Tshebedisano e hlahisitsweng ha e a fana feela ka dikarolo tse fihlelang ditlhoko tse thata tsa BMW tsa GS 90018-2. maemo a tloaelehileng empa e thehile tekanyetso e ncha bakeng sa tlhahiso ea ho nepahala e bolokang litšenyehelo lefapheng la likoloi.

 

The Technical Crucible: Maemo a sa Sekisetseng a BMW

Li-valve tsa solenoid tsa khabone li na le boemo ba bohlokoa lits'ebetsong tsa sejoale-joale tsa ho ntša mosi oa likoloi. Ha likhatello tsa taolo li ntse li eketseha lefatšeng ka bophara, likarolo tsena li fetohile ho tloha likarolong tse bonolo tsa mechini ho ea lits'ebetsong tse entsoeng ka nepo tse hlokang ts'epo e ikhethang.

Saense ea Lintho tse bonahalang e le Ntlafatso ea Litšenyehelo

Mekhoa ea setso ea ho fihlela litlhaloso tse joalo tse hlokang tlhokomelo hangata e kenyelletsa thepa ea boleng bo holimo le meeli ea moralo o bolokang litšenyehelo. Baenjiniere ba Ansix Tech ho e-na le hoo ba ile ba atamela phephetso ena ka ho etsa thepa ea maano. Phuputso ea k'hamphani e fumane hore motsoako o fetotsoeng oa polyphenylene sulfide (PPS), o matlafalitsoeng ka litaba tsa khalase tse leka-lekaneng hantle le li-additives tse ikhethileng, o ka fihlela litlhoko tsa BMW tsa ho hanyetsa mocheso le lik'hemik'hale ka litšenyehelo tse ka bang 22% tsa thepa ho feta polymer e boletsoeng qalong.

 

"Khetho ea thepa e emela monyetla oa pele le o nang le tšusumetso e kholo oa ho ntlafatsa litšenyehelo ho enteng," ho hlalosa Ngaka Lena Schmidt, Hlooho ea Boenjiniere ba Thepa ea Ansix Tech. "Ka ho sebelisana haufi-ufi le bafani ba resin le ho etsa liteko tse potlakileng tsa botsofali, re hlahisitse motsoako o fanang ka mocheso o hlokahalang oa tšebeletso o tsoelang pele oa 150°C ha o ntse o ntlafatsa litšobotsi tsa phallo bakeng sa ho enteng ka katleho."

 

Boqapi ba thepa bo ile ba atoloha ka nqane ho kgetho ya motheo ya polymer. Sebopeho sa Ansix Tech se kenyeleditse dikahare tsa PPS tse sebedisitsweng maemong a ileng a boloka ditlhaloso tsa tshebetso ha ka nako e ts'oanang a fokotsa ditjeo tsa thepa e tala. Ka diteko tse hlokolosi, baenjiniere ba thehile hore dikahare tse sebedisitsweng hape tse fihlang ho 15% di ka kopanngwa ntle le ho beha tshebetso ya bohlokwa ya valve e thibelang ho dutla kapa ho tshwarella nako e telele, e leng se hlahisang melemo ya moruo le ya tikoloho.

 

Litšobotsi tse ntlafetseng tsa phallo ea motsoako li fane ka melemo e eketsehileng ea tlhahiso.

Ka ho beha leihlo diprofaele tsa kgatello le ho kenya tshebetsong taolo e kwalletsweng ya ntlha ya phetoho ya V/P—phetoho ya bohlokwa ho tloha mohatong wa ente ho ya mohatong wa ho paka—Ansix Tech e fihletse botsitso bo sa lebellwang ka karolo ya boima le boholo.

 

"Kamano pakeng tsa kgatello, bophahamo bo itseng, le mocheso di laola boleng ba karolo ya ho qetela ho enteng," ho bolela Michael Chen, Motsamaisi wa Boenjiniere ba Tshebetso wa Ansix Tech. "Ka ho theha diprofaele tse ntle tsa kgatello le ho kenya tshebetsong taolo e ikamahanyang le maemo ho di boloka, re fokoditse phapang ya karolo ho karolo ka 68% ha ka nako e le nngwe re ntse re ntlafatsa nako ya potoloho."
