Puʻupuʻu Needle Paʻi Kiʻekiʻe

ʻO ka High-Pressure Needle Valve Stem kahi ʻāpana hoʻokele pololei i hoʻolālā ʻia no nā mea kani a me nā noi valve kaʻina i helu ʻia a hiki i 6,000 PSI (414 bar). Hana ʻia e Ningbo Ruican me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe kālā i ka 17-4 PH precipitation-hardening stainless steel, hāʻawi kēia ʻāpana i ka hoʻopau ʻana i ka ʻili, ka pololei o ke kaula, a me ka pololei o ka noho conical i koi ʻia no ka pani ʻana i ka bubble-paʻa i ke koi ʻana i ka aila & kinoea, petrochemical, a me ka mana hana kaiapuni. ʻO ke kaʻina hana hoʻoheheʻe hoʻohui ʻia + CNC e hōʻoiaʻiʻo ana i ka hui ʻana o ka geometry stem ma hope o ka pūʻulu, koʻikoʻi no nā hiʻohiʻona kahe hou a me ke ola noho lōʻihi.

Nā mea kiko'ī

Kaʻina Hana Hana

1. ʻO ka Wax Pattern Injection : ʻO ka wai wax injection me ke kila make, conical tip i hana ʻia i ± 0.05mm
2. Hale Hana : 7-9 papa ʻāpana ʻeleʻele me ka ʻaʻahu kumu silica fused no ka hoʻopau ʻana o ka ʻili
3. ʻO ke ahi a me ke kī ʻana : Autoclave dewaxing ma 8 bar, ke kī ʻana i ka pūpū ma 950°C
4. Ka ninini ʻana : 17-4 PH ke kila kila i ninini ʻia ma 1560–1600 ° C ma lalo o ka argon shroud
5. Hoʻoponopono Hoʻoponopono : 1040 ° C no 1 hola, hoʻoluʻu ea
6. ʻO ka paʻakikī o ka ua (H1025) : 550°C no 4 mau hola, hoʻomaha ʻia ka ea
7. CNC Mīkini : ʻO ka huli ʻana o CNC o ka milo (M16 x 1.5), ka noho conical (20° me ke kihi, Ra 0.4), a me ke alakaʻi kumu.
8. Lapaʻau ʻili : Electropolishing a i ʻole passivation no ka ASTM A967
9. Nānā : CMM dimensional, ʻeleʻele o ka ʻili, ke komo ʻana o ka dye, hoʻāʻo paʻakikī

Nā mea nui

• Maikaʻi kiʻekiʻe : 17-4 PH loaʻa i ka 1070 MPa ikaika tensile a me 35-42 HRC paʻakikī, kūpono no 6,000 PSI i helu ʻia.
• Noho Conical Pono : 20° kihi cone i mīkini ʻia i Ra 0.4 µm, e hōʻoia ana i ka sila paʻa metala-a-metala.
• Ka pololei o ka Thread : M16 x 1.5 thread machined i ka 6g tolerance no ka hana maʻalahi me ka ʻole o ka backlash.
• Kū'ē Kū'ē : Hāʻawi ka Passivated 17-4 PH i ke kū'ē maikaʻi loa i ka H₂S, CO₂, a me ka chloride kaiapuni
• Hoʻopau i ka ʻili : Ra 0.8 µm ma nā ʻili e hoʻopaʻa ʻia, Ra 1.6 µm ma ke kino - kūpono no nā ʻanuʻu mea kani.
• NACE MR0175 Compliant : Loaʻa ma ke kūlana hoʻokō NACE no nā noi lawelawe ʻawaʻawa

Nā kahua noi

• ʻO nā kiwi kui kui (6,000 PSI papa)
• Kaʻina hana ʻana i nā ʻōkuhi nila no nā mea kanu petrochemical
• Hoʻopaʻa a hoʻokahe koko i nā manifolds
• ʻO nā pahu wai hoʻokaʻawale hydraulic kiʻekiʻe
• Pūnaehana hoʻoheheʻe ʻana i ka mana
• Hoʻokaʻawale kaʻina hana ma waho o ke kai

No ke aha e koho ai iā Ningbo Ruican

ʻO Ningbo Ruican ka ʻike hoʻolei waiwai i ka 17-4 PH stainless steel, i hui pū ʻia me nā ʻōnaehana maikaʻi IATF 16949, hāʻawi i nā ʻāpana valve e kūpono i nā koi API 602 a me ASME B16.34. ʻO kā mākou mīkini CNC i hoʻohui ʻia e hōʻoia i ka concentricity o ke kumu i loko o 0.02mm, koʻikoʻi no ke ola pōʻai valve. Hāʻawi mākou i ka palapala hōʻoia piha piha (3.1 EN 10204), palapala hoʻokō NACE, a me PPAP no ka hoʻolauna huahana hou.
