二次联轴器对中和与泵法兰对口的管道法兰安装结束后，管道应力测试工作应被

After the installation of the secondary coupling and the pipe flange that is opposite to the pump flange, the pipe stress test should be carried out. First of all, the two dial gauges are installed on the motor shaft by means of the magnetic table base. The pointer points to the pump-side coupling on two vertical surfaces, one axial and one radial. The index returns to zero, and then the pipeline flange and the pump flange are bolted. The bolting is continuously completed. The initial tightening force of the flange bolt is 10% of the total torque value, and it is tightened again to 30% of the total torque. The final tightening is 100% of the total torque (the torque value of the pipe bolts is specified or designed by the equipment manufacturer).

After the installation of the pipe flange of the secondary coupling alignment and the opposite of the pump flange, the pipe stress test work should be carried out. First, the two percentage tables are mounted on the motor shaft by magnetic table seat adsorption, the needle points to the joint shaft on the pump side into two vertical faces, one axial, one radial, the index of the percentage table zero, and then the pipe flange and Pump flanges are bolted, bolted are continuously completed, the flange bolts are initially tightened at 10% of the total torque value, again tightened to 30% of the total torque, and finally 100% of the total torque (pipe bolt torque value is specified or designed by the equipment manufacturer).

After the secondary coupling alignment and the installation of the pipe flange corresponding to the pump flange are completed, the pipe stress test shall be carried out. First of all, two dial indicators are installed on the motor shaft by the way of magnetic base adsorption. The indicator needle points to the two vertical surfaces on the coupling at the pump side, one axial and one radial, and returns the index of the dial indicator to zero. Then, the pipeline flange and the pump flange are bolted, and the bolt fixation is completed continuously. The initial tightening force of the flange bolt is 10% of the total torque value, and then it is tightened to the total torque again 30% of the torque, and the final tightening is 100% of the total torque (the torque value of the pipe bolt is specified or designed by the equipment manufacturer).
