Kuphulika kwa Mchenga - Kolondola komanso Kosinthasintha

Kuphulitsa mchenga kumagwiritsa ntchito mpweya wopanikizika ngati mphamvu yayikulu yopopera zinthu zosakhazikika pa liwiro lalikulu pamwamba pa chinthu chogwirira ntchito. Malo ake oyambira ndi kuyeretsa + kupukuta bwino, ndi ntchito zina zowonjezera. Ndi njira yofunika kwambiri yochiritsira musanapopere ndi kupukuta ndi electroplating.

Mphamvu yake ikhoza kusinthidwa mosavuta: mphamvu ya mpweya yogwiritsira ntchito kuphulika kwa mchenga ndi 0.5–0.7 MPa, ndipo kuphulika kwa kupopera ndi 0.3–0.5 MPa. Kuphulika kothandizidwa ndi madzi (kuphulika konyowa) kungagwiritsidwe ntchito nthawi zina. Zida zolumikizirana zimaphatikizapo zinthu zosakhazikika monga mchenga wa quartz, alumina wofiirira, ndi zipolopolo za walnut zomwe sizimawononga chilengedwe. Kukula kwa tinthu tating'onoting'ono kumasankhidwa kutengera zofunikira pakukhwima kwa pamwamba; G120–G80 grit ikulimbikitsidwa kuti ichotse dzimbiri mu Sa2.5.

Cholinga chake chachikulu ndikuchotsa bwino mafuta, zokutira zakale, ndi dzimbiri pamwamba pa ntchito, kuwongolera bwino kuuma kwa pamwamba, ndikuwonjezera kumamatira kwa zokutira zina. Ingagwiritsidwenso ntchito popanga zojambula zaluso komanso kukonza zinthu zamagetsi popanda matte.

Ndi yoyenera ntchito zogwirira ntchito zazing'ono, zosiyanasiyana, komanso zovuta, monga nkhungu, zida za aluminiyamu zopyapyala, komanso kuchotsa dzimbiri m'malo osungiramo zinthu. Ndi yabwino kwambiri ku zitsulo zofewa ndi mapepala opyapyala kuti apewe kusinthika, ndipo imagwirizana ndi muyezo wa GB/T 8923.1 wochotsa dzimbiri.

Kuboola Mphuno - Molondola komanso Molunjika

Mofanana ndi kuphulika kwa mchenga pogwiritsa ntchito mphamvu, kupopera pogwiritsa ntchito mfuti kumagwiritsa ntchito mpweya wopanikizika kapena mphamvu yaying'ono ya centrifugal kuti ipopere zipolopolo zozungulira mofulumira kwambiri pamwamba pa workpiece. Imayang'ana kwambiri kulimbitsa pamwamba ndipo ndi yoyenera kuchiza madera ovuta.

Mphamvu yake imasinthasintha mosavuta, zomwe zimathandiza kuti pakhale kuwongolera kolondola kwa ngodya yopopera ndi liwiro la mfuti, zomwe zimapangitsa kuti ikhale yoyenera m'mabowo ovuta amkati ndi ngodya zomwe sizingaphimbidwe ndi mfuti. Zida zolumikizirana, zomwe zimagwiritsidwa ntchito powombera mfuti, ndi zozungulira zokhala ndi mainchesi a 0.1–2.0 mm. Zili ndi malo osalala, sizikanda kwambiri ntchito, ndipo zimatha kubwezeretsedwanso.

Ntchito yake yayikulu ndikuwonjezera kuuma kwa pamwamba, mphamvu ya kutopa, komanso kukana kuwonongeka kudzera mu ntchito yolimba, komanso kupereka njira zowongolera kupsinjika ndi kuchotsa matuza. Mphamvu yake yoyeretsa ndi yofooka poyerekeza ndi kuphulika kwa mchenga.

Zochitika zomwe zingagwiritsidwe ntchito zikuphatikizapo kulimbitsa zinthu zofunika kwambiri monga zida zamagalimoto, zida zoyendera ndege, ndi mabearing. Dziwani kuti zinthu zogwirira ntchito zokhala ndi mafuta pamwamba ziyenera kuchotsedwa mafuta pasadakhale kuti zisawononge ma shoti ndikusokoneza zotsatira zake.

Kuphulitsa Mfuti - Kuphatikizika ndi Kuchita Bwino

Kuphulitsa zipolopolo kumagwiritsa ntchito mphamvu ya makina yozungulira ngati mphamvu yaikulu. Impeller yozungulira mofulumira kwambiri (gudumu lophulika) imaponya zipolopolo zozungulira mwachangu kwambiri pamwamba pa chinthu chogwirira ntchito. Imayang'ana kwambiri pakuyeretsa bwino kwambiri + kulimbitsa malo, imakhala ndi automation yapamwamba kwambiri, ndipo ndiyo njira yabwino kwambiri yopangira zinthu zazikulu.

Ponena za mphamvu, liwiro la impeller limatha kufika pa 1500–3000 r/min, ndipo liwiro loyambirira la kuwombera ndi 100 m/s. Sichidalira compressor ya mpweya ndipo chimapereka chiŵerengero champhamvu cha mphamvu kuposa njira zina ziwiri zomwe zimagwiritsidwa ntchito kwa nthawi yayitali, ndipo mphamvu yake ndi yoposa 30% kuposa kuphulika kwa mchenga ndi manja. Zida zolumikizira ndi zozungulira, zopanda m'mphepete, zomwe nthawi zambiri zimakhala ndi chitsulo chopangidwa kapena chitsulo chosapanga dzimbiri, chokhala ndi mainchesi a 0.8–2.5 mm. Zitha kubwezeretsedwanso kambirimbiri, ndipo zimangofunika kubwezeretsanso nthawi zonse (kubwezeretsanso ≤ 10% ya voliyumu yonse).

Ntchito yake yayikulu ndikuchotsa oxide scale, kupanga mchenga, ndi dzimbiri kuchokera ku zinthu zotayidwa ndi zotayidwa, pomwe ikuwonjezera kuuma kwa pamwamba ndi kukana kutopa kudzera mu ntchito yolimba ndikuchepetsa kupsinjika kwamkati.

Zochitika zomwe zingagwiritsidwe ntchito makamaka ndi kuchuluka kwa zida zogwirira ntchito wamba, monga mbale zachitsulo, nsanja za mphepo, ndi zida zamagalimoto. Zitha kuphatikizidwa ndi mizere yoyendetsera yokha kuti ipangidwe mosalekeza, mogwirizana ndi miyezo ya zida za JB/T 8355 ndi muyezo wa GB/T 8923.1 wochotsa dzimbiri.

1. Kusiyana kwa Magwero a Mphamvu

• Kuphulika kwa Mchenga: Kumayendetsedwa makamaka ndi mpweya wopanikizika, wokhala ndi mpweya wosinthika kuti ugwirizane ndi zofunikira zosiyanasiyana zolondola.
• Kuboola Mphepete: Mphamvu yofanana ndi kuphulitsa mchenga; imagwiritsa ntchito mpweya wopanikizika kapena mphamvu yaying'ono ya centrifugal kuti ilamulire bwino.
• Kuphulika kwa Mfuti: Kumadalira mphamvu ya centrifugal yochokera ku impeller (mphamvu yamakina), sikufunika compressor ya mpweya, yokhala ndi mphamvu yokhazikika komanso yamphamvu.

2. Kusiyana kwa Cholinga Chachikulu

• Kuphulitsa Mchenga: Ntchito zazikulu ndi kuyeretsa pamwamba ndi kupukuta bwino monga chithandizo choyambirira cha kupopera ndi kupukuta ndi electroplating, ndi kuchotsa bowa.
• Kuboola Pachimake: Ntchito yaikulu ndi kulimbitsa pamwamba kuti pakhale kuuma komanso kukana kutopa; kuyeretsa kumakhala kofooka.
• Kuphulitsa Mfuti: Ntchito zazikulu ndi kuchotsa dzimbiri ndi oxide scale, komanso kulimbitsa pamwamba, zomwe zimagogomezera kugwira ntchito bwino kwambiri.

3. Kusiyana kwa Makhalidwe a Zofalitsa

• Kuphulitsa Mchenga: Imagwiritsa ntchito zinthu zosakhazikika, zakuthwa kwambiri (mchenga wa quartz, alumina wofiirira wosakanikirana, ndi zina zotero), zomwe sizingabwezeretsedwenso.
• Kuchotsa Minofu: Imagwiritsa ntchito zithunzi zozungulira zokhala ndi malo osalala omwe sakanda kwambiri zinthu zogwirira ntchito; imatha kubwezeretsedwanso.
• Kuphulitsa Zipolopolo: Chozungulira chofanana ndi kuphulitsa zipolopolo (zipolopolo zachitsulo, zipolopolo zachitsulo chosapanga dzimbiri, ndi zina zotero), ndi mphamvu yobwezeretsanso zinthu.

4. Kusiyana kwa Zochitika Zogwira Ntchito

• Kuphulika kwa Mchenga: Koyenera ntchito zogwirira ntchito zolondola zamagulu ang'onoang'ono, zosiyanasiyana, komanso zovuta (zoumba, zida za aluminiyamu zopyapyala).
• Kuboola Mfuti: Koyenera kugwiritsa ntchito mabowo ovuta amkati ndi ngodya zomwe sizingatheke kufikika ndi kuphulika kwa mfuti, makamaka pazida zonyamula katundu (magiya amagalimoto).
• Kuphulika kwa Mfuti: Koyenera kupanga zinthu zogwirira ntchito nthawi zambiri (mapepala achitsulo, nsanja za turbine ya mphepo), zogwirizana ndi mizere yopangira yokha.

5. Kusiyana kwa Zachilengedwe ndi Mtengo

• Kuphulika kwa Mchenga: Kumapanga fumbi lalikulu; zinthu zosagwiritsidwanso ntchito zobwezerezedwanso zimapangitsa kuti pakhale ndalama zambiri kwa nthawi yayitali.
• Kutulutsa zipolopolo: Kupanga fumbi pang'ono; zipolopolo zobwezerezedwanso, mtengo wake umakhala pakati pa kuphulika kwa mchenga ndi kuphulika kwa zipolopolo.
• Kuphulitsa Zipolopolo: Zipangizo zotsekedwa bwino zokhala ndi fumbi lochepa; kuchuluka kwa zinthu zobwezeretsanso zinthu zogwiritsidwanso ntchito, komanso mtengo wotsika kwambiri kwa nthawi yayitali.
