(1) ʻO ka hewa electromagnet proportional ① Ma muli o ke kumu o ka hoʻohui ʻana i ka uwila (kumu) ka ʻelemakule, ka hoʻopili maikaʻi ʻole a me ka hoʻopili ʻana i ke alakaʻi electromagnet a me nā kumu ʻē aʻe, ka hopena i hiki ʻole ke hana i ka electromagnet proportional (ʻaʻole hiki ke hele i kēia manawa). I kēia manawa, hiki ke hoʻohana ʻia ka mita e ʻike ai, inā ʻike ʻia ke kūpaʻa ʻole ʻia, hiki iā ʻoe ke wili hou i ke alakaʻi, hoʻoponopono i ke kumu a hoʻopili paʻa i ke kumu. (2) ʻO ka hāʻule ʻole o nā ʻāpana coil e pili ana i ka wā kahiko o ka coil, ka ʻā ʻana o ka coil, ka haki ʻana o ka uea kūloko a me ka piʻi ʻana o ka wela o ka coil. ʻAʻole lawa ka piʻi ʻana o ka mahana o ka coil i mea e lawa ʻole ai ka mana o ka electromagnet proportional, a ʻo ke koena e hana i ka electromagnet proportional ʻaʻole hiki ke hana. No ka nui loa o ka piʻi ʻana o ka mahana o ka coil, hiki iā ʻoe ke nānā inā ʻoi aku ka nui o kēia manawa, inā ʻilihune ka coil enamled wire insulation, inā paʻa ke kumu valve ma muli o ka lepo, a me nā mea ʻē aʻe, e ʻike i ke kumu. e hoopau; No ka uwea haki, puhi ʻia a me nā mea ʻē aʻe, pono e hoʻololi ʻia ka coil. ʻO ka hewa nui o ka hui armature ʻo ia ka armature a me ka friction pai i hoʻokumu ʻia e ka lima alakaʻi magnetic i ka wā e hoʻohana ai, e hopena i ka hoʻonui ʻana i ka ikaika hysteresis o ka valve. Aia no hoi ka pahu alakai kookoo a me ka armature okoa naʻau, e no hoi kumu i ka mahuahua o ka ikaika hysteresis, pono e waiho. ④ No ka mea, ʻaʻole ikaika ka kuʻi ʻana, a i ʻole ua haki ke kuʻi ʻana o ka lima alakaʻi magnetic ma lalo o ka hana o ka puʻuwai puʻupuʻu puʻupuʻu proportional i hoʻohana ʻia, no laila e nalowale ka electromagnet proportional i kāna hana.
