Features
You test garments using a specially designed mannequin that simulates realistic human movement.
A waterproof turntable rotates at a constant speed to ensure uniform spray exposure.
The water supply system includes a pressure gauge and flow adjustment device for stable spray conditions.
Spray duration can be preset with automatic timing control.
A fully enclosed protection system surrounds the equipment to ensure laboratory safety.
A self-priming circulation hydraulic pump provides fast liquid supply with stable pressure.
The mannequin can perform leg lifting, arm swinging, and static postures during testing.
The control system and test chamber are separated to prevent contamination of electrical components.
A color touchscreen with menu-based operation ensures easy and intuitive control.
A 32-bit microcontroller-based multifunction control board ensures stable system performance.
Precision motor control allows accurate speed regulation and positioning.
Test Procedures
You dress the mannequin with the protective clothing to be tested.
Set spray parameters and test time via the touchscreen interface.
Start the test, and the turntable rotates while the spray system applies liquid to the garment.
The mannequin performs preset movements during spraying.
After the test, you inspect the inner surface of the garment to evaluate liquid penetration.
Maintenance Information
You should clean the spray system and circulation pipelines after each test.
Nozzles and flow meters should be checked regularly to ensure accurate spray conditions.
Mechanical moving parts should be inspected to maintain smooth operation.
Electrical components and seals should be checked periodically to ensure long-term reliability.
