Nsɛntitiriw a Wɔde Yɛ Adwuma Wɔ Closed Circuit Cooling Towers

 

Adwumayɛ a ɛyɛ den ne dwumadie nkwa nna a ɛwɔ closed circuit cooling towers mu no gyina standardized start-up ne closed, hwɛ pɛpɛɛpɛ, nsuo yiedie sohwɛ, mmerɛ mu ahobanbɔ, ne daa nsiesie. Wɔakyerɛkyerɛ adwumayɛ ho nsɛm atitiriw no mu wɔ ase ha.

 

 

 

 

 

 

 

 

1. Nhwehwɛmu a Ɛkɔ Akyiri Ansa na Woafi Ase

 

 

Nhyehyɛe ne Nsuo afiri a Wɔde Hwɛ Nneɛma So: Hwɛ sɛ abantenten no akorade ne nea ɛboa no sɛe anaasɛ asɛe anaa. Hwɛ sɛ fan ne motor ahobammɔ mfiri no nni dɛm. Hwɛ sɛ wɔde nsuo afiri a ɛkɔ mu/firi mu no abɔ mu yie, valve ahodoɔ no yɛ adwuma yie, nsuo a wɔde yiyi mu no ho tew na biribiara nsiw kwan, na nsuo afiri no nhyɛaseɛ no gyina hɔ pintinn na amma nsuo a ɛfiri adwumayɛ mu wosow mu ba no ano.

 

System Venting ne Nsu a Wɔde Ma: Bue mframa a ɛkɔ mframa mu no mu na yi mframa fi nsu a ɛkyinkyini ne nsu a wɔde petepete so no mu koraa na woakwati mframa a ɛko tia a ɛtew ɔhyew a wɔsesa no yiye so. Hwɛ nsuo dodoɔ a ɛwɔ sump no mu na fa float valve anaa automatic makeup so sesa no kɔ standard level no so na amma pump dry running anaa overflow.

 

Electrical ne Ahobammɔ Ho Nhwehwɛmu: Si so dua sɛ motor wiring no yɛ nea ahobammɔ wom, grounding yɛ nea wotumi de ho to so, na insulation resistance du gyinapɛn ahorow ho. Hwɛ sɛ nnwinnade ne akanea a ɛkyerɛ biribi a ɛwɔ control panel no so no kyerɛ no yiye na switch ahorow no yɛ adwuma yiye. Popa nneɛma a asɛe a atwa abantenten no ho ahyia no ho na amma nneɛma a ɛyɛ ananafo ankɔ fan anaa aduru a wɔde petepete so no mu.

 

Medium Compatibility Confirmation a ɛkyerɛ sɛ ɛyɛ nea ɛfata: Hwɛ sɛ nsuo a ayɛ nwini no ne coil adeɛ no hyia (sɛ nhwɛsoɔ no, wɔabara kɔbere nsuo a wɔde yɛ ammonia media) na amma nnuru ansɛe, antu, anaa coil no antumi apaapae.

 

 

2. Pɛpɛɛpɛ Monitoring ne Operation Bere a Mmirikatu

 

 

 

Strict Startup/Sutdown Ntoatoaso: Di kan fi ase nsu pɔmpɛ a ɛkyinkyini no. Sɛ nhyehyɛe no ayɛ ma na mframa afi mu a, fi ase fan no. Sɛ wopɛ sɛ woto mu a, di kan gyae fan no, afei gyae pɔmpɛ no wɔ simma 10–15 ntam akyi na ama coil no ayɛ nwini sɛnea ɛsɛ na woakwati ɔhyew a ɛde ahopopo no sɛe.

 

Core Parameter a Wɔhwɛ So: Ma nsu a ɛkɔ mu/fi mu no hyew mu nsonsonoe nkɔ so nyɛ digrii 5–15 . Nsonsonoe ketewaa bi taa kyerɛ sɛ efĩ anaasɛ adwumayɛ so tew; nsonsonoe kɛse kyerɛ sɛ wɔde nneɛma boro so. Hwɛ nsu a ɛkyinkyini no nhyɛso so: sɛ ɛba fam mpofirim a, ɛkyerɛ sɛ nsu retu, bere a sɛ ɛkɔ soro mpofirim a, ɛtaa kyerɛ sɛ filter no asiw. Hwɛ sɛnea aduru a wɔde petepete so no yɛ pɛ na ama woahwɛ ahu sɛ nozzle no nsiw na ɛkata coil no so koraa.

 

Nsuo Pa Ho Nsɛm a Wɔhwɛ So: Sɔ pH (6.5–8.5), sɛnea ɛyɛ den, sɛnea ɛtumi fa mu, ne mmoawa nketenkete a ɛwɔ mu hwɛ daa. Fa nnuru a esiw nsɛe ano, nnuru a esiw nsensanee ano, ne nnuru a ekum mmoawa ka ho na amma nsensanee, nsɛe, ne atɛkyɛ nnyin. Hohoro nneɛma a ɛsensɛn nsu mu wɔ sump no mu dapɛn biara na fa petepete filters so ɔsram biara na amma nozzle no ansiw.

 

Fan ne Drive Nhwehwɛmu: Tie dede anaa wosow a ɛnyɛ ne kwan so. Hwɛ sɛnea abɔso no mu yɛ den ɔsram biara. Hwɛ motor ne bearing hyew (<=75℃) na fa high-temperature grease gu so asram asia biara na ama woahwɛ ahu sɛ ahoɔden kari pɛ yiye.

 

 

 

3. Bere mu Ahobammɔ

 

 

 

Awɔw Bere mu Nwini Ho Banbɔ (Ɛho Hia) .: Oprehyɛn a wɔkɔ so yɛ no ne ade a eye sen biara a wɔde siw awɔw ano. Sɛ wopɛ sɛ woto mu bere tenten a, yi nsuo fi coils, spray system, ne pipelines mu koraa, na fa mframa a wɔahyɛ no den tew nsuo a aka no ho. Fa anyinam ahoɔden a wɔde hwehwɛ ɔhyew a wɔde hwehwɛ nneɛma mu ne nneɛma a wɔde siw abɔnten nsu afiri ano gu mu. Fa ethylene glycol aduru a ekum nwini di dwuma sɛ ɛho hia a.

 

Ahuhuro a Ɛkorɔn-Ɔhyew Dwumadi: Ma mpɛn dodow a wɔhwehwɛ nneɛma mu nkɔ soro na fa w’adwene si motor no hyew so. Siesie mframa a ɛkɔ mu ne coil no ani na ama mframa a ɛkɔ mu ne ɔhyew a wɔde sesa no atu mpɔn. Ma nsu a wɔde petepete so no nkɔ soro wɔ ɔhyew a ɛkɔ soro kɛse mu na amma ɔhyew a ɛboro so no adum.

 

 

 

4. Daa Siesie ne Shutdown Ɔhwɛ

 

 

 

Nsiesiei Nhyehyɛe: Hwɛ nsu dodow, ne su, ne dede a ɛnteɛ dapɛn biara. Siesie afiri a wɔde yi nsu mu, bue nsu a ɛwɔ nsu mu no, na kyekye anyinam ahoɔden nhama no mu den ɔsram biara. Fa nsu a ɛba fam-nhyɛso hohoro coils ho asram abiɛsa biara, hwɛ fan blade balance ne gearbox oil level. Yɛ nnuru a wɔde tew ho afe biara, hwɛ sɛ coil no asɛe na ɛretu, na sesa nsɔano ne bearing a akyɛ.

 

Bere Tenten-Mmere a Wɔde Tow Nneɛma Mu Ho Nhyehyɛe: Yi nsu nyinaa, tew emu nneɛma a asɛe no ho. Fa nkataso a ɛbɔ fan ne mframa a ɛkɔ mu ho ban hyehyɛ mu na amma mfutuma ankɔ mu. Twa anyinam ahoɔden na bɔ unit no ho ban yiye. Tia pre-fiase nhwehwɛmu no nyinaa mu ansa na wode adi dwuma bio.

 

 

 

 

5. Ahobanbɔ ne Ahoɔden-Akoraeɛ ho nsɛm

 

 

Fa ahobammɔ ho nsɛnkyerɛnne sisi unit no ho na fa lockout–tagout nhyehyɛe ahorow di dwuma bere a wɔresiesie no. Fa variable frequency drives di dwuma na ama fan ne pump ahoɔden ne thermal load ahyia. Wɔ mmere a ɔhyew a ɛba fam-mu no, wobetumi adum aduru a wɔde petepete so no ama dry-adwumayɛ kwan so de atew ahoɔden a wɔde di dwuma no so.
