chii chinonzi DOT chiyero chelpg silinda?

DOT inomirira Dhipatimendi Rezvekutakurwa muUnited States, uye inoreva seti yemirau nezviyero zvinotonga dhizaini, kuvaka, uye kuongororwa kwezvinhu zvakasiyana-siyana zvine chekuita nekufambisa, kusanganisira masilinda eLPG. Kana tichitaura nezve silinda yeLPG, DOT inowanzoenderana nemirairo yeDOT inoshanda kumasilinda anoshandiswa kuchengeta kana kutakura liquefied petroleum gas (LPG).

Heano kuparara kwebasa reDOT zvine chekuita neLPG masilinda:

1. DOT Zvinyorwa zveCylinders
Iyo DOT inoisa zviyero zvekugadzira, kuyedza, uye kunyora mazita emasilinda anoshandiswa kuchengetedza zvinhu zvine njodzi, kusanganisira LPG. Iyi mirairo inonyanya kuitirwa kuve nechokwadi chekuchengetedza panguva yekutakura uye kubata magasi cylinders.

DOT-Atenderwa Masilinda: LPG masilinda akagadzirirwa kushandiswa uye kutakura muUS anofanirwa kusangana neDOT zvakatemwa. Masilinda aya anogarodhindwa nemabhii “DOT” achiteverwa nenhamba chaiyo inoratidza mhando uye mwero wecylinder. Semuenzaniso, silinda yeDOT-3AA chiyero chemasilinda esimbi anoshandiswa kuchengetedza magasi akamanikidzwa seLPG.
2. DOT Cylinder Marking
Silinda yega yega DOT-inotenderwa ichange iine mamarks akadhindwa musimbi inopa ruzivo rwakakosha nezve mataurirwo ayo, kusanganisira:

DOT Nhamba: Izvi zvinoratidza iyo chaiyo mhando yehumburumbira uye kutevedzera kwayo neDOT zviyero (semuenzaniso, DOT-3AA, DOT-4BA, DOT-3AL).
Nhamba Yeseri: Silinda yega yega ine yakasarudzika identifier.
Manufacture's Mark: Zita kana kodhi yemugadziri akagadzira silinda.
Zuva Rokuedzwa: Masilinda anofanirwa kugara achiedzwa kuti achengetedzeke. Chitambi chicharatidza zuva rekupedzisira rekuyedza uye zuva rekuyedza rinotevera (kazhinji makore ese 5-12, zvichienderana nerudzi rwehumburumbira).
Pressure Rating: Iyo yakanyanya kumanikidza iyo silinda yakagadzirirwa kushanda zvakachengeteka.
3. DOT Cylinder Standards
Mitemo yeDOT inovimbisa kuti masilinda anovakwa kuti amire zvakachengeteka kumanikidza. Izvi zvinonyanya kukosha kuLPG, iyo inochengetwa semvura iri pasi pekumanikidzwa mukati memasilinda. DOT zviyero zvinofukidza:

Material: Macylinders anofanirwa kugadzirwa kubva kune akasimba zvakakwana kuti amire kumanikidza kwegasi mukati, sesimbi kana aluminium.
Ukobvu: Ukobvu hwemadziro esimbi hunofanira kusangana nezvinodiwa zvekusimba uye kusimba.
Mhando dzevhavha: Ivhavhavhavha yevhavha inofanira kuenderana neDOT zvinyorwa kuti ive nechokwadi chekubata uye kuchengeteka kana silinda yakabatanidzwa kune midziyo kana kushandiswa pakufambisa.
4. Kuongorora uye Kuedzwa
Kuedzwa kweHydrostatic: DOT inoda kuti masilinda ese eLPG aedze hydrostatic bvunzo yega yega makore mashanu kana gumi (zvichienderana nerudzi rwehumburumbira). Muedzo uyu unosanganisira kuzadza silinda nemvura nekuidzvanya kuti ive nechokwadi chekuti inogona kubata gasi zvakachengeteka pakumanikidza kunodiwa.
Kuongorora Kwekuona: Macylinders anofanirwawo kutariswa nemaziso kuona kukuvara kwakadai se ngura, dents, kana makatsemuka asati aiswa pabasa.
5. DOT vs. Mimwe Mitemo Yepasi Pose
Nepo mirau yeDOT ichinyatsoshanda kuUS, dzimwe nyika dzine zvadzo zviyero zvemasilinda egasi. Semuyenzaniso:

ISO (International Organisation for Standardization): Nyika zhinji, kunyanya muEurope neAfrica, dzinotevera zviyero zveISO zvekugadzira uye kutakura masilinda egasi, akafanana neDOT zviyero asi anogona kunge aine misiyano yedunhu.
TPED (Transportable Pressure Equipment Directive): MuEuropean Union, TPED inotonga zviyero zvekutakura midziyo yekumanikidza, kusanganisira LPG silinda.
6. Kufunga nezvekuchengetedza
Kubata Kwakakodzera: Mitemo yeDOT inovimbisa kuti masilinda akagadzirirwa kubata zvakachengeteka, kuderedza njodzi dzetsaona panguva yekufambisa kana kushandiswa.
Emergency Relief Mavharuvhu: Masilinda anofanirwa kuve neakachengeteka mavharuvhu ekuyamura mavharuvhu kudzivirira njodzi pamusoro-kudzvinyirira.
Muchidimbu:
DOT (Dhipatimendi Rezvekutakurwa) mirau inovimbisa kuti masilinda eLPG anoshandiswa muUS anosangana nemhando yepamusoro yekuchengetedza uye kusimba. Mitemo iyi inotonga kuvakwa, kunyora mazita, kuongororwa, uye kuyedzwa kwemasilinda egasi kuona kuti anogona kuve negasi rakamanikidzwa zvakachengeteka pasina kukundikana. Aya mazinga anobatsirawo kutungamira vanogadzira uye vanogovera mukugadzira uye kugovera akachengeteka, akavimbika masilinda evatengi.

Kana iwe ukaona DOT ichimaka paLPG silinda, zvinoreva kuti silinda yakavakwa uye yakaedzwa zvinoenderana nemirairo iyi.
