Engineer law law gaw, blueprints ni hpe hkap la ai shaloi, arung arai ni hpe tam na matu hprawng hkawm ma ai, raitim, hpaw da ai katsi ai nta langai a matu, hkrak ai shara hpe lata ai gaw, teng sha grai sawng ai lam ni hpe hkam la lu ai. Ngai dum ai gaw, nta npawt hpe bungli galaw ai shara langai a shinggan bunghku makau kaw nan jung da ai project langai mi hpe ngai dum ai. Dai majaw, katsi ai hte hka lim ai nbung gaw shata kru laman bunghku ntsa e hka lim ai lam byin wa nna, shinggan bunghku hpe n-gun shayawm ya ai. Ya ngai hkrum sha nga ai mahkrum madup gaw, n law htum metre 1.5 daram gram lajang ai lam hpe tower grup yin hta gram lajang ra ai, dai hta n-ga, 5 metres ntsa kaw nna pat shingdang ai lam n nga ra ai (nbungli conditioner shinggan unit zawn re ai). Tower hpe nta ntsa kaw jung da ai rai yang, nbung hpe ninghkap lu ai coefficient hpe myit yu ra ai. Metre 30 jan tsaw ai nta ni a matu, nbung n-gun hpe shayawm na matu hpaji jaw ai.

Npawt nhpang ru bang ai shaloi, n yu n hkan galaw ai lam ni law law nga ai gaw, concrete grade gaw C25 hta grau kaba ai (sh) maren sha rai ra ai, embedded steel plates ni a madang hpe ±2mm kata kaw hkang zing ra ai. Lai wa sai shaning hta, bungli masing langai hpe hkap la ai lam hpe jep joi ai lam galaw ai shaloi, anhte gaw npawt nhpang madang hta 5mm deviation hpe mu tam wa ai majaw, bungli galaw ai shaloi, shayawm ai jak hpe n kaja ai hku n-gun jaw ai majaw, bai bungli galaw ra ai. Piping matut mahkai lam ni hpe mung atsawm sha myit yu ra ai. Dai hpe hka lum ai hka shang ai pipe ntsa hta Y{{6} zawn re ai filter ( Greater hta grau nna (sh) dai hte maren) hpe bang na matu hpaji jaw da ai. N rai yang, hka lim ai hka hta slag hte rust hpe welding galaw ai gaw, spray pipe ni hpe lawan ladan pat kau ya na re.

II. Komishin Phase: Ndai parameters ni gaw laika buk hta grau ahkyak ai.

Shawng nnan na commissioning gaw teng sha hpaji bungli langai mi re. Ngai hpe myit n pyaw shangun ai mabyin langai: customer langai mi, self{1}}commission galaw ai aten hta, fan hpe throttle hpring tup galaw nna, 0.8% daram hka lim ai lam byin wa ai (normally, dai gaw rai ra ai.<0.01%). It was later discovered that the fan inverter's startup ramp was set too steeply, resulting in uneven airflow distribution. My current commissioning process is: first, start the circulating water pump and run it for 30 minutes. Observe the water level in the collection pan for stability (normal fluctuation range: ±5mm). Then, gradually increase the fan speed. Simultaneously, use an infrared thermometer to monitor the temperature difference between the inlet and outlet water of the coils. High-quality equipment should maintain a steady temperature difference of 5-8°C.

Hka a hkamja lam hpe hparan ai lam hpe shawng nnan shani kaw nna ahkyak shatai ra ai. Laika man mill galaw ai masing gaw, kalang ta antiscalant hpe n jat bang ai majaw, shata masum na ai hpang 1.2mm galu ai copper pipe scale hpe shinggyin la lu ai majaw, katsi ai galai shai ai atsam hpe jahkring kau lu ai. Dai gaw, hka lum ai hka htung hta online conductivity meter (control range range) hpe bang na matu hpaji jaw da ai. 2000μS/cm jan ai shaloi, bypass filter system hpe galaw ra ai. Katsi majan aten hta bungli galaw ai aten hta frost makawp maga na matu laksan myit maju jung ra ai. Lai wa sai shaning hta, Miwa mung Sinpraw Dingda maga na masing langai mi gaw, coil ni hpe tsep kawp n hka n htum ai majaw, -25℃hta titanium pipe masum katsi mat nna, n-gun yawm mat ai. Dai gram lajang ai lam hpe yuan 80,000 jan jai lang ra ai.

3. Magam bungli hte gram lajang ai lam: Ndai "nta-tsu" ladat ni gaw, jak rung ni hta grau nna akyu rawng ai.

Shani shagu jep joi ai lam ni gaw asan sha hte akyu rawng ai "madat ai masum, langai mi hpe yu ai" mantra hpe lang ai: n bung ai fan nsen ni hpe madat ai ( metallic friction nsen gaw n hkra hkra, n-gun n rawng ai nsen langai mi nga ai); hka lim ai pump hta cavitation nsen ni hpe madat u (a "clattering" nsen); shayawm ai arung arai ni a nsen hpe madat u (normal nsen gaw n-gun n rawng ai "hum" rai ra ai); hte hka hpe shinggyin la ai hka htung kata na hka hpe turbidity nga ai kun ngu jep yu u (dai gaw asan sha rai nna mu lu ai rai ra ai). Chemical wan jak kaw na operator langai gaw PVC pipe hpe lang nna nta kaw galaw ai sampler langai hpe galaw shapraw ai. Shanhte gaw bat shagu sediment ni hpe shinggyin la nna, laboratory chyam dinglik ai hta grau nna manghkang ni hpe yu ai.

Cleaning packing gaw grai hpaji rawng ai bungli langai mi re. Hkamja lam hpe gram lajang ai masha law law gaw, PVC n-gun n rawng ai hka htung hpe n-gun n rawng hkra galaw ya lu nna, nbung lwi ai lam hpe shayawm ya lu ai, tsaw ai{1}}} pressure hka jet ni hpe lang ma ai. Teng man ai ladat gaw, packing hpe n-gun n rawng ai-bristed brush hte neutral detergent hte hkying hkum lahkawng tup lup nna, n-gun n law ai hka hte kashin kau na ( 0.3 MPa hte maren 0.3 MPa) hte hka hte kashin kau na. Lai wa sai shaning hta, anhte a san seng ai lam hpe grau kaja hkra galaw ya ai, hka hpe shinggyin la ai pan hta automatic dosing device langai hpe jung da ai, n-gun shayawm ai lam ni hpe ayan jat bang ai. Ndai lam gaw packing prat hpe masum ning kaw nna manga ning de jat wa shangun ai.

IV. Upgrade hte Retrofits ni: Moi na arung arai ni hpe pyi lahkawng lang na prat hpe lu la mai ai

Anhte hkrum katut ai grau nna yak hkak ai bungli masing gaw, 12-old galvanized hpri n-gang hpe n-gun n rawng ai n-gang de galai shai ai lam rai nga ai. Shawng nnan na arung arai ni a n-gang n-gang hpe grai hkra machyi shangun ai. Anhte gaw "local reinreverement + yawng hkra n-gun n-gun hpe makawp maga ai lam" hpe hkan sa ai: npawt nhpang npawt nhpang hpe n-gun jaw ai raitim, carbon steel liner ni hpe jat bang ai, spray system hpe galai nna 316L stainless steel hte packing galaw ai. Retrofit gaw nbung galai shai ai atsam hpe 25% jat ya nna, shaning shagu na gram lajang ai manu hpe 40% shayawm ya ai. Ndai mabyin gaw, myit sawn sumru ai lam hpe bai gram lajang ai hku nna, arung arai dingsa ni gaw, ladat nnan ni hpe hkum tsup hkra galaw lu ai hpe madun dan nga ai.

Hpaji rawng ai hkang zing ai ladat ni hpe gram lajang ai gaw, n myit mada ai akyu ni hpe law law lang jaw ya ai. Lai wa sai shaning hta, anhte gaw IoT- kaw na yu reng ai ladat hpe data center langai mi hta jung da ga ai. Hka lum ai hte shinggan de na hka n-gun, fan ni a n-gun, hka lwi ai lam ni hta tengman ai- aten jahpan ni hpe shinggyin la lu ai hku nna, jak hpaji sharin ai ladat hte rau, anhte gaw scaling masa ni hpe tau hkrau tsun dan nna, tsi htu ai aten hpe proactive hku gram lajang ai, dai gaw jak rung ni hkrat sum ai n-gun hpe 60% shayawm ya lu ai. Grau nna myit yu hpa gaw, coil lwi ai hpe yu na matu ultrasonic flowmeter hpe jung da ai lam re. Hka lim ai lam n kaja ai hku hkrat sum mat ai shaloi, pat shingdang ai lam ni hpe tau hkrau sadi jaw ai lam hpe jaw ya lu ai-}th gaw, manghkang hpe n hparan shi yang, katsi ai galai shai ai atsam yawm mat ai aten du hkra la nga ai hta grau loi ai.

Ngut nna tsun ga: Mahkrum madup gaw kaja dik ai sara re

Hpaw pat da ai katsi ai nta gaw, npawt nhpang hta asan sha rai na re, raitim, galu kaba ai- aten galu ai bungli hpe matut manoi galaw na matu, sung sung li li mahkrum madup law law ra ai. Kalang mi ngai hpe customer langai ngai ngai hpe san ai hpe ngai dum ai, "Nang galoi mung n-gun jaw ai arung arai ni gaw hpa majaw lahkawng masum ning galu ai kun?" Ngai a mahtai gaw, "Hpa majaw nga yang, anhte gaw ga san hpe galoi mung ‘hpa majaw' ngu ai ga san hpe, garan ginhka ai lam shagu hta san ai." Dai hpang jahtum na greaas laika buk ni gaw, hpang jahtum na- n re ai gram lajang ai lam ni, dai data spreadsheet ni gaw, bai kahtap nna chyam dinglik ai hte record galaw ai kaw na, hpang jahtum e, manghkang hparan ai shaloi, ngai lang ai, hkam sha lu ai tara jeyang ai lam tai wa sai.

Hpang jahtum, tatut galaw mai ai hpaji jaw ga: Hka lum ai nta hpe hkang ai cabinet hta malu masha n-gun n rawng ai baw hpe galoi mung tawn da u. Ambient humidity gaw 85% jan ai shaloi, wan n-gun a daw ni a makau kaw tawn da u. Ndai lam gaw condensation- a majaw kadun ai circuit ni hpe hkrak hkra pat shingdang ya ai. Ndai ladat gaw 5 ning tup bungli galaw wa sai, ngai gaw contactor langai mi mung wan hkru ai lam n galaw yu ai. O&M hta shortcut ni n nga ai, raitim "n myit mada ai" shagu hpe "know- how" de galai shai kau ai gaw mahkrum madup a manu rai nga ai.
