Product Description

200KW all solid-state high frequency finned tube welding power supply and welding forming mechanism


All-solid-state induction heating power supply refers to induction heating power supply with various power transistors, such as MOSFET, IGBT and other power devices, also called modern induction heating power supply. The "solid state" induction heating power supply is for the old-fashioned thyristor and vacuum tube induction heating power supply. It has the advantages of small power supply, low loss, high inverter conversion efficiency, easy operation and control, and safety.


The all-solid-state high-frequency finned tube welding power supply is a device that uses the all-solid-state high-frequency heating power supply for the welding of high-frequency spiral finned tubes. Using the principle of high-frequency contact welding, the steel strip wound on the outside of the steel pipe and the outer surface of the steel pipe are firmly welded together to produce high-frequency spiral finned pipe products, which are used in the manufacture and production of boilers and heat exchangers.


Our company started the development and research work of all solid-state high-frequency heating power for high-frequency spiral finned tubes several years ago, and achieved success.


Due to market and technical reliability reasons, our company has not yet promoted the application of this product on a large scale. But our company has not given up on the continuous improvement and enhancement of this product. At present, our company has developed the second generation of all-solid-state high-frequency welding power source for high-frequency spiral fin tube welding based on the respective technical characteristics of similar products at home and abroad. Its performance and technical reliability and equipment control have been significantly improved, the technology is more advanced, the performance is more stable, the operation is more convenient and intelligent, and the maintenance is easier. Ensure that users can produce qualified finned tube products with energy saving, high efficiency and high quality.

 

Main technical parameters of all solid-state high frequency spiral finned tube welding power supply

 

Main technical performance

1. The unique frequency tracking and control technology is adopted to make the inverter switching power devices always work in the state of zero voltage switching ZVS and zero current switching ZCS. The inverter has high power factor, low switching loss, high efficiency, and power. The life of the device is prolonged and the failure rate is low.


2. The double closed-loop control method of voltage and current feedback is adopted to make the output power constant during the welding process of the finned tube, thereby ensuring the consistency of the welding quality.


3. The oscillation frequency is high, the oscillation frequency is about 350-400KHZ, and the output waveform is sine wave. The current density and current uniformity of the contact surface between the fin and the steel tube are increased, the contact part is melted quickly, and the fusion rate and welding fastness of the fin tube are improved. The welding quality of the finned tube is guaranteed, and the yield is high.


4. In the special design of the control circuit, this equipment has a fixed fault tolerance function, that is, due to the rust removal of the steel tube, the irregular roundness and the burr of the steel strip appear instantaneous open circuit and hit during the welding process of the fin tube. In the event of fire, the equipment can maintain normal operation without shutting down. Reduce the number of stoppages caused by false fault bows, and ensure that the number of welded breakpoint joints of the entire fin tube remains within the range specified by the national standard for fin tube. This is a significant technical function of this device.


5. It has the function of belt break protection. When the steel belt is broken, it can automatically stop the power output, and at the same time output a control signal to automatically stop the dragging equipment.


6. This equipment adopts the split structure form of the main cabinet and the high-frequency output unit, and the volume of the high-frequency output unit is much smaller than that of the current solid-state high-frequency power supply of high-frequency welded pipes that is used for welding finned tubes. Volume, so that when the original electronic tube high-frequency welding power supply is replaced with a solid-state high-frequency welding power supply, the mechanical parts of the original fin tube production line remain unchanged, especially the welding head can remain unchanged. The renewal and transformation of the high-frequency welding power source is simpler, easier, and more cost-effective. As shown in the picture of the device.


7. A large number of digital integrated circuits and application-specific integrated circuits are used in control circuits and protection circuits, which simplifies the design of the circuit and improves the reliability of the system.


8. High conversion efficiency and obvious energy saving. The load power factor of the transistor inverter can be close to 1. And there is no power loss of transformers, filament regulators and electron tubes. It also reduces the amount of cooling water.


9. There is no high voltage inside and at the output end of the power supply, and the safety is high. 9. The equipment protection circuit is perfect and the reliability is high.


10. The whole equipment has a compact structure, no transformer, and a small footprint.


11. This equipment is a high-frequency welding power source specially used for finned tubes, which is produced and developed by our company based on the welding technology of finned tube equipment and years of experience in debugging and maintenance. Available for finned tubes made of carbon steel, stainless steel, alloy steel and other materials.
