Hui Puhi Puka makani

Kū ʻo DONGSHAO ma ke ʻano he mea hana kūikawā ma ka ʻāpana hoʻopaʻa ikehu hou. ʻO ka DONGSHAO Wind Power Bolt Combination ʻaʻole ia he mea paʻa maʻamau; ʻo ia ka hopena palekana-koʻikoʻi i hoʻolālā ʻia no nā koi koʻikoʻi o nā turbine makani uka a me waho.

ʻAʻole like me ka lako lako maʻamau, ua hana ʻia kā mākou hui pū ʻana i ka makani makani no ka pale ʻana i ka haʻalulu nui, nā haʻahaʻa eccentric dynamic, a me nā kūlana lewa ʻino. E like me ka pi'i 'ana o ka makani turbines i ka mana multi-megawatt, lilo ka pono o ka hale kia'i, nacelle, a me ka hookui i ka pahi. Hāʻawi ʻo DONGSHAO i ka hilinaʻi a nā mea hoʻomohala mahiʻai makani a me nā mea hana hale kila. Ke kono nei mākou iā ʻoe e kipa i kā mākou hale hana e kūʻai i ka mea hou loa, kūʻai maikaʻi loa, kūʻai aku, a me ke kiʻekiʻe o ka Wind Power Bolt Combination.

Nā ʻōlelo kikoʻī a me nā ʻāpana

No ka hōʻoia ʻana i ka hoʻokō ʻana me nā kūlana o ka hale kiaʻi makani honua (IEC 61400-6), loaʻa kā mākou Wind Power Bolt Combination ma kahi ākea o nā ana a me nā papa waiwai.

Huahana Huahana: He aha ka Wind Power Bolt Combination?

ʻO ka DONGSHAO Wind Power Bolt Combination maʻamau ka loaʻa ʻana o kahi bolt hex ikaika kiʻekiʻe, kahi nut hex kaumaha, a me ʻelua mea holoi paʻa (flat + taper). Hoʻopili ʻia kēia hui e hoʻopili i nā flanges apo i nā hale kiaʻi kila tubular -5. Ke piʻi aʻe ka kiʻekiʻe o nā turbines (ʻoi aku ma mua o 140m kiʻekiʻe hub), hāʻule ka bolting kuʻuna; hoʻohana ʻia kā mākou Wind Power Bolt Combination i ka hoʻopaʻa ʻana i mua o ka hoʻouka ʻana no ka mālama ʻana i ka ikaika pipili ma lalo o ke koʻikoʻi haʻalulu nui -2.

Nā Pōmaikaʻi ʻenehana nui

Hoʻomaopopo mākou i ka hāʻule ʻole ʻana o ka bolt i ka makani turbine nacelle ʻo ia hoʻi ke kumu kūʻai o ka downtime a me nā uku crane. No laila, ʻo ka Wind Power Bolt Combination ma mua o ka luhi a me ka palekana o ka hale.

1. ʻOi aku ka pale ʻana i ka luhi (anti-loosening)

ʻIke ʻia nā mīkini makani makani i nā miliona o nā pōʻai hoʻoili amplitude. Hoʻolālā ʻia kā mākou Wind Power Bolt Combination me ka hoʻohana ʻana i nā loina o nā mīkini pōʻino hoʻomau e pale aku i ka luhi o ke kaula. Hoʻohana mākou i ka ʻenehana ʻōwili pololei (ma mua o ka ʻoki ʻana) no nā kaula bolt, e hōʻoia ana i ke kahe ʻana o ka palaoa o ka metala ʻaʻole e hoʻopau ʻia, e hoʻonui nui i ka ikaika tensile luhi a hiki i 30%.

2. Ka ʻino a me ka hoʻomalu ʻana i ke kaiapuni

Hōʻike nā mahiʻai ma waho a me nā kahakai i nā mea hoʻopaʻa i nā pae corrosion C5-M. Hāʻawi ʻo DONGSHAO i nā lāʻau lapaʻau kūikawā no ka Wind Power Bolt Combination:

• ʻO ka Zinc Flake Coating: Hāʻawi i kahi pale e kūʻē i nā ion chloride (paʻakai paʻakai) ʻoiai e hāʻawi ana i kahi koena friction hoʻomalu ʻia (µ=0.09-0.16) no ka hoʻopaʻa ʻana i ka torque pono -4.

• HDG (Hot-Dip Galvanized): No nā kahua kahua hale kiaʻi, e hāʻawi ana i ka pale ʻālana i ka makū o ka honua.

• Nānā: Inā loaʻa nā lua ʻino ma luna o ka ʻili o ka bolt, hana ia ma ke ʻano he nucleation point no nā māwae, e hōʻemi nui ana i ke ola luhi. Our coatings prevent this initiation -3-6.

3. Ka mālama ʻana i ka nalo mua ʻana (hoʻokomo ʻia)

Ma nā pilina maʻamau, palahalaha nā micro-imperfections i ka manawa, e hoʻopau ana i ka preloading. Hōʻike ka IEC 61400-6 AMD1 maʻamau i nā koi hou no ka hoʻouka mua ʻana -2. ʻO kā mākou DONGSHAO Wind Power Bolt Combination no kēia me nā hoʻopau ʻili kiʻekiʻe e hōʻemi ana i nā poho hoʻokomo ʻana, e hōʻoiaʻiʻo ana e paʻa mau kāu flange no 20+ mau makahiki.

Noi & Hana

ʻO ka hana nui o ka Wind Power Bolt Combination, ʻo ia ka hāʻawi ʻana i kahi pilina paheʻe a paheʻe.

• Hoʻohui ʻana i ka ʻāpana hale kiaʻi: Hoʻopaʻa pū ʻia nā ʻāpana kila tubular (L-flanges a me T-flanges) -2.

• Nacelle i ka hale kiaʻi: Ka mālama ʻana i nā mana manawa nui i hana ʻia e ka hoʻololi ʻana o ka rotor.

• Lahi i ka Hub (Root Joints): Hoʻokuʻi ʻana i nā lau i hui pū ʻia me ka pahu rotor (nā studs ikaika kiʻekiʻe).

• Nā Hale heleuma o ka Foundation: Hoʻokomo ʻia i loko o nā kahua paʻa no ka hoʻopaʻa ʻana i ka hale kiaʻi holoʻokoʻa (M36 a M64 anawaena) -5-8.

Māhele Huahana 

Hāʻawi mākou i ʻelua mau hoʻonohonoho kumu mua o ka Wind Power Bolt Combination:

1. ʻEleʻele ʻeleʻele kiʻekiʻe kiʻekiʻe ke kumu: Papa 12.9. Hoʻohana ʻia no nā ʻāpana nacelle kūloko e koi ana i ka pololei laka kiʻekiʻe.

2. ʻO ka Extra-Long & Oversized Hex Bolt: Ka anawaena mai 20mm a 42mm (a hiki i 64mm ma ke noi). Hoʻohana ʻia no nā pili flange hale kiaʻi, e hōʻike ana i ka hopena wela wela a ʻeleʻele paha no ka hoʻomalu friction.

No ke aha e koho ai iā DONGSHAO? (ʻIke inoa inoa a me ka hui)

I hoʻokumu ʻia i ka makahiki 1980 a ua hoʻokumu ʻia ma Hebei, ua ulu ʻo Hebei Dongshao Fastener Manufacturing Co., Ltd. mai kahi mea hoʻolako kūloko i kahi ʻoihana hui ʻenehana kiʻekiʻe. ʻAʻole mākou he poʻe kālepa; he mea hana mākou.

ʻO kā mākou mea hana ikaika:

• Mea Hana: 10,000+ sqm o ke kahua hana.

• Lako: Nā mīkini hana nut kiʻekiʻe (Taiwan tech), nā lako poʻomanaʻo anu, nā mea kanu wela (Dongshao Heat Treatment Plant).

Loaʻa honua: Ua hoʻopuka maikaʻi mākou i kā mākou mea hoʻopaʻa i ka Hikina Hema o Asia, ʻEulopa, ʻAmelika ʻĀkau, a me ʻApelika. Ua hoʻohana mua ʻia kā mākou Wind Power Bolt Combination e nā mea kūkulu hale nui, me ka China Railway Seventh Group, CFHI Tianjin Heavy Industry, a me Sinohydro.

Palapala hōʻoia: Ke hana nei mākou ma lalo o nā ʻōnaehana hoʻokele maikaʻi loa, e hōʻoia ana i ka ʻike ʻia o kēlā me kēia pūʻulu o Wind Power Bolt Combination.

Mea Hana Hana & Ho'āʻo

No ka hōʻoiaʻiʻo ʻana i ka hana mechanical o ka Wind Power Bolt Combination, hoʻohana mākou i ka hana ʻana i loko o ka hale:

• Hoʻohuanu: Mekini hoʻoheheʻe nut kiʻekiʻe a me nā mīkini poʻo anu.

• Hoʻomaʻamaʻa Wela: Nā umu hoʻoheheʻe pololei (koʻikoʻi no ka loaʻa ʻana o ka ikaika 10.9/12.9 me ka ʻole o ka hydrogen embrittlement).

• ʻO ka loʻi lola: Mīkini ʻōwili pololei loa.

• Hoʻāʻo: Nā ʻana i nā ʻāpana mākēneki, nā mīkini hoʻāʻo tensile, a me nā mea hōʻike paʻakikī.

FAQ (Nīnau pinepine)

Nīnau: He aha ka ʻokoʻa ma waena o ka bolt maʻamau a me ka Wind Power Bolt Combination? A: Ua hoʻolālā ʻia nā bolts kūkulu maʻamau no nā haʻawe paʻa. Hoʻolālā kūikawā ʻia ka Wind Power Bolt Combination no nā ukana eccentric a me ka luhi kaʻapuni kiʻekiʻe. ʻO ke kaʻina o ka ʻōwili ʻana i ka milo, ka maʻemaʻe o nā mea (ʻaʻole i hoʻokomo ʻia no ka pale ʻana i ka haki ʻana), a me ka coefficient friction hoʻomalu ʻia e hoʻomalu pono ʻia no nā haʻahaʻa ikaika -6.

Nīnau: Pehea wau e hōʻoia ai ua pololei ka preload force i ka wā e hoʻokomo ai? A: No kā mākou 10.9 grade Wind Power Bolt Combination, paipai mākou e hoʻohana i ke ʻano Torque + Angle (Turn-of-Nut). Hāʻawi mākou i nā pepa ʻikepili ʻenehana me nā coefficient friction kikoʻī (µ-total) e hoʻohālikelike i kāu hoʻonohonoho wrench torque hydraulic.

Q: Hiki iā DONGSHAO ke hāʻawi i nā lōʻihi maʻamau a i ʻole nā ​​​​mea kūikawā? A: ʻAe. Kūleʻa mākou i nā hāʻina maʻamau. Inā makemake ʻoe i ka nui ʻokoʻa ma waena o 20mm a me 42cm ke anawaena, a i ʻole e koi i nā mea kikoʻī e like me 42CrMo no ke kū ʻana i ka hopena haʻahaʻa haʻahaʻa (e laʻa, -40°C/ -40°F no nā turbine anuanu), hiki i kā mākou hui loea ke hana i ka Wind Power Bolt Combination e like me kāu kiʻi.

Q: Pehea ʻoe e pale ai i ka luhi corrosion? A: ʻO ka luhi ʻino ka mea pepehi kanaka #1 o nā bolts waho. Hāʻawi kā mākou lapaʻau ʻili (Geomet/Zinc Flake) i kahi pale ʻālana. Manaʻo mākou i nā mea kūʻai aku ma nā wahi haʻahaʻa haʻahaʻa e hoʻohana i kā mākou hui ʻana Wind Power Bolt Combination no ka pale ʻana i ka lua ʻino, ka mea e hōʻemi nui ai i ke kumu hoʻonā kaumaha -9.
