Hydraulic o - ringHydraulic o - ring application and use of know - how

Hydraulic O-ring is mainly used for static seal and reciprocating seal, hydraulic O-ring is widely used in daily life, reliable sealing, small leakage, running stability, long life and other advantages are widely used in the industry with the pharmaceutical industry seals , Seals for the nuclear power industry, seals for the natural petrochemical industry, seals for the aerospace industry, etc. Rotating fluid machinery in the field of hydraulic O-rings, which include a floating seal ring and an auxiliary hydraulic O-ring are sealed system squadrons End hydraulic O-ring side of the most important features of one of the components. In the auxiliary hydraulic O-ring for compensating movement, the hydraulic O-ring's own elastic deformation, the rubber seal ring and the contact seal can occur relatively static, non-continuous slip (partial slip) and complete Slip and other complex state of micro-motion, which is the o-type rubber seal of the fretting characteristics. The choice of hydraulic O-ring material is essential, the general flexibility of the seal material can only meet the hardness of static use, and in this high-temperature conditions of frequent movement, we must choose high temperature, wear resistance, anti-aging sealing material.

Avoid using old seals. When using the new sealing ring, also carefully check the surface quality, to determine no holes, protrusions, cracks and grooves and other defects and have enough flexibility before use. Installation, should first strictly open all parts of the hydraulic system, the best use of special tools to prevent sharp edges of the metal will scratch your fingers. Replace the ring, it is necessary to strictly check the seal groove, remove dirt, grinding groove bottom.

Hydraulic O-rings and other rubber products after processing and vulcanization is easy to produce dimensional changes, which may be due to such as molding shrinkage or extrusion expansion relaxation caused by various factors, these changes in the design and manufacture of a product mold and mouth Type such components should be identified and considered.

Hydraulic O-ring storage room temperature is preferably below 30 ?, to avoid high-temperature aging of the seal; must be stored in a sealed package to avoid moisture and dust in the air contact; must avoid strong light to avoid the seal air In the ozone erosion or premature aging.

Hydraulic O-rings are used where required in the final application and should be limited to those dimensions that are considered critical. The higher the precision used, the more stringent the control that must be performed in the manufacturing process, and therefore the higher the cost . application and use of know - how
