[0019] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0020] like Figure 1-Figure 5As shown, this embodiment provides a blade for a high-efficiency stamping centrifugal submersible pump with a single-stage high head, comprising an upper cover 1, a lower cover 2, and an impeller 3. The impeller 3 is mounted between the upper cover 1 and the lower cover 2. The impeller 3 comprises a first mounting plate 4, a second mounting plate 5, and a plurality of blades 6. The plurality of blades 6 are mounted equidistantly between the first mounting plate 4 and the second mounting plate 5. The first mounting plate 4 is detachably connected to the upper cover 1, and the second mounting plate 5 is detachably connected to the lower cover 2. Specifically, the upper and lower ends of the blades 6 are respectively provided with plugs 7. The first mounting plate 4 and the second mounting plate 5 are provided with sockets 8 that match the plugs 7, and the plugs 7 are placed in the sockets 8. By first combining the blades 6 with the first mounting plate 4 and the second mounting plate 5 to form the impeller 3, and then combining the impeller 3 with the upper cover 1 and the lower cover 2 to form a complete blade 6, when replacement is required, the upper cover 1 can be opened and the damaged blade 6 between the first mounting plate 4 and the second mounting plate 5 can be removed for replacement, thereby achieving convenient replacement and disassembly.
