Pneumatic valve maintenance small coup

maintenance method, pneumatic valve should be placed in ventilated and dry inside the chamber of secrets, pneumatic valves at both ends of the channel is obstructed.
, if the storage time is long, and should be inspected periodically and regular cleaning and after cleaning to besmear antirust oil.
and after the installation, we must also periodically check the pneumatic valve and aging degree of normal work. Main projects include:
( Sealing surface wear.
( Pneumatic valve stem and abrasion of trapezoidal thread of pneumatic stem nut.
( Packing is outdated failure, if any, should be replaced in a timely manner.
( Pneumatic valve repair after assembly, should carry on the sealing performance test.
pneumatic valves also regularly to inject grease inside, can use for longer periods of time, the right and orderly maintenance and maintenance of the pneumatic valve, pneumatic valve can make the function of normal and can increase the service life, some things tend to ignore.
the first, at the time of injection oil, tend to ignore the quality of the oil, oil quality is very important, some grease of pneumatic valve not only failed to protect, might also have side effects, so in choosing a grease, try to choose better grease. With pneumatic valves, if less injection, sealing surface due to the lack of lubricant and speed up the wear and tear. Inject more fat, can cause pneumatic valve jam, affect the normal work, but also can cause the waste oil, when to inject grease pneumatic valves, pneumatic valves should be according to the different size and specification for injection, can according to the size of the pneumatic valve size capacity, calculated, then the proper injection.
the second injection, in the pneumatic valve oil, often ignore the problem of pressure. When the injection pressure is too low, can lead to seal failure, or pressure is too high, note oil mouth can easily plug.
