Shanhte a n-gun n law ai hkrang hte n-gun hpe atsawm sha htawt sit lu ai majaw, spiral heat exchanger ni hpe chemical, energy, hte kaga lam ni hta grai lang ma ai. Aten galu-, ngang grin ai hku bungli galaw lu na matu ayan jep joi ai lam gaw ahkyak nga ai. Lahta na gaw core jep joi ai lam rai nga ai:
1. Hkrang nsam hte npawt nhpang hpe jep joi ai lam .
Shawng nnan, jak a shinggan maga de n-gun n rawng ai, n-gun n rawng ai, hka pru ai kumla ni nga ai kun ngu ai hpe jep yu nna, weld, pipe matut mahkai ai lam, flange matut mahkai ai lam ni hpe madung tawn nna jep yu u. Bai nna, npawt nhpang hpe ngang ngang jum da ai hpe mung, bungli galaw ai shaloi, n-gun n rawng ai majaw, n-gun grau ja wa hkra, n-gang n-gang ni hpe n-gun n rawng ai hpe mung jep yu u.
2. N-gun hpe chyam yu ai
Hka (sh) nbung n-gun hpe chyam yu ai hku nna n-gun ja ai hpe jep yu ai. Hka n-gun hpe design n-gun htam 1.25 lang chyam yu ai hpe lang ai, minit 30 na ai hpang n-gun n hkrat ai. Nbung n shang hkra chyam yu ai shaloi, nitrogen zawn re ai n-gun n rawng ai nbung hpe lang nna, hka lim ai hpe mu lu ai jak (sh) sensor hpe lang nna, hka lim ai hpe kaji kajaw mu lu ai.
3. Katsi ai htawt sit ai lam hpe jep joi ai lam
Inlet hte outlet media a nbung n-gun, n-gun, lwi ai n-gun hpe shadawn nna, tengman ai nbung n-gun htawt sit ai coefficient hpe sawn la nna, design value hte shingdaw yu u. N tara ai hku nbung laru shai hkat ai (sh) hka lim ai lam akajawng sha hkrat sum ai gaw, scaling, blockage, shing nrai, kata na daw ni hpe hkra machyi ai majaw, n-gun yawm mat ai hpe madun ai rai na re.
4. Kata na hkrang hpe jep joi ai lam
Baw hpe shaw kau ngut ai hpang, spiral plates ni hta nsam galai shai ai, n-gun n rawng ai, shing nrai, n-gun n rawng ai hpe myi man hte yu yu u. Ultrasonic thickness gauge lang nna, hka lwi ai shara ni hta n-gun n rawng ai hpe grau nna sadi maja let, plate kade daram n-gun rawng ai hpe shadawn yu u. Bai nna, spacers hte seal ni a dinghpring ai lam hpe jep yu nna, ra ai hku hkrat sum mat ai arung arai ni hpe galai kau ra ai.
5. Bungli galaw ai lam hpe yu reng ai
Dai jak hpe bungli galaw nga ai aten hta, n bung ai (sh) shingjawng ai lam ni nga ai kun ngu ai hpe chye lu na matu, n kaja ai shingjawng ai lam ni hpe sawk sagawn na matu, shingjawng ai lam hpe jep chyoi ai jak (vibration analyzer) hpe lang u. Infrared thermal imaging gaw, buga ginra hta grai katsi ai shara ni hpe tam mu lu nna, byin mai ai hkrat sum lam ni hpe makawp maga ya lu ai.
6. Shiga jaw ai lam hte gram lajang ai lam hpe hpaji jaw ai lam ni
Hpang jahtum, jep joi ai lam a jahpan ni hpe kadun dawk tsun dan nna, n-gun n rawng ai lam, ngam nga ai magam bungli prat, gram lajang na matu ahkyak ai lam ni hpe asan sha tsun dan ai, hkrak tup ai shiga hpe shapraw ai. Scaling hte seng ai lam ni a matu, chemical hte ayan jasan jaseng na matu hpaji jaw da ai. Aten law law hka pru ai shara ni hta, kaja dik htum welding galaw ai ladat (sh) gram lajang da ai sealing arung arai ni ra ai.
Standardized jep joi ai lam gaw spiral heat exchanger ni a service prat hpe kaja wa jat ya lu nna, galaw shapraw ai ladat ni a akyu rawng ai hte shim lum ai hpe hkam la lu ai.
