AI Technical Summary

Technical Problem

Existing hydraulic cylinder leakage detection devices cannot recover leaked oil, pollute the environment, and have low detection accuracy, making it difficult to accurately reflect the degree of seal failure.

Method used

Design a hydraulic cylinder leakage detection system, which adopts a built-in detection channel and resistance oil passage structure to convert minute leakage into a detectable pressure signal, and recovers the leaked oil through the return oil pipe. Combined with pressure sensor and PLC, it realizes real-time monitoring and quantitative analysis.

Benefits of technology

It enables timely detection of slow leaks, reduces environmental pollution and resource waste, improves detection accuracy and sensitivity, supports predictive maintenance, and reduces the risk of equipment downtime.
