Coated water pump impeller preparation method, impeller structure and application thereof

Abstract

The invention discloses a preparation method of a coated water pump impeller, an impeller structure and application of the impeller structure. A core body, cover plates and impeller blades are prepared through machining; a machining shaft rod provided with a mounting seat is sleeved with the core body, and the front cover plate and the rear cover plate are assembled; the machining shaft rod provided with the core body and the cover plates is installed on a machining table, and a servo motor drives the machining shaft rod to axially rotate on the machining table; a sliding block located in the machining shaft rod is driven to rotate, and the sliding block drives the mounting seat to move in the radial direction; feeding equipment on the machining table is controlled to feed the impeller blades, and the impeller blades are installed on the cover plates; and the water pump impeller is checked and accepted to complete machining, assembling and detection of the water pump impeller. Due to the fact that the core body is installed on the machining shaft rod in the process, the cover plates are driven to rotate through rotation of the shaft rod, and the core body and the cover plates are driven to move, after one impeller blade is installed, the next impeller blade is installed after the angle is rapidly adjusted, and therefore the machining efficiency is improved.

Description

technical field [0001] The invention relates to the field of preparation of coated water pump impellers, in particular to a preparation method of coated water pump impellers, an impeller structure and applications thereof. Background technique [0002] At present, the impeller is the core component of the water pump, so the quality of the impeller determines the quality of the centrifugal pump. It is driven by the motor to rotate, so that the medium is subjected to centrifugal force or lifting force, so that the medium has mechanical energy; its function is to directly transfer the mechanical energy of the prime mover It is passed to the liquid to increase the static pressure energy and kinetic energy of the liquid, mainly to increase the static pressure energy. [0003] At present, the casting impeller is the most used one. The production method is to die-cast the cover plate first, then process the impeller blade, and assemble the impeller blade and the cover plate through...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a coating water pump impeller preparation method, impeller structure and application thereof, aiming to solve the problem in the prior art that multiple impeller blades need to be installed during the assembly process of impeller blades and assembly parts, and many The first impeller blades are equidistantly arranged with the center of the cover plate as the axis center. Since the existing cover plate is fixed and the impeller blades are installed, it is necessary to repeat the cover plate during the installation process of multiple impeller blades. Disassembly, installation and adjustment, which will affect the processing efficiency
