ʻO ka wili electromagnetic kūikawā no ka hoʻoheheʻe ʻana i ka ea DHF

Kaʻana ʻike kumu o ka coil valve solenoid

1. kumu o ka hana

Ua ʻike mākou hiki ke hoʻokaʻawale ʻia nā valve solenoid i nā ʻano he nui e like me kā lākou hana a me kā lākou hana.Hoʻohana kekahi i ka wai a hana kekahi i ke kinoea, akā ʻo ka hapa nui o nā pahu solenoid i uhi ʻia ma ke kino valve, no laila hiki ke hoʻokaʻawale ʻia nā mea ʻelua.ʻO ka mea maʻamau, hana ʻia kāna kumu valve e nā mea ferromagnetic.Ke hoʻoikaika ʻia ka coil, e huki ka mana magnetic i ke kumu o ka valve, a na ke kumu valve e pana i ka valve e hoʻopau i ka wehe a me ka pani ʻana.

2. Ke kumu o ke kuni

I ka wā e hana ana ka coil valve solenoid, e huki ʻia ke kumu hao, a laila e hana ia i kahi kaapuni magnetic paʻa.Aia ka inductance i kahi kūlana nui, e alakaʻi maoli ia i ka wela.Ke kiʻekiʻe ka wela, ʻaʻole hiki ke huki ʻia ke kumu hao i ka wā e hoʻoikaika ʻia ai, no laila e hoʻemi ʻia ka inductance a me ka impedance o ka coil a piʻi aʻe ke ʻano, e hoʻonui ai i ka nui o ke au.I kēia manawa, ʻo ka haumia aila, nā haumia a me ka deformation e hoʻopilikia i ka hana o ke kumu hao.Ke hoʻoikaika ʻia, e hana mālie a ʻaʻole hiki ke huki.

3. He aha ka pili o ka mana magnetic me ka nui?

ʻO ka ʻōlelo maʻamau, pili ka nui o ka ikaika magnetic o ka coil valve solenoid i ka helu o nā huli, ke anawaena uea a me ka wahi permeability magnetic o ke kila magnetic.Hiki ke hoʻokaʻawale i kēia manawa i ka DC a me ke kamaʻilio, kahi e hiki ai ke huki ʻia ka DC solenoid valve coil mai ke kumu hao, akā ʻaʻole hiki i ke kelepona kamaʻilio ke hana i kēia.I ka manawa e ʻike ai ka puʻupuʻu kamaʻilio e hana ana ka coil i kēia, e hoʻonui ʻia ke au i loko o ka coil, no ka mea he apo pōkole kona i loko.

4. ʻO ke ʻano hoʻokae maikaʻi a maikaʻi ʻole paha

Inā makemake mākou e hoʻokolokolo inā maikaʻi a maikaʻi ʻole paha ka coil valve solenoid, hiki iā mākou ke hoʻohana i ka multimeter e ana i ke kūʻē o ka valve solenoid.No ka wili maikaʻi, pono ke kū'ē ma kahi o 1K ohms.Inā ana ʻia, ʻike ʻia he palena ʻole a kokoke paha ke kūʻē i ka zero, e hōʻike ana he pōkole pōkole i kēia manawa a ʻaʻole hiki ke hoʻohana hou ʻia.
