Excavator hydraulic pump proportional solenoid valve 200-6210

Hoʻomalu ʻia ka spool o ka valve solenoid proportional e nā electromagnets proportional, no laila ke kūlike ka pihi puka a i ʻole ke kahe i ka manawa komo. No laila, hiki ke hoʻomau mau ʻia ke kaomi puka ʻana a i ʻole ke kahe ʻana ma o ka hoʻololi ʻana i ka hōʻailona hoʻokomo. Loaʻa i kekahi mau valve ka hana o ka hoʻomalu ʻana i ka nui a me ke kuhikuhi. E like me ka proportional valve hiki ke hoʻokaʻawale ʻia i loko o: puʻuwai proportional valve, kahe proportional valve, reversing valve ʻekolu mau ʻāpana.
Hoʻohana ʻia ka valve proportional e hoʻololi i ka ʻāpana mana kumu me kahi electromagnet proportional ma ka valve kaomi maʻamau, ka valve kahe a me ka valve kuhikuhi, a no ka hoʻokele mamao ʻana i ke kaomi, kahe a kuhikuhi paha o ka kahe aila e like me ka hōʻailona uila hoʻokomo mau a me ka like. . Loaʻa i nā valve proportional ka uku pānaʻi, a ʻaʻole hiki ke hoʻopili ʻia ke kaomi puka a me ke kahe kahe e nā loli ukana.
Hiki i ka valve proportional ke hoʻomalu i ka nui o ka puka me ka nalu PWM, a ke hoʻomau nei ka puka.
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.
