Seeking help with diesel constant pressure control

2025-12-09View Original

Thread Content

There is a diesel constant-pressure control system that is required to maintain the pressure in the diesel pipeline at 0.8–1.0 MPa. Currently, there are two approaches: one involves using a pump with a pressure of 3 MPa and regulating the pressure through a control valve using PID control, but I believe this method won’t yield good control results as the pressure remains unstable. Another method is to use mechanical control valves, which are simple and convenient to use; however, there are no suitable manufacturers from whom to choose such valves. If anyone knows any recommendations, please let me know.
