Relief vharuvhu PC220-6 Excavator kuchengetedza vharafu 708-2L-04740

Kune marudzi akawanda emavharuvhu e solenoid pane zvidiki zvekuchera. Chokutanga pane zvose, tinofanira kuziva nheyo yekushanda yevhavha ye solenoid. Iyo solenoid vharafu yemuchina wekuchera inoshandisa electromagnet kusundira vheji yepakati kudzora kwainoenda kumhepo yakamanikidzwa, kudzora kwainoenda kwepneumatic actuator switch. Electromagnetic directional valve zvinoenderana nezvinodiwa zvakasiyana inogona kuwana mbiri-nzira, mbiri-nzira shanu uye zvichingodaro
Kutanga, chimiro chevharuvhu ye solenoid: coil, magineti, ejector tsvimbo.

Nheyo yekushanda ye solenoid vharafu yemucheki mudiki ndeyekuti kana coil yakabatana neyazvino, inogadzira magineti, inokwezva mumwe nemumwe nemagineti, iyo magineti inodhonza ejector tsvimbo, inodzima simba, iyo magineti uye ejector tsvimbo. vanoiswa patsva, uye maitiro ekushanda anopedzwa.

Chechipiri, iyo electromagnet inoshandiswa kushandisa solenoid valve pane diki yekuchera yakakamurwa kuita AC uye DC.

Iyo voltage ye AC electromagnet inowanzoita 220V, iyo inoratidzwa nemasimba makuru ekutanga, nguva pfupi yekudzosera uye mutengo wakaderera. Nekudaro, kana iyo yepakati yevharuvhu isina kunamira zvakakwana uye musimboti wesimbi usina kuyamwa, iyo electromagnet iri nyore kupisa nekuda kwekunyanyisa ikozvino, saka mukana wekushanda hauna kunaka, chiitiko chine simba, uye hupenyu hupfupi. Iyo voltage yeDC electromagnet inowanzoita 24V, uye chakanakira ndechekuti inoshanda nekuvimbika, haizotsva nekuda kwekunamatira spore, uye ine hupenyu hwakareba.

Chechitatu, kupatsanurwa kwe solenoid valves

1, yakananga inoshanda solenoid vharafu
Kana simba racho riri, simba remagetsi rinogadzirwa nemagetsi emagetsi coil rinosimudza chidimbu chekuvhara kubva pachigaro, uye valve inodanwa. Kana simba rapera, solenoid valve inonyangarika, chitubu chinotsikirira chikamu chekuvhara pachigaro, uye valve yakavharwa. Iyo inoratidzirwa neyakajairwa kushanda muvacuum, kudzvanywa kwakashata uye zero kudzvanywa, asi dhayamita kazhinji haisi kupfuura 25mm.

2, mutyairi solenoid vharafu
(Pilot solenoid valve kushanda musimboti)

Kana yakabatidzwa, simba remagetsi remagetsi rinovhura gomba rekutyaira, kudzvanywa kwekamuri yekumusoro kunodonha nekukurumidza, kuchiita mutsauko wakaderera uye wepamusoro wakatenderedza chikamu chekuvhara, iyo inovhara mvura inosunda chikamu chinovhara kuti chiende kumusoro, uye vharafu inovhura. Kana simba radzimwa, simba remuchirimo rinovhara gomba rekutyaira, uye mhepo inopinza inoumba musiyano wakaderera uye wepamusoro wakatenderedza vharafu inovhara chikamu kuburikidza neburi rekubypass nekukurumidza, uye kumanikidza kwemvura kunosundira chikamu chinovhara kuti chiende pasi nekuvhara. vharafu. Iyo inoratidzirwa nepamusoro wepamusoro muganho weiyo fluid pressure range uye inogona kuiswa zvisina tsarukano (kuti igadziriswe) asi inofanirwa kusangana neiyo fluid pressure pressure musiyano mamiriro.
