管子重量偏差、加工和安装误差、保温重量的变化及弹性吊架的自重和荷载偏差等因素 ,会对汽机设备的推力产生不可预见的影响。除了在管道设计时要充分考虑各种影响因素外 ,主要应通过浮动连接手段 ,可有限地预防和消除上述影响。实施浮动连接前 ,应保证管道没有垂直方向上的附加力 ,应选用合适的端点约束刚度 ,弹簧或恒吊应具有足够的调整裕量 ,并安装有必要的调整段 Pipe weight deviation, processing and installation errors, changes in insulation weight and elastic hanger self-weight and load deviation and other factors, the thrust of the turbine will have unpredictable effects. In addition to fully consider the various factors in the pipeline design, mainly through the floating connection means, can be limited to prevent and eliminate the above effects. Before implementing a floating connection, ensure that there is no additional force in the vertical direction of the pipe. The proper end restraint stiffness should be used. The spring or constant weight should have sufficient adjustment allowance and the necessary adjustment section
