The device includes a water tank, a first hydraulic cylinder, a movable plate, a rectangular frame, a second hydraulic cylinder, a sealing frame, a third hydraulic cylinder, a sealing plate, an air pump, and pipelines. The water tank holds clean water. The first hydraulic cylinder is installed on the outer wall of the water tank along its height direction and provides driving force to move along the height direction of the water tank. The movable plate is installed at the movable end of the first hydraulic cylinder, positioned above the water tank along its height direction, and moves up and down under the drive of the first hydraulic cylinder. The rectangular frame is connected to the movable plate and moves up and down under the drive of the movable plate. The slurry pump is placed on the bottom wall of the rectangular frame. The rectangular frame includes a drain outlet on its side wall to allow water to quickly immerse the slurry pump. The second hydraulic cylinder is installed on the top wall of the rectangular frame along the height direction of the water tank and provides driving force to move along the height direction of the water tank. The sealing frame is installed at the movable end of the second hydraulic cylinder and located inside the rectangular frame, moving up and down under the drive of the second hydraulic cylinder.

A third hydraulic cylinder is installed along the length of the water tank on the side wall of the rectangular frame. Along the height of the water tank, the third hydraulic cylinder is positioned above the moving plate to provide driving force for movement along the length of the water tank.

Controlling the second hydraulic cylinder moves the sealing frame until it contacts the slurry pump outlet, sealing the outlet. Controlling the third hydraulic cylinder moves the sealing plate until it contacts the slurry pump inlet, sealing the inlet and ensuring the pump's interior is completely sealed. Then, controlling the first hydraulic cylinder moves the moving plate, which in turn moves the rectangular frame until the slurry pump is fully submerged in water. Finally, the air pump delivers high-pressure gas to the pump's interior through a pipe. The presence of bubbles in the water indicates the pump's seal. Since none of the cylinders come into contact with water, waterproofing is not a concern, reducing production costs. Furthermore, because the slurry pump can be moved to the bottom of the tank, the amount of water required for complete immersion is reduced, conserving water resources.

The water tank 20 is used to hold clean water. The first hydraulic cylinder 30 is installed on the outer wall of the water tank 20 along its height direction, providing driving force to achieve the function of moving along the height direction of the water tank 20. The moving plate 40 is installed at the moving end of the first hydraulic cylinder 30, and is located above the water tank 20 along its height direction, moving up and down under the drive of the first hydraulic cylinder 30. The rectangular frame 50 is connected to the moving plate 40 and moves up and down under the drive of the moving plate 40. The slurry pump 10 is placed on the bottom wall of the rectangular frame 50. The rectangular frame 50 includes a drain outlet located on its side wall to allow water to quickly immerse the slurry pump 10. The second hydraulic cylinder 60 is installed on the top wall of the rectangular frame 50 along the height direction of the water tank 20, providing driving force to enable movement along the height direction of the water tank 20. The sealing frame 70 is installed at the moving end of the second hydraulic cylinder 60 and located inside the rectangular frame 50, moving up and down under the drive of the second hydraulic cylinder 60. The bottom wall of the sealing frame 70 seals the outlet of the slurry pump 10 to prevent air leakage. The third hydraulic cylinder 80 is installed on the side wall of the rectangular frame 50 along the length direction of the water tank 20, above the moving plate 40, providing driving force to enable movement along the length direction of the water tank 20. The sealing plate 90 is installed at the moving end of the third hydraulic cylinder 80 and located inside the rectangular frame 50, moving under the drive of the third hydraulic cylinder 80. The sealing plate 90 seals the inlet of the slurry pump 10 to prevent air leakage. An air pump 100 is installed on the top wall of the sealing frame 70 to provide high-pressure gas. A pipe 110 is installed at the outlet of the air pump 100 and passes through the bottom wall of the sealing frame 70 to transport high-pressure gas. The rectangular frame 50 moves into or out of the water tank 20 under the drive of the first hydraulic cylinder 30.

[0040] This embodiment of the invention provides a slurry pump 10 testing device. After placing the slurry pump 10 on the bottom wall of a rectangular frame 50, controlling the second hydraulic cylinder 60 moves the sealing frame 70 until it comes into contact with the outlet of the slurry pump 10, sealing the outlet. Controlling the third hydraulic cylinder 80 moves the sealing plate 90 until it comes into contact with the inlet of a slurry pump, sealing the inlet of the slurry pump 10, ultimately making the interior of the slurry pump 10 completely sealed. Then, controlling the first hydraulic cylinder 30 moves the moving plate 40, which in turn moves the rectangular frame 50 until the slurry pump 10 is completely submerged in water. Finally, controlling the air pump 100 delivers high-pressure gas to the interior of the slurry pump 10 through the pipe 110. Observing whether bubbles are generated in the water then determines the sealing performance of the slurry pump 10. Since none of the cylinders come into contact with water, there is no need to consider waterproofing performance, reducing production costs. Furthermore, since the slurry pump 10 can be moved to the bottom of the water tank 20, the amount of water required for the slurry pump 10 to be completely submerged is reduced, thus saving water resources.

The bottom plate 72 serves as the bottom wall of the sealing frame 70, sealing the outlet of the slurry pump 10. The support rod 73 is used to determine the relative position of the top plate 71 and the bottom plate 72, and to adjust the distance between the top plate 71 and the bottom plate 72, so that even if the slurry pump 10 is immersed in water, the air pump 100 will not come into contact with water.
