High-frequency welded pipe equipment working principle
High-frequency welded pipe equipment is a kind of equipment that utilizes high-frequency electromagnetic field to melt and weld metal pipes, and its working principle mainly includes:
1. High-frequency power supply. The high-frequency generator in the equipment can produce a relatively high frequency current, generally in the range of 10kHz~500kHz, this current can excite the electrons and ions in the pipe, making it move faster and heat up.
2. Induction heating. High-frequency current is introduced into both ends of the pipe through the power regulator and the welding head, and the pipe itself generates high-frequency Eddy current through induction, which makes the pipe heat up extremely fast and reach the melting point to start melting the contact surface of the phase.
3. Automatic in and out frame. Used for pipe in and out and positioning, automatically advancing the pipe during the welding process, realizing continuous automatic production.
4. Inner and outer diameter setting. The inner and outer diameter measuring system is used to detect the pipe size and match with the preset welding process parameters, automatically adjusting the welding head movement trajectory to complete precise weld shaping.
5. Sealing and cooling system. Inside is an isolated space, completely sealed from the outside, and equipped with a cooling water system to protect the circuit system and cool the welding hot zone to ensure the stable operation of the equipment.
6. Process control system. All mechanical actions, welding parameters such as high frequency power, welding head moving speed, cooling water, etc. are controlled by microcomputer, through the human-machine interface to enter the process parameters to complete the high automation control.
High-frequency welded pipe equipment combined with the theory of electromagnetism, heat conduction, automatic control, etc., developed using microcomputer technology. Its main features are: high welding quality, high production efficiency, high degree of automation, wide range of applicable materials, long service life, mainly used for stainless steel, aluminum alloy, titanium alloy and high steel welding production, is an important equipment in the field of pipe connection.
Therefore, high-frequency welded pipe equipment with its unique working principle to realize high-quality, high-efficiency automated production, widely used in petrochemical, pipeline engineering, construction and decoration, energy and electricity, metallurgy and mining, machinery manufacturing and other fields, with an important role in promoting the development of related industries.
