Kusanthula ndi Kugwiritsa Ntchito DOUBLE COUNTERBALANCE VALVE
2024-02-20Zomwe zimagwirira ntchito pamakina a engineering ndizovuta. Pofuna kupewa kuyimilira kapena kuthamanga kwambiri pama hydraulic transmission system,mavavu oyenereranthawi zambiri amagwiritsidwa ntchito kuthetsa vutoli. Komabe, kugwedezeka kwapang'onopang'ono kudzachitika panthawi yonyamula katundu, ndipo sikungathetse vuto la kubwereza kapena kusuntha. mavuto obwera chifukwa cha nkhawa komanso kukhumudwa. Chifukwa chake, nkhaniyi ikuwonetsa valavu yolumikizira njira ziwiri kuti ipititse patsogolo zofooka za valve yolinganiza.
1.Mfundo yogwira ntchito ya valve yogwirizanitsa njira ziwiri
Vavu yolumikizira yanjira ziwiri imapangidwa ndi ma valve ofananira omwe amalumikizidwa molumikizana. Chizindikiro chazithunzi chikuwonetsedwa muChithunzi 1. Doko lamafuta owongolera limalumikizidwa ndi kulowa kwamafuta anthambi kumbali inayo. Valavu yolumikizira yanjira ziwiri imapangidwa ndi valavu yayikulu, valavu yanjira imodzi, kasupe wamkulu wa ma mesh ndi kasupe wa valavu imodzi. Doko lowongolera lomwe limapangidwa ndi valavu yayikulu ya valve balance ndi manja a valve njira imodzi.
Chithunzi 1:Chizindikiro chazithunzi cha valavu yolumikizira njira ziwiri
Vavu yolumikizira yanjira ziwiri imakhala ndi ntchito ziwiri: hydraulic lock function ndi dynamic balancing function. Mfundo yogwirira ntchito ya ntchito ziwirizi imawunikidwa makamaka.
Mphamvu yamphamvu yogwira ntchito: Poganiza kuti mafuta opanikizika amachokera ku CI kupita ku actuator, mafuta opanikizika amagonjetsa mphamvu ya masika a valve ya njira imodzi munthambi iyi, zomwe zimapangitsa kuti khomo loyendetsa valavu litseguke, ndipo mafuta othamanga amapita ku actuator. .
Mafuta obwerera amagwira ntchito pachimake cha valve ya nthambi iyi kuchokera ku C2, ndipo pamodzi ndi mafuta oponderezedwa pa doko loyendetsa, amayendetsa kayendedwe ka valavu yaikulu. Chifukwa cha mphamvu zotanuka za pachimake cha valve chachikulu, chipinda chobwezera mafuta cha actuator chimakhala ndi kupanikizika kumbuyo, potero kuwonetsetsa kuyenda bwino kwa actuator. Pamene mafuta opanikizika amachokera ku C2 kupita ku actuator, valve yowunikira pa C2 ndi nsonga yaikulu ya valve pa C1 kusuntha (poyamba, mfundo yogwira ntchito ndi yofanana ndi pamwambapa).
Ntchito ya hydraulic lock: Pamene VI ndi V2 zili pa zero, kuthamanga kwa mafuta pa doko loyendetsa njira ziwiri kumakhala kochepa kwambiri, pafupifupi OMPa. Kuthamanga kwa mafuta mu actuator ndi actuator sikungagonjetse mphamvu ya masika a pachimake valavu, kotero valavu core sungakhoze kusuntha, ndi valavu ya njira imodzi alibe conduction osaya, ndi throttle valavu kulamulira doko ali kutsekedwa boma. Zowongolera ziwiri za actuator zatsekedwa ndipo zimatha kukhala pamalo aliwonse.
Zitsanzo za 2.Engineering za ma valve ogwirizanitsa njira ziwiri
Kupyolera mu kusanthula pamwambapa, valve yoyendetsa njira ziwiri sizimangopangitsa kuti hydraulic actuator ikuyenda bwino, komanso imakhala ndi ntchito ya hydraulic lock, choncho imagwiritsidwa ntchito kwambiri. Nkhaniyi ikufotokoza makamaka zitsanzo za uinjiniya wa katundu wolemetsa komanso kuyenda mobwerezabwereza.
Kugwiritsa ntchito mfundo ya hydraulic m'miyendo yayikulu yamakina omangira njanji yothamanga kwambiri ikuwonetsedwa muChithunzi 3. Miyendo yayikulu yomangira mlatho wa njanji yothamanga kwambiri ili pampumulo. Imathandizira osati kuchuluka kwagalimoto yamakina omangira mlatho wokha, komanso kuchuluka kwa matabwa a konkire. Katunduyo ndi wamkulu ndipo nthawi yothandizira ndi yayitali. Panthawiyi, ntchito ya hydraulic locking ya valve ya njira ziwiri imagwiritsidwa ntchito. Makina omangira mlatho akamakwera ndi kutsika, chifukwa cha kuchuluka kwagalimoto, amafunika kuyenda bwino. Panthawiyi, mphamvu yowonongeka ya valve ya njira ziwiri imagwiritsidwa ntchito. Palinso valavu yamtundu umodzi mu dongosolo, yomwe imawonjezera kupanikizika kumbuyo kwa actuator, kupititsa patsogolo kukhazikika kwa Movement.
Chithunzi 2Miyendo yayikulu yamakina omangira njanji yothamanga kwambiri Chithunzi 3 The boom of the air work platform
Pogwiritsa ntchito ma boom pamapulatifomu amlengalenga, chithunzi cha hydraulic schematic chikuwonetsedwa pa Chithunzi 3 [3]. Pamene mbali ya luffing ya boom ikuwonjezeka kapena kuchepa, kayendetsedwe kake kamayenera kukhala kosalala, ndipo valve ya njira ziwiri imalepheretsa kuyimirira kapena kuthamanga kwambiri panthawi yomwe ikubwereza. Pamakhala ngozi ina.
3.Gawo
Nkhaniyi imayang'ana makamaka kusanthula kwa mfundo zogwirira ntchito ndi kugwiritsa ntchito umisiri wa valavu yanjira ziwiri kuchokera ku hydraulic lock function and dynamic balance function, ndipo imamvetsetsa mozama valavu yanjira ziwiri. Lili ndi katchulidwe kake ka chitukuko ndi kagwiritsidwe ntchito kake.
