In order to make the pump better, the ends of the upper blade 12 and the lower blade 13 that are not connected by the compression spring 14 are in contact with the inner wall of the pump body 10, and at the same time the upper blade 12 and the lower blade 13. The hole 1-1 is movable. The inlet pipe 23 and the outlet pipe 22 are arranged on both sides of the pump body 10 and are vertically arranged with the mandrel 1. The lower side of the pump body 1 is provided with a bottom plate 26.

In order to make the connection between the mandrel 1 and the pump body 10 more tightened and to facilitate the fixing of the mandrel 1, a front gland 3 can be provided on one side of the connection between the mandrel 1 and the pump body 10, and the mandrel 1 and the pump The other side of the connection of the body 10 can be provided with a rear gland 20. Both the front gland 3 and the rear gland 20 are connected to the pump body 10. The input end of the mandrel 1 is provided with a connection key 2, which can facilitate the connection of the power output device with the pump body 10. Spindle 1 is connected. In order to make the connection between the pump body 10 and the mandrel 1 more tightly, and also to obtain a better sealing effect, a first O-type rubber ring 4 may be provided on the axial outer side of the first bearing 5, and the first O-type rubber ring 4 can be arranged in the front gland 3, the axial inner side of the first bearing 5 can be sequentially provided with a second O-ring 6, a first stop ring 7 and a first moving ring 9, a first stop ring 7 and a first The end face formed by the moving ring 9 prevents the liquid from entering, so that the sealing effect is better.

In a new type of crocodile pump of this embodiment, when the crocodile pump is working, the rotation of the mandrel 1 drives the upper blade 12 and the lower blade 13 to rotate, and the upper blade 12 and the lower blade 13 are driven by the mandrel 1 in the cylinder body, In fact, the eccentric rotation is performed. The upper blade 12 and the lower blade 13 are connected by the compression spring 14 and can move in the through hole 1-1 of the mandrel 1. The upper blade 12 and the lower blade 13 are driven by the mandrel 1. The action of the compression spring 14 will automatically adjust the length of the extension from the mandrel 1 , and the end of the upper blade 12 and the lower blade 13 not connected by the compression spring 14 will always keep in contact with the inner wall of the pump body 10 . When working, as shown in Figure 3, the mandrel rotates clockwise, and the cavity formed by the water inlet end of the cylinder and the upper blade 12 and the lower blade 13 increases from small to large to increase the water absorption, and the water is sucked in, and the water is discharged from the cylinder. The cavity formed by the end and the upper blade 12 and the lower blade 13 changes from large to small to reduce the amount of water. Through the rotation of the mandrel 1, the upper blade 12 and the lower blade 13 are rotated to squeeze the water suction chamber, and the water is squeezed out to achieve water absorption. After the purpose of drainage, and the other drainage chamber is emptied, the cavity changes from small to large, and the pressure in the cavity is lower than the external atmospheric pressure, so that water is sucked in. The upper blade 12 and the lower blade 13 are in the pump body 10. The two cavities formed inside will always have one absorbing water and the other draining water, so as to achieve the purpose of continuously absorbing and draining water. In addition, the pump can be reversed. The reverse is mainly when there is debris in the water pipe. It can be reversed to push out the debris in the tube, thereby improving work efficiency. The alligator pump can replace any kind of centrifugal pump and other plunger pumps. In addition, the alligator pump has strong self-priming ability, high pressure, high lift, large flow, high efficiency, long service life and low wear.
