Kwizixhobo zokwenza iphepha, iinkcukacha ze-"Yankee dryers" azichazwa rhoqo "ngeekhilogram". Endaweni yoko, iiparameter ezifana nobubanzi (umz., 1.5m, 2.5m), ubude, uxinzelelo lokusebenza, kunye nobukhulu bezinto zixhaphake kakhulu. Ukuba "3kg" kunye "5kg" apha zibhekisa kuxinzelelo lokusebenza lweYankee dryer (iyunithi: kgf/cm², oko kukuthi, kilogram-force ngesentimitha yesikwere), umahluko wazo ophambili ubonakala kakhulu kwezi zinto zilandelayo:
- Amaqondo obushushu ahlukeneyo okusebenza
Ukufudumeza kweeYankee dryers kudla ngokuxhomekeka kumphunga ogcweleyo ngaphakathi, kwaye uxinzelelo lomphunga lunxulumene ngokuthe ngqo nobushushu (kulandela ijika elibonisa umphunga):
Ubushushu bomphunga ogcweleyo kwi-3kgf/cm² (malunga ne-0.3MPa) bumalunga ne-133℃;
Ubushushu bomphunga ogcweleyo kwi-5kgf/cm² (malunga ne-0.5MPa) bumalunga ne-151℃.
Umahluko kubushushu buchaphazela ngokuthe ngqo ukusebenza kakuhle kokomisa kwephepha: okukhona uxinzelelo luphezulu (kwaye ngaloo ndlela ubushushu buphezulu), kokukhona ubushushu bugqithiselwa ephepheni ngexesha ngalinye, nto leyo ebangela isantya sokuma esikhawulezayo. Oku kuyenza ifaneleke kumaphepha afuna ukusebenza kakuhle kokomisa (njengephepha lethishu kunye noomatshini bephepha abakhawulezayo).
- Ukusetyenziswa kwamandla okwahlukileyo kokomisa
Ukusebenza kakuhle kokomisa: Isixhobo sokomisa iYankee esine-5kgf/cm² yoxinzelelo, esinobushushu obuphezulu, sinomahluko omkhulu kubushushu xa sithelekiswa nephepha, nto leyo ekhokelela kwisantya sokudlulisa ubushushu esikhawulezayo. Sinokuphehla umswakama omninzi ngexesha elinye kwaye sizivumelanise nesantya esiphezulu sokusebenza komatshini wephepha.
Ixabiso lokusetyenziswa kwamandla: Umphunga kuxinzelelo lwe-5kgf/cm² ufuna imveliso ephezulu yebhoyila, nto leyo ebangela ukusetyenziswa kwamandla okuphezulu (njengamalahle, igesi yendalo, njl.njl.). Umphunga kuxinzelelo lwe-3kgf/cm² usebenzisa amandla aphantsi, nto leyo eyenza ukuba ifaneleke kwiimeko apho isantya sokomisa singabalulekanga khona (njengeemashini zephepha ezinesantya esiphantsi kunye neeklasi zamaphepha amakhulu).
- Iintlobo zePhepha ezifanelekileyo kunye neenkqubo
Isixhobo sokomisa iYankee esingu-3kgf/cm²: Ngobushushu obuphantsi, sifanelekile kwiintlobo zamaphepha ezibuthathaka kubushushu (ezifana namaphepha athile afakwe iwax, amaphepha aneengubo ezitshintsha ubushushu) okanye amaphepha atyebileyo afuna ukoma kancinci ukuze kuthintelwe ukugoba nokuqhekeka (ezifana nephepha lephepha, iphepha lekrafti elityebileyo).
Isixhobo sokomisa iYankee esingu-5kgf/cm²: Xa sinobushushu obuphezulu, sifanelekela iphepha lethishu (njengephepha leendaba, iphepha lokubhala), amaphepha enkcubeko eveliswa ngesantya esiphezulu, njl. Ingasusa umswakama ngokukhawuleza, iqinisekise ukusebenza kakuhle komatshini wephepha, kwaye inciphise umngcipheko wokuqhekeka kwephepha ngokunciphisa ixesha lokuhlala kwephepha kwinkqubo yokomisa.
- Iimfuno ezahlukeneyo zezixhobo kunye nokhuseleko
Nangona zombini uxinzelelo lwe-3kgf/cm² kunye ne-5kgf/cm² zizezemikhumbi enoxinzelelo oluphantsi (ngesiqhelo, uxinzelelo loyilo lomshini wokomisa weYankee luphezulu kunoxinzelelo olusebenzayo olunomda wokhuseleko), uxinzelelo oluphezulu luthetha iimfuno eziphezulu kancinci zokuqina kwezinto, ukusebenza kokutywina, kunye nobukhulu bodonga lomatshini wokomisa weYankee:
Izinto zesilinda ze-Yankee dryer enoxinzelelo lwe-5kgf/cm² (ezifana nesinyithi esityhidiweyo, isinyithi esityhidiweyo se-alloy) kufuneka ziqinisekise uzinzo phantsi koxinzelelo oluphezulu. Ukuchaneka kokucubungula kwe-welding seams, i-flange seals, kunye nezinye iindawo kungqongqo ngakumbi ukuze kuthintelwe ukuvuza komphunga.
Zombini kufuneka zithobele imithetho yokhuseleko lwezitya zoxinzelelo, kodwa i-Yankee dryer enoxinzelelo lwe-5kgf/cm² isenokuba nokuhlolwa rhoqo nokungqongqo (njengovavanyo lwe-hydrostatic).
Isishwankathelo
IiYankee dryers ezisebenzisa uxinzelelo lwe-3kgf/cm² kunye ne-5kgf/cm² ngokusisiseko zilungisa ubushushu kunye nokusebenza kakuhle kokomisa ngokusebenzisa umahluko woxinzelelo lomphunga. Umahluko ophambili ukwisantya sokomisa, iindleko zokusetyenziswa kwamandla, kunye neentlobo zephepha ezifanelekileyo. Ukhetho kufuneka lujongwe ngokupheleleyo ngokusekelwe kwisantya somatshini wephepha, iimpawu zohlobo lwephepha, uhlahlo lwabiwo-mali lokusetyenziswa kwamandla, njl. Uxinzelelo oluphezulu alukho ngcono ngokuyimfuneko; kufuneka luhambelane neemfuno zenkqubo yokuvelisa.
