Influence the quality of cooling water on high frequency furnace and medium frequency induction furnace

Previously introduced in high frequency electric welding, high frequency heating machine, high frequency machine and other equipment to use, to pay special attention to quality problems in cooling water system, if the water quality is not good, willcause conduit jam, power supply circuit, open circuit etc.. So Ibring you harm to water quality problems.

Cooling water to achieve the following requirements:

High frequency furnace cooling equipment

First, is the water purity: quality high frequency electric furnace, high frequency welding machine and other equipment requirements see visually if clean, colorless, transparent, nonturbid, no sediment.

Second, in the field of Chemistry: high frequency electric furnace, high frequency furnace and its water quality to aneutral or weak alkaline, pH value 7~8.

Third, the hardness is the high-frequency heating machine, the high frequency furnace water quality: high frequency electric furnace, high frequency furnace requires its hardness is 8 ° DHcarbonate hardness.

Fourth, a high frequency electric furnace, heating furnace ofthe conductivity: the conductivity value should be max600 μ S/cm, min50 μ S/c

Quenching machine cooling water temperature is fifth, high frequency electric furnace, ultra audio frequency: thetemperature control in max+35 ℃, min+5 ℃, as the most suitable temperature.

Sixth, the high frequency electric furnace, high frequencyinduction heating power scaling problem in temperature: 8 ° DH,the water temperature is 50 ℃ begins to produce change and limestone, phosphate precipitation. Need to add antifreeze, must not add commercial antifreeze (such as automotive antifreeze),it will be ionized and discharge in a certain voltage.

Seventh, is the high frequency electric furnace, high frequency furnace cooling problems: high frequency electric furnace, high frequency furnace with open and closed cooling tower. Open (pooland cooling tower, plate heat exchanger). Suggestions for closed type cooling tower.

Closed cooling tower will be cooling water and air through the medium of coil and the heat exchange tube, forming a closedcycle system, effectively avoiding the cooling tube fouling,clogging, damage to electronic components (such as IBGT module,inductor, capacitor). Especially in large power equipment, heat,using closed-loop cooling tower, can guarantee the stability andservice life of equipment.
