Motor Vibration

If the bolt and vibrates, the in this way to check whether the difference in vibration at the interface between the foot and the frame, between the upper shelf and the vertical part of the frame, between the stiffening rib and the upper and lower shelves, bottom shelf between frames and foundations and etc. Sometimes a violation of a durable interface between the parts is also revealed by the appearance of fine bubbles, and with a strong vibration – and the fine spray of oil in place of the joint. If you find a defect in the interface between the frame and foundation that appears most often due to corrosion of concrete with oil, all impregnated concrete, including strength and yet retained must be removed and replaced with fresh. On the setting time of concrete aggregate should be stopped and removed from the reserve. If defects in the foundation, frame, motor mount and socket covers, mounting driven machine is not found, should Release the clutch between the motor and mechanism and run the motor idling. If, at the start and at idle speed motor operates without vibration, the cause of the vibration to be found in violation of the alignment, wear pins or hubs themselves or the appearance of imbalance in the reducible mechanism. If the motor vibrates at idle, the cause of the vibration is located in the motor. In this case, you should check does not disappear if vibration immediately after disconnecting the motor from the network. The disappearance of the vibration immediately after being disconnected from the network indicates the presence of non-uniform gap between the rotor and the stator.
