(1) ʻAʻole kūpono ʻole electromagnet
① Ma muli o ka ʻelemakule o ke kumu uwila (kumu) o ka hui plug, ka hoʻopili maikaʻi ʻole a me ke kuʻi ʻana o ke alakaʻi electromagnet, ʻaʻole hiki ke hana 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.

⑤ Hoʻololi ʻia ka lima alakaʻi magnetic ma lalo o ke kaomi hopena, a ʻo ka hui friction i haku ʻia me ka lima alakaʻi magnetic a hoʻohana ʻia ka lima lima i ka wā e hoʻohana ai, e hopena i ka hoʻonui ʻana i ka ikaika hysteresis o ka valve proportional.

⑥ Ua hewa ka mea hoʻonui proportional, no laila ʻaʻole hana ka electromagnet proportional. I kēia manawa, pono e nānā ʻia nā ʻāpana like ʻole o ke kaapuni amplifier e hoʻopau i ka hewa o ka pōʻai hoʻonui proportional.

7 Ua haki ʻia ka pilina ma waena o ka mea hoʻonui proportional a me ka electromagnet a i ʻole ua hemo ka pahu amplifier, i ʻole e hana ka electromagnet proportional. I kēia manawa, pono e pani ʻia ka laina haʻihaʻi a hoʻopili paʻa.
