Air source knowledge of pneumatic actuator
Pneumatic valve driven by compressed air to enable switching or regulating control, all need air source to drive, the quality of air source directly affects the use of pneumatic valves. A good, stable and high-quality air source can extend the service life of the pneumatic valve, so there are certain requirements for the quality of the air source.
Air quality is a very important factor affecting the service life of pneumatic valves. So the quality of the air source is very important, then, what are the factors that affect the quality of the air source? How to improve the quality of the air supply to ensure the good operation of the pneumatic valve?
Main factors affecting air source quality:
1. The air filter is not installed before the cylinder, causing impurities in the pipeline to enter the cylinder and wear the sealing ring of the cylinder piston.
2, the air filter in front of the cylinder is not cleaned for a long time.
3. The filter installed before the positioner of the pneumatic valve is too thick.
Methods to improve the level of air source treatment:
1, Using air filter , Remove the filter can be cleaned in time .
2, instrument air source should be set up separately oil-free compressor.
3. Use products with low air consumption. The gas consumption of pneumatic valves varies greatly from product to product. Small gas consumption not only the compressor can be small, the air flow rate can be low, the electromagnetic valve exhaust noise is also small.
