Tube expander development background
Abstract:
The tube expanding machine is mainly used for the connection between the heat exchange tube and the tube sheet. In the past, the heat exchange tube and the tube sheet mainly have several methods such as expansion joint, welding and expansion welding, and the expansion joint method can be divided into mechanical expansion joint and hydraulic expansion. Several methods, such as connection, rubber expansion and explosion expansion.

Pressure measurement and control and fault diagnosis of hydraulic tube expander
Abstract:
Pressure measurement and control and fault diagnosis of hydraulic tube expander Author: Yuan Zhaohui, Wu Zelong, Yan Huigeng Abstract analysis: The law and requirements of the pressure change of the hydraulic tube expander during the expansion process of the pipe provide a method for pressure fault diagnosis based on the control chart method. The PLC control system is used to realize the common six kinds of pressure fault diagnosis and display, and improve the hydraulic expansion. The reliability of the pipe machine in the heat exchanger manufacturing process.
Introduction to the working principle of the tube expander

Introduction to the working principle of the tube expander
Abstract:
The working principle of the tube expander is that when the motor rotates clockwise to drive the tube expander into the tube hole, because the expansion bead of the tube expander and the tube will produce a rotation angle, the tube expands the tube while rotating. The axis is forward, because the front of the tube expander is thick, so the rolling of the expanding beads will cause the tube to expand slowly and closely contact the wall of the tube sheet.
