Matumba atatu-akusefa fumbi osaona amanena za ntchito zoteteza madzi, mafuta-kuletsa-kuipitsa, zomwe ndi zofunika kwambiri kuonetsetsa kuti zikwama zosefera zikuyenda bwino komanso kuti nthawi zonse zizigwira ntchito bwino.
Mu kupanga mafakitale, fumbi fyuluta matumba ndi chimodzi mwa zipangizo zofunika kwambiri. Komabe, matumba fyuluta fumbi nthawi zambiri amakumana zosiyanasiyana zovuta zachilengedwe zinthu pa ntchito, monga kutentha kwambiri, chinyezi mkulu, kuipitsidwa mafuta, etc. Zinthu zimenezi zingakhudze ntchito ndi moyo wa fumbi fyuluta matumba. Kuti tithane ndi mavutowa, zikwama zosefera fumbi zimayenera kukhala ndi-zigawo zitatu zotsimikizira kuti zisalowe m'madzi, mafuta{4}}akuteteza ndi kuletsa-kuipitsa.
1. Ntchito yopanda madzi
Ntchito yopanda madzi imatanthawuza kuti thumba la fyuluta la fumbi limatha kukhalabe ndi mpweya wake woyambirira komanso kusefera m'malo onyowa kapena onyowa. Pamene fumbi fyuluta thumba anaukira ndi chinyezi, chinyezi kutsekereza pores a thumba fyuluta, kuchititsa kuchepetsa permeability mpweya ndi kuchepetsa kusefera kwenikweni. Chifukwa chake, matumba a fyuluta a fumbi okhala ndi ntchito yopanda madzi amatha kukhalabe osasunthika m'malo achinyezi kuti awonetsetse kuti pulogalamu yochotsa fumbi imagwira ntchito bwino.
2. Kugwira ntchito kwamafuta{1}}
Kugwira ntchito kwamafuta-kumatanthauza kuti chikwama chosefera fumbi chimatha kukana kukokoloka kwa mafuta ndikukhalabe aukhondo komanso kusefa kwake. Popanga mafakitale, zowononga monga utsi wamafuta ndi nkhungu zamafuta zimatha kuwononga kwambiri thumba lazosefera zafumbi, zomwe zimabweretsa mavuto monga kutsekeka kwa thumba la fyuluta ndikuwumitsa. Matumba osefera fumbi okhala ndi mafuta-amatha kukhala aukhondo m'malo amafuta, kuwonjezera moyo wantchito, ndikusintha kusefa moyenera.
3. Anti{1}}ntchito yoyipa
Kuletsa-kuipitsa kumatanthauza kuti chikwama chosefera fumbi chimatha kukana kukokoloka kwa zinthu zosiyanasiyana zoipitsa ndikukhalabe ndi mawonekedwe ake oyamba. Pakupanga mafakitale, fumbi losiyanasiyana, zinthu zina ndi zowononga zina zimatha kuwononga thumba la fyuluta, zomwe zimabweretsa mavuto monga kukalamba ndi kusweka kwa thumba la fyuluta. Matumba osefera fumbi okhala ndi -ntchito yoipa amatha kuthana ndi kukokoloka kwa zinthu zoipitsazi, kupitiriza kugwira ntchito ndi maonekedwe ake, komanso kupititsa patsogolo ntchito yochotsa fumbi komanso moyo wawo wonse.
Mwachidule, atatu-ntchito yotsimikizira za thumba la sefa ya fumbi ndi yofunika kwambiri kuwonetsetsa kuti makina ochotsa fumbi akugwira ntchito bwino ndikuwonjezera moyo wake wautumiki. Posankha thumba la sefa ya fumbi, thumba la fyuluta lomwe lili ndi maumboni atatu-ziyenera kusankhidwa molingana ndi malo enieni ogwiritsira ntchito kuti zitsimikizire kukhazikika ndi kuyendetsa bwino kwa njira yochotsera fumbi.
