Excavator solenoid valve 457-9878 hydraulic pump proportional solenoid valve

1, hoʻolālā valve proportional.

ʻO ka valve proportional kahi ʻano hou o ka mea hoʻokele hydraulic. Hiki ke hoʻomalu mamao ʻia ke kaomi, kahe, a i ʻole ke kuhikuhi ʻana o ke kahawai ʻaila e like me ka hōʻailona uila hoʻokomo mau a me ka like. Hoʻokumu ʻia ka valve proportional i ʻelua mau ʻāpana: ka mīkini hoʻololi hoʻololi electro-mechanical a me ke kino hoʻokele hydraulic.

Nui nā ʻano o nā electromagnets proportional, akā ʻo ka loina hana ma ke ʻano like, a ua hoʻomohala ʻia lākou a pau e like me nā pono mana o ka valve proportional. ʻO kāna hana ʻo ia ka hoʻololi mau ʻana i ka hōʻailona uila hoʻokomo i loko o ka ikaika mechanical a me ka hoʻoneʻe ʻana, a ʻo ka mea hope e hoʻopuka i ke kaomi a me ke kahe ʻana i ka proportionally a me ka hoʻomau ʻana ma hope o ka ʻae ʻana i ka ikaika mechanical a me ka neʻe ʻana.

2. 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.

Kumu o ka solenoid valve proportional

Hoʻokumu ʻia ia ma ke kumu o ka solenoid switch valve: i ka wā e ʻoki ʻia ai ka mana, kaomi pololei ka pūnāwai i ke kumu hao i ka noho, e pani ana i ka valve. Ke hoʻoikaika ʻia ka coil, ʻo ka hopena electromagnetic ikaika e lanakila ai 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 solenoid on-off valve: ke kaulike ka pūnāwai a me ka ikaika electromagnetic ma lalo o kekahi manawa coil. ʻO ka nui o ka coil i kēia manawa a i ʻole ka nui o ka ikaika electromagnetic e hoʻopilikia i ka hahau o ka plunger a me ka wehe ʻana o ka valve, a ʻo ka wehe ʻana o ka valve (ka kahe kahe) a me ka coil current (control signal) he pilina laina kūpono. . Kahe pololei nā ʻūhā solenoid kūpono ma lalo o ka noho. Ke kahe nei ka waena ma lalo o ka noho valve, a ʻo kona kuhikuhi ʻana o ka ikaika e like me ka ikaika electromagnetic, akā ʻo ke ʻano o ka pūnāwai. No laila, pono e hoʻonohonoho i ka huina o nā waiwai kahe liʻiliʻi e pili ana i ka pae hana (coil current) i ke kūlana hana. Ke pio ka mana, ua pani ʻia ka pahu solenoid proportional Drake (pani mau ʻia).

Hana ʻana o ka valve solenoid

Loaʻa ka mana throttle o ka kahe kahe e ka mana uila (ʻoiaʻiʻo, hiki ke hoʻokō ʻia ka mana kaomi e nā hoʻololi hoʻololi, etc.). No ka mea ʻo ia ka mana throttle, pono e nalowale ka mana.
