The Coolant Pulsation Testing Machine is a precision testing system designed to evaluate automotive cooling components under dynamic pressure conditions. You can use it to test radiators, rubber hoses, expansion tanks, and other cooling system parts for durability, leakage, and functional performance. The front-and-rear dual-door design allows easy installation and removal of samples, while the system automatically detects leaks and shuts down failed samples to ensure safe, reliable operation.
Application
The Coolant Pulsation Testing Machine is suitable for a wide range of automotive testing applications:
Radiator Testing: Evaluate structural integrity and leak resistance under pulsating pressure and thermal load.
Rubber Hose Testing: Test durability, pressure pulsation resistance, and functional lifespan of coolant hoses, including aramid-reinforced hoses.
Expansion Tank Testing: Verify thermal stability and mechanical durability under dynamic coolant flow.
Component Validation: Conduct system-level verification for cooling components before vehicle integration.
Automotive R&D: Support material selection, design optimization, and durability assessment of cooling systems.
Typical test products include radiators, coolant hoses, expansion tanks, thermoplastic and composite cooling system components.
