ʻO kekahi ʻike e pili ana i nā piston

ʻO ka Piston kahi neʻe pānaʻi i loko o ke kino cylinder o kahi mīkini kaʻa. Hiki ke hoʻokaʻawale ʻia ke ʻano kumu o ka piston i luna, poʻo a me ke kapa. ʻO ka piko o ka piston ka ʻāpana nui o ke keʻena puhi ahi, a ʻo kona ʻano e pili ana i ke ʻano o ke keʻena puhi i koho ʻia. Hoʻohana nui nā ʻenekini i ka piston flat top, nona ka pono o ka wahi hoʻoheheʻe wela liʻiliʻi. Loaʻa pinepine ʻia nā lua ʻokoʻa ʻo Diesel engine piston top, ʻo kona ʻano kikoʻī, kūlana a me ka nui me ka hoʻokumu ʻana o ka hui ʻana o ka mīkini diesel a me nā koi hoʻopau.

Ma muli o ka hana o ka piston engine combustion ma lalo o ke kiʻekiʻe wela, ke kiʻekiʻe kiʻekiʻe a me nā kūlana haʻahaʻa kiʻekiʻe, ʻoi aku ka kiʻekiʻe o nā koi no ka piston, no laila ke kūkākūkā nui ʻia ka hoʻokaʻawale ʻana o ka piston mīkini hoʻomohala kūloko.
1. E like me ka wahie i hoʻohanaʻia, hiki ke hoʻokaʻawaleʻia i loko o ka piston engine piston, piston engine diesel, piston kinoea maoli.
2. E like me nā mea o ka piston, hiki ke hoʻokaʻawale ʻia i ka piston hao, piston kila, piston alumini alumini a me ka piston hui.
3. E like me ke kaʻina hana o ka hana piston blanks, hiki ke maheleia i ka umekaumaha hoolei piston, extrusion hoolei piston a me forged piston.
4. E like me ke kūlana hana o ka piston, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana: piston non-pressurized a me piston pressurized.
5. E like me ke kumu o ka piston, hiki ke hoʻokaʻawale ʻia i ka piston kaʻa, piston kaʻa, piston kaʻa, piston Marine, piston tank, piston tractor, piston mower lawn, etc.

Me ka ikaika o ka mīkini kaʻa, ka hoʻokele waiwai, ka mālama ʻana i ke kaiapuni a me nā koi hilinaʻi i ʻoi aku ka paʻakikī, ua ulu ka piston i kahi huahana ʻenehana kiʻekiʻe e hoʻohui ana i nā mea hou māmā a me ka ikaika kiʻekiʻe, ka ʻili o ka cylindrical composite kūikawā, nā puka pine kūikawā. a me nā ʻenehana hou ʻē aʻe e hōʻoia i ka pale ʻana i ka wela, ke kūpaʻa ʻaʻahu, ke kuhikuhi pololei a me ka hana hoʻopaʻa maikaʻi o ka piston. E ho'ēmi i ka nalo o ka hana friction o ka mīkini, e hoʻemi i ka hoʻohana wahie, ka walaʻau a me nā hoʻokuʻu. I mea e hoʻokō ai i nā koi hana i luna, ua hoʻolālā ʻia ka pōʻai o waho o ka piston e like me ke ʻano kūikawā o waho pōʻai (convex variable ellipse), ʻo ia hoʻi, ʻo ka ʻāpana kea e kū pono ana i ke axis o ka piston he ellipse a i hoʻoponopono ʻia paha. a hoʻololi ka ellipticity ma ke axis e like me kekahi lula (e like me ka hōʻike ʻana ma ka Figure 1), a ʻo ka pololei o ka ellipticity ʻo 0.005mm; ʻO ka ʻaoʻao waho o ka ʻāpana longitudinal o ka piston he pihi kūpono o ka hana ʻoi aku ka kiʻekiʻe, a ʻo ka pololei o ka contour he 0.005 ~ 0.01mm. I mea e hoʻomaikaʻi ai i ka hiki o ka piston a hoʻonui i ka mana lita o ka mīkini, ua hoʻolālā ʻia nā puka pine o ka piston kiʻekiʻe i loko o ke ʻano micro inner cone a i ʻole ke ʻano curved stress maʻamau (nā puka pine kūikawā), ka pololei o ka nui. ʻO nā puka pine he pae IT4, a ʻo ka pololei o ka contour he 0.003mm. Ma ke ʻano he ʻāpana kī maʻamau o ke kaʻa, loaʻa ka piston i nā hiʻohiʻona ʻenehana ikaika i ka ʻoki ʻana. ʻO ka ʻoihana hana piston home ka mea maʻamau i nā mea mīkini maʻamau a me nā mea hana kūikawā i hui pū ʻia me nā hiʻohiʻona o ka laina mīkini kaʻina piston, no laila, ua lilo nā mea hana kūikawā i mea nui o ka ʻoki ʻoki piston, a ʻo kāna hana a me ka pololei e pili pono i ka. nā hōʻailona maikaʻi o nā hiʻohiʻona nui o ka huahana hope.
