Inokodzera bulldozer CAT 826G proportional solenoid valve Rotary solenoid valve 147-5399

Proportional solenoid valve is a special control solenoid valve, mutemo wayo wekutonga ndeye kudzora kuvhurwa kwevhavha kuburikidza nekunze kwekuisa chiratidzo chekuraira, kuitira kuti kudzora kuyerera uye kumanikidza nguva dzose kuchengetedza chikamu chakafanana sechiratidzo chekuraira. Inoshandisa teknolojia ye "position feedback", iyo inogona kunyatsogadzirisa nzvimbo yevhavha maererano nechiratidzo chekudzora kuyerera, kuitira kuti iwane zvakakodzera kutonga zvinodiwa, saka inoshandiswa zvakanyanya mukugadzirisa hydraulic system control.
 

Nheyo huru yeiyo proportional solenoid vharafu ndeyekuti iyo inoyerera inodzora chiratidzo uye simba rekudzora rinoshandiswa sesosi yesimba remagetsi coil, kuitira kuti electromagnet idzore kuvhurwa kwevhavha, saka kuvhurwa kwevhavha kunenge kuenzana ne saizi yechiratidzo chekudzora kuyerera. Maererano nekuyerera kwakasiyana-siyana, nzvimbo imwe neimwe yekutonga ine chiyero chakasiyana chekuyerera, iyo inodyiswa zvakare kune inoyerera inoyerera, iyo inoyerera inogona kugadzirisa nzvimbo yevhavha maererano nechiratidzo chekubuda kwehukuru hwakafanana nekuyerera pano, kuitira kuti uwane kunyatso kudzora zvinodiwa.

Kushandiswa kwekuchera solenoid valve

Iyo electromagnetic vharafu yekuchera ndeye otomatiki yakakosha chikamu chinoshandiswa kudzora iyo yekuchera fluid, iyo ndeye actuator, uye haina kugumira kune hydraulic uye pneumatic. Inoshandiswa mumaindasitiri ekudzora masisitimu kugadzirisa mafambiro enhau, kuyerera, kumhanya uye mamwe ma paramita. 2, iyo solenoid valve inogona kusanganiswa nematunhu akasiyana-siyana kuti iwane kutonga kunoda, uye kururamisa uye kushanduka kwekutonga kunogona kuvimbiswa. Kune mhando dzakawanda dzemavharuvhu e-solenoid, mavharuvhu akasiyana-siyana anoita basa munzvimbo dzakasiyana dzehurongwa hwekutonga, anonyanya kushandiswa mavharuvhu echeki, mavharuvhu ekuchengetedza, mavharuvhu ekudzora nzira, mavharuvhu ekudzora kumhanya uye zvichingodaro.

DC electromagnet voltage inowanzoita 24 volts. Mabhenefiti ayo ibasa rakavimbika, kwete nekuti spore yakanamatira uye yakatsva, hupenyu hurefu, hukuru hudiki, asi simba rekutanga idiki pane iyo AC electromagnet, uye kana pasina DC magetsi emagetsi, kudiwa kwemidziyo yekugadzirisa. Kuti uvandudze kuvimbika kwekushanda uye hupenyu hweiyo electromagnetic reversing valve, mumakore achangopfuura, wet electromagnet iri kuramba ichishandiswa zvakanyanya kumba nekune dzimwe nyika, iyi electromagnet uye slide valve push rod haidi kuiswa chisimbiso, ichibvisa kukwesha pamhepo. Mhete yeO-yakaita sealing, coil yayo yemagetsi kunze yakavharwa zvakananga neinjiniya epurasitiki, kwete imwe simbi goko, iyo inovimbisa kuvharwa, asi zvakare inobatsira pakupisa kupisa, basa rakavimbika, Kuderera kwesimba, hupenyu hurefu.
Parizvino, iyo solenoid vharafu kumba nekune dzimwe nyika yakakamurwa kuita zvikamu zvitatu mumusimboti (kureva: yakananga kuita mhando, nhanho mwana mutyairi rudzi), uye kubva pamusiyano wevharuvhu dhisiki chimiro uye zvinhu uye musiyano wemusimboti wakakamurwa kuita zvidimbu zvitanhatu. (yakananga acting diaphragm chimiro, nhanho mbiri ndiro chimiro, mutyairi firimu chimiro, yakananga acting piston chimiro, nhanho yakananga acting piston chimiro, mutyairi piston chimiro).
Direct acting solenoid valve:
Nheyo: Kana yasimbiswa, simba remagetsi rinogadzirwa nemagetsi emagetsi coil rinosimudza chikamu chekuvhara kubva pachigaro, uye valve inovhura; Kana simba rapera, simba remagetsi rinonyangarika, chitubu chinotsikirira chikamu chekuvhara pachigaro, uye valve yakavharwa.
Zvimiro: Inogona kushanda zvakajairwa pasi pevacuum, kudzvanywa kwakashata uye zero kudzvanywa, asi dhayamita kazhinji haisi kupfuura 25mm.
