Excavator solenoid valve TM90501 hydraulic pump proportional solenoid valve TM1022381

Nā wahi hewa maʻamau o ka valve solenoid

1. Ke komo i loko o ka valve solenoid: Ma hope o ka hoʻohana lōʻihi ʻana, ʻo ka ʻaʻahu ʻana o nā ʻāpana o ka valve solenoid e alakaʻi i ka hoʻopaʻa ʻana i loko, e hopena i ka leakage ea a me nā pilikia ʻē aʻe.

2. Poino Coil: Hoʻopili ʻia ka coil valve solenoid e ka haʻalulu o kēia manawa a me ka wela kiʻekiʻe i ka wā lōʻihi o ka hoʻohana ʻana, hiki ke alakaʻi i ka pōʻino coil.

3. ʻAʻole i hoʻohana ʻia ka punawai: Hiki ke hoʻololi ʻia ka punawai i loko o ka valve solenoid, nāwaliwali elastic a i ʻole ka hana ʻole i ka wā o ka hoʻohana maʻamau, e hopena i ka hana ʻole o ka solenoid valve a ʻaʻole hana ma kahi.

4. Leakage: hiki i ka solenoid valve ke sila i loko a i ʻole ka pōʻino coil a me nā kumu ʻē aʻe ke alakaʻi i ka leakage phenomenon, i hiki ʻole i ka solenoid valve ke hana maʻamau.

5. Hoʻopaʻa ʻia ke ala kinoea: ʻO ka hōʻiliʻili ʻana o ka lepo a me nā ʻōpala a puni ka solenoid valve hiki ke alakaʻi i ka hoʻopaʻa ʻana i ke ala kinoea, ʻaʻole hana maʻamau ka solenoid valve.

6. ʻAʻole hiki i ka mīkini: ʻino nā ʻāpana mechanical, hoʻoponopono hewa a me nā mea ʻē aʻe e hiki ke alakaʻi i ka valve solenoid i paʻa, neʻe ʻole a me nā hemahema ʻē aʻe.

7. Coil kaapuni pōkole a haki paha:

Ke ala ʻike: E hoʻohana mua i ka multimeter e ana i kona on-off, ʻoi aku ka nui o ke kūpaʻa i ka zero a i ʻole ka palena ʻole,
ʻO ia hoʻi, pōkole a haki paha ka wili. Inā he mea maʻamau ke kūpaʻa i ana ʻia (e pili ana i ʻumi o ohm), ʻaʻole ia he manaʻo e pono ka coil (ua ana wau i kahi solenoid coil resistance ma kahi o 50 ohms, akā ʻaʻole hiki ke hana ka solenoid valve, ma hope o ka hoʻololi ʻana i ka coil nā mea āpau. maʻamau), e ʻoluʻolu e hana i kēia hoʻāʻo hope loa: e ʻimi i kahi screwdriver liʻiliʻi, e hoʻokomo iā ia ma kahi kokoke i ke koʻokoʻo metala ma o ka solenoid coil, a laila e hoʻoikaika i ka solenoid valve. Inā manaʻo ka magnetic, a laila maikaʻi ka coil valve solenoid, inā ʻaʻole ia he hewa.

8.Plug/socket pilikia:

Nā hōʻailona hewa:
Inā ʻo ka valve solenoid ke ʻano me kahi plug/socket, aia paha kahi pilikia punawai metala o ke kumu (ua loaʻa i ka mea kākau), pilikia uea ma ka plug (e like me ka hoʻopili ʻana i ke kaula mana i ka uea honua) a me nā mea ʻē aʻe. nā kumu i hiki ʻole ke hoʻouna ʻia ka mana i ka coil. ʻOi aku ka maikaʻi o ka hoʻomaʻamaʻa ʻana i ka wili paʻa ma hope o ka hoʻopaʻa ʻana o ka plug i loko o ke kumu a me ka wili ʻana i ka nati paʻa ma hope o ke koʻokoʻo spool ma ka wili.
