Introduction The General Purpose Pneumatic Test Rig is a high-performance, computer-controlled test system developed to conduct comprehensive performance evaluation, validation, and qualification of pneumatic systems and components. Designed for aerospace, defense, and high-reliability industrial applications, this rig provides engineers and technicians with the ability to precisely replicate operating conditions, measure critical performance parameters, and ensure compliance with international quality and safety standards. Modern aircraft and defense platforms rely extensively on pneumatic systems for actuation, braking, pressurization, emergency systems, and auxiliary operations. Any malfunction in these systems can compromise mission safety. This rig is therefore engineered to perform end-to-end testing of valves, actuators, regulators, control units, manifolds, and complete pneumatic assemblies with a level of accuracy, repeatability, and reliability that exceeds manual inspection or basic bench setups. System Overview The rig integrates mechanical, pneumatic, electronic, and software subsystems into a robust and modular platform. Its dual pressure line configuration allows both high-pressure (up to 200 kgf/cm2) and low-pressure (up to 8 kgf/cm2) operations, enabling it to simulate a wide variety of operating conditions. The working fluid is ultra-clean, dry compressed air, conditioned with a dew point of -55°C and filtered to a particle purity better than 2 microns. This ensures the elimination of contaminants and moisture, protecting sensitive pneumatic components and yielding accurate, repeatable test results. Key system highlights include: • High-accuracy electronic flow meters for real-time flow measurement. • Digital pressure transducers and sensors to capture minute pressure variations and leakages. • Fully automated test sequencing software with programmable routines for different components. • PC-based data acquisition and control system for real-time monitoring, test control, and archival of test data. • Safety interlocks, overpressure protection, and emergency shut-off features to safeguard both the equipment and operator. Functional Capabilities The General Purpose Pneumatic Test Rig is capable of performing a broad spectrum of tests, such as: 1. Leakage (Air Tightness) Tests ▹ Detects micro-leakages in pneumatic circuits, valves, and actuators. ▹ Capable of performing both static leak tests (at fixed pressures) and dynamic leak tests (under flow). 2. Flow Measurement & Characterization ▹ Determines flow coefficients (Cv values) and verifies rated flow capacity. ▹ Characterizes pressure vs. flow behavior under varying load conditions. 3. Pressure & Overload Testing ▹ Simulates operational pressure cycles. ▹ Validates burst pressure and withstand pressure of components. 4. Functional Performance Testing ▹ Checks response times of valves, regulators, and actuators. ▹ Verifies operational efficiency and functional integrity. 5. Efficiency & Performance Benchmarking ▹ Compares actual vs. theoretical performance. ▹ Enables early detection of design or manufacturing defects. Software & Automation A critical feature of the rig is its customized software platform, designed for automation, repeatability, and advanced data analysis. • Pre-programmed Test Routines: Standardized test procedures for common pneumatic components (valves, regulators, actuators) reduce operator input and error. • Customizable Test Sequences: Engineers can create bespoke test programs for specialized components. • Data Logging & Storage: Complete test data (flow, pressure, leakage, response time) is stored in a secure database. • Data Visualization: Graphical user interface (GUI) allows real-time display of test curves, performance graphs, and live monitoring dashboards. • Report Generation: Test results can be automatically compiled into PDF/Excel reports for traceability, customer handover, and audit compliance. • Calibration & Diagnostics: Integrated self-check and calibration modules ensure long-term accuracy and compliance with standards.
