Three kinds of internal leakage detection method for hydraulic cylinder were analyzed and compared. The differential pressure method was proposed to detect internal leakage. The detection principle and system components of the differential pressure method were described. Compared with the previous three detection methods, the differential pressure method has the characteristics of high precision and high degree of automation.
