Ivalve yokulawula ukuhamba kwekhatriji yekhatriji LFR10-2A-K

Ivalve yembuyekezo yoxinzelelo

Ngokwendawo yevalve yembuyekezo yoxinzelelo kuyo yonke isekethe ye-hydraulic, inkqubo yokulawula imbuyekezo yoxinzelelo lomthwalo inokwahlulwa ibe yinkqubo yembuyekezo yembuyekezo ye-valve yangaphambili kunye nenkqubo yembuyekezo yembuyekezo ye-post-valve. Imbuyekezo yangaphambi kwevalvu ithetha ukuba ivalve yembuyekezo yoxinzelelo icwangciswe phakathi kwempompo yeoli kunye nevalve yokulawula, kwaye imbuyekezo yangemva kwevalvu ithetha ukuba ivalve yembuyekezo yoxinzelelo icwangciswe phakathi kwevalve yokulawula kunye ne-actuator. Imbuyekezo yasemva kwevalvu ihambele phambili kakhulu kunembuyekezo yangaphambi kwevalvu, ngakumbi kwimeko yokungonelanga kweoyile yempompo. Ukuba ukunikezelwa kweoyile yempompo akwanelanga, i-valve engundoqo ihlawulwe phambi kokuba i-valve iya kubangela ukuhamba okungaphezulu kumthwalo wokukhanya kunye nokuhamba okuncinci kumthwalo onzima, oko kukuthi, umthwalo okhanyayo uhamba ngokukhawuleza, kwaye i-actuator nganye iphuma kwi-sync. xa intshukumo edibeneyo yenziwe. Nangona kunjalo, imbuyekezo ye-valve emva kwe-valve ayinayo le ngxaki, iya kusasaza ukuhamba okunikezelwe yimpompo ngokulinganayo, kwaye ivumelanise zonke izinto ezisebenzayo ngexesha lesenzo se-compound. Inkqubo yokuva umthwalo wohlulwe kwimbuyekezo yangaphambi kwevalvu kunye nembuyekezo yasemva kwevalvu. Xa imithwalo emibini okanye ngaphezulu isebenza ngexesha elifanayo, ukuba ukuhamba okunikezelwe yimpompo engundoqo kwanele ukuhlangabezana nokuhamba okufunwa yinkqubo, imisebenzi yembuyekezo ye-valve yangaphambili kunye nembuyekezo ye-post-valve ifana ngqo. Ukuba ukuhamba okunikezelwe yimpompo ephambili akukwazi ukuhlangabezana nokuhamba okufunwa yinkqubo, imbuyekezo phambi kwevalve ngolu hlobo lulandelayo: ukuhamba kompompo oyintloko kuqala kubonelela ukuhamba kumthwalo ngomthwalo omncinci, kwaye emva koko unikezela ukuhamba. kweminye imithwalo xa iimfuno zokuhamba komthwalo onomthwalo omncinci zidibene; Imeko yembuyekezo ye-post-valve yile: ukunciphisa ukuhamba kokuhamba komthwalo ngamnye xa kuthelekiswa nexesha elifanayo lonyaka ophelileyo (ukuvulwa kwevalve) ukuphumeza umphumo wesenzo esilungelelanisiweyo. Oko kukuthi, xa ukuhamba okunikezelwe yimpompo engundoqo kungenakuhlangabezana nokuhamba okufunwa yinkqubo, ukusabalalisa ukuhamba kuhlawulwe ngaphambi kokuba i-valve ihambelane nomthwalo, ngelixa ukuhanjiswa kokuhamba kuhlawulelwe emva kokuba i-valve ingahambelani nomthwalo, kodwa kuphela. enxulumene nesixa sokuvula sevalve ephambili.
