In order to use the compressor well, in addition to understanding the correct operation method of the compressor, you also need to understand some causes and solutions of compressor failure. People who have used the compressor may encounter the phenomenon of compressor burning. So, now we come to understand some, what exactly causes the compressor to burn the tiles?
1. The amount of oil in the oil pan (or crankcase) is insufficient, or the oil passage is not smooth, which results in poor lubrication. The quality of the bearing alloy is not the same, and the alloy and the bottom tile can not be completely close together. Second, the oil pressure is too low, the normal normal oil pressure should be 0.15~0.3MPa, when the oil pressure is lower than .08MPa, you should immediately stop and check. 3. The ellipticity of the crankshaft journal exceeds the requirements, so that the engine oil cannot form a certain oil film during the lubrication process, resulting in poor lubrication. The large end of the connecting rod is worn, which causes the back of the bearing pad and the large end of the connecting rod to not closely fit together, causing the connecting rod to burn the tile. 4. The matching contact surface of the bush and the journal does not meet the requirements, usually the contact area is not less than 75%, and the contact points are evenly distributed. If the assembly gap between the bush and the journal is too large or too small, the oil cannot be lubricated during lubrication. A certain oil film is formed, resulting in poor lubrication. Fifth, the center of each main bearing shell is inconsistent, which causes the crankshaft to run in the main bearing pad, and some places are large and thin, forming dry friction, which may cause burning of the tile in severe cases. Only after we truly understand the cause of compressor burn-out failure can we take correct measures to deal with this failure.
