Mechanical excavatoriimfuno zomgangatho wokuhlola

01Ukuhlolwa kweMechanical excavator-ukuhlolwa kwendawo yokusebenza yomqhubi

-Izixhobo

Ikhebhu yomqhubi kufuneka ifakwe kwindawo yomqhubi kumatshini wokukhwela.

Oomatshini abanobunzima bokusebenza obungaphezulu kwe-1,500 kg kunye nendawo yomqhubi kufuneka baxhotyiswe ngekhebhu yomqhubi. Oomatshini abanobunzima bokusebenza obungaphantsi okanye obulingana ne-1,500 kg abadingeki ukuba baxhotyiswe ngekhebhu yomqhubi.

Oomatshini bokushukuma komhlaba kufuneka bayilwe ukuze kuqinisekiswe ukuba kufakelwe izixhobo ezifanelekileyo zokukhusela xa zisetyenziswa kwizicelo apho kukho umngcipheko wobutyobo obubhabhayo (umz. ukusebenzisa iihydraulics).

-Indawo encinci yomsebenzi

Esona sithuba sincinci sokushukuma kubaqhubi kufuneka sihambelane ne-ISO 3411.

Ubuncinci besithuba somqhubi kunye nendawo yolawulo kufuneka ihambelane ne-ISO 6682

-Amalungu ashukumayo

Amalungiselelo kufuneka enziwe ukuphepha ukudibana ngengozi kwindawo yomqhubi kunye neendawo ezihambayo ezifana namavili, amabhanti okanye izixhobo zokusebenza okanye izinto eziqhotyoshelweyo.

-Ukuphelelwa kwenjini

Irhasi yokukhupha ephuma kwi-injini kufuneka igcinwe kude nomqhubi kunye ne-air inlet ye-cab

- Ukuthenga kunye nediphozithi yelayisensi yokuqhuba

Indawo kufuneka inikwe kufutshane nendawo yomqhubi ukugcina ngokukhuselekileyo incwadi yomqhubi okanye eminye imiyalelo yokusebenza. Ukuba indawo yomqhubi ayikwazi ukutshixwa okanye akukho cab yomqhubi, isithuba kufuneka sitshixeke.

-Iincam ezibukhali

Akufunekanga kubekho iikona ezibukhali okanye iikona kwindawo yokusebenzela yomqhubi (efana nesilingi, ipaneli yesixhobo sangaphakathi kunye nendlela eya kwindawo yomqhubi).

-Iimeko zemozulu kwindawo yomqhubi

Ikhebhu yomqhubi kufuneka ikhusele umqhubi kwiimeko zemozulu ezimbi ezinokubonwa kwangaphambili. Amalungiselelo eenkqubo zokungenisa umoya, iinkqubo zokufudumeza ezilungelelanisiweyo kunye neenkqubo zokucima iglasi kufuneka zifakwe ngokuhambelana nemimiselo.

-Imibhobho eqinile kunye nemibhobho

Ikhebhu ixhotyiswe ngoxinzelelo lolwelo olukhulu kune-5 MPa okanye ubushushu obungaphezulu kwama-60 C kunye nemibhobho.

-Basic yokungena kunye nokuphuma

Kuya kubonelelwa ngofikelelo olusisiseko, imilinganiselo eya kuthi ihambelane ne-ISO 2867.

-Ukungena nokuphuma ngenye indlela

Enye indlela yokungena/yokuphuma iya kubonelelwa kwicala elahlukileyo ukusuka kwindawo yokuqala yokungena/yokuphuma. Imilinganiselo yayo iya kuhambelana ne-ISO 2867. Oku kunokuba yifestile okanye olunye ucango olunokuvulwa okanye luhanjiswe ngaphandle kwezitshixo okanye izixhobo. Ukuba umnyango unokuvulwa ngaphakathi ngaphandle kwesitshixo okanye izixhobo, sebenzisa i-latch. Iingcango zeglasi ezaphukayo kunye neefestile zobukhulu obufanelekileyo zinokuqwalaselwa njengenye indlela yokuphuma efanelekileyo, ngaphandle kokuba ihamile yokuphuma eyimfuneko ibonelelwe kwikhebhu kwaye ibekwe kwindawo apho umqhubi angafikelela khona.

-Inkqubo yokungenisa umoya

Inkqubo yokungenisa umoya kufuneka ikwazi ukunika umoya omtsha kwikhebhu yomqhubi kunye nesantya sokuhamba esingekho ngaphantsi kwe-43 m / h. Izihluzi ziya kuvavanywa ngokuhambelana ne-SO 10263-2.

-Inkqubo ye-Defrost

Inkqubo yokuphelisa iqhwa kufuneka ibonelele ngezixhobo zokunyibilikisa iifestile zangaphambili nasemva, ezifana nenkqubo yokufudumeza okanye isixhobo esizinikeleyo sokuphelisa iqhwa.

-Inkqubo yokutshaja kakhulu

Ukuba i-cab ene-pressurization system inikezelwa, inkqubo yoxinzelelo iya kuvavanywa ngokuhambelana nemimiselo ye-SO 10263-3 kwaye iya kubonelela ngoxinzelelo lwangaphakathi lwangaphakathi olungekho ngaphantsi kwe-50 Pa.

-Iminyango kunye neefestile

Iingcango, iifestile kunye neeflephu kufuneka zithintelwe ngokukhuselekileyo kwiindawo ezijoliswe kuzo. Iingcango kufuneka zigcinwe kwindawo yazo yokusebenza ekujoliswe kuyo ngezithintelo eziqinileyo ezenzelwe ukugcina ukuvulwa okukhuselekileyo kokungena kwesiseko kunye nokuphuma kwindawo yokusebenza ekujoliswe kuyo, kwaye izithintelo kufuneka zikhutshwe ngokulula kwindawo yomqhubi okanye iqonga lokungena lomqhubi.

Iifestile zeemoto kufuneka zifakwe ngokukhuselekileyo okanye ezinye izinto ezinokusebenza okufanayo kokhuseleko.

Iifestile zangaphambili kufuneka zixhotyiswe ngee wipers zombane kunye ne washers.

Itanki yamanzi yokuhlamba ifestile kufuneka ifikeleleke ngokulula.

-Ukukhanya kwangaphakathi

I-cab yomqhubi kufuneka ixhotyiswe ngesixhobo sokukhanyisa sangaphakathi esisisigxina, ekufuneka sisebenze emva kokuba injini icinyiwe, ukuze indawo yomqhubi ikhanyise kwaye ifunde incwadi yomqhubi.

-Ikhaka elikhuselayo lomqhubi

Abenzi be-Mechanical excavators kufuneka bakwazi ukufaka izakhiwo zokukhusela umqhubi (abagadi abaphezulu kunye nabagadi bangaphambili). Umenzi kufuneka anike izakhiwo zokukhusela (abagadi abaphezulu kunye nabagadi bangaphambili), ekufuneka zikhethwe ngumsebenzisi ngokusekelwe kwimingcipheko ekhoyo yesicelo.

-ISakhiwo soKhuseleko seNto esiwayo (FOPS)

Ngaphandle kwezinxaxhi ezichazwe kwi-ISO3449, iikhreyini ezisikwere ekulindeleke ukuba zisetyenziswe kwiindawo ezineengozi zezinto eziwayo kufuneka ziyilwe ukuze zikwazi ukufakela isakhiwo esikhuselayo sento ewayo (FOPS).

02UHlolo lweMechanical Excavator -Ulawulo lomqhubi kunye nezalathisi

-Qalisa kwaye umise isixhobo

Oomatshini bokushukuma komhlaba kufuneka baxhotyiswe ngezixhobo zokuqalisa nokumisa (ezifana nezitshixo), kwaye inkqubo yokuqalisa kufuneka ixhotyiswe ngezixhobo zokukhusela ukuthintela ukusetyenziswa okungagunyaziswanga.

Oomatshini abashukumayo bomhlaba baya kuyilwa kangangokuba xa injini iqaliswa okanye imisiwe, akunakwenzeka ukuba ushukumise umatshini, izixhobo zokusebenza kunye noncamathiselo ngaphandle kokuqalisa ulawulo.

-Ukusebenza okungalindelekanga

Izixhobo zokulawula ezinokubangela ingozi ngenxa yokusebenza ngengozi kufuneka zilungiswe okanye zivalwe okanye zikhuselwe ngokuhambelana nomgaqo wokunciphisa umngcipheko. Ngokukodwa, xa umqhubi engena kwaye ephuma kwindawo yomqhubi, isixhobo esikhubaza ulawulo kufuneka sizenzele ngokwaso, okanye Sinyanzeliswa ngenkani kwaye sisebenze ngezixhobo ezifanelekileyo.

-i-pedal pedal

Kufuneka kubekho ubungakanani obufanelekileyo, imilo kunye nesithuba esaneleyo phakathi kwabo. Ukunyathela kufuneka kube nendawo engatyibilikiyo kwaye kube lula ukuyicoca. Ukuba iipedals zoomatshini abahamba emhlabeni kunye neepedals zeemoto zinemisebenzi efanayo (i-clutch, i-braking kunye ne-acceleration), ukwenzela ukuphepha ingozi ebangelwa ukuxuba, ii-pedals kufuneka zilungiswe ngendlela efanayo.

-Ukufika ngokungxamisekileyo kweziqhoboshelo

Ukuba injini iyayeka, kuya kwenzeka ukuba:

· Nciphisa isixhobo esisebenzayo/uncamathiselo phantsi/indawo yokubeka;

· Ukwehliswa kweyunithi yomsebenzi/uncamathiselo kubonakala ukusuka kwindawo apho umqhubi avule ulawulo lokwehlisa:

· Ukuphelisa uxinzelelo olushiyekileyo kwisekethe nganye ye-hydraulic kunye ne-pneumatic yezixhobo zokusebenza / izixhobo ezincedisayo ezinokuthi zibangele umngcipheko. Izibonelelo zokunciphisa iziqhotyoshelo kunye neendlela zokususa uxinzelelo olushiyekileyo lunokuthi lube ngaphandle kwendawo yomqhubi kwaye iya kuchazwa kwincwadi yomqhubi.

-Intshukumo engalawulekiyo

Ukushukuma koomatshini kunye nezixhobo zokusebenza okanye uncamathiselo olusuka kwindawo elimisiweyo, ngaphandle kwaxa luqhutywa ngumqhubi, ngenxa yokutyibilika okanye ukucotha (umz. okubangelwa kukuvuza) okanye xa unikezelo lombane luphazamisekile, luya kulawulwa ngaphakathi kuluhlu olungadali mngcipheko. kubantu abatyhilekileyo.

-Imiboniso ebonakalayo / iiphaneli zokulawula, izikhombisi kunye neempawu
