When purchasing hydraulic power stations, many customers initially provide only equipment size and required pressure. However, reliable configuration cannot be determined from these two parameters alone. The following five parameters are the first items Liqiang Hydraulic confirms during project discussions.
I. Working Pressure & Peak Pressure
Working pressure determines component pressure ratings; peak pressure affects safety margins for valve manifolds and piping. Specify both normal operating pressure and possible transient surge pressures to avoid premature component failure due to average-value-based selection.
II. Flow Rate & Actuation Cycle
Flow rate governs actuator speed; actuation cycle determines whether accumulators or dual-pump switching are needed. For multi-actuator systems, provide concurrent actuation combinations and timing sequences for each motion.
III. Oil Temperature & Heat Dissipation Conditions
For continuous-duty equipment, calculate heat generation to determine cooler capacity and tank volume. In high-temperature or dusty environments, consider cooler clog resistance and service accessibility.
IV. Installation Space & Maintenance Access
Tank, motor-pump unit, valve block, and cooler layout affect on-site installation and long-term maintenance. Providing equipment layout drawings early minimizes re-piping and rework.
V. Control Method & Safety Requirements
Manual, solenoid, proportional, or servo control require vastly different valve manifolds and electrical configurations. For safety-critical functions—e.g., pressure holding, synchronization, or anti-fall protection—requirements must be clarified at the proposal stage.
Clarifying these five points ensures technically comparable proposals and quotations. Liqiang Hydraulic can supply schematic diagrams and configuration lists tailored to your equipment’s motion requirements—contact us to discuss.
