Thaum xaiv qhov siab - kiv cua kev daws teeb meem rau AHU lossis HVAC retrofit project, cov kws ua haujlwm feem ntau ntsib nrog kev txiav txim siab -VSD plug kiv cualos yogEC plug kiv cua. Ob leeg yog rov qab nkhaus centrifugal kiv cua ntsia tsis muaj casings (plug- kiv cua style), thiab ob qho tib si muaj kev sib txawv - cua nrawm. Yog li qhov twg zoo dua? Cov lus teb yog nyob rau hauv kev ua tau zoo, kev sib txuas ntawm kev sib txuas, kev saib xyuas, thiab kev ua haujlwm ntev - tus nqi ua haujlwm.
Hauv qab no, peb piv VSD (Variable Speed Drive) plug kiv cua thiab EC (Electronically Commutated) plug kiv cua los pab koj xaiv qhov kev paub. Peb kuj tseem yuav siv peb cov 355mm rov qab centrifugal ntxuam, 400mm EC rov qab nkhaus centrifugal ntxuam, thiab EC axial kiv cua qauv kom yooj yim rau kev sib txuas.
VSD Plug Ntxuam yog dab tsi?
VSD plug ntxuam yog ib qho rov qab nkhaus centrifugal ntxuam (feem ntau ntsaws-mounted) ua ke nrog lwm qhov hloov pauv ceev (VSD). Lub cev muaj zog yog ib txwm AC induction lub cev muaj zog, thiab VSD yog siv los kho zaus thiab qhov hluav taws xob kom sib txawv ntawm cov cua.
Yam ntxwv:
- AC lub cev muaj zog + VSD sab nraud
- Ntau txoj kab hluav taws xob (lub zog + tswj cables)
- Zoo rau retrofit tej yaam num uas sab nraud drives twb muaj lawm

EC Plug Ntxuam yog dab tsi?
EC plug ntxuam kuj tseem siv lub zog rov qab nkhaus centrifugal impeller, tab sis yog siv los ntawm kev sib xyaw EC lub cev muaj zog (brushless DC nrog ua - hauv maub los). Tsis muaj VSD cais yuav tsum tau - ceev yog hloov ntawm yooj yim 0–10 V lossis Modbus teeb liab.
Yam ntxwv:
Ua- hauv inverter & ceev tswj
Plug-thiab- ua si txuas
High zog efficiency (txog 90%)
Muaj nyob rau hauv cov ntaub ntawv compact xws li400mm EC rov qab nkhaus centrifugal ntxuamlos yog250mm EC axial ntxuam
VSD vs EC Plug Ntxuam - Kev sib piv ntxaws
| Feature | VSD Plug Ntxuam | EC Plug Ntxuam |
|---|---|---|
| Hom Tsav | AC lub cev muaj zog | EC brushless DC lub cev muaj zog |
| Tswj ceev | External VSD yuav tsum tau | Ua - hauv kev tswj hluav taws xob |
| Kev Siv Hluav Taws Xob | Siab dua (hwj chim + tswj thaiv kev sib cais tsav) | Yooj yim ntsaws-thiab- ua si |
| Zog Efficiency | Nruab nrab (60-70%) | Siab heev (80–90+%) |
| Hneev taw | Yuav tsum muaj chaw rau VSD cais | Compact tag nrho -hauv-ib tus kiv cua module |
| Tus nqi pib | Tsawg tus nqi tsav tsheb, ntxiv rau tus nqi tsav tsheb | Me ntsis siab dua, tsav nrog |
| Ntev - Tus Nqi Sij Hawm | Kev siv hluav taws xob ntau dua, kev saib xyuas ntau dua | Lower OpEx, kev saib xyuas tsawg |
Qhov twg zoo dua?
Xaiv EC Plug Ntxuam yog tias koj xav tau:
- Kev txuag hluav taws xob siab tshaj plaws thiab lub sijhawm them rov qab sai tshaj plaws
- Ib qho yooj yim installation tsis muaj lwm tsav
- Ua haujlwm ntsiag to ntawm ib feem load
- Ntse nta thiab BMS kev koom ua ke
-> e.g., a 400mm EC rov qab nkhaus centrifugal ntxuamsiv los ua tus kiv cua ntsaws hauv lub ru tsev AHU
Xaiv VSD Plug Ntxuam yog tias koj xav tau:
- Txhawm rau rov- siv VSD kho vajtse uas twb muaj lawm hauv cov haujlwm ua haujlwm rov qab
- Tus nqi qis dua lub cev muaj zog yog tias tus nqi hluav taws xob tsis tseem ceeb
- Flexibility rau khub nrog ntau hom tsav tsheb

Tej kev siv
| Hom ntawv thov | Pom zoo kiv cua daws |
|---|---|
| Lub zog tshiab-txuag AHU tsim | EC plug ntxuam (EC rov qab nkhaus centrifugal ntxuam) |
| HVAC retrofits nrog VSD uas twb muaj lawm | VSD ntsaws ntxuam siv rov qab centrifugal ntxuam |
| Compact cua purification units | EC axial kiv cua los yog me me EC plug ntxuam |
| Conveyor cua muab / rho tawm | Rov qab centrifugal ntxuam (AC lossis EC raws) |

Txawm hais tias ob qho tib si VSD thiab EC plug kiv cua muab qhov sib txawv ntawm huab cua tswj, EC plug ntxuam muab kev ua haujlwm zoo dua qub, kev teeb tsa yooj yim dua, thiab lub neej qis dua -cov nqi voj voog, ua tsaug rau nws cov khoom siv hluav taws xob sib xyaw thiab tsim qauv ntse. VSD plug kiv cua kuj tseem yuav pab tau rau hauv cov haujlwm tshwj xeeb retrofit qhov twg cov tsav sab nraud twb muaj lawm thiab hneev taw tsis muaj kev txhawj xeeb.
Yog tias koj lub hom phiaj yog tsim kom muaj kev ua haujlwm siab - ua haujlwm tau zoo, qis- suab nrov, ntseHVAC systems, EC plug kiv cua - xws li peb 400mm EC rov qab nkhaus centrifugal ntxuam los yog EC axial kiv cua series - yog qhov kev xaiv.
