When the pump base 1 is clamped, the water inlet 12 is located on the outside of the cylinder 53, and then the pressure can be output through the cylinder 1 241 to make the pressure plate 242 located on the pump base 1, so as to lock the pump base 1 to prevent the pump base 1 from loosening.

[0039] Detection method 1: The rotation of cam 1 28 is controlled by motor 280.

[0040] Detection method 2: The gear 35 on the moving frame 3 is meshed with the rack 61 to control the translation of the U-shaped block 6, so that the detection frame 4 is located on both sides of the pump casing 11, and the screw 1 31 is rotated to drive the moving seat 33 and the U-shaped block 6 thereon to move vertically, and the detection position is moved vertically, and then the detection operation is performed, including adjusting the clamping claw 49 at the end of the push rod 46 to be close to the pump casing 11 by rotating the screw 2 45, so that the clamping claw 49 clamps the area outside the detection position of the pump casing 11 to locate the detection area, and then the motor 6 470 is used to drive the two cams 2 472 to rotate, and the two detection rods 48 are alternately moved, so that the detection head 482 at the end of the detection rod 48 performs a dynamic and static balance test on the pump casing 11 to detect the balancing effect of the pump casing 11 and its internal parts.

[0041] Detection method three: The thrust is outputted by cylinder three 51, so that the triangular block 57 moves up and down to drive the horizontal rod 58 to move horizontally. When the horizontal rod 58 moves toward the right-angle block 56, the conical surface 581 is slidably connected with the hypotenuse of the right-angle block 56, so that the moving rod 54 gradually slides toward the outside of the cylinder 53. Pressure is applied to the inner wall of the water inlet 12 by the moving rod 54, and the pressure and impact resistance of the inner wall of the water inlet 12 of the pump housing 11 are tested, so as to comprehensively test the performance of the large-flow flood control pump.
