Hydraulic silicone rubber O-ring PRECAUTIONS parked ripening time
Hydraulic kneading silicone O-ring in accordance with the requirements of the specimen thickness showings must be cooked into after showings, hydraulic rubber O-rings deposited in the warehouse, on a flat, clean, dry metal plate is cooled to room temperature (efficient management methods Make rubber is deposited on the trolley to move freely), and then at 23 +/- 2 ? condition, parking 22-24 hours, and to prevent moisture absorption. Silicone back when needed refining, refining shall return roller pitch, roll back requirements mild refining time will be. [View Details] -
Chamfer seal is sealing a connector at the surface, with an O-ring to be fitted into a groove by chamfering generated, then squeezed through the housing to create a seal. The main consideration when designing the product must be slightly stretched, appropriate to reduce the amount of compression, appropriate to increase the fill rate. Chamfering is generally 15 ° ~ 30 °, according to the working pressure selected, under pressure, to an angle close to a small value. On the contrary, whichever is greater.

Design skills of hydraulic seal ring
Chamfer seal is a junction of seal, the O-ring will be fitted to a produced by chamfering groove and then squeeze through the shell to create a seal. The design of the main considerations of the product must be carried out a slight tension, the amount of compression is appropriate to reduce, the filling rate is appropriate to increase. The chamfer is generally 15 degrees ~30, based on the working pressure of selection pressure, angle to converge to the small value. On the contrary, it takes a large value. [View Details] -
Mechanical seal rubber seals use process
Rather than on the end face of the end face of the end face mechanical seal rubber seal usually by moving ring and static ring and the pressing element and sealing element. [View Details] -
Rubber sealing ring how to pick up the best sealing effect
Hydraulic sealing ring primary seal used in static seal and reciprocating motion. When used for rotating seal, only in low speed inversion seal equipment. Rubber sealing ring common equipment in the outer circle and inner circle section within the rectangular groove on sealing effect of rubber sealing ring in the oil resistance, acid-base, grinding, chemical corrosion environment is still good sealing, damping effect. Therefore, O type rubber sealing ring is hydraulic and pneumatic transmission system used most widely used a seal. [View Details] -
Discussion on the type of rubber O ring
(1) the rubber O circle should avoid storage in direct sunlight, moisture and air transfer of local, storage of rubber O-ring for temperature of 0-20 degree, for the humidity in the air for more than 70%. In addition, it should be to prevent the radiation, smoke, insects, rodents, dust, sand, mechanical damage and other damage. [View Details] - The unique structure and working mechanism of the hydraulic seal ring Hydraulic seal ring with its unique structure and working mechanism, so that it has a very wide range of applications, especially the high efficiency of the sand scraper and a long service life and much of the user's favor. Dustproof problem of indoor work of mechanical equipment is not very prominent (except for bad condition). But the equipment of outdoor work, especially the mine, underground, desert, coastal ports, railway transportation, construction machinery etc. hydraulic, hydraulic, pneumatic and electromechanical equipment of dust and sand and mud proof, anti salt spray, anti fungal, anti seawater and other issues, often has attracted attention, and some are even headaches, over the years has been difficult to solve. For example, the seal and dust problem of locomotive and car shock absorber has been very prominent, and the number of shock absorber discarded every year is amazing.Because train a wide range of activities, to coastal, mainland, hot and humid, the alpine zone, to the desert, port hinterland, in short shock absorber seal, asking them to weather resistant performance is good, but the premise is dustproof measures must be guaranteed, that is, to have the high life and efficient anti dust device.owever, in our country at present in this area has not yet pass, because used widely at present is the hydraulic seal pieces and dustproof rubber ring and a small amount of a combination of general dust ring and the sediment often attached on the piston rod, or because of the role of air swirl blowing directly into parts of the dust caused by the dust ring wear serious, sediment directly into the sealed cavity, seal severe wear, even pull the piston rod, shock absorber oil leakage phenomenon is quite common, most of the shock absorber in spite of work, so the locomotive depot and locomotive accessories company are eager to good sealing and dustproof device to solve this problem. In addition ,while the Civil Machinery is Designed and manufactured,we usually care less about the “three anti”(Anti-heat Anti-salt spray Anti-fungal),so the Hydraulic seals and Dust means can Satisfy the “three anti”requirement.Regular dust ring cannot work for long time while the Equipment is covered with salt ,rust,mold, Biofouling,or dust ,which will destroy the Hydraulic seals.the Combination dust ring can perfectly meant the “three anti ”requirements for its Unique selection and Special Structures,it can completely clean out the foreign matter above .it will never appear in the seal chamber .if the Combination dust ring work with chehengde Sealing products,it can improve the capability of “three leakages”of the whole machine and make it work longer than you can imagine? Practice shows that our Hydraulic Dust Seals has the following characteristics : ?1?Flexible automatic compensation function,while the dust ring is fray ,it can heal the gap on the dust ring automatically .and more ,the material of the dust ring is High abrasion resistance,which can make the working life doubled.(2)the non-material ring is Low friction ,High abrasion,high strength,it can not only prevent the dust in ,also can protect the surface of the machine ,which means the Scraper effect is Satisfying .it is perfectly work under the workplace with Sticky dirt.(3) has the advantages of simple structure, convenient installation, is superior to the general combined dustproof ring installation can be operating performance; (4) can be directly into the general combined dustproof ring groove, thus with general combined dustproof ring with interchangeable. In order for the majority of users upgrading; (5) working pressure is between 0 and 40 MPa, operating temperature of - 40 DEG to 200 DEG C, speed 6 m / s, for a variety of mechanical and electrical equipment with the dust. In summary is not difficult to see that a quality and efficient, long-life dustproof device is how important, especially in the military products to reflect this. Believe that in the near future, the combination of hydraulic seals, dust ring in the industry, the Department of mechanical and electrical products to play its unique role. [View Details]

With the progress of science, often is the use of the mixture of several new materials and grafting technology to obtain low cost, superior performance formula. This in the modern commodity economy, competition and crucial. So, rubber formula between the O-ring, value engineering and enterprise benefit, with the strongest determinant of function.
