Air quality is influencing service life of pneumatic valve is a very important factor.
So the air quality is very important, so, what are the influencing factors on the quality of the air?
And how to improve the quality of air source so as to ensure the good running of pneumatic valves?
Then answer one by one to you.
The main factors affecting air quality: not installed air filter before, cylinder, the impurities in the pipe into the cylinder, the wear of cylinder piston seal ring.
Before long, air filter cleaning and cylinder.
, pneumatic valve positioner before installation of the filter is too coarse.
Improve methods: gas source treatment level, use belt mesh filter, cleaning when you just need to wash the filter removed.
Set up oil free compressor, instrument air supply shall be separately.
And with low gas consumption products.
Pneumatic valves of different gas consumption products varies widely.
Small compressor can not only small gas consumption, air flow rate is low, the electromagnetic valve vent noise is small.
Pneumatic valve and hydraulic valve seals are basically soft material such as plastic, rubber and metal hard material made of, and cooperate in general are cone sealing surface contact.
This structure combination, make its if used in the valve opening and closing more frequently, medium containing hard and soft particle medium, makes the sealing face of the valve seat and valve plate appear relatively easy deformation, especially for soft materials, the probability of its deformation more faster, and eventually lead to seal failure so that the valve leakage.
