I roto i ēhea āhuatanga kāore e tika ana te whakamahi i te mita rere hikohiko?

Ngā mita rere hikohikohe taputapu e ine ana i te rere o ngā wai kawe hiko i runga i te mātāpono o te whakapūngao hikohiko. Kāore i te pai te whakamahi i ēnei i roto i ngā āhuatanga e whai ake nei:

1. Te ine i ngā wai kore-arataki: Ko te kaupapa mahi o ngā mita rere hikohiko e hangai ana ki te whakaputa i te kaha hikohiko whakaoho ina tapahia e ngā wai arataki ngā rārangi kaha aukume i roto i te papa aukume. Nō reira, me whai kawe hiko te wai i inehia. Mena he iti rawa te kawe hiko o te wai i inehia, pērā i te wai parakore, te hinu, te waipiro, me ētahi atu wai kore-arataki, iti rānei te kawe hiko, kāore e taea e te mita rere hikohiko te whakaputa i ngā tohu whakaoho e ranea ana, ka hua ake he ine hē, he kore rānei e taea te ine.
2. He nui ngā matū ferromagnetic, ngā mirumiru rānei kei roto: Ina he nui ngā matū ferromagnetic kei roto i te wai inehia, ka whakararuraru i te papa aukume o te mita rere hikohiko, ā, ka pā ki te tika o te ine. Hei tāpiri, ko te noho mai o te maha o ngā mirumiru i roto i te wai ka pā kino ki te ine. Nā te mea ka kore e ōrite te kawe hiko o te wai nā ngā mirumiru, ā, ka puta hoki i ngā mirumiru te kaha hiko i roto i te papa aukume, ka whakararuraru i te tohu ine, ā, ka puta he hapa nui ki ngā hua ine.
3. Ngā taiao pāmahana teitei me te pēhanga teitei: Ahakoa he rerekē ngā tauira me ngā rauemi o ngā mita rere hikohiko ka taea te urutau ki tētahi awhe pāmahana me te pēhanga, ina tino teitei te pāmahana, ina nui rawa rānei te pēhanga, ka kino pea ngā wāhanga pēnei i ngā pūoko me ngā arai o te mita rere, ka pā ki tōna mahi me te roa o te mahi. I te nuinga o te wā, ko te awhe pāmahana e tika ana mō ngā mita rere hikohiko noa kei te -20°C ki te 120°C, ā, ko te awhe pēhanga kei te 1.0MPa ki te 4.0MPa. I tua atu i tēnei awhe, me whakamahi ngā mita rere hikohiko pāmahana teitei me te pēhanga teitei i hangaia mō tētahi kaupapa motuhake, engari he utu nui aua mita rere.
4. Te ine i te tere rere iti: Ka pāngia te tika o te ine o ngā mita rere hikohiko i ngā tere rere iti. Nā te mea i ngā tere rere iti, he iti te kaha hikohiko i puta mai, ka ngoikore ki ngā tohu pokanoa o waho, ā, ko te taumira o te mita rere ka whakawhāiti pea i te ine tika o ngā tere rere iti. Ko te tikanga whānui kia nui ake te tere rere ine o te mita rere hikohiko i te 0.3m/s kia tika ai te ine.
5. He iti te wāhi tāutanga: Me whakarite kia tika te ine mō ngā mita rere hikohiko. I te nuinga o te wā, me 5-10 ngā wā o te diameter o te paipa te wāhanga paipa tika o runga, ā, me 3-5 ngā wā o te diameter o te paipa o raro. Mena he whaiti te wāhi tāutanga, ā, kāore e taea te whakatutuki i ngā whakaritenga mō ngā wāhanga paipa tika, ka hua ake he tauira rere wai kore pumau, ka pā ki te tika o te ine. I tēnei wā, me whiriwhiri pea ētahi atu mita rere he iti ake ngā whakaritenga mō te wāhi tāutanga.
6. Ngā taiao wiri kaha: I roto i ngā taiao wiri kaha, ka ngāwari te whakararuraru i ngā pūoko o ngā mita rere hikohiko e te wiri, ka hua ake he tohu ine kore pumau, ā, ka pā ki te tika o te ine. Hei tāpiri, ka taea hoki e te wiri kaha mō te wā roa te wetekina me te pakaru o ngā wāhanga o te mita rere, ka whakaiti i tōna pono me tōna roanga mahi. Nō reira, i ngā wāhi he wiri nui, pērā i te tata ki ngā taputapu ahumahi nui, i ngā wāhi rānei e pāngia ana e te rū whenua, me mahi ngā mahi motuhake mō te mimiti wiri ina whakamahia ana ngā mita rere hikohiko. Ki te kore, kāore e tūtohutia kia whakamahia.
