Inokodzera CAT Carter 2522237 excavator accessories solenoid valve 252-2237 24V

Proportional solenoid valve

Mashandiro azvinoita:

Yese solenoid valve zvikamu ndeye electromagnetic coil maererano nechikamu chemagetsi, kureva, inductor. Kana iyo inductor yapihwa chiratidzo chemagetsi, iyo electromagnetic munda inogadzirwa neazvino ichaita kuti vheji yepakati ifambe uye kuona shanduko yemaparamita anodzorwa.
Kuzivikanwa kwemhando
Imwe neimwe electromagnetic coil ine yakamira yekupikisa kukosha R, asi iyi R haigone kuve "0" kana "∞", kana R= "0" inoratidza mukati mapfupi dunhu: kana R= "∞" inoratidza yemukati yakavhurika dunhu; pamwe
Kupokana kwekoiri kune imba hakugone kuve "0". Kana mamiriro ari pamusoro apa achigona kusangana uye solenoid valve isingashande, zvingave kuti chiratidzo chekuisa chinenge chisina kunaka kana kuti nheyo yevhavha yakanamatira.

Pressure sensor

Mashandiro azvinoita:

Kune matatu-waya pressure sensor sensor, inogona kunzwisiswa seye-tatu-waya potentiometer kana variable resistor, kazhinji ichiwedzera 5V voltage kune maviri emitsara (1 mutsara uye 3 mitsara), uye kana kuyerwa kukosha kwachinja, voltage mutsetse wepakati (mitsetse miviri) inoshanduka pakati pe0 ne5V.

Kuzivikanwa kwemhando
1. Tungamira kunze mutsara wepakati, shandura chiratidzo chakayerwa, shandisa multimeter kuyera kana voltage yepakati mutsara (2 mitsetse) inoshanduka neyakayerwa chiratidzo.
2. Yambuka sensor pasina kukanganisa

Iyo misimboti yekushanda yeproportional electromagnetic control valve inounzwa

Inobva pamusimboti we solenoid on-off valve: kana simba rapera, chitubu chinotsikirira musimboti wakanangana nechigaro, zvichiita kuti valve ivhare. Kana iyo coil yasimbiswa, 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 maitiro makuru uye maduku ekuyerera anoenderana nehuwandu hwekushanda (coil current) mumamiriro ekushanda. Iyo proportional solenoid valve yeDrey fluid yakavharwa (NC, inowanzovharwa rudzi) kana simba radzimwa.
