Ho na le mefuta e mengata ea oli ea hydraulic 'marakeng, hape ho na le mefuta e mengata ea mochini oa hydraulic.Leha mesebetsi ea oli ea hydraulic e ts'oana, ho ntse ho hlokahala ho khetha oli e fapaneng ea hydraulic bakeng sa mechini e fapaneng ea hydraulic.Ha u khetha oli ea hydraulic, basebetsi ba lokela ho utloisisa hore na ba kōptjoa ho etsa eng, ebe ba khetha oli e nepahetseng ea hydraulic bakeng sa mochini oa hydraulic.
Mokhoa oa ho khetha oli e nepahetseng ea Hydraulic bakeng sa Hydraulic Press
Ho sebelisoa mekhoa e 'meli ha ho khethoa oli ea hydraulic.E 'ngoe ke ho khetha oli ea hydraulic ho latela mefuta ea oli le litlhaloso tse khothaletsoang ke lisampole kapa litaelo tsa moetsi oa mochini oa hydraulic.E 'ngoe ke ho nahana ka botlalo ho khethoa ha oli ea hydraulic ho latela maemo a khethehileng a mochini oa hydraulic, joalo ka khatello ea ho sebetsa, mocheso o sebetsang, lebelo la ho sisinyeha, mofuta oa likarolo tsa hydraulic le lintlha tse ling.
Ha u khetha, mesebetsi e ka sehloohong e lokelang ho etsoa ke: ho khetholla mefuta e mengata ea viscosity ea oli ea hydraulic, ho khetha mefuta e nepahetseng ea oli ea hydraulic, le ho finyella litlhoko tse khethehileng tsa tsamaiso ea hydraulic.
Hangata e khethoa ho latela likarolo tse latelang:
(1) Ho latela likhetho tse fapaneng tsa mochini o sebetsang oa hydraulic press
Mechini e nepahetseng le mechini e akaretsang e na le litlhoko tse fapaneng tsa viscosity.Bakeng sa ho qoba deformation ea likarolo tsa mochini tse bakoang ke ho phahama ha mocheso le ho ama ho nepahala ha ts'ebetso, mochini o nepahetseng o lokela ho sebelisa oli ea hydraulic e nang le viscosity e tlase.
(2) Khetha ho latela mofuta oa pompo ea hydraulic
Pompo ea hydraulic ke karolo ea bohlokoa ea mochine oa khatiso oa hydraulic.Ka mochine oa khatiso oa hydraulic, lebelo la eona la ho tsamaea, khatello le ho phahama ha mocheso li phahame, 'me nako ea eona ea ho sebetsa e telele, kahoo litlhoko tsa viscosity li thata.Kahoo pompo ea hydraulic e lokela ho nahanoa ha u khetha viscosity.
(3) Khetha ho ea ka khatello ea ho sebetsa ea mochine oa khatiso oa hydraulic
Ha khatello e phahame, oli e nang le viscosity e phahameng e lokela ho sebelisoa ho qoba ho lutla ho feteletseng ha sistimi le ts'ebetso e tlase.Ha khatello ea ho sebetsa e le tlaase, ho molemo ho sebelisa oli e nang le viscosity e tlaase, e ka fokotsang tahlehelo ea khatello.
(4) Nahana ka mocheso oa tikoloho ea ho sebetsa oa mochine oa khatiso oa hydraulic
The viscosity ea oli ea diminerale e fetoha haholo ka lebaka la tšusumetso ea mocheso.E le ho etsa bonnete ba hore ho na le viscosity e loketseng haholoanyane mocheso oa ho sebetsa, tšusumetso ea mocheso oa tikoloho e potolohileng e tlameha ho nkoa hape.
(5) Nahana ka lebelo la ho sisinyeha ha likarolo tse sebetsang tsa mochine oa khatiso oa hydraulic
Ha lebelo le tsamaeang la likarolo tse sebetsang tsamaisong ea hydraulic le phahame haholo, lebelo la ho phalla ha oli le lona le tlaase, tahlehelo ea hydraulic e eketseha ka mokhoa o sa tloaelehang, 'me ho tsoa ho fokotseha ho batla ho fokotseha, kahoo ho molemo ho sebelisa oli e nang le viscosity e tlaase.
(6) Khetha mofuta o nepahetseng oa oli ea hydraulic
Ho khetha oli ea hydraulic ho bahlahisi ba kamehla ho ka fokotsamochini oa khatiso oa hydraulicho hloleha le ho lelefatsa bophelo ba mochini oa khatiso.
