Excavator hayidiroliki mpope mafuta okwanira, kuthamanga sangathe kuwuka bwanji?

Pampu ya hydraulic ndi chipangizo champhamvu cha chofukula cha hydraulic system, chomwe chimasintha mphamvu yamakina agalimoto kukhala mphamvu ya hydraulic ndi zotuluka zotuluka ndi kukakamiza, ndipo imakhala ndi malo ofunikira kwambiri mu hydraulic system. Ngati pampu ya hydraulic ikalephera, imakhudza ntchito yanthawi zonse ya hydraulic system. Nkhaniyi imafotokoza makamaka za excavator hydraulic pump kulephera ndi njira zothetsera mavuto.

Kupanikizika sikukwera

Chifukwa 1: mpope si pa mafuta kapena osakwanira otaya.

Chothandizira: Dzazani mpope ndi mafuta ogwira ntchito.

Chifukwa 2: Kuthamanga kwa valve yotsitsimutsa ndikotsika kwambiri kapena kulephera.

Chothandizira: Sinthaninso kupanikizika kwa valve yothandizira kapena kukonza valavu yothandizira.

Chifukwa 3: Kutayikira mu dongosolo.

Chothandizira: Yang'anani dongosolo, konzani malo otayira.

Chifukwa 4: Zomangira zotchingira pampu zimamasulidwa chifukwa cha kugwedezeka kwa pampu yamafuta yomwe imagwira ntchito kwa nthawi yayitali.

Kuchiza: Limbani zomangira bwino.

Chifukwa 5: Kutuluka kwa mpweya mu chitoliro choyamwa.

Njira yochotsera: yang'anani maulalo, ndikusindikizidwa ndikumangika.

Chifukwa 6: Kusakwanira kuyamwa mafuta.

Chothandizira: Dzazani mpope ndi mafuta ogwirira ntchito.

Chifukwa 7: Kusintha kosayenera kwa kuponderezedwa kwapope kosinthika.

Kuchiza: Sinthaninso kukakamiza kofunikira.

Mafuta a pampu ya Hydraulic ndi osakwanira

Kuthetsa Mavuto: Mpweya wakunja umalowa m'chipinda chogwirira ntchito cha pampu ya pistoni zomwe zimapangitsa kuti anthu asamuke.

Kusanthula Kulephera: Chifukwa cha malo ovuta ogwirira ntchito ofukula, ndizosavuta kuti pampu ya pisitoni iphwanyire chitoliro choyamwa kapena doko loyamwa silimasindikizidwa bwino, zomwe zimapangitsa kuti pampu iyambe kuyamwa mpweya. Pulunger mpope mu ntchito, ngati mafuta mu plunger ntchito chipinda mu mlengalenga, ndiye pamene plunger ali pamalo a kuthamanga doko, plunger adzakhala pressurize mafuta ndi mpweya mu chipinda.

Pamene plunger ikupita pansi pa dzenje la silinda, nthawi zonse padzakhala gawo la voliyumu yotsalira pansi, mwachitsanzo, gawo la mafuta oponderezedwa limasungidwa mu voliyumu yotsala ya patsekeke. Pamene plunger ikupitiriza kuthamangira ku doko loyamwa, ndi kuwonjezeka kwa voliyumu yazitsulo, mphamvu yamkati yamafuta imachepetsedwa, mpweya wotsekedwa mu voliyumu yotsalayo umakulitsidwa, kotero kuti gawo la gawo logwira ntchito lidzatengedwa ndi gawo ili. mpweya, kotero kuti mphamvu yeniyeni yoyamwa ya pampu ya pisitoni imachepetsedwa. Mpweya wamadzimadzi ukafika pamlingo wina, umapangitsa kuti makinawo azipereka mafuta osakwanira kapena osapereka mafuta. Komanso, ngati mafuta hayidiroliki sangathe kuyenda mu doko suction mu nthawi, pampu kuyamwa adzatulutsa matumba mpweya, motero kuwononga msanga chisindikizo ndi plunger yamphamvu khoma cavitation ndi zina zolephera zochitika. Chifukwa chake, njira ziyenera kuchitidwa kuti muchepetse kapena kuchotsa mpweya mu hydraulic system.

Njira zochotsera:

1. Onetsetsani kuti palibe kutayikira konse. Kuti atsimikizire kuti asindikizidwa bwino, zolumikizira zonse za mapaipi ziyenera kulumikizidwa; kwa mapampu a pistoni, ayenera kukhala ndi chipangizo chosindikizira cholimba.

2. Pewani payipi yoyamwa kuti isaduke kapena kuyamwa mopanda phokoso. Yesetsani kuwongolera kuchuluka kwa madzi pa doko loyamwa kuti muteteze kukakamiza pagawo lililonse la mzere woyamwa kukhala wotsika kuposa kuthamanga kwa mumlengalenga ndikupanga vacuum, zomwe zimapangitsa kuti payipi ya rabara itayike, kuyamwa flattening ndi kulowerera kwa mpweya.

3. Onetsetsani kutalika kwa mafuta a tanka ya mafuta. Kawirikawiri mlingo wotsikitsitsa wa thanki yamafuta ndi doko loyamwa la mtunda woyimirira uyenera kukhala wosakwana 0.5m; ngati dongosololo lilola, kutalika kwa mulingo wamafuta mu thanki kuyenera kukhala kokulirapo kuposa doko loyamwa la mpope, ndikuti kutha kwa hydraulic system kubwerera ku chitoliro chamafuta nthawi zambiri kumakhala mulingo wamafuta pansipa, kuti pewani kupanga thovu la mpweya.

4. Ngati mu thanki pali thovu zambiri za mpweya, ziyenera kuchotsedwa panthawi yake. Ngati pali mpweya wochuluka m'madzimadzi, choyikapo paipi ya pisitoni chikhoza kumasulidwa kuti chitulutse mpweya wa mpope.
