Njira Zopangira ndi Zopangira
Malinga ndi njira zosiyanasiyana zopangira, zitha kugawidwa m'machubu otentha okulungidwa, chubu chozizira chozizira, chubu chokoka ozizira, chubu cha extrusion ndi zina zotero.
1.1 Mipope yotentha yopanda msoko nthawi zambiri imapangidwa pamagetsi odzigudubuza okha.The olimba chubu akusoweka kufufuzidwa ndi chitakonzedwa zofooka pamwamba, kudula mu utali wofunika, centering pa perforated mapeto nkhope ya chubu akusowekapo, ndiyeno kutumizidwa ku ng'anjo Kutentha kwa kutentha, ndi perforated pa nkhonya makina.Mu perforation nthawi yomweyo mosalekeza kasinthasintha ndi patsogolo, pansi pa zochita za mpukutu ndi pamwamba, chubu opanda kanthu pang'onopang'ono anapanga patsekeke, wotchedwa ubweya chubu.Kenako imatumizidwa ku mphero ya chitoliro cha automatic kuti ipitilize kugudubuza.Potsirizira pake, makulidwe a khoma la makina onse amasinthidwa, ndipo makina opangira makina amasinthidwa kuti akwaniritse zofunikira.Ndi njira yotsogola yopangira chubu chachitsulo chosasunthika chotentha chokhala ndi chubu chopukutira mosalekeza.
1.2 Ngati mukufuna kupeza machubu opanda msoko okhala ndi kukula kocheperako komanso abwinoko, muyenera kugwiritsa ntchito kugudubuza kozizira, kujambula kozizira kapena kuphatikiza njira zonse ziwiri.Kuzizira kozizira nthawi zambiri kumachitika pa mphero ziwiri.Chitoliro chachitsulo chimakulungidwa mu chiphaso cha annular chokhala ndi groove yozungulira yokhala ndi gawo losinthika komanso nsonga yokhazikika ya conical.Kujambula kozizira nthawi zambiri kumachitika mu unyolo umodzi wa 0.5 ~ 100T kapena makina ojambulira ozizira awiri.
1.3.Njira yotulutsira: Chubu chotenthetsera chopanda kanthu chimayikidwa mu silinda yotsekedwa, ndipo ndodo ya perforated imasuntha pamodzi ndi ndodo ya extrusion kuti itulutse mbali zowonongeka kuchokera ku dzenje laling'ono lakufa.Njira imeneyi akhoza kupanga zing'onozing'ono m'mimba mwake zitsulo chitoliro.
Chitoliro Chachitsulo Cholondola, Gwiritsani Ntchito
