Imam motorni brod od deset metara s unutarnjim motorom i hidrauličnim kormilom. Iako je ta tehnologija za pokretanje kormila dosta sigurna, brine me što mi je jedan meštar kazao da bih u slučaju kvara na sustavu hidraulike ostao bez ikakve mogućnosti kormilarenja. List kormila je u moru, a pomoćna argola nije predviđena, pa ne bih mogao mehanički upravljati. Čuo sam da ipak postoje neka rješenja da se omogući mehaničko kormilarenje, pa bih molio vaš savjet?

Lovro K., Zadar

Istina, kormilo pokretano hidraulikom dosta je pouzdano i rijetko se kvari, a to što vam je meštar kazao da bi u slučaju kvara ostali bez ikakve mogućnosti kormilarenja, samo je donekle u pravu. Naime, još uvijek imate zavlačno sidro kojim, uz korekciju brzine, ipak nekako možete kontrolirati kurs. Zavlačno sidro prvenstveno služi kako bi se, pušteno s pramca, plovilo bez pogona zadržalo u smjeru vjetra i valova.

Međutim, kada se s dosta konopa pusti po krmi, njime se može i održavati kurs. Pomicanjem hvatišta po krmi ili bokovima može se i mijenjati smjer. Ako u plovilu nemate originalno zavlačno ili kako ga još nazivaju olujno sidro, možete ga pokušati improvizirati od opreme koju imate sa sobom. Naravno da je ovakav sustav upravljanja dosta kompliciran, pa je za ove situacije bolje imati pripremljen neki jednostavniji način kormilarenja, a to je svakako rezervna ručna argola.

Kvadratni profil

Sustav sajli za pokretanje kormila može se kvariti iz više razloga, pa je na takvim brodicama uglavnom već predviđena mogućnost jednostavne montaže pomoćne ručne argole. Radi lakšeg pristupa, na palubi je neposredno iznad osovine kormila ugrađen široki čep, a kvadratni profil na samom vrhu osovine upravo je predviđen da se na njega jednostavno uglavi pomoćna argola. Ovdje sajle stvaraju minimalan otpor, a ako blokiraju rad kormila lako ih je odspojiti.

Kod jednostavnih hidrauličnih kormila timun je spojen na osovinu pumpe koja je s obje strane cijevima priključena na diferencijalni ili dvoradni hidraulični cilindar, a klipnjača cilindra direktno spojena na polugu za okretanje osovine kormila. Okretanjem timuna u jednu ili drugu stranu ulje s tlačne strane pomiče klip, klipnjača se uvlači ili izvlači, a osovina zakreće list kormila ulijevo ili udesno.

Ponekad se dogodi da u taj zatvoreni sustav uđe zrak, a to se u plovidbi primijeti kada je kod skretanja timun potrebno okretati više negoli je to uobičajeno. Sustav je negdje popustio, nešto ulja je iscurilo i ušao je zrak. To je manji problem i za plovidbu nije toliko opasan, ali je kvar potrebno što prije otkloniti jer će s vremenom u sustavu biti sve više zraka i kormilarenje će postati sve kompliciranije.

Otpor ulja

Veći je problem kada sustav iz nekog razloga više ne funkcionira. Za takve situacije ipak treba imati rezervnu ručnu argolu i relativno jednostavan pristup osovini kormila, slično kao i kod kormila pokretanih sajlama.

Ugrađeni bypass ventil

Međutim, ulje u sustavu sada stvara veliki otpor i argolu je teško pomaknuti. Taj je otpor potrebno anulirati, a ako je pristup osovini nesmetan, najjednostavnije je s nje odspojiti klipnjaču i kormilo je slobodno. Međutim, na manjim je brodicama taj prilaz kormilu uglavnom kompliciran, naročito dok se brodica valja po valovima. Rješenje je ugradnja bypass ventila. Njime se obje strane cilindra povežu, a kada se otvori ulje slobodno cirkulira s jedne strane klipa na drugu i argoli ne stvara značajan otpor. Naravno, ovaj ventil treba ugraditi na lako pristupačno mjesto, ali ga i osigurati da se ne može slučajno otvoriti.

Imam motorni brod od deset metara s unutarnjim motorom i hidrauličnim kormilom. Iako je ta tehnologija za pokretanje kormila dosta sigurna, brine me što mi je jedan meštar kazao da bih u slučaju kvara na sustavu hidraulike ostao bez ikakve mogućnosti kormilarenja. List kormila je u moru, a pomoćna argola nije predviđena, pa ne bih mogao mehanički upravljati. Čuo sam da ipak postoje neka rješenja da se omogući mehaničko kormilarenje, pa bih molio vaš savjet?

Istina, kormilo pokretano hidraulikom dosta je pouzdano i rijetko se kvari, a to što vam je meštar kazao da bi u slučaju kvara ostali bez ikakve mogućnosti kormilarenja, samo je donekle u pravu. Naime, još uvijek imate zavlačno sidro kojim, uz korekciju brzine, ipak nekako možete kontrolirati kurs. Zavlačno sidro prvenstveno služi kako bi se, pušteno s pramca, plovilo bez pogona zadržalo u smjeru vjetra i valova.

Međutim, kada se s dosta konopa pusti po krmi, njime se može i održavati kurs. Pomicanjem hvatišta po krmi ili bokovima može se i mijenjati smjer. Ako u plovilu nemate originalno zavlačno ili kako ga još nazivaju olujno sidro, možete ga pokušati improvizirati od opreme koju imate sa sobom. Naravno da je ovakav sustav upravljanja dosta kompliciran, pa je za ove situacije bolje imati pripremljen neki jednostavniji način kormilarenja, a to je svakako rezervna ručna argola.

Kvadratni profil

Sustav sajli za pokretanje kormila može se kvariti iz više razloga, pa je na takvim brodicama uglavnom već predviđena mogućnost jednostavne montaže pomoćne ručne argole. Radi lakšeg pristupa, na palubi je neposredno iznad osovine kormila ugrađen široki čep, a kvadratni profil na samom vrhu osovine upravo je predviđen da se na njega jednostavno uglavi pomoćna argola. Ovdje sajle stvaraju minimalan otpor, a ako blokiraju rad kormila lako ih je odspojiti.

Kod jednostavnih hidrauličnih kormila timun je spojen na osovinu pumpe koja je s obje strane cijevima priključena na diferencijalni ili dvoradni hidraulični cilindar, a klipnjača cilindra direktno spojena na polugu za okretanje osovine kormila. Okretanjem timuna u jednu ili drugu stranu ulje s tlačne strane pomiče klip, klipnjača se uvlači ili izvlači, a osovina zakreće list kormila ulijevo ili udesno.

Ponekad se dogodi da u taj zatvoreni sustav uđe zrak, a to se u plovidbi primijeti kada je kod skretanja timun potrebno okretati više negoli je to uobičajeno. Sustav je negdje popustio, nešto ulja je iscurilo i ušao je zrak. To je manji problem i za plovidbu nije toliko opasan, ali je kvar potrebno što prije otkloniti jer će s vremenom u sustavu biti sve više zraka i kormilarenje će postati sve kompliciranije.

Otpor ulja

Veći je problem kada sustav iz nekog razloga više ne funkcionira. Za takve situacije ipak treba imati rezervnu ručnu argolu i relativno jednostavan pristup osovini kormila, slično kao i kod kormila pokretanih sajlama.

Međutim, ulje u sustavu sada stvara veliki otpor i argolu je teško pomaknuti. Taj je otpor potrebno anulirati, a ako je pristup osovini nesmetan, najjednostavnije je s nje odspojiti klipnjaču i kormilo je slobodno. Međutim, na manjim je brodicama taj prilaz kormilu uglavnom kompliciran, naročito dok se brodica valja po valovima. Rješenje je ugradnja bypass ventila. Njime se obje strane cilindra povežu, a kada se otvori ulje slobodno cirkulira s jedne strane klipa na drugu i argoli ne stvara značajan otpor. Naravno, ovaj ventil treba ugraditi na lako pristupačno mjesto, ali ga i osigurati da se ne može slučajno otvoriti.
