Any equipment will be worn out in the process of use. As long as it is properly maintained, the service life of the equipment can be effectively extended. What should be known in advance during NC welding?
Check whether the power supply of the equipment is normal
Whether the power supply is normal is related to whether the equipment can be used normally and the service life of internal components. For example, if the power supply is short of power, it is often easy to guide the internal filter capacitor of the equipment to burst, the IGBT is seriously heated and even burst, and other abnormal conditions. Inspection items:
Whether the power inlet connector at the power supply switch is connected reliably, and whether there are abnormal conditions such as oxidation, discoloration, smoking, redness, etc; Measure whether the grid voltage is within 380V ± 15%; Whether the appearance of the power supply line is damaged, extruded and deformed; If the power line is lengthened, it is necessary to check whether the intermediate connection joint is firm and whether the insulation treatment is reliable.
Check whether the output connection of the device is normal
Whether the output connection is reliable is related to the stability of welding (cutting) process, connection life, etc. For example, if the quick connector at the output end is loose, it is easy to ignite and burn the connector during high current welding (cutting), resulting in the scrapping of the whole connector, and it is troublesome to replace it. Inspection items:
Whether the welding (cutting) cable connection at the output end is reliable, and whether there are abnormal conditions such as blackening, smoking, charring, etc; Whether the joints of the welding gun (cutting gun) at the output end are connected reliably, and whether there are abnormal conditions such as air leakage and water leakage; Whether the connection of the control line connector at the output end is reliable, and whether the appearance of the control cable is damaged, extruded and deformed. Inspection frequency: the connection mode is quick connector connection, which should be inspected once a day before operation; The connection method is bolt and nut connection, which should be checked once a week.
4. Check and tighten the connecting screws of the conductive parts inside the equipment
Shandong CNC welding equipment manufacturers suggest that the parts fastened with bolts and nuts will slowly loosen due to heating, vibration and other reasons. If it is not fastened in time, the whole connection point will be burned and the whole machine will not work. After dust removal, the connecting screws of the main conductive parts inside the equipment shall be checked and tightened. If the contact has sparking phenomenon, the connection point should be polished, coated with conductive silicone grease, and then reconnected.
In addition, during the long-term use of the welding machine, it is inevitable that the shell will be deformed or rusted due to the collision of external forces, and the internal parts will also be worn away. Therefore, the parts should be replaced or the shell repaired in time during the annual maintenance and inspection. Come to the website for more relevant content http://www.lexjustis.com Consult.
