He kūpono no CAT Carter 2522237 excavator mea komo solenoid valve 252-2237 24V

Kiwikā solenoid proportional

Pehea e hana ai:

ʻO nā ʻāpana valve solenoid āpau he coil electromagnetic e pili ana i ka ʻāpana uila, ʻo ia hoʻi, kahi inductor. Ke hāʻawi ʻia ka inductor i kahi hōʻailona uila, ʻo ke kahua electromagnetic i hana ʻia e ka manawa e hoʻoneʻe i ke kumu valve a ʻike i ka hoʻololi ʻana o nā ʻāpana hoʻomalu.
ʻIke maikaʻi:
Loaʻa i kēlā me kēia huila electromagnetic kahi waiwai kūʻokoʻa R, akā ʻaʻole hiki ke "0" a i ʻole "∞" kēia R, ke hōʻike ʻo R = "0" i ke kaapuni pōkole i loko: ke hōʻike ʻo R = "∞" i ke kaapuni hāmama i loko; me
ʻAʻole hiki ke "0" ke kū'ē o ka coil i ka hale. Inā hiki ke hoʻokō ʻia nā kūlana ma luna aʻe a ʻaʻole hana ka solenoid valve, hewa paha ka hoʻokomo ʻana i ka hōʻailona a paʻa paha ke kumu valve.

ʻIke paʻi

Pehea e hana ai:

No ka mea ʻike puʻe ʻekolu uea, hiki ke hoʻomaopopo ʻia he potentiometer 3-wire a i ʻole resistor variable, e hoʻohui pinepine i ka volta 5V i ʻelua laina (laina 1 a me 3 laina), a i ka wā e loli ai ka waiwai i ana ʻia, e hoʻohui ʻia ka voltage o hoʻololi ka laina waena (2 laina) ma waena o 0 a me 5V.

ʻIke maikaʻi:
1. E alakaʻi i waho o ka laina waena, e hoʻololi i ka hōʻailona ana, e hoʻohana i ka multimeter e ana inā paha e hoʻololi ka volta o ka laina waena (2 laina) me ka hōʻailona ana.
2. Keʻa i ka ʻike me ka hewa ʻole

Hoʻokomo ʻia ka loina hana o ka valve control electromagnetic proportional

Hoʻokumu ʻia ia ma ke kumu o ka solenoid on-off valve: i ka pau ʻana o ka mana, kaomi pololei ka pūnāwai i ke kumu i ka noho, e pani ai ka valve. Ke hoʻoikaika ʻia ka coil, ʻo ka ikaika electromagnetic i hana ʻia e lanakila i ka ikaika o ka puna a hoʻokiʻekiʻe i ke kumu, pēlā e wehe ai i ka valve. Hoʻololi ka valve solenoid proportional i ke ʻano o ka valve solenoid: hana ia i ke kaulike ma waena o ka ikaika o ka puna a me ka ikaika electromagnetic ma lalo o kekahi manawa coil. ʻO ka nui o ka coil current a i ʻole ka nui o ka ikaika electromagnetic e pili ana i ka plunger stroke a me ka wehe ʻana o ka valve, a ʻo ka wehe ʻana o ka valve (kahe) a me ke ʻano o ka coil (hōʻailona mana) he pilina laina kūpono. E kahe ana ka valve solenoid proportional pololei ma lalo o ka noho. Kahe ka waena mai lalo mai o ka noho, a ua like ke kuhikuhi o ka ikaika me ka ikaika electromagnetic, a me ke ku e o ka ikaika puna. No laila, pono e hoʻonohonoho i nā waiwai kahe nui a me ka liʻiliʻi e pili ana i ka pae hana (coil current) i ke kūlana hana. Ua pani ʻia ka valve solenoid proportional o ka wai Drey (NC, ʻano paʻa maʻamau) ke pio ka mana.
