Description

Technical Field

[0001] The utility model relates to the technical field of self-balancing multi-stage pump casting processing, in particular to a clamping device for self-balancing multi-stage pump casting processing. Background Art

[0002] The self-balancing multi-stage pump is a power equipment used for transportation. It adopts advanced hydraulic models and independently develops high-efficiency and energy-saving products. Since the rotor of the self-balancing symmetrical multi-stage pump is free from the wear and axial pulsation of the balance disk, the alignment of the impeller and the guide vane is always in the best state. Unlike the ordinary multi-stage pump structure, the efficiency will not drop significantly due to the wear of the balance disk and the forward movement of the rotor components.

[0003] During the processing of self-balancing multi-stage pump castings, in order to facilitate the processing of the castings, a clamping device is usually used to clamp and fix the castings.

[0004] However, most of the current clamping devices for processing castings of general self-balancing multi-stage pumps lack a structure for disassembly and replacement when in use. Since different positions of the casting need to be processed, different positions of the casting need to be clamped, and clamping plates of different shapes need to be used. When the clamping plates cannot be disassembled and replaced, it is inconvenient to clamp different positions of the casting, which reduces the clamping effect of the casting. Utility Model Content
