In the operation of plate bending rolls in anomaly analysis

Machine in the abnormal phenomena in the operation of analysis: ( 1) Abnormal temperature rise. Common in various machine used by the motor and gear box bearing. Temperature exceeds allowable values, lapping machine overload or component failure, serious when can smell the stench of lubricating oil and saw white smoke. ( 2) Speed anomalies. Machine speed suddenly over or below the normal speed, may be due to the sudden changes in load or trigger a mechanical failure. ( 3) Vibration and noise is too big. Machine due to vibration and the failure rate of the total 60% ~ 70%. Its reason is various, such as machine design, machine manufacturing flaws, installation, parts action imbalance, lack of parts wear, lubrication, into foreign body in plate bending rolls, etc. ( 4) A crash. Loose parts fall off, enter the foreign body, rotor imbalance are likely to produce sound. ( 5) Abnormal input/output parameters. Changes are: machining accuracy; The consumption of machine power exception; When machine to run in spite of the output change, etc. ( 6) Machine internal defects. Including crack of machine parts, electrical equipment insulation quality decline, due to corrosion defects, etc. This article reprinted from laser cutting machine
