Okokuqala, lezi zinhlobo ezimbili zamajekhi zingamajekhi ethu ajwayelekile, futhi ukusetshenziswa kwazo kubanzi kakhulu.Uyini umehluko?Ake sichaze kafushane:
Ake sikhulume ngeisikulufuibhodlelaujekeokokuqala, esebenzisa ukunyakaza okuhlobene kwesikulufu kanye nenadi ukuphakamisa noma ukwehlisa into esindayo.Iqukethe ifreyimu eyinhloko, isisekelo, induku yesikulufu, umkhono ophakamisayo, iqembu le-ratchet nezinye izingxenye eziyinhloko.Lapho usebenza, kuyadingeka kuphela ukuphinda uphendule isibambo ngesikrufu se-ratchet, futhi igiya le-bevel elincane lizoshayela igiya elikhulu le-bevel ukuze lijikeleze, kwenze isikulufu sijikeleze.Isenzo sokuphakamisa noma ukwehlisa umkhiqizo womkhono ophakamisayo.Njengamanje, lolu hlobo lukajeke lunobude obuyi-130mm-400mm.Uma iqhathaniswa nejekhi ye-hydraulic, inokuphakama okuphezulu kokuphakamisa, kodwa ukusebenza kahle kuphansi, ku-30% -40%.
Okulandelayo yi-i-hydraulicibhodlelaujeke, ehambisa amandla ngamafutha okucindezela (noma amafutha asebenzayo), ukuze i-piston iqedele isenzo sokuphakamisa noma sokwehlisa.
1. inqubo yokumunca iphampu
Lapho isibambo se-lever 1 siphakanyiswa ngesandla, i-piston encane ishayelwa phezulu, futhi ivolumu yokusebenza yokuvala emzimbeni wepompo 2 iyanda.Ngalesi sikhathi, njengoba i-valve yokuhlola ukukhishwa kwamafutha kanye ne-valve yokukhipha uwoyela ngokulandelanayo ivala izindlela zikawoyela lapho zitholakala khona, ivolumu yokusebenza emzimbeni wephampu 2 iyanda ukuze yakhe i-vacuum eyingxenye.Ngaphansi kwesenzo sokucindezela komkhathi, uwoyela ethangini likawoyela uvula ivalvu yokuhlola ukumunca uwoyela ngepayipi likawoyela bese ugeleza ungene emzimbeni wepompo 2 ukuze uqedele isenzo sokumunca uwoyela.
2. Amafutha okumpompa kanye nenqubo yokuphakamisa esindayo
Lapho isibambo se-lever l sicindezelwa phansi, i-piston encane iqhutshelwa phansi, umthamo wokusebenza wegumbi elincane lamafutha emzimbeni wepompo 2 uyancishiswa, amafutha akuwo acindezelwa, futhi i-valve yokuhlola ukukhishwa kwamafutha iphushwa ivuleke ( ngalesi sikhathi, ukumunca uwoyela ngendlela eyodwa Valve ivala ngokuzenzakalelayo umjikelezo kawoyela ethangini likawoyela), bese uwoyela ungenai-hydraulicisilinda (igumbi lamafutha) ngepayipi likawoyela.Njengoba i-hydraulic cylinder (i-oil chamber) nayo iyivolumu yokusebenza evaliwe, uwoyela ongenayo uyacindezelwa ngenxa Amandla akhiqizwa ukucindezela azophusha i-piston enkulu futhi aqhube isisindo phezulu ukuze enze umsebenzi.Ukuphakamisa nokucindezela ngokuphindaphindiwe isibambo se-lever kungenza into esindayo ikhuphuke ngokuqhubekayo futhi kufinyelele injongo yokuphakamisa.
3. inqubo yokuwa kwento esindayo
Lapho i-piston enkulu idinga ukubuyela phansi, vula i-valve yokukhipha uwoyela engu-8 (zungeza ngo-90°), bese ngaphansi kwesenzo sesisindo sento esindayo, uwoyela ku-hydraulic cylinder (igumbi lamafutha) ageleza abuyele ethangini likawoyela, futhi i-piston enkulu yehlela endaweni.
Ngokusebenzisa inqubo yokusebenza ye-ibhodlelaujeke, singaphetha ngokuthi isimiso sokusebenza sokudluliselwa kwe-hydraulic yilo: ukusebenzisa amafutha njengendlela yokusebenza, ukunyakaza kudluliselwa ngokushintshwa kwevolumu yokuvala, futhi amandla adluliselwa ngokucindezela kwangaphakathi kwamafutha.I-hydraulic transmission iyithuluzi lokuguqula amandla.
