The Variable Spring hanger(spring hanger for short)serial products by our company meet NB/T47039-2013standard requirement,the hangers will be reset prior to delivery and attach the product quality certificates and operation&adjustion instruction,the site shall read double instruction prior to installation.The manual introduce installation,operation and adjustion is base on TD serial products,others type products,such as VS serial,T serial,TH serial and DLTH serial, which O&M shall refer to the manual.1安装调整前须知Operational Requirements prior to installation1.1弹簧支吊架用来支吊具有垂直位移的管道或设备，其内部装有圆柱螺旋压缩弹簧，以满足管道或设备热膨胀的需要。
Spring hanger is used to support and hanger the pipe or facility,which has vertical movement,cylindrical and helical compress spring will be placed inside hanger to satisfy the pipe or facility hot expansion requirement.1.2弹簧支吊架主要由圆柱螺旋弹簧、位移指示板、壳体、和花兰螺丝等构成，其典型结构如图1所示。
The spring hanger contains cylindrical and helical compress spring,movement indicator,sleeve and turnbuckle etc..,the type construct is shown as below figure1:Top plate Movement indicatorSpringNameplate SleeveTurnbuckle Bottom plate图1典型结构图Figure1,type construction1.3弹簧支吊架的型式和常用生根支吊方式示意图如图2所示。
The spring hanger type and common supporting and hangering plan are shown as below figure2:图2Figure21.4弹簧支吊架铭牌如图3A所示。

The spring hanger delivery status is locked with upper stop and hydrostatic stop according to installation(cold)load,the clearance between hydrostatic stop with movement indicator is2mm,and the hydrostatic stop is tied with wire,see figure3B.Top plateUpper stopMovement indicatorCold load(install load) clearance WireHot load(work load)NameplateHydrostatic stop(2sets)Sleeve图3B弹簧支吊架出厂状态Figure3B,spring hanger delivery status2弹簧支吊架的安装Principle of installation about spring hanger2.1安装前应仔细阅读弹簧支吊架铭牌标识，铭牌中的型号、安装载荷、工作载荷、位移量和花兰螺丝规格等应符合工地安装施工图要求。
Read the spring hanger nameplate with care,the content in the nameplate shall conform to the requirement of site erection,it contains specification,cold load,hot load,movement,turnbuckle,thread size etc..2.2按安装施工图要求，用起重工具将弹簧支吊架生根固定在钢结构上。
Attach the spring hanger to the steel shapes with lift facility according to erection drawing.2.3将被支吊的管道或设备加以临时固定并找好水平，把吊杆螺栓旋入花兰螺丝内，并旋紧花兰螺丝带上载荷，卸除临时固定，此时弹簧支吊架的上、下限位块有可能松动，但不要取出，待管道水压试验后再取出。
Temporarily attach the pipe or facility to be hung or supported and make them horizontal,then put the thread rod into turnbuckle,rotate the turnbuckle to load,finally remove the temporary attachments.At that time,spring hanger’s upper stop and hydrostatic stop may be loose,but don’t remove,this may be removed after hydrostatic test is completed.3弹簧支吊架的载荷调整Loading adjustment of spring hanger3.1当管道或设备水压试验和冲洗完毕后，须逐台进行载荷调整，取出限位块。
Adjust the spring hanger load one by one after pipe or facility hydrostatic testand rinse is completed3.2弹簧支吊架出厂状态图3B所示，上限位块与顶盖板被弹簧顶紧没有间隙，下限位块与位移指示板下留有2mm间隙，上、下限位块的取出靠载荷调整出现间隙来完成，如图4(b)所示。
The spring hanger delivered as shown in above figure3B,the clearance between the upper stop with hanger top plate inexistence,between hydrostatic stop with movement indicator is2mm,take out the upper stop and hydrostatic stop through adjusting load to appear clearance only,it is Show as figure4--(b).（a）(b)(c)图4载荷调整时支吊架间隙形式Figure4,support or hanger clearance type as load adjusting3.3载荷调整方法Load adjustment method:3.3.1图4（a）所示，上限位块与吊架顶盖板之间有间隙，下限位块与位移指示板之间也有间隙，说明管道的实际载荷与吊架安装载荷相同，无须调整，上、下限位块可同时用手取出。
If t here is clearance between both the upper stop with hanger top plate,but no clearance between hydrostatic stop with movement indicator exits from figure4(a), then the actual load is the same as the hanger cold load and no need to adjust, then the upper stop and hydrostatic stop can be removed.3.3.2图4.（b）所示，上限位块与吊架顶盖板之间无间隙，下限位块与位移指示板之间有间隙，说明实际载荷小于安装载荷，此时用工具旋紧花兰螺丝加载，直至上限位块与吊架顶盖板之间出现间隙，可同时用手取出上、下限位块。
