Welding equipment for rotating wheel assembly of full-tubular pump

Abstract

The invention discloses welding equipment for a rotating wheel assembly of a full-tubular pump. The welding equipment comprises a bottom frame and the rotating wheel assembly. Supporting plates are arranged at the two ends of the top of the bottom frame respectively. The rotating wheel assembly is arranged at the tops of the two supporting plates. Three supporting plates are arranged on the top face of the part, between the two supporting plates, of the bottom frame. A second fixed block is fixedly arranged at the bottom of the side wall of one side of the bottom frame. A second hydraulic cylinder is arranged at the top of the second fixed block. Before welding, an upper hoop plate and a lower hoop plate are mounted on the outer circle of the rotating wheel assembly, hanger plates at the two ends of the upper hoop plate and the lower hoop plate are fixed together through bolts, welding is started, and a gap is generated when the rotating wheel assembly deforms in the welding process; by additionally arranging a cushion block, the outer circle of the rotating wheel assembly in the welding process is controlled, and therefore the welding deformation of an impeller assembly is ensuredto be effectively controlled, the design is more accurate, the welding process is faster, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of processing equipment for full-through-flow pump runner components, in particular to a welding equipment for full-through-flow pump runner components. Background technique [0002] Tubular flow pump is a type of horizontal axial flow pump. It is composed of a motor, a deceleration device and a water pump. It is installed in the machine pit inside the underwater dam. The water inlet and outlet channels are located on a straight line, which is approximately straight cylindrical, with less hydraulic loss, high water lifting efficiency, and compact structure. The installation and maintenance are convenient, and the pumping station project is simple. [0003] At present, the welding deformation of the runner assembly is huge during the welding process, which leads to the need to increase the design allowance before welding, the inability to continuously weld during the welding process, and the large amount of processing...

Problems solved by technology

[0004] The purpose of the present invention is to provide a welding equipment for the runner assembly of a full-through flow pump to solve the problem that the welding deformation of the current runner assembly is huge during the welding process, which leads to the need to increase the design margin before welding, and the continuous welding cannot be performed during the welding process. The production efficiency is very low due to the large amount of post-processing; and the existing welding equipment cannot adjust the position of the runner assembly during the welding process, which is not convenient for the multi-directional welding work of the runner assembly
