the analysis of the use of compressed air in various industries:

1. inflatable inflatable: tire filling, blow molding, blowing, blowing, food filling and so on.

2. Control instrumentation: machining center, machine tool, printing machinery, auxiliary equipment control of power plant, train brake, rail changing device, vehicle doors and windows opening and closing, control valves, instrument power and so on.
