Pane musiyano uripo pakati pepfungwa yemagetsi actuator nepneumatic actuator here?

Chishandiso chemagetsi, sechishandiso chepneumatic, chikamu chakakosha chesystem yekudzora. Chinogamuchira chiratidzo chemagetsi che4-20mA kana 0-10mA DC kubva kumutongi uye chinochishandura kuita chinofamba chinoenderana neangular kana linear stroke kuenda kumavharuvhu ekudzora, maflaps nedzimwe nzira dzekudzora dzinoita kuti chidzore otomatiki.

Ma actuator emagetsi anowanikwa mumhando dze straight stroke, angular stroke uye multi-turn. Ma actuator emagetsi eAngular stroke anoshandisa mota yemagetsi sechikamu chesimba kushandura chiratidzo cheDC current chinopinzwa kuita angular displacement inoenderana (0 kusvika 90 degrees). Ma actuator akakodzera kushandisa ma rotary control valves akadai se butterfly valves uye baffles. Ma actuator eStraight stroke anogamuchira chiratidzo cheDC current chinopinzwa uye anotenderera mota, iyo inozoderedzwa ne reduction gear uye inoshandurwa kuita linear displacement output kuti ishandise ma control valves akasiyana-siyana akadai se single, double and three way, uye mamwe ma linear control mechanisms. Ma multi-turn electric actuators anonyanya kushandiswa kuvhura nekuvhara ma multi-turn valves, akadai se gate ne globe valves. Nekuda kwesimba rawo guru remota, makumi e kilowatts, anowanzo shandiswa pa local operation uye remote control. Aya marudzi matatu e actuator masisitimu e position servo anotungamirirwa ne two-phase AC motors. Nheyo nhatu dzemagetsi dzakafanana kunze kwema gearbox akasiyana.

Zviratidzo zvikuru zvekushanda kwe actuator yemagetsi ye angular stroke: nzira yekupinda ine materminal matatu, chiratidzo chekupinda 4-20mA (DC), kuramba kwekupinda 250 Ohm; torque yekubuda: 40,100,250,600,1000N-m; chikanganiso chekutanga uye musiyano uri pasi pe ±1.5%; kunzwa 240μA.

Chishandiso chemagetsi chinosanganisira servo amplifier ne actuator. Servo inogona kubatanidzwa muzvikamu zvakatevedzana. Servo amplifier inogamuchira chiratidzo chekudzora kubva kucontroller uye inochienzanisa nechiratidzo chekupindura kubva ku output actuator ye electric actuator. Kana paine kutsauka, musiyano unowedzerwa simba uye two-phase servo motor inofambiswa kuti itenderere. Output shaft inochinja rotation angle mushure mekunge reducer yadzikira. Kana musiyano uri positive, servomotor inotenderera mberi uye output shaft angle inowedzera. Kana musiyano uri negative, servo motor inodzokera shure uye output axis angle inoderera. Kana musiyano uri zero, servo amplifier inoburitsa contact signal kuti imire mota uye output axis inogadzikana panzvimbo yekona inoenderana ne input signal. Iyi position feedback structure inopa hukama hwakanaka pakati pe input current uye output displacement.

Chishandiso chemagetsi chinogona kushandiswa kwete chete necontroller yekudzora otomatiki, asiwo neoperator yekuchinja otomatiki pakati pekudzora otomatiki uye nemaoko kwesystem yekudzora. Kana switch yemushandisi yakaiswa panzvimbo yekushanda nemaoko, simba remota rinodzorwa zvakananga nemabhatani ekufambisa mberi nekudzoka ekutenderera mberi kana kumashure kweshaft yekuburitsa actuator uye kushanda nemaoko kure kweactuator.
