Electromagnetic valve coil no nā ʻāpana excavator XGMA 815

He aha ke kumu o ka corrosion coil electromagnetic

1. ʻO nā pahu uila electromagnetic kiʻekiʻe e kahe ana ma muli o ka hoʻopaʻa maikaʻi ʻole ʻana, a ʻo ka corrosion o nā terminals e noho nei i ka pae maikaʻi, ʻoiai ʻo ka electrode maikaʻi ʻole.

2.No laila, hiki ke hoʻoholo ʻia ʻo ka hoʻopaʻa maikaʻi ʻole ʻana o ka solenoid valve coil a me ka seepage wai ke kumu nui o ka corrosion o ka pahu. Eia naʻe, ma muli o nā kūlana hana koʻikoʻi ma kahi, he paʻakikī ke pale aku i ka hopena o ka lanahu ma ka coil, no laila ʻaʻohe mea e hōʻoiaʻiʻo ʻaʻohe wai ma ka pahu coil.

3. Ma muli o ka noho ʻana o ka paʻakai ma ka pahu a me ka paʻakai i loko o ka wai, hana ia ma ke ʻano he hopena electrolyte;

4.No laila, hōʻike ʻia ka hopena galvanic.

5.E pili ana i ka pole maikaʻi ʻole, i ke kaʻina hana o ka hoʻopili ʻana i ka coil electromagnetic pani, ua kahe ka nui o nā mea uila i loko o ka pole maikaʻi ʻole, a hāʻule ka corrosion i kēia manawa ma ka ʻili o ka terminal maikaʻi ʻole a kokoke i ka ʻole. , ka mea i inhibits i ka hopena maoli o ka terminal losing electrons, a laila ka corrosion o ka terminal mea inevitable.

6. Ua kapa ʻia kēia i ka pale cathodic pipeline me nā manawa hou.

7. No ka pae maikaʻi, ʻo ke kūlana ke kū'ē, a lilo ia i mea hoʻolaʻa anodic oxidation i ka "Cathodic Protection Law of Pipeline at the Sacrifice of Anodic Oxidation".

8. No laila, ʻoiai inā ʻaʻole ʻike ʻia nā ʻano kino o ke keleawe, e ʻino koke ia, a e haki ka pahu, e hopena i kahi pilikia pani.

9.E hoʻohana i ka multimeter e ana i ka pale o ka solenoid valve. Inā loaʻa kahi pale i loko o ka coil, pono ia ma kahi o 100 ohms! Inā hōʻike ka resistor palena ʻole o ka coil ua haki ia, hiki ke electrified ka solenoid valve coil a hiki ke kau ʻia nā huahana hao ma ka relay, no ka mea, he mau mea magnetic ka relay e huki ai i nā huahana hao ma hope o ka hoʻopili ʻia ʻana o ka wili electromagnetic 220 volt. Inā hiki ke omo i ka mea hao, e hōʻike ana i ka maikaʻi o ka wili, a ʻo ka ʻike hope e hōʻike ana ua haki ka wili. ʻO ka pilikia paʻakikī o ka coil valve solenoid, ʻo kāu hana hewa ʻana i ka hana uila a i ʻole ka manawa e alakaʻi ai i ka wela a me ke ahi, ʻoi aku ka maʻamau. A laila, no ka maikaʻi ʻole o ka maikaʻi, ʻaʻole i hoʻopā maikaʻi ʻia ka wahi hoʻohui o ka coil kūkulu hale, a laila pōkole ka wahi pili ma muli o ka haʻalulu pinepine a i ʻole ke kahe o kēia manawa. ʻO ka hopena ma muli o nā huahana āu e hoʻohana ai. Inā ʻaʻole i hoʻopaʻa ʻia a i hoʻopaʻa ʻia paha, hiki ke like me ka coil hoʻololi optical o DC contactor. A i ʻole, e hoʻololi ʻia wale nō.
