Centrifugal pump rear panel disassembly device and disassembly method

Abstract

The invention discloses a disassembly and assembly device and a disassembly and assembly method for the back plate of a centrifugal pump. The disassembly and assembly device for the back plate of the centrifugal pump includes the back plate, which is provided with connection holes, and also includes: a support frame, which includes a support plate, a support plate and a limit plate connected in sequence, and the support plate and the limit plate Relatively set, the backing plate is located on one side of the back plate, the limit plate is set on the other side of the back plate after passing through the connection hole, and the support plate is penetrated in the connection hole; the bracket is the first end of the bracket Connected with the backing plate, the second end of the bracket extends in a direction away from the central axis of the connecting hole, and the second end of the bracket is provided with a hanging hole. The centrifugal pump rear panel removal method is used to remove and assemble the rear panel. The device and method for disassembling the back plate of the centrifugal pump provided by the present invention improve the safety of disassembling the back plate of the centrifugal pump, save the time required for disassembling the back plate of the centrifugal pump, reduce labor intensity, and reduce labor costs.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a device and method for disassembling and disassembling the back plate of a centrifugal pump. Background technique [0002] Centrifugal pumps, as a general-purpose machine, play an important role in the national economy and are widely used in industries such as electric power, metallurgy, coal, and building materials to transport various liquids or slurries containing solid particles. The back plate of the centrifugal pump is a wearable part, and the replacement cycle is 1-2 years. [0003] In the prior art, there is no special removal tool for the back plate of the centrifugal pump. When the back plate needs to be disassembled and replaced, it generally requires a number of workers to cooperate to disassemble the back plate from the centrifugal pump and replace the new back plate. Installed on a centrifugal pump. In the process of realizing the invention, the inve...

AI Technical Summary

Problems solved by technology

In the process of realizing the invention, the inventor found that the above-mentioned backboard has the following deficiencies in the disassembly process: first, after the backboard is disassembled, it needs to be hung to the work area through a hook, and the hook is directly hooked on the backboard , the weight of the backboard is relatively large and the surface is relatively smooth. During the hanging process, the backboard is easy to fall and injure the workers, and the safety is low; It is time-consuming, labor-intensive, labor-intensive and labor-intensive for the operator to lift the backboard to prevent the backboard from toppling over.
