电动阀数字式水击实验台
Designers limit surge by choosing valve closing times, and this rig lets students test that directly. A servo ball valve closes in a settable 0.05–10 s at the end of a 50 m coiled stainless pipe. Five 0–4 MPa transducers at 0.1 % FS sample at 50 kHz, and the software compares results with a method of characteristics model.
