Thermostat Aging Test Equipment 10 Independent Temperature Control Stations Full Temperature Range Accelerated Aging

Product Introduction

HH-WL-508 uses multi-station independent control and precise aging simulation technology to achieve efficient verification of thermostat performance:

▎10-station parallel aging system

• Independent measurement and control capabilities: 10 groups of independent stations run synchronously (5 upper stations + 5 lower stations), each group supports 0-999,999 cycle presets (resolution 1 time), suitable for all types of mechanical/electronic/intelligent thermostats, single device daily processing capacity reaches 2000+, and detection efficiency is improved by 70%.
• Quick clamping design: pneumatic push clamp (adjustable pressure 20-50N) completes thermostat positioning within 5 seconds (adaptive to φ15-φ50mm specifications), compatible with Midea, Haier and other brands of sudden jump and liquid expansion thermostats.

▎Full temperature range accelerated aging simulation

• Temperature control: independent hot air gun (heating rate 5℃/s) realizes 85℃ high temperature simulation, temperature uniformity ±1.5℃ (GB/T 2423.2 standard); side compressed air forced cooling (0.4-0.8MPa air pressure), -25℃ low temperature response time ≤30s, simulating the extreme working conditions of water heater dry burning protection.
• Cycle accuracy: test rate 1-10 times/minute adjustable (resolution 0.1 times/minute), precise control of heating-cooling-stop cycle (minimum cycle 6s), meeting IEC 60730Clause 15.3 action life test requirements.

▎Intelligent measurement and control and fault diagnosis

• Automatic judgment: industrial camera monitors the state of thermostat contacts in real time, automatically marks red alarm when trigger response time >5s or no action, computer system automatically judges qualification to avoid manual misjudgment (accuracy >99%).
• Data management: 128GB solid-state hard drive records 30+ parameters such as temperature curve, number of actions, response time, etc. of each workstation, generates CSV/PDF reports with timestamps (supports MES system docking), and the data traceability period is up to 10 years.

▎Safety and reliability design

• Hardware protection: Double-layer insulation cavity (surface temperature ≤45℃) with overload protection device, built-in leakage circuit breaker (response time <0.1s) and combustible gas sensor (only electronic thermostat test scenario), in line with EN 61010-1 electrical safety standard.
• Redundancy design: Automatic switching of main and standby gas sources (starting the standby pipeline when the gas pressure is <0.4MPa) ensures 7×24 hours of continuous aging without interruption, adapting to the needs of large-scale mass production sampling.

Product Features

• Multi-station parallel: 10 stations with independent counting and temperature control, support simultaneous testing of different models of thermostats, and adapt to the needs of small batch and multi-variety R&D.
• Extreme temperature range coverage: -25℃ low temperature start + 85℃ high temperature endurance test, covering the full scene application temperature of home appliances, meeting the temperature resistance requirements of GB 14536.1.
• Intelligent judgment: pneumatic clamping + visual recognition automatically judges eligibility, reduces manual intervention, and improves detection efficiency by 50% compared with traditional equipment.
• Accelerated aging: 10 times/minute high-frequency cycle test, 1 million life test cycle shortened to 72 hours, quickly expose early failure.
• Safety warning: fault sound and light alarm + automatic shutdown protection, real-time monitoring of 4 types of abnormalities such as contact adhesion and shell deformation, with a warning accuracy rate of >98%.
