Kulesi sihloko, sizokhuluma ngamaphutha ajwayelekile kumjikelezo we-hydraulic wedivayisi esebenzayo yesilayishi. Lesi sihloko sizohlukaniswa sibe izihloko ezimbili okufanele zihlaziywe.
Iphutha le-1: Ibhakede noma i-boom ayinyakazi
Ukuhlaziywa kwesizathu:
I-1) Ukwehluleka kwepompo ye-hydraulic kunganqunywa ngokulinganisa ingcindezi yokuphuma kwepompo. Izizathu ezingaba khona zihlanganisa i-shaft yepompo ukusonteka noma ukulinyazwa, ukuzungezisa ukungasebenzi kahle noma ukubhajwa, ama-bearings agqwalile noma abambekile, ukuvuza okukhulu, i-side plate edonsa kanzima noma ibe rough, njll.
2) Isihlungi sivalekile futhi kunomsindo.
3) Ipayipi lokumunca liphukile noma ipayipi elihlangene nepompo likhululekile.
4) Kunamafutha amancane kakhulu ethangini likaphethiloli.
5) Isikhala sethangi likaphethiloli sivaliwe.
I-6) I-valve yokusiza eyinhloko ku-valve yezindlela eziningi ilimele futhi ihluleka.
Indlela yokuxazulula inkinga:Hlola iphampu ye-hydraulic, thola imbangela, futhi uqede ukwehluleka kwepompo ye-hydraulic; hlanza noma shintsha isikrini sokuhlunga: hlola amapayipi, amalunga, izimbobo zethangi kanye nevalvu yokukhulula enkulu ukuze uqede iphutha.
Iphutha lesi-2: Ukuphakanyiswa kwe-Boom akunamandla
Ukuhlaziywa kwesizathu:
Isizathu esiqondile sokuphakanyiswa okubuthakathaka kwe-boom ukucindezela okunganele ekamelweni elingenanduku le-boom hydraulic cylinder. Izizathu eziyinhloko yilezi: 1) Kukhona ukuvuza okukhulu empompini ye-hydraulic noma isihlungi sivalekile, okuholela ekuletheni uwoyela okwanele ngepompo ye-hydraulic. 2) Ukuvuza okukhulu kwangaphakathi nangaphandle kwenzeka ohlelweni lwe-hydraulic.
Izimbangela zokuvuza kwangaphakathi zihlanganisa: umfutho oyinhloko we-valve yokuphepha ye-valve ehlehlisa izindlela eziningi ulungiswa uphansi kakhulu, noma umongo we-valve oyinhloko ubhajwe endaweni evulekile ngenxa yokungcola (intwasahlobo ye-valve eyinhloko ye-valve yomshayeli ithambile kakhulu futhi ivinjwa kalula ukungcola; i-boom reverse valve ku-valve yezindlela eziningi ibhajwe endaweni yokudonsa amanzi, igebe phakathi kwe-valve core kanye nembobo yomzimba likhulu kakhulu noma i-valve yendlela eyodwa ku-valve ayivalwanga ngokuqinile; indandatho yokuvala ku-boom cylinder piston yonakele noma Ukugqokwa okukhulu; umphongolo we-boom cylinder ugugile kakhulu noma ucindezelwe; igebe phakathi komgogodla we-valve yokulawula ukugeleza kanye nomzimba we-valve likhulu kakhulu; izinga lokushisa likawoyela liphezulu kakhulu.
Ukuxazulula inkinga:
1) Hlola isihlungi, sihlanze noma usishintshe uma sivalekile; hlola futhi uqede imbangela yokushisa kukawoyela ngokweqile, bese uyibuyisela esikhundleni uma uwoyela uwohloka.
2) Hlola ukuthi i-valve yokuphepha eyinhloko ibambekile yini. Uma ibhajwe, vele uhlakaze futhi uhlanze umgogodla oyinhloko we-valve ukuze ukwazi ukuhamba ngokukhululeka. Uma iphutha lingenakuqedwa, sebenzisa i-valve yokuhlehlisa enezindlela eziningi, zungezisa nati elilungisayo levalvu yokuphepha eyinhloko, bese ubheka impendulo yokucindezela kwesistimu. Uma ukucindezela kungalungiswa kunani elishiwo, iphutha liqedwa ngokuyisisekelo.
3) Hlola ukuthi indandatho yokuvala i-hydraulic cylinder piston ilahlekelwe ukusebenza kwayo kokuvala: hlehlisa isilinda se-boom phansi, bese ususa ipayipi elinomfutho ophezulu ekuhlanganyeleni kokuphuma kwe-rodless valve, futhi uqhubeke nokusebenzisa i-valve ehlehlisa i-boom ukuze ihoxise. induku ye-boom cylinder piston iqhubekela phambili. Njengoba i-piston rod isifinyelele phansi futhi ayisakwazi ukunyakaza, ukucindezela kuyaqhubeka nokukhuphuka. Bese ubheka ukuthi akhona yini amafutha aphuma endaweni yokukhipha uwoyela. Uma kuphuma amafutha amancane kuphela, kusho ukuthi indandatho yokuvala ayizange yehluleke. Uma kunokugeleza okukhulu kwamafutha (ngaphezu kuka-30mL/min), kusho ukuthi iringi yokuvala ihlulekile futhi kufanele ishintshwe.
4) Ngokusekelwe esikhathini sokusetshenziswa kwe-valve yezindlela eziningi, kungahlaziywa ukuthi ingabe igebe phakathi kwe-valve core kanye nembobo yomzimba we-valve likhulu kakhulu. Igebe elivamile lingu-0.01mm, futhi inani lomkhawulo ngesikhathi sokulungiswa lingu-0.04mm. Hlukanisa futhi uhlanze i-valve yesilayidi ukuze uqede ukunamathela.
5) Hlola igebe phakathi komgogodla wevalvu yokulawula ukugeleza kanye nembobo yomzimba wevalvu. Inani elivamile lingu-0.015 ~ 0.025mm, futhi inani eliphakeme alidluli u-0. 04mm. Uma igebe likhulu kakhulu, i-valve kufanele ishintshwe. Hlola ukuvaleka kwe-valve yendlela eyodwa kuvalvu. Uma ukuvala uphawu kungalungile, gaya isihlalo se-valve bese ushintsha i-valve core. Hlola imithombo bese uyishintsha uma ikhubazekile, ithambile noma iphukile.
I-6) Uma izimbangela ezingenhla ezingenhla ziqedwa futhi iphutha lisekhona, ipompo ye-hydraulic kumele ihlakazwe futhi ihlolwe. Ngephampu yegiya ye-CBG evame ukusetshenziswa kulo mshini, ikakhulukazi hlola imvume yokugcina iphampu, futhi okwesibili uhlole imvume ye-meshing phakathi kwamagiya amabili kanye nemvume yomsakazo phakathi kwegiya negobolondo. Uma igebe likhulu kakhulu, kusho ukuthi ukuvuza kukhulu kakhulu ngakho-ke uwoyela wokucindezela owanele awukwazi ukukhiqizwa. Ngalesi sikhathi, ipompo eyinhloko kufanele ishintshwe. Iziphetho ezimbili zephampu yegiya zivalwa ngamapuleti aseceleni ensimbi amabili afakwe ingxubevange yethusi. Uma i-alloy yethusi emaceleni ahlangene iwa noma igqoke kakhulu, ipompo ye-hydraulic ngeke ikwazi ukuletha amafutha okucindezela okwanele. Ipompo ye-hydraulic kufanele futhi ishintshwe ngalesi sikhathi. Isifo igovu-gazinga
7) Uma i-boom lift ibuthakathaka kodwa ibhakede lihlehla ngokujwayelekile, kusho ukuthi ipompo ye-hydraulic, isihlungi, i-valve yokusabalalisa ukugeleza, i-valve yokuphepha eyinhloko kanye nezinga lokushisa likawoyela kuvamile. Vele uqinisekise futhi uxazulule ezinye izici.
Iphutha lesi-3: Ukuhoxiswa kwebhakede akunamandla
Ukuhlaziywa kwesizathu:
I-1) Ipompo eyinhloko ihluleka futhi isihlungi sivalekile, okuholela ekuletheni amafutha anganele kanye nokucindezela okunganele kupompo ye-hydraulic.
I-2) I-valve yokuphepha eyinhloko ihluleka. I-valve core ibambekile noma isivalo asiqinile noma ukulawulwa kwengcindezi kuphansi kakhulu.
I-3) I-valve yokulawula ukugeleza ihluleka. Igebe likhulu kakhulu futhi i-valve yendlela eyodwa kuvalvu ayivalwanga ngokuqinile.
4) Imbobo yevalvu ehlehlisa ibhakede kanye nembobo yomzimba ye-valve inkulu kakhulu, ibambeke endaweni yokukhipha uwoyela, futhi isiphethu sokubuya siyahluleka.
5) I-valve yokuphepha esebenza kabili iyehluleka. I-valve core ibambekile noma uphawu aluqinile.
I-6) Indandatho yokuvala yebhakede ye-hydraulic cylinder yonakalisiwe, igugile kakhulu, futhi umgqomo we-cylinder uyacindezelwa.
Ukuxazulula inkinga:
1) Hlola ukuthi i-boom lift inamandla yini. Uma i-boom lift ijwayelekile, kusho ukuthi ipompo ye-hydraulic, isihlungi, i-valve yokulawula ukugeleza, i-valve yokuphepha eyinhloko kanye nezinga lokushisa likawoyela kuyinto evamile. Uma kungenjalo, xazulula inkinga ngendlela echazwe ku-Symptom 2.
2) Hlola igebe phakathi komnyombo wevalvu ehlehlisa ibhakede kanye nembobo yomzimba wevalvu. Igebe lomkhawulo lingaphakathi kuka-0.04mm. Hlanza i-valve yama-slide futhi ulungise noma ushintshe izingxenye.
3) Hlukanisa futhi uhlole ukuvala nokuguquguquka phakathi kwe-valve core kanye nesihlalo se-valve ye-valve yokuphepha esebenza kabili kanye nomgogodla we-valve kanye nesihlalo se-valve ye-valve yendlela eyodwa, futhi uhlanze umzimba we-valve kanye ne-valve core.
4) Hlukanisa futhi uhlole isilinda se-hydraulic yebhakede. Ingenziwa ngokuya ngendlela yokuhlola yesilinda se-boom hydraulic echazwe ku-fault phenomenon 2.
Sizophinde sikhiphe ingxenye yesibili yokuqukethwe kamuva, ngakho hlala ubukele.
Uma udinga ukuthengaizesekeli zokulayisha or izilayishi ezisetshenziswa ngesandla, ungasithinta. I-CCMIE izokusebenzela ngenhliziyo yonke!
