Ke hōʻike nei nā ʻenekinia a hale hana noho valve, ʻAʻole lākou e kauoha wale ana i kahi ʻāpana - ke hoʻopaʻa nei lākou i ke kūpaʻa dimensional ma lalo o 350 bar, hoʻopaʻa i ke kūpaʻa ma hope o 10,000 cycles, a me ke kūpaʻa metallurgical ma waena o 500 mau ʻāpana. Ua ʻike mākou i ka nui o nā papahana i hoʻopaʻa ʻia no ka mea ua hele ka noho i ka wā kaʻa wela, a i ʻole ka micro-porosity i hoʻoulu i ka leaka mua ʻana i nā manifold hydraulic. ʻO ia ke kumu ʻaʻole ʻo ka pololei he koi kūʻai aku - ʻo ia ka palena haʻahaʻa e koi ai.
No ke aha ʻo "Valve Seat Factory" kahi huaʻōlelo ʻimi hoʻopunipuni—a ʻo kāu mea e pono ai
ʻO ka hapa nui o nā mea kūʻai aku e hoʻokomo i ka "valve seat factory" i Google e manaʻo nei e hana turnkey. Akā i ka hoʻomaʻamaʻa ʻana, pili ka kūleʻa i ʻekolu mau mea hiki ʻole ke kūʻai aku: ka haku waiwai, geometric fidelity, a me ka traceability. Pono ka hoa ʻoiaʻiʻo e lawelawe i ka AMS 5387 cobalt alloy—ʻaʻole wale i ka mīkini, akā hoʻolei ʻia me ka hoʻokele dendritic spacing, a laila hoʻopau i ka ili hoʻopaʻa i ± 0.005 mm TIR oiai e mālama ana i ke koʻikoʻi koena. Ua hāʻawi mākou ma luna o 12,000 mau noho valve no nā paila piston kiʻekiʻe mai ka makahiki 2019. Ke lawe nei kēlā me kēia pūʻulu i ka hiki ke ʻike i ka nui o ka wela, nā hōʻike CMM no nā anawaena koʻikoʻi, a me ka hōʻoia ʻana i ka ʻeleʻele ma Ra ≤ 0.4 µm ma nā maka sila.
ʻEhā mau ʻike loea ʻaʻole e hōʻike ka hapa nui o nā mea hoʻolako
ʻO ka mea mua, koi ʻia nā alloys cobalt-nickel i nā kahe hana hoʻoheheʻe ʻia. Pono pinepine nā noho i hoʻolei ʻia i ke one he 40% ka wehe ʻana i ka waiwai—nui loa no nā ala hana maʻamau. Hoʻohana mākou i nā mea hoʻokomo carbide maʻamau me nā uhi PVD TiAlN a me nā helu hānai adaptive e hāʻule ana mai 120 mm/min a i 35 mm/min i ka wā e hele ai i ka wahi i hoʻopilikia ʻia i ka wela kokoke i ka alo noho.
ʻO ka lua, pili pono ka wehewehe ʻana o GD&T i ka hana. ʻO kahi noho i kuhikuhi ʻia me Ø0.015 mm kūlana hoʻomanawanui pili i ka pahu hoʻokele? Pono ia i ka alignment optical in-process—ʻaʻole i ka nānā ʻana ma hope o ka pau ʻana. Hōʻoia mākou i nā pilina datum ma mua o ka mālama wela hope, ʻaʻole ma hope.
ʻO ke kolu, ʻoi aku ka maikaʻi o ka ʻili i ka ʻawaʻawa wale nō. Ana mākou i nā ʻanuʻu paʻakikī liʻiliʻi ma waena o ke alo o ka noho (HV300–HV420) a hana i ka hoʻāʻo ʻana o ka fluorescent penetrant ma nā ʻāpana āpau—ʻaʻole nā mea laʻana wale nō—e hopu i nā mea ʻole o lalo o ka honua i ʻike ʻole ʻia e CMM.
ʻO ka hā, he mea ʻole ka hōʻoia ʻana i nā mea me ka ʻole o ka hui pū ʻana o ka mea hoʻolako. Hoʻomohala pū mākou i nā kikoʻī billet maka me kā mākou mea hoʻolako cobalt alloy ma Kelemania, e kauoha ana i ka hōʻike ʻana i ka nui o ka palaoa ASTM E112 a me ka hōʻoia ʻana i ke kūʻē ʻana o ka corrosion intergranular no ASTM G28A.
He aha ka mea e hoʻokaʻawale ai i kahi mea hana no ka noho kiwi pololei
ʻAʻole ia e pili ana i ka loaʻa ʻana o nā mīkini CNC. E pili ana i ka mālama ʻana i nā mea e hana nei ma waena o lākou:
- Ka mana hoolei: Ka hoʻolele kālā no nā geometries paʻakikī (e laʻa.
- Ka hoʻopaʻi ʻana i ka mīkini: ʻO ka hoʻopau ʻana i nā ʻāpana conical sealing multi-axis me ka hoʻohana ʻana i nā papa rotary me ka ± 1 arc-second repeatability, ʻaʻole wale 3-axis milling.
- Hoʻohui hoʻomaʻamaʻa wela: Hoʻokuʻu i ka pilikia ma 950°C me ka hoʻopiha ʻana i ka argon, a ukali ʻia e ka hoʻoluʻu ʻana ma 15°C/hola e pale ai i ka hoʻokumu ʻana o ka sigma i loko o nā ʻāpana kobalt.
- Hoʻopau hōʻoia: ʻO ka palapala ʻāina topography ma o ka interferometry kukui keʻokeʻo-ʻaʻole i ka hala ʻana o ka profileometer wale nō-e hōʻoia i ka ratio o ka bearing area (Abbott curve) e hoʻokō i nā koi sila hydraulic.
Ke hōʻole nei mākou i ka 6.2% o nā bilets kobalt alloy e hiki mai ana ma muli o ka hoʻāʻo ultrasonic wale nō. ʻAʻole ia he mea ʻino - ke pale nei i nā hemahema o ke kahua.
Ke koho ʻana i kāu hoa noho ʻo Valve: ʻEkolu mau hōʻoia hiki ke hana
Ma mua o kou kau inoa ʻana i kahi NDA, e noi i kēia mau mea—a laila e hōʻoia:
- E noi i nā hōʻike CMM ʻekolu hope loa no kahi geometry noho like. E hoʻohālikelike maoli me ka inoa ma ka maka sila, ke anawaena hoʻokele, a me ka perpendicularity hope. Inā kaʻana like lākou i ka ʻikepili hōʻuluʻulu, e haʻalele.
- E noi i kā lākou hōʻike hōʻike hōʻike waiwai (MTR).. ʻO ke ʻano o ka traceability ʻoiaʻiʻo e pili ana kēlā me kēia puʻu wela i ka loiloi kemika, nā hopena tensile, a me nā kiʻi microstructure-ʻaʻole i kahi helu palapala.
- E nānā i kā lākou ʻōlelo hiki iā GD&T. Ke hōʻoiaʻiʻo nei lākou i ka hoʻomanawanui kūlana composite? Hiki iā lākou ke paʻa i ka ʻaoʻao o kahi ʻili i loko o 0.008 mm ma waena o kahi arc 120°? Inā pili kā lākou pane "e ho'āʻo mākou," ʻaʻole lākou i hana ma mua.
QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD. ke hana nei kēia ala i kēlā me kēia lā-ʻaʻole ma ke ʻano he ʻokoʻa, akā ma ke ʻano he kaʻina hana maʻamau. ʻO kā lākou ʻoihana ISO-compliant ma Qingdao e mālama i nā mea a pau mai ka AMS 5387 cobalt alloy nozzles a i nā kumu paʻa kila kila, me nā palapala piha mai ka loaʻa ʻana o nā mea waiwai ma o ka hoʻāʻo ʻana i ke kaomi hana hope.
Manaʻo Hope: Ana ʻia ka pololei ma ka ʻalo ʻana i ka hiki ʻole
ʻAʻole kūʻai ʻia kahi noho valve e kahe ana ma 200 bar i $87 i ka ʻōpala. He $12,000 ke kumu kūʻai i ka wā hoʻomaha no kahi wili ʻana i waho. He $220,000 ke kumu kūʻai no nā ʻauwaʻa kaʻa ʻenekinia. E uku ana i ka inoa—ke hoʻopiʻi ka mea hoʻohana hope o kāu mea kūʻai aku i kāu hōʻailona no ka hemahema.
ʻO ka pono hale hana noho valve hoʻopau i kēlā mau hoʻololi ma mua o ka lele ʻana o ka chip mua. ʻAʻole lākou e hālāwai wale i nā kikoʻī - ke manaʻo nei lākou pehea e pili ai ka hoʻonui ʻana i ka wela, ka hāmare wai, a me ka hoʻouka ʻana me kā lākou geometry a me ka microstructure. ʻAʻole kēlā hana. ʻO ia ka hoʻoili pilikia-hana pololei.
