ʻOi aku ka makemake o ka mīkini ʻo Monel 400 ma mua o nā protocols stainless steel maʻamau - pono ia i ka mahalo i kona ʻano paʻakikī o ka hana, nā quirks conductivity thermal, a me ka abrasiveness. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ua hana mākou ma luna o 12,000 kg o nā ʻāpana Monel 400 mai ka makahiki 2020 - nā ʻūhā kaomi no nā manifold hydraulic subsea, nā hale pahu pahu piston pump no nā ʻāpana haʻihaʻi kiʻekiʻe, a me nā ʻāpana maʻamau o AMS 5387-compatible cyclic mau ʻāpana cyclic loading 350. hiki ole ke kukakuka. ʻO ka mea a mākou i aʻo ai, ʻaʻole ia he kumu. Hoʻopili ʻia ia i loko o nā hiʻohiʻona ʻaʻahu mea hana, ka nānā pono ʻana o ka ʻili, a me ka ʻae ʻana i ka ʻatikala mua ma waena o nā OEM o ʻAmelika ʻAmelika.
E hoʻomaka me ka Geometry Mea Hana Pono—ʻAʻole i nā uhi paʻakikī wale nō
Nui nā hale kūʻai i hoʻokomo i nā mea hoʻokomo carbide paʻa kiʻekiʻe kiʻekiʻe loa i ka wā e hoʻoponopono ai i ka mīkini Monel 400. Akā, ua ʻike mākou ʻaʻole i hāʻule nā mea hoʻokomo i hāʻule ʻole mai ka wela - ua hāʻule lākou mai ka lihi kūkulu ʻia (BUE) a me ka micro-chipping ma ka ʻoki ʻoki. No ke aha mai? ʻO ka maʻiʻo nickel kiʻekiʻe o Monel 400 (63–70%) a me ke keleawe (28–34%) e hana i kahi puʻupuʻu paʻa, ductile e hoʻopili ai i ka maka rake inā he pāpaʻu loa nā kihi hoʻomaha a ʻoi aku ka ikaika o ka hoʻomākaukau ʻana. ʻO kā mākou hopena: hoʻohana nā kihi rake maikaʻi (12°–15°), radii ihu nui (0.8–1.2 mm), a honi—aole lepo—ooki mau kihi. Ke pale aku nei mākou i ka honi ʻoi; akā, hoʻohana mākou i kahi 0.02-0.04 mm T-land me 0.01 mm chamfer. Hoʻemi kēia i ka haʻihaʻi ʻaoʻao me ka mālama ʻana i ka mana chip. No ka huli ʻana, holo mākou iā Sandvik CoroTurn® 107 me ka papa GC4325. No ka wili ʻana, hāʻawi ʻo Mitsubishi APXM410 me ka uhi VP15TF i ke ola mea paahana he 45 mau minuke ma 85 m/min—me 18 mau minuke me ka hoʻohana ʻana i nā mea hana maʻamau ISO S-grade.
ʻAʻole koho ʻia ʻo Coolant—ʻO kāu laina mua o ka pale
Manaʻo kekahi ua ʻoi aku ka nui o ka mea hoʻoheheʻe kiʻekiʻe no ka mīkini Monel 400. Ua hōʻike ʻē aʻe mākou i ka wā o kahi pūʻulu o nā huila winch center shaft no kahi kaʻa ʻenekinia OEM. Me ka ʻole o ka mea hoʻoluʻu ma ≥70 bar, piʻi aʻe ka ʻino o ka ʻili mai Ra 0.8 µm a i Ra 2.1 µm—a ua ʻike ʻia nā microcracks ma lalo o ka honua ma hope o ka hoʻāʻo ultrasonic. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa o Monel 400 (21.8 W / m · K ma 100 ° C) e paʻa i ka wela ma ka ʻāpana ʻoki. Hoʻomaʻamaʻa kēlā wela i ka mea hana ma ka ʻāina, hoʻolalelale i ka ʻaʻahu diffusion, a hoʻoulu i ka paʻakikī o ka hana ma mua o ka mea hana - e ʻoi aku ka paʻakikī o nā hele ma hope. Ke kauoha nei mākou nā emulsion hiki ke hoʻoheheʻe ʻia i ka ʻaila (8–10% ka hoʻopaʻa ʻana) hāʻawi ʻia ma nā ala kūloko ma 60-90 bar. ʻAʻohe pahū ea. ʻAʻohe noe. ʻAʻole loa i ka aila pololei—ʻaʻole ia i ka lubricity e pono ai e ʻako i ka ʻaila maʻemaʻe. Nānā mākou i ka pH i kēlā me kēia pule a hoʻololi i ka mea hoʻomaha i kēlā me kēia 4 pule, me ka nānā ʻole i ka nui i hoʻohana ʻia. ʻO ka mea hoʻomaʻamaʻa i hoʻohaumia ʻia ke kumu o ka ʻinoʻino wikiwiki ʻana ma luna o nā ʻili i hoʻopau ʻia - ʻoi loa ma kahi kokoke i nā aʻa a me nā ʻoki lalo.
ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻana a me ka hoʻolālā hānai ma mua o ka mana Spindle
Ua ʻoki mākou i nā kino valve 17 i hoʻokahi neʻe - ʻaʻole ma muli o ka hemahema o ka hāmeʻa, akā ma muli o ka haʻalele ʻana. ʻO ka modulus kiʻekiʻe o ka elasticity o Monel 400 (179 GPa) e uhi i ka vibration, akā ua lele kona ikaika hua i 40% ma hope o 5% hana anu. No laila inā ʻae kāu mea paʻa i ka neʻe ʻana o 0.015 mm i ka wā o ka roughing, e loaʻa iā ʻoe nā māka kamaʻilio e kūʻē i ka polishing a hoʻopaʻapaʻa i ka sila ʻana. ʻO kā mākou rula hoʻoponopono: hoʻopili i loko o 1.5 × hapa anawaena o ka ʻāpana ʻoki, e hoʻohana i nā pā kila paʻakikī me nā serration 45°, a e hōʻoia i ka ikaika o ka hoʻopaʻa ʻana me nā cell load-ʻaʻole nā wrenches torque. No nā meaʻai, pale mākou i nā helu hānai mau. Akā, hoʻonui mākou i ka meaʻai e 15% i kēlā me kēia 2 mm o ka hohonu o ka ʻoki ʻana i ka wā o ka roughing. Mālama kēia i ka hoʻouka ʻana i nā spike e hoʻomaka i ka BUE a i ʻole ka huki ʻana i waho. I ka hoʻopau ʻana, hoʻemi mākou i ka hānai ma 30% a hoʻonui iki i ka RPM—ʻoi aku ka maikaʻi o ka hoʻopau ʻana i ka ʻili i 35%, a hāʻule ke koʻikoʻi koena ma lalo o 120 MPa (ana ʻia e XRD).
Mai hoʻokuʻu i ka hoʻomaha hoʻomaha ma hope o ka mīkini - ʻoiai no nā ʻāpana "maʻalahi".
Ua hōʻole ka mea kūʻai aku i nā kumu puna he 42 no ka mea ʻaʻole i hāʻule nā hoʻāʻo leak ma 220 bar — ʻoiai ke hala i nā loiloi nui āpau.

ʻAʻole pili ʻo Monel 400 machining i ka ikaika. E pili ana i ka choreography pololei ma waena o ka mea hana, ka mea hoʻoluʻu, ka hoʻoponopono, a me ka hoʻokele wela. Pili kēlā me kēia ʻāpana. E hoʻololi i kekahi me ka hoʻoponopono ʻole ʻana i nā mea ʻē aʻe, a hāʻule ke ola mea hana - a ʻoi aku ka maikaʻi o ka pono. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mālama mākou i kēlā me kēia hana Monel 400 ma ke ʻano he ʻaelike metallurgical: ʻaʻole ʻoki wale i ka metala, akā mālama i kona ʻano hana palaoa, ka pono o ka ʻili, a me ka pale ʻana i ka corrosion lōʻihi. Inā pili kāu papahana aʻe i ka monel 400 machining—inā paha he hale nozzle cobalt-alloy a i ʻole ka mea hoʻohana ʻole ʻia ʻo T800-e hoʻomaka me ka hōʻoia waiwai, e hōʻoia i kāu kaʻina hana e kūʻē i ka ʻikepili o ka lole honua maoli, a mai manaʻo i ke ʻano o ka alloy e like me 316 stainless.
