After the sealing is completed, the pressure plate 6 continues to move downward to make the motor housing 7 completely immersed in water and in a completely sealed condition. The pressure plate 6 also needs to be below the liquid level in the inner cavity of the water tank 4. At this time, the air pump 3 is started, and the air pump 3 outputs gas through the air pipe 31 and the inner tank 62, and is discharged from the exhaust hole 63 into the inside of the motor housing 7. When continuous bubbles appear in the water, it means that the motor housing 7 is leaking, otherwise it is qualified. The operation is simple and easy to operate. After the motor housing 7 is inspected, the hydraulic cylinder 2 will drive the pressure plate 6 to move upward. During the upward movement, the bottom plate 5 is subjected to the reaction force of the spring 41, so that the bottom plate 5 drives the motor housing 7 to move upward as a whole, so that the motor housing 7 automatically moves away from the water in the inner cavity of the water tank 4. When the motor housing 7 is completely out of water, the air outlet on the side wall of the air pipe 31 is aligned with the open groove 112 on the side wall of the sleeve 111, so that the gas output by the inflation pump 3 enters the outer groove 61 through the open groove 112, and is then discharged from the exhaust hole 63, so that the water droplets on the outer wall of the motor housing 7 are dried, and no manual drying or drying is required subsequently, thereby improving the practicality of the device.
