Nge-R225-7 i-valve yokusiza i-excavator 31N6-17400 yokulayisha impahla

I-valve yokusiza ayikwazi ukudlala indima ye-valve yokuphepha kuphela, kodwa futhi ingasetshenziswa njenge-valve yokulawula ingcindezi, i-valve yokukhulula, i-valve yokucindezela emuva, i-valve yebhalansi nokunye.Okulandelayo ukwethulwa okuningiliziwe kwemisebenzi eyisikhombisa yevalvu yokukhulula ohlelweni lwe-hydraulic.

1. Umphumela wokuchichima
Lapho iphampu yobuningi isetshenziselwa ukunikezwa kukawoyela, ifaniswa ne-throttle valve ukulungisa nokulinganisela ukugeleza ohlelweni lwe-hydraulic.Kulesi simo, i-valve ivame ukuvuleka ngokushintshashintsha kwengcindezi, futhi amafutha ageleza abuyele ethangini ngokusebenzisa i-valve, edlala indima yokuchichima ngaphansi kwengcindezi eqhubekayo.

2. Dlala indima yokuvikela ukuphepha

Gwema izingozi ezibangelwa ukugcwala ngokweqile kohlelo lwe-hydraulic kanye nethuluzi lomshini.Kulesi simo, i-valve ivame ukuvalwa, kuphela lapho umthwalo udlula umkhawulo obekiwe wokuvula, udlale indima yokuvikela ukuphepha.Ngokuvamile, ingcindezi yokubeka i-valve yokusiza ilungiswa ngo-10 ~ 20% ngaphezu kokucindezela okukhulu kokusebenza kwesistimu.

3. Isetshenziswa njengevalve yokuthulula

I-valve yokusiza umshayeli kanye ne-valve ye-solenoid enezinhlangothi ezimbili ingasetshenziswa ndawonye ukuze kuthululwe uhlelo.

4. Ukuze uthole i-valve elawula ingcindezi elawulwa kude

Imbobo yesilawuli kude se-valve yokukhulula ixhunywe endaweni yokungena ye-remote control valve okulula ukuyilungisa, ukuze kufezeke injongo yesilawuli kude.

5. Ukulawula isiteji esikhulu nesiphansi

Sebenzisa i-valve ehlehlayo ukuze uxhume imbobo yesilawuli kude sevalvu yokukhulula enokulawula okuningana kwengcindezi yesilawuli kude ukuze ufinyelele ukulawula kwamaleveli amaningi aphezulu naphansi.

6. Isetshenziswa njenge-valve yokulandelana

Imbobo yokubuyisela uwoyela ye-valve yokusiza umshayeli iyashintshwa ibe indawo yokukhipha uwoyela wokucindezela okukhiphayo, futhi isiteshi sokubuya kukawoyela sasekuqaleni siyavinjwa ngemuva kokuthi ingcindezi iphushwe ivule i-valve eyi-conical, ukuze imbobo yokudonsa uwoyela ephinde yacutshungulwa ingakwazi. ageleze abuyele ethangini, ukuze asetshenziswe njenge-valve yokulandelana.

7. Isetshenziselwa ukukhiqiza ingcindezi emuva
I-valve yokukhulula ixhunywe ochungechungeni kumjikelezo kawoyela obuyayo ukuze ikhiqize ingcindezi yangemuva futhi ilinganise ukunyakaza kwe-actuator.Ngalesi sikhathi, ukucindezelwa kokumiswa kwe-valve yokusiza kuphansi, futhi i-valve esebenza ngokuqondile yokunciphisa ukucindezela ivame ukusetshenziswa.
