Reliability and durability test

Test Background

The liquid-cooled pump needs to run continuously for a long time. Bearing wear, seal aging, and reduction of motor insulation are the main failure modes. Reliability verification is the key to ensuring the stable operation of the system throughout its service life.

Test Introduction

Through vibration and noise testing, continuous operation life testing, MTBF verification, dry-running protection and main-standby switching testing, simulate the reliability performance of the liquid-cooled pump under long-term operation and fault modes.

Testing Objectives

Verify the vibration and noise levels under rated operating conditions

Evaluate the continuous operation life and performance degradation

Ensure the reliability of the dry-running protection function

Verify the automatic switching ability of the main and standby pumps
