Pilot solenoid valve coil kūpono no Doosan excavato

Hoʻolauna huahana

ʻO ka electromagnetic coil kekahi o nā mea maʻamau i hoʻohana ʻia i nā huahana uila, nā mea pono hale a me nā mea hana. Hana nui ia me ka hoʻohana ʻana i ke kumu o ka electromagnetic induction. ʻO kāna mau hiʻohiʻona uila he haʻahaʻa alapine haʻahaʻa a me ke alapine kiʻekiʻe. Ma waena o lākou, i ka wā e hele ai ka hōʻailona kiʻekiʻe ma o ka mea, e hālāwai ia me ke kū'ē nui, kahi mea e paʻakikī ai i ka hōʻailona kiʻekiʻe ke hele aku, aʻo ka haʻahaʻa haʻahaʻa e hālāwai me ka liʻiliʻi o ke kū'ē i ka wā e hele ai i ka mea. no laila hiki ke hele maʻalahi ka hōʻailona haʻahaʻa. ʻO kona kūpaʻa ʻana i ke au pololei ʻaʻole maoli.

o ka poino o ka huahana

Inā kiʻekiʻe ka wela o ke kino valve, e alakaʻi ia i ka piʻi ʻana o ka mahana o ka coil, a ʻo ka coil ponoʻī e hoʻohua i ka wela i ka wā e hana ai. Nui nā kumu o ka pōʻino coil. Pehea e hoʻoholo ai i kona maikaʻi? ʻO ka hoʻoholo o ka coil open circuit a pōkole paha: hiki ke ana ʻia ke kūpaʻa o ke kino valve e ka multimeter, a hiki ke helu ʻia ke kū'ē ma ka hui ʻana i ka mana coil. Inā pau ʻole ke kūʻē ʻana o ka coil, ua haki ke kaʻapuni hāmama, a inā ʻoi aku ke kūpaʻa i ka zero, ua haki ke kaapuni pōkole. E ho'āʻo inā loaʻa ka mana magnetic: hāʻawi maʻamau i ka mana i ka coil, hoʻomākaukau i nā huahana hao, a kau i nā huahana hao ma ke kino valve. Inā hiki ke hoʻopili ʻia nā huahana hao ma hope o ka uila, ʻo ia ka maikaʻi, inā ʻaʻole ia he haki.

Kiʻekiʻe loa ka alapine hana

ʻO ka hana pinepine ʻana e hoʻopōʻino i ka wili, a inā ʻaʻole kūlike ka pauku keʻa o ke kumu hao no ka manawa lōʻihi i ka wā e hana ai, e hōʻino pū ʻia ai ka coil.

ʻAʻole hana ʻino

ʻO nā hewa maʻamau: ʻaʻole hiki ke huki ʻia ka contactor a me ke kumu hao, deformed ka contactor contact, a aia nā mea ʻē ma waena o ka hoʻopili ʻana, ka pūnāwai a me ke kumu hao paʻa a me ka ikaika, ʻo ia mau mea a pau e hiki ai ke hoʻoheheʻe i ka coil. pōʻino a hiki ʻole ke hoʻohana
