Loader excavator mea lako 278-1799 solenoid valve Hydraulic valve 226-9622

ʻO nā hewa maʻamau ʻaʻole i hana ka solenoid valve, pono e nānā ʻia mai nā ʻano aʻe:

1. Ua hemo ka mea hoʻopili solenoid valve a i ʻole ua pio ka uea, ʻaʻole uila ka solenoid valve, a hiki ke hoʻopaʻa ʻia ka mea hoʻopili uea.
2, ua puhi ʻia ka solenoid coil, hiki iā ʻoe ke wehe i ka solenoid valve wiring, ana me ka multimeter, inā wehe ʻia, pau ka solenoid coil. ʻO ke kumu o ka puʻupuʻu o ka coil, ke kumu o ka insulation maikaʻi ʻole a me ka leakage magnetic, e hoʻonui ai i ke au o ka coil i ka nui a wela, no laila pono e pale i ka ua mai ke komo ʻana i ka solenoid valve. Eia kekahi, ikaika loa ka pūnāwai, nui loa ka hopena o ka hopena, liʻiliʻi loa ka huli ʻana o ka coil, a ʻaʻole lawa ka suction hiki ke hana i ke ahi. Inā pilikia, hiki ke kaomi i ke pihi manual ma ka coil mai ke kūlana "0" i ka hana maʻamau i ke kūlana "1" e wehe i ka valve.
3, paʻa ka solenoid valve: ka solenoid valve lima a me ka spool me kahi liʻiliʻi liʻiliʻi (ma lalo o 0.008mm), maʻamau hoʻokahi.
ʻO ka hui ʻāpana, ke loaʻa nā mea haumia mechanical a i ʻole ka ʻaila lubricating liʻiliʻi, maʻalahi ke paʻa. ʻO ke ʻano lapaʻau e hiki ke hoʻohana i ke kaula kila ma ka puka liʻiliʻi o ke poʻo e hoʻihoʻi ai. ʻO ka hopena koʻikoʻi ʻo ka wehe ʻana i ka pahu solenoid, lawe i ka spool a me ka lima spool, a hoʻomaʻemaʻe me CCI4, i hiki ke maʻalahi ka spool i ka lima valve. I ka wehe ʻana, pono e nānā i ke kaʻina hui a me ke kūlana uwea waho o kēlā me kēia ʻāpana, i mea e hui hou ai a uea pololei, a e nānā inā paʻa ka lua o ka aila a inā lawa ka aila lubricating.
