Ulwimi
Umthengisi wezixhobo zokwakha izisombululo zoomatshini bokwakha kangangeminyaka engama-30.
Ukuthenga ii-mini excavators zaseTshayina kunokuba linyathelo elilumkileyo, kodwa kuphela ukuba uhlola umatshini njengonjineli, kungekhona njengomntu oskrola ixabiso eliphantsi ezinzulwini zobusuku. Imakethi inkulu ngokwaneleyo ukuba ifanele ingqwalaselo enzulu. Ngokutsho kwe- Ingxelo yemarike ye-mini excavator ye-Market Research Future , imakethi yehlabathi ye-mini excavator yayixabisa i -USD 8.26 yeebhiliyoni ngo-2024 kwaye kulindeleke ukuba ifikelele kwi -USD 15.82 yeebhiliyoni ngo-2035 . NgesiNgesi esilula, abantu abaninzi bathenga ezi matshini, kwaye ayingabo bonke abathenga ngobulumko.
I-China ikwayinxalenye ephambili yaloo mfanekiso wobonelelo. Idatha yorhwebo lwe-WITS yeBhanki yeHlabathi ye-HS 842952 ibonisa ukuba i-United States ingenise iiyunithi ezili-110,573 kolu didi lokumba ngo-2024, kuquka iiyunithi ezingama-29,353 ezivela eTshayina . Oko akuthethi ukuba yonke i-mini excavator yaseTshayina ilungile, kwaye ngokuqinisekileyo akuthethi ukuba yonke imashini engabizi kakhulu imbi. Oku kuthetha ukuba abathengi bafuna uluhlu lokuhlola olusemgangathweni olufanelekileyo ngaphambi kokuba bahlawule idiphozithi.
Impazamo yokuqala kukuthelekisa oomatshini ngexabiso kuphela. I-mini excavator ayisiyomveliso inye esisigxina. I-Caterpillar ichaza ii-mini-graveers njengeematshini eziqala ngaphantsi kwe-metric ton enye ukuya kwi-metric ton ezili-10 , ezinomthamo wokuphakamisa ukusuka kwi- 1,000 lb kwiimodeli ezincinci ukuya ngaphezulu kwe- 5,000 lb kwiimodeli ezinkulu ze-8-10 ton. Loo nto ibanzi kakhulu. Umatshini wegadi kunye nomatshini wokutsala imisele zombini zinokubizwa ngokuba "zii-mini excavators," kodwa aziphili ubomi obufanayo.
Ngaphambi kokuba ubuze ixabiso elifanelekileyo, chaza umsebenzi. Ubungakanani ubunzulu omele umbe? Ngaba umatshini uza kuthwala i-breaker, i-auger, i-rake okanye i-flail mower? Ngaba uza kusebenza kumhlaba othambileyo, iingcango eziqinileyo, amathambeka okanye imisebenzi yokuqeshisa apho abaqhubi banokuwuphatha ngobunono njengenqwelo yokuthenga? Nje ukuba umsebenzi ucace, ubungakanani bomatshini buqala ukuba nentsingiselo.
Incwadana yomthengisi kufuneka ikunike amanani anokulinganiswa, ingabi zizichazi ezinobuhlobo kuphela. Ukuze ube nomlinganiselo oluncedo, Iphepha leenkcukacha zeCat 301.8 idwelisa amandla acocekileyo angama-21 hp , ubunzima bokusebenza obuyi-2,029 kg , ubunzulu bokumba obuyi-2,570 mm , ukuhamba kwepompo eyi-66 L/min kunye noxinzelelo lwezixhobo zebha ezingama-245 . I-mini excavator yaseTshayina kwiklasi efanayo ye-1.8-2 ton ayidingi ukukopa loo manani ngokuchanekileyo, kodwa umthengisi kufuneka akwazi ukubonelela ngohlobo olufanayo lwedatha.

Ukuba umthengisi uyaziphepha ezi nombolo, yehlisa isantya. Umenzi wokwenyani okanye umthengisi othembekileyo akufuneki afune iintsuku ezintathu ukuze afumane ubunzima bokusebenza komatshini wakhe.
Injini ifumana ingqalelo kuba abathengi bayawaqonda amagama eemveliso. Oko kulungile, kodwa inkqubo ye-hydraulic igqiba indlela umatshini oziva ngayo ngokwenene. I-mini excavator ene-hydraulic matching embi ingabonakala intle kwiifoto kwaye isaziva ivila kwindawo yayo. I-boom ingaphakama kancinci, ingalo inganqikaza, okanye i-attachment ingasebenza ngathi itye isidlo sasemini eside.
Xa uphonononga i-mini excavator yaseTshayina, thelekisa amandla enjini, ukuhamba kwepompo, uxinzelelo kunye namandla okupholisa kunye. Ukuba uceba ukusebenzisa i-breaker okanye i-auger, cela ukuhamba kunye noxinzelelo oluncedisayo, uze uthelekise loo manani kunye nemfuneko yokuncamathisela. I-benchmark ye-Cat 301.8 ye- 66 L/min pump flow kunye noxinzelelo lwe-245 bar inika abathengi indawo efanelekileyo yokujonga olu didi lomatshini. Ngaphandle kwedatha yokuhamba kunye noxinzelelo, awuthelekisi oomatshini ngokwenene; uthelekisa imibala yepeyinti.
Isithuthi esingaphantsi kwemoto kulapho oomatshini abaninzi “abangabizi” babiza khona ngokuthe cwaka. I-Caterpillar iphawula kwi-"undercarriage" yayo. isikhokelo somgxobhozo ongaphantsi kwesithuthi sokumba ukuba iingxaki ezinxulumene nesithuthi esingaphantsi kwesithuthi zinokumela ngaphezulu kwesiqingatha seendleko zokugcinwa kwemigodi . Elo nani lodwa lisizathu esaneleyo sokujonga ngokusondeleyo iindlela, iirola, ii-sprocket kunye nee-final drives ngaphambi kokuthunyelwa.
Cela iifoto ezikufutshane kunye nevidiyo ebalekayo. Imizila mayihlale ithe tye, iirola akufuneki zibonise ukuvuza okucacileyo, kwaye iidrive zokugqibela mazihlale zomile emva kokuba umatshini ufudumale. Ukuba umatshini unesithuthi esingaphantsi esinokwandiswa, vavanya zombini ezi ndawo. Kufuneka utyibilike kakuhle ngaphandle kokubopha. Ukuba uhamba njengedrowa enomhlwa, cinga ukuba uza kuziphatha njani emva kweenyanga ezintandathu eludakeni.
Ukuwelda kakuhle akupheleli nje ekubeni yintsimbi ecocekileyo. Kumalunga nokungaguquguquki kwiindawo ezithwala uxinzelelo: i-boom foot, i-arm joint, i-blade mount, i-swing bracket kunye ne-track frame. Khangela ukuba akukho ntsimbi inqunyulweyo, i-porosity, ubungakanani be-weld obungalinganiyo kunye nokusila okukrokrisayo. Ipeyinti entsha inokwenza umsebenzi onzima ubonakale unomtsalane okwethutyana, kodwa ukungcangcazela kunomkhwa ombi wokutyhila iimfihlo.
Ulwakhiwo lokhuseleko nalo lufuna ubungqina, hayi amagama abhaliweyo. I-Cat 301.8 idwelisa imigangatho efana ne -ROPS ISO 12117-2:2008 , i-TOPS ISO 12117:1997 kunye ne -Top Guard ISO 10262:1998 Level I kwiinkcukacha zemveliso yayo. Ukuba umthengisi uthi ikhabhini "ikhuselekile," buza ukuba yeyiphi imigangatho ehlangabezana nayo. Kwiimarike zokuthumela ngaphandle, imigangatho eqanjiweyo ibaluleke ngaphezu kwamagama aqinisekileyo.
Ukuthobela imithetho akuyonto incinci kulawulo. Kwiimashini zedizili eziya eMelika, Imithetho ye-US EPA ye-diesel injini yezixhobo ezinzima Igubungela izixhobo ezingezizo iindlela ezifana nee-emba, kwaye i-EPA ithi idizili yesalfure ephantsi kakhulu inomlinganiselo ophezulu wesalfure we- 15 ppm . Abathengi kufuneka bajonge ilebhile yenjini, isatifikethi se-EPA kunye ne-invoyisi ngaphambi kokuba ithunyelwe, kungekhona emva kokuba umatshini ufike kwi-customs.
Kubathengi be-EU, ibhendi yamandla enjini kunye nokuthobela iSigaba V kubalulekile. Umgaqo we-EU 2016/1628 imisela imida yokukhupha umbane kwiinjini zoomatshini abaphathwayo ezingezizo iindlela, kuquka neendlela eziqhelekileyo zamandla okumba iimoto ezincinci. Ukuba umthengisi akanakukwazi ukuchaza ukuba injini iyahambelana ne-EPA, i-CE okanye iSigaba V, loo nto ayisiyo "ngxaki ingako yamaphepha." Ingachaphazela ukucocwa kwempahla, ixabiso lokuthengisa kwakhona kunye nokuthenjwa kwabathengi.
Ukuhlolwa kwangaphambili kokuthunyelwa kufanele kubonise ukuba umatshini usebenza, kungekhona nje ukuma. Cela ividiyo equka ukuqala ngokubandayo, ukungenzi nto, ukujija ngokupheleleyo, ukuphakanyiswa kwe-boom, intshukumo yengalo, ukugoba kwebhakethi, ukujija, ukusebenza kweeblade, ukuhamba macala omabini kunye nokusebenza kwe-hydraulic. Ukuhambahamba imizuzu emibini ngomculo omnandi ongasemva akulovavanyo. Lukhuphiswano lobuhle bomatshini.
