Pneumatic valve small daily maintenance guide

pneumatic valve range widely used in various fields, and not only and using the environment is also different, some under bad working conditions of pneumatic valve is prone to problems. The pneumatic valve is an important equipment, especially for some large pneumatic valves, once appear, is quite troublesome problem needs to be repaired or replaced. So do daily maintenance and maintenance is particularly important. Let's learn about the knowledge of a little of pneumatic valve maintenance.
a deposit, pneumatic valve and daily check
should be save dry ventilated room, pneumatic valve, on both ends of the channel must be blocked.
and long-term storage of pneumatic valve should be checked regularly, remove dirt, and rust-proof oil coating on the surface of the processing.
, after installation, should check regularly, main inspection items:
( 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( Packing is outdated failure, if any, should be replaced in a timely manner.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.
2, pneumatic valve on the maintenance of the
before welding production before and after production of the professional maintenance of pneumatic valve, pneumatic valves for serving the production operation plays a vital role, orderly and effective maintenance will protect right pneumatic valve, pneumatic valve to function properly, and prolong the service life of pneumatic valve. Pneumatic valve maintenance looks be like simple, actually otherwise. Work often have neglected aspect.
the first note fat, pneumatic valve, note the amount of fat often ignore. Note grease gun after lubrication, operators choose pneumatic valves and greasing connection, on the operations. There are two kinds of circumstances: on the one hand, on the quantity is little greasing, sealing surface due to the lack of lubricant and speed up the wear and tear. On the other hand on the excessive, resulting in waste. Is no categories depending on the type of pneumatic valve, pneumatic valve sealing capacity of different calculations. In pneumatic valve size and class, calculate the sealing capacity and reasonable injection amount of grease.
the second note fat, pneumatic valve, often ignore the pressure problem. In the greasing operation, on the pressure changes regularly with peak valley. Pressure is too low, high pressure seal leakage or failure, on the mouth blockage, sealed inside lipid hardening or seal and pneumatic ball valve, pneumatic valve plate lock. Usually fat injection pressure too low, injecting grease into the pneumatic valve at the bottom of the cavity, more commonly occur in small brake pneumatic valve. And fat injection pressure is too high, on the one hand, to check on the mouth, so fat pore blocking determine to change the situation; Is lipid hardening on the other hand, to use cleaning fluids, repeated failure sealing grease of softening, and inject new replacement grease. In addition, sealing type and sealing material, also influence on the pressure, different seal forms have different fat injection pressure, usually hard seal fat injection pressure is higher than the soft seal.
do a good job in these believe to extend the service life of pneumatic valve is helpful, but also can reduce a lot of unnecessary trouble.
