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.
