Pressure/Vacuum System for Test Chambers

Product Specifications

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. 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. Key parameters include an operating pressure range of 1.0–1.6 MPa, a vacuum range of 0.1–101.3 kPa absolute, pressure accuracy of ±0.5% FS, vacuum accuracy of ±0.1 kPa, and a helium leak rate of ≤1×10⁻⁹ Pa·m³/s (ISO 21360). The system operates within an ambient temperature range of -40 to 85 °C, requires a 220–240 V AC, 50/60 Hz single-phase power supply, and consumes 1.5–3.0 kW depending on pump size. Ingress protection is IP54–IP65 (IEC 60529), wetted parts are made of 316L stainless steel (ASTM A240), and the system weighs 150–300 kg with dimensions varying from 800×600×1200 to 1200×800×1500 mm. Materials on file include stainless steel, aluminum alloys, and high-grade seals and gaskets. This directory entry provides reference values; actual model-specific specifications and standards compliance must be verified with the legal manufacturer or supplier.

Working Principle

The system uses pumps to either evacuate air from the chamber to create vacuum or compress air/gas to build positive pressure. Valves control flow, pressure sensors monitor levels, and a control unit adjusts operations based on feedback to maintain the setpoint. For vacuum, a vacuum pump removes air molecules; for pressure, a compressor introduces gas. The control system ensures precise regulation within the specified accuracy.
