I-PR1231/PR1232 I-Thermocouple Ejwayelekile Yeplatinum-10% Rhodium/Platium

Ukubuka Konke Kwengxenye 1

Ama-thermocouple e-platinum-iridium 10-platinum asezingeni lokuqala nelesibili anezakhiwo ezinhle zomzimba nezamakhemikhali, ukumelana okuhle kwe-oxidation emazingeni okushisa aphezulu, ukuzinza okuhle kanye nokuphindaphindeka kwamandla e-thermoelectromotive. Ngakho-ke, isetshenziswa njengethuluzi lokulinganisa elijwayelekile ku-(419.527~1084.62) °C, isetshenziselwa futhi ukudlulisa ubukhulu bokushisa kanye nokulinganisa izinga lokushisa ngokunemba ebangeni lokushisa.

Ingxenye 3 Imiyalelo Yokusebenzisa

Ama-thermocouple ajwayelekile e-platinum-iridium 10-platinum kumele ahambisane nethebula lohlelo lokulethwa lukazwelonke, kumele kuqaliswe izinqubo zokuqinisekisa zikazwelonke. Ama-thermocouple ajwayelekile e-platinum-iridium 10-platinum angasetshenziswa ukukala ama-thermocouple e-grade yesibili, ibanga le-Ⅰ, ibanga le-Ⅱ le-platinum-iridium 10-platinum kanye nama-thermocouple ensimbi ayisisekelo se-Ⅰ; Ama-thermocouple e-platinum-iridium 10-platinum angasetshenziswa kuphela ukukala ama-thermocouple ensimbi ayisisekelo se-Ⅱ.

Ikhodi yokuqinisekisa kazwelonke	Igama lokuqinisekisa likazwelonke
JJG75-1995	incazelo ejwayelekile yokulinganisa i-platinum-iridium 10-platinum thermocouples
JJG141-2013	Imininingwane yokulinganisa i-thermocouple yensimbi eyigugu esebenzayo

Ingxenye 4 Ukugcinwa Nokulondolozwa

1. Isikhathi sokulinganisa i-thermocouple ejwayelekile singunyaka owodwa, futhi njalo ngonyaka i-thermocouple ejwayelekile kumele ilinganiswe umnyango we-metrology.

2. Ukuhlolwa kokuqapha okudingekayo kufanele kwenziwe ngokwendlela okusetshenziswa ngayo.

3. Indawo yokusebenza ye-thermocouple ejwayelekile kufanele ihlanzeke ukuze kugwenywe ukungcoliswa kwe-thermocouple ejwayelekile.

4. I-thermocouple ejwayelekile kufanele ibekwe endaweni engangcolisi futhi ivikelwe ekucindezelekeni komshini.

Ingxenye 5 Izinyathelo Zokuqapha Uma Usebenzisa

1. Ishubhu lokuvikela alikwazi ukusetshenziswa ekushiseni okuphezulu. Ishubhu lokuqala lokuvikela lisetshenziswa ngemva kokuhlanza okuqinile kanye nokushiswa okuphezulu.

2. Ishubhu lokuvikela alinaki okuhle nokubi, okuzobangela ukuthi i-platinum pole ingcoliswe kanye nenani lamandla okushisa linciphe.

3. Ngokungahleliwe ishubhu yokushisa ye-thermocouple ejwayelekile enentambo eshibhile izongcolisa i-thermocouple ejwayelekile, futhi ishubhu yensimbi evikelayo kumele isetshenziselwe ukuqinisekisa i-thermocouple yensimbi eyisisekelo.

4. I-thermocouple ejwayelekile ayikwazi ukufakwa ngokuzumayo esithandweni esilawula izinga lokushisa, futhi ayikwazi ukukhishwa esithandweni esilawula izinga lokushisa. Ukushisa nokubanda okuzumayo kuzothinta ukusebenza kwe-thermoelectric

5. Ngaphansi kwezimo ezijwayelekile, isithando sokuqinisekisa se-thermocouple yensimbi eyigugu kanye ne-thermocouple yensimbi eyisisekelo kufanele sihlukaniswe ngokuqinile; uma kungenzeki, ithubhu ye-ceramic ehlanzekile noma ithubhu ye-corundum (ububanzi obungaba ngu-15mm) kufanele ifakwe ethubhu yesithando somlilo ukuze kuvikelwe ama-Thermocouple ensimbi eyigugu kanye nama-thermocouple ajwayelekile ekungcolisweni kwe-thermocouple yensimbi eyisisekelo.
