Hydraulic balance valve Excavator hydraulic cylinder valve core RPEE-LBN

Zvikanganiso zvakajairika zvevhavha yekuyamura ndezvi: vibration uye ruzha; Kugadzirisa kudzvinyirira kwakaderera, kugadzirisa hakubatsiri; Kudzvinyirira kwekugadzirisa kwakakwirira, kugadzirisa hakubatsiri; Pressure fluctuation; Mavuza, nezvimwewo. Zvikonzero zvekutadza uye nzira dzekugadzirisa dambudziko ndezvizvi:

1. Vibration uye ruzha

1) Ruzha rwemvura runofanira kutorwa maererano nezvikonzero zvinotevera:

(1) Cavitation cavitation ruzha uye eddy ikozvino uye shear fluid ruzha mushure mevhavha yekufashukira inofanira kutsiviwa;

(2) Mhepo inonzwika yemhepo yekumanikidza panguva yekuburitsa kwevhavha yekuyamura inofanira kuwedzera nguva yekuburitsa, uye ruzha rwepamusoro-ruzha runokonzerwa nekusaenzana kugoverwa kwekumanikidza muvhavhavha yekutyaira uye main slide valve inofanira kuvandudza geometric accuracy. yevhavha, wedzera dhayamita yepombi yemafuta ekudzoka, sarudza chitubu chevharuvhu yakapfava uye viscosity yakakodzera yepombi yekudzorera mafuta nemhepo, inofanira kutarisa chisimbiso uye kupera. Kana iyo yekudzokera kumashure mupombi yemafuta yekudzoka yakakura kwazvo, iyo yekudzoka pombi yemafuta dhayamita inofanira kuwedzerwa uye pombi yemafuta ekudzoka inofanira kuiswa zvakasiyana.

(3) Ivhavha yekudzivirira mukati mekudzivirira nzvimbo yekudzivirira mumhepo, inofanira kutarisa chisimbiso uye kupera kwemhepo kunodarika kukosha kunobvumirwa, inofanira kusarudzwa kuti ienderane nekuyerera kwevhavha yekuyamura.

2) Mechanical ruzha, matanho anoenderana anofanirwa kutorwa maererano nezvikonzero zvinotevera:

Iyo slide valve uye gomba revharuvhu rakanyanya kusimba kana kusununguka zvakanyanya kuti rikonzere kudedera uye ruzha, inofanirwa kutarisa nekugadzirisa kudzvanywa kwekudzora chitubu chakanyanya kupfava kana kuremara kuburitsa ruzha, inofanira kutsiva kudzvanywa kunodzora chitubu.

Kana iyo inodzvinyirira inodzora nut yakasununguka, inofanira kusimbiswa uye taper valve inofanira kunge yasakara, inofanira kugadziriswa nenguva kuti ibudise resonance ruzha nezvimwe zvikamu zvegadziriro, uye inofanira kugadziriswa munguva yekubvisa resonance.
