Kodi muyezo wa DOT wa silinda ya lpg ndi chiyani?

DOT imayimira dipatimenti yowona zamayendedwe ku United States, ndipo imatanthawuza mndandanda wa malamulo ndi miyezo yomwe imayang'anira kamangidwe, kamangidwe, ndi kuyendera zida zosiyanasiyana zokhudzana ndi mayendedwe, kuphatikiza masilinda a LPG. Ponena za silinda ya LPG, DOT nthawi zambiri imagwirizana ndi malamulo a DOT omwe amagwira ntchito ku masilinda omwe amagwiritsidwa ntchito posungira kapena kunyamula mpweya wamafuta amafuta (LPG).

Nayi kuwonongeka kwa ntchito ya DOT pokhudzana ndi masilinda a LPG:

1. Kufotokozera kwa DOT kwa Masilinda
DOT imakhazikitsa miyezo yopangira, kuyesa, ndi kulemba zilembo zamasilinda omwe amagwiritsidwa ntchito kusunga zinthu zowopsa, kuphatikiza LPG. Malamulowa amayang'ana makamaka kuonetsetsa chitetezo panthawi yoyendetsa ndikugwira ma silinda a gasi.

Masilinda Ovomerezedwa ndi DOT: Masilinda a LPG omwe adapangidwa kuti azigwiritsidwa ntchito ndi zoyendera ku US akuyenera kukwaniritsa zofunikira za DOT. Masilindalawa nthawi zambiri amadindidwa ndi zilembo “DOT” zotsatiridwa ndi nambala inayake yomwe imasonyeza mtundu ndi muyezo wa silinda. Mwachitsanzo, silinda ya DOT-3AA ndi muyezo wa masilindala achitsulo omwe amagwiritsidwa ntchito kusunga mpweya woponderezedwa ngati LPG.
2. DOT Cylinder Marking
Silinda iliyonse yovomerezedwa ndi DOT imakhala ndi zolembera muzitsulo zomwe zimapereka chidziwitso chofunikira pazambiri zake, kuphatikiza:

Nambala ya DOT: Izi zikuwonetsa mtundu weniweni wa silinda ndi kutsatira kwake miyezo ya DOT (mwachitsanzo, DOT-3AA, DOT-4BA, DOT-3AL).
Nambala ya Seri: Silinda iliyonse imakhala ndi chizindikiritso chapadera.
Chizindikiro cha wopanga: Dzina kapena code ya wopanga yemwe adapanga silinda.
Tsiku Loyesera: Masilinda ayenera kuyesedwa pafupipafupi kuti atetezeke. Sitampu idzawonetsa tsiku lomaliza loyesa ndi tsiku lotsatira (nthawi zambiri zaka 5-12, malingana ndi mtundu wa silinda).
Pressure Rating: Kuthamanga kwakukulu komwe silinda imapangidwira kuti igwire bwino ntchito.
3. Miyezo ya DOT Cylinder
Malamulo a DOT amaonetsetsa kuti masilindala amamangidwa kuti athe kupirira kupsinjika kwakukulu. Izi ndizofunikira makamaka kwa LPG, yomwe imasungidwa ngati madzi pansi pa kukanikiza mkati mwa masilinda. Miyezo ya DOT imaphimba:

Zofunika: Masilinda amayenera kupangidwa kuchokera kuzinthu zomwe zimakhala zolimba kuti zisapirire mphamvu ya mpweya mkati, monga chitsulo kapena aluminiyamu.
Makulidwe: Makulidwe a makoma achitsulo ayenera kukwaniritsa zofunikira zenizeni kuti zikhale zolimba komanso zolimba.
Mitundu ya Valve: Valve ya silinda iyenera kutsata ndondomeko ya DOT kuti iwonetsetse kugwiritsira ntchito moyenera ndi chitetezo pamene silinda imagwirizanitsidwa ndi zipangizo kapena ntchito zoyendera.
4. Kuyendera ndi Kuyesa
Kuyesa kwa Hydrostatic: DOT imafuna kuti masilindala onse a LPG ayesedwe ndi hydrostatic zaka 5 kapena 10 zilizonse (kutengera mtundu wa silinda). Kuyezetsa kumeneku kumaphatikizapo kudzaza silinda ndi madzi ndikuikakamiza kuti iwonetsetse kuti ikhoza kusunga mpweya wokwanira pakufunika kofunikira.
Kuyang'anira Zowoneka: Masilinda ayeneranso kuyang'aniridwa ndi maso kuti awononge ngati dzimbiri, madontho, kapena ming'alu isanagwiritsidwe ntchito.
5. DOT vs. Miyezo Yapadziko Lonse
Ngakhale kuti malamulo a DOT amagwira ntchito makamaka ku US, mayiko ena ali ndi miyezo yawoyawo ya masilinda a gasi. Mwachitsanzo:

ISO (International Organization for Standardization): Mayiko ambiri, makamaka ku Ulaya ndi Africa, amatsatira mfundo za ISO pakupanga ndi kunyamula masilinda a gasi, omwe ali ofanana ndi miyezo ya DOT koma akhoza kukhala ndi kusiyana kwina kulikonse.
TPED (Transportable Pressure Equipment Directive): Mu European Union, TPED imayang'anira miyezo yonyamula zombo zopanikizika, kuphatikiza masilinda a LPG.
6. Kuganizira za Chitetezo
Kugwira Moyenera: Malamulo a DOT amaonetsetsa kuti masilinda apangidwa kuti azigwira bwino, kuchepetsa ngozi zapaulendo kapena kugwiritsa ntchito.
Ma Vavu Othandizira Mwadzidzidzi: Masilinda ayenera kukhala ndi zida zachitetezo monga ma valve opumira kuti apewe kupanikizika koopsa.
Powombetsa mkota:
Malamulo a DOT (Department of Transportation) amaonetsetsa kuti masilinda a LPG omwe amagwiritsidwa ntchito ku US amakwaniritsa miyezo yapamwamba yachitetezo ndi kulimba. Malamulowa amayang'anira kamangidwe, kulemba zilembo, kuyang'anira, ndi kuyesa ma silinda a gasi kuti atsimikizire kuti atha kukhala ndi mpweya wabwino popanda kulephera. Miyezo imeneyi imathandizanso kutsogolera opanga ndi ogulitsa pakupanga ndi kugawa masilinda otetezeka, odalirika kwa ogula.

Ngati muwona chizindikiro cha DOT pa silinda ya LPG, zikutanthauza kuti silinda yamangidwa ndikuyesedwa molingana ndi malamulowa.
