Mupi wezvishandiso zvekuvaka kwemakore makumi matatu.
Kutenga ma mini excavator ekuChina kunogona kuva danho rakanaka, asi chete kana ukaongorora muchina semainjiniya, kwete semunhu ari kuskerera mutengo wakaderera pakati pehusiku. Musika wakakura zvakakwana zvekuti unofanirwa kutariswa zvakanyanya. Sekureva kwazvinoitwa nekambani yeChinese Mini Excavator, musika wacho wakakura zvekuti unofanirwa kutariswa zvakanyanya. Mushumo wemusika weMarket Research Future wekugadzira zvinhu zvidiki , musika wepasi rose wekugadzira michina midiki waikosha pamadhora mabhiriyoni 8.26 muna 2024 uye unotarisirwa kusvika mabhiriyoni gumi nemashanu nemakumi masere nemaviri emadhora panosvika gore ra2035 . MuchiRungu chakajeka, vanhu vazhinji vari kutenga michina iyi, uye havasi vese vari kutenga nekuchenjera.
China zvakare chikamu chikuru chemufananidzo wezvinhu izvi. Ruzivo rwekutengeserana rweWITS rweWorld Bank rweHS 842952 zvinoratidza kuti United States yakatenga mayuniti 110,573 muchikamu ichi chekuchera muna 2024, kusanganisira mayuniti 29,353 kubva kuChina . Izvi hazvirevi kuti mayuniti ese ekuChina akanaka, uye hazvirevi kuti muchina wese wakachipa wakaipa. Zvinoreva kuti vatengi vanoda kuongororwa kwemhando yepamusoro vasati vabhadhara dhipoziti.
Chikanganiso chekutanga ndechekuenzanisa michina nemutengo chete. Mini excavator haisi chinhu chimwe chete chakasimbiswa. Caterpillar inotsanangura zvicherwa zvidiki semichina inotangira pasi pe 1 metric ton kusvika ku 10 metric ton , ine simba rekusimudza kubva pa 1,000 lb pama micro models kusvika pa 5,000 lb pama ma 8-10 ton models makuru. Iro ibasa guru. Muchina webindu nemuchina wekuchera trenching zvese zvinogona kunzi "mini excavators," asi hazvirarame hupenyu hwakafanana.
Usati wabvunza mutengo wakanakisa, tsanangura basa racho. Unofanira kuchera zvakadzama sei? Muchina uyu uchange uine muchina wekucheka matombo, muchina wekucheka matombo, muchina wekucheka matombo kana muchina wekucheka matombo here? Uchashanda here pavhu rakapfava, magedhi akaomarara, nzvimbo dzakatenuka kana mabasa ekurenda uko vanoushandisa vanogona kuubata neruoko rwakanaka sengoro yekutengera? Kana basa racho rava pachena, saizi yemuchina inotanga kunzwisisika.
Bhurocha remutengesi rinofanira kukupa nhamba dzinoyerwa, kwete zvipikiso zvine hushamwari chete. Kuti zvive nyore kushandisa, Peji rezvinotsanangurwa zveKati 301.8 ine simba remahp 21 , huremu hwekushanda hwe2,029 kg , kudzika kwekuchera kwe2,570 mm , kuyerera kwepombi ye66 L/min uye kumanikidzwa kwemidziyo yemabhawa 245. Mini excavator yekuChina iri mukirasi imwe chete ye1.8-2 ton haifanirwe kukopa nhamba idzodzo chaizvo, asi mutengesi anofanira kukwanisa kupa rudzi rumwe chete rwedata.
| Chinhu Chemhando Yepamusoro | Zvekukumbira | Nei Zvichikosha |
|---|---|---|
| Kurema kwekushanda | Huremu hwemuchina hwakazara nenjanji, mafuta uye denga/tekisi | Kugadzikana, huremu hwekutakura uye simba rekuchera zvinoenderana nazvo |
| Injini | Chiratidzo, modhi, simba remagetsi uye chiyero chekuburitsa mweya | Kusajeka kweinjini kunogona kukonzera matambudziko ebasa uye emitero |
| Sisitimu yeHydraulic | Kuyerera kwepombi, kuyerera kwekubatsira uye kumanikidzwa | Zvinosungirirwa zvinoda kuyerera kwakakodzera, kwete mapini akakodzera chete |
| Nzvimbo yekuchera | Chera kudzika, kusvika uye kukwirira kweduru | Zvinodzivirira kutenga muchina usingakwanise kusvika pabasa |
| Chifambiso chepasi pemotokari | Upamhi hwe track, maroller, ma sprockets uye ruzivo rwekupedzisira rwe drive | Nzvimbo iyi inowanzoita kuti pave nekubhadhara mari dzinodhura dzekugadzirisa |
| Rutsigiro rwezvikamu | Mafirita, mapombi, zvisimbiso, maroller nemamota | Muchina wakachipa hausi wakachipa kana zvikamu zvichitora mwedzi miviri |
Kana mutengesi akadzivisa nhamba idzi, deredza kumhanya. Mugadziri chaiye kana mutengesi anonyatsoda kutengesa kunze haafanire kutora mazuva matatu kuti awane huremu hwemuchina wake.
Injini inokwezva kutariswa nekuti vatengi vanoziva mazita emakambani. Izvozvo zvakanaka, asi sisitimu ye hydraulic ndiyo inosarudza kuti muchina wacho unonzwa sei chaizvo. Mini excavator ine hydraulic matching isina kunaka inogona kutaridzika zvakanaka mumifananidzo asi ichinzwa isina simba panzvimbo yacho. Boom inogona kusimuka zvishoma nezvishoma, ruoko runogona kuzeza, kana kuti attachment inogona kushanda sekunge yakadya masikati marefu.
Paunenge uchiongorora mini excavator yekuChina, enzanisa simba reinjini, kuyerera kwepombi, kumanikidzwa uye kugona kutonhora pamwe chete. Kana uchironga kushandisa breaker kana auger, bvunza assistant flow uye pressure, wobva waenzanisa nhamba idzodzo nezvinodiwa zvekubatanidza. Chiyero cheCat 301.8 che66 L/min pump flow uye 245 bar pressure chinopa vatengi nzvimbo inoshanda yekutarisa iyi muchina. Pasina data rekuyerera uye kumanikidzwa, hausi kuenzanisa michina chaizvo; uri kuenzanisa mavara ependi.
Muchitsiko chepasi pemotokari ndipo panodhura michina yakawanda "yakachipa" chinyararire. Caterpillar inotaura muchikamu chayo che "pasi pemotokari". nhungamiro yemuchina wekuchera pasi pechingoro kuti matambudziko ane chekuita nemotokari dziri pasi pemotokari anogona kumirira mari inopfuura hafu yekugadzirisa ma excavator . Nhamba iyoyo yoga ndiyo chikonzero chakakwana chekutarisa zvakanyanya ma tracks, ma rollers, ma sprockets uye ma final drives asati atumirwa.
Kumbira mifananidzo iri pedyo uye vhidhiyo iri kufamba. Nzira dzinofanira kugara dzakatwasuka, maroller haafanire kuratidza kubuda kwemvura pachena, uye madhiraivha ekupedzisira anofanira kuramba akaoma mushure mekunge muchina wadziya. Kana muchina uine chifambiso chepasi chinogona kuwedzerwa, edza nzvimbo dzese dziri mbiri. Unofanira kutsvedza zvakanaka usingabatanidzi. Kana uchifamba sedhirowa rine ngura, fungidzira kuti uchaita sei mushure memwedzi mitanhatu mumatope.
Kushongedza zvakanaka hakusi kungoshanda zvakanaka chete. Kunosanganisira kugara zvakanaka munzvimbo dzine dambudziko: chitsitsinho chetsoka, chisungo cheruoko, chisungo chebanga, chisungo cheswing uye frame yenzira. Tsvaga kana paine undercut, porosity, saizi yeweld isina kuenzana uye kukuya kunofungirwa. Pendi itsva inogona kuita kuti basa rakaoma ritaridzike zvakanaka kwenguva yakati, asi kudedera kune tsika yakaipa yekuburitsa zvakavanzika.
Magadzirirwo ekuchengetedza anodawo humbowo, kwete mashoko ekukurudzira. Cat 301.8 inonyora mitemo yakaita seROPS ISO 12117-2:2008 , TOPS ISO 12117:1997 uye Top Guard ISO 10262:1998 Level I pane zvayakaita pakugadzirwa kwayo. Kana mutengesi akati kabhini "yakachengeteka," bvunza kuti inoenderana nemutemo upi. Pamisika yekutengesera kunze kwenyika, mitemo yakanyorwa inonyanya kukosha kupfuura mashoko ane chivimbo.
Kutevedzera mitemo hakusi chinhu chidiki chinongodiwa nehutungamiriri. Kune michina yedhiziri inoenda kuUS, Mitemo yeUS EPA yeinjini dzedhiziri dzemidziyo inorema inovhara michina isiri yemumugwagwa yakaita sema excavator, uye EPA inoti dhiziri re sulfur rakaderera zvakanyanya rine huwandu hwakanyanya hwe sulfur hwe15 ppm . Vatengi vanofanira kutarisa label yeinjini, chitupa cheEPA uye invoice vasati vatumira, kwete mushure mekunge muchina wasvika kucustoms.
Kune vanotenga muEU, bhendi remagetsi einjini uye kutevedzera mitemo yeStage V zvinokosha. Mutemo weEU 2016/1628 inoisa miganhu yekuburitsa utsi hwemagetsi kune mainjini emuchina asingashande mumugwagwa, kusanganisira nzvimbo dzemagetsi dzakaoma dzekuchera. Kana mutengesi asingakwanise kutsanangura kana injini ichitevedzera EPA, CE kana Stage V, izvozvo hazvisi "nyaya diki yemapepa." Izvi zvinogona kukanganisa kuburitswa kwemagetsi, kukosha kwekutengesa zvakare uye kuvimba kwevatengi.
Kuongorora kwakakodzera kwemuchina usati watumira kunofanirwa kuratidza kuti muchina uri kushanda, kwete kungomira chete. Kumbira vhidhiyo inosanganisira kutanga kwakadzikama, kurara, kusimudza simba, kusimudza ruoko, kufamba kwebhaketi, kutenderera, kushanda kwebanga, kufamba munzira dzese uye kushanda kwehydraulic. Kufamba-famba kwemaminitsi maviri nemimhanzi inonakidza haisi bvunzo. Imakwikwi erunako rwemuchina.
| Nzvimbo Yekuyedza | Mugumisiro Wakanaka Unoita Sei |
|---|---|
| Kutanga kwakaoma | Inotanga isina utsi hwakawanda kana kukanda makumbo kakawanda |
| MaHydraulics | Kufamba zvakanaka kwebhomba, ruoko nebhaketi pasina kuzunza |
| Sisitimu yekushambira | Inotenderera mativi ese pasina kugogodza kana kunonoka |
| Sisitimu yekufamba | Nzira dzakatwasuka pasina kukuya kana kusvetuka |
| Madhiraivha ekupedzisira | Hapana mafuta anobuda mushure mekudziya |
| Sisitimu yemagetsi | Kuratidza, marambi, kuchaja uye maswichi ekuchengetedza zvinoshanda |
| Magwaro | Manhamba eserial, label yeinjini, invoice uye match packing list |
Muchina wekugadzira mudiki wekuChina wakanakisa hausi iwo wakachipa nguva dzose. Ndiwo muchina une zvirevo zvakajeka, mahydraulics akaenzana, pasi pemotokari yakasimba, magwaro anoteverwa uye zvikamu zvekuchengetedza zvaunogona kutenga gare gare. Mutengo unokosha, hongu. Hapana anofarira kubhadhara mari yekuwedzera yekushongedza chete. Asi mutengo unofanirwa kukubatsira kusarudza pakati pemichina yakakodzera, kwete kutsiva kuongorora.
Kana mutengesi akapa ruzivo rwakadzama, mavhidhiyo chaiwo ekuyedza, magwaro ekutevera mitemo uye rutsigiro rwezvikamu, dhiraivha diki rinobva kuChina rinogona kuva chishandiso chinoshanda kune vanogadzira zvivakwa, vanogadzira minda, mapurazi nemakambani ekurenda. Kana mutengesi akadzivisa nhamba, akachinja mhando dzeinjini pasina chiziviso, kana kuti asingakwanise kutsanangura kuyerera kwemvura, famba. Tsvina ine moyo murefu. Icharamba yakamirira kana wawana muchina wakakodzera.
