Loader excavator accessories 375-4414 Hydraulic valve

Zvikanganiso zvakajairika ndezvekuti solenoid valve haishande, iyo inofanirwa kuongororwa kubva pane zvinotevera zvinhu:

1. Iyo solenoid valve connector yakasununguka kana tambo yekubatanidza yakavharwa, solenoid valve haisi yemagetsi, uye tambo yekubatanidza inogona kusimbiswa.
2, iyo solenoid coil inopiswa kunze, unogona kubvisa solenoid valve wiring, kuyerwa ne multimeter, kana yakavhurika, iyo solenoid coil inopiswa kunze. Chikonzero ndechekuti iyo coil inonyorova, inokonzera kuvharika kwakashata uye kudonha kwemagineti, zvichiita kuti ikozvino mucoil ive yakakura uye yakapiswa, saka zvakakosha kudzivirira mvura kuti isapinda muvharuvhu solenoid. Mukuwedzera, chitubu chakanyanya kusimba, simba rekuita rakakurisa, makoiri anotendeuka akawandisa, uye kusveta hakuna kukwana kunogona kuita kuti coil ripise. Muchiitiko chekukurumidzira, bhatani remanyorero pacoil rinogona kudzvanywa kubva panzvimbo ye "0" mune yakajairika kushanda kuenda kune "1" chinzvimbo kuti vharafu rivhure.
3, iyo solenoid vharafu inonamira: iyo solenoid vharafu sleeve uye spool ine diki clearance (isingasviki 0.008mm), kazhinji isina kuroora.
Kuungana kwechikamu, kana paine kusvibiswa kwemichina kana mafuta ekuzora mashoma, zviri nyore kunamira. Nzira yekurapa inogona kunge iri waya yesimbi kuburikidza neburi diki remusoro kuti idzoke. Mhinduro yakakosha ndeyekubvisa solenoid valve, bvisa spool uye spool sleeve, uye kuchenesa neCCI4, kuitira kuti spool ikwanise kuchinjika muvharuru sleeve. Paunenge uchibvisa, kutarisisa kunofanirwa kubhadharwa kune kutevedzana kwegungano uye nzvimbo yekunze wiring yechikamu chimwe nechimwe, kuitira kuti uunganidze zvakare uye waya nemazvo, uye tarisa kana gomba rekupfapfaidza mafuta rakavharwa uye kana mafuta ekuzora akwana.

Kutyaira kwakasiyana. Chishandiso chekutyaira cheiyo proportional valve ndiyo yakaenzana electromagnet, uye mudziyo wekutyaira wevhavhavhavha yeservo ndiyo mota yekumanikidza kana torque mota, uye maparamita ekuita akasiyana. Hysteresis, nzvimbo yepakati yakafa, bandwidth, kukwenenzverwa uye humwe hunhu hwakasiyana, saka nguva dzekushandisa dzakasiyana, mavharuvhu eservo uye servo proportional mavharuvhu anonyanya kushandiswa muakavharika-loop control system, proportional mavharuvhu ezvimwe zvimiro anonyanya kushandiswa mukuvhurika loop. kudzora masisitimu uye yakavharwa-loop kumhanya kudzora masisitimu.
Simba rekupinza reiyo general proportional vharafu rakakura, zvakanyanya mumazana eMa kusvika 1 amp kana kupfuura, uye simba rekupinza revharuvhu rakajairwa rakakura.
Diki, zvakanyanya mumakumi eMA; Kurongeka kwekutonga kwevhavhavha yakaenzana yakaderera zvishoma, iyo hysteresis yakakura kudarika yevhavhavha yevhavhavha, uye kutonga kwakarurama kwevhavha yakazara yakakwirira, asi zvinodiwa nemafuta zvakare zvakakwirira.
Zvinonzwisiswa kubva muchimiro kuti spool yevhavha inoenzanirana yakaenzana nemagetsi emagetsi uye hydraulic pressure uye chitubu simba, nepo yakajairika vharafu inoenzanirana ne hydraulic pressure, saka proportional valve haina pundutso mukudzora kuyerera kukuru uye kukwira kwakanyanya. Kune proportional mavharuvhu zvigadzirwa zvekutanga zvakavhurika, izvo zvinofanirwa kunge zviri chikonzero nei zvichinzi proportional mavharuvhu.
