Air-conditioning compressor wiring tips 1. Normally, for the air conditioner compressors of different manufacturers, the positions of the terminals of each of them are different, but there will be letters next to the terminals. For single-phase compressors, C represents the common terminal, R represents the main winding terminal, and S represents the secondary winding terminal. The wiring of each winding must be as shown in the figure, otherwise the compressor will not work properly or even burn out. 2.Let's understand the determination method of the three end positions of the single-phase compressor. First, its main and auxiliary winding wire diameters and the number of turns are different, and the DC resistance value is also different. Use a multimeter resistance file. Assuming that any terminal is the C terminal, contact one test lead of the multimeter with the assumed common terminal and the other test lead respectively with the other two terminals. If the measured resistance values are 3.5 and 4.2, respectively. If the assumption is correct, then the other end with the smaller resistance value is the main winding end R, and the other end with the slightly larger resistance value is the secondary winding end S. Using the same method to assume up to three times, you can find the common terminal C and the main winding end R and secondary winding end S. 3. The compressor has a total of three connection points, so let's first understand and two of the three are to start and run these two windings respectively. Hitachi ultra-low temperature heat pump compressor can use a multimeter to put the above windings To distinguish, find the common point, the resistance of the starting winding is less than the running winding. After distinguishing the three points, the next step is wiring. The compressor, remember that the common point is generally marked with the letter C, use the zero line to connect to the common point C, and use the live wire to connect to one of the capacitor points. The other point of the capacitor is connected to a point of the start winding of the air-conditioning compressor, and the point of the compressor's running winding is connected to the fire line of the capacitor at the beginning. The above part about how to measure the quality of the air conditioner compressor and the tips of the air conditioner compressor wiring are introduced here, I hope these are helpful to everyone.
Compressor composition structure The air-conditioning compressor is the core component in the air-conditioning system, and is usually called the main unit of the refrigerator. So what are the components of the compressor? compressor 1) Terminal; 2) Upper cover; 3) Housing; 4) Stator; 5) Rotor; 6) Crankshaft; 7) Screw; 8) Upper bearing; 9) Cylinder; 10) Piston; 11) Lower bearing; 12) Lower cover; 13) Machine foot; 14) Link pipe; 15) Silencer cover; 16) Liquid reservoir; 17) Exhaust pipe; 18) Suction pipe . The above are all the components of the compressor. With the continuous progress of science and technology, the continuous emergence of new air-conditioning systems has directly promoted the continuous progress of air-conditioning compressor manufacturing technology.
