Detailed Introduction

Hydraulic cylinder testing is a critical process to validate the performance of core actuator components in hydraulic systems, ensuring reliable power output and stability under high-pressure conditions. Key tests include: 1. Pressure Sealing Test: Detecting leakage from the cylinder body, piston, and seals under rated pressure and 1.5x proof pressure to ensure no external/internal leaks; 2. Performance Testing: Verifying piston stroke accuracy, motion smoothness (e.g., creep resistance), and rated thrust/tensile force output; 3. Durability Testing: Subjecting cylinders to millions of reciprocating cycles to assess seal wear, rod coating corrosion resistance, and cylinder fatigue life; 4. Cushioning Performance Test: Simulating start-stop impacts to evaluate the buffer device’s ability to reduce vibration and noise. Methods include bench static loading, dynamic condition simulation, and leak visualization, ensuring hydraulic cylinders meet pressure-bearing capacity, motion precision, and long-term reliability requirements in construction machinery, industrial equipment, and other applications—an essential guarantee for hydraulic system safety.
