Abstract

The invention discloses an automatic expansion joint system. A computer is integrated with a display control subsystem to store, display and print relative product information of a printing shell pipe type heat exchanger, expansion joint relative information, an expansion joint hole position image, and relative information of a pre-set expansion pipe machine servo control subsystem; and a pipe expansion machine expansion joint control subsystem and a pipe expansion machine servo control subsystem are controlled to move according to the expansion joint relative information and the relative information of the expansion pipe machine servo control subsystem. The invention also discloses an automatic expansion joint control method which comprises the following steps that: the computer is integrated with the display control subsystem to control the pipe expansion machine expansion joint control subsystem and the pipe expansion machine servo control subsystem to automatically carry out expansion joint, so that holes and heat exchange pipe bundles (which need to be subjected to the expansion joint) on the shell pipe type heat exchanger are jointed in an expansion manner. With the adoption of the system and the method disclosed by the invention, the manual operation is not needed, and the expansion joint quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to the field of manufacturing shell-and-tube heat exchangers, and more specifically relates to an automatic expansion joint system and an automatic expansion joint control method. Background technique [0002] With the increasingly stringent regulations on fluid temperature in the process of various heat transfer equipment, there are more and more heat exchangers on the market that are used to transfer part of the heat of the hot fluid to the cold fluid to make the fluid temperature meet the requirements of the process. At present, the most widely used shell and tube heat exchanger is composed of shell, heat exchange tube bundle, tube sheet, baffle (baffle) and tube box. [0003] At present, in the manufacture of shell-and-tube heat exchangers, it is more common to use strength expansion as the connection method between the tube sheet and the heat exchange tube bundle. The strength expansion joint refers to the expansion joint th...
