Workflow map

Start at the stage that matches the job in front of you; each stage links directly to the calculators and lookup tools that support it.

Full tool list
  1. 1

    Size actuators

    Start with hydraulic and pneumatic cylinder force, area, stroke, air-use, receiver-storage, leak-cost and air-pipe sizing screens.

  2. 2

    Check circuit flow

    Estimate pump flow, pump-drive motor current, overload setting, equipment grounding, motor torque, line velocity, NPSH, orifice flow and hose pressure drop.

  3. 3

    Finish support components

    Add accumulator, reservoir, valve Cv, chemical feed and O-ring gland checks.

Tools in this workflow

Calculators come first, followed by lookup tools and reference pages when this workflow needs tabular data.

All Hydraulics

Calculator Hydraulic Cylinder Hydraulic cylinder push/pull force, stroke speed and standard bore sizing. Calculator Hydraulic Cylinder Speed Hydraulic cylinder speed design from bore, rod, stroke and flow, with target-time flow requirements. Calculator Hydraulic Pump Flow & HP Pump output flow and hydraulic/shaft power from displacement, speed and pressure. Calculator Motor Full-Load Amps Formula motor full-load amps from horsepower or kW, voltage, phase, efficiency and power factor, with design-current and service-factor checks. Calculator Motor Overload Size Motor overload relay or heater target setting from nameplate FLA, entered multiplier, selected setting and running-current margin. Calculator Grounding Conductor Size Equipment grounding conductor size from upstream OCPD rating, copper/aluminum material, selected EGC size and voltage-drop upsizing ratio. Calculator Hydraulic Motor Torque Motor torque, required flow and shaft power from displacement, pressure drop and speed. Calculator Hydraulic Fluid Velocity Hydraulic oil velocity, target utilization, required line ID and Reynolds number from flow, actual ID and line type. Calculator Pump NPSH NPSH available, margin and ratio from absolute suction pressure, static head, vapor pressure, line loss and density. Calculator Orifice Flow Rate Liquid orifice flow rate from diameter, pressure drop, discharge coefficient and density, with velocity and mass flow. Calculator Hydraulic Hose Pressure Drop Estimate hose pressure loss, oil velocity, Reynolds number and heat loss from flow, bore and viscosity. Calculator Hydraulic Accumulator Sizing Gas-charged accumulator volume from usable oil volume, precharge and pressure range.

Calculator Pneumatic Cylinder Force Air-cylinder extend and retract force from bore, rod, gauge pressure and efficiency. Calculator Pneumatic Air Consumption Free-air consumption per cycle and per minute for a pneumatic cylinder. Calculator Compressed Air Receiver Sizing Compressed-air receiver volume, stored free air, reserve time, utilization and recharge time from demand, compressor FAD and pressure band. Calculator Compressed Air Leak Cost Compressed-air leak flow, wasted compressor kW, annual kWh, cost and repair payback from measured SCFM or orifice size. Calculator Compressed Air Pipe Sizing Compressed-air pipe velocity, pressure drop, outlet pressure and required actual ID from SCFM/Nl/min, pressure, length, roughness and fittings. Calculator Pneumatic Valve Cv Estimate air valve Cv from flow, upstream/downstream pressure and temperature. Calculator Chemical Feed Rate Water-treatment chemical feed rate, metering-pump setting, mL/min, gpd and day-tank runtime from flow, ppm dose, strength and specific gravity. Calculator O-Ring Gland O-ring squeeze, stretch and gland fill from cross section, installed diameter and groove dimensions.
