Cooling tower hka hta TDS grai law ai byin pru wa ai lam gaw hka a matut manoi n-gun jat ai lam hta nga ai.

 

Cooling tower ni gaw hka n-gun hpe shapraw kau na matu hka n-gun hpe kam hpa nna, san seng ai hka gaw nbung de n-gun n-gun rawng mat nna, hka lim mat ai mineral substances yawng gaw n-gun n rawng mat nna, shinggrup nga ai hka hta matut manoi nga nga ai.

Hka hkin gau na jakrung ni hta, hka htung kata na chloride ions ni gaw TDS hpe grai jat shangun ai; lung seng htu ai hte tsi htu ai shara ni hta, sulfates hte n-gun ja ai nhprang dat ni hta rawng ai n-gun ni gaw TDS hpe madang hta grau lawan ai hku lai shangun ai.

 

Closed cooling system ni hta TDS rawt jat wa ai lawan ai lam yawm ai, hpa majaw nga yang, kata na n-gun gaw nbung kaw na tsan gang nga ai, rai tim aten galu-bungli galaw ai hte hka hpe ayan bai jat bang ai gaw TDS n-gun yawm ai hpe naw byin shangun na re.

 

 

TDS grai law ai gaw, cooling tower hte madi shadaw ai arung arai ni a matu si hkrung si htan kaba masum hpe shabyin ya ai. Shawng nnan na hkrit tsang hpa gaw grai sawng ai scaling re. TDS a matu Calcium hte Magnesium sau ni gaw madung rai nga ai. When TDS exceeds the set threshold, the solubility limit of calcium carbonate, magnesium silicate and other precipitates is broken, and crystalline scale adheres to the surface of heat exchangers, coil pipes and condenser tubes.

 

 

Scale gaw grai n-gun n law ai thermal conductivity nga ai majaw, nbung galai shai ai lam hpe grai shayawm ya lu ai. Scale thickness 0.3mm du wa ai shaloi, katsi ai jak ni a katsi ai hpe shapraw kau lu ai atsam 20% jan hkrat sum mat ai majaw, jak ni grai katsi mat ai, galaw shapraw ai lam hpe pat kau ai hte fan hte hka pump ni a power jai lang ai lam grau law wa ai.
