Abstract
A constant value method for detecting and evaluating internal leakage in a hydraulic cylinder and a detection device. The method comprises: step (1) measuring an accurate pressure drop value Δp of the internal leakage in the hydraulic cylinder; step (2), determining whether the detected hydraulic cylinder meets a standard: if the product of the accurate pressure drop value Δp of the internal leakage in the hydraulic cylinder and a corresponding hydraulic stroke L, is less than a standard parameter C for evaluating the internal leakage in the hydraulic cylinder, the internal leakage in me hydraulic cylinder meets the standard. Otherwise, the internal leakage in the hydraulic cylinder does not meet the standard. The detection device comprises a motor, a hydraulic pump, a directional valve, a detected part, a pipeline disassembly joint and a pressure sensor.
