2500nm3 / H Reciprocating Oil Free O2 Compressor Discharge Pressure 5 Bar

1.description

A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistonsdriven by a crankshaft to deliver gases at high pressure.The intake gas enters the suction manifold, then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft, and is then discharged. Applications include oil refineries, gas pipelines, chemical plants, natural gas processing plants and refrigeration plants. One specialty application is the blowing of plastic bottles made of polyethylene terephthalate (PET).

In the ionic liquid piston compressor many seals and bearings were removed in the design as the ionic liquid does not mix with the gas. Service life is about 10 times longer than a regular diaphragm compressor with reduced maintenance during use, energy costs are reduced by as much as 20%. The heat exchangers that are used in a normal piston compressor are removed as the heat is removed in the cylinder itself where it is generated. Almost 100% of the energy going into the process is being used with little energy wasted as reject heat.

2.use

Reciprocating compressors use pistons driven by a crankshaft. They can be either stationary or portable, can be single or multi-staged, and can be driven by electric motors or internal combustion engines.Small reciprocating compressors from 5 to 30 horsepower (hp) are commonly seen in automotive applications and are typically for intermittent duty. Larger reciprocating compressors well over 1,000 hp (750 kW) are commonly found in large industrial and petroleum applications. Discharge pressures can range from low pressure to very high pressure (>18000 psi or 180 MPa). In certain applications, such as air compression, multi-stage double-acting compressors are said to be the most efficient compressors available, and are typically larger, and more costly than comparable rotary units. Another type of reciprocating compressor, usually employed in automotive cabin air conditioningsystems,is the swash plate compressor, which uses pistons moved by a swash plate mounted on a shaft (see axial piston pump).

Household, home workshop, and smaller job site compressors are typically reciprocating compressors 1½ hp or less with an attached receiver tank.

3.application

Gas compressors are used in various applications where either higher pressures or lower volumes of gas are needed:

• In pipeline transport of purified natural gas from the production site to the consumer, a compressor is driven by a gas turbine fueled by gas bled from the pipeline. Thus, no external power source is necessary.
• Petroleum refineries, natural gas processing plants, petrochemical and chemical plants, and similar large industrial plants require compressing for intermediate and end-product gases.
• Refrigeration and air conditioner equipment use compressors to move heat in refrigerant cycles (see vapor-compression refrigeration).
• Gas turbine systems compress the intake combustion air.
• Small-volume purified or manufactured gases require compression to fill high pressure cylinders for medical, welding, and other uses.
• Various industrial, manufacturing, and building processes require compressed air to power pneumatic tools.
• In the manufacturing and blow moulding of PET plastic bottles and containers.
• Some aircraft require compressors to maintain cabin pressurization at altitude.
• Some types of jet engines—such as turbojets and turbofans—compress the air required for fuel combustion. The jet engine's turbines power the combustion air compressor.
• In SCUBA diving, hyperbaric oxygen therapy, and other life support devices, compressors put breathing gas into small volume containers, such as diving cylinders.
• In surface supplied diving, an air compressor frequently supplies low pressure air (10 to 20 bar) for breathing.
• Submarines use compressors to store air for later use in displacing water from buoyancy chambers to adjust depth.
• Turbochargers and superchargers are compressors that increase internal combustion engine performance by increasing the mass flow of air inside the cylinder, so the engine can burn more fuel and hence produce more power.
• Rail and heavy road transport vehicles use compressed air to operate rail vehicle or road vehicle brakes—and various other systems (doors, windscreen wipers, engine, gearbox control, etc.).
• Service stations and auto repair shops use compressed air to fill pneumatic tires and power pneumatic tools.
• Fire pistons and heat pumps exist to heat air or other gasses, and compressing the gas is only a means to that end.
• Rotary lobe compressors are often used to provide air in pneumatic conveying lines for powder or solids. Pressure reached can range from 0.5 to 2 bar g.
