Induction heating equipment - maintenance and maintenance




Induction heating equipment - maintenance and maintenance Weekly maintenance Check the flow rate of the equipment cooling water outlet pipe during the shift. Equipment using evaporative cooling tubes, check the water level of the distilled water tank is qualified; Check the cooling air volume of the glass tube and the stem of the tube and other ventilation and cooling facilities during the succession; Check the contacts of each AC contactor for ablation, and whether the wiring is loose or not; Measure the insulation resistance of the cooling water. The earth resistance of the anode of the water-cooled tube should be greater than 300K ohms; The cooling pipe of the tube and the filament of the tube are mostly rubber tubes, which are easy to age and should be inspected carefully. For rubber tubes that have been aging and will be ruptured, they should be updated in time;


Half year maintenance Check whether the insulation performance of the low-voltage electronic control circuit is qualified; Use a megohmmeter to detect the insulation resistance of high-voltage devices such as high-voltage rectifier transformers, high-voltage cables, high-voltage silicon reactors, etc., and their values ​​should meet the requirements; Check the roundness of the inner tube of the water tube of the tube and the height of the positioning protrusion to prevent the tube from being overheated due to the deflection of the tube. And check whether there is no scaling at the outlet of the water jacket and the joint of the inlet pipe, and whether the anti-corrosion electrode is normal; Check the setting current value of each overcurrent relay; For connecting conductors with higher temperature during operation, such as filament lead wires, soft connecting wires of primary coils of welding transformers, etc., if there is a bad contact with oxidation, it should be processed separately; Overhaul of motors, pumps, and motors

Thorough cleaning of concealed areas such as the top of the cabinet, cable trenches, etc.
 
Clean and dust the inside of the chassis, wipe off the dust of each high-pressure porcelain bottle and insulation pillar, and pay attention to the cleaning of the dust filter on the air inlet of the fan. Prevent the intake air from being blocked and the air volume to decrease.Induction heating equipment - maintenance and maintenance Weekly maintenance Check the flow rate of the equipment cooling water outlet pipe during the shift.
