Use of Rotor Wear Parts of Hammer Crusher

Oct.11, 2021
When the hammer crusher is started, the motor will not rotate. If an external force is applied, the motor will rotate but produce a weak electric sound. At this point, you can think of a leakage of the capacitor. If the current sound is too loud, the motor will not start or the capacitor will short-circuit. At this time, let the professional maintenance personnel to repair it. During maintenance, if no professional maintenance equipment is available, remove the capacitor, plug the two wires into a neutral socket and connect the cables for charging.
Then take out the wire and discharge it. If an electric spark can be produced, 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 treated as described above.
Hammer crusher rack to port maintenance method: for the long term work of the detachable rack, the plane 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, measure the wear condition of hammer crusher frame, determine the specific value of grinding deviation, and then conduct electric welding planer.
But make sure the center spacing of the original bearing is ensured. Frame crack treatment: the hammer crusher frame is an important bearing part, so cracks may appear in the weak part of the frame. If the frame breaks, it can be repaired by welding.
The vibration of hammer crusher is intensified during operation, which indicates that there may be uneven wear between the worn parts and the rotor, which is caused by unbalanced state or looseness caused by asymmetric rotor and materials. The pulley. After removing the normal vibration, the inspection can be stopped.
In addition, the vibration switch installed on the hammer crusher can be set to stop actively before equipment damage and personal injury occurs when unbalanced vibration is detected. When the crushing and sanding machine is fed, the unbalanced process of about 30~60s usually occurs. In this case, the feed cannot be stopped and increased as much as possible until the vibration is reduced.
When the feed particle is large, intermittent vibration will occur and return to normal state after a few seconds. This is due to the fact that a certain throwing head of the rotor stagnates and eliminates the normal situation caused by the accumulation of accumulated materials. Tension. The rotor wear parts of hammer crusher are designed to protect the rotor body from wear.
In order to ensure the trouble-free operation of the hammer crusher, it is necessary to check the wear-resistant parts of the rotor and the lining of the machine in daily work, and it is not allowed to replace the wear-resistant parts of the working class in a timely manner. Check the inside and outside of the rotor and hammer crusher every 8-10 hours of operation and add grease to the bearing box.
