Compatibility test

Test Background

Liquid cooling pumps are in long-term contact with coolant. The material compatibility and adaptability to low-viscosity media directly affect the pump's lifespan and performance. Bubble inhalation may cause cavitation damage.

Test Introduction

The compatibility test verifies the matching of the pump and the liquid cooling system through static corrosion tests of the coolant, adaptation tests of low-viscosity media, bubble-free operation tests, and communication protocol compatibility tests.

Testing Objectives

Verify the chemical compatibility between the pump body material and the coolant

Evaluate the adaptability of the pump to low-viscosity media (such as water)

Ensure the stable operation of the pump in a bubble-free state

Verify the communication compatibility with the CDU controller

FAQ
Q: Can ordinary water pumps be used with ethylene glycol solution? A: The viscosity of ethylene glycol is higher than that of water, which will lead to a decrease in head and efficiency. It is necessary to re-select the model or use it with a reduced rating, and it is also necessary to confirm the compatibility of the sealing materials.
