Induku yensimbi eqhubekayo yokushisisa isithando somlilo

Induku yensimbi eqhubekayo yokushisisa isithando somlilo

Ezimbonini zensimbi nemishini yokukhiqiza, lapho okukhiphayo kukhulu, okuqhubekayo indlela yokushisa engenayo ngoba imigoqo yensimbi manje isisetshenziswa kakhulu. Ngemva kokuba induku yensimbi ishisiwe, ifakwa ngaphansi kokugunda okushisayo, bese ifa ngokubumba noma ukunyathela.

Umfanekiso 12-51 isethi yensimbi yensimbi imvamisa ephakathi nendawo eqhubekayo yokushisa yokungeniswa kwesithando somlilo. Induku yensimbi ibekwa endaweni yesikhulumi esidlidlizayo sendawo yokudla, bese idonselwa emgwaqeni wokuphakelayo ngomshini wokudonsa othomathikhi, oshayelwa ukulawulwa kwesivinini esingenasinyathelo se-DC motor. I-feed roller iphakela ibha ku-inductor ukuze ifudumale. Inombolo yezinzwa inqunywa ngokuya ngobubanzi bebha kanye nokuphumayo. Lezi zinzwa zihlelwe ngendlela eqondile. Lesi sithando somlilo esiqhubekayo sokushisisa sisetshenziselwa ukushisisa izinsimbi zensimbi ezinobude obungu-Φ55 – Φ 100 mm nobude obungu-6m. Izinga lokushisa lokushisisa ngu-t = 1200℃±25Y, okungukuthi, umehluko wezinga lokushisa phakathi kwendawo kanye nengqikithi yebha ngu-50℃, futhi ukukhiqiza kungu-3600kg/h. I-inverter ye-thyristor inikwe amandla, imvamisa ingu-1100Hz, amandla angu-1 320kW, futhi imingcele efanelekile ye-inductor iboniswa kuThebula 12-10.

Ama-inductors ahlukaniswe ngamaqembu amathathu ngokusho kobubanzi bezinduku zensimbi. Lapho ushisa izinti zensimbi zama-diameter ahlukene, ama-inductors ahambisanayo kufanele ashintshwe. Kungafakwa ama-inductors afinyelela kwayi-10 esithandweni sokushisa sokungeniswa. Ubude bekhoyili be-inductor bungama-550mm. Ngemuva kokwelashwa kwe-insulation, ikhoyili ihlanganiswe nesendlalelo sokushisa ukushisa esenziwe ngoboya bamaminerali kanye nesendlalelo esimelana nokushisa esenziwe ngezinto eziphikisayo. Ekugcineni, ibhodi likasimende le-asbestos lisetshenziselwa ukwenza ibhokisi, futhi ikhoyili igxilile ebhokisini. . Ubude bebhokisi ngalinye buyi-600mm, ibanga lokufaka phakathi kwebhokisi nebhokisi lingama-200mm, futhi isikhulumi sokuphakelayo sifakwe phakathi.

Ukunikezwa kwamandla kwe-inductor ukuthi ama-inductors amabili axhunywe ochungechungeni kuqala, bese exhunywe ngokufana emgqeni wokuhlinzeka amandla, njengoba kuboniswe kuMfanekiso 12-52.

Umfanekiso 12-53 ulayini wokukhiqiza oqhubekayo wokushisisa owenziwe yinkampani yangaphandle enamandla angu-12MW, ingqikithi yama-inductors angu-26, nobude obuphelele obuyi-157 m (47.86m) .
