Ke Eng e Bopang Brake Lining ea Winch e Otlolohang?
A winch e khomaretsang brake fasteningke thepa ea khohlano e kentsoeng ka har'a sistimi ea ho brake ea winch ea ho tlama. Mosebetsi oa eona o ka sehloohong ke ho hlahisa khohlano e laoloang pakeng tsa teramo ea brake le mokhoa oa ho brake, e leng se nolofalletsang winch ho tšoara kapa ho lokolla lithapo tsa ho tlama ka mokhoa o sireletsehileng tlas'a khatello.
Ka mantsoe a sebetsang, ha sekepe se kentsoe kapa se tlamiloe, lesela la brake la winch le tiisa hore lithapo kapa lithapo li lula li le sebakeng se tiileng, leha li le tlas'a meroalo e matla e tsoang maqhubung, maqhubung a leoatleng, kapa moeeng. Ha ho se na lesela le tšepahalang la brake, ts'ebetso eohle ea ho khomaretsa e tla be e le kotsing.
Hobaneng o lokela ho kgetha dintho tse seng tsa Asbestos?
Ho tloha khale, masela a brake a ne a etsoa ka ho sebelisa asbestos ka lebaka la ho hanyetsa mocheso le ho tšoarella ha eona. Leha ho le joalo, asbestos joale e tsejoa haholo e le tšokelo bophelong ba batho le tikolohong. Ka lebaka leo, melaoana ea machaba—joalo ka liphetoho tsa SOLAS le litumellano tsa IMO—e susumelitse phetoho ho mekhoa e meng e seng ea asbestos.
Lithapo tsa sejoale-joale tsa brake tse seng tsa asbestos li entsoe ka thepa e tsoetseng pele e kopaneng, eo hangata e kenyeletsang:
1. Faeba ea viscose
2. Faeba ea khalase
3. Lithapo tsa koporo
4. Li-resin tse khomarelang tse sebetsang hantle
Motswako ona o fella ka thepa e teteaneng, e tenyetsehang hanyane e fanang ka thepa e ikhethang ea mechini le mocheso ntle le likotsi tse amanang le asbestos.
Mesebetsi ea Bohlokoa ea Li-Lining tsa Li-Brake tse sa Sebeleng Asbestos
1. Tshebetso e Tšepahalang ea Khohlano
Karolo e ka sehloohong ea lesela la brake ke ho fana ka tekanyo e tsitsitseng le e ka boleloang esale pele ea khohlano. Masela a seng a asbestos a netefatsa maemo a khohlano a tsitsitseng holim'a mocheso o pharaletseng, a nolofalletsa taolo e nepahetseng nakong ea mesebetsi ea ho khomaretsa.
2. Bokhoni ba ho Tšoara Mojaro
Litsamaiso tsa ho khomaretsa li na le matla a maholo. Lithapo tsa brake lia hlokahala ho mamella khatello e phahameng ea bokaholimo ha li ntse li tšoara. Thepa e seng ea asbestos e bontša botsitso bo tsotehang tlas'a mojaro, e thibelang ho thella esita le maemong a thata.
3. Khanyetso ea Mocheso
Khohlano e hlahisa mocheso nakong ea ho brake. Lithapo tsa brake tse seng tsa asbestos li entsoe hore li sebetse hantle mochesong o tloaelehileng ho fihlela ho 200°C 'me li ka mamella mocheso o potlakileng ho fihla ho 250°C, ho netefatsa ts'ebetso e sireletsehileng ntle le ho senyeha.
4. Khanyetso ea ho roala
Tšebeliso e tloaelehileng e ka lebisa ho tsofaleng le ho taboheng. Lithapo tsa boleng bo holimo tse seng tsa asbestos li etselitsoe ho hanela ho khohlahala, ka hona li lelefatsa bophelo ba ts'ebeletso le ho fokotsa litlhoko tsa tlhokomelo.
Melemo ea Bohlokoa ea Li-brake Linings tsa Winch tse sa amaneng le Asbestos
1. Polokeho e Ntlafalitsoeng
Polokeho ke ea bohlokoa haholo ts'ebetsong ea likepe. Lithapo tsa brake tse seng tsa asbestos li fana ka ts'ebetso e tšepahalang ea brake, li fokotsa kotsi ea ho hloleha ka tšohanyetso kapa ho lokolloa ha mohala o sa laoleheng. Litšobotsi tsa tsona tse tsitsitseng tsa khohlano li tiisa ts'ebetso e ka boleloang esale pele maemong 'ohle.
2. Ho Latela Tikoloho
Lisebelisoa tse seng tsa asbestos li latela melao ea machaba e kang:
1. Litumellano tsa IMO mabapi le polokeho ea likepe le ho sebelisa hape
2. Litekanyetso tsa ISO bakeng sa polokeho ea thepa
3. Litlhoko tsa SOLAS
Sena se ba beha e le khetho e tsitsitseng bakeng sa beng ba likepe ba batlang ho latela melao ea lefats'e ea tikoloho le polokeho.
3. Ho tšoarella ho Phahameng
Ka lebaka la sebopeho sa tsona se kopaneng, masela a sa sebeliseng asbestos a fana ka:
1. Ho hanyetsa mocheso haholo
2. Botšepehi bo matla ba mechini
3. Sekhahla se tlase sa ho robeha
Sena se fella ka bophelo bo bolelele ba tšebeletso le ho fokotsa litšenyehelo tsa ho nkela sebaka.
4. Ho Feto-fetoha ha Litšebeliso ho pholletsa le Likopo
Leha e sebelisoa haholo-holo ho hokela li-winches le likhalase tsa moea, li-lining tsa brake tse seng tsa asbestos le tsona li loketse:
1. Likereine le li-hoist
2. Lithulusi tsa ho cheka
3. Mechini ea indasteri
4. Lifti le lisebelisoa tsa merafo
Ho ikamahanya le maemo hona ho totobatsa ho tšepahala ha tsona ho pholletsa le mefuta e fapaneng ea lits'ebetso tse boima.
5. Ho lumellana le Libaka tse 'maloa
Lithapo tsa brake tse seng tsa asbestos li sebetsa hantle ka thepa e tloaelehileng joalo ka tšepe e entsoeng ka tšepe le tšepe. Bakeng sa ts'ebetso e ntle ka ho fetisisa, ho eletsoa ho sebelisa libaka tse thatafalitsoeng tsa Brinell tse 180 kapa ho feta.
6. Tenyetsehang Saese le Tsamaiso e Bonolo
Masela ana a fumaneha ka mefuta e mengata ea botenya (5mm–30mm), bophara (30mm–550mm), le bolelele ba meqolo, e leng se lumellang ho fetoloa bakeng sa litsamaiso tse fapaneng tsa winch. Li ka boela tsa sebetsoa ka lisebelisoa tse tloaelehileng tsa ho seha, e leng se thusang ho kenya le ho hlokomela ka mokhoa o bonolo.
Mehopolo ea Ts'ebetso
Ho ntlafatsa tshebetso, ho bohlokwa ho sebedisa di-lining tsa brake ka hara meedi e kgothaletswang:
1. Lebelo la ho thella: ka tlase ho 12 m/s
2. Kgatelelo ya bokahodimo: ka tlase ho 200 N/cm²
3. Mocheso: ka har'a mefuta e boletsoeng
Ho feta moo, tshebetso ya kgohlano e ka fapana ho latela hore na sistimi e sebetsa maemong a omileng kapa a qoelitsoeng ka oli, mme kgohlano e fokotsehile e lebelletswe dibakeng tsa oli.
Qetello
Lithapo tsa brake tsa winch tse sa keneng ka har'a asbestos li bontša tsoelo-pele e ikhethang theknolojing ea polokeho ea likepe. Ka ho kopanya botsitso bo phahameng ba khohlano, ho hanyetsa mocheso ka mokhoa o ikhethang, le ho latela melao ea tikoloho, li fana ka tharollo e tšepahalang bakeng sa likepe tsa mehleng ena.
Bakeng sa beng ba likepe le basebetsi, ho tsetela ho li-brake lintlheng tsa boleng bo holimo tse seng tsa asbestos ho feta ho latela melao feela—ke taba ea ho sireletsa basebetsi, thepa le likepe libakeng tse thata tsa leoatle. Ha lekala la likepe le ntse le tsoela pele ho hatela pele, thepa ena e ncha e tla tsoela pele e le karolo ea motheo ea ts'ebetso ea ho emisa likepe ka mokhoa o sireletsehileng le o sebetsang hantle.
