Detailed Introduction

Hydraulic pump testing is a critical process to validate the performance of core power components in hydraulic systems, ensuring efficient and stable conversion of mechanical energy to hydraulic energy. Key tests include: 1. Performance Testing: Measuring flow rate, pressure, volumetric efficiency, and overall efficiency under rated conditions to verify output characteristics meet design standards; 2. Pressure Tolerance Testing: Conducting proof tests at 1.5x rated pressure to assess leak resistance and structural strength of the pump body and seals; 3. Durability and Fatigue Testing: Subjecting pumps to thousands of hours of continuous operation or alternating loads to evaluate wear and lifespan of moving parts like bearings, gears (or piston pairs); 4. Noise and Vibration Testing: Monitoring decibel levels and vibration amplitude at different speeds/loads to ensure stable operation and reduce resonance risks; 5. Contamination Resistance Testing: Running pumps with particle-contaminated oil to assess filtration capability and anti-wear performance. Primarily using bench tests with flow-pressure curve analysis, these tests ensure hydraulic pumps meet power output precision, energy efficiency, and long-term reliability requirements in applications like construction machinery and industrial machine tools.
