Hose ya kulehemu

Je, ni vipengele gani muhimu vya kuzingatia wakati wa kuchagua hose ya kulehemu?

Wakati wa kuchagua hose ya kulehemu, vipengele kadhaa muhimu vinahitajika kuzingatiwa ili kuhakikisha kuwa inafaa kwa maombi maalum ya kulehemu. Moja ya mambo muhimu zaidi ni nyenzo za hose, kwani inahitaji kudumu na kupinga joto, abrasion, na yatokanayo na kemikali. Hoses nyingi za kulehemu zinafanywa kutoka kwa mpira au vifaa vya thermoplastic, ambayo hutoa kubadilika na upinzani wa kuvaa na kubomoa wakati wa kudumisha uadilifu wao chini ya hali ya juu ya joto. Hose inapaswa pia kuwa na uwezo wa kushughulikia shinikizo la juu, kwani gesi za kulehemu mara nyingi huhifadhiwa na kusafirishwa chini ya shinikizo kubwa. Ni muhimu kuchagua hose yenye ukadiriaji unaofaa wa shinikizo ili kuzuia kupasuka au kushindwa wakati wa matumizi. Zaidi ya hayo, hoses za kulehemu kwa kawaida hutengenezwa kwa mistari miwili tofauti-moja kwa oksijeni na nyingine kwa gesi ya mafuta-kuhakikisha kwamba gesi zinabaki tofauti na hazichanganyiki, ambayo inaweza kusababisha hali ya hatari. Kifuniko cha nje cha bomba pia kinapaswa kuwa sugu kwa sababu za nje kama vile abrasion, miale ya UV, na hali ya hewa, kwani bomba za kulehemu hutumiwa mara nyingi katika mazingira ya nje. Urefu na kipenyo cha hose inapaswa kuchaguliwa kulingana na mahitaji ya mchakato wa kulehemu na umbali kati ya chanzo cha gesi na tovuti ya kulehemu. Zaidi ya hayo, utangamano na aina maalum za gesi zinazotumiwa ni muhimu. Kwa mfano, bomba zinazotumika kwa huduma ya oksijeni lazima zikadiriwe kwa ajili ya matumizi na oksijeni na zisiwe na nyenzo zozote zinazoweza kuathiriwa na oksijeni, kama vile mafuta au grisi. Hatimaye, ni muhimu kuangalia kama kuna vyeti vya sekta yoyote au kufuata viwango vya usalama, kama vile kutoka kwa OSHA au Shirika la Kitaifa la Kulinda Moto (NFPA), ili kuhakikisha kuwa bomba linatimiza vigezo vinavyohitajika vya usalama kwa ajili ya maombi ya kulehemu.

Hozi za kulehemu zinapaswa kudumishwa na kuhifadhiwaje ili kuhakikisha usalama?

Utunzaji sahihi na uhifadhi wa hoses za kulehemu ni muhimu ili kuhakikisha usalama na maisha marefu wakati wa matumizi. Ukaguzi wa mara kwa mara wa hosi unapaswa kufanywa ili kuangalia dalili za uchakavu, kama vile kupunguzwa, michubuko, nyufa, au uvujaji, hasa karibu na vifaa au mahali ambapo hose inagusana na vitu vyenye ncha kali au nyuso zisizo na usawa. Hoses za kulehemu za mpira, aina maarufu kwenye soko, pia zinakabiliwa na hundi hizi.

Ikiwa uharibifu wowote unapatikana kwenye hose ya kulehemu, inapaswa kubadilishwa mara moja ili kuepuka hatari zinazoweza kutokea. Ili kuzuia kushindwa kwa hose, hakikisha kwamba hose inatumiwa ndani ya shinikizo na viwango vya joto vilivyowekwa, kwani kuzidi vigezo hivi kunaweza kusababisha kupasuka. Baada ya kila matumizi, ni muhimu kuhifadhi vyema bomba za kulehemu, iwe zinatoka kwa mtengenezaji maarufu wa hose za kulehemu au la, katika eneo safi, kavu, mbali na jua moja kwa moja, halijoto kali au kemikali zinazoweza kuharibu nyenzo.

Mbinu za kulehemu za hose wakati mwingine zinaweza kuathiri uaminifu wa hose, kwa hiyo ni muhimu kulipa kipaumbele kwa vipengele hivi wakati wa ukaguzi. Kukunja bomba bila kulegea ni muhimu ili kuzuia mikunjo au mikunjo, kwani mikunjo mikali inaweza kudhoofisha bomba na kupunguza muda wake wa kuishi. Wakati wa kuhifadhi mabomba ya kulehemu, hakikisha kuwa yamening'inia au yamelazwa badala ya kuviringishwa kwa nguvu sana.

Kwa kuongeza, hose ya kulehemu inapaswa kuwekwa bila uchafu, hasa mafuta, mafuta, au vitu vingine vinavyoweza kuguswa na gesi zinazohamishwa, hasa katika mabomba ya oksijeni, ambapo hata kiasi kidogo cha uchafuzi kinaweza kuunda hali ya hatari. Ikiwa hose ya kulehemu inakabiliwa na matumizi ya kazi nzito au mazingira magumu, kusafisha na matengenezo ya mara kwa mara inapaswa kufanywa ili kuondoa mkusanyiko wowote wa uchafu.

Kabla ya kila matumizi, ni muhimu kuangalia fittings zote na viunganisho vya hose ya kulehemu ili kuhakikisha kuwa imefungwa kwa usalama na haina uvujaji. Kutumia reli za hose au ndoano za kuhifadhi kunaweza pia kusaidia kupanga bomba na kuzuia uharibifu kutoka kwa kugongana au mikwaruzo. Kwa kufuata mazoea haya ya matengenezo na uhifadhi, hoses za kulehemu zitadumisha usalama wao, kuegemea, na utendaji, kuhakikisha mazingira salama ya kufanya kazi kwa waendeshaji.

Twin-line Structure and Safety Design Principles: Welding Hoses

SINOPULSE revolutionizes industrial safety through the engineering of twin welding hoses with a cutting-edge dual-chamber structure. Engineered for precision and reliability, our rubber twin welding hoses address the critical need for safe gas separation in high-risk welding and cutting operations, setting a new standard for performance and protection.

At the heart of SINOPULSE’s welding hoses lies a dual-channel architecture, featuring independent inner tubes dedicated to oxygen and combustible gases such as acetylene or propane. This physical separation is not merely a design choice but a safety imperative: by preventing the mixing of explosive gas combinations, it eliminates the risk of catastrophic ignition within the hose itself. The oxygen chamber, constructed from premium rubber compounds, adheres to strict non-oil and non-grease standards, ensuring compliance with oxygen service safety protocols.
