Lo scenario
A mobile crane service truck requires a P&ID to document the hydraulic power path for its lifting arm and stabilizing outriggers, including closed-loop pressure control.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
01
Use a positive-displacement hydraulic pump and atmospheric reservoir for oil supply.
02
Split the pump discharge through isolation and check valves to independent arm and outrigger directional control valves.
03
Add pressure transmitters and shared controllers on each branch to provide closed-loop pressure control.
Reuse for any hydraulic circuit where multiple actuators share a common pump and require independent directional control and pressure monitoring.
