Method for mounting side seal plates of drum strainer

Abstract

The invention provides a method for mounting side seal plates of a drum strainer in order to solve the problems of high construction difficulty, waste of manpower and material resources, low operation efficiency and high safety risk in use of mounting methods provided by manufacturers. The method includes: mounting the drum strainer in a pool with two side walls provided with pre-embedded plates, and measuring an axial end face runout value of a frame; subjecting a plurality of side seal plates to end-to-end welding to jointly form a side seal plate group connected to the frame, wherein the side seal plates are provided with fixing studs; turning the drum strainer to enable the side seal plate group to be rotated to a mounting position, welding the tail ends of the fixing studs to corresponding pre-embedded plates, and adjusting positions of the side seal plates; sequentially mounting other side seal plate groups, and integrally welding each two adjacent side seal plates; grouting for fixation. Using the method for mounting the side seal plates of the drum strainer is low in construction difficulty, convenient in quality detection and large in operation space and can shorten the construction period, save manpower and material resources and lower the risks.

Description

technical field [0001] The invention relates to a method for installing equipment in a nuclear power plant, in particular to a method for installing a side sealing plate of a drum-shaped filter screen. Background technique [0002] The seawater circulating water CRF system of the PX plant and the safety plant water SEC system each have 4 drum-shaped filters. The drum-shaped filter is the core equipment of the nuclear power plant circulating water filtration system. Its function is mainly to remove suspended particles larger than the mesh diameter in seawater. Dirt is one of the indispensable and important components of nuclear power plants. Such as figure 1 with figure 2 As shown, on the walls 13 on both sides of the pool 14 where each drum-shaped filter screen 1 is installed, there are as follows figure 2 The side sealing plate 3 of shown shape. [0003] The side sealing plate 3 is set in order to prevent the sealing rubber plates on both sides of the drum filter scre...
