The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil, and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance transformation, isolation, voltage regulation (magnetic saturation transformer) and so on. According to the application, it can be divided into: power transformer and special transformer (electric furnace change, rectification change, power frequency test transformer, voltage regulator, mine change, audio transformer, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer , reactors, transformers, etc.).
Transformer recycling
There is a copper coil in the transformer, and the copper can be obtained by disassembling the transformer. The price of copper metal is relatively high, and the recovery transformer can sell the copper metal inside. Another use is for used transformers that have passed the service life but can continue to be used. Unscrupulous traders will recycle these used transformers and re-sell them with trademarks of well-known brands. Old transformer silicon steel sheets are also available for sale and are recycled by KG. It depends on the material of silicon steel sheet, the quantity, the quality, and the price. Generally in the 3 yuan - 6.5 yuan, KG, a large amount can be recycled at home. Even transformer oil can be sold.
The outer casing is usually reprocessed in a steelmaking furnace. There are also a number of current transformers inside. The main material coil and the silicon steel sheet can also be recycled. Therefore, after the transformer is retired, it is a treasure. After the large-scale transformer is recovered, the core, the silicon steel sheet, the copper wire and the like can be processed to manufacture a small transformer. The insulating oil can be reused after passing the inspection or filtering and dehumidification treatment. If the anti-fouling and creepage ratio are qualified, the casing can be reused. The tapping copper rod is also very valuable. Transformer recycling is mainly the material of the recovery transformer: the winding is copper wire, the price of copper is very expensive, can be directly used as raw material for copper smelting, the iron core is silicon steel sheet can be recycled as scrap steel, and the shell can also be recycled as scrap steel. . There is also oil for cooling, which can be recycled for industrial use after filtration and purification.
Piezoelectric Rings For Ultrasonic Machining
Ultrasonic processing is a special processing tool that uses ultrasonic frequency to vibrate at small amplitudes, and through the impact of the abrasive free of liquid between it and the workpiece on the processed surface, the surface of the workpiece material is gradually broken.
