High frequency heat sealing machine equipment manufacturers, Qingdao Tianrun High Frequency (certified), high-frequency welding machine equipment provided by the Run High Frequency Electric Co., Ltd. Qingdao days. High Frequency Electric Co., Ltd. Qingdao Tianrun (www.gaozhoubo.com.cn) is specialized in "high frequency induction heating equipment, ultrasonic plastic welding machine, welding machine, laser cutting machine" of the enterprise, the company adhering to the "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Yan Lidong. 1, high-frequency and high-frequency current flow machine is made of circular or heating coil (usually with copper production) other shapes. Coil which produces instantaneous changes in the magnetic polarity of the beam, the metal is heated object is placed inside the coil, the magnetic flux will be heated through the entire body welding machine equipment, the object being heated inside the heating current in the opposite direction, there will be corresponding large eddy currents. Because of the heated object memory in the resistance, it will generate a lot of Joule heat, so the rapid rise in their body temperature. All metallic materials to achieve the purpose of heating. 2, in the high frequency machine by a unique set of electronic circuits, external power input comes from 50Hz low frequency alternating current into alternating current of high frequency above 20000Hz; after a high-frequency current to the coil, using electromagnetic induction principle is converted into a high-frequency magnetic field and a magnetic field acting on the metal object is; eddy current effect, generates a magnetic field proportional to the intensity of the induced current in the metal objects, the current flowing in the metal objects, it will by means of the inherent internal resistance value thermal effect generated by the current principles of heat, this heat is generated directly within the body, so the high frequency heat sealing machine equipment supply, this heating method, fast frequency heat sealing machine equipment features and high efficiency. If required, any metal material which can be melted in an instant. Moreover, it is the heating rate and temperature controlled. High frequency induction heating equipment has been widely used in the province of high frequency heat sealing machine equipment prices, set each frequency range 20}} - 450 kHz, high frequency power up to 400 kW. The province of high-frequency induction heating equipment is mainly used in metal heat treatment, 'quenching, diathermy, melting, brazing, straight seam welded steel pipe, vacuum devices to gas heating, semiconductor materials refining, plastic heat sealing, baking and purification, etc. . Now the high-frequency induction heating equipment used in the province are in high-power vacuum tube (launch tube) constitute the core of the single-stage self-excited oscillator converts the energy into high frequency alternating current high-voltage direct current energy, their conversion efficiency of the tube plate in general about 75 rings, the overall efficiency of the whole device is generally below 50 velvet, water and electricity consumption is very large.
