Product Specifications

Technical details and manufacturing context for Stopper Insertion Cylinder

Definition
A hydraulic cylinder component within a Hydraulic Stoppering System that provides the precise linear force and motion required to insert stoppers, plugs, or caps into containers or production line fixtures. It ensures controlled insertion depth and pressure for proper sealing.
Working Principle
Converts hydraulic pressure into linear mechanical force via a piston moving within a cylinder barrel. Hydraulic fluid is directed to extend or retract the piston rod, which is connected to the stopper insertion mechanism.
Common Materials
Chrome-plated steel, Sealing elastomers
Technical Parameters
  • Bore diameter and stroke length (mm) Standard Spec
Components / BOM
  • Cylinder Barrel
    Houses the piston and hydraulic fluid, provides structural integrity
    Material: Chrome-plated steel
  • Piston
    Converts hydraulic pressure into linear force
    Material: Steel with sealing rings
  • Piston Rod
    Transmits force to the stopper insertion mechanism
    Material: Hardened steel
  • End Caps
    Seal the cylinder ends and provide mounting points
    Material: Steel
Engineering Reasoning
50-200 bar hydraulic pressure, 0-100°C fluid temperature, 0.5-2.0 m/s piston velocity
Seal failure at 250 bar pressure differential, piston scoring at 150°C fluid temperature, cavitation at 0.1 bar absolute pressure
Design Rationale: Seal extrusion failure due to 250 bar exceeding Shore A 90 nitrile rubber yield strength, thermal degradation of hydraulic fluid at 150°C exceeding ISO VG 46 thermal stability limit
Risk Mitigation (FMEA)
Trigger Particulate contamination exceeding ISO 4406 18/16/13 cleanliness level
Mode: Spool valve sticking causing 500 ms response delay
Strategy: Install 10 μm absolute beta₃≥200 filter with differential pressure monitoring
Trigger Water contamination exceeding 500 ppm in hydraulic fluid
Mode: Cylinder rod corrosion pitting at 0.5 mm depth
Strategy: Implement vacuum dehydration system maintaining <100 ppm water content

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Seal degradation
Cause: Contamination ingress (particles, moisture) or chemical incompatibility leading to hardening, cracking, or extrusion of seals, resulting in fluid leaks and loss of pressure.
Rod scoring or bending
Cause: Misalignment during installation or operation, side-loading forces, or inadequate rod wiper/seal allowing abrasive contaminants to damage the rod surface, leading to seal wear and potential cylinder binding.
Maintenance Indicators
  • Audible hissing or squealing during operation indicating air or hydraulic fluid leakage past seals.
  • Visible fluid leaks around rod seals or cylinder body, or erratic/jerky movement during insertion cycles.
Engineering Tips
  • Implement strict contamination control: use high-quality filters, ensure clean fluid, and install effective rod wipers to prevent abrasive particles from entering the cylinder.
  • Ensure precise alignment during installation and use proper mounting hardware to avoid side-loading; regularly check mounting bolts and alignment to prevent rod bending or seal wear.

Compliance & Manufacturing Standards

Reference Standards
ISO 6432:2015 (Pneumatic cylinders - Bore diameters and piston rod diameters) ANSI/B93.5M-1995 (Hydraulic fluid power - Cylinders - Bore and rod area ratios) DIN ISO 3320:2017 (Fluid power systems and components - Cylinder bores and piston rod diameters - Metric series)
Manufacturing Precision
  • Bore diameter: +/-0.02 mm
  • Piston rod straightness: 0.05 mm per 300 mm length
Quality Inspection
  • Pressure test (leakage and burst resistance)
  • Dimensional verification (CMM measurement)
