The utility model discloses a simulation and detection system for conditions in dairy food acquisition, and aims to provide a simulation and detection system for conditions in dairy food acquisition to allow for reduction of labor intensity, reduction of breast disease incidence and high accuracy of testing data. The simulation and detection system for conditions in dairy food acquisition comprises a vacuum system, a milking system, an online test telemetering system for performance of the vacuum system, a testing system for an automatic milking volume metering device, a cup-drop lifting power testing system, a pulsating performance tester and a master digital simulation-detection system, wherein the vacuum system is composed of a vacuum pump, a vacuum pressure-stabilized tank, a vacuum adjuster, a vacuum pressure meter and a vacuum pipeline, and the milking system is composed of a collection metering tank, an automatic metering tank, a collection and input pipe, a metering and input pipe, an electric pulsator, a milk check valve, a milking cup set, an automatic-drop pull cord, a vacuum cylinder and a drain valve for the collection metering tank. The simulation and detection system for conditions in dairy food acquisition is applicable to laboratory simulated condition detection or factory online detection for milking system equipment.
