Test Procedures

Installation of Wash Rotor

Attach the automotive wash brush rotor to the rotation shaft of the test bench using specialized bolts.

Gap Adjustment

Adjust the vertical gap between the rotor edge and test platform to 100 mm using adjustment tools.

Preparation of Test Solution

Add the cleaning agent to the circulating water tank and ensure thorough mixing using the built-in agitator.

Sample Placement

Place test parts or sample panels on the work platform.

Trial Run

Perform a preliminary run to ensure correct operation, brush contact, and spray distribution.

Formal Testing

Run the programmed wash cycle, applying controlled brush and water motion to evaluate coating scratch resistance.

Maintenance Information

Clean brushes and work platform after each test.

Inspect spray nozzles for clogging and clean or replace as needed.

Regularly check water tank level and agitator function.

Ensure platform drive system and safety switches are operational.

Keep test chamber dry and free from residue after tests to maintain accuracy.
