DIN/EN hydraulic precision steel tubes e etsoa ho latela DIN2391-C kapa EN10305-4 maemo, 'me maemo a ho fana hangata ke BK, NBK, GBK, joalo-joalo. Li-tubes tsa tšepe tse nepahetseng li sebelisoa haholo mekhoeng ea phetisetso ea matla e kang mechine ea kaho, liphaephe tsa chassis ea koloi, li-hydraulic system, le sistimi ea pneumatic.Li-hydraulic li arotsoe haholo ka mekhahlelo e meraro e latelang:
1. DIN/EN peipi ea tšepe e sa tsitsang e phahameng ka nepo e phahameng
Lisebelisoa tse tala li entsoe ka lisebelisoa tsa tšepe tsa boleng bo holimo tse tsoang Baosteel kapa Tiangang, tse hlatsoitsoeng ka acid, ho taka ka mokhoa o nepahetseng, kalafo ea mocheso o se nang oxidation (NBK state), tlhahlobo e sa senyeheng, ho hlatsuoa ka khatello e matla le ho hlatsoa acid ka hare. likoti tsa phala ea tšepe, phekolo ea thibelo ea mafome ea marako a ka hare le a ka ntle a phala ea tšepe e nang le oli e thibelang mafome, le phekolo ea ho thibela lerōle ka lipheletsong tse peli tsa sekoahelo.Liphaephe tsa tšepe tse hlahisoang li na le ho nepahala ho phahameng le boreleli bo botle.Ha ho na lera la oxide marakong a ka hare le a ka ntle a liphaephe tsa tšepe.
Liphaephe tsa tšepe li ka mamella khatello e phahameng ea phallo ea metsi, 'me liphaephe tsa tšepe ha li senyehe nakong ea ho kobeha ha serame.Li ka atolosoa, tsa batalatsoa, 'me ha li na mapetsong.Thepa ea mochini e ka kobeha ntle le deformation ho hang.Haholo-holo e sebelisetsoang ho lokisa liphaephe tsa tšepe ka har'a li-circuits tsa oli tsa hydraulic system, tse tsejoang hape e le liphaephe tse thata ka har'a li-hydraulic system, lipeipi tsa tšepe tse nepahetseng bakeng sa likoloi li ka fihlela litlhoko tsa bareki ka nepo e phahameng, boreleli bo phahameng, matla a thata, le thepa ea mochini bakeng sa lipeipi tsa tšepe.
2.DIN/EN peipi ea tšepe e entsoeng ka tšepe e phahameng ka ho nepahala
Ho sebelisoa liphaephe tsa tšepe tse hlakileng tse khanyang tse se nang seam bakeng sa electrogalvanizing, 'me marako a ka hare le a ka ntle a liphaephe tsa tšepe a koahetsoe ka zinki e mosehla (zinki ea' mala), zinki e tšoeu, phekolo ea passivation, le bolelele ba lipeipi tsa tšepe tse ka hare ho 6 metres. .Haholo-holo e sebelisoa liindastering tse kang liphaephe tsa tšepe tsa likoloi, tsamaiso ea liphaephe, lifofane, mechine ea temo le meru, mechine ea boenjiniere, likoloi tsa terene, likepe, joalo-joalo.
3. DIN/EN peipi ea tšepe ea phosphate e nepahetseng e phahameng haholo
Motheong oa ho sebelisa phala ea tšepe ea DIN2391/EN10305 e phahameng e hlakileng e khanyang e se nang seam, marako a ka hare le a ka ntle a peipi ea tšepe e hlakileng e entsoe ka phosphatized ka foromo ea phosphated agent dilution, ho etsa filimi e ntšo e sireletsang maboteng a kahare le kantle a tšepe. phala ho thibela mafome.Lipeipi tsa tšepe tsa phosphated tse ntšo li na le bokaholimo bo benyang bo botšo, 'mala o motle le ho hanyetsa mafome ka matla.Lipeipi tsa tšepe tsa phosphated tse nepahetseng haholo li sebelisoa haholo bakeng sa ho kenya liphaephe tsamaisong ea haeteroliki, hammoho le manonyeletso a ferrule (peipi ea tšepe) le manonyeletso a lipeipi tse cheselitsoeng.
