| 摘 要： | 举例说明离心泵和压缩机管路系统设备设计压力确定方法。对于离心泵管路系统,泵出口侧设备设计压力应等于或大于泵吸入侧容器最高压力、出口关闭压差及吸入侧最高静压头之和;对于压缩机回路系统,操作压力最低设备的设计压力可取停机稳定压力的1.05倍,其它设备设计压力等于操作压力最低设备设计压力加上两设备之间的最大压降。

| Abstract: | The calculation methods of the equipment design pressure in pump or compressor piping loops were provided with examples.The design pressure of the equipment in a centrifugal pump discharge circuit was equl to or greater than that of the summation of the maximum operating suction pressure,the pump shut off pressure and the maximum suction static head.In a compressor loop,the design pressure of the lowest operating pressure would be 1.05 times the settle-out pressure,and the design pressure of the other equipment would be that of the lowest operating pressure equipment and plusing the pressure difference between them. |
