Kuthamanga kwamadzi nthawi zonse

(HVAC, madzi am'tawuni, madzi othamanga nthawi zonse kumabizinesi amakampani)

Pakukula ndi kukhwima kwaukadaulo wowongolera magalimoto osinthika, njira zoyendetsera madzi (jakisoni wamadzi) nthawi zonse m'mizinda ndi mabizinesi akumafakitale atha kukwaniritsa ntchito mwanzeru, kupulumutsa mphamvu, kuchepetsa mtengo, kukonza magwiridwe antchito komanso kudalirika. Pakadali pano, mayiko otukuka akumadzulo motsogozedwa ndi United States akugwiritsa ntchito njira yoperekera madzi yanzeru nthawi zonse motsogozedwa ndi ma motors osinthika, kuyambira pakumanga HVAC kupita kumadzi am'mafakitale, ndikulumikizana ndi nsanja zamtambo kuti akwaniritse kupulumutsa mphamvu kwapachaka. mlingo Anafika 45%, ndipo kwenikweni anazindikira mosayang'aniridwa.

1. Basic hardware zikuchokera ndi ntchito ya switched kunyinyirika nthawi zonse kuthamanga madzi dongosolo

1. Anasintha kukana galimoto

Bwezerani injini yoyambirira ndi injini yosinthika yosinthika kuti muyendetse pampu yamadzi. Ubwino wake akufotokozedwa pambuyo pake.

2. Anasintha kusafuna galimoto wanzeru Mtsogoleri

Woyang'anira wanzeru amayendetsa galimoto yosinthika yosafuna kuyendetsa mpope kuti ayendetse, amalankhulana ndi PLC ndi sensa yamphamvu mu nthawi yeniyeni, ndikuwongolera momasuka kuthamanga kwa linanena bungwe, torque ndi zinthu zina za injini yosinthira kukana;

3. Pressure transmitter

Amagwiritsidwa ntchito kuyang'anira kuthamanga kwenikweni kwa madzi a netiweki ya chitoliro mu nthawi yeniyeni ndikutumiza deta kwa wolamulira wanzeru wagalimoto.

*4.PLC ndi zigawo zina

PLC imagwiritsidwa ntchito poyang'anira dongosolo lonse lapamwamba. Zida zina zofunika ndi masensa, monga ma transmitters amadzimadzi, nsanja zowunikira, ndi zina zambiri, zimachulukitsidwa kapena kuchepetsedwa malinga ndi zosowa za machitidwe osiyanasiyana.

2. Mfundo yofunikira yosinthira kusafuna madzi nthawi zonse

Kusintha kwenikweni kwa kukakamiza mu maukonde a chitoliro chamadzi omwe amatsogolera kwa wogwiritsa ntchito amasonkhanitsidwa kudzera mu sensa yamagetsi ndikuperekedwa kwa wowongolera wanzeru. Wowongolera amafanizira ndikuwongolera ndi mtengo womwe wapatsidwa (mtengo wokhazikitsidwa), ndikuwusintha molingana ndi zotsatira zakusintha kwa data. Zotulutsa monga liwiro la mota (pampu). Pamene kuthamanga kwa madzi kumakhala kotsika kusiyana ndi kukakamiza kokhazikitsidwa, wolamulira adzawonjezera kuthamanga kwa ntchito, ndi mosemphanitsa. Ndipo kudzisintha kosiyana kumachitidwa molingana ndi liwiro la kusintha kwamphamvu. Dongosolo lonse likhoza kutsekedwa-loop automatic control, ndipo liwiro la galimoto lingathenso kusinthidwa pamanja.

3. Ntchito zoyambira za dongosolo loperekera madzi nthawi zonse

(1) Sungani kuthamanga kwa madzi kosalekeza;

(2) Dongosolo loyang'anira limatha kusintha / kusintha pamanja ntchito;

(3) Makina osinthira opangira mapampu angapo;

(4) Dongosolo limagona ndikudzuka. Dziko lakunja likasiya kugwiritsa ntchito madzi, dongosololi liri mu tulo ndipo limadzuka pokhapokha pakufunika madzi;

(5) Kusintha kwa intaneti kwa magawo a PID;

(6) Kuwunika pa intaneti kwa liwiro lagalimoto ndi ma frequency

(7) Kuwunika kwenikweni kwa nthawi yolankhulana kwa wolamulira ndi PLC;

(8) Kuwunika kwenikweni kwa magawo a alamu monga overcurrent and overvoltage of controller;

(9) Kuwunika kwanthawi yeniyeni kwa seti ya pampu ndi alamu yodzitchinjiriza pamzere, kuwonetsa chizindikiro, ndi zina.

Chachinayi, ubwino luso la switched kunyinyirika zonse kuthamanga madzi dongosolo kotunga

Poyerekeza ndi njira zina zoperekera madzi nthawi zonse (monga kusinthasintha kwanthawi zonse), njira yosinthira kupanikizika kosalekeza kwamadzi imakhala ndi zabwino izi:

(1) Zofunika kwambiri zopulumutsa mphamvu. Iwo akhoza kukwaniritsa chaka chonse mabuku mphamvu kupulumutsa mlingo wa 10% -60%.

(2) Galimoto yosinthika yosinthika imakhala ndi torque yoyambira komanso yotsika poyambira. Itha kuyamba ndi nthawi 1.5 kuchuluka kwa torque pa 30% yapano. Ndi chiyambi chofewa chenicheni. Galimoto imathamanga momasuka molingana ndi nthawi yothamangitsira, kupeŵa zomwe zikuchitika pamene galimoto iyamba, kupeŵa kusinthasintha kwa magetsi a gridi yamagetsi, ndikupewa kuthamanga kwa makina opopera chifukwa cha kuthamanga kwadzidzidzi kwa galimotoyo. Chotsani chodabwitsa cha nyundo yamadzi.

(3) Itha kupangitsa kuti kusinthana kwa liwiro lagalimoto kuchuluke, ndipo magwiridwe antchito onse ndi apamwamba pamayendedwe onse othamanga. Ili ndi mawonekedwe abwino kwambiri otulutsa monga torque m'dera lapakati komanso lotsika pansi pa liwiro lovotera komanso kupitilira makumi kapena mazana osintha. Ikhoza kusintha liwiro la mpope ndi liwiro lalikulu, kupanga mpope kukhala chipangizo chanzeru. Ikhoza kusintha momasuka kutulutsa kwa mpope, kuchepetsa kukana kwa mapaipi ndikuchepetsa kutayika. Kuchita bwino kumawonekera kwambiri.

(4) Pampu imatha kusinthidwa momasuka. Pamene kutuluka kwatuluka kumakhala kochepa kusiyana ndi momwe amayendera, kuthamanga kwa mpope kumachepetsedwa, kuvala ndi kutentha kumachepetsedwa, ndipo moyo wautumiki wamakina wa mpope ndi galimoto umatalika.

(5) Kuwongolera kupanikizika kosalekeza, kuchotsa zida zina zowongolera, ndikupereka intaneti ya Zinthu ndi ma intaneti kuti zithandizire kuzindikira kwanzeru zadongosolo lonse. Dongosololi silifuna kugwira ntchito pafupipafupi ndi ogwira ntchito, zomwe zimachepetsa kwambiri kuchuluka kwa ogwira ntchito ndikupulumutsa antchito.

(6) Kudalirika ndi moyo wautumiki wamakina osinthika osinthika amagalimoto ndi apamwamba. Kuwunika ndi kukonza kwatsiku ndi tsiku kumachitika monga momwe zimafunikira, ndipo dongosolo lonse limatha kuyenda mosalekeza popanda kulephera kwa nthawi yayitali.

Ziwerengero ziwiri zotsatirazi zikuwonetsa mawonekedwe opitilira muyeso komanso mawonekedwe opitilira apo amakokedwe apamwamba a makina osinthika osunthika mumayendedwe othamanga kwambiri.

Ma motors osafuna kusintha amatha kuchepetsa kugwiritsa ntchito mphamvu ndi 60% chaka chilichonse populumutsa mphamvu zamakina omanga (HVAC).

5.1 Kuwunika nthawi yeniyeni

System main mawonekedwe

Mawonekedwe ogwirira ntchito a gawo lililonse la injini yosinthira, chowongolerera chosinthira chosinthika, PLC ndi sensor yokakamiza zimawonetsedwa pogwiritsa ntchito zithunzi ndi zolemba.

Mawonekedwe akulu amawonetsa kuthamanga kwagalimoto komweko, ma frequency ogwirira ntchito, kukakamiza, PID ndi magawo ena munthawi yeniyeni. Galimoto imangosintha liwiro molingana ndi kuchuluka kwa nthawi yeniyeni, kapena imatha kusinthidwa pamanja ndi wolandirayo. Pamene wolamulira kapena galimoto ikugwira ntchito molakwika, malo omwewo amawonekera tsiku la alamu ndi kufotokozera zolakwika.

Sikisi, nthawi zonse kuthamanga madzi ntchito malo ntchito

1. Madzi apampopi, nyumba zogona komanso njira zopangira madzi zozimitsa moto zingagwiritsidwenso ntchito popereka madzi otentha, kupopera mbewu mankhwalawa nthawi zonse ndi machitidwe ena.

2. Kupanga mabizinesi amakampani, makina operekera madzi am'nyumba ndi magawo ena omwe amafunikira kuwongolera nthawi zonse (monga kuthamanga kwa mpweya wokhazikika komanso kutulutsa mpweya wokhazikika wa air compressor system). Kuthamanga kosalekeza, kuwongolera kusinthasintha kwamphamvu, madzi ozizira komanso makina ozungulira operekera madzi munthawi zosiyanasiyana.

3. Malo opopera zimbudzi, kuyeretsa zimbudzi ndi njira yonyamulira zimbudzi.

4. ulimi wothirira ndi kupopera mbewu mankhwalawa m'munda.

5. Njira zoperekera madzi ndi zozimitsa moto m'mahotela ndi nyumba zazikulu za anthu.

7. Mwachidule

Anasintha kukana nthawi zonse kuthamanga madzi dongosolo kotunga ali ndi ubwino wa mphamvu zambiri kupulumutsa, odalirika ndi wanzeru kwambiri. Pakali pano, ndi mochulukira ambiri ntchito, osati angagwiritsidwe ntchito HVAC masukulu, zipatala, malo okhala, komanso nthawi zonse kuthamanga madzi kapena jekeseni madzi chofunika ndi mabizinesi osiyanasiyana mafakitale, monga kuzirala kufalitsidwa madzi, jekeseni wamadzi nthawi zonse m'minda yamafuta, etc. Njira yosinthira kupanikizika kwamadzi nthawi zonse sikumangopulumutsa magetsi ndi madzi, komanso imathandizira kwambiri magwiridwe antchito a dongosolo ndikutalikitsa moyo wautumiki. Ndi dongosolo lomwe limaphatikiza phindu lazachuma ndi luso laukadaulo, ndipo lili ndi chiyembekezo chogwiritsa ntchito.

1. Makina omanga (HVAC) opulumutsa mphamvu

Kutentha kwanyumba, mpweya wabwino ndi mpweya (HVAC) ndi gawo lofunikira pakugwiritsa ntchito magetsi. Komabe, kugwiritsa ntchito njira zamakono zopulumutsira mphamvu m'munda uno m'dziko langa ndizochepa, kotero pali kuthekera kwakukulu kowonjezera mphamvu zopulumutsa mphamvu. 70% ya mphamvu yamagetsi mu gawoli imadyedwa ndi mota, kotero kuti m'malo mwa mota ndikupulumutsa mphamvu zambiri ndi njira yolunjika.
