Chengdu Zhengheng Power Parts Co., Ltd., kuburikidza netsvagiridzo yehunyanzvi hwekuita ejini hombe yedhiziri mune ramangwana, inonyatsoziva kuti fuselage yakasanganiswa silinda block uye silinda musoro wakabatanidzwa dhizaini (monoblock) injini ichave iyo nzira huru. uye tekinoroji kutungamira kweinorema-basa dhiziri injini yemuchina wekuvaka mune ramangwana nekuda kwemabhenefiti ayo akasiyana.

Zvakanakira fuselage conjoined injini ndezvi:

1. Wedzera simba kune theoretical yakanyanyisa kukosha;

2. Kuvandudza zvakanyanya kugadzirwa kweinjini uye kupfupisa kutenderera kwechigadzirwa;

3. Ukuru hwechigadzirwa chejini compact, iyo self weight inoderedzwa, iyo inobatsira zvikuru kuungana uye kugadzira;

4. Kuvandudzwa kwekuvimbika uye kuwedzera nguva dzekugadzirisa.

Kubva 2012, Chengdu Zhengheng Power Parts Co., Ltd. yakaisa R & D simba uye mari yekudzidza yekukanda uye machining tekinoroji yecast iron cylinder block inoshandiswa mu fuselage yakabatanidzwa injini.

Izvo zvigadzirwa zvekuvandudza zvigadzirwa zve cylinder block uye cylinder musoro wakabatanidzwa injini cylinder block zvinosanganisira:

1. Magadzirirwo akaomarara:

Nemhaka yekuti cylinder block uye cylinder head inoumbwa nekamwe-nguva yekukanda, chimiro chezvigadzirwa chakanyanya kuoma kupfuura icho chekukanda imwe chete cylinder block kana cylinder head;Mukuwedzera, mukugadzirisa kwemashure ekucheneswa kwecastings, zvinyorwa uye zvishandiso hazvikwanise kusvika zvakananga kune yakaoma yemukati maburi maburi;

2. Kukandira kwakaoma:

Huwandu hwe cylinder hole jecha musimboti, bhachi remvura musimboti uye mafuta duct core yakasungirirwa mukuvharwa kwebhokisi inodarika zvakapetwa kaviri iyo yekutanga yekukanda maitiro, iyo geometric nhanho yekuomerwa inowedzera, uye zvinodikanwa zvejecha core simba uye kurongeka. dzakakwirira;

3. Ukobvu hwemadziro hwakanyanya:

Iyo yakaderera madziro emadziro ekukanda ndeye 3.5mm, uye ukuru hwemadziro uhwu hunoitika kanopfuura ka4, iyo ine zvakanyanya zvakanyanya zvinodiwa pakurongeka kwemushini wekuumba uye kusimba uye kunaka kwejecha core;

4. Yakaoma kugadzirisa:

Kunyanya mukugadzirisa kwekudya uye kupera simba kwezvigaro zvemhete nemakomba silinda, Zhengheng simba rakapedza kugadzirwa kwechigadzirwa kuburikidza nehunyanzvi hwekuita tekinoroji, uye mhando yezvikamu zvakakosha zviri nani pane izvo muEurope.

Mushure meinoda kusvika hafu yegore yekutsvagisa nekusimudzira, simba reZhengheng rakabudirira kugadzira fuselage yakasanganiswa injini block (monoblock) muna 2013, ine hunyanzvi hwekutsvagisa nekugadzira inorema injini yedhiziri yemakina einjiniya epamusoro.Pakupera kwa2013, simba reZhengheng rakasvika mukushandira pamwe nemakambani epamusoro einjini muEurope uye akatanga nhevedzano yemasilinda maviri nemasilinda mana anodhura-inoshanda fuselage yakasanganiswa injini dzedhiziri dzakakodzera musika weChina.
