How to deal with the burnout of the air conditioner compressor pile head, novices should use it with caution

The compressor is an important part of the air-conditioning equipment. Due to its large current, the temperature is sometimes low and sometimes high, which easily causes moisture adsorption. During maintenance, friends often encounter the phenomenon that the air conditioner compressor coil is normal, the socket piece of the pile head, and the pile head column rust, or even rust or even burn.

　　 1. If the compressor pile head is not rusty, but the inserts are broken, the simple method is to turn the three compressor lines around and use them, or to directly replace the inserts.

　　2. If the pile head of the compressor is rusty, polish the rusty place, plug in a new plug, put on a heat shrinkable tube or apply high-pressure glue or moisture-proof glue to prevent the rust from continuing.

3. If there are basically no compressor inserts, and three pillars are left, one way is to remove the copper pieces from the terminals in the 16A or so three holes, power plug, socket, and terminal block, pass the compressor line and then insert the compressor pile Head and then tighten the screws. Another method is to use 4-5 thick copper pipes with a length of 3-5 cm, one end cover of the terminal, and the other end of the compressor line to be crushed with sealing pliers.

　　4. If the compressor pile head is too short to achieve the above 3 methods, then the lead wire is welded out. For those skilled in welding, there is no need to let go of freon, and for novices, we must let go of fluorine. Before welding, remove the rust on the pile head, place the bucket at a high place near the compressor, use a small pipe to lead the water in the bucket to the base of the compressor pile head, heat the welding rod with solder powder and the pile head with a small fire, and it will be better ( Good toughness, it is difficult to break the imported silver brazing rod). Fold the 5 cm electrode by one centimeter and clamp the compressor line (each compressor line is covered with a heat shrinkable tube in advance), and clamp the middle flame with needle-nose pliers Weld up quickly and cool the electrode. After all three are welded, push down the heat shrink tube.

5. If the pile head has rusted to the base, one method is to saw off the top and replace the broken coil with the compressor. The top of the compressor is well welded, and one method is to replace the entire pile head of the compressor (but generally the glue connection is not strong enough, just Only a new compressor)
