重载恒力弹簧箱.doc

高精度恒力弹簧箱一、 概述JN系列弹簧箱广泛适用于化工设备、化工管道及大型锅炉等有附加载荷和位移的管道或设备，起平衡和减震的作用。重载恒力弹簧箱所支撑的管道或设备在发生热位移时，不会对管道或设备产生任何附加的应力，以确保管道和设备的安全。高精度恒力弹簧箱适用的载荷范围为2.5 kN2000kN；适用的位移范围为0300 mm，分为050 mm，0100 mm，0150mm，0200 mm，0250 mm，0300 mm六种位移量；使用温度为 20220，共390种规格。JN系列高精度恒力弹簧箱的工作原理是利用多个弹簧力的相互叠加作用，补偿管道和设备发生热位移时所产生的附加应力，深受广大石化、锅炉、电站等用户的好评。我们还可为用户提供来图定制业务或代客户设计特殊规格、特殊用途的组合恒力弹簧箱。二、 结构及分类重载恒力弹簧箱由弹簧箱、底板、顶板（载荷板）、箱体、标尺等组成，并设有调整螺栓，可调整载荷大小，见图1。图1 重载恒力弹簧箱结构及安装示意图1底板；2箱体；3弹簧箱；4位移标尺；5顶板JN系列恒力弹簧箱有以下五种型号供用户选择：1 JNHXA型为单组组合恒力弹簧箱，载荷范围为2.5 kN400 kN。2 JNHXB型为双组组合恒力弹簧箱，载荷范围为5 kN800 kN。3 JNHXC型为三组组合恒力弹簧箱，载荷范围为7.5 kN1200 kN。4 JNHXD型为四组组合恒力弹簧箱，载荷范围为10 kN1600 kN。5 JNHXE型为五组组合恒力弹簧箱，载荷范围为12.5 kN2000 kN。三、 型号编制说明 例如：1. JNHXA-12-20/320000表示单组组合恒力弹簧箱，支架编号为12号弹簧箱，计算位移为20 mm，方向向下，工作载荷为320000 N。2. JNHTE-07-36/500000表示五组组合恒力弹簧箱，支架编号为07号弹簧箱，计算位移为36 mm，方向向上，工作载荷为500000 N。四、 弹簧箱载荷、位移1.
