冷热水循环系统运行状态评估

离心泵出口管路及其附属设备的设计压力基准应取泵在全关闭状态下运行时的最大工作压力-即关死点压力值，并在此基础上确保设计的安全性

固定转速离心泵性能曲线可用时

泵出口设计压力值通过以下公式之一计算：

Ps=Mop+(Hs×ρ×g/1000) （1）

Pd=Ps+(Hc×ρ×g/1000) （2）

其中：

Pump outlet design pressure of Pd is expressed in barg units.

The rated head Hc is typically achieved when the pump operates at its nominal flow rate, ensuring optimal efficiency under these conditions.

This parameter is influenced by factors such as pump structure, impeller design, and fluid properties affecting performance metrics.

The pumped fluid's maximum density ρ is a critical parameter for determining system performance limits.
