Kuyambitsa kutentha ndi chinyezi chowongolera

Mwachidule

Chiwongolero cha kutentha ndi chinyezi chimakhazikitsidwa ndi makina ang'onoang'ono ang'onoang'ono monga makina olamulira, ndipo amatengera kutentha kwapamwamba ndi kutentha kwa chinyezi, zomwe zimatha kuyeza ndi kulamulira kutentha ndi chinyezi nthawi imodzi, ndikuzindikira kuwonetsera kwa digito kwamadzimadzi. .Malire apansi amaikidwa ndikuwonetsedwa, kotero kuti chidacho chikhoza kuyambitsa fani kapena chowotchera molingana ndi malo omwe ali pamalopo, ndikusintha kutentha kwenikweni ndi chinyezi cha chilengedwe choyezedwa.

Working mfundo

Wowongolera kutentha ndi chinyezi amapangidwa makamaka ndi magawo atatu: sensor, controller ndi heater.Mfundo yake yogwirira ntchito ndi motere: sensa imazindikira kutentha ndi chinyezi m'bokosi, ndikutumiza kwa wolamulira kuti afufuze ndi kukonza: pamene kutentha ndi chinyezi mu bokosi zikufika kapena Pamene mtengo wokonzedweratu wadutsa, kukhudzana ndi relay. mu chowongolera chatsekedwa, chowotcha chimayendetsedwa ndikuyamba kugwira ntchito, kutentha kapena kuwomba mpweya mubokosi;Patapita nthawi, kutentha kapena chinyezi m'bokosi ndi kutali ndi mtengo woikidwiratu, ndi The relay kulankhula mu chipangizo otsegula, Kutentha kapena kuwomba amasiya.

Akupempha

Kutentha ndi chinyezi Mtsogoleri mankhwala zimagwiritsa ntchito kusintha ndi kulamulira kutentha kwa mkati ndi chinyezi cha sing'anga ndi mkulu voteji makabati lophimba, mabokosi terminal, makabati mphete maukonde, thiransifoma bokosi ndi zipangizo zina.Itha kuteteza bwino kulephera kwa zida zomwe zimayambitsidwa ndi kutentha kochepa komanso kutentha kwambiri, komanso ngozi za creepage ndi flashover zomwe zimachitika chifukwa cha chinyezi kapena condensation.

Gulu

Owongolera kutentha ndi chinyezi amagawidwa m'mitundu iwiri: mndandanda wamba ndi mndandanda wanzeru.

Kutentha wamba ndi chinyezi chowongolera: Zimapangidwa ndi kutentha kwa polima ndi sensa ya chinyezi, kuphatikizidwa ndi mayendedwe okhazikika a analogi ndi ukadaulo wosinthira magetsi.

Kutentha kwanzeru ndi chinyezi chowongolera: Imawonetsa kutentha ndi chinyezi monga machubu a digito, ndipo imakhala ndi chotenthetsera, chowonetsa cholakwika cha sensor, ndi ntchito zotumizira.Chidacho chimagwirizanitsa kuyeza, kuwonetsera, kulamulira ndi kulankhulana.Ili ndi miyeso yolondola kwambiri komanso yotakata.Chida choyezera kutentha ndi chinyezi ndi chida chowongolera choyenera kumafakitale ndi magawo osiyanasiyana.

Kalozera wosankha

Wolamulira wanzeru wa kutentha ndi chinyezi amatha kuyeza pazigawo zingapo nthawi imodzi, ndikuwongolera kutentha ndi chinyezi cha chilengedwe pazigawo zingapo.Mfundo zotsatirazi ziyenera kuphatikizidwa poyitanitsa: chitsanzo cha mankhwala, magetsi othandizira, magawo olamulira, kutalika kwa chingwe, chowotcha.

Mkukonzekera

Kusamalira kutentha ndi chinyezi chowongolera:

1. Nthawi zonse yang'anani momwe ntchito ya wolamulira akuyendera.

2. Onani ngati ntchito ya firiji ndi yabwinobwino (ngati fluoride ili yochepa, fluoride iyenera kuwonjezeredwa panthawi yake).

3. Onani ngati madzi apampopi akukwanira.Ngati madzi kulibe, zimitsani chosinthira cha chinyezi munthawi yake kuti musawotche chinyontho.

4. Yang'anani zingwe ndi zotenthetsera ngati zatha.

5. Yang'anani ngati mutu wopopera watsekedwa.

6. Zindikirani kuti pampu yamadzi ya humidification idzasiya kuzungulira chifukwa cha matope a madzi omwe sagwiritsidwa ntchito kwa nthawi yaitali, ndikutembenuzira tsamba la fan pa doko loyendetsa kuti likhale lozungulira.

Zinthu zofunika kuziganizira

1. "Kuyendera tsiku ndi tsiku" mwezi uliwonse kuyenera kuyang'ana kukhulupirika kwa chowongolera kutentha ndi chinyezi, ndikufotokozera vutolo panthawi yake kuti likhale labwino.Mtunda pakati pa chitoliro cha kutentha ndi chingwe ndi waya si osachepera 2cm;

2. Zowongolera kutentha ndi chinyezi za mabokosi onse a terminal ndi mabokosi amakina ziyenera kuyikidwa pamalo olowetsamo, kuti kutentha ndi chinyezi ziwongoleredwe munjira yoyenera.

3. Popeza kuwonetsera kwa digito kutentha ndi wowongolera chinyezi alibe ntchito yokumbukira, nthawi iliyonse mphamvu ikatsekedwa, zoikidwiratu za fakitale zidzabwezeretsedwanso mphamvu ikayatsidwanso, ndipo zoikidwiratu ziyenera kukonzedwanso.

4. Pewani kugwiritsa ntchito chowongolera kutentha ndi chinyezi m'malo okhala ndi fumbi lambiri.Yesani kukhazikitsa makina pamalo otseguka.Ngati chipinda choyezedwa ndi makina ndi chachikulu, onjezerani chiwerengero cha kutentha ndi chinyezi.

Troubleshooting

Zolakwitsa zodziwika bwino za zowongolera kutentha zanzeru:

1. Pambuyo pa kutentha kwa nthawi, kutentha sikumasintha.Nthawi zonse onetsani kutentha kwapamalo (monga kutentha kwa chipinda 25°C)

Mukakumana ndi vuto loterolo, choyamba fufuzani ngati mtengo wa SV mtengo wakhazikitsidwa, ngati kuwala kwa OUT kwa mita kuli pamoto, ndipo gwiritsani ntchito "multimeter" kuti muwone ngati 3rd ndi 4th terminals ya mita ili ndi 12VDC yotuluka.Ngati kuwala kwayaka, ma terminals 3 ndi 4 alinso ndi 12VDC yotulutsa.Zikutanthauza kuti vuto lagona mu chipangizo chowongolera cha kutentha kwa thupi (monga AC contactor, solid state relay, relay, etc.), fufuzani ngati chipangizo chowongolera chili ndi dera lotseguka komanso ngati mawonekedwe a chipangizocho ndi olakwika (monga Chipangizo cha 380V mu dera la 220), Kaya mzerewo umagwirizanitsidwa molakwika, ndi zina zotero, fufuzani ngati sensa imakhala yochepa (pamene thermocouple imakhala yochepa, mita nthawi zonse imasonyeza kutentha kwa chipinda).

2. Pambuyo pa kutentha kwa nthawi, kutentha kumatsika ndikutsika

Mukakumana ndi vuto lotere, ma polarities abwino ndi oyipa a sensor nthawi zambiri amasinthidwa.Panthawiyi, muyenera kuyang'ana mawaya olowera kumtunda wa sensa ya chida (thermocouple: 8 ikugwirizana ndi mtengo wabwino, ndipo 9 ikugwirizana ndi mtengo woipa; PT100 kukana kutentha: ?8 ikugwirizana ndi waya wamtundu umodzi, 9 ndi 10 amalumikizidwa ndi mawaya awiri amtundu womwewo).

3. Pambuyo pa kutentha kwa nthawi, mtengo wa kutentha (PV mtengo) woyezedwa ndi kuwonetsedwa ndi mita ndi wosiyana kwambiri ndi kutentha kwenikweni kwa chinthu chotenthetsera (mwachitsanzo, kutentha kwenikweni kwa kutentha ndi 200 ° C; pomwe mita ikuwonetsa 230°C kapena 180°C)

Mukakumana ndi vuto lotere, fufuzani kaye ngati malo olumikizirana pakati pa kutentha kwa kutentha ndi thupi lotenthetsera ndi lotayirira komanso kusalumikizana kwina, ngati kusankha kwa malo oyezera kutentha ndikolondola, komanso ngati mawonekedwe a sensor ya kutentha akugwirizana ndi kuyika kwa chowongolera kutentha (monga mita yowongolera kutentha).Ndi mtundu wa K-thermocouple wolowetsa, ndipo thermocouple yamtundu wa J imayikidwa pamalopo kuti ayeze kutentha).

4. Zenera la PV la chidacho limawonetsa zilembo za HHH kapena LLL.

Cholakwa choterocho chikapezeka, zikutanthauza kuti chizindikiro choyezedwa ndi chipangizocho ndi chosazolowereka (LLL ikuwonetsedwa pamene kutentha komwe kumayesedwa ndi chipangizocho kuli kotsika kuposa -19 ° C, ndipo HHH ikuwonetsedwa kutentha kwapamwamba kuposa 849 ° C. ).

Yankho: Ngati sensa ya kutentha ndi thermocouple, mutha kuchotsa sensa ndi kufupikitsa ma terminals a thermocouple (materminal 8 ndi 9) a chidacho ndi mawaya.℃), vuto liri mu sensa ya kutentha, gwiritsani ntchito chida cha multimeter kuti muwone ngati sensa ya kutentha (thermocouple kapena PT100 kutentha kukana) ili ndi dera lotseguka (waya wosweka), kaya waya wa sensayo walumikizidwa molakwika kapena molakwika, kapena sensor. mafotokozedwe amatsutsana ndi chida.

Ngati mavuto omwe ali pamwambawa achotsedwa, dera loyezera kutentha kwa mkati mwa chipangizocho likhoza kuwotchedwa chifukwa cha kutuluka kwa sensa.

5. Kuwongolera sikungatheke, kutentha kumaposa mtengo wokhazikitsidwa, ndipo kutentha kwakhala kukwera.

Mukakumana ndi vuto loterolo, fufuzani kaye ngati chowunikira cha OUT cha mita chilipo panthawiyi, ndipo gwiritsani ntchito magetsi a DC a "multimeter" kuti muwone ngati 3rd ndi 4th terminals ya mita ili ndi 12VDC yotuluka.Ngati kuwala kwazimitsidwa, ma terminals 3 ndi 4 alibe 12VDC yotulutsanso.Zimasonyeza kuti vuto lagona mu ulamuliro chipangizo cha Kutentha chinthu (monga; AC contactor, olimba boma kuponyerana, kulandirana, etc.).

Yankho: Yang'anani chipangizo chowongolera nthawi yomweyo kuti chikhale chozungulira, chosasweka, kulumikizana kolakwika, ndi zina.
