Content

The Expansion Tank Static Pressure Test Machine is a specialized system designed to evaluate the static pressure performance and leak resistance of automotive expansion tanks. You can adjust the static pressure from 0 up to a maximum of 5 bar, while controlling the flow rate of each sample from 0 to 8 liters per hour. The system includes indirect chamber heating for safety (Explosion Protection Level 1), automatic leak detection, and fail-safe shutdown of defective samples, providing a reliable and efficient solution for expansion tank testing.

Application

The Expansion Tank Static Pressure Test Machine is suitable for a variety of automotive component testing applications:

Expansion Tanks: Evaluate static pressure resistance, leakage, and functional performance.

Coolant System Components: Test caps, valves, and connectors under controlled static pressure.

Material Durability Testing: Assess long-term reliability of plastic, metal, and composite tank materials.

Quality Control: Ensure compliance with OEM and supplier specifications for automotive cooling systems.

R&D and Certification Testing: Support component development, validation, and system integration.

Typical test products include automotive expansion tanks, coolant reservoir tanks, and associated components requiring static pressure evaluation.

Standards

The system supports compliance with major automotive engineering standards:

VW TL889 (4.1) – Volkswagen Group technical specification for interior and related component functional performance.

ESDG93-8A080-AA (3.6) – Ford engineering specification for component functionality and reliability.

GMW15310 (3.2.1.2) – General Motors global standard for material and component performance testing.

QV17004D (3.2.6) – BMW group specification for system component functionality and durability.

Test Procedures

Ensure the test area is clear and safe for operation.

Connect the system to the 9.5 kW power supply.

Fill the chamber and sample lines with glycol/water mixture.

Mount expansion tank samples in the test chamber.

Set the static pressure (0–5 bar) and flow rate (0–8 l/h) for each sample.

Activate the test system and indirect heating if required.

Monitor pressure, flow, and leak detection sensors throughout the test.

Automatically shut down any failed samples.

Record all test results for quality control or validation purposes.

After testing, safely drain the medium and allow the system to cool before removing samples.

Maintenance Information

Inspect sample mounting brackets, pressure sensors, and leak detection units before each test.

Verify flow control devices and chamber seals for proper operation.

Periodically calibrate pressure sensors and temperature controllers.

Clean the chamber and fluid circuits to prevent contamination.

Replace worn or defective components to maintain safe and accurate operation.
