Kungani i-single hydraulic control foot pedal isetshenziswa kabanzi emishinini yokwakha?

Ezinhlelweni zokulawula i-hydraulic zemishini yokwakha efana nama-loader, ama-crane, kanye nama-excavator, i-pedal eyodwa yokulawula i-hydraulic foot ivame kakhulu. Yimaphi “amakhono” ethembele kuwo ukuze ibe “isivakashi esihlala njalo” ohlelweni lwe-hydraulic lwemishini enjalo? Ngemuva kwalokhu umphumela wezimpawu zayo ezivumelaniswe ngokujulile nezigcawu zokusebenza kwemishini yokwakha.

Ingqikithi ye-single hydraulic control foot pedal yi-mechanical foot valve, futhi i-core working logic ayinzima: ngokunyathela noma ngokukhulula i-foot pedal, ukuvulwa nokuvalwa kwe-valve yangaphakathi kulawulwa, ngaleyo ndlela kuqashelwe ukunqanyulwa kokugeleza kwesistimu ye-hydraulic kanye noshintsho lwendlela yokugeleza. Indlela yokusebenza ebonakala ilula ingadlala inani eliyingqayizivele endaweni yokusebenza yemishini yokwakha.

1. Ukuxhumanisa ukusebenza: khulula izandla zakho bese ugxila emisebenzini eyinhloko

Imisebenzi yemishini yokwakha ivame ukudinga ukuhlanganiswa kwezenzo eziningi. Uma sithatha i-excavator njengesibonelo, umqhubi kumele alawule ukumba nokukhipha ibhakede, futhi alungise ukuma kwe-boom kanye nengalo ye-dipper. Zombili izandla zithwala umthwalo onzima wokusebenza kahle. Ukuvela kwe-single hydraulic control foot pedal kwenza "unyawo" lube yingxenye entsha yokulawula uhlelo lwe-hydraulic - ngokunyathela i-pedal, ukugeleza noma isiqondiso sesekethe ye-hydraulic kungalungiswa ngaphandle kokumisa isenzo sesandla. Isibonelo, lapho i-excavator ilinganisa indawo, i-foot pedal elawulwa unyawo ilungisa ingcindezi ye-hydraulic ye-boom, futhi zombili izandla zigxile ekulinganiseni okuncane kwebhakede. Inqubo yokusebenza iqondakala kakhudlwana futhi ukusebenza kahle kokusebenza kuyathuthukiswa ngokwemvelo.

Ngesikhathi sokuthulula umthwalo wokulayisha, umshayeli udinga ukulawula i-engeli yokuthambekela kwebhakede kanye nokushayela imoto ngesikhathi esifanayo. I-pedal eyodwa ye-hydraulic foot ivumela unyawo ukuthi luthathe umsebenzi wokulawula ingcindezi ye-hydraulic yebhakede, futhi zombili izandla zingasebenzisa isiteringi ngokuguquguquka futhi zilawule ijubane lemoto, zenze indawo yokukhulula umthwalo ibe nenembile kakhudlwana, zigweme ukuchitheka kwezinto, futhi zithuthukise ukumiswa kokwakhiwa. Le ndlela "yokwahlukaniswa komsebenzi ngezandla" ihlangabezana nezidingo zokusebenza kokuxhumanisa izenzo eziningi zemishini yobunjiniyela, yenza ngcono kakhulu ulwazi lokusebenza, futhi inciphise ukukhathala komqhubi.

2. Ukuzivumelanisa nokusebenza: ukuguquguquka nokunembile, ukubhekana nezimo zokusebenza eziyinkimbinkimbi

(I) Ukusebenza kwe-Bidirectional kanye nokulungiswa okuncane

Izimo zokusebenza ezibhekene nemishini yobunjiniyela ziyinkimbinkimbi futhi ziyahlukahluka, futhi ukuguquguquka nokunemba kokulawulwa kwe-hydraulic kuphakeme kakhulu. Ama-valve amaningi ezinyawo ze-hydraulic asekela ukusebenza kwezindlela ezimbili. Ngaphezu kwemisebenzi eyisisekelo yokuvula i-valve ngokuyinyathela nokuyivala ngokuyikhulula, eminye imiklamo ingalungisa nokushaya kwe-pedal kanye namandla e-pedal.

Uma sithatha imisebenzi yokuphakamisa i-crane njengesibonelo, ukuphakamisa izimpahla ezinesisindo esihlukene kudinga amazinga ahlukene okugeleza kwe-hydraulic. Ngokulungisa i-pedal stroke, ukuvulwa kwe-valve kungalawulwa ukuze kufezwe izinguquko ezincane ezingeni lokugeleza kukawoyela we-hydraulic, okwenza ukuphakama kwe-boom nokuwa kuqine kakhulu futhi kugweme izinto ezisindayo ukuthi zinganyakaziswa. Ngesikhathi sokusebenza kokuchoboza i-excavator, amandla e-pedal alungiswa ngokuya ngobunzima bedwala ukulawula imvamisa namandla e-hammer ukuze kuvumelane namandla ahlukene okwakha nokuthuthukisa umphumela wokusebenza. Leli khono lokulungisa eliguquguqukayo livumela i-pedal eyodwa yokulawula i-hydraulic ukuthi "ivumelane nezimo zendawo" futhi ivumelane nezimo zokusebenza ezahlukahlukene.

(II) Umphelezeli othembekile nohlala isikhathi eside, ozinzile

Indawo yokusebenza kwemishini yokwakha inzima, futhi uhlelo lwe-hydraulic lucindezelwa kakhulu futhi ludlidliza isikhathi eside, okubeka izidingo eziqinile ekuthembekeni kwezingxenye. I-pedal eyodwa yokulawula i-hydraulic yenziwe ngezinto ezingagugi futhi ezingacindezeli kakhulu. Umzimba we-valve kanye nesakhiwo sokuvala kulungiselelwe kahle futhi kungasebenza kahle endaweni ye-hydraulic enomfutho ophezulu, okugwema ngempumelelo izinkinga zokuvuza.

Ama-loader asebenza ezimayini abhekene nothuli, amaqhubu, kanye nokushaqeka kwe-hydraulic okunomfutho ophezulu. Izinto ezingagugi ze-pedal zingamelana nokuguguleka kokunyathelwa isikhathi eside, kanti ukumelana nomfutho ophezulu kuqinisekisa ukuthi i-valve isakwazi ukuvala kahle lapho umfutho wesistimu ushintshashintsha. Ngisho nokusetshenziswa kwemvamisa ephezulu isikhathi eside, ukusebenza kwayo kuyawohloka kancane, kunciphisa isikhathi sokungasebenzi kwemishini okubangelwa ukwehluleka kwezingxenye, kuqinisekisa ukuqhubeka kokwakhiwa, futhi "kumboze" inqubekela phambili yephrojekthi.

3. Isimo sokufunwa okuqinile: ukugcwalisa igebe lokusebenza lokulawula kwe-hydraulic

Uhlelo lwe-hydraulic lwemishini yokwakha ludinga indlela yokulawula ukusebenza elula, ephumelelayo neyinkimbinkimbi. Ama-valve esandla adinga izinsiza zokusebenza ngesandla futhi "amatasa kakhulu" kalula ezimweni zokuxhumanisa izenzo eziningi; yize i-valve yokulawula kagesi inembile, inqunyelwe yizindleko, izintambo kanye nokuzivumelanisa nezimo zemvelo (njengezindawo ezinomswakama nezinothuli ezivame ukwehluleka).

I-pedal eyodwa yokulawula i-hydraulic igwema ukushiyeka okuthile kwama-valve asetshenziswa ngesandla nama-valve okulawula kagesi ngendlela "yesakhiwo semishini + ukusebenza kwezinyawo": akudingeki izintambo eziyinkimbinkimbi, akukho ukwesaba ukuphazamiseka okuvela ezindaweni ezinzima, futhi kusetshenziswa izimiso zemishini ezilula nezithembekile ukufeza ukusebenza "kokuphambuka" kokulawula i-hydraulic. Igcwalisa isidingo "sezingxenyana zokusebenza ngaphandle kwezandla" ekulawuleni i-hydraulic kwemishini yokwakha, okwenza inqubo yokusebenza ibe nengqondo futhi isebenze kahle, futhi ngokwemvelo iba ukukhetha "okujwayelekile" kwezinhlelo ze-hydraulic zama-loaders, ama-crane, ama-excavator kanye neminye imishini.

Kusukela ekuthuthukiseni ukusebenza kahle kokuxhumanisa ukusebenza, kuya ekuqondeni nasekuqineni kokuzivumelanisa nokusebenza, kuya ekugcwaliseni igebe lesidingo esiqinile sendawo, i-pedal eyodwa yokulawula i-hydraulic control foot ihlangabezana ngokujulile nezidingo zokusebenza zemishini yokwakha ngezici zayo. Nakuba incane, idlala indima ebalulekile "ekuxhumaneni kokulawula" kohlelo lwe-hydraulic, isiza imishini yokwakha ukuthi isebenze kahle futhi ngokuzinzile ngaphansi kwezimo zokusebenza eziyinkimbinkimbi, iba "iqhawe elingemuva kwesehlakalo" ukukhuthaza intuthuko ebushelelezi yokwakha ubunjiniyela, kanye nokuhumusha umqondo oyisisekelo wezingxenye zezimboni ezisetshenziswa kabanzi ngenxa "yokuzivumelanisa ngqo nezigcawu".
