DOT e emetse Lefapha la Lipalangoang United States, 'me e bolela letoto la melao le litekanyetso tse laolang meralo, kaho le tlhahlobo ea lisebelisoa tse fapaneng tse amanang le lipalangoang, ho kenyeletsoa le lisilindara tsa LPG. Ha ho buuoa ka moqomo oa LPG, DOT hangata e amana le melaoana ea DOT e sebetsang ho lisilindara tse sebelisetsoang ho boloka kapa ho tsamaisa khase ea petroleum (LPG).
Mona ke karohano ea karolo ea DOT mabapi le li-cylinders tsa LPG:
1. Litlhaloso tsa DOT bakeng sa Li-cylinders
DOT e beha litekanyetso tsa ho etsa, ho lekola, le ho ngola li-cylinders tse sebelisetsoang ho boloka thepa e kotsi, ho kenyeletsoa le LPG. Melao ena e reretsoe haholo-holo ho netefatsa tšireletseho nakong ea ho tsamaisa le ho sebetsana le li-cylinders tsa khase.
Li-cylinders tse Amoheletsoeng ke DOT: Li-cylinders tsa LPG tse etselitsoeng ho sebelisoa le ho tsamaisoa naheng ea US li tlameha ho kopana le lintlha tsa DOT. Hangata lisilindara tsena li hatisoa ka litlhaku tse reng “DOT” li lateloa ke nomoro e itseng e bontšang mofuta le maemo a silindara. Ka mohlala, cylinder ea DOT-3AA ke tekanyetso ea li-cylinders tsa tšepe tse sebelisetsoang ho boloka likhase tse hatelitsoeng joaloka LPG.
2. Ho tšoaea ha DOT Cylinder
Silinda e 'ngoe le e' ngoe e amohetsoeng ke DOT e tla ba le matšoao a hatisitsoeng ka har'a tšepe e fanang ka tlhaiso-leseling ea bohlokoa mabapi le litlhaloso tsa eona, ho kenyelletsa:
Nomoro ea DOT: Sena se bontša mofuta o khethehileng oa cylinder le ho lumellana ha eona le litekanyetso tsa DOT (mohlala, DOT-3AA, DOT-4BA, DOT-3AL).
Nomoro ea serial: Silinda e 'ngoe le e' ngoe e na le sekhetho se ikhethileng.
Letšoao la Moetsi: Lebitso kapa khoutu ea moetsi ea entseng silindara.
Letsatsi la Teko: Li-cylinders li tlameha ho lekoa khafetsa bakeng sa polokeho. Setempe se tla bontša letsatsi la ho qetela la teko le letsatsi le latelang la teko (hangata lilemo tse ling le tse ling tse 5-12, ho itšetlehile ka mofuta oa cylinder).
Khatello ea Khatello: Khatello e phahameng ka ho fetisisa eo cylinder e etselitsoeng ho sebetsa ka mokhoa o sireletsehileng.
3. Litekanyetso tsa DOT Cylinder
Melao ea DOT e netefatsa hore li-cylinders li hahoa ho mamella khatello e phahameng ka mokhoa o sireletsehileng. Sena se bohlokoa haholo bakeng sa LPG, e bolokiloeng e le mokelikeli tlas'a khatello ka har'a lisilindara. Litekanyetso tsa DOT li akaretsa:
Boitsebiso: Li-cylinders li tlameha ho etsoa ka thepa e matla ka ho lekaneng ho mamella khatello ea khase ka hare, joaloka tšepe kapa aluminium.
Botenya: Botenya ba marako a tšepe bo tlameha ho finyella litlhoko tse khethehileng bakeng sa matla le ho tšoarella.
Mefuta ea Li-valve: Sephahla sa cylinder se tlameha ho lumellana le litlhaloso tsa DOT ho etsa bonnete ba ho sebetsana hantle le tšireletseho ha cylinder e hokahane le lisebelisoa kapa e sebelisetsoa ho tsamaisa.
4. Tlhahlobo le Teko
Teko ea Hydrostatic: DOT e hloka hore lisilindara tsohle tsa LPG li etse tlhahlobo ea hydrostatic lilemo tse ling le tse ling tse 5 kapa tse 10 (ho latela mofuta oa silindara). Teko ena e kenyelletsa ho tlatsa moqomo ka metsi le ho o hatella ho etsa bonnete ba hore o ka tšoara khase ka mokhoa o sireletsehileng khatellong e hlokahalang.
Litlhahlobo Tse Bonahalang: Li-cylinders le tsona li tlameha ho hlahlobjoa ka mahlo bakeng sa tšenyo e kang mafome, makhopho, kapa mapetsong pele li kenngoa ts'ebetsong.
5. DOT khahlano le Maemo a Mang a Machaba
Le hoja melao ea DOT e sebetsa ka ho khetheha ho US, linaha tse ling li na le litekanyetso tsa tsona tsa li-cylinders tsa khase. Ka mohlala:
ISO (International Organization for Standardization): Linaha tse ngata, haholo-holo tsa Europe le Afrika, li latela litekanyetso tsa ISO bakeng sa ho etsa le ho tsamaisa lisilindara tsa khase, tse tšoanang le tsa DOT empa li ka ba le liphapang tse itseng tsa libaka.
TPED (Transportable Pressure Equipment Directive): Linaheng tsa European Union, TPED e laola litekanyetso tsa ho tsamaisa likepe tsa khatello, ho akarelletsa le li-cylinders tsa LPG.
6. Mehopolo ea Tšireletso
Tšoaro e nepahetseng: Melao ea DOT e netefatsa hore li-cylinders li etselitsoe ho tšoaroa ka mokhoa o sireletsehileng, ho fokotsa kotsi ea likotsi nakong ea lipalangoang kapa tšebeliso.
Li-valve tsa Thuso ea Tšohanyetso: Li-cylinders li tlameha ho ba le likarolo tsa polokeho joalo ka li-valve tsa liphallelo ho thibela khatello e feteletseng ea khatello.
Ka kakaretso:
Melao ea DOT (Lefapha la Lipalangoang) e netefatsa hore lisilindara tsa LPG tse sebelisoang US li finyella litekanyetso tse phahameng tsa polokeho le nako e telele. Melao ena e laola kaho, ho ngola, ho hlahlojoa le ho hlahlojoa ha lisilindara tsa khase ho netefatsa hore li ka ba le khase e hatelitsoeng ka mokhoa o sireletsehileng ntle le ho hloleha. Litekanyetso tsena li boetse li thusa ho tataisa bahlahisi le barekisi ho hlahisa le ho aba lisilindara tse bolokehileng, tse tšepahalang bakeng sa bareki.
Haeba u bona letšoao la DOT holim'a cylinder ea LPG, ho bolela hore cylinder e hahiloe le ho lekoa ho latela melao ena.
