As an important part of metal laser cutting machine, the maintenance of metal laser cutting machine power supply is self-evident. In the process of use, we should often inspect the working state of the regulator of the metal laser cutting machine to prevent the occurrence of faults, so as to greatly improve the service life of the metal laser cutting machine.
The inspection of the regulated power supply of the metal laser cutting machine is mainly to observe the compensation transformer to see whether the temperature rise of the voltage regulating transformer is normal, whether there is overheating, coil discoloration and other phenomena. Whether the contact of the carbon brush is maintained well, and whether the input and output voltage are normal, whether there is overload, etc.
In order to carry out more strict maintenance, remove the dust and dirt from all parts of the pressurizer of the metal laser cutting machine every three months, check whether the chain drive system works normally, add oil to the sprocket, adjust the tightness of the chain, check whether the carbon brush holder is inclined or stuck, and adjust it if found.
In addition, check whether the electrical contacts of the metal laser cutting machine are damaged. If so, replace or repair them in time: check whether the column voltage regulating transformer operates flexibly, whether the carbon brushes are intact, and replace the damaged or severely worn carbon brushes in time.
