Ukuhlolwa kokushisa kwenzwa yokusebenza kanye nokukhethwa kokukhethwa

Umsebenzi we-thermocouple usebenza kanjani

Lapho kunabaqhubi abahlukahlukene abahlukene kanye nama-semiconductors a no-B ukwakha i-loop, futhi amazinga womabili axhumeke komunye nomunye, okushisa okukodwa, okungukuphela kokuphela, okungukuthi, amandla e-electromotive akhona ku-loop abizwa ngokuthi ama-thermoelectromotive Force. Le nto yokukhiqiza amandla e-electromotive ngenxa yokwehlukana kwezinga lokushisa ibizwa ngokuthi yi-Seebeck Effect. Kunemiphumela emibili ehlobene ne-Seebeck: Okokuqala, lapho ukugeleza kwamanje ngomngcele wabaqhubi abahlukahlukene abahlukahlukene, ukushisa kuyamangazwa noma kukhishwe lapha (kuya ngokuqondiswa kwe-Pelt), okubizwa ngokuthi yi-Peltic Effect; Okwesibili, lapho ukugeleza kwamanje ngomqhubi onamazinga okushisa, umqhubi we-conductor amunca noma akhiphe ukushisa (kuya ngesiqondiso sesihlobo samanje sokushisa kwe-gradient), eyaziwa ngokuthi iThomson Effect. Inhlanganisela yabaqhubi ababili abahlukene noma ama-semiconductors abizwa nge-thermocouple.

I-Sensors Iphikisana Kanjani

Inani lokumelana le-Conductor izinguquko ngokushisa, futhi izinga lokushisa lento elizolinganiswa libalwa ngokulinganisa inani lokumelana. Inzwa eyenziwe ngumgomo yinzwa yokumelana yokumelana, esetshenziselwa kakhulu amazinga okushisa ebangeni lokushisa le-200-500 ° C. Isilinganiso. I-Pure Metal iyizinto eziphambili zokukhiqiza zokumelana okushisayo, futhi okubonakalayo kokumelana okushisayo kufanele kube nezimpawu ezilandelayo:

.

(2) Ukumelana okuphezulu, umthamo omncane wokushisa kanye nesivinini sokusabela okusheshayo.

(3) Izinto ezibonakalayo zinokuzala okuhle nobungcweti, futhi intengo iphansi.

(4) Izakhiwo zamakhemikhali nezomzimba zizinzile ngaphakathi kobubanzi bokulinganisa bokushisa.

Njengamanje, iplatinamu ne-zethusi yiyona esetshenziswa kakhulu embonini, futhi yenziwe ekulweni okujwayelekile kokumelana nokushisa okushisayo.

Ukucatshangelwa lapho ukhetha inzwa yokushisa

1. Ukuthi izimo zemvelo zento elinganisiwe zinokulimala kwento yokulinganisa lokushisa.

2. Ukuthi izinga lokushisa lento elinganisiwe lidinga ukuqoshwa, zethuse futhi kulawulwa ngokuzenzakalelayo, nokuthi kudingeka lulinganiswe futhi kudluliselwe ukude. 3800 100

3

4. Ubukhulu nokunemba kwebanga lokulinganisa lokushisa.

5. Ukuthi usayizi wento yokulinganisa lokushisa kufanelekile.

I-6. Intengo iqinisekisiwe nokuthi kufanelekile ukuyisebenzisa.

Ungakugwema Kanjani Amaphutha

Lapho ufaka futhi usebenzisa inzwa yokushisa, amaphutha alandelayo kufanele agwenywe ukuqinisekisa umphumela omuhle kakhulu wokulinganisa.

1. Amaphutha adalwa ukufakwa okungafanele

Isibonelo, isikhundla sokufaka kanye nokujula kokufaka kwe-thermocouple akunakubonisa izinga lokushisa langempela lesithando. Ngamanye amagama, i-thermocouple akufanele ifakwe eduze kakhulu emnyango nasekushiseni, futhi ukujula kokufakwa kufanele okungenani kube izikhathi eziyi-8 kuye kwezingu-10 ububanzi be-tube yokuvikela.

2. Iphutha lokumelana ne-Thermal

Lapho izinga lokushisa liphezulu, uma kukhona ungqimba lomlotha wamalahle kwishubhu elivikelayo nothuli lunamathele kulo, ukumelana okushisayo kuzokhulisa futhi kuvimbele ukufakwa kokushisa. Ngalesi sikhathi, inani lezinkomba zokushisa liphansi kunenani leqiniso lokushisa okulinganiselwe. Ngakho-ke, ingaphandle ye-thermocouple yokuvikela ishubhu kufanele igcinwe ihlanzekile ukunciphisa amaphutha.

3. Amaphutha abangelwa ukufakwa okungalungile

Uma i-thermocouple ifakwa, ukungcola ngokweqile noma usawoti we-slag ku-tube yokuvikela futhi ibhodi lokudweba le-wire lizoholela ekufakweni kabi phakathi kwe-thermocouple kanye nodonga olubi kakhulu, olungeke ludale khona ukuthi kulahlekelwe amandla ama-thermoelectric kodwa futhi wethule ukuphazamiseka. Iphutha elibangelwa lokhu kwesinye isikhathi lingafinyelela iBaidu.

4. Amaphutha angeniswe yi-inertia eshisayo

Lo mphumela ukhulunywa ngokukhethekile lapho wenza izilinganiso ezisheshayo ngoba i-thertia ye-thertia ye-thermocouple ibangela ukubaluleka kwamamitha abonisiwe ukuba asuswe ngemuva koshintsho ekushiseni okulinganiswayo. Ngakho-ke, i-thermocouple nge-electrode encane ye-thermal kanye nobubanzi obuncane beshubhu lokuvikela kufanele busetshenziswe ngangokunokwenzeka. Lapho imvelo yokulinganisa yokulinganisa, ishubhu elivikelayo lingasuswa. Ngenxa ye-lag yokulinganisa, ukuguquguquka kokushisa okutholwe yi-thermocouple kuncane kunokuguquguquka kokushisa komlilo. Lapho likhudlwana i-lag yokulinganisa, incane ukuguquguquka kokushintshashintsha kwe-thermocouple kanye nomehluko omkhulu kusuka ekushiseni kwe-hola yangempela.
