Ukusetyenziswa kwevalve yokulawula i-hydraulic directional control
2024-03-221.Intshayelelo kwi-valve yokulawula i-hydraulic directional control
Inkcazo kunye nomsebenzi
Ulawula okanye ulawula uxinzelelo, ukuhamba, kunye necala lokuhamba kwamanzi kwiinkqubo zamanzi.
Ulwakhiwo olusisiseko lwevalve yehydraulic:
Ibandakanya undoqo wevalve, umzimba wevalvu kunye nesixhobo (esifana nentwasahlobo) eqhuba undoqo wevalve ukwenza intshukumo ehambelanayo kumzimba wevalvu.
Umgaqo osebenzayo wevalve yehydraulic:
Intshukumo ehambelanayo yondoqo wevalve kumzimba wevalvu isetyenziselwa ukulawula ukuvulwa kunye nokuvala i-valve port kunye nobukhulu be-valve port ukufikelela kulawulo loxinzelelo, ukuhamba kunye nesalathiso.
Ukubaluleka kwiinkqubo zamanzi
• Ubume bevalvu: Yenziwe ngamalungu amathathu: umzimba wevalvu, undoqo wevalvu kunye nesixhobo esiqhuba umbindi wevalvu ukwenza intshukumo ehambelanayo kumzimba wevalvu;
• Umgaqo-nkqubo wokusebenza: Sebenzisa intshukumo ehambelanayo yombindi wevalvu kunye nomzimba wevalvu ukulawula ukuvuleka nokuvalwa kwesivalo sevalvu okanye ubungakanani bendawo yesivalo, ngokwenjenjalo ulawula uxinzelelo, icala lokuhamba kunye nesantya sokuhamba kolwelo;
Ulwelo oluhamba ngeevalvu ezahlukeneyo luya kubangela ukulahleka koxinzelelo kunye nokunyuka kobushushu. Isantya sokuhamba kumngxuma wevalve sinxulumene nendawo yokuhamba kunye nokwahlukana koxinzelelo ngaphambi nangemva kwevalve;
• Ngokusebenza, isivalo sisetyenziselwa ukuhlangabezana noxinzelelo, isantya kunye neemfuno zendlela ye-actuator.
2.Ukusetyenziswa kwevalve yokulawula i-hydraulic directional control
Oomatshini bemizi-mveliso
Iivalvu zeHydraulic zisetyenziswa ngokubanzi kumacandelo ahlukeneyo oxinzelelo lwehydraulic anje ngeesilinda, iimpompo zeoyile, iimotor, iivalve, kunye namavili okuqhuba. Ngokomzekelo, iivalve ze-hydraulic ezisetyenziswa ngokuqhelekileyo kumatshini wokwakha ezifana ne-excavators, i-forklifts, i-roller yeendlela, kunye ne-bulldozers zibandakanya iivalve zokutshekisha, iivalve zokulawula umkhombandlela, iivalve ezilinganayo, njl.
• Izixhobo zokwakha
Iivalvu zeHydraulic zidlala indima ebalulekileyo kushishino lweemoto kwaye zisetyenziswa ikakhulu ukulawula inkqubo ye-hydraulic ye-injini, inkqubo yokukhupha umoya, inkqubo yeziqhoboshi kunye nenkqubo yokuhambisa. Ngokomzekelo, i-valve ye-hydraulic kwi-transmission, i-injector ye-fuel in the high-pressure oil pump, njl.
• oomatshini bezolimo
Iivalve zeHydraulic nazo zinezicelo ezibalulekileyo kwishishini lokwakha iinqanawa, njengokulawula iikhabhinethi zokutshintsha, iicompressors zomoya, izixhobo zentsimi yeoli, njl.
3.Iinzuzo zokusebenzisaivalve yolawulo lwe-hydraulic directional
(1) Isenzo esibucayi, ukusetyenziswa okuthembekileyo, impembelelo encinci kunye nokungcangcazela ngexesha lokusebenza.
(2) Xa i-valve port ivuleke ngokupheleleyo, ilahleko yoxinzelelo lwe-oyile ehamba ngapha incinci. Xa i-valve port ivaliwe, ukusebenza kokutywina kulungile.
(3) Ulwakhiwo olubambeneyo, lula ukuhlohla, ukuhlenga-hlengisa, ukusebenzisa nokugcina, kwaye lunokuguquguquka okukhulu.
I-4.Ukugcinwa kunye neengxaki ze-valve yokulawula i-hydraulic directional control
Ivalve yokubuyisela umva yenye yezinto ezibalulekileyo kwisixokelelwano sehydraulic. Umsebenzi wayo ophambili kukulawula indlela yokuhamba kolwelo kwi-hydraulic system. Nangona kunjalo, ngenxa yokusetyenziswa kwexesha elide kunye nefuthe lezinto zangaphandle, iivalve ezibuyisela umva zinokubandezeleka ngenxa yokungaphumeleli okuqhelekileyo. Eli nqaku liza kuzisa iimpazamo eziqhelekileyo zokubuyisela umva kunye neendlela zabo zokulungisa.
Ukuvuza kweoyile kwivalve yokubuyisela umva:
Ukuvuza kweoyile kwivalve yokubuyisela umva yenye yeempazamo eziqhelekileyo, ezidla ngokubangelwa kukwaluphala okanye ukonakala kwezitywina. Indlela yokulungisa: Okokuqala, khangela ukuba itywina lonakalisiwe. Ukuba yonakele, buyisela itywina. Ukongeza, kufuneka kwakhona ujonge ukuba ujongano olunemisonto lukhululekile. Ukuba ikhululekile, kufuneka iqiniswe kwakhona.
Ivalve yokubuyisela umva ivalekile:
Ivalve ebuyela umva isenokuvaleka, ibangele ukuba ulwelo luqukuqelele kumacala ahlukeneyo. Isizathu sokuvaleka ngokuqhelekileyo ngenxa yezinto ezingcolileyo okanye iincinci ezingena kwisistim ezinamathele kwi-orifice okanye i-valve core ye-valve yokubuyisela umva. Indlela yokulungisa: Okokuqala, kufuneka ususe ungcoliseko kunye namasuntswana kumbindi wevalvu kunye nesitulo sevalvu. Ungasebenzisa ii-agent zokucoca kunye neebrashi ukuze uzicoce. Ukongeza, izihluzi zinokufakelwa ukuthintela ungcoliseko ekungeneni kwinkqubo.
Ivalve yokubuyisela umva ayinakuqaliswa:
Ivalve yokubuyisela umva inokusilela ukuqala ngexesha lokusetyenziswa, ngokuqhelekileyo ngenxa yokusilela kwesekethe okanye umonakalo kwi-electromagnetic. Indlela yokulungisa: Okokuqala, kufuneka ukhangele ukuba umgca wamandla uqhagamshelwe ngokuqhelekileyo. Ukuba uxhulumaniso alulunganga, kufuneka uluqhagamshele kwakhona. Ukongeza, imeko yokusebenza kwe-electromagnetic kufuneka ijongwe. Ukuba i-electromagnetic yonakele, kufuneka itshintshwe.
