Xiaoxiao popularization of science magnetron maintenance
Magnetron was successfully developed in 1936 and put into practical use in 1939. At present, every household cannot live without it. Is it possible for everyone in life? Can't find its existence, in fact, it has been in our lives. It is characterized by high power, high efficiency, small volume and low cost. It is essentially a diode placed in a constant magnetic field, in a tube? Electrons will interact under the action of mutually perpendicular constant electric fields, and the energy obtained by constant electric fields will be converted into microwave energy.

First, you have to find out that your magnetron is broken. Secondly, you will find this article in endless articles! Haha, just kidding. Ok, next, let's cut to the chase.

According to Bian Xiao, many defective magnetrons removed are short circuits of filament. After dismantling by the master, it was found that most of them were caused by the breakdown of the feedthrough capacitor of the tube seat. Know yourself and know yourself, and you will win every battle. We need to prepare the tools we need this time, okay? : screwdriver, pliers, wrench, scissors, 3.2mm diameter electric drill, hacksaw, small blade, 704 heat-resistant silica gel.

After we know the reason why it is broken, after we prepare the tools. The repair method provided by Bian Xiao is:

1. pry open its back cover. During this time, everyone should be careful not to be hurt by accidents.

2.? Cut off the connecting wire at the root of the socket.

3. Remove the four fixed blind rivets of the socket with a 3.2 mm diameter electric drill, and then remove the socket. At this point, our first step was successful.

4. Saw the circumference about 1mm deep along the thickness change with a hacksaw, and then open the kerf to see the breakdown point clearly.

5. Clean the carbon black at the infiltration place with a blade, and clean and dry it.

6. Cover with 704 heat-resistant silica gel, and shake the table after the gel dries.

7. The last step is to restore the magnetron in the reverse order of disassembly.

The above seven steps are the steps to repair the magnetron. Does it feel simple? Little friends, try it quickly.

Here, Bian Xiao will make up for the maintenance and reuse of magnetrons, which are usually used in microwave ovens. If the magnetron in the microwave oven is broken, most people will choose to replace it. Is this a waste? In fact, if the appearance of magnetron is relatively new, and the filament of two poles is 2 ohms, the fault is caused by short circuit, and it can be solved directly in two steps.

1. Open the rear cover;

2. Push the filament to about 5 mm, and then fix it with two-in-one glue.
