Closed Circuit Cooling Tower ni hpe bungli galaw na matu ahkyak ai lam ni

 

Closed circuit cooling tower ni a ngang grin ai bungli galaw ai lam hte magam bungli prat gaw, madang masat da ai start-up hte shutdown, hkrak tup yu reng ai lam, hka a hkamja lam hpe hkang zing ai lam, aten ladaw hpe makawp maga ai lam, aten tup gram lajang ai lam ni hta madung nga ai. Madung bungli galaw ai lam ni hpe lawu de tsun dan da ai.

 

 

 

 

 

 

 

 

1. Startup n galaw shi yang, tsep kawp jep joi ai lam

 

 

Hkrang hte Pipeline hpe jep joi ai lam: Tower shell hte support hpe n kaja ai (sh) hkra machyi ai kun ngu ai hpe jep yu u. Fan hte motor makawp maga ai arung arai ni hpe n hkrat sum hkra galaw u. Inlet/outlet pipeline ni hpe atsawm sha matut da ai, valve ni kaja hkra bungli galaw ai, filter ni san seng ai hte pat shingdang ai lam n nga ai, pipeline madi shadaw ai lam ni gaw bungli galaw ai shaloi byin pru wa ai hka lim ai lam hpe koi gam na matu ngang grin ai hpe jep yu u.

 

System Venting hte Hka hpe bai jat bang ai: Nbung hpe n-gun shayawm ya ai nbung n-gun hpe koi lu na matu, nbung hpe shinggrup ai hka htung hte hka htung kaw na nbung hpe tsep kawp shapraw kau na matu nbung pru ai valve ni hpe hpaw u. Sump kata na hka n-gun hpe jep yu nna, pump htum mat ai (sh) hka n-gun n-htum mat hkra, float valve (sh) automatic makeup hku nna, hka n-gun hpe madang de gram lajang u.

 

Wan hte Hkamja Lam hpe jep yu ai: Motor wiring ni ngang kang ai, grounding kam mai ai, insulation ninghkap ai lam ni gaw madang ni hte maren rai nga ai hpe jep yu u. Control panel display ntsa na jak ni hte masat kumla nhtoi ni hpe hkrak hkra galaw nna, switch ni hpe atsawm sha galaw lu hkra galaw u. Fan (sh) spray system kata de maigan arai ni n shang hkra, tower grup yin na nhprang arai ni hpe yeng seng kau u.

 

Medium htuk manu ai lam hpe madi shadaw ai lam: Katsi ai ntsin gaw coil arung arai ni hte htuk manu ai hpe sadi ra ai (ga shadawn, ammonia media a matu magri mang hka htung ni hpe pat hkum da ai) coil hpe chemical n-gun n-gun n-rawng ai, hka pru wa ai, n-gun n-rawng ai hpe koi gam na matu.

 

 

2. Running galaw ai aten hta hkrak tup yu reng ai lam hte bungli galaw ai lam

 

 

 

N-gun ja ai Start/Shutdown ladat: Hka shinggrup ai pump hpe shawng hpaw hpang u. System hpring nna nbung pru wa ai hpang, fan hpe hpaw dat u. Shutdown galaw na matu, fan hpe shawng jahkring kau nna, minit 10-15 lapran na ai hpang pump hpe jahkring kau ra ai, coil hpe atsawm sha katsi shangun nna, thermal shock hkra machyi ai lam hpe koi lu na matu.

 

Madung masat masa ni hpe yu reng ai lam: Hka shang/pru hka n bung ai hpe 5–15℃hta tawn da ra ai . Kaji ai shai hkat ai lam gaw, n san seng ai (sh) n-gun yawm mat ai hpe madun chye ai; shai hkat ai lam kaba gaw grai law hkra lit la ai hpe tsun mayu ai. Hka n-gun hpe yu reng u: akajawng sha hkrat wa ai gaw hka pru ai hpe madun ai, akajawng sha rawt wa ai gaw filter hpe pat kau ai hpe tsun mayu ai. Nozzle n-htum hkra, coil hpe tup hkrak shinggrup lu hkra, spray uniformity hpe yu u.

 

Hka a san seng lam hpe hkang zing ai lam: pH (6.5–8.5), n-gun ja ai, n-gun n-gun, hte n-gun n-gun n-rawng ai n-gun hpe ayan jep yu ra ai. Scaling, n-gun n rawng ai, algae ni n byin hkra, n-gun n rawng ai, n-gun n rawng ai, bactericides ni hpe bang u. Sump kata na floating matter hpe bat mi hta kalang jasan jaseng nna, nozzle n pat hkra shata mi hta kalang filter ni hpe hka garan ya ra ai.

 

Fan hte Drive hpe jep yu ai: N kaja ai nsen (sh) n-gun rawng ai hpe madat u. Shata shagu belt a n-gun hpe jep yu u. Motor hte bearing a n-gun hpe ( 75℃hta n-pu (sh) maren sha ) yu nna, shata kru shagu hta n-gun ja ai-n-gun ja ai sau hpe bang nna, n-gun n-gun rap ra ai lam hpe hkrak hkra galaw u.

 

 

 

3. Aten ladaw hte maren makawp maga ai lam

 

 

 

Katsi majan hpe makawp maga na matu (ahkyak ai): Matut manoi galaw ai gaw kaja dik htum antifreeze masa re. - aten galu pat da na matu, coil, spray system, pipeline ni kaw na hka hpe tsep kawp shapraw kau nna, ngam ai hka hpe nbung n-gun hte jasan jaseng kau ra ai. Shinggan na pipeline ni a matu wan n-gun n-gun hpe hkan tam ai hte insulation hpe jung u. Ra ai rai yang, ethylene glycol hpe n-gun n jaw ai tsi hpe lang u.

 

Summer Hkringhtawng-Katsi ai Magam Bungli: Jep joi ai lam hpe law law galaw nna, mawdaw a nbung katsi ai lam hpe myit maju jung na. Nbung shang wa ai louvers hte coil ntsa ni hpe san seng hkra galaw nna nbung shang wa ai hte katsi ai hpe galai shai shangun ai. Peak high temperature aten hta spray flow hpe jat nna, grai katsi ai shutdown hpe koi lu na matu galaw u.

 

 

 

4. Galoi mung gram lajang ai lam hte pat kau ai lam hpe yu lajang ai lam

 

 

 

Hkamja lam aten ladaw: Hka madang, n kaja ai nsen ni hpe bat shagu jep yu u. Filter ni hpe jasan jaseng nna, nozzle ni hpe hpaw nna, wan n-gun hpe shata shagu ngang ngang jum da u. Coil ni hpe n-gun n law ai hka hte shata mali hta kalang kashin kau nna, fan blade balance hte gearbox sau n-gun hpe jep yu u. Shaning shagu chemical hte jasan jaseng ai lam galaw nna, coil n-gun n rawng ai hte hka pru ai hpe jep yu nna, moi na seal ni hte bearing ni hpe galai kau ra ai.

 

Galu-Aten galu pat kau ai ladat: Hka yawng hpe hka ja kau nna, kata na nhprang arai ni hpe jasan jaseng kau ra ai. Fan hte nbung shang ai shara ni hta ga nhpu n shang hkra makawp maga ai shingnip ni hpe bang da u. Power hpe dawm kau nna, unit hpe atsawm makawp maga u. Bai n lang shi yang, pre-startup hpe tup hkrak jep yu u.

 

 

 

 

5. Hkamja lam hte N-gun atsam-Hkye la ai lam

 

 

Unit grup yin hta shimlam masat kumla ni hpe mara nna, gram lajang ai aten hta lockout–tagout ladat ni hpe hkan sa ra ai. Fan hte pump a n-gun hpe thermal load hte maren shatai na matu galai shai ai frequency drive ni hpe lang u. -katsi ai aten ni hta, n-gun jai lang ai lam hpe shayawm na matu, hka htung hpe dry-operation mode a matu pat kau mai ai.
