ʻO ka naʻauao kaʻaahi: pehea e hōʻoia ai ʻaʻole e hāʻule ka diesel ma ka liʻiliʻi o 50
ʻAʻole pili ka hapalua o ka lōʻihi o nā kaʻaahi Lūkini i ka hoʻohana ʻana i nā kaʻa uila. Ke huki ʻia nei ko mākou mau kaʻa e ka locomotive diesel - he locomotive, ʻo ia ka mea pani pololei o ka locomotive mahu, a ua lako me kahi ʻenekini diesel like i kau ʻia ma luna o nā kaʻa. He mau mea hou aku. Pehea e hakakā ai nā limahana ʻo Russian Railway i ka hau, a he aha ka nui o ka pākaukau e hoʻomaka ai i kahi kaʻaahi?
He wā paʻakikī ka hoʻoilo ʻaʻole wale no nā kaʻa a me nā mea nona lākou. ʻAʻole naʻe nā ala nui o ka ʻāina nui, akā he alahao. Kanawalukūmālima tausani kilomita, kahi e holo ai nā haneli o nā kaʻa ukana a me nā kaʻa kaʻa i kēlā me kēia lā. ʻOi aku ma mua o ka hapalua o kēia ala ʻaʻole i electrified: lawelawe nā locomotives diesel ma ia mau ala, kahi i loaʻa pinepine ʻia ma nā wahi me ka paʻakikī a me nā kūlana climatic. I nā huaʻōlelo ʻē aʻe, ka hoʻokele diesel.
ʻO nā pilikia o nā kaʻa kaʻaahi e holo ana ma ka wahie "kaumaha" e like me nā mea kaʻa maʻamau: ka wahie diesel a me ka aila mānoanoa i ke anuanu, hoʻopili ʻia nā kānana me ka paraffin. Ma ke ala, loaʻa i nā kaʻa kaʻa kaʻina hana no ka hoʻololi ʻana i ka momona mai ke kauwela a i ka hoʻoilo: nā kaʻa traction, nā bearings, nā pahu pahu a me nā mea hou aʻe e mālama i ka mālama wā. Hoʻokaʻawale i nā paipu a me nā paipu o ka ʻōnaehana hoʻomehana. Hoʻokomo pū lākou i nā moena wela kūikawā ma luna o nā kumu me nā radiator hoʻoluʻu - he aloha kaʻawale kēia i ka poʻe ʻakaʻaka i ka pahu pahu i loko o ka pahu radiator.
ʻAʻole nānā wale ʻia nā pā uila no ka density electrolyte, akā ua hoʻokaʻawale ʻia hoʻi, ma ke ala, hiki ke lilo i mea hoʻonā hoihoi no ka poʻe kaʻa ma nā latitudes ʻākau. ʻO ka pākaukau ponoʻī he "battery" lead-acid me ka mana o 450-550 A / h a me ke kaumaha ma kahi o 70 kg!
"Fiery engine", no ka laʻana, he 16-cylinder V-ʻano "diesel", lawelawe a hoʻomākaukau no ke anu. I mea e mākaukau mau ai ke kaʻaahi no ke ala, ʻoiai ka hau a me ke anu, ma ʻOkakopa, hoʻomaka ka hoʻomākaukau pono ʻana o nā kaʻaahi no ka hoʻoilo. Ke hāʻule ka awelika o ka mahana o kēlā me kēia lā i +15 degere, hoʻohuli ʻia ka hoʻomehana ʻana o nā laina wahie ma nā locomotives diesel, a i ka wā e hāʻule ai ka thermometer i ka awelika o kēlā me kēia lā +5 degere, hiki mai ka manawa "wela".
ʻOiaʻiʻo, e like me nā lula, ʻaʻole pono e emi ka mahana o ka aila i loko o ka mīkini ma mua o 15-20 degere, ma muli o ke ʻano o ka locomotive diesel. ʻO ka haʻahaʻa haʻahaʻa o ka wela ma waho, ʻoi aku ka nui o ka wela o ka ʻenekini. Ke piʻi ka ana wela i ka pālākiō o -15 degere, ʻaʻole pio hou ka ʻenekini.
ʻO nā pūʻali o ka "wahie kaumaha" e lele ana i loko o ka paipu ʻaʻole e makaʻu i kekahi, no ka mea i loko o ka ʻōnaehana hoʻomaha o kahi locomotive diesel ʻaʻohe antifreeze a antifreeze, akā ʻo ka wai maʻamau. ʻOiai ma ka ʻākau, ʻoiai i ka hoʻoilo. No ke aha ia? ʻAe, no ka mea, pono e ninini ʻia i loko o kahi locomotive diesel ma kahi o hoʻokahi tausani lita o ka coolant, akā ʻaʻole i kiʻekiʻe ka paʻa o nā paipu a me nā pilina.
No laila, hiki ke helu i ka ʻāpana hoʻokele waiwai a hiki i ka manaʻo paʻakikī a ʻoi aku ka maikaʻi ʻaʻole e hoʻopaʻa ʻia. A he aha ka maikaʻi e pono ai ka antifreeze i ʻole e maloʻo i hoʻokahi lā, no ka laʻana, ma ka "minus 46" ma kahi o ka hapalua-station ma Siberia? ʻOi aku ka maʻalahi, ʻoiaʻiʻo, ʻaʻole e hoʻopau, no ka mea, ʻaʻole wikiwiki loa ke kaʻina hana no ka hoʻomaha ʻana i ka ʻenekini a, auwe, ʻaʻole e pau mau i ka kūleʻa. A pono ke kaʻaahi e pili i kahi papa hana koʻikoʻi, ʻoiai nā cataclysms.
