Liugong excavator solenoid valve coil i loko anawaena 19mm

ʻElua mau ʻāpana o ka solenoid valve: electromagnetic coil a me magnetic core. Ke hoʻopau ʻia ka coil i loko o ka valve solenoid, ʻo ka hana o ka magnetic core e hoʻolilo i ka wai i loko o ke kino valve a ʻoki ʻia, pēlā e hoʻololi ai i ke kuhikuhi o ka wai. Ma muli o ka hele ʻana o ka ʻāwīwī i loko o ka wili, hiki ke hoʻopau ʻia ka coil valve solenoid. ʻOiaʻiʻo, ʻokoʻa paha nā kumu o ka puhi ʻana. E nānā kākou i nā kumu o ka pau ʻana o ka puʻupuʻu solenoid valve. I ka hōʻuluʻulu ʻana, ʻo nā kumu o ke ahi ʻana o ka solenoid valve coil maʻamau:

1 pilikia ka maikaʻi o ka coil, e wela ka hana pinepine.

2. Hoʻopau i ka haki ʻana koke o ka piʻi ʻana o ka overvoltage;

3 kiʻekiʻe loa ka mana lako uila, puhi pololei.

4 Ka hopena hou, on-off pinepine e hana i ka overcurrent a i ʻole overheating;

ʻO ka hiki ʻole o ka hoʻokomo ʻana a me ka haʻalulu mechanical nui e alakaʻi i ka ʻaʻahu coil, haki uea a me ke kaapuni pōkole.

No laila pehea e ʻike ai i ka coil valve solenoid?

ʻO ke ala maʻalahi ka hoʻohana ʻana i ka multimeter e ana i ke kū'ē o ka valve solenoid. ʻO ke kūpaʻa o ka coil ma kahi o 100 ohms! Inā pau ʻole ke kūʻē o ka coil, ʻo ia hoʻi, ua haki ia. Inā he mea maʻamau ke kūpaʻa i ana ʻia, ʻaʻole ia he manaʻo he maikaʻi ka wili. 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 ʻoe i ka magnetism, a laila maikaʻi ka solenoid valve coil, inā ʻaʻole ia he hewa.

ʻO ka mea i luna nei ka hoʻolauna ʻana i nā kumu o ke ahi o ka coil valve solenoid. No nā kumu o waho a i ʻole nā ​​​​kumu o loko, pono ia e huki i ko mākou nānā. I ka hoʻohana maʻamau, pono e pale ʻia ka wai mai ke komo ʻana i ka valve solenoid, a pono e nānā ʻia ka valve solenoid i kēlā me kēia manawa e hōʻoia i ka hiki ke hoʻohana ʻia ka solenoid valve no ka manawa lōʻihi.
