The magnetron consists of a die and a magnetic steel. The structure of the die includes four parts: anode, cathode, energy output device, and magnetic circuit system. The inside of the pipe maintains a high vacuum state. In popular terms, the electrons in the tube are controlled by a constant magnetic field and an electric field perpendicular to each other, and interact with the high-frequency electromagnetic field, so that the energy obtained in the constant electric field is converted into microwave energy. What is the working principle of magnetron? Magnetron prices are expensive?
〠Magnetron working principle 】
In the magnetic wave field of the interaction space, as it decays exponentially away from the anode surface, the microwave field at the cathode surface becomes weaker, the grouping of electrons becomes smaller, and no obvious electronic spokes are formed in the vicinity thereof, but form. Almost evenly distributed electronic hubs. Most of the electrons in the interaction space of the magnetron are favorable electrons. During the process of moving towards the anode, it takes a long time for favorable electron revolving, and it can fully convert the DC potential into microwave energy. On the contrary, the number of electrons moving at the cathode is less, and the ability to absorb from the microwave field is also less. .
[Magnetron Anode Resonance System Function]
The anodic resonance system consists of a set of closed resonant cavities arranged along the circumference. Magnetrons, as oscillators, require a certain amount of energy storage to maintain microwave oscillations and thus require a high quality factor in the anodic resonant system. At the same time, in the magnetron, the oscillating energy needs to be output through the output device before it can be used. Therefore, the design of the energy coupling element on the anode resonant system is very important. It needs to couple a certain amount of energy to ensure the use, but also to make the anode resonant system have a higher quality factor, to maintain a sufficiently high energy storage, and to maintain the stability of the magnetron. The magnetron works in the mold. In order to ensure the stable operation of the mold, there should be a good mode partition between the adjacent mold and the mold. Therefore, an anode resonance system with a diaphragm belt or a sunburst type is often used.
ã€Magnetic price is not expensive】
The wide application of magnetrons, their prices are ups and downs. The deciding factor is that its demand is also its value. According to the data compiled by Xiao Bian, the most expensive magnetron is the price of CKM-204 pulsed magnetron at 16,000; the price of JRCM1475AX-BandMagnetron radar magnetron 25KW radar magnetron 25KW is 5500; NJRC produced in Japan The 25kw radar magnetron has a price of 4850 in the market. This is followed by a magnetron of Japan's NJRC marine 10kw radar produced in Japan, which has a market price of 3,150. Hitachi microwave oven MRO-A5000c magnetron, the market price of 850. The above three are all relatively expensive and are of special use.
The most widely used magnetron is in the microwave industry. The more expensive industrial microwaves are Samsung's OM75P(31), which has a price of 230 and Panasonic's 2M261-2, and the market price is also 230. Microwaves for home use 2M210-M1 produced by Panasonic and Samsung produced 2M167B-M11 is more expensive, the market price is 215, followed by the production of M24FB-610A, the market price of 214.
Xiao Bian concludes: The above introduced magnetron prices for everyone and hopes to help everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.
