Excavator hydraulic pump solenoid valve 174-4913 solenoid valve

Solenoid valve hui hoʻonā hewa:

1, pau ka wili i ke ahi

ʻO ka hana lōʻihi o ka solenoid valve, ʻaʻole e pau ka coil, inā ʻaʻole ʻaila ka solenoid valve ma hope o ka hoʻopili ʻana, ʻano ʻole ka coil. A ʻaʻohe omo i loko o ka mandrel, e hōʻike ana ua puhi ʻia ka coil a pono e hoʻololi ʻia ka coil electromagnetic.

2. Leo ʻano ʻē

I kekahi manawa i ka wā e hoʻohana ʻia ai ka pahu solenoid, e kani ʻia ka AC, no ka mea ua hemo ka coil nut, a laila e hoʻomaʻemaʻe ʻia ka pahu pailaka e wehe i ka mea ʻē i loko, a laila e hoʻopaʻa i ka nut.

3. Paʻa ka solenoid valve

ʻO ka maʻamau, he liʻiliʻi loa ka ʻāpana ma waena o ka lima paheʻe paheʻe a me ka spool o ka valve solenoid, ʻoi aku ka liʻiliʻi ma mua o 0.008 mm, a paʻa maʻalahi ka pahu solenoid i ka wā e komo ai nā haumia a i ʻole ka liʻiliʻi o ka ʻaila lubricating.

Penei paha ke ano o ka hewa ma hope o ka poino ana o ka valve proportional: 1, paa ka spool: he pa'a ole ka puka ana o ka valve proportional, a ua loli nui ke kahe. 2, ʻoi aku ka nui o ka leakage: kahe ka ʻaila proportional valve, e pili ana i ka paʻa a me ka pololei o ka ʻōnaehana hydraulic. 3, puhi ʻia ka coil: ʻaʻole hiki ke hana pono ka valve proportional, ʻaʻole ka mana o ka ʻōnaehana hydraulic. 4, lohi ka pane pane: pane mālie ka valve proportional i ka hōʻailona uila, e pili ana i ka hana ikaika o ka ʻōnaehana. 5, nui ka piʻi ʻana o ke kaomi: ʻaʻole paʻa ka paʻi puka o ka valve proportional, e pili ana i ka hana maʻamau o ka ʻōnaehana hydraulic. Eia hou, ina ua poino ka puuwai proportional, hiki no hoi ke pilikia e like me ka lawa ole o ka wela o ka wai wela, ka wela a me ke anu o ka wai wela o ka hale, ka pulupulu ma'amau aka, aole i lanakila, a me ke ahi fuse i ka hoomaka ana i ka umu e kau ana i ka paia.
