Kupera ndi njira yomaliza yomwe imagwiritsidwa ntchito kwambiri potseka pamwamba pa ma valve popanga. Kupera kungapangitse kuti pamwamba pa valve pakhale kulondola kwakukulu, kukhwima kwa mawonekedwe a geometric ndi kukhwima kwa pamwamba, koma sikungawongolere kulondola kwa malo pakati pa pamwamba pa valve. Kulondola kwa malo otsekera pansi nthawi zambiri kumakhala 0.001 ~ 0.003mm; kulondola kwa mawonekedwe a geometric (monga kusalingana) ndi 0.001mm; kukhwima kwa pamwamba ndi 0.1 ~ 0.008.
Mfundo yaikulu yotsekera pamwamba pa kugaya imaphatikizapo zinthu zisanu: njira yopera, kuyenda kwa kugaya, liwiro la kugaya, kupanikizika kwa kugaya ndi gawo logaya.
1. Njira yopera
Chida chopukusira ndi pamwamba pa mphete yotsekera zimagwirizanitsidwa bwino, ndipo chida chopukusira chimapanga mayendedwe ovuta opukira pamwamba pa malo olumikizirana. Zopukusira zimayikidwa pakati pa chida cholumikizira ndi pamwamba pa mphete yotsekera. Pamene chida cholumikizira ndi pamwamba pa mphete yotsekera zisuntha moyandikana, gawo la tinthu tating'onoting'ono tomwe tili mu chopukusira lidzatsetsereka kapena kugubuduzika pakati pa chida cholumikizira ndi pamwamba pa mphete yotsekera. Nsonga pamwamba pa mphete yotsekera zimachotsedwa poyamba, kenako mawonekedwe ofunikira amakwaniritsidwa pang'onopang'ono.
Kupera sikuti ndi njira yokha yopangira zinthu zopopera pa zitsulo, komanso ndi njira ya mankhwala. Mafuta omwe ali mu chopopera amatha kupanga filimu ya oxide pamwamba kuti ikonzedwe, motero kufulumizitsa njira yopera.
2 . kayendedwe kopera
Pamene chida chopukusira ndi pamwamba pa mphete yotsekera zikuyenda molingana, kuchuluka kwa njira zotsetsereka za mfundo iliyonse pamwamba pa mphete yotsekera kupita ku chida choperekera kuyenera kukhala kofanana. Komanso, njira yoyendera iyenera kusintha nthawi zonse. Kusintha kosalekeza kwa njira yoyendera kumalepheretsa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono kuti tisabwererenso njira yake pamwamba pa mphete yotsekera, kuti tisawononge zizindikiro zoonekeratu ndikuwonjezera kukhwima kwa pamwamba pa mphete yotsekera. Kuphatikiza apo, kusintha kosalekeza kwa njira yoyendera sikungapangitse kuti chopukusira chigawike mofanana, kotero kuti chitsulo pamwamba pa mphete yotsekera chingathe kudulidwa mofanana.
Ngakhale kuti kayendedwe ka kugaya ndi kovuta ndipo njira yoyendetsera imasintha kwambiri, kayendetsedwe ka kugaya nthawi zonse kamachitika pamwamba pa chida chogayira ndi pamwamba pa mphete yotsekera. Kaya ndi kugaya pamanja kapena kugayira kwamakina, kulondola kwa mawonekedwe a mphete yotsekera kumakhudzidwa kwambiri ndi kulondola kwa mawonekedwe a chida chogayira ndi kayendetsedwe ka kugaya.
3. liwiro lopera
Kupera kofulumira, kupera kogwira mtima kwambiri. Kuthamanga kopera kumakhala kofulumira, tinthu tambiri tomwe timadutsa pamwamba pa chinthu chogwirira ntchito pa nthawi iliyonse, ndipo chitsulo chochuluka chimadulidwa.
Liwiro lopera nthawi zambiri limakhala 10 ~ 240m/min. Pazida zogwirira ntchito zomwe zimafuna kupeta molondola kwambiri, liwiro lopera nthawi zambiri silipitirira 30m/min. Liwiro lopera pamwamba pa valavu limakhudzana ndi zinthu zomwe zili pamwamba pa valavu. Liwiro lopera pamwamba pa valavu yotseka ndi mkuwa ndi chitsulo chosungunula ndi 10 ~ 45m/min; pamwamba pa chitsulo cholimba ndi aloyi wolimba ndi 25 ~ 80m/min; pamwamba pa chitsulo chosapanga dzimbiri cha austenitic ndi 10 ~ 25m/min.
4. kupanikizika kopera
Mphamvu yopera imawonjezeka ndi kuchuluka kwa mphamvu yopera, ndipo mphamvu yopera siyenera kukhala yokwera kwambiri, nthawi zambiri 0.01-0.4MPa.
Mukapera pamwamba pa chitsulo chosungunuka, mkuwa ndi chitsulo chosapanga dzimbiri cha austenitic, mphamvu yopera ndi 0.1 ~ 0.3MPa; pamwamba pa chitsulo cholimba ndi aloyi wolimba ndi 0.15 ~ 0.4MPa. Tengani mtengo waukulu pa kugaya kosalala ndi mtengo wocheperapo pa kugaya kosalala.
5. Ndalama zopukutira
Popeza kugaya ndi njira yomaliza, kuchuluka kwa kudula kumakhala kochepa kwambiri. Kukula kwa gawo logaya kumadalira kulondola kwa makina ndi kukhwima kwa pamwamba pa ntchito yapitayi. Pansi pa mfundo yotsimikizira kuchotsa zizindikiro za ntchito yapitayi ndikukonza cholakwika cha geometric cha mphete yotsekera, gawo logaya likakhala laling'ono, ndibwino.
Malo otsekera nthawi zambiri ayenera kuphwanyidwa bwino musanapere. Mukapera bwino, malo otsekera amatha kulumikizidwa mwachindunji, ndipo gawo locheperako la kugaya ndi: gawo la m'mimba mwake ndi 0.008 ~ 0.020mm; gawo loyambira ndi 0.006 ~ 0.015mm. Tengani mtengo wochepa pamene kupeta ndi manja kapena kuuma kwa zinthu kuli kwakukulu, ndipo tengani mtengo wokwera pamene kupeta ndi makina kapena kuuma kwa zinthu kuli kochepa.
Malo otsekera a thupi la valavu ndi ovuta kuphwanyidwa ndikukonzedwa, kotero kutembenuza pang'ono kungagwiritsidwe ntchito. Mukamaliza kutembenuza, malo otsekera ayenera kukhala osalala musanamalize, ndipo gawo lozungulira ndi 0.012 ~ 0.050mm.
Tianjin tanggu water-seal valve Co., Ltd idapangidwa mwapadera popangavalavu ya gulugufe yokhazikika yolimba, valavu ya chipata, Chotsukira cha Y, valavu yolinganiza, valavu yoyezera wafer, ndi zina zotero.
Nthawi yotumizira: Juni-25-2023
