<> Taiwan DPC compressed air compressed air system is usually composed of the following three parts:
1. Air pressure generating device.
Including air compressors, ventilators and their drives, control devices, local and interstage cooling devices, waste heat ** equipment and suction filters, air storage tanks, etc.
2. Compressed air treatment system.
In order for the output pressurized humidity air to meet the quality requirements of the pneumatic system, the compressed air (coarse gas) discharged from the air compressor needs to be post-treated. The aftertreatment unit includes a gas (oil) water separator, a filter and a dryer.
3. Compressed air distribution system.
This includes gas collectors, branch networks, and valves. Depending on the requirements, it also includes water collection drains, functional filters and other auxiliary treatment devices in the network.
Compressed air is the second largest power energy source after electricity, and it is a process gas source with a variety of purposes, and its application range covers petroleum, chemical industry, metallurgy, electric power, machinery, light industry, textile, automobile manufacturing, electronics, food, medicine, biochemistry, national defense, scientific research and other industries and departments.
The main function of the compressed air system is to provide a power source for production, and the main role of the compressed air system in the production and manufacturing is to provide the power of the pneumatic control valve and the pneumatic shut-off valve.

Glad to answer for you :
The quality standard of compressed air for pneumatic system can refer to the specification JB T 5967-2007 "Quality Grade of Air Medium for Pneumatic Components and Systems", in which the grade division is divided by referring to the standard GB T compressed air.
Most pneumatic systems do not have high requirements for the quality of compressed air, but the requirements for pneumatic compressed air quality for food and beverage processing, painting, photographic film manufacturing systems and not mentioned in Table 5 for pharmaceutical, medical, electronic and other systems are very high, and the requirements for air source systems are also increased.
For the air source system, it is generally composed of an air compressor, an air storage tank, a compressed air purification system, a pipeline system, etc., of which the compressed air purification system is configured in combination with the user's quality requirements for compressed air, and there are conventional devices for removing oil, water, dust (particulate matter) and sterilization. At present, there are many ways to remove water, particulate matter and fungal pollutants on the market, and they are relatively effective, while the treatment of oil pollutants has always been a troublesome problem. Although the activated carbon adsorption method can achieve deep purification, because the adsorption of oil pollutants is a cumulative process, it is easy to achieve adsorption saturation and reduce the purification effect. At present, the catalytic oxidation combustion degreasing method on the market can completely remove oil pollutants in principleHowever, it is still necessary to do practical consultation or test verification for the performance of the actual product.

(1) Compressed air should have a certain pressure and sufficient flow.
2) The compressed air should have a certain degree of cleanliness and dryness.
Therefore, the air source device in the pneumatic system must be provided with some auxiliary equipment for degreasing, water removal, dust removal, and drying the compressed air, improving the compressed air quality, and carrying out air source purification treatment.

The compressed air system is mainly composed of air compressor, air storage tank, dryer, DPC compressed air filter, gas pipeline, valve, cooler and so on. The production process of compressed air mainly includes air filtration, air compression, air cooling, oil and moisture removal, air storage and rain transportation.
Air compressor: In general compressed air stations, the most widely used is piston air compressor; Centrifugal or axial air compressors are more commonly used in large compressed air stations.
Air storage tank: its function is to weaken the air flow pulsation discharged by the piston air compressor, improve the continuity and pressure stability of the output air flow, further precipitate and separate the water and oil in the compressed air, and ensure the continuous supply of sufficient air volume. The gas storage tank is divided into two types: discrete and horizontal, usually the vertical type is used more, its height is 2 3 times the diameter, and the volume is about the volume of the compressor per minute production capacity converted into compressed gas.
Compressed air dryer: At present, the most commonly used compressed air drying methods are adsorption method and freezing method, and the most common compressed air dryers are adsorption dryers and refrigeration dryers.
Compressed air filter: there are five types of coarse filter, medium filter, high and medium efficiency filter, sub-high efficiency and high efficiency filter, each model has different standards and use efficiency.
Aftercooler: After the air is compressed by the compressor, its exhaust temperature can reach 140 170, and the aftercooler installed after the compressor can reduce the temperature of the compressed air, which is conducive to the separation and removal of oil and moisture contained in the compressed air. Commonly used aftercoolers include tubular type, heat sink type, casing type, etc.

The compressed air system consists of an air compressor, an air tank, a dryer and a filter.
-
A typical pneumatic system consists of the following components:
Air compressor + aftercooler + gas tank + main filter + dryer + triplet + control valve + speed control valve + actuator.
Air compressor: the power source of the pneumatic system.
Aftercooler: Lowers the temperature of the compressed air produced by the air compressor.
Gas tank: voltage stabilization, energy storage.
Main filter: Filters impurities from compressed air.
Dryer: Remove water from compressed air.
Triple parts: further filtration and impurity removal, pressure adjustment at the use end, oil lubrication (not used in oil-free lubrication system).
Control valve: Directional control of compressed air.
Speed control valve: speed control of compressed air.
Actuator: Outputs pressure into mechanical action.

The air source heat pump unit is composed of a compressor, a fin heat exchanger, a shell and tube heat exchanger, a throttle valve and a controller.
The compressor is the heart, the fin heat exchanger is the lungs of the air conditioner, the passenger tube heat exchanger is connected with the water to transport cold or hot water, and the controller controls the compressor and water temperature.
There is an air source heat pump that is a wind and snow heat pump, focusing on the fin heat exchanger (lung heat exchange) system, which optimizes the operating environment of the unit and improves the energy efficiency of the unit.
Compressed air is very versatile.
Pumping compressed air into the tires of cars and bicycles not only supports the weight of the car body and all objects on the car, but also makes the driver and cyclist feel stable and comfortable. Cars, walls and furniture can be painted with paint mixed with compressed air in cans. Spraying unclean masonry buildings with compressed air can wipe off the dirt on the surface of the masonry. >>>More

Of course, nitrogen.
The oxygen in the air has an oxidizing effect on the tire, and the use of nitrogen will prolong the service life of the tire, especially in the summer when the temperature is high and when running at high speeds. >>>More
