Loader excavator lako XKCH-00022 solenoid valve Hydraulic valve

He aha ka ʻokoʻa ma waena o ka valve proportional a me ka valve solenoid maʻamau?

ʻO ka valve proportional kahi ʻano hou o ka mea hoʻokele hydraulic. I loko o ka valve kaomi maʻamau, ka valve kahe a me ka valve kuhikuhi, hoʻohana ʻia ka electromagnet proportional e hoʻololi i ka ʻāpana mana kumu, e like me ka uila komo.
ʻO ka hōʻailona kinoea e hoʻomau mau a me ka proportionally kaohi i ke kaomi, kahe, a i ʻole ke kuhikuhi o ke kahawai ʻaila ma kahi mamao. Loaʻa i nā valve proportional ka uku pānaʻi hana, a ʻaʻole hiki ke hoʻopili ʻia ke kaomi hoʻopuka a me ke kahe kahe e nā loli ukana.

1, ʻaʻole kūlike ka valve maʻamau i ka mana hoʻomau mau, he ʻano hoʻololi ʻano hana maʻemaʻe hoʻokahi, ʻo ke kuhikuhi ʻana o ka valve, ka nui o ka wehe ʻana a i ʻole ka ikaika hoʻonohonoho puna.
ʻAʻole hiki ke hoʻololi e like me nā kūlana maoli.

2, kūlike ka valve proportional i ka mana hoʻomau mau, e like me ke kūlana maoli e hoʻololi i ka ʻike i hōʻiliʻili ʻia i ka mana o ka uku hoʻopaʻi ʻana, ke kuhikuhi wehe ʻana o ka valve, ka nui o ka wehe a i ʻole.hahai ʻia ka pūnāwai hoʻonohonoho ikaika, e hoʻokō i ke ʻano o nā hoʻololi hoʻomalu mau i ka neʻe. Hiki ke hoʻokaʻawale ʻia ka mana o ka valve i ʻelua ʻano: ʻo ka mana hoʻololi: ʻo ka wehe piha ʻana, a i ʻole ka paʻa paʻa ʻana, ʻo ka kahe, a i ʻole ka liʻiliʻi, ʻaʻohe kūlana waena, e like me ka electromagnetic maʻamau ma o ka valve, electromagnetic reversing valve, electro-hydraulic reversing kiwikā. ʻO ka mea ʻē aʻe ka hoʻomau mau ʻana: hiki ke wehe ʻia ke awa valve e like me ka pono o kēlā me kēia degere o ka wehe ʻana, a laila e kāohi ana i ka nui o ke kahe ʻana, ʻo ia mau valve ka mana lima, e like me nā throttle valves, akā hoʻokele uila ʻia, e like me ka proportional. kiwikā, servo valves.

ʻO ke kumu hana o ka valve proportional:

Hoʻonui ʻia ka hōʻailona kauoha e ka proportional amplifier, a me ka proportional output current to the proportional solenoid of the proportional valve, the proportional solenoid output force and the proportional movement of the valve core position, you can proportional control the flow of the liquid flow and e hoʻololi i ke kuhikuhi o ke kahe wai, i mea e hoʻokō ai i ke kūlana a i ʻole ka mana wikiwiki o ka mea hana. I kekahi mau noi e koi ana i ke kūlana kiʻekiʻe a i ʻole ka pololei o ka wikiwiki, hiki ke hoʻokumu ʻia ka ʻōnaehana hoʻomalu pani pani ʻia ma ka ʻike ʻana i ka neʻe ʻana a i ʻole ka wikiwiki o ka mea hana.
Hoʻokumu ʻia ka valve proportional me DC proportional electromagnet a me hydraulic valve. ʻO ke kumu o ka valve proportional e ʻike i ka mana mau ʻo ia ka ratio
Nui nā ʻano o nā electromagnets proportional, akā ʻo ke ʻano hana like ʻole, ua hoʻomohala ʻia lākou a pau e like me nā pono mana o ka valve proportional.
