2. Iimpawu zobunjineli kwiindawo ezishushu kakhulu
•Uyilo oluNciphisiweyo lweBonnet RadiatingSusa igumbi lokupakisha isiqu kude neendawo zomzimba ezinobushushu obuphezulu. Iifin zokupholisa ezishushu ezakhelwe ngaphakathi zikhusela izixhobo zokupakisha isiqu (i-graphite/V-ring eguquguqukayo) kunye nee-actuators ezenziwe ngesandla/ezenzekelayo kubushushu bepayipi ekhazimlayo, ziqinisekisa ubomi benkonzo ende.
•Iiseti zokupakisha zaseBelleville ezilayishwe bukhomaUkwanda kunye nokucutheka kobushushu kunokubangela ukuphumla kokupakisha.

5. Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo Ngobunjineli)
Q1: Ingakanani iqondo lobushushu lokusebenza eliphezulu kwiivalvu zebhola ezihleli phantsi zePPL xa kuthelekiswa neevalvu zebhola ezihleli phantsi zesinyithi?
Izitulo zePPL (Polyparaphenylene) zisebenza ngokuthembekileyo ukuya kuthi ga kwi-280°C–300°C (536°F–572°F) kwizinto ezicocekileyo kunye nomphunga. Iivalvu zebhola ezifakwe ngesinyithi ezine-HVOF hardfacing (Tungsten Carbide, Chrome Carbide, okanye Stellite) zenzelwe iinkonzo ezigqithisileyo ukuya kuthi ga kwi-550°C–650°C (1022°F–1202°F) kunye ne-abrasive media.
Umbuzo 2: Kutheni kufuneka ibhonethi ende kwiivalvu zebhola ezishushu kakhulu?
Ibhonethi ende isusa ibhokisi yokupakisha isiqu kude nomzimba wombhobho oshushu, isusa ubushushu obukhanyayo. Oku kugcina izitywino zesiqu (ezifana negrafiti eguquguqukayo) zikwinqanaba lobushushu obusebenzayo obukhuselekileyo, kuthintela ukuwohloka kobushushu, kwaye kukhusela ii-actuators zombane okanye ze-pneumatic ekutshiseni kakhulu.
Umbuzo 3: Ukuthintela njani ukutshixa/ukugabha ibhola xa amaqondo obushushu aphezulu?
Ukwandiswa kobushushu kulawulwa ngokukhetha ngokuchanekileyo izinto ezahlukeneyo (ukulinganisa ii-coefficients zokwandiswa kobushushu bomzimba, ibhola, kunye nesiqu) kunye nokufaka iziniki-mandla zentwasahlobo ezigcweleyo eziphilayo emva kweeringi zesihlalo. Ezi springs ziyacinezelwa ukuze zifunxe ukwanda kobushushu obuphezulu ngaphandle kokunyusa i-torque yokusebenza okanye ukubangela ukubopha koomatshini.
