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.
