The introduction of air source treatment components

Air source treatment is the component working by using  the pressure of the gas or the expansion of the force.  It Includs air filter, pressure regulating valve, oil lubricator, etc.  Pneumatic products are widely used in metallurgical mechanical and electrical, construction, transportation equipment, home appliances, light industry, machine tools, medical, packaging industry and other industries automation production.  However, because the compressed air can not be directly used t, it contains a certain amount of moisture, oil and dust. After compression, the air temperature is as high as 140-170℃, and some of the water and oil have become gaseous.  Therefore, it is necessary to use the compressed air after purification treatment to run the mechanical equipment.  

The air source treatment includes air filter, pressure reducing valve and oil lubricator. Some companies’ solenoid valve and cylinder can do oil-free lubrication (lubricating air by grease), which does not need to use oil mist device.  The filtration degree is generally 50-75μm, the pressure regulating range is 0.5-10MPa, if the filtration accuracy is 5-10μm, 10-20μm, 25-40μm, and the pressure regulating is 0.05-0.3Mpa, 0.05-1Mpa three large pieces of no pipe connected components called three coupling.  The three components are indispensable air source devices in most pneumatic systems. They are installed near the gas equipment and are the final guarantee of compressed air quality.  The installation sequence of the three pieces is air filter, pressure reducing valve and oil mist device according to the inlet direction.  The combination of air filter and pressure reducing valve are called pneumatic coupling.  We can also set air filter and pressure reducing valve together, it becomes a filter regulator (function and air filter and pressure reducing valve combined with the use of the same). Oil mist in the compressed air is not allowed in some occasions. It is necessary to use the oil mist separator to filter out the oil mist in the compressed air.  In summary, these components can be selected as needed, and they can be used in combination.  The air filter is used to clean the air source. It can filter the moisture in the compressed air and avoid the moisture entering the device with the gas.  The pressure reducing valve can stabilize the pressure of the air source, so that the air source is in a constant state, and the damage to the hardware such as the valve or actuator can be reduced due to the sudden change in the air pressure of the air source.  The filter is used to clean the air source. It can filter the water in the compressed air and avoid the water entering the device with the gas.  The oil mist can lubricate the moving parts of the machine body, and can lubricate the parts that are not convenient to add lubricating oil, thus greatly prolonging the service life of the machine body.
