Uvavanyo lweeBrake
Ngokuhambelana nemigangatho ye-OCIMF, kubalulekile ukwenza uvavanyo lwamandla eebhuleki kwi-Mooring winch ngaphambi kokuba ihanjiswe, minyaka le, kwaye kulandelwe naluphi na ulungiso okanye iziganeko ezibalulekileyo ezinokuchaphazela amandla eebhuleki. Ngokusekelwe kwiziphumo zezi mvavanyo, ibhuleki iya kulungiswa ukuze ifikelele kumthamo we-brake we-60% ukuya kwi-80% yomthwalo omncinci wokuqhekeza (MBL) wentambo yokubambelela. Olu hlengahlengiso luqinisekisa ukuba ukuba amandla angaphandle adlula amandla eebhuleki amiselweyo, i-Mooring winch iya kukhululeka ngokuzenzekelayo, ngaloo ndlela ithintele naluphi na ukwaphuka okanye umonakalo kwi-Mooring winch.
Ividiyo yomgaqo wovavanyo lwamandla okubhrakha:
Uvavanyo kunye noLungiso lweBraking Force
Qala ngokuphonononga isiqinisekiso sekhebula kunye nolunye ulwazi olufanelekileyo, kunye nokulinganisa intsimi, ukuze uqokelele idatha yekhephu efunekayo ukuze kubalwe. I-jack kunye ne-mooring winch, ezixhotyiswe nge-pressure gauge, kufuneka zibe nendawo yokuvula yokubopha i-dry jack okanye ukusebenzisa ii-clamping bolts.
Ifomula yokubala yile ilandelayo: T = FxLI/L2 (Kn).
Kule fomula, u-T umele amandla e-jack abaliweyo (kwi-Kn), ekufuneka amiselwe ngokusekelwe kumandla okuqhekeza amancinci entambo yenqanawa. Olu balo luya kuvelisa ukufundwa kwamandla e-jack okuhambelana namandla okuqhekeza afunekayo, angama-60% okanye ama-80% amandla okuqhekeza entambo. U-F umele amandla okuqhekeza e-mooring winch (kwi-Kn). U-Ll ngumgama ukusuka embindini we-mooring winch roller ukuya embindini wentambo, obalwa njengesamba se-roller radius yangaphakathi kunye ne-cable radius. U-L2 ubonisa umgama othe tyaba ukusuka embindini we-jack bracket ukuya kwi-central axis.
Inkqubo yoVavanyo:
1. Sebenzisa i-mooring winch ukuze ususe naluphi na umswakama, igrisi, okanye ezinye izinto ezinokuphazamisa ukusebenza kwee-brake pads.
2. Qhagamshela isixhobo sokuvavanya ngokufanelekileyo kwi-winch yokubambelela, qinisekisa ukuba iibhuleki ziqiniswe kwinqanaba eliqhelekileyo, kwaye ukhulule i-clutch ye-winch.
3. Sebenzisa ijeki ukufaka uxinzelelo, kwaye ubeke iliso ekufundeni kwegeyiji yoxinzelelo xa ibhuleki iqala ukutyibilika, urekhode ixabiso elibonisiweyo.
4. Ukuba ukufundwa kwexabiso kungaphantsi kwexabiso elimiselweyo, oku kubonisa amandla angonelanga eebhuleki, nto leyo ebangela ukuba ibhuleki iqiniswe okanye ilungiswe, kulandele uvavanyo oluphindwe kabini.
5. Ukuba ukufundwa kuhambelana nexabiso elibaliweyo, kuqinisekisa ukuba amandla eebhuleki ayahlangabezana nemigangatho emiselweyo.
6. Ukuba i-mooring winch ayityibiliki ngelixa ukufundwa kwe-jack kudlula ixabiso elibaliweyo, oku kuthetha ukuba i-brake iqine kakhulu, nto leyo ebangela amandla e-brake agqithisileyo. Kule meko, amandla e-brake kufuneka ancitshiswe ngokulungisa isikrufu se-brake, kulandele uvavanyo kwakhona.
Uninzi lweenqanawa zenza uhlengahlengiso lwazo lwamandla eebhuleki, ngesiqhelo ngokuguqula isikrufu esilinganiselweyo kwisibambo seebhuleki ukuze kulawulwe ukuqina kwebhuleki ukuze kufumaneke amandla afanelekileyo.
Kwizibambo zeebhuleki ezingenazo izikrufu zomda, umntu unokuchonga indawo emva kokuba ibhuleki iqinisiwe (ehambelana namandla okubhuleka afunekayo) aze aphawule zombini isibambo sebhuleki kunye nebhendi yebhuleki kuloo ndawo (ekudaleni uphawu lomda kwiskrufu sebhuleki). Kwimisebenzi ezayo, ukulungelelanisa amanqaku aphezulu nasezantsi kuya kubonisa ukuba amandla okubhuleka kweli nqanaba ahambelana namandla okubhuleka amiselweyo.
Emva kokugqiba uvavanyo lweebhuleki, umhla wovavanyo kunye namandla okubhuleka alinganisiweyo kufuneka aboniswe ngokucacileyo kwi-winch yokubambelela kwaye abhalwe ngononophelo kwi-log yokugcinwa kwezixhobo zokubambelela.
Amanyathelo oKhuseleko lokuHamba
Ukongeza ekuvavanyweni rhoqo nasekulungiseni amandla eebhuleki, kufuneka kuqwalaselwe ezi zinto zilandelayo ngexesha lokusebenza kwe-booring:
Ukuqina kweMooring:Ukuthamba kweentambo zokubopha kudlala indima ebalulekileyo ekusasazeni amandla apheleleyo asetyenziswa yinqanawa phakathi kwemigca yokubopha. Umzekelo, ukuba iintambo ezimbini zokubopha ezinobukhulu obufanayo kunye nezinto ezifanayo zibotshelelwe kwidokhi kwicala elinye kodwa zahlukile ngobude—enye inobude obuphindwe kabini kunenye—intambo emfutshane iya kuthwala isibini kwisithathu somthwalo, ngelixa intambo ende iya kuthatha isinye kwisithathu kuphela. Ke ngoko, kuyacetyiswa ukusebenzisa iintambo zokubopha ezinobude obulinganayo nanini na xa kunokwenzeka.
Kwimeko apho iintambo ezimbini zokubopha zinobude obufanayo, zinamandla okuqhekeka afanayo, kwaye zilungelelaniswe kwicala elinye kodwa zenziwe ngezinto ezahlukeneyo—ezifana nentambo yentsimbi enobude obuyi-1.5% kunye nentambo yefayibha yokwenziwa enobude obuyi-30%—ukusasazwa komthwalo akuyi kulingana kakhulu. Intambo yentsimbi iya kuthwala i-95% yomthwalo, ngelixa intambo yefayibha iya kuxhasa i-5% kuphela. Ngenxa yoko, kubalulekile ukusebenzisa iintambo zezinto ezifanayo ukufaka imigca kwicala elinye.
Kubalulekile ukuqaphela ukuba ukuqinisekisa ukhuseleko lwenqanawa ngexesha lokubopha (ukubopha okukhuselekileyo) akubandakanyi nje ukulungelelana nokuhambelana kodwa kukwabandakanya nokuqonda ngokupheleleyo izixhobo zokubopha inqanawa, ukuqonda kakuhle imigaqo yokubopha, kunye nokucwangcisa nokwenziwa kwayo ngononophelo. Inkqubo yokugcina indawo yenqanawa kwindawo yokumisa inqanawa iqala kuphela emva kokuba inqanawa iqinisekisiwe, nto leyo ephawula ukuqala kwemisebenzi yokuqhuba ulwandle.
Amandla okuQhekelela iNtsingiselo yeSinyithi:Amandla okuqhobosha e-mooring winch ayahluka kwinqanawa nganye kwaye akhiwe ngokusekelwe kumandla "okukhulula intambo" asetyenziswa kwintambo. La mandla aphenjelelwa linani leeleya zentambo kunye necala elijikajikayo. Ubungakanani beeleya zentambo kwidrama buchaphazela kakhulu amandla okuqhobosha enkqubo yokuqhobosha. Kwiimashini zokuqhobosha ezingenazo iidrama zokwahlulahlula, amandla okuqhobosha ahlala elungelelaniswe ngokwenani elithile leeleya. Ke ngoko, kubalulekile ukuqinisekisa ukuba iintambo ziboshwe kakuhle kwidrama ngaphandle kokuqokelelwa kwelinye icala, njengoko oku kunokunciphisa amandla okuqhobosha. Kwimeko yee-winch zentambo ezixhotyiswe ngeedrama zokwahlulahlula, kubalulekile ukugcina iintambo ezingaphezulu kwesinye kwidrama yokunyusa amandla ukuthintela ukuncipha kwamandla okuqhobosha.
Ukujijwa ngokuchanekileyo kwentambo kubalulekile, njengoko ukujijwa okungafanelekanga kunokukhokelela ekunciphiseni amandla okubhuleka ukuya kuthi ga kwi-50%.
Ukusetyenziswa kweBrake ngendlela engafanelekanga:Amalungu eqela adla ngokusebenzisa iibhuleki ngempazamo ukukhulula intambo xa iphantsi koxinzelelo, nto leyo engalunganga. Olu hlobo loqheliselo lunokubangela ukuguguleka okungalinganiyo kwibhanti yebhuleki kwaye lubeka umngcipheko wokhuseleko ngenxa yendalo yalo engalawulekiyo. Ukuba umthwalo olinganayo ufakwa ngequbuliso kwintambo ekhululekileyo, inokuqhekeka, nto leyo enokubangela iingozi. Indlela efanelekileyo ibandakanya ukubopha i-clutch kunye nokusebenzisa umbane ukukhulula intambo kancinci.
Indlela Yokutsala Iingqumba Zeentambo ZeNylon:Xa ubopha intambo yenylon kwinqwaba, kuphephe ukuthembela kuphela kwiqhina elithi “∞” ukuze uqinise. Endaweni yoko, yenza ujikelezo oluphindwe kabini (abanye bacebisa ujikelezo olunye, kodwa lungadluli kabini) ukuze uqale utsale intambo kwicala lenqanawa, kulandele ukwenza iqhina elithi “∞” (kwiinqwaba ezinkulu zokubopha) okanye ujikeleze iinqwaba ezimbini kube kanye ngaphambi kokuba wenze iqhina elithi “∞” (kwiinqwaba ezincinci zokubopha). Le ndlela ivumela ulawulo olungcono lwentambo kwaye iphucula ukhuseleko.
Indawo Eyingozi Ngexesha Lokwaphuka Kwentambo:Eyona nto iyingozi kakhulu kwiintambo zefayibha zokwenziwa yenzeka xa intambo iphuka ize ibuyele umva ngokungalindelekanga. Xa intambo exinzelelweyo iqhawuka, ikhupha amandla agciniweyo, nto leyo ebangela ukuba icandelo eliphakathi kwendawo yokuqhekeka nendawo yokulawula libuyele umva ngokukhawuleza. Abantu abakwindawo yokuqhekeka basengozini yokwenzakala kakhulu okanye nokufa. Ngenxa yoko, kubalulekile ukuba abaqhubi beentambo baziphephe le ndawo inobungozi, ingakumbi xa intambo iphantsi koxinzelelo olukhulu, njengoko iintambo zefayibha zokwenziwa zinokuqhekeka ngequbuliso ngaphandle kwesilumkiso.
Izikhokelo zoKhuseleko zokubopha iimoto:Ukusebenza kwentambo entlokweni yedrama akufuneki kwenziwe ngumntu omnye. Kufuneka umntu wesibini ukuba ayisuse okanye ayibeke intambo ethe nkqo ukuze ancede umqhubi olawula idrama. Xa uphatha intambo zentsimbi okanye zenayiloni, kubalulekile ukugcina umgama okhuselekileyo ukusuka kwidrama, njengoko intambo "inokutsiba" ize ibe yingozi yokwenzakala kwiingalo zakho. Soloko ugcina umgama okhuselekileyo ukusuka kwintambo.
