Hydraulic seals material with hydraulic oil (liquid) compatibility
Nitrile rubber hydraulic seals suitable for petroleum-based hydraulic oil, glycol-based hydraulic oil, diester Department of lubricating oil, gasoline, water, silicone grease, silicone and other media use. Nitrile rubber hydraulic seal is currently the most widely used and lowest cost rubber seals. Does not apply to polar solvents being, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. General temperature range of -40 ~ 120 ?. From material to material, the use of static pressure is less than 20Mpa. Sometimes for dynamic, dynamic pressure is smaller than 5Mpa, semiconductor and vacuum sealing. Alternative sizes are: cross-sectional diameter of about 0.35 ~ 12mm inner diameter up to 1000mm and above [View Details]
Xu Xinhua commentary material
??Xinhua Xu Hydraulic O-ring material commonly used hydrogenated nitrile rubber HNBR ??Xinhua Xu hydrogenated nitrile rubber (Hydrogenate Nitrile) nitrile rubber by removing part of the double-stranded after hydrogenation, after hydrogenation of their heat resistance, weather resistance than nitrile rubber to improve a lot, oil and general NBR similar. General temperature range of -25 ~ 150 ?. ??Advantages: [View Details]
Xinhua Xu rubber O-ring tips
Prevent the formation of seal damage when the device is a rubber O-ring seal in addition to an appropriate finish, secure chamfering, remove burrs, and the right thing, in the way the device how to prevent dust drift falling rubber O-ring appearance; to cleaning hydraulic medium rubber o-rings.

Influence of temperature on the small hydraulic seal reliability
Typically, hydraulic seals made of a polymer material such as rubber, whose design and analysis relates to solid mechanics, tribology, polymer materials, thermodynamics and mechanical manufacturing process and other aspects of the theory of knowledge, generally using finite element software for hydraulic seals Analyse. Hydraulic seal is compressed by the occurrence of large deformation, resulting in stress to achieve the seal of the hydraulic system. To meet the hydraulic seal sealing performance, must be guaranteed to meet the premise of the hydraulic seal shear strength, the maximum contact stress must be at least sealing medium pressure. Many factors influence the hydraulic seal of stress, including the sealing structure parameters such as the compression ratio, the structure size parameters, the contact [View Details]
Use large size of the rubber O-ring to pay attention to those details
Use large size of the rubber O-ring to pay attention to the following technical details ??(1) large-sized rubber O-ring to calculate the pre-stretch ratio (piston seal) or pre-compression ratio (rod seal), reduction of area; ??(2) Further note that large-sized rubber O-ring sealed and liquid compatibility, taking into account the seal swelling; ??(3) also consider the thermal expansion of large-sized rubber O-ring. ??Such as piston seal: seal groove diameter is at 780, then you order a large-sized [View Details]

Figuring Hydraulic O-ring
First, how to identify the specific material of rubber products ??Our production of hydraulic O-rings have a variety of materials, Dingqing hydraulic O-ring, fluorine rubber O-ring hydraulic, silicone O-rings, hydraulic EPDM O-rings, hydraulic neoprene O-rings, etc. identification: ??1, anti-media experiment weight gain [View Details]
Hydraulic seal lasting deformation how to do?
Because the use of hydraulic seal consisting of elastic rubber materials attributed to data, the initial planning of the compression and rebound blocked amount to the long-term use, decreased flexibility, lasting deformation occurs, resulting in seal decline, after the onset of the leak.
