Molemo ka ho fetisisa theko moetsi oa Closed tooth Roller Shell
- SHH.ZHENGYI
Khetla ea rolara ke e 'ngoe ea likarolo tse ka sehloohong tse sebetsang tsa leloala la pellet. E sebelisoa ho sebetsana le li-pellets tse fapaneng tsa biofuel, lijo tsa liphoofolo le li-pellets tse ling. Ho sebelisa tšepe ea alloy e phahameng e sa sebetseng (40Cr, 20Crmnti, Gcr15), kalafo ea mocheso oa carburizing, boima ba junifomo. Bophelo ba ts'ebeletso bo bolelele, 'me ho na le mefuta e fapaneng ea meaho e kang leino le bōpehileng joaloka leino, le thibiloe ka sebōpeho sa leino, le sebopeho sa lesoba. Karolo e hatellang e entsoe ka shaft e ka hare ea eccentric le likarolo tse ling tse nang le litekanyo tse nepahetseng, tse loketseng ho lokisa sebaka se pakeng tsa rolara e hatellang le selikalikoe se shoang ho latela litlhoko tsa tlhahiso ea mosebelisi, 'me ho bonolo ho mena le ho kenya, mme ho bonolo ho nka sebaka sa khetla ea rolara e hatellang.
Mehato ya tlhokomelo
1.Khetha ka nepo tekanyo e nepahetseng ea "die hole compression ratio".
2.Lokisa ka nepo lekhalo la ho sebetsa pakeng tsa lesale la ho shoa le "rolara ea khatello" ho ba pakeng tsa 0.1 le 0.3mm (motlakase oa khatello o khannoa ke selikalikoe ka mor'a hore granulator e ncha e bulehe ka "moea o kang oa ho potoloha empa o sa potoloha").
3.Sesepa se secha se lokela ho sebelisoa ka rolara e ncha ea khatello, 'me mochini oa khatello le mochini oa selikalikoe li tlameha ho lokoloha pele ebe li tiisa. Ha likhutlo tse bohale li hlaha ka mahlakoreng a mabeli a mochine oa khatello, flange ea mochine oa khatello e lokela ho lokisoa ka letsoho la letsoho ka nako e le hore ho be bonolo ho lumellana hantle pakeng tsa mochine oa khatello le lesale la shoa.
4.Thepa e tala e tlameha ho hloekisoa pele le karohano ea makenete ka pel'a pelletizer ho fokotsa khatello ea tšepe ka mokoting oa lefu. Le ho hlahloba lesoba khafetsa ho bona hore na ho na le blockage. Hlakola kapa o phumole lesoba le thibaneng la hlobo ka nako.
5.Plastiki deformation ea tataiso khoune lesoba ea lesale shoa lokela ho lokisoa. Ha ho lokisoa, hoa lokela ho hlokomeloa hore karolo e tlaase ka ho fetisisa ea karolo e ka hare e sebetsang ea lesale e lokela ho ba 2mm e phahameng ho feta tlase ea groove ea overtravel, 'me ho ntse ho e-na le sebaka sa ho lokisa sekontiri sa khatello ea khatello ka mor'a ho lokisoa Ho seng joalo, selikalikoe se lokela ho hlakoloa.
6.Khetla ea "rolara ea khatello" e entsoe ka lisebelisoa tsa alloy tse sa sebetseng ka ho sebetsa ka khauta le kalafo ea mocheso. Leino holim'a sebopeho sa khetla ea rolara ea khatello e na le tšusumetso e itseng ts'ebetsong ea granulation.
Ka tloaelo ho sebelisoa profil ea meno ea li-roller: profil ea leino ka mofuta, profil ea leino eseng ka mofuta, mofuta oa lesoba.
1.Li-roll le li-groove tsa meno li sebelisoa haholo-holo bakeng sa ho peta liphoofolo le thepa ea likhoho. Molemo oa li-rollers ke hore lesale la ring le apara ka tsela e tšoanang, empa ts'ebetso ea coil e fokola.
2.The tooth groove shape pressure roller e na le ts'ebetso e ntle ea coil 'me e sebelisoa hangata lifemeng tsa phepelo, empa ho roala ha reng ha se junifomo. The leino groove sebopeho khatello ea rolara le ho tiisoa bohale bohale haholo-holo a loketse bakeng sa pelletizing ea lintho tse phelang metsing. Thellela ka mahlakoreng a mabeli.
