Tube expander technology principle
2019-01-19
Abstract:
The hydraulic expander used in the hydraulic expansion joint technology of domestic tube expander is composed of high-strength alloy steel core rod and high-pressure imported elastic rubber. It is designed in an integrated design and can withstand high pressure without the use of seals. It is easy to use and has high work efficiency. , the working principle is as shown:
Tube expander development background
2019-01-19
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
2019-01-19
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
2019-01-19
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.
Tube expander safety operation procedures
2019-01-19
Abstract:
1. Before the job 1.1 The power supply must be equipped with a leakage protector and is safe and reliable. 1.2 The working environment should be tight and dry. 1.3 When using flammable solvents, the container should be covered and must not be spilled.
