Daily maintenance content of induction melting machine
1. Check whether there is any leakage or leakage in the circulating cooling water circuit of the furnace body, and display the pressure gauge reading
2. Remove iron filings, iron lump and slag around the furnace body and water-cooled cables.
3. Check if there are any abnormalities in the furnace oil tank and the water-cooled cable.
4. Check the corrosion of the furnace lining.
Routine maintenance of induction melting machine 2 (intermediate frequency power supply cabinet):
1. Check if there is any leakage in the circulating cooling water system of the power cabinet.
2. Check whether there is water leakage and water collection in the power cabinet.
3. Check whether the display of all working lights and fault indicators is normal.
4. Check whether the capacitor in the power supply cabinet is leaking oil or bulging.
5. Check whether there is heat or fire at the copper bar connection in the cabinet.
Daily maintenance of induction melting machine 3 (cooling tower and emergency system):
1. Check the water storage in the cooling tower reservoir.
2. Check whether the spray pump and fan are operating normally.
3. Check whether the emergency pump works normally and whether the pressure is normal.
Monthly maintenance content of induction melting machine 1 (furnace body):
1. Check whether the coil is sparking or discolored. Whether the supporting wood is broken or carbonized.
2. Check the tightness of the magnetic yoke, check the rotation of the furnace cover of the lifting cylinder, and whether there is oil leakage in the cylinder, and adjust its speed.
3. Check whether the front shaft pin of the furnace frame and the shaft pin of the lifting cylinder are worn and loose, and add lubricating oil to the rotating part.
4. Check the water-cooled cables and water pipes.
Monthly maintenance content of induction melting machine 2 (power cabinet):
1. Check the electrical conductivity of the cooling water of the power supply, the requirement is less than 10us.
2. Clean the dust on the module and main control board at all parts, and fasten the wiring terminals on the module.
3. Check the condition of the discharge resistor.
Monthly maintenance of induction melting machine 3 (cooling tower and emergency system):
1. Check the fan, check the bearing seat and add oil.
2. Check the temperature setting of the spray pump and fan, and check whether the linkage is normal.
3. Clean the pool and remove debris from the water inlet filter of the spray pump.
4. Check and operate whether the emergency system is working properly.
