Isishwankathelo seCandelo 1

Ii-thermocouples zeplatinum-iridium 10-platinum ezisemgangathweni zebanga lokuqala nelesibini ezineempawu ezilungileyo zomzimba nezekhemikhali, ukumelana okuhle kwe-oxidation kumaqondo obushushu aphezulu, uzinzo oluhle kunye nokuphindaphinda kwamandla e-thermoelectromotive. Ke ngoko, isetyenziswa njengesixhobo sokulinganisa esisemgangathweni kwi (419.527 ~ 1084.62) °C, ikwasetyenziselwa ukudlulisa ubungakanani bobushushu kunye nokulinganisa ubushushu ngokuchanekileyo kuluhlu lobushushu.

Inxalenye 3 Imiyalelo yesicelo

Iithermocouples zeplatinum-iridium 10-platinum ezisemgangathweni kufuneka zihambelane netheyibhile yenkqubo yokuhanjiswa kwesizwe, kufuneka kusetyenziswe iinkqubo zokuqinisekisa zesizwe. Iithermocouples zeplatinum-iridium 10-platinum ezisemgangathweni zodidi lokuqala zingasetyenziselwa ukulinganisa iithermocouples zeplatinum-iridium 10-platinum zebanga lesibini, ibakala le-Ⅰ, ibakala le-Ⅱ kunye neethermocouples zesinyithi ezisisiseko sebanga le-Ⅰ; Iithermocouples zeplatinum-iridium 10-platinum zebanga lesibini zingasetyenziselwa ukulinganisa iithermocouples zesinyithi ezisisiseko sebanga le-Ⅱ

Icandelo 4 Ukugcinwa nokugcinwa

1. Ixesha eliqhelekileyo lokulinganisa i-thermocouple ngunyaka omnye, kwaye rhoqo ngonyaka i-thermocouple eqhelekileyo kufuneka ilinganiswe lisebe le-metrology.

2. Uvavanyo olufunekayo lokujonga kufuneka lwenziwe ngokwendlela olusetyenziswa ngayo.

3. Indawo yokusebenza ye-thermocouple esemgangathweni kufuneka icoceke ukuze kuthintelwe ukungcoliswa kwe-thermocouple esemgangathweni.

4. I-thermocouple eqhelekileyo kufuneka ibekwe kwimeko engangcolisiyo kwaye ikhuselwe kuxinzelelo loomatshini.

Icandelo 5 Amanyathelo okhuseleko xa usebenzisa

1. Ityhubhu yokukhusela ayinakusetyenziswa xa kutshiswa ngobushushu obuphezulu. Ityhubhu yokukhusela yokuqala isetyenziswa emva kokucoca ngokungqongqo kunye nokutshiswa ngobushushu obuphezulu.

2. Ityhubhu yokukhusela ayizinaki izinto ezilungileyo nezingalunganga, nto leyo eya kubangela ukuba ipali yeplatinum ingcoliswe kwaye ixabiso le-thermoelectric potential lehle.

3. Ngokungacwangciswanga ityhubhu yokukhusela i-thermocouple eqhelekileyo enentambo engabizi iya kungcolisa i-thermocouple eqhelekileyo, kwaye ityhubhu yesinyithi ekhuselayo kufuneka isetyenziswe ukuqinisekisa i-thermocouple yesinyithi esisiseko.

4. I-thermocouple eqhelekileyo ayinakubekwa ngequbuliso kwisithando somlilo esilawula ubushushu, kwaye ayinakukhutshwa kwisithando somlilo esilawula ubushushu. Ubushushu nokubanda ngequbuliso kuya kuchaphazela ukusebenza kwe-thermoelectric

5. Phantsi kweemeko eziqhelekileyo, isithando sokuqinisekisa i-thermocouple yesinyithi esixabisekileyo kunye ne-thermocouple yesinyithi esisisiseko kufuneka sahlulwe ngokungqongqo; ukuba akunakwenzeka, ityhubhu yeseramikhi ecocekileyo okanye ityhubhu ye-corundum (ububanzi obumalunga ne-15mm) kufuneka ifakwe kwityhubhu yesithando somlilo ukukhusela ii-Thermocouple zesinyithi esixabisekileyo kunye nee-thermocouple ezisemgangathweni kungcoliseko lwe-thermocouple yesinyithi esisisiseko.
