uthetha nge Excavator(1)
Ihlelwa njengoomatshini bokwakha obunzima, i-excavator, eyaziwa ngokuba ngoomatshini bokumba, okwaziwa ngokuba yi-excavator, ngumatshini ohambisa umhlaba osebenzisa ibhakethi ukumba izinto ngaphezulu okanye ngaphantsi kwendawo yokuthwala kwaye uyilayishe kwisithuthi sothutho okanye ukuyothula. ukuya estokhweni.
Izinto ezigrunjwe ngummbi ngokuyintloko ngumhlaba, amalahle, intlenga, umhlaba kunye nelitye emva kokukhulula kwangaphambili. Ukuqwalasela uphuhliso loomatshini bokwakha kwiminyaka yakutshanje, uphuhliso lwe-excavators lukhawuleza ngokukhawuleza, kwaye abembi baye baba yenye yezona zinto zibalulekileyo. oomatshini bokwakha kulwakhiwo lobunjineli.Iiparameters ezintathu ezibalulekileyo ze-excavator: ubunzima bokusebenza (ubunzima), amandla e-injini kunye nomthamo webhakethi.
Ukwahlulwe kwi-excavators yangaphakathi yokutshisa kunye ne-electric drive excavators ngokwendlela yokuqhuba, ngokwendlela yokuhamba, inokwahlulwa ibe ngabaqhubi be-crawler kunye nabembi abanamavili.
Ngokwemowudi yothumelo, inokwahlulwa ibe yi-excavators ye-hydraulic kunye ne-excavators yomatshini, ukuba ngokwebhakethi, ineendlela ezimbini: ukumba ifosholo yangaphambili, ukugrumba kwe-backhoe.
Ubunzima bokusebenza ngenye yeeparitha ezintathu ezibalulekileyo ze-excavator (amandla e-injini, umthamo we-emele, ubunzima bokusebenza), Ubunzima bokusebenza bumisela inqanaba le-excavator kwaye limisela umda ophezulu wamandla okumba we-excavator.
Amandla okwemba≦m;
Ubunzima bokusebenza m: i-coefficient yokubambelela phakathi komhlaba kunye ne-crawler, Ukuba amandla okumba adlula lo mda, kwimeko ye-backhoe, i-excavator iya kutyibilika kwaye itsalwe phambili, eyingozi kakhulu.Kwimeko yefosholo, i-excavator iya kutyibilika ngasemva.I-Digging force, yamandla okumba, amandla okumba, amandla okumba ahlulwe ngokukodwa kwi-forearm yokumba amandla kunye namandla okumba ibhakethi.
Amanqaku esenzo semikhosi emibini yokumba iingcambu zezinyo kwibhakethi (umlomo webhakethi), kodwa amandla ahluke.I-forearm yokumba amandla avela kwi-cylinder forearm;amandla okumba ibhakethi avela kwi-cylinder yeoli yebhakethi.
Uxinzelelo oluthile lomhlaba, ubungakanani boxinzelelo oluthile lomhlaba lumisela iimeko zomhlaba ezifanelekileyo ukuba umgodi usebenze. = ubunzima bokusebenza ÷ yonke indawo edibana nomhlaba,Landela izihlangu, kubalulekile ukufakela izihlangu zomkhondo ezifanelekileyo kumatshini.Kubantu abakhasayo, indlela yokukhetha isirhubuluzi kukuba: Nanini na kunokwenzeka, zama ukusebenzisa ezona zihlangu zimxinwa.
Iindidi zengoma eziqhelekileyo: izihlangu zengoma enamazinyo, izihlangu ezisicaba, izihlangu ezisicaba,Isantya sokuhamba, abakhasayo abakhasayo, ixesha lokuhamba libalelwa malunga nesinye eshumini salo lonke ixesha lokusebenza.
Ngokuqhelekileyo, isantya ezibini sinokuhlangabezana nokusebenza kokuhamba kwe-excavator.I-Traction force, i-traction force ibhekisela kumandla okwenziwa ngumqhubi xa ehamba, exhomekeke kakhulu kwimoto yokuhamba ye-excavator. ye-excavator kunye nokukwazi kwayo ukuhamba.Ingabonakaliswa kwiisampuli zabakhiqizi abahlukeneyo.
Umgangatho, ubungakanani bomgangatho bubhekiselele kubuchule bokunyuka, ukwehla, okanye ukuma kwindawo ethambekileyo, kwinqanaba lokuthambeka. Iindlela ezimbini zokubonisa: i-engile, ipesenti, umthamo wokuphakamisa, umthamo wokunyusa ubhekiselele kumthamo omncinci olinganisiweyo wokuphakamisa ozinzileyo okanye umthamo olinganisiweyo wokuphakamisa ihydraulic. .Ukulinganiswa komthamo ozinzileyo wokuphakamisa: i-75% yomthwalo wokukhupha, ukulinganisa umthamo wokuphakamisa i-hydraulic: i-87% ye-hydraulic lift capacity
Isantya sojingi sibhekisa kumlinganiselo wesantya esiphezulu esinokufikelelwa ngumembi ngexesha lokujingi okuzinzile xa i-excavator isothulwa.Oku kuthetha ukuba isantya esichaziweyo sokuxhwitha, ingekuko xa uqalisa, okanye xa uqhoqhoqho; .Kumsebenzi wokugrumba jikelele, Xa lo mgrumbi usebenza kuluhlu lwe-0 ° ukuya kwi-180 °, i-motor yokuxhela ikhawuleza okanye iyancipha, kwaye xa ijika ukuya kuluhlu lwama-270 ° ukuya kwi-360 °, isantya sokuxhela siyazinza. umsebenzi wokugrumba, isantya sokujikeleza esichazwe ngasentla asiyonyani.
Oko kukuthi, ujingi olufunekayo lokwenene lusebenza kukukhawulezisa/ukwehliswa kwesantya esichazwe ngokwemigaqo yetorque. Amandla asebenzayo (amandla omnatha ehashe) abhekiselele kumandla aphumayo alinganiswe kwi-flywheel ye-injini enazo zonke izincedisi ezisebenzisa amandla ezifana ne-mufflers, iifeni, iialternator kunye nezihluzo zomoya ezifakelweyo.
Umlinganiselo wengxolo, ingxolo ye-excavator ivela ikakhulu kwi-injini.Iindidi ezimbini zengxolo: umlinganiselo wengxolo kwindlebe yomsebenzisi, umlinganiselo wengxolo ojikeleze umatshini
