Nekuwedzera kuri kuita musika kudiwa kwezvigadzirwa zvepurasitiki, kukwidziridzwa kwejekiseni rekugadzira muchina michina iri kuwedzera nekukurumidza uye nekukurumidza. Machina ekutanga majekiseni ekuumba majekiseni ese aive hydraulic, uye mumakore achangopfuura kwave nekuwanda uye kuwanda kwemagetsi majekiseni ekuumba majekiseni.
Mushure mekunge China yabatana neWorld Trade Organisation (WTO), indasitiri yekugadzira michina yekunze yakamhanyisa kuendeswa kuChina. Mamwe makambani anozivikanwa emajekiseni ekuumba majekiseni pasi rose, akadai seGermany Demark, Krupp, Badenfeld, uye Sumitomo Heavy Industries, akatevedzana agara mu “China, vamwe vakawedzera kuseta tekinoroji nzvimbo. Kupinda kwevagadziri vejekiseni rekugadzira jekiseni rekunze kwakaunza simba kuindasitiri yemuchina wekugadzira jekiseni, uye panguva imwe chete, yakazadza mikana nematambudziko kune vanogadzira majekiseni emuchina weChinese.
Parizvino, zvigadzirwa zvemuchina wejekiseni weChina zvinonyanya kutariswa mune zvakajairika-chinangwa zvidiki uye zvepakati-saizi michina. Mumakore ekuma1980 nema1990, kupihwa kwezvigadzirwa zvepasi-pasi kwakapfuura kudiwa, kugona kwekugadzira kwakange kwakanyanyisa, uye kugona kwekambani kwakadzikira. Mimwe mhando, kunyanya super-chaiyo hombe-yepamusoro-yekupedzisira zvigadzirwa, zvichiri zvisina chinhu uye zvichiri kuda kutengwa kunze kwenyika. Maererano nenhamba dzemuna 2001, China yakatenga kunze michina yekuumba jekiseni ichishandisa mari yekunze inosvika bhiriyoni imwe nemazana maviri emadhora ekuAmerica, ukuwo michina yekuumba jekiseni kunze kwenyika yaiwana madhora miriyoni zana nemakumi matatu chete, uye kutengeswa kunze kwenyika kwakakura kudarika kutengeswa kunze kwenyika.
Iyo yese-hydraulic jekiseni yekuumba muchina ine akawanda akasiyana mabhenefiti mukuumba chaiyo uye yakaoma maumbirwo. Yakashanduka kubva kune yechinyakare single-cylinder liquid-filled and multi-cylinder liquid-filled type kune yazvino maviri-plate direct-pressure type, umo mahwendefa maviri anotsikirirwa zvakananga. Iyo inomiririra zvakanyanya, asi tekinoroji yekudzora yakaoma, iyo machining chaiyo yakakwira, uye iyo hydraulic tekinoroji yakaoma kugona.
Iyo yese-yemagetsi jekiseni molding muchina ine akatevedzana mabhenefiti, kunyanya maererano nekuchengetedza kwezvakatipoteredza uye kuchengetedza simba. Nekuda kweiyo yakanyanya kurongeka yejekiseni kutonga kwe servo mota, iyo yekutenderera inomhanyisa zvakare yakagadzikana, uye inogona kugadziridzwa mumatanho akawanda. Nekudaro, ese emagetsi majekiseni ekuumba majekiseni haana kusimba senge yakazara-hydraulic jekiseni yekuumba michina, nepo yakazara-hydraulic jekiseni yekuumba michina inofanirwa kushandisa servo mavharuvhu ane yakavharwa-loop control kuti ave nechokwadi, uye servo mavharuvhu anodhura uye anodhura.
Muchina wemagetsi-hydraulic jekiseni rekuumba muchina mutsva wekuumba jekiseni unobatanidza hydraulic nemagetsi drive. Iyo inosanganisa iyo yepamusoro-inoshanda uye yese-yemagetsi-ekuchengetedza simba mabhenefiti eiyo yakazara-hydraulic jekiseni molding muchina. Iyi yemagetsi-hydraulic yakasanganiswa jekiseni rekuumba muchina Yave nzira yekuvandudza yejekiseni yekuumba muchina tekinoroji. Indasitiri yekuumba jekiseni yakatarisana nemukana wekukurumidza wekusimudzira. Nekudaro, mumutengo wechimiro chezvigadzirwa zvekuumba jekiseni, mutengo wemagetsi unoverengera chikamu chikuru. Zvinoenderana nezvinodiwa zvemajekiseni ekuumba muchina wemidziyo process, jekiseni mota yepombi yepombi mota inoshandisa chikamu chikuru cheiyo yakazara midziyo yekushandisa simba. 50% -65%, saka ine mukana mukuru wekuchengetedza simba. Kugadzira uye kugadzira chizvarwa chitsva che "simba-rekuchengetedza" majekiseni ekuumba majekiseni chave chido chekukurumidzira chekuteerera nekugadzirisa matambudziko.
