Shell-and-tube heat exchanger manufacturing and machining method

Abstract

The invention provides a shell-and-tube heat exchanger manufacturing and machining method which involves a clamping mechanism, a regulation and control mechanism, bottom support mechanisms, a bottom plate and a ring stand vertical plate. The method solves the problems that when a heat transfer tube bundle is installed at present, tube plates at the two ends are clamped and fixed through clamps, then the spacing position of baffle plates is moved and fixed, and finally, the heat transfer tube bundle is inserted into the tube plates and the baffle plates; in the mode, manual operation is tedious, flexible and adjustable fixing clamps are not arranged to assist in the insertion process of the heat transfer tube bundle, the efficiency of the whole operation process is reduced, and large-scale production operation cannot be achieved; and the clamps can only clamp and fix the tube plates and the baffle plates with specified sizes, flexible adjustment cannot be achieved, and market requirements cannot be met.

Description

Technical field [0001] The present invention relates to the field of heat exchange equipment, and more particularly to a method for fabricating a shell-type heat exchanger. Background technique [0002] The housing heat exchanger consists of a housing, a heat transfer tube bundle, a tube plate, a folding plate, and a tube box. The housing is mostly a cylindrical shape, and the inner is equipped with a tube bundle, and there is a plurality of folding plates between the tube sheets, and the panel plate can improve the cassette fluid speed, forcing fluid to specify more. The secondary transverse passes through the tube bundle and enhances the degree of fluid turbulence; [0003] Today, the heat transfer tube is fixed at the time of installation, and then moves the tube plates at both ends at the time of installation, and then moves the discharge pitch position, and finally insert the heat transfer tube bundle into the tube plate and the baffle, this manner is cumbersome There is no ...

AI Technical Summary

Problems solved by technology

[0003] At present, when the heat transfer tube bundle is installed, the tube sheets at both ends are clamped and fixed by clamps, and then the distance between the baffles is moved and fixed, and finally the heat transfer tube bundle is inserted into the tube sheet and the baffles. This method is cumbersome through manual operation. , there is no flexible and adjustable fixing fixture to assist the insertion process of the heat transfer tube bundle, which reduces the efficiency of the entire operation process and cannot be mass-produced, and the fixture can only clamp and fix the tube sheet and baffle of the specified size, and cannot Flexible adjustment to meet market demand; therefore, the present invention provides a method for manufacturing and processing a shell-and-tube heat exchanger
