Ukukhetha Okulungile Kokhiye Wezindlela Ezimbili Wamandla Kagesi kanye nama-Balance Valves kumaHydraulic Systems
2024-02-20Izici zesakhiwo se-two-way hydraulic lock:
Ilokhi ye-hydraulic lock ngamavalvu amabili alawulwa ngendlela eyodwa esebenzisa amanzi asetshenziswa ndawonye. Ivamise ukusetshenziswa kumasilinda kawoyela athwala umthwalo noma amasekhethi kawoyela enjini ukuze kuvinjwe isilinda esisebenza ngaphansi kwamanzi noma imotor ukuthi ingasheleli phansi ngaphansi kokwenziwa kwezinto ezisindayo. Uma isenzo sidingeka, uwoyela kufanele uhlinzekwe kwenye isekethe, futhi i-valve yendlela eyodwa kufanele ivulwe ngesekhethi kawoyela yokulawula kwangaphakathi ukuze isekethe kawoyela isebenze Kuphela uma ixhunyiwe lapho isilinda esisebenza ngaphansi kwamanzi noma i-motor.
Ngenxa yesakhiwo semishini ngokwayo, ngesikhathi sokuhamba kwe-cylinder ye-hydraulic, isisindo esifile somthwalo sivame ukubangela ukulahlekelwa okusheshayo kokucindezela ekamelweni lokusebenza eliyinhloko, okuholela ekushayweni.
Lesi simo sivame ukwenzeka emishinini elandelayo evamile:
①Isilinda samafutha esibekwe mpo emshinini wokunyathelisa we-hydraulic wamakholomu amane;
② Isilinda sesikhunta esiphezulu semishini yokwenza izitini;
③Swing cylinder yemishini yokwakha;
④Injini yokuwina ye-hydraulic crane;
Ilokhi ye-hydraulic esetshenziswa kakhulu ivalvu estakiwe yendlela eyodwa. Lapho into esindayo iwe ngesisindo sayo, uma uhlangothi lwamafutha okulawula lungagcwaliswa ngesikhathi, kuzokwenziwa ivacuum ohlangothini lwe-B, okubangela ukuthi i-piston yokulawula ihlehle ngaphansi kwesenzo sentwasahlobo, okubangela i-valve yendlela eyodwa. kuya I-valve ivaliwe, bese ukunikezwa kukawoyela kuqhubeka nokwandisa ingcindezi ekamelweni lokusebenza bese kuvulwa i-valve yendlela eyodwa. Izenzo ezinjalo zokuvula nokuvala njalo zizobangela umthwalo ukuthi uqhubeke kancane kancane phakathi nenqubo yokuwa, okuholela kumthelela omkhulu nokudlidliza. Ngakho-ke, izingidi ezimbili ze-hydraulic ngokuvamile azinconywa ngezimo zejubane eliphezulu kanye nomthwalo osindayo, kodwa zivame ukusetshenziswa. Ifanele izihibe ezivaliwe ezinesikhathi eside sokusekela kanye nesivinini esiphansi sokunyakaza.
2. Izici zesakhiwo se-valve yebhalansi:
I-valve yebhalansi, eyaziwa nangokuthi isikhiya somkhawulo wejubane, iyivalvu elawulwa ngaphandle yokuvuza yangaphakathi yendlela eyodwa. Iqukethe i-valve yendlela eyodwa kanye ne-valve yokulandelana esetshenziswa ndawonye. Kumjikelezo we-hydraulic, ingavimba uwoyela kusilinda wehydraulic noma isekethe kawoyela wemoto. Uketshezi luvimbela isilinda esisebenza ngaphansi kwamanzi noma i-motor ukuthi ingasheleli phansi ngenxa yesisindo somthwalo, futhi sisebenza njengesikhiya ngalesi sikhathi.
Lapho i-hydraulic cylinder noma i-motor idinga ukunyakaza, uketshezi ludluliselwa kwesinye isifunda samafutha, futhi ngesikhathi esifanayo, isifunda samafutha sangaphakathi se-valve yebhalansi silawula ukuvulwa kwe-valve yokulandelana ukuxhuma isifunda futhi uqaphele ukunyakaza kwayo. Njengoba isakhiwo se-valve yokulandelana ngokwaso sihlukile kunesokukhiya kwe-hydraulic lock, ingcindezi ethile yangemuva ngokuvamile isungulwa kumjikelezo wokusebenza lapho isebenza, ukuze umsebenzi oyinhloko we-hydraulic cylinder noma i-motor ngeke ukhiqize ukucindezela okungalungile. ngenxa yesisindo sayo kanye nokushelela ngesivinini esikhulu, ngakho-ke akukho mnyakazo oya phambili ozokwenzeka. Ukushaqeka nokudlidliza okufana nokhiye we-hydraulic lock.
Ngakho-ke, ama-valve ebhalansi ngokuvamile asetshenziswa kumasekhethi anesivinini esikhulu nomthwalo osindayo kanye nezidingo ezithile zokuzinza kwejubane.
3. Ukuqhathaniswa kwamavalvu amabili:
Ngokuqhathanisa, singabona ukuthi lapho usebenzisa ama-valve amabili, kufanele akhethwe ngokuvumelana nezimo ngokuvumelana nezidingo zemishini, futhi kufanele asetshenziswe ndawonye lapho kudingekile.
4.Kuhlanganiswe nokuhlaziywa kwesakhiwo se-valve yebhalansi kanye ne-two-way hydraulic lock, sincoma:
① Esimeni sejubane eliphansi kanye nomthwalo omncane onezidingo zokuzinza kwesivinini esiphansi, ukuze kwehliswe izindleko, ukukhiya kwe-hydraulic okunezindlela ezimbili kungasetshenziswa njengokhiye wesekethe.
② Ezimweni zesivinini esikhulu kanye nemithwalo esindayo, ikakhulukazi lapho izidingo zokuzinza kwesivinini esiphezulu zidingeka, i-valve yebhalansi kufanele isetshenziswe njengengxenye yokukhiya. Ungajahi ukwehlisa izindleko ngobumpumputhe futhi usebenzise ilokhi ye-hydraulic lock, ngaphandle kwalokho izodala ukulahlekelwa okukhulu.
