Zazzabi canji: makirci, da manufa na aiki, ganawa

Kariya na lantarki da kayan aiki daga wuce haddi da kaya thermal gudun ba da sanda na samar da. Ba tare da shi, da wayoyi don overheat, sakamakon bai kai ba gazawar da rufi.

manufa na aiki

thermal gudun ba da sanda aiki ne don cire haɗi a kewaye a lokacin da na yanzu suna gudãna ta hanyar shi ya wuce maras muhimmanci. The inji kunshi termopodogrevatelya ta hanyar abin da lantarki ya wuce, da kuma wani farantin daga cikin bimetal, wanda ya nàkasasshē kan dumama, kuma ya bude Lambobin sarkar. A mafi girma da na yanzu, da sauri da aiki.

Bayan da bude kewaye thermocouple cools da kuma ya koma ga asalin jihar.

Iri makircinsu na fuser

Thermal gudun ba da sanda aiki ta hanyar biyu makircinsu:

• sharuddan sauyawa lambobi suna rufe da baya da karfi;
• makirci da aka sake saita kansa.

A farko embodiment da dangantaka da thermal m gudun ba da sanda (electromagnetic contactors, kewaye hutu et al.). A na biyu da aka yi amfani da zazzabi kayyade abubuwa tsarin (a firiji, wani baƙin ƙarfe, mai tsanani kasa et al.).

A bimetallic farantin a deflection abubuwa a kan lamba kungiyoyin, wanda ya buɗe lantarki kewaye. Saboda low martani gudun da na'urar ba bice baka da ake so sakamako. A yau gudun ba da sanda na'urorin da ake amfani da shi, da kara bude kewaye gudun.

Iri thermal zango

Thermal zango da aka zaba a maras motor kaya wucewa da shi ta hanyar 20-30%. Tare da irin wannan obalodi tuntube ya auku bayan 20 min. A bimetallic farantin sags sannu a hankali. A wannan batun, shi abubuwa a kan fil ta hanyar da accelerating na'urar (lamba bouncing). Wadannan iri thermal gudun ba da sanda.

1. RTP - kare uku lokaci Motors da thermoelements a kan igiyoyin up zuwa 600 A kuma wani DC ƙarfin lantarki networks har zuwa 150 A. The bimetal farantin an mai tsanani da hita, kuma a halin yanzu suna gudãna therethrough. actuating halin yanzu an da hannu gyara ta hanyar da farko nakasawa daga cikin farantin. Sake saita ta latsa maballin, amma akwai wani version tare da kai-resetting.
2. RTL - domin kariya daga uku lokaci shigar da Motors da shafe tsawon obalodi, lokaci unbalance yayin da na'ura mai juyi jamming, ko a mai tsanani farko. A irin wannan yanayi, aiki da lantarki dagawa sunadaran, farashinsa, magoya, da kuma sauran inji. Relay saka a cikin Starter, da kuma sa mutum na'urorin.
3. PTT - kunshe a cikin kaya na kariya na uku lokaci shigar da Motors da shafe tsawon obalodi, lokaci unbalance, da dai sauransu su iya saka a cikin .. Magnetic actuators a AC da kuma DC haihuwarka.

Control da kuma sanyi

A electrothermal zango ya zama lokaci-lokaci sa da-kori-kura darajar. Farko da dubawa da kuma tabbatar da qaddara ne na cikin gida da yawan zafin jiki. Lokacin da auna da yanayin da lambobi, bimetal faranti, fastening abubuwa da sunadaran.

Girkawar ga kadan daidaitacce thermostat sa zuwa ga kara ko ragewa, inda kowane rabo daga cikin sikelin yayi dace da kyautatuwa 10 ° C. Idan zango da zazzabi diyya, babu gyara ake bukata.

Gyara da aka yi ta yi aiki a wata shida-Musulunci karuwa a ina _nom. Tare da low inertia na'urorin aka kunna a cikin tazara na 0.5-4 s, da kuma tare da babban - daga 4 zuwa 25 seconds. Sa'an nan kuma, ta yin na yanzu ƙaruwa daga 1.2 zuwa na _nom. Zango da haka ya kamata cire haɗin lambobi 20 min.

sauki thermostats

Zazzabi canji za a iya halitta dangane da lantarki da ake amfani da su kula da qaddara da zazzabi yanayin da kwamfuta, gabatarwa, incubator da t. D. Don wannan thermostat za a iya amfani, da kewaye daga wanda qunshi wani haska kunshi aunawa da kuma tunani poluplecha thermistor R ₂ da kuma resistors R _1, R _3, R _4.

Lokacin da zazzabi canje-canje dabam da juriya darajar R _2. The kuskure siginar da aka ciyar da daga gada zuwa shigar da LM393 IC. Yana aiki a cikin comparator yanayin inda mashiga 3 na analog sigina ne ba zato miƙa mulki daga ta kashe jihar ta aiki. Signal daga fitarwa kewaye da aka Littafi da transistor Q _1, sa'an nan da fan triggering faruwa. Yana cools da thermistor, sa'an nan da comparator sauya kashe da fan. A wannan hanya, thermal management auku via iska sanyaya.

Na'urar haska bayanai ga zazzabi iko da kasa dumama

A irin wannan manufa domin gudanar da tsarin na kasa dumama.

The AC ƙarfin lantarki 230 amfani da shigar da na'urar sa'an nan tuba a wani transformerless samar da wutar lantarki zuwa akai 15 W. A kan dokin aka bayyana divider R _{4, 5 R,} R _9. Lokacin da sanyi bene, R ₉ thermistor juriya ne 10 ohms. A TL431 zener sami wani alama a sama 2.5 volts sarkar VD _3, R _6, HL _2, U _1. Nuni da wannan ne yake aikata diode HL _2. Triac VS ₁ da aka kunna kuma irin ƙarfin lantarki kawota zuwa bene dumama. Lokacin da ta zazzabi ya kai wani qaddara darajar, da thermistor juriya R ₉ (haska) an rage don haka da cewa Zener diode a lura da shigar da alama darajar zama kasa da 2.5 V. TL431 kulle, kuma a gare su su optosimistor triac. A sakamakon haka, da hita naúrar yana kashe. Da zaran bene fara kwantar, da tsari da aka maimaita.

A m da kuma matsakaicin yawan zafin jiki da aka kafa ta resistors R ₄ da R _5. Sauya sheka dokin da aka gyara bayan shigarwa na haska R _9. Its located a tsakiyar tsakanin hita coils. Da ikon fitarwa, sarrafa ta a thermal gudun ba da sanda, shi ne dogara a kan darajar da juriya R _7.

Upcoming haska tashoshi rufe shrinkable tube, da kuma shãfe haske da na USB taye ko m Layer. Karshe shi ne bu mai kyau a saka a cikin wani tagulla hannun riga da cika tare da epoxy guduro. Top rufi kasa tiles.

How to connect da thermostat da hita, za a iya gani a cikin zane, wanda aka wakilta a jiki na da yawa model. Yana kuma iya iya samu a cikin bayanin da na'urar.

Industrial thermostat ga hita za a iya zaba daga cikin wadannan iri:

• electromechanical - tare da manual sake saiti canji.
• dijital - iko aka yi azanci shine ko tactile mashiga, da kuma dole bayanai (na yanzu zafin jiki da kuma saituna) an nuna a kan nuni.
• programmable - hita saitin na shirin na qayyadedden lokaci, da kuma mugun sarrafawa da kwamfuta.

ƙarshe

Akwai hanyoyi da dama da yadda za a gama a thermal gudun ba da sanda ga na'urorin. A baya can, suka yi don tattara da hannuwansu. Yanzu a kasuwa, za ka iya zabar da thermostat, wanda makirci ne optimally kamar da hita (lantarki boilers, dumi kasa da sauransu.). Yana da muhimmanci a samar da zama dole aiki, AMINCI da aminci a aiki.
