ʻO ka ʻaila-a-gasoline resistant hose: hilinaʻi "nā kīʻaha koko" o ke kaʻa

Paʻa ʻaila-a-gasolineʻO ka hose (MBS hose, MBS hose) he paipu maʻalahi i hoʻolālā ʻia e hoʻolako (hoʻolako, pump) ka ʻaila, ka wahie diesel, nā aila, nā wai hoʻoheheʻe a me nā huahana ʻaila ʻē aʻe, a me nā mea hoʻoheheʻe, nā ʻawaʻawa nāwaliwali a me nā mea hoʻolaha ikaika ikaika ʻē aʻe.

Hoʻohana ʻia nā hoses MBS no ka hoʻopili hermetic o nā ʻāpana i ka wahie, ka aila, ka haki a me nā ʻōnaehana ʻē aʻe o nā kaʻa, i nā ʻōnaehana hydraulic o nā mea hana haʻahaʻa a me ke kiʻekiʻe, no ka hoʻoulu ʻana i nā huahana petroleum ma waena o nā pahu a me nā mea like ʻole, a me nā mea ʻē aʻe. e ʻae i ka neʻe ʻana o nā ʻāpana ʻōnaehana e pili ana i kekahi i kekahi, pale maikaʻi lākou i nā deformations a me nā hopena maikaʻi ʻole.ʻO kēia mau mea i alakaʻi i ka hoʻohana nui ʻana o nā hoses MBS i nā lālā like ʻole o ka ʻenehana, ʻoihana, etc.

 

Nā ʻano a me nā ʻano o nā hoses MBS

Hoʻokaʻawale ʻia nā hose MBS (hoses) e like me ka mea nui o ka hana ʻana, ke kumu a me ka hoʻopili ʻana, a me nā ʻano.

E like me ka mea o ka hana ʻana, ʻo nā hoses:

• ʻO Rubber - nā ʻāpana o loko a me waho o ka hose (mau lima) i hana ʻia i nā ʻano lāʻau like ʻole i kū i kekahi mau wai a me nā kinoea;
• PVC - ua hana ʻia ka hose i nā ʻano like ʻole o ka polyvinyl chloride a me nā polymers ʻē aʻe e kūʻē i nā ʻano ʻino like ʻole.

Wahi a ke kumu, ua māhele ʻia nā hoses MBS i ʻekolu pūʻulu:

• Paʻi - i hoʻolālā ʻia e hana ma lalo o ka piʻi ʻana o ke kaomi (mai ka lewa a ma luna), ua lawe ʻia nā ana i kā lākou hoʻolālā e pale ai i nā deformations a me nā haki ʻana o nā paia e ka wai i hoʻokomo ʻia;
• Suction - i hoʻolālā ʻia e hana ma lalo o ke kaomi hoʻemi ʻia (ma lalo o ka lewa), ua lawe ʻia nā ana i loko o kā lākou hoʻolālā e pale ai i ka hoʻopiʻi ʻana o nā paia ma lalo o ka hana o ka ʻōpala (e mālama mau i ka ʻāpana kūloko kūloko);
• Pumi-huki honua.

E like me ka hoʻohana ʻana, hiki ke hoʻokaʻawale ʻia nā hoses i kekahi mau pūʻulu:

• No ka hoʻohana ʻana i ke ola o kēlā me kēia lā, nā hale kūʻai hoʻoponopono kaʻa a me nā kūlana ʻē aʻe me ka hoʻokomo ʻole ʻana i ka paipu i loko o nā kaʻa a i ʻole nā ​​​​mea hana ʻē aʻe;
• No nā ʻōnaehana wahie kaʻa;
• No nā ʻōnaehana braking o nā kaʻa me ka hoʻohana ʻana i ka wai hana ma muli o ka mineral a me ka aila synthetic;
• No nā'ōnaehana hydraulic o nā kaʻa, nā mīkini kaʻa, nā mīkini mahiʻai, nāʻoihana a me nā mea hana'ē aʻe;
• No ka hoʻopiha ʻana i nā mea hana (no ka puhi ʻana i nā wahie a me nā aila, hoʻolako i nā wahie i ka mea kūʻai aku, etc.).

ʻO ka hope, ua māhele ʻia nā hoses i ʻelua ʻano e pili ana i ka uila static:

• Nā paipu maʻamau;
• Nā paipu i hoʻopaʻa ʻia e hoʻohuli i ka uila paʻa.

I ka hoʻolālā ʻana o nā hoses o ke ʻano ʻelua, hāʻawi ʻia kahi kaula keleawe, kahi e pāʻani ai i ke ʻano o ka grounding.Hoʻohana ʻia kēia mau hose MBS ma nā mīkini hoʻopihapiha a me nā mea hana, ma nā mea hana ʻoihana, etc.

ʻO nā hiʻohiʻona o nā pale SBS, pono e hoʻomaopopo ʻia:

• Ke kaomi hana - no ka suction - 0.09 MPa (0.9 atmospheres), no ka hoʻokuʻuʻana - ka laulā maʻamau o 0.1, 0.16, 0.25, 0.4, 0.63, 1.0, 1.6, 2.5, 4, 6.3 a me 10 MPa (mai ka 1 a hiki i ka 100) ;
• Ke anawaena o loko - mai ka 3 a hiki i ka 25 mm (pahu PVC) a mai ka 4 a hiki i ka 100 mm (hoses rubber);
• Ke anawaena o waho - e pili ana i ka mānoanoa o nā paia, ke ʻano o ka braid, ke alo o ka hoʻoikaika ʻana, a me nā mea ʻē aʻe.
• ka pae wela hana.

Ma kahi kaʻawale, pono e ʻōlelo ʻia e pili ana i ka palena hope.I kēia lā, hana ʻia nā hose MBS no ʻekolu mau ʻāpana climatic, ʻokoʻa lākou i nā mahana maikaʻi ʻole i ʻae ʻia:

• No nā piʻi wela - a hiki i -35 ° C;
• No nā piʻi wela - a hiki i -20 ° C;
• No ke anu anuanu - a hiki i -50 ° C.

ʻO ka mahana maikaʻi loa no nā paipu a pau he like ia - a hiki i + 70 ° C no nā wahie (gasoline, kerosene, diesel fuel) a hiki i + 100 ° C no nā aila.
