The invention discloses a sealing performance test device and method for a superconducting motor refrigerant transmission sealing member, the test device comprises an inner cavity assembly, an outer cavity assembly and a plugging member, one end of the inner cavity assembly is provided with a first air vent, the other end is provided with a movable interface, and an inner radial spigot is formed on the outer wall of the inner cavity assembly at one end of the movable interface; the outer cavity assembly is coaxially arranged in the inner cavity assembly, one end, close to the movable connector, of the outer cavity assembly is provided with a second air vent, an outer radial spigot corresponding to the inner radial spigot is formed in the inner wall of the outer cavity assembly, and an inner ring and an outer ring of the sealing element to be tested are connected to the inner radial spigot and the outer radial spigot in a sealed mode respectively. Pressure measuring ports are formed in the outer wall, on two sides of the sealing element, of the outer cavity assembly, and an exhaust port is formed in the outer wall close to one side of the first ventilation port; the plugging piece is detachably arranged at the movable connector. The technical problems that an existing refrigerant transmission sealing performance testing device for the superconducting motor is too long in cooling time and complex in debugging process are solved.
