kuyang'ana kowoneka
Pa zolakwika zina zosavuta, zigawo ndi zigawo zimatha kuyang'aniridwa ndi maso, chitsanzo cha manja, kumva ndi kununkhiza.Kukonza kapena kusintha zowonjezera;gwirani chitoliro cha mafuta (makamaka chitoliro cha rabara) ndi dzanja, pamene mafuta akuthamanga akuyenda, padzakhala kugwedezeka, koma sipadzakhalanso chodabwitsa chotero pamene palibe mafuta akuyenda kapena kupanikizika kuli kochepa kwambiri.
Kuphatikiza apo, kukhudza pamanja kungagwiritsidwenso ntchito kuweruza ngati mafuta opangira ma hydraulic okhala ndi zida zamakina opatsirana ndi abwino.Imvani kutentha kwa chipolopolo cha chigawocho ndi manja anu.Ngati chipolopolo cha chigawocho chatenthedwa, zikutanthauza kuti mafutawo ndi osauka;kumva kungathe kuweruza mbali zamakina Digiri yolakwika ndi kuwonongeka komwe kumachitika chifukwa cha kuwonongeka, monga kuyamwa pampu ya hydraulic, kutsegulidwa kwa ma valve osefukira, chigawo cha makadi ndi zolakwika zina zimapanga phokoso lachilendo monga momwe madzi amakhudzira kapena "nyundo yamadzi";mbali zina zidzaonongeka chifukwa cha kutenthedwa, mafuta osauka ndi cavitation.Ngati pali fungo lachilendo chifukwa cha zifukwa zina, vutolo likhoza kuweruzidwa ndi kununkhiza.
kusinthana diagnostics
Ngati palibe chida chodziwira matenda pamalo okonzerako kapena zigawo zomwe ziyenera kuyang'aniridwa zili zolondola kwambiri kuti zisasweka, njirayi iyenera kugwiritsidwa ntchito kuchotsa zinthu zomwe zikuganiziridwa kuti ndi zolakwika ndikuyika zatsopano kapena zigawo zachitsanzo zomwe zimagwira ntchito. kawirikawiri pamakina ena oyesera.Kuzindikira kungapangidwe ngati cholakwikacho chitha kuthetsedwa.
Zingakhale zovuta kuyang'ana cholakwika ndi njira yodziwira matenda, ngakhale kuti imachepetsedwa ndi kapangidwe kake, kusungirako chigawo chapamalo kapena kusokoneza kosautsa, ndi zina zotero, koma kwa ma valve ang'onoang'ono komanso osavuta kugwiritsa ntchito monga ma valve balance, kusefukira. ma valve, ndi ma valve a njira imodzi Ndikosavuta kugwiritsa ntchito njira iyi kuti muwononge zigawozo.Njira yowunikira m'malo imatha kupewa kuwonongeka kwa magwiridwe antchito a zigawo za hydraulic zomwe zimayambitsidwa ndi kusawona bwino.Ngati zolakwa zomwe tazitchula pamwambapa sizikuyang'aniridwa ndi njira yowonjezera, koma valavu yaikulu yokayikitsa yotetezera imachotsedwa mwachindunji ndikuphwanyidwa, ngati palibe vuto ndi chigawocho, ntchito yake ingakhudzidwe pambuyo pobwezeretsanso.
Njira yoyendera mita
Kuweruza zolakwika za dongosololi poyesa kuthamanga, kuyenda ndi kutentha kwa mafuta a mafuta a hydraulic mu gawo lililonse la hydraulic system.Ndizovuta kwambiri, ndipo kukula kwa kayendedwe kake kakhoza kuweruzidwa mwachisawawa ndi liwiro la machitidwe a actuator.Choncho, pozindikira pa malo, njira zambiri zodziwira kupanikizika kwadongosolo zimagwiritsidwa ntchito.
Kulephera, kofala kwambiri ndikutaya kwa hydraulic pressure.Ngati ipezeka kuti ndi vuto la silinda ya hydraulic, itha kukonzedwanso:
Nthawi zambiri, kutayikira kwa ma silinda a hydraulic kumagawidwa m'mitundu iwiri: kutulutsa kwamkati ndi kutuluka kwakunja.Malingana ngati tiyang'anitsitsa mosamala, tikhoza kuweruza chifukwa cha kutuluka kwa kunja.Zimakhala zovuta kuweruza chifukwa cha kutayikira kwamkati kwa silinda ya hydraulic, chifukwa sitingathe kuwona mwachindunji kutuluka kwamkati.
Chimodzi, kutuluka kunja.
1. Kuwonongeka kwa chisindikizo pakati pa nsonga yotalikirapo ya pisitoni ndi ndodo ya pisitoni kumachitika makamaka chifukwa cha kukhwinyata kwa silinda ya pistoni, komanso kumabwera chifukwa cha ukalamba.
2. Chisindikizo pakati pa kumapeto kwa pisitoni ndodo ndi cylinder liner yawonongeka.Izi zimachitika makamaka chifukwa cha kukalamba kwa chisindikizo pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali.Palinso zochitika zambiri zomwe chisindikizocho chimafinyidwa ndikuwonongeka ndi mphamvu yochulukirapo pamene chivundikiro chapamwamba chimagwiritsidwa ntchito.Palinso masilinda a hydraulic opangidwa ku China.Mapangidwe a wopangayo ndi osamveka, ndipo nthawi zambiri, wopanga amasunga ndalama.
3. Kung'ambika kwa mapaipi olowera ndi kutulutsa mafuta a silinda yamafuta kumapangitsanso kutayikira kwa silinda yamafuta a hydraulic.
4. Kutaya kwamafuta chifukwa cha zolakwika pa phula kapena chivundikiro cha silinda.
5. Ndodo ya pisitoni imakoka ndipo imakhala ndi ma grooves, maenje, ndi zina zotero.
6. Kuwonongeka kwa mafuta odzola kumapangitsa kutentha kwa silinda yamafuta kukwera molakwika, zomwe zimalimbikitsa kukalamba kwa mphete yosindikiza.
7. Kutaya kwa mafuta chifukwa cha kugwiritsidwa ntchito pafupipafupi kupitirira kupanikizika kwa silinda.
Awiri, kutayikira mkati.
1. Mphete yosamva kuvala pa pisitoni imavalidwa kwambiri, kuchititsa kukangana pakati pa pisitoni ndi cylinder liner, ndipo potsirizira pake kumangiriza cylinder liner, pistoni ndi chisindikizo.
2. Chisindikizocho chimalephera kugwiritsidwa ntchito kwa nthawi yaitali, ndipo chisindikizo cha pisitoni (makamaka U, V, Y-rings, etc.) chikukalamba.
3. Mafuta a hydraulic ndi onyansa, ndipo zonyansa zambiri zimalowa mu silinda ndi kuvala chisindikizo cha pisitoni mpaka kuwonongeka, kawirikawiri zojambula zachitsulo kapena zinthu zina zakunja.
3. Nkhani zofunika kuziganizira pakugwiritsa ntchito ma silinda a hydraulic.
1. Pogwiritsa ntchito nthawi zonse, tiyenera kusamala kuti titeteze kunja kwa ndodo ya pistoni kuti tipewe kuwonongeka kwa chisindikizo kuchokera ku tokhala ndi zokopa.Tsopano masilinda a makina omangira amapangidwa ndi mbale zoteteza.Ngakhale zilipo, tifunikabe kusamala kuti tipewe kuphulika ndi kukwapula.zokandwa.Kuphatikiza apo, ndiyeneranso kuyeretsa matope ndi mchenga pafupipafupi pamphete yosindikizira yopanda fumbi ya silinda ndi ndodo ya pisitoni yowonekera kuti muteteze dothi lovuta kuyeretsa lomwe limayikidwa pamwamba pa ndodo ya pistoni kuti lisalowe mkati. ya silinda, zomwe zingapangitse kuti pisitoni, silinda kapena chisindikizo chiwonongeke.kuwonongeka.
2. Panthawi yogwiritsira ntchito bwino, tiyeneranso kusamala kuti tiyang'ane pafupipafupi zigawo zogwirizanitsa monga ulusi ndi ma bolts, ndikuzimanga nthawi yomweyo ngati zapezeka kuti zamasuka.Chifukwa kumasuka kwa malowa kudzachititsanso kuti mafuta a hydraulic cylinder atayike, omwe amamveka bwino ndi omwe amagwira ntchito yomanga.
3. Nthawi zonse muzipaka mbali zogwirizanitsa kuti muteteze dzimbiri kapena kuvala kwachilendo m'malo opanda mafuta.Tiyeneranso kutchera khutu.Makamaka mbali zina zokhala ndi dzimbiri, tiyenera kuthana nazo munthawi yake kuti tipewe kutayikira kwamafuta a hydraulic cylinders chifukwa cha dzimbiri.
4. Panthawi yokonza bwino, tiyenera kumvetsera nthawi zonse m'malo mwa mafuta a hydraulic ndi kuyeretsa panthawi yake fyuluta yamagetsi kuti titsimikizire ukhondo wa mafuta a hydraulic, omwe ndi ofunika kwambiri kuti apititse patsogolo moyo wautumiki wa ma hydraulic cylinders.
5. Pa ntchito yachibadwa, tiyenera kulabadira kulamulira kutentha dongosolo, chifukwa kwambiri kutentha mafuta kuchepetsa moyo utumiki wa chisindikizo, ndi kwa nthawi yaitali kutentha mafuta kuchititsa mapindikidwe okhazikika chisindikizo, ndipo mu milandu kwambiri, chisindikizo chidzalephera.
6. Kawirikawiri, nthawi iliyonse yomwe timagwiritsa ntchito, tifunika kuyendetsa mayesero owonjezera ndi kubweza kwathunthu kwa zikwapu za 3-5 musanayambe kugwira ntchito.Cholinga chochitira izi ndikutulutsa mpweya m'dongosolo ndikuwotcha dongosolo lililonse, kuti mupewe kukhalapo kwa mpweya kapena madzi mu dongosolo, zomwe zimapangitsa kuphulika kwa mpweya mu thupi la cylinder, zomwe zingawononge zisindikizo ndikuyambitsa kutulutsa mkati. ya silinda, etc. Cholakwa.
7. Ntchito iliyonse ikamalizidwa, tiyenera kusamala kuti tisunge zida zazikulu ndi zazing'ono ndi zidebe pamalo abwino, ndiko kuti, kuonetsetsa kuti mafuta onse a hydraulic mu hydraulic cylinder amabwerera ku tanki yamafuta a hydraulic kuti atsimikizire. kuti silinda ya hydraulic sipanikizidwa.Chifukwa silinda ya hydraulic ili pansi pamavuto kunjira imodzi kwa nthawi yayitali, imayambitsanso kuwonongeka kwa chisindikizo.
