Pali mitundu iwiri ikuluikulu ya kutayikira mu hydraulic system yama engineering engineering, kutayikira pa chisindikizo chokhazikika komanso kutayikira pa chisindikizo chosuntha. Kutayikira pa chisindikizo chokhazikika kumaphatikizapo pansi pa silinda ndi zolumikizira za chitoliro chilichonse, etc., ndipo kutayikira pa chisindikizo chosuntha makamaka kumaphatikizapo ndodo ya pisitoni ya silinda yamafuta, mavavu amitundu yambiri ndi mbali zina. Kutaya kwamafuta kungagawidwenso kutulutsa kwakunja komanso kutulutsa kwamkati. Kutuluka kwakunja kumatanthawuza kutayikira kwamafuta a hydraulic kuchokera kudongosolo kupita ku chilengedwe. Kutuluka kwamkati kumatanthawuza kusiyana kwa kuthamanga pakati pa mbali zothamanga kwambiri ndi zochepa.Chifukwa cha zifukwa monga kukhalapo ndi kulephera kwa zisindikizo, mafuta a hydraulic amayenda kuchokera kumtunda wothamanga kwambiri kupita ku mbali yotsika kwambiri mkati mwa dongosolo.

Zifukwa zomwe zimakhudza kutayikira:

1) Zomangamanga:

(1) Kusankhidwa kwa zisindikizo Kudalirika kwa ma hydraulic system kumadalira pamlingo waukulu Ponena za mapangidwe a zisindikizo za hydraulic system ndi kusankha kwa zisindikizo, chifukwa cha kusankhidwa kosayenera kwa zosindikizira mu mapangidwe ndi kusankha kwa zisindikizo zomwe sizimatero. kukumana ndi miyezo, mtundu wogwirizana, mikhalidwe yolemetsa, komanso kukakamizidwa kotheratu kwamafuta a hydraulic ndi zida zosindikizira sizinaganizidwe pakupanga. , liwiro la ntchito, kusintha kwa kutentha kozungulira, etc. Zonsezi mwachindunji kapena mosalunjika zimayambitsa kutayikira kwa hydraulic system ku madigiri osiyanasiyana. Kuphatikiza apo, popeza malo omwe makina omanga amagwiritsidwira ntchito amakhala ndi fumbi ndi zonyansa, zisindikizo zoyenera zoteteza fumbi ziyenera kusankhidwa pamapangidwewo. , kuteteza fumbi ndi dothi lina kuti lisalowe m'dongosolo kuti liwononge chisindikizo ndikuipitsa mafuta, motero kumayambitsa kutayikira.

(2) Zifukwa zina zopangira: Kulondola kwa geometric ndi kuuma kwa malo osunthira sikukwanira mokwanira pamapangidwewo, ndipo mphamvu yazigawo zolumikizira sizimayesedwa pakupanga. Nyukiliya, ndi zina zotero, zomwe zingayambitse kutayikira panthawi yogwiritsira ntchito makina.

2) Zinthu zopanga ndi kuphatikiza

(1) Zinthu zopangira: Zigawo zonse za hydraulic ndi kusindikiza zigawo zimakhala ndi zololera zokhwima, chithandizo chapamwamba, mapeto a pamwamba ndi kulekerera kwa geometric, etc. Zofunikira. Ngati kupatukana sikulolerana panthawi yopanga, mwachitsanzo: pisitoni yozungulira ya silinda, kuya kapena m'lifupi mwa phula losindikizira, kukula kwa dzenje loyika mphete yosindikizira sikuloledwa, kapena kwatuluka. zozungulira chifukwa cha zovuta zokonza, pali ma burrs kapena ma depressions, chrome plating ikutha, etc. kapena osaphatikizika, kupangitsa kuti itaya ntchito yake yosindikiza.Gawo lokhalo lidzakhala ndi malo obadwa nawo, ndipo kutayikira kudzachitika pambuyo pa msonkhano kapena pakagwiritsidwa ntchito.

(2) Zinthu za Msonkhano: Kuchita mwankhanza kwa zigawo za hydraulic ziyenera kupewedwa panthawi ya msonkhano. Mphamvu yochulukirapo idzayambitsa mapindikidwe a zigawozo, makamaka kugwiritsa ntchito ndodo zamkuwa kugunda chipika cha silinda, kusindikiza flange, ndi zina zotero; Zigawo ziyenera kufufuzidwa mosamala musanakonze, ndipo mbali zina ziyenera kufufuzidwa mosamala pa msonkhano. Ikani zigawozo mu mafuta ochepa a hydraulic ndikuzisindikiza mofatsa. Gwiritsani ntchito dizilo poyeretsa, makamaka zigawo za labala monga mphete zosindikizira, mphete za fumbi, ndi mphete za О. Ngati mugwiritsa ntchito petulo, amakalamba mosavuta ndikutaya kukhazikika kwawo koyambirira, motero amataya ntchito yawo yosindikiza. .

3) Kuwonongeka kwamafuta ndi kuwonongeka kwa magawo

(1) Kuipitsa mpweya. Pansi pa mphamvu ya mumlengalenga, pafupifupi 10% ya mpweya imatha kusungunuka mumafuta a hydraulic. Pansi pa kupanikizika kwakukulu kwa hydraulic system, mpweya wochuluka udzasungunuka mu mafuta. Mpweya kapena gasi. Mpweya umapanga thovu mu mafuta. Ngati kupanikizika kwa chithandizo cha hydraulic kumasintha mofulumira pakati pa kuthamanga kwapamwamba ndi kutsika kwa nthawi yochepa kwambiri panthawi yogwira ntchito, ming'oma imapanga kutentha kwakukulu pambali yothamanga kwambiri ndikuphulika kumbali yotsika. Ngati Pakakhala maenje ndi kuwonongeka pamwamba pa zigawo za hydraulic system, mafuta a hydraulic amathamangira pamwamba pa zigawozo pa liwiro lalikulu kuti afulumizitse kuvala kwa pamwamba, kuchititsa kutuluka.

(2) Kuwonongeka kwa tinthu Masilinda a Hydraulic ndiye zigawo zazikulu zamakina ena opangira makina a hydraulic. Chifukwa cha ntchito Panthawiyi, ndodo ya pisitoni imawululidwa ndikukhudzana mwachindunji ndi chilengedwe. Ngakhale manja otsogolera ali ndi mphete zafumbi ndi zisindikizo, fumbi ndi dothi zidzabweretsedwa mu hydraulic system, kufulumizitsa zokopa ndi kuwonongeka kwa zisindikizo, ndodo ya piston, ndi zina zotero. zinthu zothamanga kwambiri zomwe zimawononga ma hydraulic components.

(3) Kuwonongeka kwa madzi Chifukwa cha mphamvu ya zinthu monga malo ogwirira ntchito, madzi amatha kulowa mu hydraulic system, ndipo madzi amatha kuchitapo kanthu ndi mafuta a hydraulic kupanga asidi Zinthu ndi matope amachepetsa kutsekemera kwamafuta a hydraulic ndikufulumizitsa kuvala. za zigawo. Madzi amathanso kuchititsa kuti tsinde la valve yolamulira kumamatira, zomwe zimapangitsa kuti zikhale zovuta kugwiritsa ntchito valve yolamulira, kukanda chisindikizo, ndikuyambitsa kutuluka.

(4) Kuwonongeka kwa magawo kumachitika chifukwa cha kukana kwamafuta. Zopangidwa ndi mphira ndi zipangizo zina, kukalamba, kusweka, kuwonongeka, etc. Ngati ziwalozo zawonongeka chifukwa cha kugundana panthawi ya ntchito, zinthu zosindikizira zidzakandidwa, zomwe zimayambitsa kutuluka. Kodi nditani? Main Leakage Prevention and Control Countermeasures Zomwe zimayambitsa kutayikira kwa ma hydraulic system yamakina omanga ndichifukwa chakukhudzidwa kwathunthu ndi mbali zambiri. Ndi ukadaulo ndi zida zomwe zilipo, ndizovuta kuthetsa kutayikira kwa ma hydraulic system.

Pokhapokha pazikoka zomwe zili pamwambazi Kuyambira pazomwe zimatuluka mu hydraulic system, njira zoyenera ziyenera kuchitidwa kuti muchepetse kutulutsa kwa hydraulic system momwe mungathere. Pakupanga ndi kukonza maulalo, zinthu zofunika zomwe zikukhudza kutayikira ziyenera kuganiziridwa mokwanira pakupanga ndi kukonza kwa groove yosindikiza.Kuphatikiza apo, kusankha zisindikizo ndikofunikanso kwambiri. Ngati Kulephera kuganizira mozama zinthu zomwe zimayambitsa kutayikira koyambirira kungayambitse kutayika kosawerengeka pakupanga kwamtsogolo. Sankhani njira zoyenera zolumikizirana ndi kukonza ndikuphunzira kuchokera pazomwe zidachitika kale. Mwachitsanzo, yesetsani kugwiritsa ntchito zida zapadera posonkhanitsa mphete zosindikizira, ndipo Ikani mafuta pa mphete yosindikiza.

Pankhani ya kuwongolera kuwononga mafuta a hydraulic, tiyenera kuyambira kugwero la kuipitsidwa, kulimbikitsa kuwongolera komwe kumachokera kuipitsidwa, ndikutenga njira zosefera zogwira mtima komanso kuwunika pafupipafupi kwamafuta. Pofuna kuthetsa bwino zinthu zakunja (Madzi, fumbi, particles, etc.) kuipitsidwa kwa silinda ya hydraulic, njira zina zotetezera zikhoza kuwonjezeredwa. Mwachidule, kupewa ndi kuwongolera kutayikira kuyenera kukhala kokwanira komanso kulingalira kokwanira kuti kutheke.
