Five parameters for anti-surge control
Thread Content
The anti-surge control of the centrifugal compressor has flow rate on the horizontal axis and pressure ratio on the vertical axis, with 5 parameters for control. The inlet has three parameters: flow rate of 47,000 m3/h, 50,000 m3/h after compensation, temperature of 35°C, and pressure of 0.5 MPa. Two parameters for export: temperature 105°C, pressure 0.5 MPa. Ultimately, a command is sent to the anti-surge valve. Discussion 1: How is the flow rate calculated after temperature and pressure compensation? 2: The inlet flow rate, inlet pressure, and outlet pressure are easy to understand in terms of their role in anti-surge control; it’s not clear why the outlet temperature is involved in this control I would appreciate it if colleagues at Haichuan could help answer my questions or recommend book or article titles so that I can search for them.
47,000 (actual flow rate); after voltage stabilization compensation, it becomes 50,000 (flow rate after compensation at 101.325 KPa, 0°C or 20°C). The specific calculation formula can be found on Baidu; one can also seek help from experts in the instrumentation and control section. Temperature compensation is applied to the flow meter at the outlet; if there are other aspects related to this issue, I look forward to expert advice. Once this problem is resolved, it should be posted in the instrumentation and control section
