Corrosion-resistant stainless steel impeller with long service life

Abstract

The invention discloses a corrosion-resistant stainless steel impeller with a long service life. The stainless steel impeller comprises a base plate, blades and a cylinder, wherein the blades are welded to the top of the base plate at equal intervals, the cylinder is fixedly inserted in the middle of the base plate, retractable clamping devices are symmetrically arranged on the inner wall, close to the bottom, of the cylinder, a fixing device facilitating welding is slidably inserted in the cylinder, and an adjustable extrusion device is installed at the end, close to the fixing device, of the cylinder. Installation and detachment of a fixing column are facilitated. When the fixing column is clamped, a worker screws a threaded rod, the threaded rod extrudes a first extrusion block, a second sliding block slides in a sliding groove, meanwhile, the first extrusion block slides in a cavity along with the second sliding block, the first extrusion block extrudes a second extrusion block, then an extrusion plate extrudes the fixing column, and thus the clamping devices can clamp the fixing column more firmly. The stainless steel impeller can be easily installed and detached, and thus later maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of stainless steel impellers, in particular to a corrosion-resistant stainless steel impeller with long service life. Background technique [0002] A water pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, and suspoemulsions. And liquid metal, etc., can also transport liquid, gas mixture and liquid containing suspended solids. The water pump is mainly composed of pump casing, pump cover, pump shaft, impeller and sealing system. The impeller is an important part of the submersible pump and plays an important role in the work of the pump. [0003] The impeller of the existing water pump is composed of multiple identical blades, and the blades are uniformly fixed around the rotating s...

AI Technical Summary

Problems solved by technology

[0003] The impeller of the existing water pump is composed of multiple identical blades, and the blades are uniformly fixed around the rotating shaft. The blades can adopt different structural types according to the functional requirements, but when installing and disassembling the impeller, the traditional installation of the impeller is fixed by bolts and nuts. This method is too fixed, and it is not easy to disassemble, so that the installation and disassembly process becomes cumbersome and complicated, and wastes manpower
