Bucket tooth pin manufacturer science shovel abnormal noise factor

　　Bucket tooth pin manufacturer tells the user that the abnormal noise of the bucket is related to the temperature. When the temperature is too low, the low temperature will sound, and the sound will be reduced or even disappear after the temperature rises. The reasons for the sounding are: the gap between the piston and the cylinder wall is too large; the piston is out of alignment due to the depth and width of the main bearing oil groove; the oil pressure is low and the lubrication is poor.

　　Bucket tooth pin manufacturer tells the user that there is a sound when the temperature rises, and the sound is reduced or disappeared after the temperature is lowered. The reasons for the sound are: pre-ignition caused by overheating; the long and short axes of the ellipse of the piston skirt are opposite; the ellipticity of the piston is small, and the gap between the piston and the cylinder wall is too small. The piston is deformed and the gap between the piston rings is too small.

　　Bucket tooth pin factory tells the user that the abnormal sound has a relationship with the engine working cycle. The abnormal noise of the engine is often related to the working cycle of the engine. In particular, the abnormal noise of the crank connecting rod mechanism and the valve distributing mechanism are related to the working cycle. In the case of a four-stroke engine, the sound caused by the crank-link mechanism is the engine's work twice. The sound caused by the valve train is once the engine work once. The abnormal noise caused by the crank-link mechanism is caused by the piston striking the cylinder wall and the knocking sound of the piston pin. The piston top cylinder head, the connecting rod bearing is too loose, and the piston ring leaks.
