Amavuta ya Hydraulic isuku ihinduka

Uburyo bwa servo muri sisitemu ya hydraulic irasobanutse neza (clearance rusange ni 3μm), ihagarikwa byoroshye nuduce duto twa peteroli, biganisha ku kunanirwa kugenzura.Ibice byamavuta yo gusiga bizihutisha kwambara kashe muri sisitemu, bityo bigabanye kwizerwa nubuzima bwa serivisi bwibikoresho.Niyo mpamvu, birakenewe gupima isuku yibikomoka kuri peteroli muburyo nyabwo, aribyo bita "isuku".

Kugeza ubu, ISO 4406 na NAS 1638 zikoreshwa cyane mu kwerekana isuku y’amavuta.Hariho inzandiko runaka hagati yibi bipimo byombi.Ubushinwa buhwanye bwakoresheje ISO 4406-1999, bwashyizeho "hydraulic yohereza amavuta akomeye y’imyanda ihumanya" GB / T 14039-2002.

Igipimo cya ISO 4406-1999 ni ukumenya umubare wibice> 4μm,> 6μm,> 14μm muri 100ml yamavuta, igipimo cy’isuku ISO 4406 cyatanzwe n’umuryango mpuzamahanga ushinzwe ubuziranenge mu 1991 kugira ngo harebwe kodegisi y’umwanda (isuku) .

ISO 4406 yatoranijwe kuri 5μm, 15μm ingano zombi, kubera ko ubushakashatsi bwerekanye ko 5μm ibice bizatera kwambara cyane, kandi> 15μm ibice bizatera hydraulic ibice, bityo rero ubunini bwombi bushobora kwerekana cyane cyane kwambara amavuta, ibintu byifashe neza.

Nigute ushobora guhindura isuku ya hydraulic isuku mubipimo bitandukanye?Imbonerahamwe ikurikira irerekana uburyo bwo guhindura hagati ya ISO4406 kumeza yisuku nibipimo bitandukanye:

Imbonerahamwe iri muri iki gitabo yemerera abakoresha gukoresha ibyuma byikora byikora kugirango baboneisano hagati yibice bito bibarwa mubunini butandukanye hamwe nimibare yo gutanga raporo yaibipimo bitandukanye byanduye.

Menya ko amwe mumeza yanditswe asobanurwa nkumubare wuzuye (urugero “> 6µm”) naabandi basobanuwe nkibara ritandukanye (urugero 6–14µm ”).

Ingero zingana zingana zitangwa nka "µm" bivuga ACFTD (ni ukuvuga umukungugu mwiza wo mu kirere)kugabura.Ingero zingana zingana zitangwa nka "µm (c)" bivuga MTD (ni ukuvuga Ikizamini cya ISO HagatiUmukungugu).

Ibipimo byose biri mububiko, kandi bitanga uburyo bworoshye bwo guhindura ibiceibara imipaka yoroshye gusobanura.Mugushakisha ibisabwa mubisanzwe,

ibara ryibice rishobora guhindurwa neza kurwego rwanduye.

NAS1638

Igipimo cy’isuku NAS 1638 cyateguwe kubice byo mu kirere muri Amerika kandiiracyakoreshwa cyane mubikorwa byinganda nindege zo mu kirere.

Imibare iratandukanye, kandi NAS icyiciro gikunze kuvugwa nkishusho imweKugereranya ntarengwa byemewe byemewe (urugero ni bibi cyane) kubintu byagenweingano.
