Tool for inspecting filter element replacement system and use method of tool

Abstract

The invention belongs to the technical field of nuclear power station construction, and provides a tool for inspecting a filter element replacement system in order to solve the problem that a current filter element replacement system is low in inspection efficiency and high in inspection cost. The tool comprises an inspecting board, a first pin and a second pin, a clamp groove, a first pin hole and two second pin holes are formed in the inspecting board, the positions of the clamp groove, the first pin hole and the second pin holes are set according to the design requirement of position relationships of rails of the filter element replacement system, an index plate mounting hole and a filter element mounting hole, the first pin is inserted into the first pin hole in inspection, and the second pin is inserted into the second pin hole. By the aid of the tool, the inspection efficiency of the filter element replacement system is improved, and the inspection cost of the filter element replacement system is reduced.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant construction, and in particular relates to a tool for checking and accepting a filter element replacement system, and also relates to a method for using the tool for checking and accepting a filter element replacement system. Background technique [0002] The filter replacement system is a unique design of the EPR nuclear power plant (the third generation nuclear power plant). figure 1 Schematic top view of the track and filter frame for the filter replacement system, such as figure 1 As shown, the filter frame 10 is a cylindrical structure, the fixed plate 13 is fixed on both sides of the filter frame 10, the crossties 12 are fixed on the fixed plate 13, the rails 11 are fixed on the crossties 12, and there are several filter filters between the rails 11. Filter frame 10, only one is shown in the figure; Two filter element mounting holes 14 are symmetrically arranged on the filter fr...
