Ka nānā ʻana i nā pahu mālama wai cryogenic
Ka lā: Feb 19, 2020
Ke hana nei ka pahu mālama cryogenic, aia nā pilikia e like me ka leakage, overpressure, a me ka pahū. Inā ʻaʻole ʻike ʻia nā pōʻino huna ma mua o kēia mau pōʻino a mālama ʻia i ka manawa, e ulu ana lākou i nā pōʻino koʻikoʻi. No laila, ʻo ka hoʻokumu ʻana i kahi ʻōnaehana nānā ʻana i ka pahu mālama mālama cryogenic a me ka hoʻokō pono ʻana he mea nui loa ia e hōʻoia i ka hana palekana o nā moku kaomi. ʻO ka nānā ʻana i kēlā me kēia lā o nā pahu mālama e pili ana i kēia:
1. Inā paha ka valve a me ka pipeline o kapahu mālama cryogenice kahe ana, a inā he hau a he hou paha ka pahu.
2. Inā aia nā kiwi a pau o ka pahu waihona i ka wehe maʻamau a pani.
3. Inā paha e hana maʻamau ka mita pahu mālama mālama cryogenic (nā ana pae, ke ana kaomi), a inā pili nā ʻāpana hōʻike DCS me ka mika ma ka pūnaewele.
4. O ke kaomi ma kamoku kaomipahu waihona maʻamau? Ke kokoke a i like paha ke kaomi i ke kaomi kiʻekiʻe, pono e wehe ʻia ka valve vent e hoʻokuʻu i ke kaomi.
5. Inā ʻoi aku ka nui o ka hoʻopiha wai o ka pahu mālama i ka 95%.
6. No ke kaomi maʻamau ka pauda insulation tank, he mea maʻamau ke kinoea hoʻopaʻa? (50mmH2O)
7. Ua kapu loa ia e waiho i na mea puhi a pahū a me na mea a pau kokoke i kapahu waihona wai oxygen.
8. Ua pāpā loa ʻia ke ahi ma kahi kokoke i ka pahu mālama wai cryogenic oxygen.
9. E ho'āʻo i ka maʻiʻo o ka acetylene a me ka huina hydrocarbons i loko o ka oxygen wai o ka pahu mālama i hoʻokahi manawa i ka pule. ʻAʻole pono ka ʻike o ka acetylene ma mua o 0.1 × 10-6 (v \/ v). Ke ʻoi aku ka nui, pono e hoʻokuʻu ʻia ka oxygen wai i ka manawa no ka mālama hou ʻana.
10. Inā paha i hoʻokumu maikaʻi ʻia ka pahu mālama cryogenic.
11. Ināʻaʻole hoʻohanaʻia no ka manawa lōʻihi, pono e hōʻoia i ka nui o ka wai i loko o ka pahu waihona, iʻole e hoʻomaha hou i ka pahu pani a lōʻihi ka manawa.
12. Ina paha ua poino na wawae o ka pahu hoahu cryogenic, ina paha e poho ana ke kumu, kulou, a nahaha paha, ina paha ua paa na bolt paa, a ina paha ua deformed ka pahu.
13. E nānā mau i ka momi o ka pahu waihona.
1. Inā paha ka valve a me ka pipeline o kapahu mālama cryogenice kahe ana, a inā he hau a he hou paha ka pahu.
2. Inā aia nā kiwi a pau o ka pahu waihona i ka wehe maʻamau a pani.
3. Inā paha e hana maʻamau ka mita pahu mālama mālama cryogenic (nā ana pae, ke ana kaomi), a inā pili nā ʻāpana hōʻike DCS me ka mika ma ka pūnaewele.
4. O ke kaomi ma kamoku kaomipahu waihona maʻamau? Ke kokoke a i like paha ke kaomi i ke kaomi kiʻekiʻe, pono e wehe ʻia ka valve vent e hoʻokuʻu i ke kaomi.
5. Inā ʻoi aku ka nui o ka hoʻopiha wai o ka pahu mālama i ka 95%.
6. No ke kaomi maʻamau ka pauda insulation tank, he mea maʻamau ke kinoea hoʻopaʻa? (50mmH2O)
7. Ua kapu loa ia e waiho i na mea puhi a pahū a me na mea a pau kokoke i kapahu waihona wai oxygen.
9. E ho'āʻo i ka maʻiʻo o ka acetylene a me ka huina hydrocarbons i loko o ka oxygen wai o ka pahu mālama i hoʻokahi manawa i ka pule. ʻAʻole pono ka ʻike o ka acetylene ma mua o 0.1 × 10-6 (v \/ v). Ke ʻoi aku ka nui, pono e hoʻokuʻu ʻia ka oxygen wai i ka manawa no ka mālama hou ʻana.
10. Inā paha i hoʻokumu maikaʻi ʻia ka pahu mālama cryogenic.
11. Ināʻaʻole hoʻohanaʻia no ka manawa lōʻihi, pono e hōʻoia i ka nui o ka wai i loko o ka pahu waihona, iʻole e hoʻomaha hou i ka pahu pani a lōʻihi ka manawa.
12. Ina paha ua poino na wawae o ka pahu hoahu cryogenic, ina paha e poho ana ke kumu, kulou, a nahaha paha, ina paha ua paa na bolt paa, a ina paha ua deformed ka pahu.
13. E nānā mau i ka momi o ka pahu waihona.
ʻatikala hope loa:
E hoʻouna i kāu nīnau
ʻAʻole mākou e hāʻawi wale i kahi huahana maikaʻi, akā hāʻawi pū kekahi i ka lawelawe kiʻekiʻe. Inā makemake ʻoe i kā mākou huahana,
hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou ma kēia mau ala.
hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou ma kēia mau ala.
