I-Bi-directional hydraulic locks kunye neevalve zokulinganisa zingasetyenziswa njengamacandelo okutshixa kwiimeko ezithile ukuqinisekisa ukuba isixhobo esisebenzayo asiyi kutyibilika, sigqithise okanye sishukume ngenxa yezizathu zangaphandle ezifana nobunzima baso.
Nangona kunjalo, phantsi kweemeko ezithile zomthwalo wesantya, azinakusetyenziswa ngokutshintshanayo. Makhe sithethe ngezinye zeembono zombhali kwiifom zesakhiwo seemveliso ezimbini.
I-lock ye-hydraulic lock yi-No. Ngokuqhelekileyo isetyenziswe kwiisilinda ze-hydraulic ezithwala imithwalo okanye iisekethe ze-oyile yemoto ukukhusela i-cylinder ye-hydraulic okanye i-motor ukuba ihambe phantsi phantsi kwesenzo sezinto ezinzima. Xa isenzo sifunekayo, i-oyile kufuneka inikezelwe kwenye isekethe, kwaye i-valve yendlela enye kufuneka ivulwe nge-oyile yolawulo lwangaphakathi ukuvumela i-oyile yesekethe ukuba Kuphela xa idityanisiwe inokuthi i-cylinder ye-hydraulic okanye i-motor isebenze.
Ngenxa yesakhiwo somatshini ngokwawo, ngexesha lokuhamba kwe-cylinder ye-hydraulic, ubunzima obufayo bomthwalo buhlala bubangela ukulahlekelwa ngokukhawuleza koxinzelelo kwigumbi eliphambili lokusebenza, okubangela ukuba kubekho i-vacuum. Le meko isoloko isenzeka kwaba matshini balandelayo:
Isilinda esibekwe nkqo kwikholamu emine yoshicilelo lwehydraulic;
Isilinda sokungunda esiphezulu soomatshini bokwenza izitena;
Icylinder yeoli ejiwuzisa emva naphambili kumatshini weglasi;
Swing cylinder koomatshini bokwakha;
i-winch motor ye-hydraulic crane;
Eyona nto ixhaphakileyo isitshixo sehydraulic sisivalu esipakishweyo sokukhangela. Makhe sijonge kwi-cross-section kunye nesicelo esiqhelekileyo.
Xa ubunzima buwela ngobunzima bawo, ukuba icala leoli yokulawula alizaliswanga ngexesha, i-vacuum iya kuveliswa kwicala le-B, ibangela ukuba i-piston yokulawula ihoxise phantsi kwesenzo sentwasahlobo, eya kuvala indlela enye. ivalve, kwaye emva koko uqhubeke nokubonelela nge-oyile, ukwenza igumbi lokusebenza Uxinzelelo luyenyuka kwaye luvule ivalve yendlela enye. Izenzo ezinjalo zokuvula rhoqo kunye nokuvala ziya kubangela ukuba umthwalo uqhubele phambili ngexesha lenkqubo yokuwa, okukhokelela kwimpembelelo enkulu kunye nokungcangcazela. Ngoko ke, ukutshixa kweendlela ezimbini ze-hydraulic ngokuqhelekileyo akukhuthazwa kwisantya esiphezulu kunye neemeko zomthwalo onzima, kodwa zisetyenziswa ngokuqhelekileyo. Ifanelekile kwiilophu ezivaliweyo kunye nexesha elide lokuxhasa kunye nesantya esisezantsi sokuhamba.
Ukongezelela, ukuba ufuna ukucombulula le ngxaki, unokongeza i-valve ye-throttle kwicala lokubuyisela ioli ukulawula isantya sokuwa ukuze izinga lokuhamba kwepompo yeoli likwazi ukuhlangabezana ngokupheleleyo neemfuno zoxinzelelo lweoli yokulawula.
Ivalve echaseneyo, ekwabizwa ngokuba sisitshixo somda wesantya (jonga uMfanekiso 3), sisivalufa esilawulwa ngaphandle kwaye sivuza ngaphakathi. Ibandakanya ivalve yendlela enye kunye nevalve yolandelelwano esetyenziswa kunye. Kwisekethe ye-hydraulic, inokuthintela i-cylinder ye-hydraulic okanye i-motor. Ioyile kwisekethe yeoli ibangela ukuba i-hydraulic cylinder
I-1-end cover; 2, 6, 7-isihlalo sasentwasahlobo; 3, 4, 8, 21-intwasahlobo;
5, 9, 13, 16, 17, 20 - umsesane wokutywina 10 - ivalve yepoppet; I-11 - i-valve core;
22-Undoqo wevalve yendlela enye; 23-iValve umzimba
Okanye i-motor ayiyi kutyibilika ngenxa yobunzima bomthwalo, kwaye iya kusebenza njengesitshixo ngeli xesha. Xa i-cylinder ye-hydraulic okanye i-motor kufuneka ihambe, i-fluid idluliselwa kwelinye isiphaluka seoli, kwaye ngelo xesha, i-oil circuit yangaphakathi ye-valve yokulinganisa ilawula ukuvulwa kwe-valve yokulandelelana ukudibanisa isiphaluka kwaye iqonde ukuhamba kwayo. Ekubeni ukwakhiwa kwevalve yolandelelwano ngokwalo yahlukile kuleyo yeendlela ezimbini zokutshixa i-hydraulic, uxinzelelo oluthile lwasemva lusekwe ngokubanzi kwisekethe yokusebenza xa usebenza, ukuze umsebenzi ophambili we-hydraulic cylinder okanye i-motor ayiyi kuvelisa uxinzelelo olubi. ngenxa yobunzima bayo kunye ne-overspeed sliding, ngoko ke akukho ntshukumo iya phambili iya kwenzeka. Ukothuka kunye nokungcangcazela njengesitshixo se-hydraulic esineendlela ezimbini.
Ngoko ke, iivalve zokulinganisa zisetyenziswa ngokubanzi kwiisekethe ezinesantya esiphezulu kunye nomthwalo onzima kunye neemfuno ezithile zokuzinza kwesantya.
Umzobo we-3 i-valve ye-counterbalance ene-plate structure, kwaye ngezantsi imbono ye-cross-sectional ye-plug-in counterbalance valve.
Ukudibanisa uhlalutyo lwesakhiwo sevalve yokulinganisa kunye ne-hot-way hydraulic lock, umbhali uncoma:
Kwimeko yesantya esiphantsi kunye nomthwalo okhanyayo kunye neemfuno eziphantsi kwi-speed stability, ukwenzela ukunciphisa iindleko, i-lock-way hydraulic lock ingasetyenziswa njengendlela yokuvala isiphaluka. Nangona kunjalo, kwiimeko zesantya esiphezulu kunye nomthwalo onzima, ngakumbi apho iimfuno zokuzinza kwesantya esiphezulu zifunekayo, i-lock-way hydraulic lock kufuneka isetyenziswe. Xa usebenzisa ivalve yebhalansi njengecandelo lokutshixa, akufuneki ulandele ngokumfamekileyo ukuncipha kweendleko kwaye ukhethe indlela ezimbini zokutshixa ulwelo lwamanzi, kungenjalo oko kuya kubangela ilahleko enkulu.
