ASTM D2809 Engine Coolant Aluminum Pump Cavitation Corrosion Characteristics Tester

Engine Coolant Aluminum Pump Cavitation Corrosion Characteristics Tester

The Engine Coolant Aluminum Pump Cavitation Corrosion Characteristics Tester, which meets the ASTM D2809 standard, is a highly specialized laboratory equipment with extremely strict parameter control. It quantitatively evaluates the ability of the coolant to protect aluminum components from cavitation corrosion by accurately simulating the operating environment of the engine water pump under specific harsh conditions. This test result is one of the core indicators for evaluating the performance of an engine coolant, especially for modern high-power density engines.

Principle:

The Engine Coolant Aluminum Pump Cavitation Corrosion Characteristics tester simulates the high temperature and high pressure environment of the engine cooling system, causing the aluminum pump to operate at high speed in the coolant, resulting in cavitation. The local high pressure and high temperature during the rupture of air pockets can accelerate the corrosion of aluminum surfaces. After a period of continuous testing, the corrosion level of the pump body (such as quality loss and surface damage) is evaluated to assess the corrosion resistance of the coolant.
