Excavator solenoid valve set 423-4562 proportional solenoid valve

Electromagnetic proportional valve kushanda musimboti uye kuona:

Valve control yekuyerera inogona kukamurwa kuva marudzi maviri:
Imwe ndeye switch control: ingave yakavhurika zvizere kana kuvharwa zvakazara, mwero wekuyerera ungave wakakura kana diki, hapana nzvimbo yepakati, seyakajairwa magineti emagetsi kuburikidza nemavharuvhu, mavharuvhu ekudzosera emagetsi, electro-hydraulic reversing valves.
Imwe yacho inoramba ichidzora: chiteshi chevhavha chinogona kuvhurwa zvichienderana nekudiwa kwechero dhigirii rekuvhura, nekudaro kudzora saizi yekuyerera kuburikidza, mavharuvhu akadaro ane manyorero ekutonga, senge throttle mavharuvhu, asi zvakare anodzorwa nemagetsi, senge proportional. mavharuvhu, servo mavharuvhu.
Saka chinangwa chekushandisa proportional valve kana servo valve ndeye: kuwana kuyerera kwekutonga nemagetsi kutonga (zvechokwadi, mushure mekuchinja kwemaitiro kunogonawo kuwana kudzvinyirira kutonga, nezvimwewo), sezvo iri throttling control, panofanira kuva nekurasikirwa kwesimba, servo. vharafu nemamwe mavharuvhu akasiyana, kurasikirwa kwayo kwesimba kwakakura, nekuti inoda kumwe kuyerera kuchengetedza basa reiyo pre-stage control oil circuit.

Kushanda nheyo yeproportional solenoid valve

Inobva pamusimboti we solenoid on-off valve: kana simba rapera, chitubu chinotsikirira musimboti wakanangana nechigaro, zvichiita kuti valve ivhare. coil
Kana magetsi akaiswa, simba remagetsi rinogadzirwa rinokunda simba rechirimo uye rinosimudza musimboti, nokudaro richivhura vharuvhu. Iyo proportional solenoid valve inoita shanduko kune chimiro chesolenoid valve: inogadzira chiyero pakati pechitubu simba nemagetsi emagetsi pasi pechero coil ikozvino. Saizi yekoiri yazvino kana saizi yesimba remagetsi inokanganisa plunger sitiroko uye kuvhurika kwevharuvhu, uye kuvhurika kwevharuvhu (kuyerera) uye coil ikozvino (chiratidzo chekudzora) hukama hwakanaka hwemutsara.
Direct acting proportional solenoid valve inoyerera pasi pechigaro. Iyo yepakati inoyerera ichibva pasi pechigaro, uye kwakananga kwesimba kwakafanana neremagetsi emagetsi, uye zvakapesana nechisimba chechirimo. Nokudaro, zvakakosha kuisa huwandu uye hushoma hunoyerera hunoenderana nehuwandu hwekushanda (coil current) mumamiriro ekushanda. Iyo proportional solenoid valve yeDrey fluid yakavharwa (NC, inowanzovharwa rudzi) kana simba radzimwa.
