Momwe mungapewere cavitation mu hydraulic system?

Mu hydraulic system, cavitation ndizochitika zomwe kusintha kwachangu kwa mafuta kumapangitsa kupanga mapangidwe ang'onoang'ono odzaza nthunzi m'malo omwe kupanikizika kumakhala kochepa.Kuthamanga kukatsika mpaka pansi pa mlingo wa saturated-nvapo pa kutentha kwa mafuta, mabowo angapo odzadza ndi nthunzi amapangidwa mwamsanga.Chotsatira chake, kuphulika kwakukulu kwa mpweya kumabweretsa kutha kwa mafuta mu chitoliro kapena ma hydraulic elements.

Chodabwitsa cha cavitation nthawi zambiri chimachitika pakhomo ndi kutuluka kwa valve ndi mpope.Mafuta akamadutsa mumsewu wocheperako wa valve, kuthamanga kwamadzimadzi kumawonjezeka ndipo kuthamanga kwamafuta kumachepa, motero cavitation imachitika.Kuphatikiza apo, chodabwitsachi chikuwoneka ngati pampu imayikidwa pamalo okwera kwambiri, kukana kuyamwa kwamafuta ndikokulirapo chifukwa m'mimba mwake mkati mwa chitoliro choyamwa ndi chochepa kwambiri, kapena kuyamwa kwamafuta sikukwanira chifukwa cha liwiro la mpope ndilapamwamba kwambiri.

Mpweya thovu, amene amadutsa mkulu kuthamanga m'dera ndi mafuta, kuswa mwamsanga chifukwa cha khama la kuthamanga, ndiyeno ozungulira madzi particles kubweza thovu pa liwilo, motero kugundana liwiro pakati pa particles umabala tsankho hayidiroliki zimakhudza.Zotsatira zake, kuthamanga ndi kutentha mwa zina kumawonjezeka kwambiri, zomwe zimapangitsa kugwedezeka ndi phokoso.

Pakhoma lozungulira lozungulira pomwe zibowo zimakhazikika komanso pamwamba pa zinthu, tinthu tating'onoting'ono tachitsulo timagwa, chifukwa cha kudwala kwanthawi yayitali ndi kukhudzidwa kwa ma hydraulic ndi kutentha kwakukulu, komanso kuwononga kwambiri mphamvu chifukwa cha gasi wamafuta.

Pambuyo pofotokoza zochitika za cavitation ndi zotsatira zake zoipa, ndife okondwa kugawana nzeru zathu ndi zomwe takumana nazo za momwe tingapewere kuti zisachitike.

【1】Chepetsani kutsika kwamphamvu pamalo omwe mukuyenda m'mabowo ang'onoang'ono ndi ma interspaces: kuchuluka kwa kuthamanga komwe kumayembekezeredwa kumabowo ndi pambuyo pake ndi p1/p2 <3.50.
【2】Tanthauzirani kukula kwa chitoliro cha hydraulic pump mayamwidwe moyenera, ndikuchepetsa liwiro lamadzimadzi mkati mwa chitoliro munjira zambiri;kuchepetsa kuyamwa kwa pampu, ndikuchepetsa kuwonongeka kwamphamvu kwa chingwe cholowera momwe mungathere.
【3】Sankhani T-junction yapamwamba yotchinga mpweya ndikugwiritsa ntchito pampu yamadzi yothamanga kwambiri ngati mpope wothandizira popereka mafuta.
【4】 Yesani kutengera mapaipi onse owongoka pamakina, kupewa kutembenuka kwakuthwa ndi kung'amba pang'ono.
【5】 Kupititsa patsogolo luso lotha kukana kuyaka kwa gasi.
