Hāʻawi ʻo YT27 i ka ʻeli hilinaʻi no nā papahana Tunnel pono hana

I ka wā e pili ana i ka ʻeli ʻana i nā tunnels lawelawe ma lalo o nā alanui o ke kūlanakauhale, ʻaʻole pono kekahi wili.wili pōhaku pneumaticua loaʻa iā ia kona mau kahua hana ma kahi e pono ai ka manawa hana. ʻAʻole e like me nā wili wāwae kahiko e hakakā pinepine nei me nā papa pōhaku ʻaʻole like a i ʻole ka paʻa i ka lepo pulu, ke hoʻomau nei kēia ʻāpana. Ua ʻike mākou i nā limahana e hoʻololi mai ka pneumatic ʻano mine maʻamauwili pōhakus—ʻo kēlā mau hiʻohiʻona maʻamau e wela nui ana i nā hoʻololi lōʻihi a ʻai i nā koʻokoʻo kila—i kaYT27, a ʻike ʻia ka ʻokoʻa ma ka moʻolelo wikiō o kēlā me kēia lā.

No ka hoʻohana pono ʻana i ka YT27, e hoʻomaka ma ka hoʻopili ʻana i kahi laina ea maʻemaʻe ma 0.5–0.7 MPa. ʻAʻohe pono no nā mea aila nani; e hōʻoia wale nō he ʻaila ISO VG32 ka lubricator. ʻO kawiliHolo maikaʻi loa me kahi koʻokoʻo kila hexagon 22mm a me kahi bit 34-42mm no ka hana tunnel. E mālama i ka ikaika hānai paʻa—ʻaʻole kaumaha loa, ʻaʻole māmā loa—a e ʻae i ka piston e hana i ka hana. Hoʻokahi mea a kā mākou poʻe kahua e ʻike koke ai: hana maoli ka muffler hoʻopau. Hiki iā ʻoe ke kū ma kona ʻaoʻao no kahi neʻe piha me ka ʻole o ke kani ʻana o kou mau pepeiao.

Eia ke ʻano ʻokoʻa o ke ao maoli. He mea maʻamauhana ʻeliʻO ka wili wāwae (e like me ka YT24 kahiko a i ʻole nā ​​​​mea like ʻole) e hoʻomaka ikaika akā mae ma hope o ʻelua hola o ka ʻeli ʻana i ka pōhaku one paʻakikī. Hoʻopaʻa ke kila, lilo ka wili i jerky, a hoʻopau ka mea hoʻohana i ka hakakā ʻana i ka mīkini. I loko o kahi tunnel pono, ʻo ia hoʻi ka manawa downtime, wili hou, a me nā luna papahana hoʻonāukiuki. Me ka YT27, noho mālie ka wili ʻana ʻoiai ke paʻi ʻoe i kahi humuhumu lepo a i ʻole kahi aʻa quartz. Hoʻokahe maikaʻi ka hoʻolālā cylinder mua i ka lepo, no laila ʻaʻole ʻoe e kū i kēlā me kēia 30 mau minuke e puhi i ka chuck.

Ua ʻike mākou i kēia no ka mea ke kūkulu nei mākou i kēia mau wili. Ua hana kā mākou hale hana i nā lako wili pōhaku no nā makahiki he ʻumikumamālima—ʻaʻole e hōʻuluʻulu ana mai nā ʻāpana i lawe ʻia mai, akā ʻo ka mīkini ʻana i nā cylinders, nā pistons e mālama ana i ka wela, a me ke kaulike ʻana i nā ʻōnaehana valve i loko o ka hale. ʻAʻole ʻoe e ʻike i kā mākou YT27 ma kahi laina hōʻuluʻulu maʻamau. Loaʻa i kēlā me kēia ʻāpana kahi hoʻāʻo piha ma mua o ka hoʻouna ʻana. ʻO ia ke kumu e hoʻi mau mai ai nā mea hana e hana ana ma nā hoʻonui pono hana ma lalo o ka honua. Pono lākou i kahi wili e hoʻomaka i ke kakahiaka a hoʻomau i ke kuʻi a hiki i ka ʻaina awakea, ua a lā paha, lepo a pulu paha.

No nā papahana tunnel kahi e hōʻike ai ka wili ʻana i ka hala ʻana o ka lā palena, ʻaʻole wale ka YT27 i kahi koho ʻē aʻe. ʻO ia ka ʻokoʻa ma waena o ke kuhi ʻana i kahi e hele ai ka paipu a me ka ʻike e paʻi ʻoe i kāu māka i kēlā me kēia manawa. Inā luhi kāu poʻe hana i ka hakakā ʻana i nā wili lua kahiko, e kelepona mai iā mākou. Loaʻa iā mākou kahi ala maikaʻi e wili ai.
