Ten-Station Relay Charging & Evacuation System for Automotive Components | High-Precision Auto Parts Test Equipment for Leak, Pressure & Vacuum Control

The 10-station relay inflation/deflation equipment (HJ222-1) is specifically designed for inflation, vacuuming, and airtightness testing of automotive relays and small airtight components.

Ten testing stations operate synchronously, making the production line more efficient every minute; a stable pressure control system and automatic data recording module ensure that every product receives accurate and traceable test results.

The equipment employs industrial-grade pneumatic control, proportional valve pressure regulation, precision pressure sensors, and customized fixtures, forming a highly automated and stable production testing unit. Whether used for pre-processing at the front end of the production line or for final factory inspection, it significantly improves efficiency and product consistency.

• Ten Times Efficiency, Uncompromising Quality (High-Throughput 10-Station Design): Simultaneously performs independent charging/venting or airtightness tests on 10 relays, significantly improving your testing efficiency in R&D verification (DV/PV) and end-of-line (EOL) processes.
• High-Precision Control: Employs imported high-precision pressure sensors and control valves, achieving pressure control accuracy of ±0.5% F.S., detecting even the smallest leaks and ensuring zero-defect shipments.
• Intelligent Core, Worry-Free Operation (PLC & Touch-Screen Control): Equipped with a Siemens/Mitsubishi PLC intelligent control system and a 7-inch high-definition touchscreen. One-button start for the testing process, intuitive and simple parameter settings, and automatic data storage minimize human error.
• Comprehensive Safety Protection: Features overpressure alarms, pressure misoperation protection, and an emergency stop button, ensuring the absolute safety of operators and the equipment itself.
• Flexible & Customized Fixtures: We offer customizable flexible test fixtures that can be quickly changed for relays of different sizes and types, truly achieving multi-purpose functionality.

• IEC 60068-2-17 Environmental Testing - Part 2-17: Tests - Test Q: Sealing The core test method of this equipment is based on this standard, assessing the seal integrity of the relay housing by applying pressure (inflation/expansion).
• IEC 60255 Series Measuring Relays and Protective Devices For general electrical and safety specifications of relays (particularly protective relays), this equipment ensures that the relay still meets the requirements of this series of standards after environmental testing.
• ISO 16750-4 Road Vehicles - Environmental conditions and testing of electrical and electronic equipment - Part 4: Climatic Loads This equipment is used to verify whether the relay can withstand the climatic loads specified in this standard caused by pressure changes (such as altitude changes) and prevent moisture intrusion.
• GB/T 2423.21 Environmental Testing for Electrical and Electronic Products - Test Q: Sealing Corresponds to the Chinese National Standard IEC 60063-2-17.

• Airtightness Test: Determines whether the relay housing is properly sealed.
• Sealing Leak Detection: Precisely locates leak points or determines the total leakage rate.
• Inflation Pressure Withstand Test: Tests the relay's ability to maintain a seal under a specific positive pressure.
• Vacuum Retention Test: (i.e., venting) Tests the relay's sealing performance under negative pressure.
• Leakage Rate (L/min) Judgment: Quantitatively analyzes the degree of leakage in the relay.
