看懂背後的決策。
01
Use pump_pd for a positive displacement hydraulic pump.
02
Represent the boom cylinder as vessel_h because no dedicated cylinder type exists.
03
Use valve_control for the solenoid actuated 4/3 directional valve.
04
Use hydraulic line type for all process lines and pneumatic/electric for instrument signals.
Reuse for mobile equipment hydraulic P&IDs when the catalog lacks a cylinder type; adapt tags and line sizes per project.
