Hydraulic System Design

Application Brief

Describe the system in normal engineering language. HydroMind extracts requirements, asks the missing engineering questions, calculates pressure and flow, then prepares a design draft for engineering review.

How to Use System Design
5-step guide — from brief to full BOM
▼
1
Enter Your Application Brief
Type your system requirements in plain engineering language — include load, stroke, cycle time, actuator type, environment (offshore/marine), duty cycle, and control method. Use the example presets (Example Winch / Crane) to see the format before entering your own.
2
AI Parses & Asks Clarifying Questions
HydroMind extracts all parameters from your brief, identifies missing values, and asks targeted engineering questions before sizing begins. Answer each question to ensure accurate calculations.
3
Review Pressure, Flow & Sizing Results
The AI calculates system pressure, flow rate, pump displacement, motor torque, pipe sizing, filter rating, tank volume, and cooler sizing. Review each value and override any that don't match your site conditions.
4
Component Selection & Circuit Generation
HydroMind proposes components from its reference material with engineering reasons for each choice — pump model, DCV type, relief-valve setting, filter housing and accumulator. Review the resulting hydraulic circuit against the approved design basis before use.

💡 Pro Tips
Select Metric or Imperial units before starting — this controls all output units throughout the design.
Include the applicable standard in your brief (e.g. DNV, ISO 4413, API) for compliance-based valve and safety system selection.
Mention any OEM preferences (e.g. "Rexroth A10V pump") and HydroMind will prioritise that manufacturer in component selection.

ISO 1219-style twin actuator marine lifting circuit Variable displacement pump draws from reservoir and supplies two closed-centre four-three directional valves. Each double-acting cylinder has a dual load-holding valve. A pressure relief valve protects the pressure line and return flow passes through a cooler and filter to tank.
