VI: Kev Xaiv Kev Ua Haujlwm
Cua Volume:Qhov ntim ntawm huab cua ncig ib lub sijhawm, chav tsev cubic meters / teev (CHM), cubic feet / feeb (CFM) m³ / h≈1.7CFM
Static Pressure:Lub siab exerted los ntawm cov pa ntawm qhov chaw ntawm ib yam khoom uas parallel rau lub airflow. Cias muab, static siab yog lub siab uas overcomes cov kuj ntawm cov kav dej.
Dynamic Siab:Kev hloov pauv ntawm lub zog kinetic xav tau rau cov roj ntws mus rau hauv siab. Hauv cov ntsiab lus yooj yim, dynamic siab yog lub siab uas ua rau lub zog txav mus tom ntej ntawm cov roj.
Tag Nrho Siab:Qhov sib txawv ntawm tag nrho cov siab ntawm lub qhov hluav taws xob ntawm lub kiv cua thiab tag nrho cov siab ntawm qhov inlet seem.
Tag Nrho Siab=Static Pressure + Dynamic Pressure
Cua ntim yog proportional rau dynamic siab.Qhov loj ntawm cov huab cua ntim, qhov me dua qhov siab zoo li qub. Qhov loj ntawm cov huab cua ntim, qhov me dua qhov siab zoo li qub.
Kev ua haujlwm tsis zoo yog hais txog tag nrho cov kev poob siab ntawm txhua qhov kev poob siab hauv qhov cua, nrog rau cov lim dej, evaporators, condensers, baffles, dampers, thiab cov kav dej ntawm txoj kev. Nws yog feem ntau zoo correlated nrog cov roj ntws los ntawm lub system. Cov kab hluav taws xob tiv thaiv kab ke raug qhia hauv qab no. Qhov chaw ua haujlwm ntawm tus kiv cua hauv qhov system yog txiav txim siab los ntawm kev sib tshuam ntawm qhov system tiv thaiv nkhaus thiab tus kiv cua airflow static siab nkhaus. Feem ntau, ua ke nrog cov kiv cua qhov kev ua tau zoo nkhaus, qhov chaw ua haujlwm tau teeb tsa ze ntawm qhov chaw ua haujlwm siab ntawm kev ua haujlwm nkhaus kom ua tau zoo tshaj plaws ntawm cov kiv cua thiab txuag lub zog..
VII: Kev tiv thaiv
Tam sim no txwv kev tiv thaiv
Lub cev muaj zog ntawm lub sijhawm saib xyuas lub tsheb npav tam sim no. Thaum lub load nce thiab DC lub tsheb npav tam sim no tshaj tus nqi teev tseg **A, nws nkag mus rau kev tiv thaiv tam sim no. Thaum lub load txo, nws maj mam tawm tam sim no txwv kev tiv thaiv. Kev tiv thaiv kev txwv tam sim no yog siv los ntawm kev txo lub voj voog lub luag haujlwm (qhov muaj zog ntawm qhov winding). Yog li ntawd, yog hais tias lub load yog tshwj xeeb tshaj yog hnyav, nkag mus rau tam sim no txwv kev tiv thaiv tej zaum yuav ua rau qhov tseeb ceev yog qis dua lub teeb ceev.
Kev tiv thaiv overcurrent
Thaum muaj FO tiv thaiv (theem luv luv Circuit Court, thiab lwm yam) teeb liab, lub cev muaj zog tam sim ntawd nres rau kev tiv thaiv. Tom qab qhov kev ua txhaum raug tshem tawm rau 30s, yog tias cov khoom siv hluav taws xob thiab cov cim qhia tau zoo, lub cev muaj zog rov pib dua.
Kev tiv thaiv overtemperature
Lub rooj tsav xwm tswj lub cev muaj zog nruab nrog lub ntsuas kub ntsuas NTC ze ntawm IGBT txoj haujlwm. Thaum NTC hnov qhov kub txog li 100 degree, lub cev muaj zog nres rau kev tiv thaiv. Tom qab lub cev muaj zog nres, qhov kub thiab txias maj mam txo. Thaum NTC hnov qhov kub txog li 80 degree, yog hais tias lub hwj chim mov thiab hais kom ua teeb liab zoo li qub, lub cev muaj zog restarts.
Xauv Rotor Tiv Thaiv
Thaum lub cev muaj zog pib, nws yuav txiav txim siab seb nws puas raug kaw. Yog hais tias lub cev muaj zog kaw, lub cev muaj zog yuav nres rau 3s. Yog tias muaj 0-10VDC teeb liab, nws yuav rov pib dua. Yog tseem muab xauv, nws yuav nres rau lwm 3s. Yog tias nws tseem kaw thiab muaj qhov siv tau 0-10VDC teeb liab, nws yuav rov pib dua. Yog tias nws txuas txuas ntxiv peb zaug, lub cev muaj zog yuav nres rau 3 feeb. Yog tias muaj qhov siv tau 0-10VDC teeb liab, lub voj voog no yuav txuas ntxiv mus.
Tsawg Voltage Stop Protection, Overvoltage Stop Protection
Thaum lub cev muaj zog tshaj qhov voltage ntau, nws nres khiav thiab rov qab mus rau qhov qub pib nyob rau hauv qhov voltage range.
Input Fais Fab Kev Tiv Thaiv
Rau peb-theem fais fab mov, yog tias ib lossis ob theem raug txiav, lub cev muaj zog nkag mus rau theem poob nres. Thaum lub zog tawm tswv yim zoo li qub, lub cev muaj zog rov pib dua.
0-10V ceev tswj:Nws yog ib txoj kev tswj hwm qhov hluav taws xob uas siv los tswj kev ceev ntawm cov motors lossis lwm yam khoom siv hluav taws xob. Lub hauv paus ntsiab lus yog hloov cov zis hluav taws xob los yog ceev ntawm lub cuab yeej los ntawm kev kho qhov loj ntawm qhov input voltage. Nyob rau hauv {{0}}V ceev tswj qhov system, ib tug maub los feem ntau yog siv los tsim ib tug 0-10V tso zis teeb liab, uas yuav txuas mus rau lub tswj Circuit Court ntawm lub cev muaj zog los yog ntaus ntawv. Thaum tus maub los tso tawm 0V, qhov ceev lossis lub zog ntawm lub cuab yeej yog qhov tsawg kawg nkaus; Thaum tso zis 10V, qhov ceev lossis lub zog yog nyob ntawm nws qhov siab tshaj plaws. Los ntawm kev kho qhov tso zis voltage ntawm tus maub los, kev tswj ceev ceev ntawm lub cuab yeej tuaj yeem ua tiav. 0-10V ceev tswj qhov system muaj qhov zoo xws li qhov dav dav, kev tswj ceev ceev, thiab cov lus teb ceev ceev, ua rau nws tsim nyog rau cov xwm txheej uas xav tau kev kub ceev, xws li conveyor siv thiab cov neeg hlau ntawm cov kab ntau lawm.
PWM Speed Control:Nws ua tiav qhov ceev tswj kev ua haujlwm ntawm lub cev muaj zog lossis cov khoom siv hluav taws xob los ntawm kev kho lub luag haujlwm lub voj voog ntawm Pulse Width Modulation (PWM) teeb liab. Lub hauv paus ntsiab lus ntawm PWM ceev tswj yog siv ceev ceev hloov PWM teeb liab los tswj qhov ceev lossis ci ntsa iab ntawm lub cev muaj zog lossis cov khoom siv hluav taws xob. Los ntawm kev kho lub voj voog lub luag haujlwm ntawm PWM teeb liab, uas yog qhov sib piv ntawm lub sijhawm ntawm qib siab mus rau tag nrho lub sijhawm, qhov loj ntawm cov zis theem tuaj yeem tswj tau, yog li ua tiav kev tswj ceev. Hauv PWM ceev tswj, qhov sib txawv ntawm lub voj voog ua haujlwm feem ntau yog los ntawm 0% mus rau 100%. Lub voj voog lub luag haujlwm loj dua, qhov siab dua qhov tso zis ntau dua, thiab ntau dua qhov ceev lossis ci ntsa iab ntawm lub cev muaj zog lossis cov khoom siv; rov qab. Kev tswj ceev ceev ntawm lub cev muaj zog lossis cov khoom siv tuaj yeem ua tiav los ntawm kev kho lub luag haujlwm lub voj voog ntawm PWM teeb liab, muab qhov tseeb ceev tswj cov teebmeem. PWM ceev tswj tau dav siv nyob rau hauv ntau yam kev tswj lub cev muaj zog, xws li DC motors, stepper motors, brushless DC motors, thiab lwm yam.
RS485 Ceev Tswj:Nws ua tiav kev tswj ceev siv RS485 kev sib txuas lus raws tu qauv. RS485 yog ib qho kev sib txuas lus sib txuas lus sib txuas lus uas txhawb nqa ntau yam khoom siv sib txuas lus ntawm tib kab kev sib txuas lus ib txhij. Hauv RS485 tswj ceev, feem ntau muaj cov cuab yeej zoo thiab ntau yam qhev. Tus tswv ntaus ntawv yog lub luag haujlwm xa cov lus txib tswj ceev mus rau cov qhev pab kiag li lawm, uas tau txais thiab ua raws li cov lus txib no. Cov kauj ruam ntawm RS485 ceev tswj muaj xws li: 1. Tus tswv ntaus ntawv xa ceev tswj commands rau cov qhev pab kiag li lawm, feem ntau yog siv ib tug tshwj xeeb cov ntaub ntawv thav duab hom los sawv cev rau cov ceev tswj hais kom ua. 2. Cov cuab yeej qhev ua haujlwm tswj ceev raws li cov lus txib tau txais. 3. Tus qhev ntaus ntawv xa cov txiaj ntsig tswj kev ceev rov qab mus rau tus tswv ntaus ntawv, feem ntau yog siv cov ntaub ntawv tshwj xeeb thav duab los sawv cev rau kev tswj ceev. 4. Tus tswv cuab yeej, thaum tau txais qhov tshwm sim, tuaj yeem siv cov kev ntsuas tsim nyog raws li qhov xav tau, xws li kev hloov kho ceev tswj cov lus txib lossis tso saib cov txiaj ntsig tswj ceev.
