Imiqathango yofakelo lwe iziko lomlilo

Isithando somlilo se-muffle sineempawu zesantya sokufudumeza ngokukhawuleza, umphumo omuhle wokugquma, ukhuseleko oluphezulu, kunye nokhuseleko kunye nokuthembeka. Isetyenziswe ngokubanzi kwi-thermal processing of workpieces encinci, kunye nokuhlola kunye nohlalutyo. Izinto ezilungileyo zinokusetyenziswa ngokubanzi, kodwa izinto ezilungileyo azinakwahlulwa ekusebenzeni okuchanekileyo nokukhuselekileyo. Masikuthathe uqonde amanyathelo okhuseleko ofakelo, ngolu hlobo lulandelayo:

1. Emva kokuvula ipakethe, khangela ukuba i-furnace ye-muffle ilungile kwaye ingaba izesekeli zigqityiwe.

2. I-furnace ye-muffle ngokubanzi ayifuni ukufakela okukhethekileyo. Kufuneka kuphela ibekwe mcaba kwitafile yesamente eqinileyo okanye kwishelufa ngaphakathi endlini, kwaye akufuneki kubekho izinto ezinokutsha neziqhumayo macala onke. Umlawuli kufuneka agweme ukungcangcazela, kwaye indawo akufanele isondele kakhulu kwisithando sombane ukukhusela amacandelo angaphakathi ukuba angasebenzi kakuhle ngenxa yokushisa.

3. Faka i-thermocouple kwisithando somlilo kwi-20-50mm, kwaye ugcwalise isithuba phakathi komngxuma kunye ne-thermocouple ngentambo ye-asbestos. Xhuma i-thermocouple kwintambo yokuhlawula umlawuli (okanye sebenzisa i-insulated steel core wire), nikela ingqalelo kwiipali ezilungileyo kunye nezibi, kwaye ungazixhumi ngokuphindaphindiweyo.

4. Ukutshintsha kwamandla kufuneka kufakwe kwintambo yombane ekhokelela ekulawuleni umbane ongundoqo. Ukuze kuqinisekiswe ukusebenza okukhuselekileyo, isithando somlilo se-muffle kunye nomlawuli kufuneka sisekelwe ngokuthembekileyo.

5. Ngaphambi kokusetyenziswa, lungisa i-thermostat kwindawo ye-zero. Xa usebenzisa ucingo lwembuyekezo kunye nesixhasi sesiphambuka esibandayo, lungisa indawo ye-zero yomatshini ukuya kwindawo yereferensi yobushushu bomxhasi wesiphambuka esibandayo. Xa ucingo lwembuyekezo lungasetyenziswanga, indawo ye-zero yomatshini iyalungiswa. Kwindawo yesikali esingu-zero, kodwa iqondo lobushushu libonisiwe ngumahluko wobushushu phakathi kwendawo yokulinganisa kunye nesiphambuka esibandayo se-thermocouple.

6. Lungisa ubushushu obumiselweyo kwiqondo lobushushu elifunekayo, uze uvule amandla. Vula umsebenzi, i-furnace ye-muffle inamandla, kwaye igalelo langoku, i-voltage, amandla aphumayo kunye nobushushu bexesha langempela liboniswa kwipaneli yokulawula. Njengoko ukushisa kwangaphakathi kwesithando sombane sanda, iqondo lokushisa langempela liya kwanda. Lo mcimbi ubonisa ukuba inkqubo isebenza ngokuqhelekileyo.
