3. Malinga ndi dongosolo logwirira ntchito ndi kuthamanga (kuthamanga kwa ntchito) ndikuganizirani mtundu wa valve, kukhazikitsa ndi kulumikiza njira, njira yogwiritsira ntchito, sing'anga yogwira ntchito, kukula ndi khalidwe, moyo wogwira ntchito, chuma, kusinthasintha ndi kukonza mosavuta, kupereka ndi mankhwala. mbiri ndi zina zimasankhidwa kuchokera m'mabuku oyenerera opangira kapena zitsanzo za mankhwala.
Mtundu kusankha kwa hydraulic valve
Zofunikira zogwirira ntchito za hydraulic system ndizosiyana, ndipo zofunikira za valavu yosankhidwa ya hydraulic ndizosiyana, ndipo machitidwe ambiri amakhudzidwa ndi mawonekedwe apangidwe.Mwachitsanzo, pamakina omwe amafunikira kuthamangitsidwa mwachangu, valavu yosinthira ma elekitiroma ya AC nthawi zambiri imasankhidwa;m'malo mwake, pamakina omwe amafunikira kuthamanga pang'onopang'ono, valavu yamagetsi yamagetsi ya DC imatha kusankhidwa;mwachitsanzo, mu hydraulic system, spool reset ndi centering performance Ngati zofunikira zimakhala zovuta kwambiri, hydraulic centering structure ikhoza kusankhidwa;ngati valavu yoyang'aniridwa ndi hydraulically ikugwiritsidwa ntchito, ndipo kupanikizika kumbuyo kwa mafuta obwerera kumbuyo kumakhala kwakukulu, koma kukakamiza kolamulira sikungakwezedwe kwambiri, mtundu wa kutuluka kunja kapena mtundu woyendetsa ndege uyenera kusankhidwa.Kapangidwe: Kuti valve yopanikizika iteteze chitetezo cha dongosolo, imayenera kukhala ndi yankho lachidziwitso, kuponderezedwa pang'ono, kupeŵa kupanikizika kwakukulu, ndi kuyamwa mphamvu yomwe imachokera pamene valve yobwerera imasinthidwa, kotero ndizovuta kwambiri. zofunikira kusankha zigawo zomwe zingakwaniritse zomwe zili pamwambazi.;Ngati valavu yothamanga kwambiri siyingathe kukwaniritsa zofunikira za kayendedwe ka actuator chifukwa cha kusintha kwa kuthamanga kapena kutentha, valve yoyendetsa liwiro yokhala ndi chipangizo cholipirira chiwongoladzanja kapena chipangizo chobwezera kutentha chiyenera kusankhidwa.
Kusankhidwa kwa Nominal Pressure and Rated Flow
(1) Kusankha kuthamanga mwadzina (kupanikizika kovomerezeka)
Valavu ya hydraulic ya mulingo wofananira wopanikizika imatha kusankhidwa molingana ndi kukakamiza kogwirira ntchito komwe kumapangidwira pamapangidwe adongosolo, ndipo kukakamiza kwadongosolo kwadongosolo kuyenera kukhala kocheperako kuposa kuchuluka kwamphamvu kwadzina komwe kumawonetsedwa pazogulitsa.Ma hydraulic valves amtundu wothamanga kwambiri nthawi zambiri amagwira ntchito kumagulu onse ogwira ntchito omwe ali pansi pa kukakamizidwa.Komabe, zizindikiro zina zaumisiri zomwe zimapangidwira zigawo za hydraulic zotsika kwambiri pansi pamikhalidwe yoyezetsa zitha kukhala zosiyana pang'ono ndi zovuta zosiyanasiyana zogwirira ntchito, ndipo zizindikiro zina zikhala bwino.Ngati mphamvu yeniyeni yogwira ntchito ya hydraulic system ndi yokwera pang'ono kusiyana ndi mtengo wamtengo wapatali womwe umasonyezedwa ndi hydraulic valve mu nthawi yochepa, nthawi zambiri amaloledwa.Koma sikuloledwa kugwira ntchito m'derali kwa nthawi yayitali, mwinamwake izo zidzakhudza moyo wabwino wa mankhwala ndi zizindikiro zina za ntchito.
(2) Kusankhidwa kwa kayendedwe kovotera
Kuthamanga kwa valavu iliyonse ya hydraulic control valve kuyenera kukhala pafupi ndi kayendedwe kake kakugwira ntchito, komwe ndi kotsika mtengo komanso koyenera.N'zothekanso kugwiritsa ntchito valavu panthawi yochepa kwambiri, koma ngati valavu ikugwira ntchito ndi kayendedwe kake kakakulu kuposa momwe amachitira kwa nthawi yaitali, n'zosavuta kuyambitsa hydraulic clamping ndi mphamvu ya hydraulic ndipo imakhudza kwambiri. khalidwe la ntchito ya valve.
Kuthamanga kwa dera lililonse la mafuta mu hydraulic system sikungakhale kofanana, kotero magawo othamanga a valve sangathe kusankhidwa molingana ndi kuchuluka kwa kutuluka kwa gwero la hydraulic, koma zotheka kutuluka kwa valve iliyonse kupyolera mu hydraulic system pansi pa zonse. Magawo apangidwe ayenera kuganiziridwa.Kuthamanga kwakukulu kothamanga, mwachitsanzo, kuthamanga kwa maulendo amtundu wa mafuta ndi ofanana;kuchuluka kwa kayendedwe ka mafuta oyendera limodzi komwe kumagwira ntchito nthawi imodzi ndi kofanana ndi kuchuluka kwamayendedwe amtundu uliwonse wamafuta;kwa valavu yobwereranso ya silinda ya hydraulic hydraulic, kusankha koyenda kuyenera kuganizira zakusintha kwa silinda ya hydraulic., Kuthamanga kwa kayendedwe kamene kamatulutsidwa kuchokera ku ndodo yopanda ndodo ndi yaikulu kwambiri kuposa ya ndodo ya ndodo, ndipo ingakhale yaikulu kuposa kutulutsa kwakukulu kotuluka ndi pampu ya hydraulic;kwa valavu yotsatizana ndi valavu yochepetsera kuthamanga mu dongosolo, kayendetsedwe ka ntchito sikuyenera kukhala kakang'ono kwambiri kusiyana ndi kuthamanga kwake.Apo ayi, kugwedezeka kapena zochitika zina zosakhazikika zidzachitika mosavuta;kwa ma throttle valves ndi ma valve oyendetsa liwiro, chidwi chiyenera kulipidwa pakuyenda kosasunthika kocheperako.
