Hydraulic Slewing Working Principle
Ts'ebetso ea mohato ka mohato
Sistimi ea ho Slewing ea Hydrauliclatela tatellano e nepahetseng ho fihlela ho potoloha ha bonolo le ho laoloa. Ts'ebetso e qala ha opareitara e kenya lever ea taolo. Ketso ena e romela mokelikeli oa hydraulic o hatelletsoeng ho tloha pompong ka li-valve tsa taolo le li-hoses ho koloi ea hydraulic. Enjene e amohela matla ana 'me e qala ho potoloha, e fetola bethe le mochini o khomaretsoeng.
Hangata baenjiniere ba fetola valve ea ho laola matla hore e be boemong bo sa nke lehlakore pele ba lekanya likhatello tsa ho kena le ho tsoa. Ka mor'a moo ba bala matla a ho kenya le ho hlahisa, hammoho le katleho ea tsamaiso. Ka ho koala butle-butle koung ea drain ka mehato e nyane, ba bona kamoo boemo ba valve bo amang phetiso ea matla. Mokhoa ona o bonts'a karolo ea valve joalo ka clutch, e lumellang taolo e hlophisitsoeng hantle nakong ea ts'ebetso ea ho bolaea. Litsamaisong tse ling tse tsoetseng pele, tatellano e kenyelletsa ho sekaseka bohlokoa ba karolo le ho ntlafatsa tlhokomelo ho netefatsa ho ts'epahala. Mohato o mong le o mong, ho tloha ho matla a ho kenya letsoho ho kenya letsoho, o kenya letsoho ts'ebetsong e tsitsitseng le e sebetsang ea mekhoa ea Hydraulic Slewing.
Phetiso ea Matla le Phetoho
Sistimi ea ho Slewing ea Hydraulice ipabola ho fetoleng matla a haeteroliki ho a potoloha ka mochini. Pompo ea hydraulic e fana ka oli e hatelitsoeng ho enjene, ebe e fetola matla ana torque. Sebaka sa ho bolaea se tsamaisa torque ena, e lumellang mochine hore o potolohe tlas'a meroalo e boima. Ho sebetsa hantle ha ts'ebetso ena ho itšetlehile ka lintlha tse 'maloa, tse kang khatello ea accumulator le molumo.
Keletso:Ho eketsa khatello ea pele ea accumulator kapa bophahamo ba modumo ho ka fokotsa tlhokeho ya matla a phahameng le ho fokotsa tshebediso ya matla nakong ya ho bolaya.
Tafole e ka tlase e totobatsa kamoo liparamente tse fapaneng li amang matla le ts'ebeliso ea matla lits'ebetsong tsa slewing:
| Paramethara | Boemo/Boleng | Phello ho Slewing Motor Power le Energy Consumption |
|---|---|---|
| Accumulator Khatello ea Pele | E phahameng | Matla a phahameng a fokotseha, tšebeliso ea matla e ea fokotseha |
| Accumulator Bolumo | 350–500 L | Molumo o moholo o fokotsa matla a holimo le tšebeliso ea matla |
| Hybrid vs Sistimi e Hloekileng ea Motlakase | Sistimi ea Hybrid | Tšebeliso e phahameng ea matla le matla e fokotsehile ka 29.6% |
| Hoisting Motor Peak Power | Motlakase o hloekileng: 600 kW | Hybrid: 380 kW (phokotso ea 36.7%) |
| Tšebeliso ea Matla ka Cycle | Motlakase o hloekileng: 4332 kJ | Hybrid: 3048 kJ (29.6% ea ho boloka matla) |
Sistimi ea Hybrid e tsoela pele ho ntlafatsa ts'ebetso ka ho khutlisa matla nakong ea ho fokotseha le ho e sebelisa hape nakong ea ho potlakisa. Mokhoa ona o fokotsa litlhoko tsa matla a holimo le tšebeliso ea matla ka kakaretso, e leng se etsang hore litsamaiso tsa Hydraulic Slewing li sebetse hantle haholo bakeng sa lits'ebetso tse boima.
Taolo le Nepahetseng
Sistimi ea sejoale-joale ea Hydraulic Slewing e fana ka taolo e ikhethang le ho nepahala. Litharollo tsa taolo ea bobeli li etsa hore ho be le ho nepahala ho phahameng le karabelo e matla, leha e le lisebelisoa tse kholo joalo ka li-crane tse tsamaeang tse nang le mehele e hlabang ho fihla ho limithara tse 50 ka bophara. Litsamaiso tsena li boloka ts'epahalo le matla a matla ha li ntse li kopana le litekanyetso tse nepahetseng tse nepahetseng.
Mekhoa e tsoetseng pele ea ho laola, joalo ka PID e sa tsitsang le neural network model predictive control, e ntlafalitse haholo ho nepahala ha maemo. Ka mohlala, mekhoa e meng e fokolitse liphoso tsa boemo ho tloha ho 62 mm ho ea ho 10 mm. Lintlafatso tsena li boetse li lebisa polokong ea matla, ka phokotso ea ho fihla ho 15.35% tlasa maemo a ho se be le moroalo.
Li-bearings tse phahameng tse nepahetseng li bapala karolo ea bohlokoa ho boloka ho nepahala. Baetsi ba sebelisa meralo e khethehileng ea mabelo le lisebelisoa tse matla haholo ho netefatsa ts'ebetso e tsitsitseng, esita le tlas'a meroalo e boima le maemo a feteletseng. Motsoako ona oa litsamaiso tse tsoetseng pele le likarolo tse matla li lumella litsamaiso tsa Hydraulic Slewing ho fihlela motsamao o bonolo, o nepahetseng oa bohlokoa bakeng sa mesebetsi e boima ea indasteri.
Melemo le Lisebelisoa tsa Hydraulic Slewing
Melemo ea Bohlokoa
Hydraulic Slewinge fana ka melemo e 'maloa ea bohlokoa bakeng sa mechine e boima. Sistimi e fana ka ho potoloha ho boreleli le ho laoloa, e thusang basebelisi ho beha lisebelisoa ka nepo e phahameng. Sistimi ea Hydraulic Slewing e sebetsana le meroalo e meholo habonolo. Li fana ka torque e matla, e etsang hore e be tse loketseng bakeng sa mesebetsi e boima. Theknoloji e boetse e ntlafatsa polokeho ka ho lumella motsamao o nepahetseng, esita le libakeng tse thata.
Baenjiniere ba bangata ba ananela ho tšepahala ha Hydraulic Slewing. Sistimi e sebetsa hantle maemong a thata, joalo ka libaka tsa kaho kapa liforomo tsa kantle ho naha. Litlhoko tsa tlhokomelo li lula li le tlaase hobane likaroloana li hanela ho senyeha le ho senyeha. Basebelisi ba ka tšepa hore sistimi e tla sebetsa ka nako e telele.
Hlokomela:Lits'ebetso tsa Hydraulic Slewing hangata li fokotsa tšebeliso ea matla le litšenyehelo tsa ts'ebetso. Sena se thusa lik'hamphani ho boloka chelete le ho sireletsa tikoloho.
