Ukukhetha i-valve ye-hydraulic efanele kuyisimo esibalulekile sokwenza uhlelo lwe-hydraulic luhlakazeke ekwakhiweni, luhle kakhulu ekusebenzeni kwezobuchwepheshe nezomnotho, kulula ukuyifaka nokugcina, nokuqinisekisa ukusebenza okuvamile kwesistimu.Ngenxa yokuthi ukukhethwa kwe-valve ye-hydraulic kulungile noma cha, kunobudlelwane obukhulu nempumelelo noma ukwehluleka kwesistimu, ngakho-ke kufanele kuthathwe ngokungathí sina.
Izimiso ezijwayelekile zokukhetha
1. Ngokwezidingo zemisebenzi yokushayela nokulawula yesistimu, khetha ngokunengqondo umsebenzi nezinhlobonhlobo ze-valve edonsa amanzi, futhi yakha isekethe ye-hydraulic ephelele kanye nomdwebo weskimu wesistimu kanye nepompo ye-hydraulic, i-actuator kanye nezinsiza zokusebenzisa amanzi.
2. Imikhiqizo ekhona yochungechunge olujwayelekile iyakhethwa, futhi ama-valve okulawula amanzi akhethekile aklanywa ngokwawo ngaphandle uma kunesidingo.
3. Ngokusho kwengcindezi yokusebenza kwesistimu nangokugeleza (ukugeleza kokusebenza) futhi ucabangele uhlobo lwe-valve, ukufakwa kanye nendlela yokuxhuma, indlela yokusebenza, indawo yokusebenza, usayizi kanye nekhwalithi, impilo yokusebenza, umnotho, ukuzivumelanisa nezimo nokugcinwa kalula, ukuhlinzekwa kanye nomkhiqizo. umlando njll. zikhethwa kumamanuwali edizayini afanelekile noma amasampula omkhiqizo.
Uhlobo lokukhethwa kwe-valve ye-hydraulic
Izidingo zokusebenza zesistimu ye-hydraulic zihlukile, futhi izidingo zokusebenza ze-valve ye-hydraulic ekhethiwe nazo zihlukile, futhi ukusebenza okuningi kuthinteka yizici zesakhiwo.Isibonelo, ohlelweni oludinga isivinini sokubuyisela emuva ngokushesha, kuvamise ukukhethwa ivalvu ehlehlayo kagesi kagesi ye-AC;ngokuphambene nalokho, ohlelweni oludinga isivinini esisheshayo sokubuyisela emuva, i-valve ye-DC electromagnetic reversing valve ingakhethwa;isibonelo, ohlelweni lwe-hydraulic, ukusetha kabusha kwe-spool nokusebenza kwe-centering Uma izidingo ziqinile ikakhulukazi, isakhiwo se-hydraulic centering singakhethwa;uma i-valve yokuhlola elawulwa nge-hydraulically isetshenziswa, futhi ingcindezi yangemuva ye-outlet yamafutha e-reverse iphezulu, kodwa ukucindezela kokulawula akukwazi ukuphakanyiswa kakhulu, uhlobo lokuvuza kwangaphandle noma uhlobo lomshayeli kufanele lukhethwe.Isakhiwo: Ukuze i-valve yokucindezela ivikele ukuphepha kwesistimu, iyadingeka ukuthi ibe nokuphendula okubucayi, i-overshoot encane yokucindezela, ukugwema ukucindezela okukhulu komthelela, nokudonsa umthelela owenziwe lapho i-valve yokuhlehla ihlehliswa, ngakho-ke kudingekile ukukhetha izingxenye ezingahlangabezana nezidingo zokusebenza ezingenhla.;Uma i-valve evamile yokugeleza ingakwazi ukuhlangabezana nezidingo zokunemba kokunyakaza kwe-actuator ngenxa yezinguquko zokucindezela noma izinga lokushisa, i-valve elawula isivinini enedivayisi yesinxephezelo sokucindezela noma idivayisi yesinxephezelo sezinga lokushisa kufanele kukhethwe.
Ukukhethwa Kwengcindezi Yokuzisholo kanye Nokugeleza Okulinganiselwe
(1) Ukukhethwa kwengcindezi yamagama (ingcindezi elinganiselwe)
I-valve ye-hydraulic yezinga lokucindezela elihambisanayo ingakhethwa ngokuvumelana nengcindezi yokusebenza enqunywe ekwakhiweni kwesistimu, futhi ingcindezi yokusebenza yesistimu kufanele ibe ngaphansi ngokufanele kunevelu yokucindezela okulinganiselwe ekhonjiswe kumkhiqizo.Amavalvu e-hydraulic ochungechunge lwe-high pressure ngokuvamile asebenza kuwo wonke amazinga okucindezela okusebenzayo ngaphansi kwengcindezi elinganiselwe.Nokho, ezinye izinkomba zobuchwepheshe ezakhelwe izingxenye zamanzi ezinomfutho ophezulu ngaphansi kwezimo zengcindezi elinganiselwe zizohluka ngandlela thize ngaphansi kwengcindezi yokusebenza ehlukene, futhi ezinye izinkomba zizoba ngcono.Uma ingcindezi yangempela yokusebenza yesistimu ye-hydraulic iphakeme kancane kunevelu yokucindezela elinganiselwe ekhonjiswe i-valve ye-hydraulic ngesikhathi esifushane, ngokuvamile kuvunyelwe.Kodwa akuvunyelwe ukusebenza kulesi simo isikhathi eside, ngaphandle kwalokho kuzothinta impilo evamile yomkhiqizo kanye nezinye izinkomba zokusebenza.
(2) Ukukhethwa kokugeleza okulinganiselwe
Ukugeleza okulinganiselwe kwe-valve yokulawula i-hydraulic ngayinye kufanele ngokuvamile kusondele ekusebenzeni kwayo, okufana nokonga kakhulu nokunengqondo.Kungenzeka futhi ukusebenzisa i-valve esimweni sokugeleza ngokweqile kwesikhathi esifushane, kodwa uma i-valve isebenza ngokugeleza kokusebenza okukhulu kunokugeleza okulinganiselwe isikhathi eside, kulula ukubangela i-hydraulic clamping namandla we-hydraulic futhi ithinte kabi ikhwalithi yokusebenza ye-valve.
Ukugeleza kwesekethe ngayinye kawoyela ohlelweni lwe-hydraulic ayikwazi ukufana, ngakho-ke imingcele yokugeleza ye-valve ayikwazi ukukhethwa ngokumane ngokuhambisana nokugeleza okuphezulu kokuphuma komthombo we-hydraulic, kodwa ukugeleza okungenzeka kwe-valve ngayinye ngokusebenzisa uhlelo lwe-hydraulic ngaphansi kwakho konke. izimo zokuklama kufanele zicatshangelwe.Isilinganiso esiphezulu sokugeleza, isibonelo, izinga lokugeleza kwesifunda samafutha ochungechunge liyalingana;izinga lokugeleza kwe-parallel oil circuit elisebenza ngesikhathi esifanayo lilingana nesamba samazinga okugeleza kwesifunda ngasinye samafutha;ku-valve ehlehlayo yesilinda se-hydraulic ehlukile, ukukhethwa kokugeleza kufanele kucabangele isenzo sokuhlehla se-cylinder ye-hydraulic., Izinga lokugeleza elikhishwe emgodini ongenalutho likhulu kakhulu kune-cavity yenduku, futhi lingase libe likhulu kunomphumela omkhulu wokugeleza ngepompo ye-hydraulic;nge-valve yokulandelana kanye ne-valve yokunciphisa ingcindezi ohlelweni, ukugeleza kokusebenza akufanele kube kuncane kakhulu kunokugeleza okulinganiselwe.Uma kungenjalo, ukudlidliza noma ezinye izinto ezingazinzile zizokwenzeka kalula;kuma-valve e-throttle kanye nama-valve okulawula isivinini, ukunakwa kufanele kukhokhwe ekugelezeni okuncane okuzinzile.
