Hoʻohana nā laina hydraulic kuʻuna i kahi hopena wela hoʻokahi a hana pinepine ʻia i SAE-J525 a i ʻole ASTM-A513-T5, nā mea paʻakikī e hoʻopuka i ka home. Hiki i nā OEM e ʻimi ana i nā mea kūʻai hale ke hoʻololi i nā paipu i hana ʻia i nā kikoʻī SAE-J356A a hoʻopaʻa ʻia me nā sila alo O-ring, e like me ka mea i hōʻike ʻia e Tru-Line.
Ka Luna Hoʻoponopono: ʻO kēia ʻatikala ka mea mua ma kahi moʻolelo ʻelua ʻāpana ma ka mākeke a me ka hana ʻana i nā laina hoʻoili wai no nā noi kiʻekiʻe.
ʻO ka maʻi maʻi maʻi COVID-19 ua hoʻololi i nā loli i manaʻo ʻole ʻia i nā ʻoihana he nui, ʻo ia hoʻi ke kaulahao paipu kila a me ke kaʻina hana paipu.
ʻOi aku ka koʻikoʻi o ka poʻe hana i kēia manawa. He pilikia kanaka kēia maʻi maʻi, a ua hoʻololi ke koʻikoʻi o ke olakino i ke koena o ka hana-ola-pāʻani no ka hapa nui, inā ʻaʻole ʻo nā mea āpau. He pilikia ka hana ʻana a me ka hoʻopaʻa ʻana i nā limahana, me nā mea hana wili paipu akamai.
Ua hoʻololi pū ʻia ka lako kila a me nā kumukūʻai kila maka i ka wā maʻi maʻi.
Ma muli o ka loli ʻana o kēia mau mea ʻelua i ka wā maʻi maʻi, pehea ka pane ʻana o nā hui o ka mākeke paipu?
He mau makahiki i hala aku nei, ua hōʻuluʻulu ka luna o ka hale hana paipu kiʻekiʻe i ke kuleana o kāna ʻoihana i ka ʻoihana: "ʻElua wale nō mea mākou e hana ai ma ʻaneʻi - hana mākou i nā paipu, a kūʻai aku mākou.", ka nui o na mea hoohihia, ka nui o na mea e hoonawaliwali ai i na kumu waiwai o ka hui, a i ole ka pilikia o keia manawa (a i ole keia mau mea a pau, i ka manawa pinepine) he mea waiwai ia no ka hooponopono ana i na luna hoomalu i kaumaha.
He mea nui e hoʻokō a mālama i ka mana ma ka nānā ʻana i nā mea nui: nā mea e pili ana i ka hana ʻana a me ke kūʻai ʻana i nā paipu maikaʻi.
I ka laha ʻana o ka maʻi maʻi, ua hāʻule ka noi paipu ma kekahi mau ʻoihana i ka ʻaneʻane ʻaʻole.
ʻO ka mea pōmaikaʻi, ke hana nei nā kānaka i kā lākou hana. Kūʻai kekahi poʻe i nā pahu hau hou no ka mālama ʻana i ka meaʻai. Hoʻomaka ka mākeke hale ma hope a kūʻai nā kānaka i kekahi a i ʻole nā ​​​​mea hana hou ke kūʻai aku lākou i hale, no laila kākoʻo nā ʻano ʻelua i ke koi no nā paipu liʻiliʻi liʻiliʻi. .
Kiʻi 1. Ua hoʻokumu ʻia ʻo SAE-J525 a me ASTM-A519 ma ke ʻano he pani maʻamau no SAE-J524 a me ASTM-A513T5. ʻO ka ʻokoʻa nui ʻo ia ka SAE-J525 a me ASTM-A513T5 i welded, ʻaʻole maʻemaʻe. 6A (hāʻawi ʻia i loko o ka coil), e hālāwai me nā mea like e koi ai.
Ua loli ka mākeke, akā ua like nā alakaʻi.
E kū mai ana ka nīnau "hana a kūʻai paha" i ka wā e kū ai nā hana hana i nā koina hana kiʻekiʻe a me ka hoʻopaʻa a i ʻole ka emi ʻana o nā kumuwaiwai kūloko.
ʻO ka hana ʻana i nā huahana tubular post-welded pono i nā kumu waiwai nui. Ma muli o ka hoʻopuka a me ka hana ʻana o ka mea kanu, i kekahi manawa he pōmaikaʻi waiwai ke ʻoki i nā ʻāpana ākea i loko o ka hale.
Ma kekahiʻaoʻao, eʻoki ana i 2,000 tons i ka mahina i ka hopena o 5,000 tons o ke kila ma ka waihona, e noho ana i ka nui o ke kālā. ua hoʻopilikia ʻia e ka maʻi maʻi COVID-19 e pili ana i ka loaʻa ʻana o nā limahana akamai, nā kumukūʻai kila, a me ke kahe kālā.
Pela no ka hana paipu ponoi, e pili ana i ke kulana. Hiki i na hui me na kaulahao waiwai nui ke koho i waho o ka hana paipu.
He nui nā ʻoihana e hana ana i nā ʻāpana hydraulic a i ʻole nā ​​​​puʻupuʻu kaʻa e lawelawe ana i nā paipu i kā lākou mau pahu ponoʻī. ʻO ka mea nui, ʻoi aku ka nui o nā EV ma kēia mākeke he liʻiliʻi nā ʻāpana powertrain.
Hoʻokumu pinepine ʻia nā wili pahu pio mai nā hoʻolālā maʻamau. He mea maikaʻi kēia no ka hoʻohana ʻana - hana i nā paipu no kahi noi kikoʻī - akā he mea pōʻino i ke ʻano o ka waiwai o ka pālākiō. e hōʻoia i ka hoʻolālā lua. He kiʻekiʻe loa ka hoʻonohonoho ʻana a me nā koina ʻē aʻe e hōʻoiaʻiʻo ai.
ʻOiaʻiʻo, ʻaʻole e pau ka helu ʻana ma ka ʻoki.ʻAʻole ʻike ʻia kēia kumukūʻai hana e ka mea helu kālā, akā hele mai ia ma ke ʻano o kahi mea hana forklift hou a i ʻole kekahi kanaka ʻē aʻe i ka ʻoihana kaʻa.
Kiʻi 2. Ua aneane like nā hui kemika o SAE-J525 a me SAE-J356A, e kōkua ana i ka mea hope e pani i ka mea mua.
Ua puni nā paipu hydraulic no nā kaukani makahiki. Ua hoʻopaʻa ka poʻe ʻAigupita i ka uwea keleawe ma mua o 4,000 mau makahiki i hala. Ua hoʻohana ʻia nā paipu ʻohe ma Kina i ka wā o ka Xia Dynasty, ma kahi o 2000 BC, a ma hope ua kūkulu ʻia nā ʻōnaehana paipu Roma me nā paipu kepau, kahi huahana o ke kaʻina hoʻoheheʻe kālā.
ʻO nā paipu kila maʻemaʻe ʻole i hana ʻia i ko lākou ʻAmelika ʻĀkau i ka makahiki 1890. Mai ka makahiki 1890 a hiki i kēia lā, ʻo ka mea maka no kēia kaʻina hana he billet pōʻai paʻa. ʻO ka mākeke ʻAmelika ʻAmelika, ua helu ʻia ʻo SAE-J524 e ka Society of Automotive Engineers a me ASTM-A519 e ka American Society for Testing and Materials.
ʻO ka hana ʻana i nā paipu hydraulic maʻemaʻe he hana koʻikoʻi ka hana, ʻoi aku ka nui o nā diameters liʻiliʻi.
I ka makahiki 1970, ua loli ka mākeke. Ma hope o ka noho aliʻi ʻana i ka mākeke paipu kila no kahi kokoke i 100 mau makahiki, ua hoʻokuʻu ʻia ʻo ia e ka paipu welded, i ʻike ʻia he kūpono no nā noi mechanical he nui i ke kūkulu ʻana a me nā mākeke automotive.
ʻElua mau hana hou i kōkua i kēia hoʻololi i ka mākeke. ʻO kekahi o ia mau mea e pili ana i ka hoʻolei ʻana i ka papa, kahi e hiki ai i nā wili kila ke hoʻohua maikaʻi i ka nui o ka palahalaha kiʻekiʻe. 513-T5 ma ka mākeke o ʻAmelika ʻĀkau. No ka huki ʻia ʻana o ka paipu a hoʻopili ʻia, he huahana waiwai.
Mai ka 1990s a hiki i kēia manawa, lawe ʻia mai ka hapa nui o nā paipu laina hydraulic i hoʻopau ʻia ma ka mākeke kūloko, inā i huki ʻia (SAE-J524) a i huki ʻia paha (SAE-J525), i lawe ʻia mai. market.ʻO ke kumukūʻai maikaʻi o nā huahana i lawe ʻia mai he mea paʻakikī.
ʻO ka mākeke o kēia manawa. Ke emi nei ka hoʻohana ʻana o ka huahana maʻemaʻe, huki a hoʻohui ʻia ʻo J524 i nā makahiki. Loaʻa nō ia a loaʻa kahi wahi ma ka mākeke laina hydraulic, akā koho maʻamau nā OEM iā J525 inā hiki ke loaʻa ka huahana welded, huki a hoʻohui ʻia ʻo J525.
Ua paʻi ka maʻi maʻi a ua loli hou ka mākeke. Ke emi nei ka lako o ka honua o ka hana, ke kila a me ka logistic ma kahi o ka wikiwiki e like me ka emi ʻana o ka noi no nā kaʻa i ʻōlelo ʻia aʻe nei. ʻo ia ka SAE-J356A, e hoʻokō ana i nā koi o nā noi hydraulic he nui (e nānā i ke kiʻi 1).
He pōkole a maʻalahi nā kikoʻī i paʻi ʻia e ka SAE, no ka mea e wehewehe ana kēlā me kēia kikoʻī i hoʻokahi wale nō kaʻina hana no ka hana ʻana i ka paipu. laina hydraulic anawaena.
Kiʻi 3. ʻOiai ua manaʻo ka poʻe he ʻoi aku ka maikaʻi o nā paipu welded a me ke anu i ʻoi aku ka maikaʻi ma mua o nā paipu hoʻonohonoho welded a me ke anu, ua hoʻohālikelike ʻia nā waiwai mechanical o nā huahana ʻelua.
Manaʻo kekahi poʻe ʻenekinia ʻoi aku ka maikaʻi o ka J525 i nā noi hydraulic kaomi kiʻekiʻe, e like me nā mea i hoʻohana ʻia i nā mea kaumaha. ʻAʻole i ʻike nui ʻia ʻo J356A, akā ʻo ia hoʻi kahi wai kahe kiʻekiʻe e lawe ana i nā kikoʻī.
Loaʻa i nā mea waiwai nā waiwai like (e nānā i ke kiʻi 2). ʻO nā ʻokoʻa liʻiliʻi o ka hui kemika e pili ana i nā ʻano mechanical i makemake ʻia.
Hoʻokaʻawale nā ​​ʻano tubing i kahi hoʻonohonoho maʻamau o nā ʻāpana hana mechanical like, e hoʻololi iā lākou i nā noi he nui (e ʻike i ke kiʻi 3). ʻO ia hoʻi, inā ʻaʻole loaʻa kekahi, hiki i kekahi ke hoʻokō i nā koi. ʻAʻohe mea e pono e hana hou i ka huila;ua loaʻa i ka ʻoihana kahi huila ikaika a kaulike i kona hiki.
Ua lilo ʻo Tube & Pipe Journal i ka makasina mua i hoʻolaʻa ʻia no ka lawelawe ʻana i ka ʻoihana paipu metala ma 1990. I kēia lā, ʻo ia wale nō ka paʻi ma ʻAmelika ʻĀkau i hoʻolaʻa ʻia i ka ʻoihana a ua lilo i kumu hilinaʻi nui o ka ʻike no nā ʻoihana paipu.
I kēia manawa me ke komo piha ʻana i ka paʻi kikohoʻe o The FABRICATOR, hiki ke maʻalahi i nā kumuwaiwai waiwai waiwai.
Loaʻa ka paʻi kikohoʻe o The Tube & Pipe Journal i kēia manawa, e hāʻawi maʻalahi ana i nā kumuwaiwai waiwai waiwai.
E hauʻoli i ke komo piha i ka paʻi kikohoʻe o STAMPING Journal, e hāʻawi ana i nā holomua ʻenehana hou, nā hana maikaʻi loa a me nā nūhou ʻoihana no ka mākeke stamping metal.
I kēia manawa me ke komo piha ʻana i ka paʻi kikohoʻe o The Fabricator en Español, hiki ke maʻalahi i nā kumuwaiwai waiwai waiwai.
