PR1231/PR1232 iPlatinam esemgangathweni-10% iRhodium/iPlatium Thermocouple

Part1 Isishwankathelo

Umgangatho wokuqala kunye nomgangatho wesibini weplatinam-iridium 10-platinum thermocouples ezinokuchaneka okuphezulu okuhle ngokomzimba kunye neempawu zemichiza, ukumelana ne-oxidation efanelekileyo kumaqondo aphezulu okushisa, ukuzinza okulungileyo kunye nokuphindaphinda kwamandla e-thermoelectromotive.Ngoko ke, isetyenziswe njengesixhobo sokulinganisa esisemgangathweni kwi (419.527 ~ 1084.62) °C, iphinda isetyenziswe ukuhambisa ubukhulu beqondo lokushisa kunye nomlinganiselo ochanekileyo wokushisa kwiqondo lokushisa.

Icandelo3 Imiyalelo yesicelo

umgangatho weplatinam-iridium 10-platinum thermocouples kufuneka ihambelane netheyibhile yenkqubo yonikezelo kazwelonke,Kufuneka kuphunyezwe iinkqubo zokuqinisekisa kaZwelonke.Ibanga lokuqala eliqhelekileyo iplatinam-iridium 10-platinum thermocouples ingasetyenziselwa ukulinganisa ibakala lesibini,Ⅰ ibakala,Ⅱ ibakala leplatinam-iridium 10-platinum thermocouples kunye Ⅰ isiseko somgangatho we-thermocouples zentsimbi;Iplatinam-iridium yenqanaba lesibini Ithermocouples yeplatinam ingasetyenziswa kuphela ukulinganisa Ⅱ isiseko sesiseko sesinyithi sethermocouples

Ikhowudi yokuqinisekisa yelizwe	Igama lokuqinisekisa lesizwe
JJG75-1995	umgangatho weplatinam-iridium 10-platinum thermocouples ukulinganisa ukulinganisa

Icandelo 4 Ugcino nogcino

1. Ixesha lokulinganisa i-thermocouple calibration ngunyaka we-1, kwaye minyaka yonke i-standard thermocouple kufuneka ilinganiswe lisebe le-metrology.

2. Ulungelelwaniso oluyimfuneko lokusuphavayiza kufuneka lwenziwe ngokosetyenziso.

3. Indawo yokusebenza ye-thermocouple eqhelekileyo kufuneka ihlambuluke ukuze igweme ukungcoliswa kwe-standard thermocouple.

4. Umgangatho we-thermocouple kufuneka ubekwe kwimeko engangcolisi kwaye ukhuselwe kuxinzelelo lomatshini.

Icandelo5 Ulumkeleko xa usetyenziswa

1. I-tube ye-insulation ayikwazi ukusetyenziswa kwiqondo lokushisa eliphezulu lokutshisa.I-tube yokuqala yokugquma isetyenziswe emva kokucoca ngokungqongqo kunye nokutshisa ukushisa okuphezulu.

2. I-tube ye-insulation iyayihoxisa i-positive kunye ne-negative, eya kubangela ukuba i-platinum pole ingcolise kwaye ixabiso le-thermoelectric liyancipha.

3. Ngokuzenzekelayo umbhobho wokugquma we-thermocouple oqhelekileyo kunye nocingo oluncinci luya kungcolisa umgangatho we-thermocouple, kwaye ityhubhu yentsimbi ekhuselayo kufuneka isetyenziselwe ukuqinisekiswa kwesiseko sensimbi ye-thermocouple.

4. I-thermocouple esemgangathweni ayikwazi ukufakwa ngokukhawuleza kwisithando sokushisa, okanye ikhutshwe kwisithando somlilo esilawula ukushisa.Ukushisa ngokukhawuleza kunye nokubanda kuya kuchaphazela ukusebenza kwe-thermoelectric

5.Ngaphantsi kweemeko eziqhelekileyo, i-furnace yokuqinisekisa ye-thermocouple yensimbi exabisekileyo kunye nesiseko se-metal thermocouple kufuneka ihluke ngokuthe ngqo;ukuba akunakwenzeka, ityhubhu ye-ceramic ecocekileyo okanye ityhubhu ye-corundum (ububanzi malunga ne-15mm) kufuneka ifakwe kwityhubhu yesithando sokukhusela i-Thermocouples yentsimbi exabisekileyo kunye ne-thermocouples esemgangathweni ukusuka kwisiseko songcoliseko lwe-metal thermocouple.
