I-Thermocouples yenye yezona ntlobo zixhaphakileyo zokuvavanya ubushushu kwihlabathi jikelele. Ziyaziwayo kwiinkalo ezahlukeneyo ngenxa yoqoqosho lwabo, ukuqina kunye nokuguquguquka. Ukusetyenziswa kwe-thermocouple ukusuka kwi-ceramics, igesi, i-oyile, isinyithi, iglasi kunye neeplastiki ukuya kukutya kunye neziselo.
Ungazisebenzisa naphi na ukujonga ngokuchanekileyo okanye ukurekhoda idatha yobushushu. IiThermocouples ziyaziwa ngokuvelisa imilinganiselo yobushushu ngokuphendula ngokukhawuleza kunye nokumelana okugqwesileyo ukothuka, ukungcangcazela kunye namaqondo obushushu aphezulu.
I-thermocouple yinzwa esetyenziselwa ukulinganisa ubushushu kwisayensi, ukuvelisa, kunye nokusetyenziswa kweteknoloji. Yenziwa ngokudibanisa iingcingo ezimbini zentsimbi ezingafaniyo kunye ukuze zenze isiphambuka. Isiphambuka sidala amandla ombane aqikelelweyo kuluhlu olunikiweyo lobushushu. I-Thermocouples ngokuqhelekileyo isebenzisa i-Seebeck okanye i-thermoelectric effect ukuguqula i-voltage ibe ngumlinganiselo wobushushu.
I-Thermocouples inezicelo ezininzi kwishishini lokutya kunye nesiselo elifana ne-pasteurization, ifriji, i-fermentation, ukutywala kunye nokufaka iibhotile. Awunaxhala xa usebenzisa igeyiji yobushushu be-thermocouple njengoko ibonelela ngokuqhotsa okuchanekileyo kunye nokufundwa kobushushu bokupheka ukuze uqiniseke ukuba ukutya kwakho kuphekiwe.
Ii-Thermocouples zihlala zisetyenziswa kwisixhobo sokutyela esinje ngegrill, iithosta, iifryi ezinzulu, izifudumezi, kunye nee-oveni. Ukongeza, unokufumana i-thermocouples ngendlela yeenzwa zobushushu kwizixhobo zasekhitshini ezisetyenziswa kwizityalo ezinkulu zokulungisa ukutya.
I-Thermocouples zikwasetyenziswa kwiindawo zokusela kuba imveliso yebhiya ifuna amaqondo obushushu achanekileyo ukuze ivundiswe ngokufanelekileyo kwaye ithintele ukungcoliseka kwe-microbial.
Umlinganiselo wobushushu ochanekileyo wesinyithi esinyibilikisiweyo njengentsimbi, i-zinc kunye ne-aluminiyam kunokuba nzima ngenxa yobushushu obuphezulu ngokugqithisileyo. Izinzwa zobushushu ezisetyenziswa ngokuqhelekileyo kwiintsimbi ezityhidiweyo ziyi-platinum thermocouples iindidi ze-B, S kunye ne-R kunye nesiseko se-thermocouples zetsimbi iintlobo ze-K kunye ne-N. Ukukhethwa kohlobo olufanelekileyo luya kuxhomekeka kwiqondo lokushisa lesicelo esithile esihambelana nesinyithi.
Isiseko se-thermocouples yensimbi ngokuqhelekileyo sisebenzisa i-US No. 8 okanye iNombolo ye-14 (AWG) igeyiji yocingo kunye netyhubhu yentsimbi kunye ne-ceramic insulator. Iplatinam thermocouples, kwelinye icala, iqhele ukusebenzisa #20 ukuya #30 AWG idayamitha.
Ukuveliswa kweemveliso zeplastiki kufuna ulawulo oluchanekileyo lobushushu. Ii-Thermocouples zihlala zifuneka kulawulo lobushushu kwiindawo ezahlukeneyo zokusetyenzwa kweeplastiki. Zisetyenziselwa ukulinganisa ukunyibilika okanye ubushushu bomhlaba kwizitofu zokubumba kunye nenaliti yokubumba.
Ngaphambi kokusebenzisa i-thermocouples kwi-processing yeplastiki, kufuneka wazi ukuba kukho iindidi ezimbini ze-thermocouples kwishishini leplastiki. Udidi lokuqala lubandakanya imilinganiselo. Apha, i-thermocouples ingasetyenziselwa ukumisela umsebenzi wokutshintshwa kobushushu beeplastiki ngokuxhomekeke kwicandelo labo lomnqamlezo. Khumbula ukuba i-thermocouple kufuneka ibone umehluko kumandla asetyenzisiweyo, ngokukodwa ngenxa yesantya kunye nolwalathiso.
Ungasebenzisa kwakhona i-thermocouples kuphuhliso lwemveliso kwishishini leplastiki. Ngaloo ndlela, uhlobo lwesibini lwesicelo se-thermocouples kwishishini leplastiki libandakanya ukuyila kwemveliso kunye nobunjineli. Kuphuhliso lwemveliso, kufuneka usebenzise i-thermocouples ukubala utshintsho lobushushu kwizinto eziphathekayo, ngakumbi kubomi bemveliso.
Iinjineli zinokukhetha ii-thermocouples ezifanelekileyo kwizinto ezizisebenzisayo ekwenzeni iimveliso zabo. Ngokufanayo, banokusebenzisa i-thermocouples ukuvavanya ukusebenza koyilo. Oku kuya kubavumela ukuba benze utshintsho phambi kokuba inkqubo yemveliso iqale.
Iimeko zesithando somlilo zichaza ubukhulu becala i-thermocouple efanelekileyo yesithando somlilo esiphezulu sebhubhoratri. Ke ngoko, ukukhetha eyona thermocouple ilungileyo, kufuneka kuqwalaselwe izinto ezininzi, ezinje:
Kwiimeko ezininzi, i-extruders ifuna uxinzelelo oluphezulu kunye nobushushu obuphezulu. I-Thermocouples ye-extruders ine-adapters enemisonto enceda ukubeka iingcebiso zabo zeprobe kwiplastiki etyhidiweyo, ngokuqhelekileyo phantsi koxinzelelo oluphezulu.
Unokwenza ezi thermocouples njengento enye okanye ephindwe kabini enezindlu ezinemisonto eyodwa. I-Bayonet thermocouples (BT) kunye ne-compression thermocouples (CF) zidla ngokusetyenziswa kumacandelo oxinzelelo oluphantsi lwe-extruder.
Iindidi ezahlukeneyo ze-thermocouples zinezicelo ezininzi kumashishini ahlukeneyo. Ke ukuba usebenza kubunjineli, intsimbi, ukutya kunye nesiselo, okanye ukusetyenzwa kweeplastiki, uya kufumanisa ukuba ii-thermocouples zisetyenziswa ngokubanzi kumlinganiselo wobushushu kunye nolawulo.
