Izithasiselo Zokulawula Ukulahlekelwa Uketshezi ze-FC-631S
• I-FC-631S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-simende slurry. Ihambisana kahle nezinye izithasiselo.
• I-FC-631S inobuthi obukhulu besilinganiso esiphansi sokucheba, okungathuthukisa ngempumelelo ukuzinza kokumiswa kohlelo lwe-slurry lwesimende, kugcinwe ukugeleza kwe-slurry, kuvimbele ukuchitheka kwenhlabathi ngesikhathi esifanayo, futhi kube nokusebenza okuhle kokuvimbela igesi.
• I-FC-631S ifaneleka ekushiseni okubanzi okunokumelana nokushisa okuphezulu okufika ku-230℃. Ngemva kokusetshenziswa, ukugeleza kohlelo lwe-slurry lukasimende kuhle, kuzinzile ngoketshezi olukhululekile oluncane futhi aludingi ukulibaziseka futhi amandla okuqala ekushiseni okuphansi akhula ngokushesha.
• I-FC-631S ingasetshenziswa yodwa. Umphumela uba ngcono uma isetshenziswa kanye ne-FC-650S.
• I-FC-631S ifaneleka ekulungiseleleni ukungcola kwamanzi ahlanzekile.
Izinkambu zikawoyela ezinokushisa okuphezulu zibhekene nezinselelo ezihlukile uma kukhulunywa ngokufakwa kwesimende emthonjeni. Enye yalezi zinselelo yinkinga yokulahleka koketshezi, okungenzeka lapho i-filtrate yodaka lokubhoboza ihlasela ukwakheka futhi ibangele ukwehla komthamo woketshezi. Ukuze sixazulule le nkinga, sithuthukise umshini wokunciphisa ukulahleka koketshezi okhethekile owenzelwe ngqo ukusetshenziswa ezinkambu zikawoyela ezinokushisa okuphezulu. I-FC-631S uhlobo lokulawula ukulahleka koketshezi futhi ifaneleka emakethe yaseRussia naseNyakatho Melika.

Sekuyiminyaka engaphezu kwengu-20, izinto zokulawula ukulahlekelwa uketshezi ziye zengezwa ezitsheni zesimende ezisebenzisa uwoyela futhi manje sekuyaziwa embonini ukuthi ikhwalithi yemisebenzi yokufaka usimende ithuthuke kakhulu. Ngempela, ngokuvamile kuyavunywa ngokucacile ukuthi ukuntuleka kokulawulwa kokulahlekelwa uketshezi kungaba yimbangela yokwehluleka kokuqala kokufaka usimende, ngenxa yokwanda kobuningi noma ukuvalwa kwe-annulus nokuthi ukuhlasela kokwakheka yi-cement filtrate kungaba yingozi ekukhiqizweni. Isengezo sokulahlekelwa uketshezi asikwazi nje ukulawula ngempumelelo ukulahlekelwa uketshezi kwesimende, kodwa futhi sivimbele ungqimba lukawoyela negesi ekungcolisweni uketshezi oluhlungiwe futhi ngaleyo ndlela kwandise ukusebenza kahle kokubuyisela esimweni saso.
