Constant disc spring hangers is to overcome the many shortcomings constant force spring hanger commodity and the successful development of new products, a variety of constant force spring hanger replacement merchandise. Hebei Bo Yan Pipe Constant disc spring hangers using charging assembly GB / T1972 series disc springs by using variational principle-driven organization lever arm, the small amount of deformation and approximately linear change of load into a stable load , and a small amount of deformation of a solid expansion stage. During straight displacement type Constant disc spring hangers will force the displacement decomposition and composition, in order to reach the load was straight displacement of intent. A suitable plan: load planning 500-400000N, shift planning 50-500mm, temperature planning -20 ℃ ~ + 200 ℃. Second, the plan: 1, Thread boom Pendant-21 or JHHDA type 2, the board Pendant -22 type or JHHDB type 3, double plate Pendant or JHHDC type -23, 4, By scheduling or JHHDD placement type-24 type, 5, support or JHHDE placement type-25 type 6, double-threaded boom Pendant or JHHDG type-26, 7, double-threaded boom storey Pendant - 31 or JHPHDA, 8, double-plate Flat Pendant -32 type or JHPHDC type, 9, next scheduling storey or JHHDD placement type-33 type 10, double-threaded boom Vertical Pendant - 34 type or JHLHDA type 11, double plate storey Pendant-35 or JHLHDC type. Yanshan County Bo Yan Pipe Co., Ltd. The company mainly produces steel seamless pipe fittings, steel seam pipe fittings, forged fittings, flanges and other forged products pressure piping components, hangers, products widely used in petroleum, petrochemical , electricity, heating, shipbuilding, construction, oil and gas and other industries, the best-selling domestic 29 provinces, municipalities and autonomous regions. Stand-tuning a spring assembly, use and principles spring hanger is mainly used for power plant piping or soda boiler equipment, generating heat displacement and its facilities and equipment in operation. The plumbing calculate the forces determined spring hangers work and thermal displacement requirements, Xuzhou hangers, spring hangers factory will follow the design load tuning: the spring preload and cold predetermined load position; and superscript and the theory work place when cold. Spring hanger manufacturer in the factory were tuning to the rear when installed piping and equipment, Hebei hanger, make relevant thread adjustment, disengage the lock pin, Bozhou hanger, then actual bearing spring Cold load is required by the design. Second, the model, the type of a variable spring hanger has four series, mainly by the Northwest Electric Power Design Institute of T1, T2, T3, T4, T5 series, East China Electric Power Design Institute of TH1, TH2, TH3 type series, TD series (JB / J8130.2-1999) and Chemical Design Institute VS series, the same basic characteristics of their family, carrying capacity 20daN-21000daN. There are suspended structure, supporting type and parallel suspension-supporting. Nanjing hangers, hangers, Bo Yan Pipe (view) provided by the Yanshan Xian Yan Bo Industry Co., Ltd.
