Ngokwezibalo, cishe u-70% wemishini yepulasitiki yaseChina ingumshini wokubumba umjovo. Ngokombono wamazwe amakhulu akhiqizayo anjenge-United States, iJapane, iJalimane, i-Italy, neCanada, ukukhiqizwa kwemishini yokubumba umjovo kuyanda unyaka nonyaka, kubalwa ingxenye enkulu yemishini yepulasitiki.
Ngokuthuthuka okusheshayo kwemakethe yokubumba yomjovo yaseChina, ukusetshenziswa kobuchwepheshe bokukhiqiza okuyisisekelo okuhlobene kanye nocwaningo nentuthuko kuzoba okugxilwe kakhulu embonini. Ukuqonda izitayela ze-R&D, imishini yokucubungula, ukusetshenziswa kobuchwepheshe kanye nezitayela zobuchwepheshe obuyisisekelo bokubumba umjovo ekhaya naphesheya kubalulekile ezinkampanini ukuthi zithuthukise ukucaciswa kwemikhiqizo futhi zithuthukise ukuncintisana kwemakethe.
Embonini yokubumba umjovo, ngo-2006, ingxenye yesikhunta somjovo yakhula futhi, izinga lesikhunta esigijimayo esishisayo kanye nokubunjwa okusizwa ngegesi lathuthuka lathuthuka, futhi ukubumba komjovo kwathuthuka ngokushesha ngokwenani nekhwalithi. Isethi enkulu kunazo zonke zokukhunta umjovo eShayina idlule amathani angama-50. Ukunemba kwezibumbe zokujova ezinembe kunawo wonke sekufinyelele kuma-microns angu-2. Ngesikhathi esifanayo lapho ubuchwepheshe be-CAD/CAM buthandwa khona, ubuchwepheshe be-CAE buya ngokuya busetshenziswa kabanzi.
Ekukhiqizeni kwamanje, ingcindezi yomjovo cishe yayo yonke imishini yokujova isuselwe engcindezini ekhishwa i-plunger noma phezulu kwesikulufu kupulasitiki. Ukucindezela komjovo enqubweni yokubunjwa komjovo ukunqoba ukumelana nokunyakaza kwepulasitiki kusuka emgqonyeni kuya emgodini, isivinini sokugcwalisa ukuncibilika kanye nokuhlanganiswa kokuncibilika.
Umshini wokubumba umjovo ukonga amandla, ukonga izindleko kuyisihluthulelo
Umshini wokubumba umjovo uyinhlobonhlobo enkulu yemishini yepulasitiki ekhiqizwa futhi isetshenziswe eShayina, futhi iphinde ibe ngumsizi wokuthunyelwa kwemishini yepulasitiki yaseChina. Ngasekupheleni kwawo-1950, umshini wokuqala wokubumba umjovo wakhiqizwa eChina. Kodwa-ke, ngenxa yokuqukethwe okuphansi kobuchwepheshe bemishini ngaleso sikhathi, kwakungenzeka ukusebenzisa amapulasitiki enhloso evamile ukukhiqiza izidingo zansuku zonke ezifana namabhokisi epulasitiki, izigubhu zepulasitiki nezimbiza zepulasitiki. Ubuchwepheshe bokubumba umjovo buthuthuke ngokushesha e-China, futhi ubuchwepheshe obusha nemishini emisha kuvela ngokulandelana. Ikhompyutha i-othomathikhi kakhulu. Ukuzenzakalela, ukusebenza okuningi komshini owodwa, okokusiza okuhlukene, inhlanganisela esheshayo, kanye nokufakwa kalula nokulungiswa kuzoba yinjwayelo.
Uma unciphisa ukusetshenziswa kwamandla kwemishini yokubumba umjovo, awukwazi ukunciphisa kuphela izindleko zezinkampani zomshini wokubumba umjovo, kodwa futhi unikele ekuvikelweni kwemvelo yasekhaya. Imboni ikholelwa ukuthi imikhiqizo yomshini wokubumba umjovo ewonga amandla futhi ephephile inendima ebalulekile nomthelela omuhle ekukhuthazeni ukuguqulwa nokuthuthukiswa kwemboni yemishini yepulasitiki yaseChina kanye nokwakha isakhiwo sezimboni esisha.
Imishini yepulasitiki yendabuko nayo inamandla athile ngokonga amandla, ngoba imiklamo yangaphambilini ivame ukugxila kuphela kumthamo wokukhiqiza womshini owodwa. Ekwakhiweni kwemishini yepulasitiki yokonga amandla, isivinini sokukhiqiza asiyona inkomba ebaluleke kakhulu, inkomba ebaluleke kakhulu ukusetshenziswa kwamandla kokucubungula imikhiqizo yesisindo seyunithi. Ngakho-ke, ukwakheka komshini, imodi yokulawula, kanye nezimo zenqubo yokusebenza kwezisetshenziswa kufanele zilungiselelwe ngokusekelwe ekusetshenzisweni kwamandla okuncane.
Njengamanje, ukonga amandla emkhakheni wemishini yokubumba umjovo e-Dongguan kunezindlela ezimbili ezivuthiwe ze-inverter kanye ne-servo motor, futhi ama-servo motors amukelwa kabanzi. Umshini wokubumba umjovo wochungechunge lokonga amandla we-Servo ufakwe ngesistimu yokulawula isivinini esishintshashintshayo se-servo esebenza kakhulu. Ngesikhathi senqubo yokubumba yomshini wokubumba umjovo, okukhipha imvamisa okuhlukile kwenzelwa ukugeleza kwengcindezi ehlukene, futhi ukulawulwa okuqondile kwe-loop okuvaliwe kokugeleza kwengcindezi kuyabonakala ukuze kubonwe i-servo motor ekubunjweni komjovo. Ukusabela kwesivinini esikhulu nokumatanisa okuphelele nokulungiswa okuzenzakalelayo kwezidingo zokonga amandla.
Umshini wokubumba umjovo ojwayelekile usebenzisa iphampu engaguquki ukunikeza uwoyela. Izenzo ezihlukahlukene zenqubo yokubumba umjovo zinezidingo ezahlukene zejubane nokucindezela. Isebenzisa i-valve yokulingana yomshini wokubumba umjovo ukulungisa uwoyela oweqile ngomugqa wokubuya. Ukubuyela ethangini likaphethiloli, ijubane lokujikeleza kwemoto lihlala njalo kuyo yonke inqubo, ngakho-ke inani lokunikezwa kukawoyela nalo lilungisiwe, futhi njengoba isenzo sokubulala singesinye isikhathi, akunakwenzeka ukuthi sibe nomthwalo ogcwele, ngakho-ke ukunikezwa kukawoyela kwenani enkulu kakhulu. Isikhala esimoshiwe silinganiselwa okungenani sibe ngu-35-50%.
I-Servo motor ihloselwe lesi sikhala sokulahlwa, ukutholwa kwesikhathi sangempela kwengcindezi elinganayo kanye nesignali yokugeleza okulinganayo kusuka ohlelweni lokulawula izinombolo lomshini wokubumba umjovo, ukulungiswa okufika ngesikhathi kwejubane lemoto (okungukuthi umthetho wokugeleza) odingekayo esimweni ngasinye sokusebenza, ukuze ukugeleza kokupompa kanye nokucindezela, Okwanele ukuhlangabezana nezidingo zesistimu, futhi esimweni esingasebenzi, vumela injini imise ukusebenza, ukuze indawo yokonga amandla iqhubeke yanda, ngakho-ke ukuguqulwa kokulondoloza amandla kwe-servo umshini wokubumba ungaletha umphumela omuhle wokonga amandla.
Ezinye izeluleko zezinkampani zomshini wokubumba umjovo
Okokuqala nje, kufanele sisungule isu lokuthuthukisa eligxile ekuthumeleni kwamanye amazwe, sikhulise ngamandla ukuthunyelwa kwempahla kwamanye amazwe, futhi sakhe izimo zokuthi imikhiqizo yethu ingene emakethe yamazwe ngamazwe. Ikakhulukazi, imikhiqizo ephezulu kufanele iqinise imizamo yokuthekelisa futhi ikhulise isabelo semakethe. Khuthaza amabhizinisi amaningi ukuthi aye ezikhungweni zocwaningo lwe-peripherals, amabhizinisi, ikakhulukazi iNingizimu-mpumalanga ye-Asia, iMpumalanga Ephakathi, i-Afrika, iRussia kanye neMpumalanga Yurophu anamandla amakhulu.
