Precautions for Repairing Plastic Machinery

Precautions for repairing Plastic machinery

(1) When finding the fault point and repairing the fault, it should be noted that the found fault point cannot be regarded as the end point of finding the fault. It is necessary to further analyze and find out the root cause of the failure. For example, when dealing with an accident that a motor burn due to overload, it must not be considered that repairing the burned motor or replacing it with a new motor of the same model is the end, and it is necessary to further investigate the cause Of the motor overload, whether it is due to the load. too heavy. It is caused by the improper selection of the motor and too small power because both will cause the motor to overload. Therefore, when dealing with faults, repairing the fault should be carried out after finding the cause of the fault and eliminating it.

(2) After finding the fault point, be sure to take the correct repair methods for different fault conditions and locations. Do not easily use methods such as replacing electrical components and patching wires, and it is not allowed to easily change lines or replace electrical components with different specifications. To prevent human malfunction.

(3) In the repair of the fault point, under normal circumstances, it should be restored as much as possible, but sometimes it is necessary to restore the normal operation of industrial machinery as soon as possible. According to the actual situation, it is also allowed to take some emergency measures suitable for the mold flushing machine. But never improvise.

(4) When the electrical fault is repaired, it needs to be powered on for trial operation. Cooperate with the operator to avoid new faults.

(5) After troubleshooting each time. Experience should be summarized in time, and maintenance records should be made. The recorded content includes the model, name, number, date of failure, failure phenomenon, location, damaged electrical appliances, failure reason, repair borrowings, and operation after repair. Situation and so on. The purpose of recording is to serve as a file for future maintenance reference, and through the analysis of previous failures, corresponding effective measures are taken to prevent the recurrence of similar accidents or to propose improvements to the design of the electrical equipment itself.
