Mu ntchito zapamadzi zamakono, chitetezo, kudalirika, ndi kutsatira miyezo ya chilengedwe sizilinso zofunikira; ndizofunikira kwambiri. Chinthu chomwe nthawi zambiri chimaiwalika koma chofunikira kwambiri mu makina omangira ndi chingwe cha mabuleki cha winch chomangira. Makamaka, mabuleki osagwiritsa ntchito asbestos aonekera ngati muyezo wamakampani chifukwa cha magwiridwe antchito awo abwino komanso kugwirizana ndi malamulo apadziko lonse lapansi achitetezo. Nkhaniyi ikufotokoza za ntchito, kapangidwe, ndi ubwino waukulu wa mabuleki osagwiritsa ntchito asbestos, kuthandiza eni sitima ndi ogwira ntchito kumvetsetsa kufunika kwa gawoli.
Kodi Chipinda Chosungira Mabuleki cha Winch Chokhala ndi Mooring Chimapanga Chiyani?
A chingwe cholumikizira mabuleki cha winchndi chinthu chomangirira chomwe chimayikidwa mkati mwa dongosolo lomangira la winch yomangira. Ntchito yake yayikulu ndikupanga kukangana kolamulidwa pakati pa ng'oma ya brake ndi makina omangira, zomwe zimathandiza winch kugwira kapena kumasula zingwe zomangira bwino pamene ikugwedezeka.
Mwachidule, chombo chikakokedwa kapena kumangidwa, chingwe cha mabuleki chomangirira chimatsimikizira kuti zingwe kapena mawaya azikhalabe pamalo ake, ngakhale atakumana ndi katundu wosinthika kuchokera ku mafunde, mafunde, kapena mphepo. Ngati palibe chingwe chodalirika cha mabuleki, ntchito yonse yomangirira ikhoza kukhala pachiwopsezo.
N’chifukwa Chiyani Muyenera Kusankha Zinthu Zosakhala za Asbestos?
M'mbuyomu, mabuleki ankapangidwa pogwiritsa ntchito asbestos chifukwa cha kukana kutentha komanso kulimba kwake. Komabe, asbestos tsopano imadziwika kuti ndi chiwopsezo ku thanzi la anthu komanso chilengedwe. Chifukwa chake, malamulo apadziko lonse lapansi—monga kusintha kwa SOLAS ndi malamulo a IMO—apangitsa kuti pakhale kusintha kwa njira zina zosakhala asbestos.
Mabuleki amakono omwe si a asbestos amapangidwa pogwiritsa ntchito zipangizo zamakono zophatikizika, zomwe nthawi zambiri zimaphatikizapo:
1. Ulusi wa viscose
2. Ulusi wagalasi
3. Mawaya amkuwa
4. Ma resini omatira ogwira ntchito kwambiri
Kuphatikiza kumeneku kumabweretsa zinthu zokhuthala, zosinthasintha pang'ono zomwe zimapereka mphamvu zabwino kwambiri zamakanika ndi kutentha popanda zoopsa zolumikizidwa ndi asbestos.
Ntchito Zazikulu za Ma Brake Akunja Osakhala Asbestos
1. Kugwira Ntchito Kodalirika kwa Mikangano
Ntchito yaikulu ya brake lineup ndikupereka coefficient yokhazikika komanso yodziwikiratu ya kukangana. Ma linens omwe si a asbestos amatsimikizira kuti kukangana kuli kokhazikika pa kutentha kwakukulu, zomwe zimathandiza kuwongolera molondola panthawi yogwirira ntchito.
2. Kutha Kugwira Katundu
Makina omangirira zinthu amakhala ndi mphamvu zambiri. Ma brake closure amafunika kuti apirire kuthamanga kwambiri pamwamba pomwe akugwirabe ntchito. Zipangizo zomwe si za asbestos zimaonetsa kukhazikika kwakukulu pamene katunduyo akunyamula, zomwe zimathandiza kuti zisagwe ngakhale m'mikhalidwe yovuta.
3. Kukana Kutentha
Kukangana kumabweretsa kutentha pakagwa mabuleki. Mabuleki osakhala a asbestos amapangidwa kuti azigwira ntchito bwino pa kutentha koyenera mpaka 200°C ndipo amatha kupirira kutentha kwadzidzidzi kufika 250°C, kuonetsetsa kuti ntchitoyo ikuyenda bwino popanda kuwonongeka.
4. Kukana Kuvala
Kugwiritsa ntchito nthawi zonse kungayambitse kuwonongeka. Zingwe zapamwamba zopanda asbestos zimapangidwa kuti zisawonongeke, motero zimatalikitsa nthawi yogwira ntchito ndikuchepetsa zosowa zosamalira.
Ubwino Waukulu wa Ma Brake Lining Osakhala Asbestos Mooring Winch
1. Chitetezo Chowonjezereka
Chitetezo ndi chofunika kwambiri pa ntchito zapamadzi. Mabuleki osagwiritsa ntchito asbestos amapereka magwiridwe antchito odalirika a mabuleki, kuchepetsa chiopsezo cha kulephera mwadzidzidzi kapena kutulutsidwa kwa mizere yosalamulirika. Makhalidwe awo okhazikika amatsimikizira kuti amagwira ntchito bwino nthawi zonse.
2. Kutsatira Malamulo a Zachilengedwe
Zipangizo zomwe sizili za asbestos zimatsatira malamulo apadziko lonse lapansi monga:
1. Misonkhano ya IMO yokhudza chitetezo cha sitima ndi kubwezeretsanso zinthu
2. Miyezo ya ISO yokhudza chitetezo cha zinthu
3. Zofunikira za SOLAS
Izi zimawaika ngati chisankho chokhazikika kwa eni sitima omwe akufuna kutsatira malamulo apadziko lonse okhudzana ndi chilengedwe ndi chitetezo.
3. Kulimba Kwambiri
Chifukwa cha kapangidwe kake kophatikizana, zophimba zopanda asbestos zimapereka:
1. Kukana kutentha kwambiri
2. Umphumphu wamphamvu wa makina
3. Kutsika kwa kuvala
Izi zimapangitsa kuti ntchito ikhale yayitali komanso kuti ndalama zosinthira zichepe.
4. Kusinthasintha kwa Ntchito Zonse
Ngakhale kuti amagwiritsidwa ntchito kwambiri pomangirira ma winchi ndi magalasi akumbuyo, ma brake linings osagwiritsa ntchito asbestos ndi oyeneranso:
1. Ma cranes ndi ma hoist
2. Zipangizo zobowolera
3. Makina a mafakitale
4. Zikepe ndi zida za migodi
Kusinthasintha kumeneku kukuwonetsa kudalirika kwawo pa ntchito zosiyanasiyana zolemera.
5. Kugwirizana ndi Malo Ambiri
Mabuleki osakhala a asbestos amagwira ntchito bwino ndi zinthu zomwe zimapezeka kwambiri monga chitsulo chosungunuka ndi chitsulo. Kuti mugwire bwino ntchito, ndibwino kugwiritsa ntchito malo olumikizirana okhala ndi kuuma kwa 180 Brinell kapena kupitirira apo.
6. Kukula Kosinthasintha ndi Kukonza Kosavuta
Ma linens awa amapezeka mu makulidwe osiyanasiyana (5mm–30mm), m'lifupi (30mm–550mm), ndi kutalika kwa ma roll, zomwe zimathandiza kusintha makina osiyanasiyana a winch. Angathenso kukonzedwa ndi zida zodulira wamba, zomwe zimathandiza kukhazikitsa ndi kukonza mosavuta.
Zoganizira za Ntchito
Kuti muwongolere magwiridwe antchito, ndikofunikira kugwiritsa ntchito mabuleki mkati mwa malire omwe akulimbikitsidwa:
1. Liwiro lotsetsereka: pansi pa 12 m/s
2. Kupanikizika kwa pamwamba: pansi pa 200 N/cm²
3. Kutentha: mkati mwa magawo otchulidwa
Komanso, magwiridwe antchito a makinawa amatha kusiyana kutengera ngati makinawa amagwira ntchito m'malo ouma kapena omizidwa ndi mafuta, ndipo kupsinjika kochepa kumayembekezeredwa m'malo opaka mafuta.
Mapeto
Mabuleki opangidwa ndi mawinchi osagwiritsidwa ntchito ndi asbestos akusonyeza kupita patsogolo kwakukulu muukadaulo wachitetezo cha m'madzi. Mwa kuphatikiza kukhazikika kwakukulu kwa kukangana, kukana kutentha kwambiri, komanso kutsatira malamulo a chilengedwe, amapereka njira yodalirika yogwiritsira ntchito zombo zamakono.
Kwa eni sitima ndi ogwira ntchito, kuyika ndalama mu mabuleki apamwamba osagwiritsa ntchito asbestos kumaposa kutsatira malamulo okha—ndi nkhani yoteteza ogwira ntchito, katundu, ndi zombo m'malo ovuta a m'nyanja. Pamene gawo la zapamadzi likupitirira kupita patsogolo, zipangizo zatsopanozi zidzapitirira kukhala chinthu chofunikira kwambiri pa ntchito zomangira zotetezeka komanso zogwira mtima.
