Kugwiritsa ntchito ma hydraulic directional control valve
2024-03-221.Chiyambi cha hydraulic directional control valve
Tanthauzo ndi ntchito
Imawongolera kapena kuwongolera kuthamanga, kuyenda, ndi komwe kumayenda kwamadzi mumayendedwe a hydraulic.
Mapangidwe oyambira a hydraulic valve:
Zimaphatikizapo chigawo cha valve, thupi la valve ndi chipangizo (monga kasupe) chomwe chimayendetsa pakatikati pa valve kuti chiziyenda mozungulira mu thupi la valve.
Mfundo yogwirira ntchito ya hydraulic valve:
Kuyenda pang'onopang'ono kwapakati pa valve mu thupi la valve kumagwiritsidwa ntchito poyang'anira kutsegula ndi kutseka kwa doko la valve ndi kukula kwa khomo la valve kuti akwaniritse kuwongolera, kuyenda ndi njira.
Kufunika kwa ma hydraulic systems
• Mapangidwe a valavu: Amapangidwa ndi zigawo zitatu: thupi la valve, mphutsi ya valve ndi chipangizo chomwe chimayendetsa chigawo cha valve kuti chipangitse kayendetsedwe kake mu thupi la valve;
• Mfundo yogwira ntchito: Gwiritsani ntchito kayendedwe ka valve core ndi thupi la valve kuti muyang'ane kutsegula ndi kutseka kwa khomo la valve kapena kukula kwa khomo la valve, potero kuwongolera kuthamanga, kayendedwe ka kayendedwe ka madzi ndi kuthamanga kwa madzi;
Zamadzimadzi zomwe zimayenda m'mavavu osiyanasiyana zipangitsa kutsika kwamphamvu komanso kukwera kwa kutentha. Kuthamanga kwapakati pa dzenje la valve kumagwirizana ndi malo othamanga ndi kusiyana kwa kuthamanga musanayambe ndi pambuyo pake;
• Mwachidziwitso, valavu imagwiritsidwa ntchito pokwaniritsa kukakamizidwa, kuthamanga ndi mayendedwe a actuator.
2.Kugwiritsidwa ntchito kwa hydraulic directional control valve
Makina opanga mafakitale
Mavavu a Hydraulic amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zama hydraulic monga masilindala, mapampu amafuta, ma mota, ma valve, ndi mawilo owongolera. Mwachitsanzo, ma hydraulic valves omwe amagwiritsidwa ntchito kwambiri pamakina omanga monga ofukula, ma forklift, ma roller amsewu, ndi ma bulldozer amaphatikiza ma cheke, ma valve owongolera, ma valve olingana, ndi zina zambiri.
• Zida zomangira
Mavavu a Hydraulic amagwira ntchito yofunika kwambiri pamakampani amagalimoto ndipo amagwiritsidwa ntchito makamaka kuwongolera ma hydraulic system, makina otulutsa mpweya, ma braking system ndi ma transmission system. Mwachitsanzo, valavu hayidiroliki mu kufala, jekeseni mafuta mu mkulu-anzanu mafuta mpope, etc.
• makina aulimi
Mavavu a Hydraulic amakhalanso ndi ntchito zofunika pamakampani opanga zombo, monga kuwongolera makabati osinthira, ma compressor a mpweya, zida zakumunda wamafuta, ndi zina zambiri.
3.Ubwino wogwiritsa ntchitohydraulic directional control valve
(1) Kuchita movutikira, kugwiritsa ntchito kodalirika, kukhudzidwa pang'ono ndi kugwedezeka pakugwira ntchito.
(2) Chitseko cha valve chikatsegulidwa kwathunthu, kutayika kwa mafuta othamanga kumakhala kochepa. Pamene khomo la valve latsekedwa, ntchito yosindikiza imakhala yabwino.
(3) Kapangidwe kakang'ono, kosavuta kukhazikitsa, kusintha, kugwiritsa ntchito ndi kukonza, ndipo kumakhala kosiyanasiyana.
4.Kukonza ndi kuthetsa mavuto a hydraulic directional control valve
Vavu yobwereranso ndi imodzi mwazinthu zofunika kwambiri mu hydraulic system. Ntchito yake yayikulu ndikuwongolera kayendedwe ka madzimadzi mu hydraulic system. Komabe, chifukwa cha kugwiritsidwa ntchito kwa nthawi yayitali komanso mphamvu ya zinthu zakunja, ma valve obwezeretsa amatha kuvutika ndi zolephera zina. Nkhaniyi ifotokoza zolakwika zomwe zimachitika kawirikawiri pamavavu obwezeretsa ndi njira zawo zokonzera.
Kutuluka kwa mafuta kuchokera ku valve yobwerera:
Kutuluka kwa mafuta kuchokera ku valve yobwerera ndi chimodzi mwa zolakwika zomwe zimachitika nthawi zambiri chifukwa cha ukalamba kapena kuwonongeka kwa zisindikizo. Kukonza njira: Choyamba, onani ngati chisindikizo chawonongeka. Ngati chawonongeka, sinthani chisindikizocho. Komanso, inunso muyenera kufufuza ngati ulusi mawonekedwe ndi lotayirira. Ngati ndi lotayirira, liyenera kuyimitsidwanso.
Valve yobwerera yatsekedwa:
Vavu yobwerera imatha kutsekeka, zomwe zimapangitsa kuti madzi aziyenda mosiyanasiyana. Zomwe zimayambitsa kutsekeka nthawi zambiri zimakhala chifukwa cha zonyansa kapena tinthu tating'onoting'ono tomwe timalowa mu dongosolo lomwe limalumikizidwa ndi orifice kapena pachimake cha valve yobwerera. Njira yokonza: Choyamba, muyenera kuchotsa zonyansa ndi tinthu tating'onoting'ono kuchokera pachimake cha valve ndi mpando wa valve. Mutha kugwiritsa ntchito zoyeretsa ndi maburashi kuti muwayeretse. Kuphatikiza apo, zosefera zitha kuyikidwa kuti ziletse zowononga kulowa mudongosolo.
Vavu yobwerera siyingayambike:
Valavu yobwerera imatha kulephera kuyamba pakagwiritsidwa ntchito, nthawi zambiri chifukwa cha kulephera kwa dera kapena kuwonongeka kwa ma electromagnet. Kukonza njira: Choyamba, muyenera kuyang'ana ngati chingwe chamagetsi chikugwirizana bwino. Ngati kulumikizana kuli kolakwika, muyenera kulumikizanso. Kuphatikiza apo, momwe ma electromagnet amagwirira ntchito ayenera kuyang'aniridwa. Ngati electromagnet yawonongeka, iyenera kusinthidwa.
