Chubu Chokongoletsedwa Chopangidwa Mwamakonda
01
Machubu Oyeretsedwa a ASTM A519 4140 a Hydraulic Cylinder
Chiyambi cha Zamalonda
JINYO ndi kampani yopanga zinthu zomwe zimagwiritsa ntchito kafukufuku ndi chitukuko, kupanga, kugulitsa ndi ntchito. Bizinesi yake imagwira ntchito yogawa ma hydraulic transmission, mapaipi achitsulo olondola komanso zida zina zamakina. Kampaniyo imagwiritsa ntchito ukadaulo wapamwamba wopangira makina opukutira ndi kupukutira, ili ndi luso lapadera lopanga ndi kukonza machubu a hydraulic cylinder, machubu opukutidwa ndi zinthu zopangidwa ndi ndodo ya piston yokhala ndi chrome, ndipo yadzipereka kupereka miyezo yapamwamba kwambiri komanso ntchito yabwino kwambiri padziko lonse lapansi.
Chitsulo chachitsulo chosapindika cha ASTM A519 4140 Chokongoletsedwa cha Hydraulic Cylinder
JINYO ili ndi machubu ambiri opukutidwa (mkati mwake opukutidwa) opangira ma silinda a hydraulic apamwamba kwambiri. Timapereka machubu opukutidwa a ASTM A519 4140 opangidwa mwapadera a Hydraulic Cylinders, omwe amagwiritsidwa ntchito kwambiri mumakina a hydraulic.
Machubu Opangidwa ndi Millimeter
Machubu Okhala ndi Inchi
Machubu Oyeretsedwa H8 H9
ZOFUNIKA:
·Chitsulo cha Giredi: STKM13C, ST52, SAE1020, C20, E355(ST52), SAE1026,4140, SUS304/316
·Kulondola kwa M'mimba mwake: H8 H9
·Kukhwima Kwamkati: Max Ra 0.2 μm
·Kulimba: 1-1.2/1000 mm
·Utali Wamba: 3M-9M
·Mulifupi wamkati: φ30- φ400
·Mafotokozedwe ena angaperekedwe ngati muwapempha (Chizindikiro Chapamwamba: 1000 mm)
Ntchito Zogwirizana ndi Makonda
JINYO ndi malo opangira zinthu apamwamba ndipo timagwiritsa ntchito ukadaulo wapamwamba wopanga zinthu komanso njira zowongolera khalidwe kuti tiwonetsetse kuti chubu chilichonse chokongoletsedwa chikukwaniritsa miyezo yathu yokhwima yaubwino. Kuyambira kusankha zinthu mpaka kuwunika komaliza, tadzipereka kupereka machubu okongoletsedwa omwe nthawi zonse amaposa zomwe makasitomala athu amayembekezera.
JINYO ili ndi zomangamanga zonse komanso gulu laukadaulo, ndipo kuwonjezera pa kupereka machubu oyeretsera kukula koyenera, ingathenso Sinthani machubu oyeretsera. Ntchito zathu zomwe timazipanga zimaphimba mbali zonse kuyambira pakupanga, kupanga mpaka kukonza zinthu, ndipo timatha kupereka mayankho omwe makasitomala amafuna. Mwachidule, machubu athu opukutidwa ndi abwino kwambiri pakugwiritsa ntchito ma silinda a hydraulic ndipo tadzipereka kupatsa makasitomala zida zodziwika bwino komanso zodalirika kwambiri za makina a hydraulic.

Zinthu Zamalonda
Machubu Oyeretsedwa Machubu achitsulo oyeretsedwa pansi amapangidwa mwaluso kwambiri komanso amasefedwa kuti akwaniritse zofunikira kwambiri pakulondola kwambiri, magwiridwe antchito komanso kudalirika mumakina a hydraulic. Machubu oyeretsedwa ndi abwino kwambiri kugwiritsa ntchito omwe amafunikira chubu chokhala ndi malo opukutidwa mpaka milimita, makamaka popanga masilinda a hydraulic okhala ndi mphamvu yayikulu.
Chubu choyeretsedwa chili ndi miyeso iwiri, millimeter ndi mainchesi.
Machubu oyeretsedwa amapangidwa kuti akwaniritse zofunikira zinazake, kuphatikizapo:
Zipangizo: chubu chokongoletsedwa zinthu zomwe zimagwiritsidwa ntchito kwambiri zimaphatikizapo zitsulo za kaboni monga ST52, AISI 1020, ndi zitsulo za alloy monga AISI 4140 ndi 42CrMo.
Kukula: Machubu opukutidwa amapezeka m'mitundu yosiyanasiyana, ndipo mainchesi amkati amakhala kuyambira 20mm mpaka 1000mm ndipo kutalika kwake kumafika mamita 12.
Miyezo Yolekerera: chubu chokwezedwa Miyezo yolekerera yapadziko lonse lapansi monga DIN2391, EN10305, ndi ASTM A519 imatsatiridwa kuti zitsimikizire miyezo yapadziko lonse lapansi.
Kukhwima kwa Pamwamba: Machubu opukutidwa ali ndi kukhwima kwa pamwamba pakati pa 0.2-0.4 um, koyenera kugwiritsidwa ntchito pofunikira malo osalala.
Magiredi Olekerera Mkati: chubu chokonzedwa Magiredi olekerera mkati mwa H8, ndi H9 ndi otheka, akukwaniritsa zofunikira zenizeni zoyenerera makina ndi zida zosiyanasiyana.
