Nonwoven slitter is an important Slitter which is often used before and after printing. It is widely used. However, any equipment is difficult to avoid the occurrence of some electrical faults, so the maintenance of the equipment has become the homework that users need to master. How to repair the electrical fault of non-woven Slitter? Now follow Zhengxin packaging factory to learn about it!

Maintenance steps after electrical failure of non-woven Slitter:

1、 Preparation: prepare the tools, instruments, machine circuit diagram and other data for the maintenance of the non-woven slitter.

2、 Reading diagram: for the non-woven slitter to be overhauled, first of all, it must be able to read the circuit schematic diagram of the equipment.

3、 Through the five steps of asking, looking, touching, listening and operating, we can find out the fault phenomenon and the situation before and after the fault.

1. Ask the operator of the non-woven Slitter about the situation before and after the failure to understand whether the failure occurred suddenly or often? What are the anomalies? What's wrong? Wait. In this way, mastering the initial first-hand information accurately is conducive to judging the fault location and quickly finding the fault point.

2. Carefully observe the surface condition of machine tool electrical appliances or circuits. Then start the machine, listen to the motor, control transformer, contactor, relay, etc. for abnormal sound and closing sound. After a period of operation of the machine tool, cut off the power supply, use the hand mold to check whether there is more than normal heating phenomenon.

3. All the functions of the non-woven Slitter are demonstrated one by one. In the step-by-step operation, carefully observe the operation process, and find out the electrical fault of the machine tool, so as to quickly and accurately determine the electrical fault range of the machine tool.

4、 According to the fault phenomenon of the non-woven slitter and the circuit diagram, the approximate range of the fault is analyzed. After the above process of "ask, see, listen, touch and operate" is basically clear about the fault phenomenon, then the approximate range of the fault can be analyzed by combining the circuit diagram, and then the corresponding detection method is used to find out the fault point.

The maintenance steps of the non-woven Slitter are basically the five steps mentioned above. Of course, this is only a reference for the maintenance steps after the electrical failure of the non-woven slitter. It is recommended that the specific troubleshooting work be operated by professional personnel.
