1.1 Hka -Katsi ai Hkrang a Madung Daw ni hte Magam Bungli

Hka-katsi ai ladat gaw nbung hpe hkangzing ai ladat hta ahkyak dik htum rai nga ai. Shi a bungli gaw, ahkyak ai daw ni hku nna, katsi ai hpe shinggrup nna, jak kata kaw byin pru wa ai katsi ai hpe matut manoi shapraw kau na matu re. Standard system langai hta hka katsi ai hka tank, hka lim ai pump, hka pipe, katsi galai ai jak, filter, katsi ai hpe chye ai jak, solenoid valve ni lawm ai. Ndai daw ni gaw, matut manoi katsi ai hpe htawt sit ya lu ai, pat da ai-loop circulation system hpe hpaw ya ai.
Hpa majaw nga yang, n-gun rawng ai pump gaw, n-gun rawng ai hka hpe transformer hte power module ni hku nna shachyut ya ai. Katsi ai hpe hkap la nna, katsi ai hpe galai shai ai shara de htawt sit nna, shinggan grup yin de shapraw kau ai. Dai hpang, coolant gaw tank de bai nhtang wa nna, matut nna cycle galaw ai. Dai system hpe hkrak hkra galaw ai shaloi, kata na nbung katsi ai lam gaw ngang grin nga ai majaw, welding current hpe n galai shai ai sha, weld quality hpe mung ngang grin hkra galaw ya lu ai.
Hpaga lam hta, hpaji jaw da ai bungli galaw ai masa ni gaw lawu na hte maren rai nga ai:

• Hka shang ai hka katsi ai: 20-30 degree

Ndai shadawn shadang hta nbung laru shai hkat ai rai yang, hka lwi ai lam n law ai (sh) nbung galai shai ai lam yawm mat ai hpe madun ai. Industry data hku yu yang, coolant flow gaw rated capacity a 80% npu de hkrat mat ai shaloi, grai katsi wa na masa grai law wa ai. Katsi ai shara hta aten galu bungli galaw ai gaw IGBT module ni a asak hpe 30%–50% shayawm ya lu ai majaw, ndai gaw aten galu-arung arai ni hkrat sum ai lam a majaw byin pru wa ai lam langai mi rai nga ai.

1.2 Nbung -Katsi ai Hkrang a Karum Ai Lit

Hka-katsi ai ladat gaw, npawt nhpang katsi ai lit hpe hparan ya ai raitim, nbung-katsi ai ladat gaw ahkyak ai madi shadaw ai lit hpe gun hpai nga ai, grau nna, grup yin katsi ai lam grai law ai (sh) matut manoi galaw shapraw ai masa ni hta. Control cabinet kata na nbung katsi ai hpe ngang grin hkra galaw ya nna, hkam sha chye ai electronic arung arai ni a grup yin hta nbung katsi ai hpe pat shingdang ya ai.
Nbung-katsi ai ladat hta, nbung katsi ai nbung laru, nbung katsi ai shara, nbung lwi ai lam ni lawm ai. Dai gaw component ntsa nbung hpe shinggrup nna katsi ai hpe shapraw kau ya ai. Shi a katsi ai atsam gaw hka katsi ai hta grau yawm ai raitim, nbung katsi ai lam yawng hpe n-gun jaw na matu ra kadawn nga ai.
Field data hku yu yang, nhpu gaw heat sink a ntsa 30% jan hpe ka-up da ai shaloi, yawng hkra katsi ai atsam gaw 20% jan hkrat sum mat chye ai. Ndai lam gaw, nbung laru aten hta grai katsi ai alarm ni grau law ai a madung lam langai rai nga ai.
Dai majaw, nbung-katsi ai ladat hpe lahkawng ngu na daw hku n mai sawn la ai. Bungli galaw ai masa yawng hta ngang grin ai hku bungli galaw lu na matu hka-katsi ai ladat hte maren gram lajang ai aten ladaw hta lawm ra ai.

Hka-katsi ai ladat hpe gram lajang ai atsam gaw, medium-frequency spot welder langai aten galu laman kam hpa mai ai hku bungli galaw lu na hpe hkrak dawdan ya ai. Industrial makau grup yin law malawng hta, n-gun n rawng ai cooling system hpe n-gun n rawng ai majaw, n-gun grai ja ai hte n myit mada ai sha n-gun n rawng mat ai lam ni a madung lam gaw, jak rung ni hkum nan grai kaja ai aten hta pyi rai nga ai.

2.1 Shani shagu gram lajang ai lam: Shawng daw-Stage hkrat sum ai lam ni hpe pat shingdang ai lam

Shani shagu jep joi ai lam gaw, grai sawng ai hkrat sum lam ni de n byin shi yang, tau hkrau sadi jaw ai kumla ni hpe mu lu na matu yaw shada ai. Operator ni gaw, n-gun n-jaw shi yang, coolant level hpe jep yu ra ai. Coolant n law ai majaw pump kata de nbung shang wa nna, n ngang grin ai circulation byin wa chye ai. Ndai lam gaw kalang ta hkrat sum ai lam n byin shangun tim, dai zawn re ai masa hta aten galu galaw ai gaw, shara langai ngai hta grai katsi mat chye ai.

Coolant a masa hpe mung yu ra ai. Dai ntsin gaw sumwi zawn rai mat ai, nsam galai mat ai, shing nrai, nhprang wan n-gun rawng ai rai yang, dai gaw awu asin byin ai hpe madun ai majaw, katsi ai ntsin hpe kalang ta galai kau ra ai.

Leakage hpe jep yu ai lam gaw kaga ahkyak ai lahkam langai mi rai nga ai. Kalang lang hka pru ai shara ni hta pipe joint ni, pump matut mahkai ai lam ni, heat exchanger interface ni lawm ai. Kaji kajaw hka pru wa ai rai yang pyi, system a n-gun hte katsi ai atsam hpe loi loi hte shayawm kau ya lu ai. Aten na wa ai hte maren, ndai lam gaw thermal stability hpe grai hkra machyi shangun chye ai.

Dai hta n-ga, coolant lwi ai hpe mung sadi ra ai. Nbung n-gun (sh) n-gun n rawng ai lwi ai lam ni nga ai gaw, kata lam pat da ai (sh) nbung shang wa ai hpe law law lang madun ai. Ndai zawn re ai masa ni byin wa yang, bungli galaw ai shaloi nbung katsi ai lam lawan ai hku n byin hkra, dai system hpe jep yu na matu jahkring kau ra ai.

2.2 Aten kadun gram lajang ai lam: Aten galu-hpring tsup hkra galaw ai

Shani shagu jep joi ai lam hta n-ga, aten galu-system kam hpa mai ai lam hpe makawp maga na matu aten kadun laman gram lajang ai lam gaw ahkyak nga ai. Filter ni hpe bat shagu jasan jaseng ra ai, hpa majaw nga yang, shanhte gaw hka lwi ai lam hte katsi ai lam hpe shayawm ya ai nhprang arai ni hpe shinggyin la lu ai majaw re. Heat exchanger ni hpe mung ayan jasan jaseng ra ai, grau nna ga nhpu (sh) sau law ai shara ni hta jasan jaseng ra ai.
Shata shagu, circulation pump hpe n-gun n rawng ai, nsen n pru ai, shing nrai, bungli galaw ai lam hkra machyi ai hpe jep yu ra ai.

Pipeline aging hpe mung jep yu ra ai, hpa majaw nga yang, n-gun ja ai (sh) n-gun ja ai hose ni gaw, n-gun npu hta hka pru wa na masa hpe grai law hkra jat shangun ai.
Shata masum shagu, system hpe tup hkrak gram lajang na matu hpaji jaw da ai. Dai hta, hka lum ai ntsin hpe hka ja kau nna galai kau ai, tank hte pipeline ni hpe hka lim kau ai, nbung katsi ai hpe chye lu ai sensor ni hpe bai gram lajang ai lam ni lawm ai. N tara ai hku hti ai gaw aten dep system hpe makawp maga na matu pat shingdang lu nna, jak rung ni hkra machyi na masa hpe grau law hkra galaw ai majaw, nbung katsi ai hpe hkrak hkrak yu reng na matu ahkyak nga ai.

Hpa majaw nga yang, nbung-katsi ai ladat gaw, grau nna matut manoi bungli galaw ai aten (sh) katsi ai shara ni hta, cabinet kata na katsi ai hpe ngang grin hkra galaw na matu ahkyak ai lit nga ai. Nbung n kaja ai masa gaw, katsi ai hpe shinggyin la lu nna, electronic arung arai ni a kam hpa mai ai lam hpe shayawm kau ya lu ai.

Shani shagu gram lajang ai aten hta, nbung katsi ai shara ni hte nbung lwi ai lam ni hpe jasan jaseng na matu, compressed dry air hpe lang ra ai. Nbung hkrak hkra pru wa lu na matu, ga nhpu hte welding galaw ai nhprang arai ni hpe shaw kau ra ai. Hkai sun mahkrum madup hku yu yang, nbung lwi ai lam ni hpe 10 daram pat da ai shaloi, 1000 daram daram pat da ai.30%, katsi ai atsam gaw 1 hta jan nna hkrat sum chye ai.20%.

Fan bungli galaw ai hpe mung n kaja ai hku katsi ai, nsen n pru ai, n grin ai lawan ai lam ni hpe sadi maja ra ai. Ndai zawn re ai kumla ni byin wa yang, fan motor (sh) bearing ni gaw n-gun yawm mat ai majaw, n myit mada ai sha n-gun yawm mat na hpe koi lu na matu, alawan service (sh) galai ra ai.

Tengman ai galaw shapraw ai makau grup yin ni hta, grai katsi ai alarm (sh) n grin ai welding quality gaw wan n-gun n kaja ai lam ni hta grau nna, katsi ai system manghkang ni hte matut mahkai nga ai. Ana kumla ni hpe aten dep chye lu yang, bungli n galaw ai aten hte gram lajang ai manu hpe grai shayawm ya lu ai.

Masha law malawng mara ai hpe madung tawn ai table

Medium-frequency spot welder mari na matu masing jahkrat nga ai company ni a matu, katsi ai ladat hpe hkrang shapraw ai gaw, jak rung a kam hpa mai ai lam hpe madung madun ai lam rai nga ai. Machine law law gaw shawng nnan hta kaja ai hku galaw lu tim, matut manoi galaw shapraw ai npu hta, katsi ai atsam n law ai majaw, grai katsi ai lam ni byin pru wa ai.
