Izindaba

I-DIN/EN hydraulic precision steel tubes akhiqizwa ngokuvumelana nezindinganiso ze-DIN2391-C noma EN10305-4, futhi izimo zokulethwa ngokuvamile ziyi-BK, NBK, GBK, njll. Amashubhu ensimbi enembile asetshenziswa kakhulu ezinhlelweni zokudlulisa amandla njengemishini yokwakha, amapayipi we-chassis yezimoto, amasistimu we-hydraulic, nezinhlelo zomoya.Ama-hydraulic ahlukaniswe kakhulu ngezigaba ezintathu ezilandelayo:

1. I-DIN/EN ipayipi yensimbi engenamthungo enembayo ephezulu enembayo

Izinto zokusetshenziswa zenziwe ngezinto ezisezingeni eliphezulu ze-carbon steel ezivela e-Baosteel noma e-Tiangang, ezihlanzwe nge-asidi, ukudweba okunembayo, ukwelashwa kokushisa okukhanyayo okungeyona i-oxidation (isifunda se-NBK), ukuhlolwa okungabhubhisi, ukushaywa kwengcindezi ephezulu kanye nokugeza i-asidi ngaphakathi. izimbobo zepayipi lensimbi, ukwelashwa kokuvimbela ukugqwala kwezindonga zangaphakathi nangaphandle zepayipi lensimbi ngamafutha angagqwali, kanye nokwelashwa kokuvimbela uthuli ngazo zombili iziphetho zekhava.Amapayipi ensimbi akhiqizwayo anokunemba okuphezulu nokushelela okuhle.Alukho ungqimba lwe-oxide ezindongeni zangaphakathi nezingaphandle zamapayipi ensimbi.

Amapayipi ensimbi angakwazi ukumelana nokucindezela okukhulu kokugeleza kwamanzi, futhi amapayipi ensimbi awaguquki ngesikhathi sokugoba okubandayo.Anganwetshwa, abe isicaba, futhi angabi nemifantu.Izakhiwo zemishini zingagotshwa ngaphandle kokuguqulwa kunoma iyiphi i-engeli.Ikakhulukazi esetshenziselwa ukulungisa amapayipi ensimbi kumasekethe kawoyela wesistimu ye-hydraulic, eyaziwa nangokuthi amapayipi aqinile ezinhlelweni ezisebenza ngogesi, amapayipi ensimbi anembayo ezimoto angahlangabezana nezidingo zamakhasimende ngokunemba okuphezulu, ukushelela okuphezulu, amandla aqinile, kanye nezakhiwo zemishini zamapayipi ensimbi.

2.DIN/EN ukunemba okuphezulu okunembayo kwepayipi lensimbi

Amapayipi ensimbi angenamthungo aphakeme anembayo aphezulu asetshenziselwa i-electrogalvanizing, futhi izindonga zangaphakathi nangaphandle zamapayipi ensimbi zimbozwe nge-zinc ephuzi (i-zinc yombala), i-zinc emhlophe, ukwelashwa kwe-passivation, nobude bamapayipi ensimbi angaba ngamamitha ayi-6. .Isetshenziswa kakhulu ezimbonini ezifana namapayipi ensimbi ezimoto, izinhlelo zamapayipi, izindiza, imishini yezolimo neyamahlathi, imishini yobunjiniyela, izimoto zikaloliwe, imikhumbi, njll.

3. I-DIN/EN ipayipi lensimbi le-phosphate elinembe kakhulu

Ngesisekelo sokusebenzisa i-DIN2391/EN10305 ipayipi lensimbi elingenamthungo elinembayo eliphakeme, izindonga zangaphakathi nezingaphandle zepayipi lensimbi elicace ngokunemba zifakwe i-phosphatized ngefomula ye-phosphated agent dilution, zakha ifilimu yokuvikela emnyama ezindongeni zangaphakathi nezingaphandle zensimbi. ipayipi ukuvimbela ukugqwala.Amapayipi ensimbi amnyama ane-phosphated anobuso obumnyama obucwebezelayo, umbala omuhle kanye nokumelana nokugqwala okuqinile.Amapayipi ensimbi ane-phosphated anembe kakhulu asetshenziswa kakhulu ekufakweni kwamapayipi ezinhlelweni ezisebenza ngamanzi, kanye nasemajoyini e-ferrule (amapayipi ensimbi) namajoyinti epayipi ensimbi ashiselwe.
