The invention discloses an air medium detection method and detection device for a blade type variable displacement oil pump. The detection method comprises the steps of 1, establishing a gas detectionstandard of the blade type variable displacement oil pump, and 2, performing torque detection, vacuum degree detection, yaw flexibility detection, safety valve opening pressure detection, oil pump flow detection and leakage detection on the blade type variable displacement oil pump correspondingly. According to the working principle of the blade type variable displacement oil pump, the method that oil pressure detection is replaced with an air medium is adopted, and the detection method and device based on the air medium are provided, so that the torque detection, the vacuum degree detection,the yaw flexibility detection, the safety valve opening pressure detection, the oil pump flow detection and the leakage detection are realized. The detection method not only is environment-friendly and clean, but also saves t
