Ithini indima ye-excavator Idler?

Ithini indima ye-excavator Idler?

1- Umfutho wepompo oyinhloko uphansi
I-excavator ye-PC200-6 isebenzisa iphampu ye-piston eguquguqukayo ephindwe kabili yohlobo lwe-axial variable.Ukugcinwa nokulungiswa kwe-Excavator Ngaphansi kwezimo ezijwayelekile, ingcindezi kawoyela ephumayo yepompo eyinhloko inkulu noma ilingana nama-MP amancane angama-30.

Uma inani lokuguga phakathi kwe-plunger yepompo eyinhloko kanye nomzimba wesilinda noma phakathi kobuso bokugcina bomzimba we-cylinder ne-valve plate lidlula izinga (igebe phakathi kwe-plunger ne-cylinder body kufanele libe ngaphansi kuka-0.02, futhi igebe phakathi kobuso bokugcina bomzimba wesilinda kanye nepuleti levalvu kufanele libe ngaphansi kuka-0.02).Indawo yokuxhumana akufanele ibe ngaphansi kuka-90%), okuzokwenza ukuthi ukucindezela okukhiphayo kwepompo enkulu kube phansi, okuzobonakala kudivayisi yokusebenza yomshini, futhi wonke umshini ngeke ukwazi ukusebenza.

2- Iqembu le-valve yokulawula ukuphuma kwepompo eliyinhloko linephutha
Ngokwesisekelo sokuthi amandla epompo eyinhloko kanye nenjini kungafaniswa ngokufanele futhi indima yenjini ingasetshenziswa ngokugcwele, ukugeleza kokuphuma kwepompo eyinhloko yomshini kuyashintsha ngokushintsha kwamandla enjini.Uma iqembu le-valve elisetshenziselwa ukulungisa ukuphuma kwephampu eyinhloko lihluleka, uma iluphu yempendulo ye-PLS ixhunyiwe, i-spool ye-valve ye-LS ibambekile, i-spool ye-PC valve ibambekile, noma ikhoyili yangaphakathi ye-P°C-EPC I-valve ye-solenoid iyashiswa Kwezinye izimo, ipompo eyinhloko izohlala isesimweni sokugeleza njalo.

Uma ipompo eyinhloko ihlala isesimweni sokugeleza okuncane, umshini uzoba buthakathaka futhi ungasheshi lapho usebenza:
Ngokufanayo, uma ipuleti le-swash, i-servo piston nezinye izingxenye zepompo eyinhloko ezilawula ngokuqondile ukuguqulwa kokugeleza kwepompo eyinhloko zibanjiwe, ukuphuma kokuphuma kwepompo enkulu ngeke kushintshe.

I-3- Ukukhishwa kwengcindezi yokulawula nge-valve yokunciphisa ingcindezi iphansi
Ngaphansi kwezimo ezijwayelekile, i-valve yokunciphisa ingcindezi yenkampani yokulungisa i-excavator e-Chongqing inganciphisa futhi izinze ukucindezela kukawoyela okukhiphayo wepompo eyinhloko ku-3.3P, yakhe ingcindezi kawoyela yokulawula.Uma i-push spool ku-valve yokunciphisa ingcindezi ingavalwanga ngokuqinile ngenxa yokuthi uwoyela ungcole kakhulu, ingcindezi yokuphuma kwevalvu yokunciphisa ukucindezela izoba ngaphansi kuka-3.3MPā.Ngalesi sikhathi, kungakhathaliseki ukuthi isibambo sokusebenza sihamba kanjani, ukucindezelwa kwamafutha okulawula kuhlala kuphansi, futhi ukunyakaza kwe-spool ye-valve yokulawula eyinhloko yemishini yokusebenza ehlukahlukene kuncane, okuholela ekugelezeni okuncane emishini yokusebenza, okuholela ekutheni ukungabi namandla kwawo wonke umshini.

I-4-Ingcindezi yokukhulula ye-valve enkulu yokusiza
Ivalvu eyinhloko yokusiza enamandla aphansi ikhawulela ukucindezela okukhulu kwalo lonke uhlelo lwe-hydraulic ku-32.5MP.Ngokucindezela okuphezulu okudlula isilinganiso, i-valve yokusiza enkulu izovuleka ukuze ikhulule ingcindezi.I-Hitachi Excavator Repair Inkampani ye-Chongqing izovikela uhlelo emonakalweni.Uma imbobo encane ku-spool ye-valve yokusiza eyinhloko ivinjiwe ngenxa yekhwalithi ephansi kawoyela futhi i-spool ngokuvamile ivulekile, noma ukucindezela okuhleliwe kwe-valve enkulu yokusiza iphansi, ingcindezi yangempela yokusiza izoba phansi, okungukuthi, uhlelo. Ingcindezi iphansi.

5- Ivalvu yokuthulula inephutha
Lapho umshayeli eqala injini futhi ebeka i-lever yokusebenza endaweni engathathi hlangothi, uwoyela we-hydraulic ophuma empompini eyinhloko ubuyela ngqo ethangini likaphethiloli ngevalvu yokuthulula, futhi ingcindezi yokukhipha ingu-3MP.Uma i-spool ye-valve yokukhipha ingavalwa ngokuqinile ngenxa yamafutha angcolile, uwoyela ophumayo wepompo eyinhloko uzodlula i-valve yokukhipha ngqo ku-tank yamafutha lapho umshini usebenza.Lapho uphawu lwe-O-ring ku-valve yokulayisha esetshenziselwa ukuvimba ukuxhumana phakathi kwamafutha okucindezela kwe-PS kanye nethangi likawoyela lonakalisiwe, kuzophinde kubangele ukuthi amafutha ompompo ompompo we-hydraulic ageleze abuyele ethangini lamafutha ngokuqondile.

I-6-LS ye-bypass valve inephutha
I-valve ye-LS bypass ingavuza ingxenye yamafutha okucindezela i-P15 kumjikelezo we-LS ngokusebenzisa izimbobo ezincane ezimbili emzimbeni we-valve (kancane) ukwandisa ukuzinza kokusebenza komshini.Uma uphawu lwe-O-ring emzimbeni we-valve lonakalisiwe, uwoyela we-PL5 wokucindezela uzoxhumana ngokuqondile nethangi likaphethiloli, okuzokwenza ngokungaqondile ukuthi i-valve yokukhipha ivuleke ngokujwayelekile, okuholela ekunyakazeni okubuthakathaka nokuhamba kancane kwedivayisi ngayinye esebenzayo.

Ngamafuphi, uma i-excavator ye-PC200-6 ingakwazi ukusebenza iyonke, ingabangelwa kakhulu izinga eliphansi likawoyela kawoyela we-hydraulic.Ngakho-ke, buyisela isici sesihlungi sikawoyela we-hydraulic ngesikhathi (esidingekayo ukuthi sishintshwe njalo ngama-500) futhi unake ukululama.
