Sena se fokotsa ho feto-fetoha ha linako tsa ho bula/ho koala, e leng sa bohlokoa bakeng sa lits'ebetso tse hlokang ts'ebetso e ka phetoang (mohlala, lipompo tsa infusion tsa bongaka).
Ntlafatso ea Potoloho ea Magnetic
Ho ntlafatsa lekhalo la moea pakeng tsa karolo e ka hare le ea armature ho fokotsa khanyetso ea makenete. Mohlala, moralo oa phallo ea axial li-valve tsa letoto la 188 tsa ASCO o tsepamisa matla a makenete, o fokotsa tahlehelo ea matla le ho ntlafatsa lebelo la karabelo. Li-simulation tsa matla a mokelikeli oa lik'homphieutha (CFD) li ntlafatsa meralo ena haholo ho felisa ho lutla ha phallo.
3. Ntlafatso ea Sistimi ea Motlakase le Taolo
Phetoho ea Bophara ba Pulse (PWM) ka Taolo e Ikamahanyang le Maemo
Theknoloji ea PWM e fetola potoloho ea mosebetsi oa motlakase o khannang ho leka-lekanya tšebeliso ea matla le nako ea karabelo. Phuputso e bontšitse hore ho eketsa maqhubu a PWM ho tloha ho 50 Hz ho ea ho 200 Hz ho fokolitse nako ea karabelo ka 21.2% lits'ebetsong tsa ho fafatsa tsa temo. Li-algorithms tse ikamahanyang le maemo, joalo ka ho sefa Kalman, li ka ntlafatsa liparamente tse kang motlakase (10-14 V) le nako ea ho lieha (15-65 ms) bakeng sa melemo ea ts'ebetso ea nako ea sebele.
Ho Qalisoa ha Motlakase o Phahameng
Ho sebelisa motlakase o matla (mohlala, 12 V ho fapana le 9 V e lekantsoeng) nakong ea ts'ebetso ho hotetsa karolo ea mantlha ka potlako, ho hlōla khohlano e sa fetoheng. Mokhoa ona, o sebelisoang li-valve tsa indasteri tsa Staiger, o fihlella linako tsa karabelo tsa boemo ba 1 ms bakeng sa lits'ebetso tsa inkjet ea lebelo le phahameng.
Maikutlo a Hona Joale le Pholoso ea Matla
Ho kenya tshebetsong di-loop tsa karabelo tse utlwang motlakase ho netefatsa tshebetso e tsitsitseng ka ho lefella diphetoho tsa motlakase. Ho feta moo, ho brake e ntjhafatsang motlakase ho hapa matla nakong ya ho tima tshebetso, ho fokotsa tshebediso ya matla ka 30% ha ka nako e le nngwe ho boloka karabelo e potlakileng.
4. Lintho tse lokelang ho nahanoa ka tikoloho le ts'ebetso
Puseletso ea Mocheso
Mocheso o feteletseng o ama thepa ea thepa. Mohlala, mocheso o tlase o eketsa viscosity metsing, o liehisa motsamao oa li-valve. Li-valve tsa sehlopha sa lifofane, joalo ka tse ntlafalitsoeng ke China Aerospace Science and Technology Corporation, li sebelisa insulation ea mocheso e nang le sekheo sa moea le li-lubricant tsa mocheso o tlase ho boloka linako tsa karabelo tse ka tlase ho 10 ms esita le ho -60°C.
Ntlafatso ea Matla a Mokelikeli
Ho fokotsa moferefere oa mokelikeli ka likou tsa li-valve tse otlolohileng le meralo ea ho hanyetsa phallo e tlase ho fokotsa khatello ea mokokotlo. Lisebelisoa tsa bongaka, sena se lumella taolo e nepahetseng ea maro a nang le viscosity e tlase (mohlala, meriana) ka tieho e fokolang.
Ho Fokotsa Litšila le Tšilafalo
Ho kopanya difilthara tse kahare (mohlala, letlooeng la 40-μm) ho thibela ho bokellana ha dikarolwana, e leng se ka sitisang armature. Tlhokomelo ya kamehla, jwalo ka ho hlwekisa ka ultrasound, e netefatsa tshebetso e tsitsitseng dibakeng tse thata.
