Nā ʻāpana mīkini hana SV98-T3003 24V no John Deere solenoid valve

ʻO ka nānā ʻana a me ka hoʻopau ʻana i ka hāʻule ʻana o ka valve puʻe

No ka mea, aia wale nō ka valve kaomi proportional ma ke kumu o ka valve kaomi maʻamau, ua hoʻololi ʻia ka mea hoʻoponopono e kahi electromagnet proportional. No laila, ʻo nā hewa like ʻole i hana ʻia e ka valve kaomi maʻamau, ka mea e hoʻopuka ai i nā kumu hewa a me nā ʻano hoʻopau ʻana o ka valve kaomi maʻamau e pili pono ana i ka valve kaomi proportional like (e like me ka valve relief proportional). lawelawe ʻia e ka kuhikuhi. Kahi mea hou aʻe:

① ʻAʻole i loaʻa i kēia manawa ka electromagnet proportional, i hiki ke nānā ʻia ka hemahema o ka hoʻoponopono ʻana i kēia manawa e like me ka ʻike "(1) proportional electromagnet fault" ma luna. Ke hiki ʻole ka hoʻoponopono ʻana i ka volta, hiki iā ʻoe ke nānā mua i ke kumukūʻai o kēia manawa me kahi mika uila e hoʻoholo ai inā he pilikia me ke kaapuni mana o ka electromagnet, a i ʻole ka pilikia me ka electromagnet proportional, a i ʻole ka pilikia me ka ʻāpana valve. hiki ke hōʻailona.

② ʻOiai ua helu ʻia ke kahe o kēia manawa ma ka electromagnet proportional, akā ʻaʻole i piʻi iki ke kaomi, a ʻaʻole i loaʻa ke kaomi i koi ʻia, ma waena o ka mea hoʻoponopono paʻi pilot proportional (relief valve) a me ka pahu hoʻomaha nui, ka mea hoʻoponopono manual pilot. ʻO ka pahu hoʻomaha hoʻokele maʻamau e paʻa mau ana, e pāʻani ana i ke kuleana o ka valve palekana ma ʻaneʻi. Ke haʻahaʻa loa ke kaomi hoʻoponopono valve, ʻoiai ua helu ʻia ka electromagnet proportional ma o kēia manawa, akā ʻaʻole e piʻi ka piʻi, inā haʻahaʻa loa ke kaomi ʻana o ka valve, e kahe ka pailaka mai ka valve i ka pahu, no laila. ʻaʻole hiki mai ke kaomi. I kēia hihia, pono e hoʻonui ʻia ke kaomi hoʻonohonoho valve ma kahi o 1MPa ma mua o ke kaomi hana kiʻekiʻe o ka valve.

(3) He nui loa ke kahe e kahe ana ma ka electromagnet proportional, akā ʻaʻole i piʻi ka piʻi, a i ʻole hiki ke nānā ʻia ke kaomi i koi ʻia i kēia manawa i ke kūpaʻa coil o ka electromagnet proportional, inā ʻoi aku ka liʻiliʻi ma mua o ka waiwai i kuhikuhi ʻia, a laila ua haki ke kaapuni o loko o ka coil electromagnet; Inā maʻamau ka pale ʻana o ka coil electromagnet, a laila pōkole ka pili ʻana i ka amplifier proportional. I kēia manawa, pono e hoʻololi i ka electromagnet proportional, a pono e hoʻopili ʻia ka pilina, a i ʻole e hoʻokomo ʻia ka coil rewound.
