In general, the injection molding machine hydraulic system failure is not accidental, any failure in the evolution of a major failure will be accompanied by a variety of abnormal omens, these omens can be summarized as:
1, abnormal sound, such as pumps, motors, temperature flow valve and other parts of the sound is not normal.
2, the phenomenon of slewing, traveling, winch hydraulic motor and the hydraulic cylinder of each working device operating speed drop and powerlessness.
3, there is a drop in oil tank level, oil deterioration phenomenon.
4, hydraulic components on the surface of the oil leakage phenomenon.
5, the phenomenon of high oil temperature.
6, pipeline damage, loosening and vibration phenomenon.
7, the emergence of coke nucleus odor and so on.
These phenomena, as long as the use of the process of careful attention, can be observed with the naked eye, hand touch, nose smell found. In practice, it is through this on-site means to analyze the failure of the first-hand information, and then according to experience, the synthesis of these first-hand information, specific analysis of the actual problem, to find out the reasons for the failure, and to be resolved as early as possible. However, in practice, often can not be accurately diagnosed once the cause of the failure, it is necessary to several repeatedly, that is, repeatedly analyze, repeatedly check until you find the cause of the failure.
