Hydraulic O-rings prevent leakage and corrosion
Hydraulic O type external sphere of influence factors include the characteristic parameters of the sealing gap, manufacturing precision, surface properties, the reciprocating motion distance and frequency, special l raw hydraulic O-ring and the pressure medium and means, such as pressure, speed, work time, stop time and temperature and so on.
Hydraulic O-ring surface uniform corrosion, if the metal ring surface contact with the corrosive medium, the metal itself and impatience corrosion, will produce surface corrosion, which is the phenomenon of leakage, early wear, damage, sound and so on. Selection and surfacing of cast iron carbide, tungsten carbide, titanium and other sealing ring, prone to stress corrosion cracking;
Mechanical seal stress corrosion cracking of metal under the simultaneous action of corrosion and tensile stress, abrasion resistance.
O-rings to prevent leakage of hydraulic methods are:
(1) Hydraulic O-ring seal Seals gap surface;
(2) Hydraulic O-ring seals off the leakage path;
(3) Hydraulic O-ring seal leakage path increases the resistance;
(4) Hydraulic O-ring to seal leak caused by media pressure to counteract or balance the pressure difference between the leakage path.
