Product Specifications

Technical details and manufacturing context for Hydraulic Dump Cylinder

Definition
A hydraulic dump cylinder is a critical component of a debris hopper system that converts hydraulic pressure into linear mechanical force to raise and tilt the hopper for controlled material discharge. It operates as part of the hopper's dumping mechanism, enabling efficient unloading of debris, waste, or bulk materials.
Working Principle
Hydraulic fluid under pressure from a pump enters the cylinder chamber, acting on a piston. This pressure creates linear force that extends the piston rod, lifting the hopper. Controlled retraction via valve systems allows for precise lowering and positioning.
Common Materials
High-strength alloy steel, Chromium-plated piston rod steel, Polyurethane seals
Technical Parameters
  • Bore diameter and stroke length are primary specifications determining force output and extension range. (mm) Customizable
Components / BOM
  • Cylinder Barrel
    Contains hydraulic fluid and guides the piston; forms the main pressure vessel.
    Material: High-strength alloy steel
  • Piston
    Seals the cylinder bore and converts hydraulic pressure into linear force.
    Material: Steel with polyurethane seals
  • Piston Rod
    Transmits the linear force from the piston to the external load (hopper).
    Material: Chromium-plated steel
  • Rod Gland
    Seals the rod exit point, preventing fluid leakage and contaminant ingress.
    Material: Steel housing with polyurethane seals
  • Mounting Hardware
    Provides the physical connection points between the cylinder and the hopper/frame.
    Material: Steel
Engineering Reasoning
15-210 bar
235 bar (yield strength of SAE 1045 steel at 35 HRC)
Design Rationale: Plastic deformation of cylinder barrel due to hoop stress exceeding material yield strength: σ_h = (P × D)/(2t) where P=235 bar, D=100 mm, t=8 mm
Risk Mitigation (FMEA)
Trigger Contaminant ingress (ISO 4406:2017 Class 22/20/18 exceeded)
Mode: Spool valve stiction causing uncontrolled cylinder extension
Strategy: Integrate 3 μm absolute filtration with differential pressure monitoring at 0.35 bar threshold
Trigger Piston seal extrusion gap exceeding 0.15 mm at 100°C
Mode: Hydraulic fluid bypass causing 35% efficiency loss
Strategy: Implement stepped piston design with 0.05 mm maximum radial clearance at operating temperature
