Kufotokozera mwachidule za Mbiri ndi Kugwiritsa Ntchito Ma Valves Owongolera a Shantui BulldozersMu chowonjezera cha Shantui bulldozer, valavu yowongolera, monga gawo lofunikira pa chiwongolero, chimagwira gawo lofunikira pakuwongolera kowongolera kwa makinawo. Pakali pano, ngakhale magawo enieni a "msonkhano wowongolera valavu (B)" sanatchulidwe mwachindunji muzotsatira zakusaka, mapangidwe onse ndi chidziwitso chokhudzana ndi chiwongolero cha ma bulldozers a Shantui SD angapo akhoza kuphatikizidwa kuti apereke chidziwitso cha kumvetsetsa kagwiritsidwe ntchito ka ma valve otsogolera kuchokera ku machitidwe a chiwongolero cha machitidwe, machitidwe owonetsera chitsanzo, ndi zina zotero. amatengera kapangidwe kamangidwe kake, ndi valavu yowongolera ngati gawo lowongolera. Amagwiritsidwa ntchito kwambiri pamachitidwe osiyanasiyana opangira ma bulldozer monga uinjiniya wa Earthwork, migodi, ndi zomangamanga, kuonetsetsa chiwongolero chosinthika komanso kuyendetsa bwino kwa zida pansi pazovuta zogwirira ntchito.
Gulu la valavu chowongolera cha bulldozer liyenera kuganizira mozama momwe bulldozer imagwirira ntchito, malo ogwirira ntchito, magawo a hydraulic system, ndi zosowa zenizeni. Nawa miyeso yayikulu ndi njira zenizeni:
Fananizani zoyambira za ma bulldozer
Matani ndi kusintha mphamvu
Matani a bulldozer amatsimikizira mwachindunji kuchuluka kwa kuthamanga ndi kufunikira kwa valavu yowongolera. Mwachitsanzo:
Zing'onozing'ono ndi zapakatikati ({0}}zocheperako kapena zofanana ndi matani a 20): Kawirikawiri sankhani valavu yoyendetsa ndi kuthamanga kwa 10-20MPa ndi kuthamanga kwa 40-100L/min, monga ZT mndandanda wa hydraulic directional valve (kuthamanga kwa 40-100s / min kapena kutsika kwa Les2 MP).
Large bulldozers (>matani 20): amayenera kufananizidwa ndi mawonekedwe apamwamba, monga chiwongolero cha brake chowongolera chomwe chimagwiritsidwa ntchito mu bulldozer ya 520 horsepower, ndi kuthamanga kwa 246L/min ndi kupanikizika kwa 2.69MPa, kuphatikizika ndi -valavu yotsekera kuti athe kuthana ndi katundu wolemetsa komanso malo ovuta.
Kufananiza mphamvu: Onani mphamvu ya injini ya flywheel (monga 447kW ya Caterpillar D10T2) kuti muwonetsetse kuti valavu yowongolera imatha kupirira kuthamanga kwamphamvu kwa hydraulic system yonse.
Kugwirizana kwachitsanzo
Pali kusiyana kwakukulu pakupanga machitidwe owongolera pakati pamitundu yosiyanasiyana. Mwachitsanzo:
Crawler bulldozer: Ndikofunikira kusankha valavu yowongolera yomwe imathandizira kuwongolera kuthamanga kwa liwiro, monga 16Y-76-22000 chiwongolero chopangidwira makamaka ma bulldozer a SD16, omwe amatha kulumikizidwa ndi brake clutch kuti akwaniritse chiwongolero cholondola.
Wheeled bulldozer: Ganizirani zophatikizira valavu yokulirapo (monga mtundu wa VSFA) yokhala ndi zida zowongolera kuti muwongolere kuyendetsa bwino pogwiritsa ntchito mfundo yokulitsa molingana.
Sinthani ku malo ogwirira ntchito komanso momwe amagwirira ntchito
Madera ndi katundu
Madera ovuta (migodi, mapiri): Chofunika kwambiri chiyenera kuperekedwa kwa ma valve oyendetsa omwe ali ndi chiwongoladzanja chokakamiza, monga ma valve ophatikizira okhala ndi ma valve otetezedwa otetezedwa, omwe amatha kuchepetsa kupanikizika pamene njanjiyo yakhazikika (kuponderezedwa kwa 10-30MPa) kuteteza kuwonongeka kwa zigawo za hydraulic.
Bulldozer ya katundu wolemera: M'pofunika kusankha zida za mavavu zomwe zimakhala zolimba kwambiri (monga -chitsulo chonyezimira champhamvu kapena chitsulo), ndikuwonetsetsa kuti valavu ikugwira ntchito. Mwachitsanzo, ma valve cores omwe amakutidwa ndi tungsten carbide amatha kupirira nthawi zambiri akanyamula katundu wolemetsa.
Kuteteza kwambiri chilengedwe
Kutentha kwapamwamba/kutsika: Sankhani zida zolimbana ndi kutentha (monga zitsulo za silicon carbide ceramic valve zomwe zimatha kupirira kutentha mpaka madigiri 1600) kapena ma valve olunjika omwe ali ndi chipukuta misozi chowongolera kutentha kuti mupewe kupanikizana kwa mavavu chifukwa cha kufutukuka ndi kutsika kwa matenthedwe.
Fumbi lalikulu/malo ochita dzimbiri: Kutengera zitsulo zosapanga dzimbiri (monga 2205) kapena valavu ya Hastelloy, yokhala ndi O-yotsekera mphete (monga fluororubber VITON) kuteteza kulowerera kwa fumbi komanso dzimbiri.
Kufananiza kwa magawo a hydraulic system
Kuthamanga ndi kuthamanga kofanana
Kuwerengera koyenda: Kutengera kuthamanga kwa silinda yoyendetsera (monga kuthamanga kwa piston rod 50mm / s) ndi silinda ya silinda (monga φ 125mm), kuwerengera kuchuluka kwamayendedwe ofunikira (Q=π× r ² × v) kuti muwonetsetse kuti kuthamanga kwambiri kwa valavu yowongolera (monga 0L/min)
Kupanikizika kwapakati: Kuthamanga kwa valve yoyendetsa kuyenera kukhala kwakukulu kuposa kuthamanga kwapamwamba kwa dongosolo (nthawi zambiri 1.2-1.5 nthawi yogwira ntchito). Mwachitsanzo, pamene kuthamanga kwa ntchito ndi 15MPa, valavu yokhala ndi mphamvu ya 20MPa iyenera kusankhidwa.
Kugwirizana kwamafuta
Tsimikizirani mtundu wamafuta amtundu wa hydraulic (monga mafuta amchere, mafuta opangira) ndi mawonekedwe a viscosity (monga ISO VG 46) oyenera valavu yowongolera kuti mupewe kukalamba kwa chisindikizo kapena kupindika kwapakati kwa valve chifukwa cha kusagwirizana kwamafuta.
Zofunikira za magwiridwe antchito
Kuwongolera kulondola ndi liwiro la kuyankha
Sensitivity of valve core: Sankhani chiwongolero chowongolera chomwe chili ndi mphamvu zofananira kapena zowongolera zamagetsi (monga BPBS hydraulic steering gear + VSFA flow amplification valve) kuti mukwaniritse "kusintha kwabwino pang'ono" ndikuyankha mwachangu, kuwongolera magwiridwe antchito.
Kubwereranso kudalirika: Ndikoyenera kuyang'ana kuuma kwa kasupe wobwerera ndi ubwino wa zigawo zosindikizira kuti zitsimikizire kuti chigawo cha valve chimabwerera mwamsanga pakati pambuyo potulutsa ndodo yoyendetsa, kupewa kupatuka.
Chitetezo ndi redundancy kupanga
Kudzikhoma komanso kuletsa kulakwa: Mwachitsanzo, chiwongolero cha brake brake bulldozer ya 520 horsepower bulldozer imalumikiza valavu yodzitsekera yokha{1}}. Poyambira, chogwiriracho chiyenera kubwezeretsedwa pamalo ake oyambirira kuti ateteze ngozi zomwe zimachitika chifukwa cha misoperation.
Dongosolo lowonjezera: Pazinthu zodalirika kwambiri monga migodi, ma valve owongolera osafunikira okhala ndi ma valve osungira solenoid amatha kusankhidwa. Vavu yayikulu ikalephera, imangosinthira kudera losunga zobwezeretsera, kuchepetsa nthawi yopumira.
