Izinyathelo Zokukhethwa Kwezinzwa Zokushisa Nezindlela Zokugwema Amaphutha

Ⅰ. Ukuqapha kokukhetha izinzwa zokushisa

1. Ngabe izimo zemvelo zento elilinganisiwe zinomonakalo yini kwinto yokulinganisa izinga lokushisa.

2. Ukuthi izinga lokushisa lento elilinganisiwe lidinga ukurekhodwa, lithukile futhi lilawulwe ngokuzenzakalela, nokuthi kudingeka yini ukulinganiswa nokudluliswa kude.

3. Esimweni lapho izinga lokushisa lento elilinganisiwe lishintsha ngokuhamba kwesikhathi, ngabe ukulinganisa kokulinganisa kokushisa kungahlangabezana nezidingo zokulinganisa izinga lokushisa.

4. Usayizi nokunemba kwebanga lokulinganisa lokushisa.

5. Ukuthi usayizi wento yokulinganisa izinga lokushisa uyafanele yini.

Iyini inani nokuthi kulula yini ukuyisebenzisa.

Ⅱ. Ungagwema kanjani amaphutha ezinzwa zezinga lokushisa?

Lapho ufaka nokusebenzisa inzwa yokushisa, amaphutha alandelayo kufanele agwenywe ukuqinisekisa umphumela ongcono wokulinganisa.

1. Amaphutha abangelwa ukufakwa okungalungile

Isibonelo, indawo yokufakwa nokujula kokufakwa kwe-thermocouple akukwazi ukukhombisa izinga lokushisa langempela lesithando. Ngamanye amagama, i-thermocouple akufanele ifakwe eduze kakhulu emnyango nokushisa, futhi ukujula kokufakwa kufanele kube okungenani izikhathi eziyi-8 kuye kwezingu-10 ububanzi besishubhu sokuvikela.

2. Iphutha lokumelana nokushisayo

Lapho izinga lokushisa liphakeme, uma kukhona ungqimba lomlotha wamalahle eshubhu esivikelayo nothuli olunamathiselwe kuyo, ukumelana nokushisa kuzokhuphuka futhi kuvimbele ukuqhutshwa kokushisa. Ngalesi sikhathi, inani lokubonisa izinga lokushisa liphansi kunenani langempela lokushisa elilinganisiwe. Ngakho-ke, ingaphandle kweshubhu lokuvikela i-thermocouple kufanele igcinwe ihlanzekile ukunciphisa amaphutha.

3. Amaphutha abangelwa ukufakwa okungekho

Uma i-thermocouple ihlanganiswe, Ukungcola okukhulu kakhulu noma usawoti i-slag eshubhu sokuvikela kanye nebhodi lokudweba ngocingo lizoholela ekufakweni okungafanele phakathi kwe-thermocouple ne- udonga lwezithando, okubi kakhulu emazingeni okushisa aphezulu, okungeke kudale kuphela ukulahleka kwamandla e-thermoelectric kepha futhi kwethule ukuphazamiseka. Iphutha elibangelwe yilokhu kwesinye isikhathi lingafinyelela ku-100℃.

4. Amaphutha avelwe yi-thermal inertia

Lo mphumela ubizwa ikakhulukazi lapho wenza izilinganiso ezisheshayo ngoba i-thermal inertia ye-thermocouple ibangela imita inani elikhombisiwe lokuncipha ngemuva koshintsho ekushiseni okulinganiswayo. Ngakho-ke, i-thermocouple ene-electrode eshisayo encane kanye nobubanzi obuncane besishubhu sokuvikela kufanele sisetshenziswe ngangokunokwenzeka. Lapho indawo yokulinganisa izinga lokushisa ivumela, ishubhu elivikelayo lingasuswa ngisho. Ngenxa yesilinganiso sokulinganisa, i-amplitud yokuguquguquka kokushisa okutholwe yi-thermocouple incane kunaleyo yokuguquguquka kokushisa komlilo. Uma kukhulu ukulinganisa, okuncane i-amplitude yokuguquguquka kwe-thermocouple futhi kukhulu umehluko kusuka ekushiseni komlilo wangempela.

I-LEFOO ibhizinisi likazwelonke lobuchwepheshe obuphezulu elidlulise isitifiketi esigunyazayo sohlelo lwekhwalithi ye-TUV ISO9001 kanye ne-IS014001 uhlelo lwezemvelo. Imikhiqizo eyinhloko iyahambisana ne-CE, RoHS, REACH, FDA, CQC nezinye izitifiketi. I-LEFOO ithuthukisa futhi ikhiqize ukulawulwa kwengcindezi ejwayelekile ephezulu, imishini yokulawula izinga lokushisa, ukuhlinzeka ngezixazululo ezintsha nezinto ezintsha. Ukwamukela ukubonisana.
