Ziziphi iintlobo zeplatinam-rhodium thermocouples?
Kukho iintlobo ezintathu eziphambili zeiplatinam-rhodium thermocouples: Udidi lwe-B, uhlobo lwe-R, kunye nohlobo lwe-S. Ezi thermocouples ziyaziwa ngokuzinza kwazo okuphezulu kwaye zihlala zisetyenziselwa izicelo ezifuna umlinganiselo ochanekileyo wokushisa.
1. Uhlobo B (iPlatinum 30% Rhodium / Platinum 6% Rhodium): Uluhlu lweqondo lokushisa: 0 ° C ukuya ku-1700 ° C, Iimpawu: Uhlobo lwe-thermocouples lwe-B luzinzile kwaye lunokulinganisa ukushisa okuphezulu kakhulu. Ngokuqhelekileyo isetyenziswa kwiziko lobushushu obuphezulu kunye neekhilni.
2. Uhlobo lwe-R (i-Platinum 13% i-Rhodium / i-Platinum): Uluhlu lobushushu: -50 ° C ukuya kwi-1600 ° C, Iimpawu: Uhlobo lwe-thermocouples lwe-R lubetha ibhalansi elungileyo phakathi kweendleko kunye nokusebenza. Zisetyenziswa kwiintlobo ngeentlobo zezicelo zamashishini ezibandakanya ukuveliswa kweglasi kunye nokulungiswa kwesinyithi.
3. Uhlobo lwe-S (i-Platinum 10% i-Rhodium / i-Platinum): Uluhlu lobushushu: -50 ° C ukuya kwi-1600 ° C, Iimpawu: Uhlobo lwe-thermocouples luyaziwa ngokuchaneka kunye nokuzinza. Ngokuqhelekileyo zisetyenziswa kwiilabhoratri nakwimizi-mveliso apho ulawulo oluchanekileyo lobushushu lubalulekile.
Loluphi olona cingo lwe-thermocouple?
Injongo yokugweba umgangatho wemveliso ilele kumgangatho wayo. Iimveliso ezahlukeneyo zinemigangatho yomgangatho ohlukeneyo, kwaye umgangatho we-platinum-rhodium ucingo lwe-thermocouple unokugwetywa kwiimpawu ezine ezilandelayo. Okokuqala, ucingo lweplatinam-rhodium lunozinzo oluphezulu lobushushu kwaye lunokumelana namaqondo obushushu aphezulu kakhulu ngaphandle kokuthotywa. Oku kuzinza kuqinisekisa umlinganiselo ochanekileyo weqondo lokushisa phezu koluhlu olubanzi lobushushu. Okwesibini, i-platinum-rhodium thermocouples inika umlinganiselo ochanekileyo wokushisa, okwenza kube yinto efanelekileyo kwizicelo ezifuna ukuchaneka okungqongqo. Ukongezelela, iplatinam kunye ne-rhodium nazo zinokumelana okuphezulu kwe-corrosion, iqinisekisa ubomi benkonzo kunye nokuthembeka kocingo lwe-thermocouple kwiindawo ezinzima. Ukuqina kweplatinum-rhodium thermocouple wire yenza ukuba ilungele ukusetyenziswa kwexesha elide kwizicelo zoshishino, ukunciphisa imfuno yokutshintshwa rhoqo. Ukuba iimfuno zokulinganisa ukuchaneka, ukuzinza, ukuxhathisa i-oxidation, njl., ziphezulu kakhulu, iplatinam-rhodium thermocouple wire iyona nto ingcono kakhulu.
Yintoni ukusetyenziswa kweplatinam thermocouple wire?
Iplatinam thermocouple wireyinxalenye ephambili ekwakhiweni kweplatinum-rhodium thermocouples. Iimpawu zayo ezikhethekileyo zenza iplatinam-rhodium ucingo lwe-thermocouple olufanelekileyo kwiintlobo ezahlukeneyo zokushisa okuphezulu. Kwishishini le-aerospace, ucingo lweplatinam thermocouple lusetyenziselwa ukulinganisa ubushushu beenjini zejethi kunye namanye amacandelo obushushu obuphezulu. Umlinganiselo ochanekileyo wokushisa ubalulekile kukhuseleko kunye nokusebenza kwezixhobo ze-aerospace. I-Platinum thermocouple wire isetyenziswa kwiziko zoshishino ukujonga nokulawula amaqondo obushushu aphezulu. Ukuzinza kwabo kunye nokuchaneka kwabo kuqinisekisa ukuba isithando somlilo sisebenza ngaphakathi kweqondo lokushisa elifunekayo, ngaloo ndlela liphucula ukusebenza kakuhle kunye nomgangatho wemveliso. Ukongeza, inkqubo yokwenziwa kweglasi ifuna ulawulo oluchanekileyo lobushushu, kwaye iplatinam yocingo lwe-thermocouple isetyenziselwa ukubeka esweni ubushushu beziko leglasi ukuqinisekisa ukuveliswa kweglasi okuhambelanayo kunye nomgangatho ophezulu. Kuphando lwezenzululwazi, umlinganiselo ochanekileyo wokushisa ubalulekile kwiimvavanyo kunye nokuqokelela idatha. I-Platinum thermocouple wire isetyenziselwa ukulinganisa ubushushu kwiimvavanyo ezahlukeneyo kwibhubhoratri, ukubonelela ngedatha ethembekileyo nechanekileyo.
I-Platinum-rhodium thermocouples (kubandakanywa neentlobo ze-B, i-R, kunye ne-S) zizixhobo ezibalulekileyo zokulinganisa ngokuchanekileyo izinga lokushisa kwizicelo eziphezulu zokushisa. Xa ukhetha ucingo olungcono kakhulu lwe-thermocouple, i-platinum-rhodium thermocouples idla ngokuba yinto yokuqala kuba iqhuba kakuhle kwiindawo ezinzima. I-Platinum-rhodium thermocouples idlala indima ebalulekileyo kumashishini ahlukeneyo, inika ukuchaneka kunye nokuzinza okufunekayo kwizicelo eziphezulu zokushisa.
