I-excavator hydraulic pump solenoid valve proportional solenoid valve TM68401

Iimpawu ze-proportional solenoid valves

I-1) Iyakwazi ukuqonda ukulungelelaniswa okungapheliyo koxinzelelo kunye nesantya, kwaye ugweme into echaphazelayo xa i-valve yokutshintsha evulekileyo iguqulwa.

2) Ulawulo olukude kunye nolawulo lweprogram lunokuphunyezwa.

3) Xa kuthelekiswa nolawulo oluphakathi, inkqubo yenziwe lula kwaye amacandelo ayancipha kakhulu.

I-4) Xa kuthelekiswa ne-valve ye-hydraulic proportional valve, incinci ngobukhulu, ilula ngesisindo, ilula kwisakhiwo kunye nexabiso eliphantsi, kodwa isantya sokuphendula sihamba kancinci kunenkqubo ye-hydraulic, kwaye iphinda ivelele ekulayisheni utshintsho.

5) Amandla aphantsi, ukushisa okuphantsi, ingxolo ephantsi.

6) Akuyi kubakho mlilo kwaye akukho ngcoliseko lokusingqongileyo. Ayichatshazelwa kangako lutshintsho lobushushu.

Umgaqo-siseko we-proportional solenoid valve

Isekelwe kumgaqo we-valve yokutshintsha kwe-solenoid: xa amandla enqunyulwa, intwasahlobo icinezela intsimbi yentsimbi ngokuthe ngqo kwisihlalo, ukuvala i-valve. Xa ikhoyili inikwe amandla, amandla avela kwi-electromagnetic ayoyisa amandla asentwasahlobo kwaye aphakamise undoqo, ngaloo ndlela avule ivalve. Ivalve ye-solenoid elinganayo yenza utshintsho oluthile kwisakhiwo se-solenoid on-off valve: amandla entwasahlobo kunye ne-electromagnetic force zilungelelaniswa phantsi kwayo nayiphi na i-coil current. Ubungakanani bekhoyili yangoku okanye ubungakanani bamandla e-electromagnetic buya kuchaphazela ukubetha kwe-plunger kunye nokuvulwa kwevalve, kunye nokuvulwa kwevalve (inqanaba lokuhamba) kunye nekhoyili yangoku (uphawu lolawulo) banobudlelwane obufanelekileyo bomgca. . Iivalvu ze-solenoid ezisebenza ngokuthe ngqo zihamba phantsi kwesitulo. Isiphakathi sihamba phantsi kwesihlalo sevalve, kwaye isalathiso saso samandla siyafana namandla ombane we-electromagnetic, kodwa ngokuchaseneyo namandla entwasahlobo. Ngoko ke, kuyimfuneko ukuseta isamba samanani amancinci amancinci ahambelana noluhlu lokusebenza (coil current) kwimeko yokusebenza. Xa umbane ucinyiwe, ivalve ye-Drake liquid proportional solenoid ivaliwe (ngokuqhelekileyo ivaliwe).
