air filterworking principle
In pneumatic technology, air filter, pressure reducing valve and oil mist device are called the three major pneumatic components. In order to obtain multiple functions, these three air source treatment elements are often assembled together in order, which is called a pneumatic triplet. Used for air source purification, filtration, decompression and lubrication.
The installation sequence of the three major components is air filter, pressure reducing valve, and oil mist device according to the intake direction. The three major parts are indispensable air source devices in most pneumatic systems. They are installed near the air-using equipment and guarantee the quality of compressed air. In addition to ensuring the quality of the three major parts, they must also consider saving space, Convenient operation and installation, can be combined arbitrarily and other factors. The compressed air flowing in from the inlet is introduced into the baffle. The baffle has evenly distributed helical teeth similar to fan blades, forcing the compressed air flowing at high speed to produce strong rotation along the tangent direction of the teeth, which is mixed in the air. Liquid water, oil and larger impurities are separated under the action of strong centrifugal force, thrown on the inner wall of the water cup, and flow to the bottom of the water cup. The compressed air, which removes liquid water, oil and larger impurities, is further filtered by the filter element to remove tiny solid particles, and then clean compressed air is output from the outlet. Umbrella-shaped water baffle ⑸ separates the water cup into upper and lower parts, and the lower part maintains a static pressure zone, which can prevent the high-speed rotating airflow from sucking up the water and oil at the bottom of the cup. The water and oil collected at the bottom of the cup are discharged from the drain valve, and the air filter must be installed vertically with the cup downward.
