When the Used Portable Concrete Crusher is started, the motor does not rotate. If an external force is applied, the motor will rotate but will emit a weak electrical sound. At this time, it can be considered as a leakage of the capacitor. If the current sound is too loud, the motor will not start or the capacitor will be shorted. At this time, let the professional maintenance personnel repair it. When repairing, if there is no professional maintenance instrument, you can remove the capacitor, insert the two wires into the neutral socket, and connect the cables for charging.
Then take out the wire and discharge. If an electric spark can be generated, the capacitor can continue to be used. If the spark is weak, the capacity of the hammer crusher will be reduced and new capacitors or small capacitors will need to be replaced. However, if the capacitor is damaged, it must be replaced and cannot be processed as described above. Hammer crusher rack-to-port maintenance method: For long-term work of the detachable frame, the flat surface at the other end of the rack will wear. In this case, it should be resolved in time. The specific method is as follows: First, the wear of the hammer crusher frame is measured, the specific value of the grinding deviation is determined, and then the electric welding planer is performed.
But be sure to ensure the center-to-center spacing of the original bearings. Rack crack treatment: The hammer crusher frame is an important load-bearing component, so cracks may occur in the weak part of the frame. If the frame breaks, it can be repaired by welding. The vibration of the hammer crusher is exacerbated during operation, indicating that there may be uneven wear between the wear component and the rotor, which is caused by an imbalance or looseness caused by the asymmetric rotor and material. Pulley cover. After removing the normal vibration, the inspection can be stopped.
In addition, the vibration switch mounted on the hammer crusher can be set to actively stop before equipment damage and personal injury occur when unbalanced vibration is detected. When the crushing sander is fed, an unbalanced process of about 30 to 60 seconds usually occurs. In this case, the feed cannot be stopped, and the feed amount is increased as much as possible until the vibration is lowered.
