Hydraulic steering easier in use problems are mainly the heavy steering, steering deviation, steering and steering made from time to time before the noise, such as abnormal sound.
An abnormal sound heard in auscultation.
Therefore, it is necessary to establish an evaluation system of engine abnormal sound that detects engine sound objectively and quantitatively and improves the accuracy.
For a group of grinding wheel machines, we have explored the corresponding relationship between abnormal sound and machine fault, and also pointed out the resolving method of the machine fault.
Spindle connected servo motor belt tension can not be too tight, too tight can easily lead to wear of the belt, the phenomenon of skidding, abnormal sound.
The results show, three kinds of method can identify abnormal sound of cylinder head.
Main fault models are leaking oil, no absorber function and abnormal sound, and abnormal sound is 50 to 60 percents in the reflection of consumers.
The machinist pressed his ear to the instrument in order to listen and tell where the abnormal sound came from.
This product has been very good to do environmental testing, the successful solution of the low-temperature humidity light color, abnormal sound, the phenomenon of leakage of powder.
The working conditions, the causes of failures, the early diagnosis for abnormal sound and the maintenance methods are described in this paper.
