ʻO ka ʻaila pauma he mea hana mīkini maʻamau i hoʻohana ʻia no ka lawe ʻana i nā wai (maʻamau ka wahie wai a i ʻole ka aila lubricating) mai kahi wahi a i kekahi.Loaʻa iā ia kahi ākea o nā noi ma nā ʻano he nui, me ka ʻoihana automotive, aerospace, ʻoihana hana moku a me ka hana ʻoihana, etc.
Hiki ke wehewehe maʻalahi ʻia ke kumu hana o ka paila aila e like me: ka neʻe ʻana o ka wai mai kahi haʻahaʻa haʻahaʻa a hiki i kahi kiʻekiʻe ma o ke kaomi i hana ʻia e ka neʻe mechanical.E hōʻike kikoʻī ana kēia ma lalo nei i nā loina hana o ʻelua mau ʻaila ʻaila maʻamau.
1. Ka loina hana o ka paila pahu:
ʻO ka pauma kaʻa he pauma hoʻoneʻe maikaʻi maʻamau i loaʻa i ʻelua mau pahu meshing me kekahi.Ua kapa ʻia kekahi mea hoʻokele kaʻa a ʻo kekahi i kapa ʻia ʻo ka mea hoʻokele.Ke kaʻa kaʻa kaʻa, kaʻa hoʻokele pū kekahi.Hoʻokomo ka wai i loko o ke keʻena pamu ma o ke āpau ma waena o nā mea hana a hoʻokuʻu ʻia i ka puka i ka wā e huli ai nā pahu.Ma muli o ka meshing o nā kaʻa, ua hoʻopili mālie ʻia ka wai i loko o ke keʻena pamu a hoʻokuʻu ʻia i ka wahi kiʻekiʻe.

2. Ke kumu hana o ka paila piston
ʻO ka paila piston he pamu e hoʻohana ana i ka piston e pānaʻi i loko o ke keʻena pamu e hoʻokuke i ka wai.Aia ia i hoʻokahi a ʻoi aku paha nā pistons, cylinders a me nā kiwi.I ka neʻe ʻana o ka piston i mua, e emi ana ke kaomi i loko o ke keʻena pamu a komo ka wai i loko o ke keʻena pamu ma o ka valve inlet ea.I ka neʻe ʻana o ka piston i hope, pani ʻia ka valve inlet, piʻi ke kaomi, a hoʻokuʻu ʻia ka wai i ka puka.A laila wehe ka puka puka a hoʻokuʻu ʻia ka wai i loko o ka wahi kaomi kiʻekiʻe.Ke hana hou nei i kēia kaʻina hana, e lawe mau ʻia ka wai mai kahi haʻahaʻa haʻahaʻa a hiki i kahi kiʻekiʻe.
Hoʻokumu ʻia nā loina hana o kēia mau ʻaila ʻelua i ka ʻokoʻa o ke kaomi o ka wai e hoʻokō ai i ka lawe wai.Ma o ka neʻe ʻana o nā mea hana mechanical, hoʻopili ʻia a paʻi ʻia ka wai, a laila e hana i kahi kaomi, e ʻae i ka wai e kahe.ʻO ka pauma ʻaila maʻamau he kino pauma, ke keʻena pamu, kahi mea hoʻokele, nā valves a me nā mea ʻē aʻe e ʻike ai i ka lawe ʻana a me ka mālama ʻana i nā wai.
