I-Rack ne-pinion actuator
Iyini i-Rack and Pinion actuator?
I-Rack-and-pinion actuators ye-pneumatic, okubuye kubizwe ngokuthi amasilinda ajikelezayo alinganiselwe, ama-activator ajikelezayo asetshenziselwa ukujika, ukuvula, ukuvala, ukuxuba, ukuhlehlisa, ukubeka indawo, ukuqondisa kanye neminye imisebenzi eminingi yemishini ehlanganisa ukuzungezisa okunomkhawulo.Lawa ma-actuator nawo avame ukusetshenziselwa ukwenza ama-automation ama-quarter-turn valves, njengebhola noma ama-butterfly valves.
Ama-actuator e-pneumatic rack-and-pinionguqula amandla omoya ocindezelwe ngesilinda somoya abe ukunyakaza okuzungezayo okuzungezayo.Igesi ehlanzekile, eyomile, necutshunguliwe edingwa yile actuator inikezwa ngesiteshi somoya esicindezelwe esimaphakathi, esivame ukusekela uhla lwamadivayisi womoya ohlelweni lwenqubo.
Izici eziyinhloko ze-Rack kanye ne-Pinion actuator
Uma kuqhathaniswa nezingxenye zabo zokubala zikagesi,Ama-Rack nama-pinion actuators ngokuvamile zihlala isikhathi eside, zilungele kangcono izindawo eziyingozi futhi zibiza kancane.Ngaphezu kwalokho, bavame ukudinga ukulungiswa okuncane futhi banikeze i-torque ephakeme uma kuqhathaniswa nosayizi wabo.
Ukucaciswa kobuchwepheshe kwe-Rack kanye ne-Pinion actuator
Irack eyodwa vs. idizayini yokubeka ekabili
Ama-actuator e-Rack-and-pinion anikezela ngebanga elibanzi kakhulu letorque nokuzungezisa uma kuqhathaniswa nezinye izindlela zokuguqula zokuguqula amandla emigqa abe yitorque ejikelezayo.Isebenza kahle kakhulu futhi ama-torque akwazi ukukhiqiza ukusuka ku-Nm embalwa kuya ezinkulungwaneni eziningi ze-Nm.
Kodwa-ke, enye into engahle ibe khona yokwakheka kwe-rack-and-pinion ukuhlehla.Ukuhlehla kwenzeka lapho amagiya e-rack nama-pinion engaqondani ngokuphelele futhi kukhona igebe elincane phakathi kokuxhumana okuhloselwe ngakunye.Lokhu kungaboni ngaso linye kungabangela ukuguga kwamagiya ngesikhathi somjikelezo wempilo ye-actuator, okubuye kwenyuse ukuhlehla.
Iyunithi yokubeka ephindwe kabili isebenzisa ipheya lamarack ezinhlangothini eziphambene zephinikhodi.Lokhu kusiza ukuqeda ukuhlehla ngenxa yamandla aphikisayo futhi kuphinda kabili itorque ephumayo yeyunithi futhi kukhuphule ukusebenza kahle komshini kwesistimu.Ku-activator ephindwe kabili ekhonjiswe kuMfanekiso 3, amagumbi amabili ezinhlangothini agcwaliswa umoya onomfutho, ophusha ama-pistons phakathi nendawo futhi ubuyisele ama-piston endaweni yokuqala, igumbi eliphakathi nendawo nalo licindezelekile.
Umsebenzi
Ama-actuator e-Rack-and-pinion pneumatic angaba isenzo esisodwa noma esikabili.Kuyenzeka futhi ngalawa ma-actuator ukuthi ahlinzeke ngezitobhi eziningi.
Ukulingisa okukodwa uma kuqhathaniswa nokulingisa kabili
Ku-actuator ebambe iqhaza elilodwa, umoya unikezwa kuphela ohlangothini olulodwa lwepiston futhi unesibopho sokuhamba kwepiston ohlangothini olulodwa kuphela.Ukunyakaza kwe-piston ngakolunye uhlangothi kwenziwa yi-spring mechanical.Ama-actuator asebenza kanyekanye alondoloza umoya ocindezelwe, kodwa enza umsebenzi ohlangothini olulodwa kuphela.Uhlangothi olubi lwamasilinda abamba olulodwa amandla okukhiphayo angahambisani ngokushaya okugcwele ngenxa yamandla entwasahlobo aphikisayo.Umfanekiso wesi-4 ubonisa i-actuator ejikelezayo enendawo eyodwa ebamba kabili.
Ku-actuator ebamba kabili, umoya unikezwa amakamelo ezinhlangothini zombili ze-piston.Umfutho womoya ophezulu ohlangothini olulodwa ungashayela ama-piston kolunye uhlangothi.Ama-actuator asebenza kabili asetshenziswa uma umsebenzi udinga ukwenziwa kuzo zombili izinkomba.Umfanekiso 5 ubonisa i-double-rack pneumatic rotary actuator esebenza kabili.
Enye yezinzuzo zamasilinda abamba kabili amandla okukhiphayo angaguquki ngobubanzi obugcwele bokuzungezisa.Izithiyo zamasilinda asebenza kabili ziyisidingo sazo somoya ocindezelwe ukuze zinyakaze kuzo zombili izinkomba kanye nokuntuleka kwendawo echaziwe uma kwenzeka kuba namandla noma ukwehluleka kwengcindezi.
Ukuma okuningi
Amanye ama-actuator e-rack-and-pinion ayakwazi ukuma ezindaweni eziningi ngebanga lokuzungezisa ngokulawula ingcindezi ezimbobeni.Izindawo zokuma zingaba kunoma ikuphi ukulandelana, okwenza kube nokwenzeka ukuthi i-actuator idlule ngokukhetha ukuma okuphakathi nendawo.
Amabhawodi okumisa ukuhamba
Amabhawodi okumisa ukuhamba asohlangothini lwe-actuator (njengoba kubonakala kuMfanekiso 6) futhi avumela ukulungiswa kwezindawo zokugcina zamaphistoni ngokunciphisa ukujikeleza kwegiya lephini kusuka ngaphakathi.Lapho ufaka i-actuator, shayela ngawo womabili amabhawodi okumisa ukuhamba kuze kube yilapho uthintana nekhephu yokumisa uhambo.Qhubeka ufinya ibhawudi yesitobhi sohambo esingakwesokunxele kuze kube yilapho isikhala sephinikhodi esibonakala phezulu sizungeza siye endaweni ehambisana nobude bomzimba we-actuator.
Isicelo somkhiqizo: ingxenye vula i-actuator kagesi
Ngenxa yokuphuma kwawo njalo kwetorque,Ama-Rack nama-pinion actuatorsasetshenziswa njalo futhi ngokuvamile isitayela esithandwayo sama-actuator womoya wamavalvu.Asetshenziselwa ukuxuba, ukulahla, ukuphakela ngezikhathi ezithile, ukuzungeza okuqhubekayo, ukuphenduka, ukubeka indawo, ukugoqa, ukuphakamisa, ukuvula nokuvala nokuphenduka.Lawa ma-actuator asetshenziselwa imisebenzi eyahlukene yemishini embonini yensimbi, ukuphatha izinto ezibonakalayo, ukusebenza olwandle, okokusebenza kokwakha, imishini yezimayini, kanye neziqondiso zamandla we-hydraulic.
