Technical details and manufacturing context for Pressure/Vacuum System

Definition
The Pressure/Vacuum System is a critical component of the Test Chamber Module that generates, maintains, and regulates either positive pressure or vacuum conditions inside the chamber. It enables simulation of various atmospheric conditions for testing products under controlled pressure environments, essential for aerospace, automotive, electronics, and materials testing applications.
Working Principle
The system typically consists of pumps (vacuum pumps for creating vacuum, compressors for creating pressure), valves, pressure sensors, and control units. It works by either removing air molecules from the chamber to create vacuum or introducing compressed air/gas to create positive pressure, with feedback control systems maintaining precise pressure levels as required by test protocols.
Common Materials
Stainless steel, Aluminum alloys, High-grade seals and gaskets
Technical Parameters
  • Pressure range capability from high vacuum to positive pressure (Pa) Per Request
Components / BOM
  • Vacuum Pump
    Removes air and gases from the chamber to create vacuum conditions
    Material: Stainless steel, aluminum
  • Pressure Compressor
    Compresses air/gas to create positive pressure conditions in the chamber
    Material: Stainless steel, cast iron
  • Pressure Control Valve
    Regulates and controls the pressure level within the chamber
    Material: Brass, stainless steel
  • Pressure Sensor
    Measures and monitors the pressure inside the chamber
    Material: Stainless steel, ceramic
  • Control Unit
    Electronic system that manages and automates pressure/vacuum operations
    Material: Plastic, aluminum, electronic components
Engineering Reasoning
0.001-10 bar absolute (100 Pa to 1 MPa)
0.0001 bar absolute (10 Pa) for vacuum integrity loss, 15 bar absolute (1.5 MPa) for pressure containment failure
Design Rationale: Vacuum failure occurs at 10 Pa due to molecular flow regime transition where mean free path exceeds chamber dimensions, causing gas conduction breakdown. Pressure failure at 1.5 MPa results from yield strength exceedance of 316L stainless steel (205 MPa) at stress concentration points with safety factor of 3.
Risk Mitigation (FMEA)
Trigger Oil contamination in vacuum pump reaching 100 ppm concentration
Mode: Vapor backstreaming causing chamber contamination reaching 1E-6 Torr·L/s leak rate
Strategy: Install liquid nitrogen cold trap at 77K with activated charcoal adsorption stage
Trigger Thermal cycling between 293K and 423K at 10K/min rate
Mode: Bellows fatigue cracking after 10,000 cycles at stress amplitude of 150 MPa
Strategy: Implement Inconel 718 bellows with shot peening to induce 400 MPa compressive surface stress
