Pehea i hoʻolālā ʻia a hoʻohana ʻia ai nā puna wai lōʻihi?

Pono ʻoe i ka ikaika huki ma kahi lōʻihi, akā pōkole loa nā punawai maʻamau. ʻAʻole palekana ka hoʻohui ʻana iā lākou, a me ka hoʻohana ʻana i ka ʻāpana hewa hiki ke hoʻopau i kāu ʻōnaehana holoʻokoʻa.

ʻO ka pūnāwai hoʻolōʻihi lōʻihi he pūnāwai i hana ʻia me ka ratio kiʻekiʻe o ka lōʻihi-a-diameter, i hoʻolālā ʻia no nā noi e pono ai ka ʻāʻī ma kahi mamao. Pono lākou i ka nānā kūikawā i ke kūpaʻa waiwai, ka hoʻopaʻapaʻa mua ʻana, a me ke alakaʻi no ka pale ʻana i ke kuʻekuʻe ʻana i ka wā o ka hana.

I kaʻu hana, I've seen that you cannot simply "stretch" he hoʻolālā puna maʻamau e hoʻolōʻihi ai. As soon as a spring's body length becomes many times its diameter, hoololi loa kona ano. Hoʻomaka ia e hana liʻiliʻi e like me ka pūnāwai paʻa a ʻoi aku e like me ke kaula metala. Hoʻopuka kēia hoʻololi i kahi hoʻonohonoho hou o nā pilikia ʻenekinia e pono e hoʻoholo i ka palekana o ka puna, hilinaʻi, a hoʻokō pono i kāna hana ma kāna huakaʻi holoʻokoʻa.

He aha ka mea e kūpono ai i kahi punawai hoʻonui e like me "Long"?

ʻO ka huaʻōlelo "long" me he mea lā ke nānā aku i nā pūnāwai. How do you know if you need a standard spring or if you've crossed the line into a "long spring" hoʻolālā?

Manaʻo ʻia kahi pūnāwai "lōʻihi" ke ʻoi aku ka lōʻihi o kona kino ma mua o ʻumi manawa o kona anawaena waho (a 10:1 ratio). ʻO kēia ratio kiʻekiʻe ke kumu nui e hoʻolauna i nā pilikia hoʻolālā kūikawā, e like me ka ʻoi aʻe o ka pilikia o ka wili, haʻalulu, a me ka distortion ma lalo o ka ukana.

Hoʻohana pinepine au i kēia 10:1 ratio ma ke ʻano he hoʻomaka ke kūkākūkā ʻana i kahi papahana hou me kahi ʻenekinia. Ma lalo o kēlā ratio, Hoʻohana pinepine ʻia nā loina hoʻolālā punawai maʻamau me ka pilikia ʻole. Akā ke hele mākou ma mua o ia, pono mākou e hoʻomaka i ka noʻonoʻo ʻokoʻa. HE LOG, slender spring body can easily get caught on nearby components or even tangle with itself if it's not properly guided. Pono mākou e noʻonoʻo i nā vibrations harmonic. E like me ke kaula guitar, hiki i ka punawai lōʻihi ke haʻalulu i kekahi mau alapine, hiki ke kumu i ka luhi a me ka hemahema. These are problems you just don't see in shorter, nā pūnāwai paʻa.

ʻOi aku ma mua o ka lōʻihi wale nō

ʻO ka ratio lōʻihi-a-diameter ka mea koʻikoʻi e kuhikuhi i ke ala ʻenekinia.

• 'Ōlelo 10:1 Kuhikuhi: While not a rigid rule, ʻO kēia lākiō he hōʻailona kūpono i hoʻokumuʻia i kaʻoihana puna. Hōʻike ia i ka manawa e lilo ai ka hiki ʻole i ka manaʻo nui.
• Paʻa a me ke alakaʻi: ʻAʻole hiki i kahi pūnāwai lōʻihi ke kākoʻo i kona kaumaha ponoʻī me ka ʻole o ka luʻu ʻana a i ʻole ke kulou ʻana, ʻoi aku ka hoʻokomo ʻia ʻana ma ke alo. Pono paha ia i kahi koʻokoʻo alakaʻi e holo ana ma waena o kona kikowaena a i ʻole kahi alahele e hele ai i loko e pale ai i ka paʻi ʻana ma nā wahi ʻē aʻe o ka hui..
• ʻO ka haʻalulu a me ka Harmonics: ʻO ka lōʻihi o ka puna, ʻo ka haʻahaʻa o kona alapine maoli. I nā mīkini e hana ana i ka wikiwiki kiʻekiʻe, hiki i kēia ke alakaʻi i ka resonance, kahi e haʻalulu ʻole ai ka pūnāwai, alakaʻi i ka ʻaʻahu wikiwiki a me ka hemahema.

No ke aha e paʻakikī ai ka hana ʻana i nā punawai lōʻihi?

You'd think making a long spring is easy—just let the coiling machine run for longer. Akā i ka ʻoiaʻiʻo, ʻO ka mālama ʻana i ka maikaʻi ma luna o kēlā lōʻihi he pilikia koʻikoʻi.

He mea paʻakikī ka hana ʻana i nā pūnāwai hoʻonui lōʻihi no ka mea paʻakikī loa ka mālama ʻana i ka pitch kūlike a me ka haʻalulu mua i ka lōʻihi holoʻokoʻa.. Hoʻonui ʻia nā ʻokoʻa liʻiliʻi o ka uea a i ʻole ka wikiwiki o ka mīkini, ke alakaʻi nei i ka hana like ʻole a me nā wahi nāwaliwali i ka pūnāwai.

Ma kā mākou mau mīkini coiling CNC, every part of the process is computer-controlled, from the wire feed rate to the coiling point. No kahi puna pōkole, the process is over in a second. For a spring that's several feet long, pono ka mīkini e hoʻomau i ke kūlike kūpono no ka manawa lōʻihi. Pono e mau ke ku'eku'e ma ka uwea i kona hanai ana mai ka spool. Ina e luu no kekahi manawa, e emi iho ana ka ha'alulu mua ma ia mahele o ka puna. Ina mahuahua, e paa loa na wili. Hiki ke hoʻonui i kēia mau hewa liʻiliʻi, creating a spring that doesn't pull with a uniform force. Ma hope o ka wili ʻana, He paʻakikī hoʻi ka lawelawe ʻana i kēia mau pūnāwai. Hiki iā lākou ke ʻōniʻoniʻo a wili ʻia paha ma mua o ka hiki ʻana i ka umu wela.

ʻO ka Luʻi o ka Kūlike

ʻO ka pololei ke kī, and it's much harder to maintain over a greater distance.

• Ka Mana Hoohuoi mua: ʻO kēia ka ikaika e hoʻopaʻa i nā wili. Ma kahi punawai lōʻihi, pono mākou e hōʻoia i kēia ikaika mai ka hui mua a hiki i ka hope. Pono kēia i nā hoʻonohonoho mīkini paʻa a me ka maikaʻi o ka uea paʻa. ʻAʻole e hāʻawi ka pūnāwai i kahi maʻalahi, huki laina.
• Kaulike Pitch: ʻO ka hakahaka ma waena o nā'ōwili (pitch) pono e pololei. I kahi punawai lōʻihi, Hiki i nā ʻokoʻa wela o ka uea a i ʻole ka mīkini ke hoʻoheheʻe i ka pitch, pili ana i ka helu puna.
• Ka lawelawe ʻana a me ka mālama ʻana i ka wela: HE LOG, palupalu ka puna maka. Pono e lawe akahele ia i na umu hooluolu. Inā kūlou a kikoo paha ma mua o ka mālama ʻana i ka wela, e hoʻokomo mau ʻia ka hemahema i loko o ka mea, e hoopoino ana i ka hapa.

Where Are These Extra-Long Springs Actually Used?

You understand the design challenges, but where would you actually find a spring that's several feet long? ʻOi aku ka maʻamau o kā lākou mau noi ma mua o kou manaʻo.

ʻO nā pūnāwai hoʻolōʻihi lōʻihi nā mea koʻikoʻi i nā ʻōnaehana counterbalance nui. You will find them on large overhead doors, nā poʻi ʻoihana kaumaha, mīkini mahiʻai[^1] e like me nā lāʻau lapaʻau, a ma nā ʻōnaehana rigging keaka e hāpai a hoʻoneʻe maʻalahi i nā mea o ke kahua koʻikoʻi.

Ua hana hou au ma kahi papahana no kahi hui e kūkulu nei i nā mea puhi paka nui no nā hale ʻaina. The lid was extremely heavy, a ua makemake lākou i ala e wehe ai ke kuke me ka lima hoʻokahi. Ua hoʻolālā mākou i ʻelua pūnāwai hoʻonui lōʻihi e holo ana ma hope o ka ʻāpana. The springs provided a constant pulling force that perfectly counterbalanced the lid's weight, e manao ana he mea kaumaha ole. He noi maʻamau kēia no ka punawai hoʻonui lōʻihi: ka hāʻawi ʻana i kahi ikaika kikoʻī ma kahi huakaʻi lōʻihi e maʻalahi ai ka neʻe ʻana o kahi mea kaumaha. ʻIke ʻoe iā lākou i hoʻohana ʻia e like me nā pūnāwai hoʻihoʻi ma nā mīkini ʻenehana nui a me nā mea hoʻopaʻapaʻa ma nā ʻōnaehana conveyor e lōʻihi lōʻihi..

Nā noi e makemake ana i kahi lōʻihi

Hoʻoponopono kēia mau pūnāwai i nā pilikia kahi e pono ai ka ikaika ma kahi mamao.

• Pūnaehana Kūlike: ʻO kā lākou hoʻohana mua e hoʻopau i ke kaumaha kaumaha. Aia kēia me nā puka ʻoihana nui, nā ala hele ma luna o nā kaʻa kaʻa, kiaʻi mīkini hana kaumaha, a me ka wehe ʻana i nā puka makani a i ʻole nā ​​hatches. The spring's stored energy does most of the lifting work.
• Nā mea hana hoʻopaʻapaʻa: I nā ʻōnaehana e like me nā kāʻei conveyor lōʻihi a i ʻole nā ​​​​mea mahiʻai, hoʻohana ʻia nā pūnāwai hoʻonui lōʻihi no ka mālama ʻana i ka haʻalulu mau, hoʻopaʻapaʻa a mālama i nā kāʻei a i ʻole nā ​​kaulahao e holo mālie.
• Mechanisms Hoʻihoʻi: Hoʻohana ʻia lākou ma nā loulou mechanical nui a me nā robotics ʻoihana e hoʻihoʻi i nā ʻāpana i ko lākou kūlana hoʻomaka ma hope o kahi neʻe lōʻihi..

Hopena

ʻO nā pūnāwai hoʻolōʻihi lōʻihi nā ʻāpana kūikawā i wehewehe ʻia e kahi ratio kiʻekiʻe o ka lōʻihi-a-diameter. Hoʻohana ʻia lākou i nā ʻōnaehana counterbalance a me nā tensioning e pono ai ka ikaika ma kahi lōʻihi.

[^1]: E ʻike i ke kuleana koʻikoʻi o nā pūnāwai hoʻonui lōʻihi i ka hoʻomaikaʻi ʻana i ka pono o nā lako mahiʻai.
