Description of intermediate frequency power supply for distribution of pipe fitting equipment

Intermediate frequency power supply is mainly used in the production of pipe fittings equipment, and in the production of pipe fittings, pipe fittings equipment will be distributed to the intermediate frequency power supply produced and processed by our company. The main use environment of intermediate frequency power supply is: The surrounding temperature can not exceed more than 40 degrees Celsius, can use the medium frequency power within 24 hours of the temperature can not exceed 35 degrees Celsius, can not be lower than the environment temperature of 5 degrees Celsius, generally ordered the company's production of pipe fittings equipment mainly can produce a variety of models of pipe products. With the intermediate frequency power supply, the pipe fitting equipment has the advantages of simple operation, high production efficiency and long service life. The function of the medium frequency power supply of the device is to cool the water back and forth. The cooling water should be transparent, not turbidity, not precipitation, and the water quality is in line with the use of pipe fitting equipment.

The basic principle of medium frequency power supply: mainly used in all kinds of metal melting, heat preservation, sintering, welding, quenching, tempering, dithermic, liquid metal purification, heat treatment, bending pipe, and crystal growth.

The standard output power series is 30kW to 4000kW

Standard configuration melting furnace series: 5kg(30kW)~5000kg(4000kW)

The standard oscillation frequency series is 400Hz~10kHz

Medium frequency induction heating technology is to heat the workpiece by electromagnetic induction principle and eddy current. Induction heating has a series of advantages such as fast heating speed, high internal heating efficiency of materials, uniform heating and selectivity, good product quality, almost no environmental pollution, good controllability and easy to realize production automation, so it has been rapidly developed in recent years. At present, induction heating has been widely used in casting and melting, forging blank heating, metal surface heat treatment, aluminum electrolysis and other industries. Above these industries in the traditional heating methods mostly based on coal, oil, gas as energy or electric furnace heating, there are high energy consumption, poor labor conditions, environmental pollution, serious technology quality is difficult to control defects, seriously restricted the development of our equipment manufacturing industry. Therefore, to popularize induction heating technology is the inevitable trend of transforming the traditional industry, and the development of this technology is closely related to the level of induction heating power supply.

The three-phase bridge fully controlled rectifier circuit is used to rectify the alternating current into direct current. After passing through the reactor flat wave, it becomes the DC power supply. Then through the single-phase inverter bridge, the DC current is inverted into the single-phase intermediate frequency current of a certain frequency (generally 1000 to 8000Hz). The load consists of an induction coil and a compensating capacitor, which are connected into a parallel resonant circuit (or in series. Generally, IGBT power supply adopts series resonance, of course, IGBT power supply can also adopt parallel resonance).
