2023-06-29 09:50
High frequency welded pipe equipmentIt is a kind of equipment that uses high-frequency electromagnetic field to weld metal pipes. Its working principle mainly includes:
1. High frequency power supply. The high frequency generator in the device can generate a relatively high frequency current, generally in the range of 10kHz to 500kHz, which can excite the electrons and ions in the pipe, accelerate the movement speed and generate heat.
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 causes the pipe to heat up at an extreme speed, reaching the melting point and starting to melt the contact surface.
3. Automatic advance and retreat rack. It is used for pipe entry and exit and positioning, and automatically advances the pipe during the welding process to realize continuous automatic production.
4. Inner and outer diameter setting. The inner and outer diameter measurement system is used to detect the size of the pipe, match the preset welding process parameters, automatically adjust the motion trajectory of the welding head, and complete the accurate weld formation.
5. Sealing and cooling system. The 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 stable operation of the equipment.
6. Process control system. All mechanical actions and welding parameters such as high frequency power, welding head moving speed, cooling water volume, etc. are controlled by a microcomputer, and high automation control is completed by inputting process parameters through the man-machine interface.
High-frequency welded pipe equipment combined with electromagnetics, heat conduction, automatic control and other theories, the use of microcomputer technology developed. Its main features are: high welding quality, high production efficiency, high degree of automation, wide range of applicable materials, and long service life. It is mainly used for the welding of stainless steel, aluminum alloy, titanium alloy and high steel. It is an important equipment in the field of pipe connection.
Therefore, high-frequency welded pipe equipment with its unique working principle to achieve high-quality, high-efficiency automated production, widely used in petrochemical, pipeline engineering, building decoration, energy and power, metallurgy and mining, machinery manufacturing and other fields, with an important role in promoting the development of related industries.
