Ukulawula Okuqukethwe Komswakama We-Steam ukuze Kuthuthukiswe Ukuzinza Kwenqubo Ekukhiqizeni Okuphakelayo
Isitimu esigcwele sisetshenziswa kabanzi kuzo zombili izinqubo zokushisisa eziqondile nezingaqondile kuzo zonke izimboni ezahlukahlukene. Ngenxa yalokho,ikhwalithi yesitimu idlala indima ebalulekile ekunqumeni ukuzinza kwenqubo kanye nekhwalithi yokugcina yomkhiqizo. Ekwenziweni kokuphakelayo, lapho ukulawulwa komswakama kuthinta ngokuqondile isivuno, ikhwalithi ye-pellet, nokuphepha kokusebenza, ukulawula okuqukethwe komswakama wesitimu sekuyisihloko esibaluleke kakhulu.
I-Ghana, Afrika - I-Henan Mufeng Intelligent Equipment Co., Ltd. iqedele ngempumelelo ukufakwa kanye nokusebenza komugqa wokukhiqiza we-feed fish extrusion engu-500 kg/h kanye nolayini wokukhiqiza we-pellet feed we-2 t\/h eGhana. Lo msebenzi uphawula elinye igxathu elibalulekile ekwandeni kwe-Mufeng emakethe yokucubungula ukudla kwase-Afrika.
Kodwa-ke, umusi uthwala ngokungenakugwenywa umswakama, ongadala izinselelo eziningi ngesikhathi sokukhiqiza. Ngokombono wezokuphepha, umswakama owedlulele wandisa ingozi yesando samanzi nokulimala kwamapayipi. Ngokombono wenqubo, umswakama we-steam ongazinzile uthinta ngqo ukusebenza kahle kokushisa kanye nokuvumelana komkhiqizo.
Kuizinqubo zokushisa eziqondileIsitimu sekhwalithi ephezulu kufanele sihlangabezane nezidingo eziyisisekelo ezilandelayo: izinga lokugeleza elizinzile nelanele, ukucindezela okungaguquki nezinga lokushisa, ukungabikho komoya noma amanye amagesi angajikijeki, umswakama ophansi futhi ozinzile, kanye nokungcola okuncane. Uma lezi zimo zihlangatshezwana nazo, izinqubo zokukhiqiza zingasebenza ngokuphepha nangokuqhubekayo, ziqinisekise ikhwalithi yomkhiqizo engaguquki.
Kuizinqubo zokushisa ezingaqondile, umswakama othwala umusi uholela ekudlulisweni kokushisa okungazinzile. Lokhu kungazinzi kubangela ukushintshashintsha kwezinga lokushisa kwesitolo, kuthinte kabi ukulawulwa kwenqubo futhi kubangele ikhwalithi yomkhiqizo engahambisani.
Ekukhiqizeni ukudla,okuqukethwe komswakama kungenye yemingcele yekhwalithi ebaluleke kakhulu. Umswakama ophansi wehlisa isivuno sokudla futhi unomthelela ngqo enzuzweni yezitshalo. Uma amazinga omswakamo ehla kakhulu, okuphakelayo kuba brittle futhi kungase kuphuke, okwenza ukukhiqizwa okuvamile kungenzeki. Ngakolunye uhlangothi, umswakama owedlulele ungaholela ekusheleleni kwemishini, izinga eliphansi le-pellet, kanye nengozi eyengeziwe yokukhula kwesikhunta ngesikhathi sokugcinwa.
Umswakama wokugcina wemikhiqizo yokuphakelayo unqunywa izici ezintathu eziyinhloko: umswakama wokuqala wezinto zokusetshenziswa ezingenayo, inani lamanzi elengezwe ngesikhathi sokucubungula, kanye nenani lomswakamo elikhishwayo ngesikhathi somiswa (uma likhona). Ngenkathi izigayo eziningi zokudla ziqapha eduze umswakama wempahla eluhlaza kanye nokusebenza kahle kokomisa,ukuguquguquka okukodwa okuyisihluthulelo kuvame ukunganakwa—umswakama womoya ngokwawo.
I-Steam yethula kokubili ukushisa nomswakama enqubeni. Ngesikhathi sokulungiswa, umswakama we-steam uxubana nezinto zokudla futhi ukhuthaze i-gelatinization yesitashi. Uma umswakama wesitimu ushintshashintsha kakhulu—ikakhulukazi uma uphezulu kakhulu—ungaholela kalula emazingeni omswakama womkhiqizo angazinzile. Lolu daba luletha inselele enkulu yokukhiqiza okunciphile kanye nokulawulwa kwenqubo okunembayo ezigayweni zesimanjemanje.
Le nkinga ayigcini nje embonini yokudla. Izinselele ezifanayo zikhona kwezinye izinqubo eziningi zezimboni ezithembele kakhulu ekushiseni ngesitimu. Ukuze ulawule ngempumelelo umswakama we-steam, kubalulekile ukuqonda kuqala imithombo yawo eyinhloko. Umswakama we-steam ngokuyinhloko uvela ezindaweni ezimbili: umswakama owedlulele ngesikhathi sokukhiqiza isitimu esibhayela kanye nomswakama owakheka ngenxa yokufiphala ngesikhathi sokuthutha isitimu.
Ukunciphisa i-boiler carryover kanye nokwenza ngcono ukushiswa kokushisa kwamapayipi esitimu kungasiza ukunciphisa ukukhiqizwa komswakama. Nokho, ngaphansi kwezimo zamanje zobuchwepheshe, lezi zinyathelo zizodwa zingakwazi kuphelanciphisaamazinga omswakamo—awakwazi ukuzinza ngokugcwele noma ukulawula ngokunembile umswakama womusi. Ngakho-ke, izixazululo ezengeziwe zobuchwepheshe ziyadingeka.
Izinyathelo ezisebenzayo zibandakanya ukuthuthwa kwamanzi ngendlela efanele nokuklanywe kahle kwamapayipi nemishini yesitimu, kanye nokusetshenziswaizihlukanisi zamanzi omusiezinqubweni ezinezidingo zekhwalithi ephezulu yesitimu. Kwezinye izinhlelo zokusebenza ezibucayi, ezifana nokukhiqizwa kukagwayi, amasistimu abanzi okulawula umswakama wesitimu asetshenziswa ukuze kugcinwe umswakama wesitimu kumazinga aphansi kakhulu futhi azinzile.
Kubalulekile futhi ukuqaphela ukuthi okuqukethwe komswakamo wesitimu kushintshashintsha ngokuqhubekayo ngokushintsha kwezinga lokushisa, umthwalo wesitimu, nezinga lekhono lomsebenzisi. Ngenxa yalokho,isilinganiso esinembile sokuqukethwe komswakama wesitimu, kuhlanganiswe nokwenza kahle okunengqondo kwamapharamitha wenqubo, kubalulekile ukuze kuzuzwe ikhwalithi yomkhiqizo engaguquki futhi ezinzile.
, isitimu sihlangana ngokuqondile noma ngokungaqondile nomkhiqizo. Umswakama owuketshezi othwelwe isitimu ungabangela ukushintshashintsha kokuqukethwe komswakamo womkhiqizo, okuvame ukubonwa ezinqubweni zokulungisa ukudla kanye nezimboni ezifana nokukhiqizwa kukagwayi. Lokhu kuguquguquka kunciphisa ukulawuleka kwenqubo futhi kwenza kube nzima ukugcina ukucaciswa komkhiqizo okungaguquki.
