30-year seal manufacturers Yada Industry and Trade Tianjin imported seals _ [] _ ??imports of seal provided by Jada Trade and Industry. We are Tianjin Adar Ltd. (www.yada-mfj.com) in: Tianjin professional: the production of various seals, sealing tape, seal, and a variety of custom shaped miscellaneous pieces on conventional Product: refers to the general application of hydraulic machinery seal products, and products in the company's product lines, inventory and supply series has been widely adopted in the hydraulic system and the market, the product has been systematically included in the company's product catalog the. About Professional Products: refers to professional mechanical seal products, to meet a particular purpose of the hydraulic system imported seals, such as buffer ring construction machinery, high pressure seal ring; special mechanical seal height and safety on the job pieces; temperature seals and cold cryogenic mechanical seals on the high-temperature mechanical; high pressure seals and other high-voltage rotating machines, these products are not included in this catalog. About general machinery: general machinery referred to here is the hydraulic machinery and equipment used in the general pressure, speed, temperature, level and other occasions, there is no very special requirements of its safety systems, tasks and operating characteristics, and therefore the use of seal products will not make excessive performance requirements, such as the common hydraulic machine, general machine tools, forklifts, plastic machines and light machinery. About Professional Mechanical: specialized machinery is referred to here in particular pressure, speed, temperature, level and special occasions, application of professional hydraulic machinery and equipment, it has a certain security systems, tasks, operating characteristics, environmental conditions and other specialized requirements, so that it can effectively complete the assigned special tasks, so this type of machinery used for seal products have a special performance requirements (if any particular reliability, pressure resistance, speed performance, the performance of certain aspects of temperature, durable performance and safety, etc.), this type of machinery such as aerial work machinery, cranes, mining machinery, steel, machinery, port machinery and some maintenance equipment. About maintenance products: mechanical equipment is being used when the hydraulic system failure occurs, the urgent need to replace the hydraulic seals, hydraulic equipment, or when the system needs to transform imported seals agents, re-select the proper application of the seal. Supply characteristics of such products requires timely, accurate, effective and reliable in this respect my company has excellent technical assurance and product assurance. Seals of Grameen circle to circle grid: grid to circle is made with a rubber O-ring seals PTFE qualitative superposition of Use constitute the square, the circle can be divided into grid to grid to circle hole and shaft with the cell to ring, but they are the same sealing mechanism, a hydraulic working cylinder Tianjin imported seal oil pressure so that the elastic deformation of O-ring seals extruded square, so close to the sealing surface, and in contact with the initial stress together to stop the oil leak pressure.
