  装配式支架设备是管道体系的重要组成部分,起着接受管道荷载、约束管道位移量和操控管道振动的重要作用.支吊架配置(荷载状况、类型、方位)直接影响管系的应力散布和大小,其功能的好坏、承载是否合理都直接影响管道的使用寿命及安全运转
  Assembled bracket equipment is an important part of pipeline system, which plays an important role in receiving pipeline load, restraining pipeline displacement and controlling pipeline vibration. The distribution and size of stress in pipeline system are directly affected by the configuration of bracket and hanger (load status, type and orientation). Its function and reasonable load-bearing directly affect the service life and safe operation of pipeline.
  因为管道支吊架在规划、装置过程中可能存在超导主动防爆门一些问题复合绝缘子 ,加上经一段时间运转后,管线的形状、方位以及支吊架绷簧等部件的功能等可能发作一定改变,发作支吊架损坏、过载、欠载及位移受阻等问题,形成管道部分区域滚珠丝杠应力增高、对端点(或设备)推力增大等状况.这些问题的出现必然会影响到设备运转的安全性和经济性
  Because there may be some problems of superconducting active explosion-proof door in the process of planning and installation of pipeline support and hanger, composite insulator, and after a period of operation, the shape, orientation of pipeline and the function of components such as support and hanger tension spring may change to some extent, and the problems of damage, overload, under-load and displacement hindrance of support and hanger may occur, resulting in increased stress of ball screw in some areas of pipeline. Increased thrust on endpoints (or equipment). These problems will inevitably affect the safety and economy of equipment operation.
  装配式支架未曾对各首要管道支吊架的受力状况和运转状况进行过体系的检验、剖析及调整.为了解决管道支吊架在规划、装置和运转中存在的问题,消除因为支吊架受力不合理引起的机组安全运转隐患,存在较多影响管道寿命和安全运转的隐患.我们对机组主蒸汽粘土稳定剂 酸化缓蚀剂、再热热段蒸汽、高压旁路阀前及低压旁路阀前管道支吊架进行检验、剖析,以期改进管道及支吊架的运转状况,达到设备安全、经济运转之目的
  In order to solve the problems existing in the planning, installation and operation of pipeline support and hanger, eliminate the hidden danger of unit safe operation caused by unreasonable force of support and hanger, and there are many hidden dangers affecting the service life and safe operation of pipeline. Inspection and analysis of stabilizer acidification inhibitor, reheat steam, high pressure bypass valve front and low pressure bypass valve front pipeline support and hanger are carried out in order to improve the operation status of pipeline and support and hanger and achieve the purpose of safe and economic operation of equipment.

  由制造厂按用户供给的装置载荷,用上、下两块定位块将装配式支架的指示板固定在与装置载荷相应的方位上,使装配式支架暂处于刚性状况.装配式支架管道经清洗、水压试验后,取下上、下定位块,方可将管道投入使用.管道开始运转时,首先查看装配式支架定位块是否合部拆除,再查看指示板从装置载荷到作业载荷的乳化沥青设备
  According to the device load supplied by users, the manufacturer fixes the indicator plate of the assembled bracket on the position corresponding to the device load with the upper and lower positioning blocks, which makes the assembled bracket temporarily in a rigid state. After cleaning and hydraulic test, the upper and lower positioning blocks are removed before the pipeline can be put into use. When the pipeline starts to run, first check whether the positioning block of the assembled bracket is available or not. Remove the joint and check the emulsified asphalt equipment of the indicator board from device load to operation load
  改性沥青设备位移过程中有无卡阻现象.管道投入正常运转后,查看装配式支架在作业载荷 时的位移是否与规划共同.管道停止运转后,查看装配式支架指示板是否复位到装置载荷的方位当管道或设备产生位移时,只要在预先选定的载荷位移内,不论其位移改变有多大,它们能够通过恒力绷簧支架而一直取得恒定的支撑力
  After the pipeline is put into normal operation, check whether the displacement of the assembled support is in accordance with the plan. After the pipeline stops running, check whether the indicator plate of the assembled support is reset to the direction of the device load. When the pipeline or equipment displaces, as long as the displacement of the pipeline or equipment is within the pre-selected load displacement, no matter how large the displacement changes, it will be. They are able to maintain a constant support force through a constant-force spring bracket.
  从而装配式支架就不会给管道或设备带来新的附加压力,这样就能够避免形成严重的设备和安全事故.在使用过程中应严格按照装配式支架的规范作业,以防发作安全事故。
  Therefore, the assembled bracket will not bring new additional pressure to the pipeline or equipment, so that serious equipment and safety accidents can be avoided. In the use process, the standard operation of the assembled bracket should be strictly followed to prevent accidents.
