Mooring winch brake force test njira ndi mfundo

Kuyesa kwa Brake

Potsatira miyezo ya OCIMF, ndikofunikira kuyesa mayeso a brake Force pa winchi ya Mooring isanaperekedwe, pachaka, ndikutsatira kukonzanso kulikonse kapena zochitika zazikulu zomwe zingakhudze mphamvu ya brake. Kutengera zotsatira za mayesowa, brake idzakonzedwa bwino kuti ikwaniritse mphamvu ya braking ya 60% mpaka 80% ya katundu wocheperako (MBL) wa chingwe cholumikizira. Kusintha kumeneku kumawonetsetsa kuti ngati mphamvu yakunja ipitilira mphamvu yoboola yomwe idasankhidwa, winchi ya Mooring imangotulutsa, potero kupewa kusweka kapena kuwonongeka kwa winchi ya Mooring.

Kanema wamayesero a Braking Force:

Kuyesa kwa Braking Force ndi Kusintha

Yambani ndikuwunikanso ziphaso za chingwe ndi zidziwitso zina zofunika, pamodzi ndi miyeso ya m'munda, kuti musonkhe zidziwitso za chipale chofewa kuti muwerengere. Winch ya jack ndi moring, yokhala ndi choyezera kuthamanga, iyenera kukhala ndi potsegulira potchingira jack youma kapena kugwiritsa ntchito ma clamping bolt.

Njira yowerengera ili motere: T = FxLI/L2 (Kn).

Munjira iyi, T imayimira mphamvu ya jack yowerengeka (mu Kn), yomwe iyenera kutsimikiziridwa kutengera mphamvu yocheperako ya chingwe cha sitimayo. Kuwerengera uku kudzapereka kuwerengera kwa jack force komwe kumafanana ndi mphamvu yoboola yomwe ikufunika, yomwe ndi 60% kapena 80% ya mphamvu yakusweka kwa chingwe. F amatanthauza mphamvu yothamanga ya winchi yolumikizira (mu Kn). Ll ndi mtunda kuchokera pakatikati pa chodzigudubuza chowongolera mpaka pakati pa chingwe, chowerengedwa ngati kuchuluka kwa radius yamkati ndi utali wa chingwe. L2 ikuwonetsa mtunda wopingasa kuchokera pakati pa jack bracket kupita ku axis yapakati.

Njira Yoyesera:

1. Gwiritsani ntchito winchi yolumikizira kuti muchotse chinyezi, mafuta, kapena zinthu zina zomwe zingasokoneze magwiridwe antchito a ma brake pads.

2. Lumikizani bwino chipangizo choyesera ndi chowongolera cholumikizira, onetsetsani kuti mabuleki amangika mpaka mulingo wokhazikika, ndikuchotsa clutch ya winchi.

3. Gwiritsani ntchito jack kuti mugwiritse ntchito kukakamiza, ndikuyang'anirani kuchuluka kwa kuthamanga kwa magazi panthawi yomwe brake ikuyamba kutsika, ndikulemba mtengo womwe wawonedwa.

4. Ngati kuwerengera kugwera pansi pa mtengo wokonzedweratu, izi zikusonyeza kuti palibe mphamvu ya brake yokwanira, zomwe zimafunika kulimbitsa kapena kukonzanso brake, ndikutsatiridwa ndi kuyesanso.

5. Ngati kuwerenga kumagwirizana ndi mtengo wowerengeka, kumatsimikizira kuti mphamvu ya brake ikugwirizana ndi zomwe zakhazikitsidwa.

6. Ngati cholumikizira cholumikizira sichikuterera pomwe kuwerenga kwa jack kupitilira mtengo womwe wawerengedwera, izi zikuwonetsa kuti brake ndi yothina mopitilira muyeso, zomwe zimapangitsa kuti mabuleki agwire mwamphamvu kwambiri. Pachifukwa ichi, mphamvu ya brake iyenera kuchepetsedwa mwa kusintha phula la brake, ndikutsatiridwa ndi retest.

Zombo zambiri zimapanga kusintha kwa mphamvu ya brake yawo, nthawi zambiri posintha malire pa chogwirira cha brake kuti athetse kulimba kwa mabuleki kuti agwire bwino ntchito.

Pa zogwirira mabuleki opanda malire zomangira, munthu akhoza kuzindikira malo pambuyo pomangirira mabuleki (logwirizana ndi ankafuna braking mphamvu) ndi chizindikiro onse ananyema chogwiririra ndi ananyema bandi pa nthawiyo (kupanga chizindikiro malire pa ananyema screw). M'tsogolomu, kugwirizanitsa zizindikiro zakumwamba ndi zapansi zidzasonyeza kuti mphamvu ya braking pamsinkhu uwu ikugwirizana ndi mphamvu yowonongeka.

Mukamaliza kuyesa mabuleki, tsiku la mayeso ndi mphamvu yoyezera ma braking ziyenera kuwonetsedwa momveka bwino pa winchi yolumikizira ndikulembedwa bwino mu chipika chokonzera zida zolumikizira.

Njira Zachitetezo cha Moring

Kuphatikiza pakuyesa pafupipafupi ndikusintha mphamvu ya brake, chidwi chiyenera kuperekedwanso kuzinthu izi panthawi yoyendetsa galimoto:

Kuthamanga kwa Moring:Kutanuka kwa zingwe zomangira kumathandizira kwambiri kugawa mphamvu zonse zomwe sitimayi imagwiritsa ntchito pakati pa mizere yoyimitsa. Mwachitsanzo, ngati zingwe ziwiri zomangirira za kukula ndi zinthu zofanana zimatetezedwa padoko mbali imodzi koma zimasiyana kutalika - imodzi kukhala yowirikiza kawiri kuposa ina - chingwe chachifupi chimatha kupirira magawo awiri mwa atatu a katunduyo, pomwe chingwe chachitali chimangotenga gawo limodzi mwa magawo atatu. Choncho, ndi bwino kugwiritsa ntchito zingwe zomangira zautali wofanana ngati kuli kotheka.

Zingwe ziwiri zomangira zimakhala zautali wofanana, zimakhala ndi mphamvu yothyoka yofanana, ndipo zimalumikizidwa mbali imodzi koma zimapangidwa kuchokera kuzinthu zosiyanasiyana - monga chingwe chachitsulo chokhala ndi elongation ya 1.5% ndi chingwe chopangidwa ndi 30% -kugawa katundu kudzakhala kosiyana kwambiri. Chingwe chachitsulo chidzanyamula 95% ya katundu, pamene chingwe cha fiber chidzangogwira 5%. Chifukwa chake, ndikofunikira kugwiritsa ntchito zingwe zazinthu zomwezo pomangirira mizere mbali imodzi.

M’pofunika kuzindikira kuti kuonetsetsa kuti sitimayo ili ndi chitetezo pa nthawi yoimika (yoima motetezeka) sikumangotanthauza kugwilizana ndi kusasinthasintha, komanso kumvetsetsa bwino zipangizo zoikira ngalawayo, kudziŵa bwino mfundo zoimika m’sitimayo, ndiponso kulinganiza mosamalitsa ndi kachitidwe kake. Njira yosungira malo osungiramo sitimayo imayambira pokhapokha chombocho chikatetezedwa, zomwe zikuwonetsa kuyamba kwa machitidwe oyendetsa sitimayo.

Mooring Winch Braking Force:Mphamvu yamabuleki ya winchi yolumikizira imasiyanasiyana pachombo chilichonse ndipo imapangidwa motengera mphamvu ya "kumasula chingwe" pa chingwe. Mphamvuyi imakhudzidwa ndi kuchuluka kwa zigawo za chingwe ndi njira yokhotakhota. Kuchuluka kwa zigawo za chingwe pa ng'oma kumakhudza kwambiri mphamvu yama braking system. Kwa makina osungira omwe alibe ng'oma zolekanitsa, mphamvu ya braking nthawi zambiri imayesedwa pazigawo zingapo. Chifukwa chake, ndikofunikira kuwonetsetsa kuti zingwezo zakulungidwa bwino pa ng'oma popanda kuwunjikana mbali imodzi, chifukwa izi zitha kuchepetsa mphamvu yakuboola. Pankhani ya ma winchi okhala ndi ng'oma zolekanitsa, ndikofunikira kuti musapitirire chingwe chimodzi pa ng'oma yamphamvu kuti muchepetse mphamvu yoboola.

Kumangirira koyenera kwa chingwe ndikofunikira, chifukwa kupendekera kosayenera kungayambitse kuchepa kwa mphamvu ya braking ndi 50%.

Kugwiritsa Ntchito Mabuleki Molakwika:Ogwira ntchito nthawi zambiri amagwiritsa ntchito mabuleki molakwika kuti amasule chingwe chikakhala chovuta, chomwe ndi njira yolakwika. Mchitidwewu ungapangitse kuvala kosagwirizana pa lamba wa brake ndipo kumabweretsa ngozi zachitetezo chifukwa cha kusalamulirika kwake. Ngati katundu woyenerera aikidwa mwadzidzidzi pa chingwe chosamasulidwa, akhoza kudumpha, zomwe zimapangitsa kuti pakhale ngozi. Njira yoyenera imaphatikizapo kugwirizanitsa ndi clutch ndikugwiritsa ntchito mphamvu kuti mutulutse chingwecho pang'onopang'ono.

Njira Yokokera Mulu Wa Nayiloni:Mukamamanga chingwe cha nayiloni pa mulu, pewani kudalira mfundo ya “∞” pomangitsa. M'malo mwake, pangani makhotolo awiri (omwe ena amalimbikitsa kutembenuka kumodzi, koma osapyola kuwiri) kuti mukoke chingwe kumbali ya sitimayo, kenako ndikupanga mfundo "∞" (pamilu yayikulu) kapena kukulunga milu iwiri kamodzi musanapange mfundo "∞" (pamilu yaying'ono yolumikizira). Njirayi imalola kuyendetsa bwino chingwe ndikuwonjezera chitetezo.

Malo Owopsa Pakusweka Kwa Chingwe:Mbali yowopsa kwambiri ya zingwe zopangira ulusi zimachitika pamene chingwe chaduka ndikubwerera mosayembekezereka. Chingwe chopanikizika chikaduka, chimatulutsa mphamvu zosungidwa, zomwe zimapangitsa kuti gawo pakati pa malo opumira ndi malo owongolera libwezere mwachangu. Anthu omwe ali m'dera lozungulira ali pachiwopsezo chovulala kwambiri kapena kufa kumene. Chifukwa chake, ndikofunikira kuti oyendetsa chingwe achoke pamalo owopsawa, makamaka chingwe chikavutitsidwa kwambiri, chifukwa zingwe zopangira zimatha kuthyoka mwadzidzidzi popanda chenjezo.

Malangizo a Chitetezo pa Mooring:Kugwira ntchito kwa chingwe pamutu wa ng'oma sikuyenera kuchitidwa ndi munthu mmodzi. Munthu wachiwiri ndi wofunikira kuti achotse kapena kupereka kutsetsereka kwa chingwe kuti athandizire woyendetsa ng'oma. Mukagwira zingwe za waya kapena nayiloni, ndikofunikira kuti mukhale kutali ndi ng'oma, chifukwa chingwe "chitha kudumpha" ndikuyika chiwopsezo cha kuvulala kwa manja anu. Nthawi zonse khalani kutali ndi chingwe.
