Hoʻoponopono o ke ana wela loli ma luna o ka maʻi hiki ke i lolouila ka manaʻo, a maoli he i ka pololei o ke ana.

He aha ke ia ke thermocouple. Price a me ka hiʻona

A thermocouple hiki ke welded kekahi mau kaula o dissimilar ke hooheheeia. E hoʻohana interchangeably i loko o ka hana pono hiki ke withstanding kiʻekiʻe mahana, mau nō, a me ka kiʻekiʻe thermo-electromotive ikaika. Aia nō i nā kūpaʻa manao maalea me kiʻekiʻe miomio, a me ka ia pae'ōnaehana rula, akā, thermocouple simpler a ho'ēmi i hoʻomākaukauʻia.

ʻO nā uila aʻa lolo hoʻohana palupalu annealed uea o kūikawā oka a pau. Ua hana ma ka i kā mākou mahana o ma kahi o 1000 degere. Na oka a pau i ka pilina paʻa, a kiʻekiʻe thermo-electromotive ikaika nā loina.

nā mea e loaʻa ka mea nalo a me nā nā uila aʻa lolo, a pau ka cathode mea he nikala-chromium oka a (Chromel) ka loa, he pono ole, a me ka anode - kekahi mea hiki ke hooheheeia, e like me alumel (thermocouple TCA). Ke simplest pili ua i ia me ka ke'ō.

Kēlā me kēiaʻano o ka mīkiniʻimi i kekahi i loko o ka hana ana wela huahelu, huina o ua loaʻa emf, ia'ku i ÿole mechanical, a Nine Inch kaua, mea paʻa a me ka interchangeability.

He mea e pono ai wale nō e kūʻai ia mau manaʻo, a hoʻopili like i ke koi 'ia kiko'î. Ua pili hoi i ka wela ia'ku, a e koke ana i ka hoʻololi 'ana i ke kūlana kiʻekiʻe.

Thermocouple no ka eioaeuiie i loko o Oko ke kaumaha ma muli o ka hoohalike. e kokua holo 'awelika i ka hola ma ka ia pae. Ma awelika, e hoike no 500-600 rubles. I kuai ma laila mau nō hoʻi nā mea e loaʻa ka mea nalo piha me nā lolouila mīkini hoʻololi, aʻo ka uku mea kaniʻikepili. He ua noniakahi 'ana i loko o ka thermocouple poo. Mīkiniʻimi kumukuai mea kiekie, akā, ka mea 'aʻole i koi uku' kaula. K thermocouple poo hiki e pili ana iʻike mau keleawe uea.

Kaʻoi loa lawe i nā huahana no kekahi Ke Ana Hoʻohālike, hoakaka no i kupono pu. Universal lima kūlana kiʻekiʻe mea paʻa e ole oko.

'ano o nā mea e loaʻa ka mea nalo

1. E kikokiko K nikala-chromium (TXA thermocouple) a nikala-alumel (HA) me na kēia mau waiwai: haʻahaʻa waiwai e lilo aku, mea paʻa, pololei mea i oi aku mamua o 0,4%, ana huahelu mai -270 a hiki i 1269 degere. Papahana no ka hana i loko o ka oxidizing a me ka inert me ka lewa.

2. L - chromel-kopel (TCA), inexpensive thermocouple me kekahi keena kali o ka 600 degere.

3. J - hao-constantan. Mīkiniʻimi hookūlana lua ma ka hiʻona, ka laulā mea mai -210 a hiki i 760 degere, emi mau nō, hoʻopale i ka'okesaside.

4. E - he nikala-chromium a nikala-constantan me kiekie ae pololei a me ka neaiae waiwai, ka luna palena o ke ana, aole ia i oi aku mamua o 870 degere.

5. Nā mea e loaʻa ka mea nalo i ka mea maikai i eliiaʻi hana ma ka wela kiʻekiʻe, akā, i ke kiʻekiʻe lilo, a no ia mea, i ka hapanui mau hoʻohana 'ia ma ka hana.

Nā kinolau thermocouple e pili ana

Ma ka ana epekema loa, he pono ole ili nā mea e loaʻa ka mea nalo. Ka mea, uea welau i welded i loko o ka hookahi pa alima,ʻAha ma ke kupaianahaʻimi. Ka lole o ka hui 'ana me ka aiiay mawaho iwi, a ma ka wela ua hoolilo koke, a me ka thermocouple mea haʻahaʻa' oni '. I ka pololei o kaʻikepili ua nui loli ana ma uila 'ākeʻakeʻa. E like me ka hiki i keia rula hana thermocouple no ke kinoea ieoaeunoai. Ke ana mea pela e ole e ili like ma ka honua ke i nā wahi i puhi ai, a alakaʻi mai i loko o kaʻikepili hewa.

Inā ka huina mea,ʻaʻole ma ka hui 'ana me ka aiiay iwi, laila, ua kapaʻia kēia manao ili. I loko nō o ka mea i loko o keia hihia i ka mämä holo mīkiniʻimi emi, ia mea emi susceptible e hoʻoʻauwana uila 'ākeʻakeʻa.

Hana huina hiki no hoi ke 'ana i loko o ke kaʻina hana, akā, i kēia iaoia ho'ēmi i kā ka hana ke ola o ka mea aie i ka popopo. Ma ka? Iecaianoaaiiie o ia ka thermocouple ua hoʻohana 'kākaʻikahi, a me ko ka hale ona nā mīkini home e ike hiki mai'ō a'ō.

No ka ana i ka mahana i loko o kekahi mau kumu noi multizone thermocouple. pili noaia ia mea ma luna o ka ia rula, wale i ka mea pili i ka kekahi nā mea e loaʻa ka mea nalo ke aupuni 'o elua a oi mau wahi.

Pehea e holo ai i ka thermocouple me ke kinoea ieoaeunoai

Thermocouple - He aha ka mea? No ka mea hoʻohana, nā mea a pau i ike, i ka wa e haule ana na ka hoʻohuikau 'o ke kinoea lako a pan. Hana thermocouple hookui i loko o ka ieoaeunoai ua enaena, ma ka ke kahu moku, lapalapa ahi. Ke kaapuni Uaʻonou thermal emf like ia 20-25 MV, a waiwai, ua lawa no ka hana i ka solenoid kiwikā. Ua weheʻia ke kinoea lako i ka paio hahana maoli nō ieoaeunoai. Mea hō'ā kaʻa puhiʻino mau hana ana o ka ieoaeunoai hana. Mai kona papa kuhikuhiE puhiʻino ua ignited, he hahana maoli nō kēia wai. Ke thermocouple no ka kinoea cookers i pono, e hoomakaukau no ka pila mea hō'ā kaʻa burners.

Eia kekahi, nae kekahi una honua me ka hoomalu i ka hihia o ka hoʻolako 'ole i loko o ke kokuaia mai e ka wā i ke kinoea ua lilo ma ka mea ulana pukapuka, a laila hakahaka hou.

I'ā kinoea lapalapa i loko o ka ieoaeunoai makahiki adhesions thermoelectrodes ia mea pii kai iki ana, a pela i ka wahie haawi. Ma hope o ka lapalapa ua pio, i ka thermocouple wela huina anuanu, a ia pohaku e lawaʻikena. A pau keia ua ua hō'ā aku solenoid kiwikā, kinoea ua paniʻia.

Check o serviceability

Thermocouple no ke kinoea ieoaeunoai kulana kupono ma ke solenoid kiwikā, i ua kuaiia ma ka hana kūikawā papa kāwiliʻai. Ma ka hopena o ka o Kahualoa Kokohi kiwikā E e soldered mau'ōlewa kaula me clamps "crocodile", a laila, hoʻohui i nā maʻi o ka thermocouple. I ka wela, ka wela hookui o ka thermocouple kōna i loko o ka lapalapa o ke kinoea puhiʻino paha suppositories kiwikā e hana mai ka mea ua loaʻaʻikena. Ka mea ka loa a me ka oluolu unpretentious.

O kéu hoʻomaopopo i ka ka hoʻokōʻana o ka thermocouple ua i hua mai la i ka hoʻohana 'ana millivoltmeter. Ke anakahi uila ma kona noa welau, e e emi malalo o 25 MV.

Kekahi kumu no ka shutdown o ka hewa ke kahu moku thermocouple. Ilihune hana hiki e kena ae la ma ke kahua o ka haole huahelu ma kahi o na spike in. Kona hoʻomaikaʻi i sandpaper "nulevkoy". Wale Pono e wehe plaque. I ole ia, e lukuia auanei lakou e spike in.

I anaʻe o ka thermocouple kaula hiki e pili ana ma kekahi pōkole apana o kaʻike mau keleawe uea. He nui e waiho i ka hui 'ana i loko o ka hookahi ana wela.

Inā thermocouple puhi ieoaeunoai, ka mea pono e auou caiaiai. He hiki ke kaula hō'ā i ka palena o na kaula ma ka kihi loa ia laua, a hoʻohui i nā maʻi o ka pu ki. Pela ka mea, Ua pono, e koho i ka manawa pono e hoʻohui, e kiʻi i kekahi mea e like ai SPIKE. Eia hou kekahi, ia mea pono e hana ai i loko o ka thermocouple kaula i ku ole i ka mea hiki ke hooheheeia o na pu ki maʻi. Place kihi loa o ka kuʻihao kaʻina ua ana bapetizo i loko o ka graphite ka pauka. Inā e ohi i Latro ka manaʻo, e hiki hoʻomaʻa i ka pono, a me ka ami makemake mea e like ai. A pau o kēia mau ana i? Aiaiiuie, i ka mea kūpono, kinoea thermocouple e auou caiaiai ma ka hou kekahi.

ka hopena

Thermocouple - He aha ka mea? He He mea thermoelectric mīkini hoʻololi. Pono a me ka mea paʻa o ka mea e ka mea i paʻa mau paahana no ke kinoea ieoaeunoai aku ma ka hihia o ka pilikia.

no hoi Thermocouples mea hoʻohana no ka uila mea hō'ā kaʻa ma ka kinoea stoves, a me ka mahana nā mea e loaʻa ka mea nalo.
