Seeking advice from experts on split-range control

2017-04-19View Original

Thread Content

I found two different sources online: generally, the air pressure ranges for the two stages in step-controlled systems are typically set at 0.02~0.06 MPa and 0.06~0.10 MPa. One source is correct, while the answer given in the other source is incorrect; please help determine which one is right! 2. In a split-range control system, the range for the split range four is generally set as two pressure segments: 0.02–0.06 MPa and 0.06–0.10 MPa. (×), I don’t understand what this question means; please help me out! Thank you!

It’s already such a late time in the year – and they still use wind pressure-based scoring for exams. How incompetent must the people who create these questions be?

A split-range control system consists of one regulator controlling two control valves. Generally, the split-range signals are 0.2 kg/cm2–0.6 kg/cm2 and 0.6 kg/cm2–1.0 kg/cm2; that is, the actuation signal for one control valve is 0.2 kg/cm2–0.6 kg/cm2, while the actuation signal for the other control valve is 0.6 kg/cm2–1.0 kg/cm2.
