Ke hāʻule ka pauma hydraulic ma lalo o ke kaomi 350-bar, ʻaʻole pinepine ka mea hewa i ka hale a i ʻole ke sila-ʻo ia ka Pākuʻi Stellite. ʻAʻole wale kekahi plug. Hoʻokahi me ka 0.005 mm concentricity pololei, AMS 5387-compliant cobalt matrix, a ʻaʻohe micro-cracks ma hope o ka mālama ʻana i ka wela. ʻO ia ke kumu ʻaʻole ʻimi nā ʻenekinia ma Houston, Hamburg, a me Singapore i nā "pulu kobalt alloy." Huli lākou i a hale hana hoʻoheheʻe stellite ka moku moku—aole olelo hoopomaikai.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua hoʻolako i kēlā mau ʻāpana mai ka makahiki 2012. ʻAʻole mai kahi papa inoa. Mai ka nānā ʻana i ka hemahema o ka honua maoli: nā nozzles māwae i loko o nā paila hoʻoheheʻe waho, e ʻai ana i nā huila winch center shaft ma nā kaʻa ʻenekinia Arctic-grade, ʻaʻahu mua i nā hale pahu pahu piston pump kiʻekiʻe. Ua ʻike mākou i kēlā me kēia ʻano hemahema - no laila e mīkini mākou i kēlā me kēia plug Stellite e hoʻopau iā lākou ma mua o ka hoʻomaka ʻana.
Eia ka mea e hoʻokaʻawale ai i kahi plug hana mai kahi e lōʻihi 3x ka lōʻihi i ka lawelawe: ka mana metallurgical, ʻaʻole wale ka pololei machining. ʻAʻole "paʻakikī i ka mīkini" ko Cobalt-based T800 a me AMS 5387 - ʻaʻole lākou e kala ʻia inā kuhi hewa ʻoe i ka hoʻonui ʻana i ka wela i ka wā e hoʻohuli ai a hoʻokuʻu paha i ka hoʻoheheʻe ʻana ma mua o ka wili ʻana. Ma kā mākou hale hōʻoia ISO ma Qingdao, hoʻomaka kēlā me kēia plug Stellite me ka traceable, i hōʻoia ʻia i ka waiwai maka—ʻaʻole i ʻae ʻia nā palapala wili me ka ʻole o ka hōʻoia kikoʻī. Holo mākou i nā mea e komo mai ana ma o ka loiloi OES, a laila hāʻawi i kēlā me kēia wahi wela i kahi ID kūʻokoʻa i hoʻopaʻa ʻia i kā mākou ʻōnaehana ERP. Inā hōʻike ka mea kūʻai i kahi anomaly ma Lot #QS-24-8817, huki mākou i nā moʻolelo kaʻina holoʻokoʻa: ka hoʻolei ʻana i ka palaoa, CNC toolpath logs, CMM scan data ma 32 inspection point, surface roughness (Ra ≤ 0.4 µm), and post-heat-treatment hardness (42–48 HRC, i hōʻoia ʻia ma ʻekolu wahi). ʻAʻohe kuhi. ʻAʻohe pūʻulu awelika.
Hoʻopaʻapaʻa paha kekahi he ʻoi aku ka maʻalahi o nā mea Stellite ma waho o ka papa. Akā ʻaʻole helu ʻia ke kumukūʻai ma ke kauoha kūʻai - ua ana ʻia i ka wā hoʻomaha. ʻO kahi plug $210 i hāʻule ma hope o 4,200 mau kaʻina e ʻoi aku ka nui ma mua o kahi plug $390 i helu ʻia no nā pōʻai 14,500 i ka wā e nalowale ai kāu rig waho i nā hola 18 o ka manawa injection. ʻOi aku ka ʻino: hoʻololi pinepine nā mea hoʻolako maʻamau iā Stellite 6 me nā huila cobalt-nickel ʻoi aku ka liʻiliʻi me ka nele o ka dispersion chromium carbide e pono ai no nā kaiapuni slurry erosive. ʻAʻole mākou e pani. Hoʻāʻo mākou. Loaʻa kēlā me kēia plug i ka hoʻāʻo paʻakai (ASTM B117, 500 mau hola), hydraulic proof pressure (1.5x kaomi hana, paʻa no 10 mau minuke), a me ka nānā ʻana i ka ultrasonic no ka ASTM E114. Inā ʻaʻole i hala nā ʻekolu, ʻoki ʻia - ʻaʻole hana hou.
Hoʻoholo pū mākou i nā mea a ka hapa nui o nā hale hana e ʻae ʻole: nā palena geometry. Hoʻohana ʻia nā plug Stellite maʻamau i nā ʻano cylindrical maʻalahi. Ke koi nei nā noi maoli i nā lua eccentric, nā poʻohiwi hoʻopaʻa asymmetric, a i ʻole nā awāwa hoʻohuihui i hoʻohui ʻia i loko o ka hoʻonohonoho like. ʻO kā mākou mau kikowaena wili 5-axis e mālama i nā hiʻohiʻona e koi ana i ʻekolu hoʻonohonoho ma kahi ʻē aʻe-e hōʻemi ana i ka hewa kumulative a hoʻopau i ka distortion hoʻoponopono hou. No hoʻokahi pāpaʻi ʻEulopa OEM, ua hoʻolālā hou mākou i kahi plug Stellite lua-orifice me nā ala kahe offset a me ka mānoanoa pā 0.012 mm ma waena o nā awa. Ua ʻōlelo ka mea hoʻolako kumu i nā pule he 14 a hōʻole i ke kuleana no ka haki ʻana i ka luhi. Hāʻawi mākou i loko o 6 mau pule—me ka hōʻoia ʻana i ka kānana kānana e hōʻike ana i ka 22% haʻahaʻa haʻahaʻa haʻahaʻa ma ka hui. Pehea? No ka mea, loaʻa i kā mākou hui nā mea ʻenekinia hoʻolālā pahū mua i hoʻohuli i nā hemahema ma ka pūnaewele-ʻaʻole heluhelu wale i nā kelepona GD&T.
A hale hana hoʻoheheʻe stellite ʻaʻole i wehewehe ʻia e kāna mau kapuahi a me nā wili. Ua wehewehe ʻia e ka pane ʻana i nā nīnau ʻekolu: He aha ka hopena i ka wā e wela ai ka mea i ka wā wili hope? Aia ma hea ka palena ʻai nāwaliwali loa e pili ana i ka maka sila? A-ʻo ka mea nui loa-he aha ka mea hoʻohana hope e ana maoli ai i ke kula? E pane mākou i nā mea ʻekolu ma mua o ka ʻoki ʻana i ka chip mua. ʻO ia ke kumu e komo ai kā mākou mau pahu i loko o nā pahu hoʻomalu i lalo o ka moana i helu ʻia i ka 10,000 psi, nā ʻōnaehana hoʻoheheʻe wahie kiʻekiʻe i nā kaʻa haul mining, a me nā ʻōpala hoʻoheheʻe pololei e lawelawe ana i nā slurries polymer abrasive. ʻAʻole no ko lākou hālāwai ʻana i nā kikoʻī - akā no ka mea ola lākou i nā kūlana ʻaʻole uhi nā specs.
Ke nānā nei mākou i mua, ke hoʻonui nei mākou i kā mākou hiki i nā kaʻina hana hoʻoheheʻe ʻana-machining no nā hui Stellite nui loa-e like me nā kino valve monolithic me nā noho plug i hoʻohui ʻia i hoʻokahi ninini, a laila hoʻopau ʻia i hoʻokahi hoʻonohonoho NC. Ke hoʻomaka nei ka hana hōʻoia no ka hoʻokō API 6A a me NORSOK M-650. Akā ʻaʻole i hoʻololi ʻia ke kumu: ʻaʻohe ʻāpana e haʻalele iā Qingdao ke ʻole ia e hele i ka hoʻāʻo hana like me ka hui hope. Inā koi kāu noi i ka ʻae ʻole e pili ana i ka pale ʻana i ka erosion, ke kūpaʻa dimensional, a i ʻole ke kūlike metala—e hoʻomaka ana kāu plug Stellite aʻe ma aneʻi.
