Solenoid Valve Coil no HYUNDAI Excavator R210-5 R220-5

Nā kumu o ka piʻi ʻana o ka wela o ka coil valve solenoid

1. I ka holo ʻana o ke au i ka coil electromagnetic, e wela a piʻi mālie ka mahana. Ma hope o kekahi manawa, ʻo ka hoʻomehana ʻana a me ka dissipation wela i ke kaulike, a hiki i ka mahana i kahi waiwai paʻa. ʻO ka ʻokoʻa ma waena o kēia mahana a me ka wela ambient i kapa ʻia ʻo ka piʻi ʻana o ka mahana.

2. ʻO ka piʻiʻana o ka mahana o ka solenoid valve coil he mea maʻamau. Hoʻoholo ʻia ka piʻi ʻana o ka mahana i ʻae ʻia e ke ʻano insulation o ka coil, a ʻo ka piʻi ʻana o ka wela o ka coil electromagnetic e haʻahaʻa ma mua o ka piʻi ʻana o ka mahana i ʻae ʻia. Hoʻoholo ʻia ka mahana ambient o ka valve solenoid e ke kiʻekiʻe o ka mahana i ʻae ʻia o ke ʻano insulation o ka coil a me ka piʻi ʻana o ka wela o ka solenoid valve coil. Hoʻohana ʻia ka pahu pahu solenoid valve coil wikiwiki i ka insulation B. Inā ʻaʻole ʻoi aku ka kiʻekiʻe o ka mahana ambient ma mua o 60 degere, ʻaʻole pono ka piʻi ʻana o ka mahana o ka solenoid coil ma mua o 70 degere.

3. (Class B insulation type: ʻo ka piʻi ʻana o ka mahana i ʻae ʻia he 90 degere, a ʻo ke kiʻekiʻe i ʻae ʻia ʻo 130 degere). E hoʻohana i ka mika e ana i ke kūpaʻa o ka valve solenoid. ʻO ke kūpaʻa o ka coil ma kahi o 100 ohms! Inā hōʻike ke kūpaʻa pau ʻole o ka coil ua haki ia, hiki iā ʻoe ke electrified i ka solenoid valve coil a kau i nā huahana hao ma ka solenoid valve, no ka mea, he mau mea magnetic ka solenoid valve e huki ai i nā huahana hao ma hope o ka electrifying ka solenoid valve coil. Inā hiki iā ʻoe ke hoʻopaʻa i ka huahana hao, ʻo ia ke ʻano he maikaʻi ka wili, inā ʻaʻole ia e haki ka wili. ʻO ke ala ʻike o ke kaapuni pōkole a i ʻole kaapuni hāmama o solenoid valve coil ʻo ia ke ana ʻana i kāna on-off me ka multimeter mua, a ʻo ke kumu kūʻē e pili ana i ka zero a i ʻole ka palena ʻole, ʻo ia hoʻi he pōkole pōkole a i ʻole kaapuni wehe.

4. Inā he mea maʻamau ke kūpaʻa i ana ʻia, ʻaʻole ia he manaʻo pono e maikaʻi ka coil. Pono ʻoe e ʻimi i kahi screwdriver liʻiliʻi ma kahi kokoke i ke koʻokoʻo metala e hele ana i loko o ka solenoid valve coil, a laila e electrify ka solenoid valve. Inā manaʻo ka magnetic, a laila maikaʻi ka coil valve solenoid, inā ʻaʻole ia he hewa.
