Product Specifications

Technical details and manufacturing context for Hydraulic Power Unit

Definition
The hydraulic power unit is a critical component of a hydraulic press brake that provides the pressurized hydraulic fluid required to drive the ram and perform bending operations. It serves as the central power source for the entire hydraulic system of the press brake.
Working Principle
An electric motor drives a hydraulic pump that draws fluid from a reservoir, pressurizes it, and delivers it through control valves to the hydraulic cylinders. The system maintains pressure and flow to enable precise control of the press brake's bending force and speed.
Common Materials
Steel, Cast Iron, Aluminum
Technical Parameters
  • Motor power rating (kW) Customizable
Components / BOM
Engineering Reasoning
50-350 bar
420 bar (burst pressure of SAE 100R2AT hose at 93°C)
Design Rationale: Cavitation-induced erosion at vapor pressure threshold of 0.023 bar absolute (at 20°C hydraulic oil)
Risk Mitigation (FMEA)
Trigger Particulate contamination exceeding ISO 4406 18/16/13 cleanliness level
Mode: Servo valve spool seizure
Strategy: Integrate 3 μm absolute beta₃≥200 filter with pressure differential monitoring
Trigger Continuous operation at 95°C oil temperature exceeding 1000 hours
Mode: Seal hardening and leakage at 0.1 mL/min threshold
Strategy: Implement plate heat exchanger maintaining 45-65°C with ΔT=15°C

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Cavitation
Cause: Inadequate fluid supply, excessive pump speed, or high fluid temperature causing vapor bubble formation and implosion on metal surfaces.
Internal leakage
Cause: Worn seals, scored cylinder walls, or damaged valve seats allowing fluid bypass, reducing pressure and efficiency.
Maintenance Indicators
  • Unusual knocking or whining noises from the pump indicating cavitation or bearing wear
  • Visible external fluid leaks or significant pressure drop during operation
Engineering Tips
  • Implement strict fluid cleanliness protocols with regular filtration and contamination monitoring
  • Maintain proper fluid temperature and viscosity through adequate cooling and scheduled fluid analysis/replacement

Compliance & Manufacturing Standards

Reference Standards
ISO 4413: Hydraulic fluid power - General rules and safety requirements for systems and their components ANSI/NFPA T2.6.1: Hydraulic fluid power - Systems and components - Pressure ratings DIN 24340: Hydraulic power units - Dimensions and requirements
Manufacturing Precision
  • Cylinder bore diameter: +/-0.02mm
  • Mounting surface flatness: 0.1mm per 100mm
Quality Inspection
  • Pressure testing: Hydrostatic test to 1.5x maximum working pressure
  • Leakage testing: System leakage check at maximum operating pressure
