Kusankha Molondola kwa Maloko Awiri a Hydraulic Locks ndi Balance Valves mu Hydraulic Systems
2024-02-20Mawonekedwe a njira ziwiri za hydraulic lock:
The two way hydraulic lock ndi ma valve awiri oyendetsedwa ndi hydraulic anjira imodzi omwe amagwiritsidwa ntchito palimodzi. Nthawi zambiri amagwiritsidwa ntchito m'masilinda onyamula ma hydraulic cylinders kapena mabwalo amafuta amagalimoto kuti ateteze silinda ya hydraulic kapena mota kuti isatsetsereke pansi pochita zinthu zolemetsa. Pakafunika kuchitapo kanthu, mafuta ayenera kuperekedwa kudera lina, ndipo valavu yanjira imodzi iyenera kutsegulidwa kudzera mumayendedwe owongolera mafuta kuti alole kuzungulira kwamafuta Pokhapokha atalumikizidwa ndi hydraulic cylinder kapena motor.
Chifukwa cha makina akewo, pakuyenda kwa silinda ya hydraulic, kulemera kwakufa kwa katunduyo nthawi zambiri kumayambitsa kutayika kwachangu m'chipinda chachikulu chogwirira ntchito, zomwe zimapangitsa kuti pakhale vacuum.
Izi zimachitika nthawi zambiri pamakina awa:
①Silinda yamafuta yomwe imayikidwa moyima mu makina osindikizira amitundu inayi;
② Chapamwamba nkhungu yamphamvu makina opanga njerwa;
③ Swing yamphamvu yamakina omanga;
④Moto ya winch ya hydraulic crane;
Chotsekera cha hydraulic chomwe chimagwiritsidwa ntchito kwambiri ndi valavu yanjira imodzi. Chinthu cholemera chikagwa ndi kulemera kwake, ngati mbali ya mafuta olamulira siinadzazidwenso panthawi yake, phokoso lidzapangidwa kumbali ya B, zomwe zimapangitsa kuti pisitoni yolamulira ibwerere pansi pa zochitika za kasupe, zomwe zimapangitsa kuti valve ya njira imodzi. ku Vavu yatsekedwa, ndiyeno mafuta akupitilizidwa kuonjezera kupanikizika mu chipinda chogwirira ntchito ndiyeno valavu ya njira imodzi imatsegulidwa. Kutsegula ndi kutseka pafupipafupi kotereku kumapangitsa kuti katunduyo apite patsogolo pang'onopang'ono panthawi yakugwa, zomwe zimapangitsa kuti pakhale kugwedezeka kwakukulu ndi kugwedezeka. Choncho, njira ziwiri zotsekera ma hydraulic locks nthawi zambiri sizimalimbikitsidwa kuti zikhale zothamanga kwambiri komanso zolemetsa, koma zimagwiritsidwa ntchito kwambiri. Ndizoyenera malupu otsekedwa ndi nthawi yayitali yothandizira komanso kuthamanga kwapansi.
2.Mapangidwe a valve balance:
Valve yocheperako, yomwe imadziwikanso kuti liwiro lotsekera, ndi valavu yoyendetsedwa ndikunja yotuluka mkati mwa njira imodzi. Amakhala ndi valavu yanjira imodzi ndi valavu yotsatizana yomwe imagwiritsidwa ntchito palimodzi. Mu hydraulic circuit, imatha kuletsa mafuta mu hydraulic cylinder kapena motor oil circuit. Madzimadzi amalepheretsa silinda ya hydraulic kapena mota kuti isagwere chifukwa cha kulemera kwa katunduyo, ndipo imakhala ngati loko panthawiyi.
Pamene hydraulic cylinder kapena motor ikufunika kusuntha, madzimadzi amaperekedwa ku dera lina la mafuta, ndipo nthawi yomweyo, dera lamkati la mafuta la valve balance limayang'anira kutsegula kwa valve yotsatizana kuti igwirizane ndi dera ndikuzindikira kayendedwe kake. Popeza kapangidwe ka valve yotsatizana yokha ndi yosiyana ndi njira ziwiri za hydraulic loko, kupanikizika kwina kumbuyo kumakhazikitsidwa pafupipafupi pogwira ntchito, kuti ntchito yayikulu ya silinda ya hydraulic kapena mota isapangitse kupanikizika koyipa. chifukwa cha kulemera kwake komanso kutsetsereka kothamanga kwambiri, kotero palibe kuyenda kwamtsogolo komwe kudzachitika. Kugwedezeka ndi kugwedezeka ngati loko ya hydraulic lock.
Chifukwa chake, ma valve owerengera nthawi zambiri amagwiritsidwa ntchito m'mabwalo okhala ndi liwiro lalitali komanso katundu wolemetsa komanso zofunika zina zokhazikika.
3.Kufananiza mavavu awiriwa:
Kupyolera mu kuyerekezera, tikhoza kuona kuti pogwiritsira ntchito ma valve awiriwa, ayenera kusankhidwa mosinthasintha malinga ndi zosowa za zipangizo, ndipo ayenera kugwiritsidwa ntchito palimodzi ngati kuli kofunikira.
4.Kuphatikizidwa ndi kusanthula kwadongosolo la valve balance ndi njira ziwiri za hydraulic lock, timalimbikitsa:
① Pankhani ya liwiro lotsika komanso katundu wopepuka wokhala ndi zofunikira zokhazikika, kuti muchepetse mtengo, loko yanjira ziwiri ya hydraulic ingagwiritsidwe ntchito ngati loko yozungulira.
② Muzochitika zothamanga kwambiri komanso zolemetsa, makamaka pamene zofunikira zokhazikika zothamanga zimafunika, valve yoyendetsera bwino iyenera kugwiritsidwa ntchito ngati chigawo chotseka. Osatsata mwachimbulimbuli kuchepetsa mtengo ndikugwiritsa ntchito loko yanjira ziwiri za hydraulic, apo ayi zitha kuwononga kwambiri.
