Abubuwan da ke Shafar Saurin Jirgin Ruwa
Saurin jirgin ruwa muhimmin alama ne a duniyar jigilar kaya, ga jiragen ruwa na 'yan kasuwa, jiragen fasinja, har ma da jiragen ruwa na soja. Sauri ba wai kawai yana tantance saurin jirgin ruwa zuwa inda yake ba, har ma yana shafar ingancin mai, jadawalin aiki, aminci, da kuma farashin jigilar kaya gaba ɗaya. Duk da haka, saurin jirgin ba ƙayyadadden ƙima ba ne wanda za a iya cimmawa a kowane lokaci; abubuwa da yawa masu alaƙa suna tasiri ga ikon jirgin ruwa na kewaya ruwa. Ga manyan abubuwan da ke tasiri ga saurin jirgin.
1. Tsarin jirgin ruwa
Ɗaya daga cikin manyan abubuwan da ke ƙayyade saurin jirgin ruwa shine siffar da ƙirar jirgin. Tsarin jirgin ruwa mai tsari ta hanyar iska, ko kuma daidai, "a fannin hydrodynamic," yana rage jan ruwa, yana bawa jirgin damar yin tafiya da sauri da irin wannan ƙarfin.
Wasu daga cikin abubuwan da ke haifar da tasirin wannan dabarar sun haɗa da:
– Siffar baka: Bakan da aka tsara don yanke raƙuman ruwa zai rage juriya lokacin da jirgin ya motsa.
– Faɗin jirgin ruwa (beam): Jiragen ruwa masu faɗi da yawa suna da juriya mai yawa, kodayake kwanciyar hankalinsu yana ƙaruwa.
– Tsarin ruwa: Yayin da jirgin ya nutse cikin ruwa, haka nan yake ƙara yawan gogayya tsakanin saman da ruwan.
– Nau'in jirgin ruwa: Jiragen ruwa masu matsugunan da ke motsawa (wanda aka saba gani a manyan jiragen ruwa masu kaya) suna da iyaka ta gudu daban-daban idan aka kwatanta da jiragen ruwa masu tsara jirgin ruwa (misali jiragen ruwa masu sauri) waɗanda ke "ɗaga" wani ɓangare na jirgin ruwa lokacin da suke tafiya da sauri.
Tsarin jirgin ruwa kuma ya dogara ne da tsawon jirgin. Gabaɗaya, jiragen ruwa masu tsayi suna da yuwuwar samun saurin gudu mafi girma saboda raƙuman ruwa da suke samarwa sun fi tsayi kuma juriyar yin raƙuman ruwa na iya zama mafi inganci a wani saurin da aka bayar.
2. Tsarin wutar lantarki da injin turawa
Gudun jirgin ruwa ya dogara sosai akan ikon tsarin turawa na samar da turawa. Injin mai ƙarfi sosai zai iya ƙara gudu, amma wannan ƙaruwar ba koyaushe take layi ba. Wato, ƙarfin injin ninkawa baya ninka gudu ta atomatik, yayin da juriyar ruwa ke ƙaruwa da sauri.
Tsarin turawa ya haɗa da:
– Nau'in injin (dizal, injin turbin gas, na'urar haɗaka, lantarki).
– Yanayin injin da aikin sa: Injin da ba a kula da shi ba zai rasa inganci da kuzari.
– Tsarin watsawa da shaft: Asarar makamashi na iya faruwa a cikin kayan aikin injiniya kafin wutar ta isa ga propeller.
– Propeller: Diamita, ƙararrawa, adadin ruwan wukake, da ƙira suna shafar ingancin tururin. Propeller wanda bai dace da halayen jirgin ba zai iya haifar da cavitation da asarar wutar lantarki.
Baya ga na'urorin propeller na gargajiya, wasu jiragen ruwa suna amfani da jiragen ruwa masu saukar ungulu, na'urorin azimuth, ko na'urorin propulsion, kowannensu yana da nasa halaye dangane da gudu, iya motsawa, da kuma inganci.
3. Juriyar ruwa
Juriyar ruwa ita ce babbar "abokiyar gaba" idan jirgin ruwa yana tafiya. Wannan juriyar ta ƙunshi nau'ikan da dama:
– Juriya ta gogayya: Yana faruwa ne saboda gogayya tsakanin saman kwanyar da ruwa. Girman saman kwanyar da aka jika, haka nan gogayya ta fi girma.
– Juriyar Raƙuman Ruwa: Jiragen ruwa suna ƙirƙirar raƙuman ruwa yayin da suke motsawa. A wasu saurin gudu, kuzarin da ake buƙata don "tura" raƙuman ruwa yana ƙaruwa sosai.
– Juriya ga siffar: Yana da alaƙa da siffar kwanyar da kuma yadda ruwa ke gudana a kusa da ita.
– Ƙarin juriya (juriyar kayan haɗin): Ya fito ne daga ƙarin abubuwan da aka haɗa kamar su madaukai, masu daidaita abubuwa, skeg, da sauran gine-gine a ƙarƙashin ruwa.
Rage jan hankali shine mabuɗin ƙara gudu ba tare da ƙara yawan amfani da mai ba.
4. Yanayin saman kwanson (ƙura)
Tsaftataccen saman harsashi yana ba da damar kwararar ruwa mai santsi. Duk da haka, a aikace, ɓangarorin jiki galibi suna girma da barnacles, moss, algae, ko wasu halittu na ruwa, wanda ke haifar da gurɓatawa. Gurɓatawa yana ƙara jan hankali kuma yana iya rage gudu sosai, koda lokacin da injin ɗin ke aiki a irin wannan ƙarfin.
Saboda haka, magunguna kamar:
- tsaftace bututun,
- fenti mai hana lalata,
- da kuma duba lokaci-lokaci yayin da ake shiryawa
muhimmin abu ne wajen kiyaye ingantaccen saurin jirgin ruwa.
5. Rarraba kaya da nauyi
Da zarar jirgin ya yi nauyi, to, girman jirgin da yake yi zai yi girma, kuma girman yankin saman jirgin da ke nutsewa a cikin ruwa. Wannan yana ƙara jan hankali da rage gudu. Misali, jiragen ruwa masu ɗaukar kaya sau da yawa suna fuskantar bambancin gudu tsakanin yanayin da aka cika lodi da kuma yanayin da ba a cika ɗaukar nauyi ba.
Baya ga jimillar nauyin da aka ɗauka, rarraba nauyi ma yana da matuƙar muhimmanci. Nauyin da ba shi da daidaito zai iya shafar yankewa (karkatar da baka ko bayan jiki) da kuma kwanciyar hankali, yana ƙara jan jiki da kuma sanya jirgin ruwa ya zama mara inganci.
6. Yanayi da yanayin raƙuman ruwa
Yanayi yana da tasiri sosai ga saurin jirgin ruwa. Raƙuman ruwa masu ƙarfi, iska mai ƙarfi, da kuma raƙuman ruwa masu ƙarfi na iya rage gudu da kuma ƙara yawan amfani da mai.
Wasu tasirin yanayi sun haɗa da:
- Iska mai ƙarfi tana ƙara jan hankali da rage gudu.
- Iskar da ke juyawa daga baya na iya taimakawa, kodayake tasirinsa ya dogara ne akan ƙirar jirgin ruwa da kuma jirgin kyauta.
– Raƙuman ruwa suna sa jirgin ya bugi ruwa (slamming) ko kuma ya fuskanci motsin jifa da birgima wanda ke rage inganci.
– Rashin gani sosai zai iya tilasta wa jiragen ruwa rage gudu domin kare lafiya.
A cikin mawuyacin hali, kyaftin ɗin zai iya yin hanyar zirga-zirgar yanayi, wanda ke nufin zaɓar hanya mai ɗan tsayi amma mafi aminci kuma mafi kwanciyar hankali don kiyaye jirgin cikin inganci.
7. Ruwan teku da raƙuman ruwa
Ruwan teku na iya zama "kari" da kuma "cikas" ga jiragen ruwa. Idan ruwan yana gudana a hanya ɗaya, saurin da ke kan ƙasa yana ƙaruwa. Akasin haka, ruwan da ke juyawa na iya rage shi, har ma yana buƙatar jirgin ya kashe ƙarin kuzari don ci gaba da tafiyarsa.
Ruwa yana taka rawa, musamman a cikin ruwa mai kunkuntar, magudanar ruwa, ko tashoshin jiragen ruwa. A wasu yankuna, ruwan sama yana da ƙarfi sosai kuma yana iya yin tasiri ga dabarun tashi na jirgin ruwa don samun kwararar ruwa mai kyau.
8. Zurfi da halayen ruwa (tasirin ruwa mara zurfi)
Saurin jirgin ruwa a cikin ruwa mai zurfi sau da yawa ya bambanta da na buɗaɗɗen ruwa. A cikin ruwa mai zurfi, tasirin ruwan mara zurfi yana faruwa, wanda ke ƙara jan ruwa kuma yana iya canza halayen jirgin ruwa, gami da iya motsawa. Ruwan da aka "matse" tsakanin kwanson ruwa da kuma gefen teku yana canza yanayin kwararar ruwa, yana buƙatar ƙarin ƙarfi don tafiya a daidai gudun.
Wannan lamari yana da matuƙar muhimmanci ga manyan jiragen ruwa lokacin da suke ketare magudanan ruwa, koguna ko hanyoyin jigilar kaya marasa zurfi.
9. Yanayin fasaha da kula da jirgin
Bayan injin, wasu abubuwa da yawa suna shafar saurin:
- Tsarin tuƙi da tuƙi mara kyau yana ƙara jan hankali.
– Abubuwan da ke haifar da matsala a bearings, shafts da tsarin shafawa suna ƙara asarar makamashi.
– Tsarin sanyaya injin mara inganci zai iya rage aiki.
– Lalacewar propeller kamar lanƙwasawa ko zaizayar ƙasa zai rage tururin.
Jirgin ruwa mai kyau yana iya kiyaye saurin ƙirarsa na tsawon lokaci kuma yana guje wa ɓatar da mai.
10. Abubuwan da ke aiki: dabarun gudu da ingancin mai
A cikin jigilar kaya ta zamani, neman mafi girman gudu ba koyaushe bane babban fifiko. Yawancin masu aiki suna amfani da manufar tururi a hankali, sarrafa jiragen ruwa a ƙananan gudu don adana mai da rage hayaki. Wannan dabarar tana da tasiri ta hanyar farashin mai, jadawalin da aka tsara, da manufofin muhalli.
Shawarwarin aiki kamar:
– zaɓi rpm na injin,
- saita mafi kyawun kayan ado,
- kuma ƙayyade hanyar da lokacin tafiya
zai iya canza ingantaccen saurin jirgin da kuma ingancinsa gaba ɗaya.
Kammalawa
Saurin jirgin ruwa yana tasiri ne ta hanyar haɗakar abubuwan fasaha, muhalli, da kuma ayyuka. Tsarin jirgin ruwa, ƙarfin injin, yanayin propeller, tsaftar jirgin ruwa, kaya, da abubuwan waje kamar yanayi da kwararar ruwa na teku duk suna taka muhimmiyar rawa. Saboda abubuwa da yawa suna da alaƙa, ƙaruwar gudu ba wai kawai batun ƙara ƙarfin injin ba ne; inganta ƙira, kulawa ta yau da kullun, sarrafa kaya, da dabarun tafiya mai wayo sune mabuɗin cimma saurin da ya dace, aminci, da inganci.
Idan kana so, zan iya daidaita wannan labarin zuwa wani takamaiman yanayi - misali, aikin makaranta, rahoton fasaha na jigilar kaya, ko wani sanannen rubutu a shafin yanar gizo - tare da misalan misalai da taƙaitaccen bayani.
