Lingakanani iqondo lobushushu elifuna ukufudunyezwa?
Lingakanani iqondo lobushushu elifuna ukufudunyezwa?
Yintoni iqondo lokushisa elicetyiswayo lokuthwala ngexesha lokuhlanganisana okushushu? Liphakame kangakanani iqondo eliphezulu? Ngaba kulungile kwi-160 degrees ukuya kwi-180 degrees?
Iqondo lokushisa lokufudumeza kufuneka limiselwe ngokuhambelana nobushushu bendawo yendibano, izinto ezithwalayo, i-diameter efanelekileyo, ukuphazamiseka kunye nokukhutshwa okuncinci kwi-hot fitting. T=T0+T=T0+(δ+Δ)/(α+d)
Phakathi kwabo T ── ubushushu bokufudumala, °C;
T0── iqondo lobushushu bendibano, °C;
δ── Uphazamiseko lolungelelwaniso, mm;
Δ── Ubuncinci bokukhutshwa kwendibano, mm;
α──I-coefficient yokwandiswa komgca wesixhobo;
d── Idayamitha yokufaka, mm.
Xa ufudumeza i-bearing, iqondo lokushisa akufanele lidlule kwi-80 ° C.
Ubushushu obuqhelekileyo bokuthwala ukufudumeza ngu 80°C~100°C.
Xa i-diameter yangaphakathi ye-bearing inkulu kune-70mm, okanye ukungenelela okufanelekileyo kukhulu, indlela yokufudumala isetyenziselwa ukwandisa umngxuma ongaphakathi we-bearing kwaye ushushu umkhono. Ngokuqhelekileyo, ukuthwala kushushu ukuya kuma-80°C, ukuya kuthi ga kwi-100°C. Ukugqithisa i-120 ° C kuya kubangela ukufudumala kwesigxina, okuya kunciphisa ubunzima kunye nokuchaneka kwendandatho yokuthwala kunye nokuchaphazela ubomi benkonzo yokuthwala.
Ubushushu bokufudumala bunokubalwa kwaye bunqunywe ngokuhambelana nobushushu bendawo yendibano, izinto zokuthwala, ububanzi bokulungelelana, ubungakanani bokuphazamiseka, kunye nokukhutshwa okuncinci kokufakwa okushushu.
