Amashanyarazi yububiko nubwubatsi burambuye amakuru yumuriro wamashanyarazi nibyiza bya pneumatike nibibi byo kugereranya

Amashanyarazi yububiko nubwubatsi burambuye ibisobanuro byumuriro wamashanyarazi nibyiza bya pneumatike nibibi byo kugereranya Ikibanza cyibikorwa byamashanyarazi nini nini kuruta icyuma gisanzwe, umuvuduko wibikorwa byumuvuduko wamashanyarazi urashobora guhinduka, imiterere yoroshye, byoroshye kubungabunga, inzira yibikorwa kuko ya buffer iranga gaze ubwayo, ntabwo byoroshye kwangizwa no gufunga, ariko igomba kuba ifite isoko yumwuka, kandi sisitemu yo kugenzura iraruhije kuruta amashanyarazi. Ubu bwoko bwa valve bugomba gushyirwaho muburyo butambitse. Umuyoboro w'amashanyarazi ubusanzwe ugizwe na moteri ikora na valve. Umuyagankuba ukoresha ingufu zamashanyarazi nkimbaraga zo gutwara valve unyuze mumashanyarazi kugirango umenye ibikorwa bya valve. Kugirango rero ugere ku ntego yo guhindura imiyoboro iciriritse. None, ni ubuhe buryo burambuye twakagombye kwitondera mugikorwa cyo kwishyiriraho amashanyarazi? Igikoresho cyamashanyarazi nigikoresho cyingirakamaro kugirango tumenye gahunda ya valve, kugenzura byikora no kugenzura kure. Igikorwa cyacyo gishobora kugenzurwa na stroke, torque cyangwa ubunini bwa axial. Kuberako ibiranga akazi nigipimo cyikoreshwa ryigikoresho cyamashanyarazi giterwa nubwoko bwa valve, ibisobanuro byakazi byigikoresho hamwe numwanya wa valve mumiyoboro cyangwa ibikoresho, kubwibyo rero, guhitamo neza ibikoresho byamashanyarazi nibyingenzi kuri irinde ibintu birenze urugero (torque ikora irarenze kugenzura umuriro). Mubisanzwe, guhitamo neza ibikoresho byamashanyarazi bishingiye kubi bikurikira: Gukoresha itara rikoresha torque ikora nikintu nyamukuru cyo guhitamo igikoresho cyamashanyarazi. Ibisohoka bisohoka mubikoresho byamashanyarazi bigomba kuba inshuro 1,2 ~ 1.5 yumuriro wa valve ikora tripode. Hano haribintu bibiri byingenzi byububiko bwamashanyarazi ya valve: imwe ntabwo igizwe na disiki ya disiki, isohoka itaziguye; Ibindi ni iboneza rya disiki ya disikuru, ibisohoka bisohoka binyuze muri disiki ya stem stem nut mubisohoka. Umubare wimpeta zizunguruka zisohoka shaft yicyuma cyamashanyarazi gifitanye isano na diameter nominal yikibanza cya valve numubare winsanganyamatsiko. Igomba kubarwa ukurikije M = H / ZS (M numubare wuzuye wimpeta zizunguruka igikoresho cyamashanyarazi kigomba guhazwa, H nuburebure bwugurura bwa valve, S ni ikibanza cyurudodo rwumuti wa valve na Z ni umubare wurudodo rwibiti). Diameter yumuti kumirongo myinshi ifunguye-inkoni, niba diameter nini yumuti yemeranijwe nigikoresho cyamashanyarazi ntishobora kunyura mumashanyarazi, ntishobora guteranyirizwa mumashanyarazi. Kubwibyo, umurambararo wimbere wibisohokayandikiro bisohoka byigikoresho cyamashanyarazi bigomba kuba binini kurenza diametre yinyuma yikibabi cyafunguye-inkoni. Kubirindiro byijimye byijimye mumashami azunguruka hamwe na rot-rotary nyinshi, nubwo bidakenewe gusuzuma diameter yikibiti cya valve, diameter yikibiti cya valve nubunini bwinzira nyamukuru nayo igomba gutekerezwa byuzuye muri guhitamo, kugirango inteko ishobore gukora bisanzwe. Niba gufungura no gufunga umuvuduko wibisohoka byihuta byihuta, biroroshye kubyara amazi percussion phenomenon. Kubwibyo, gufungura no gufunga byihuse bigomba guhitamo ukurikije uburyo butandukanye bwo gukoresha. Kugereranya ibyiza nibibi bya valve yamashanyarazi na pneumatike valve Umuyoboro wamashanyarazi ukoreshwa cyane cyane mumashanyarazi cyangwa mumashanyarazi, kuko sisitemu yamazi yumuvuduko mwinshi bisaba inzira yoroshye, idahungabana kandi itinda. Ibyiza byingenzi byumuriro wamashanyarazi nuko uburebure butarangiritse kandi uyikoresha arashobora gukoresha imbaraga zihoraho. Imbaraga zakozwe na actuator nini zirashobora kugera kuri 225000kgf. Gusa hydraulic actuator irashobora kugera kumurongo munini, ariko ikiguzi cya hydraulic hydraulic kiri hejuru cyane ugereranije nicyuma gikoresha amashanyarazi. Ubushobozi bwo kurwanya gutandukana kwamashanyarazi nibyiza cyane, kandi ibisohoka bisohoka cyangwa torque muri rusange bihoraho, bishobora gutsinda neza imbaraga zitaringanijwe ziciriritse kandi bikagera no kugenzura neza ibipimo byimikorere. Kubwibyo, kugenzura neza birarenze ibyo gukora pneumatike. Niba servo amplifier ikoreshwa, ingaruka nziza nibibi zirashobora guhanahana byoroshye, kandi imyanya yumwanya wo kumena ibimenyetso bya valve irashobora gushirwaho byoroshye (komeza / ufungure / ufunge byuzuye). Iyo ikosa ribaye, rigomba kuguma mumwanya wambere, ibyo ntibishoboka kubikorwa bya pneumatike. Pneumatic actuator igomba gukoresha urutonde rwokwirinda hamwe kugirango ibungabunge imyanya. Ingaruka nyamukuru zikoreshwa mumashanyarazi ni: Imiterere iraruhije, ikunda gutsindwa, kandi kubera ubunini bwayo, ibisabwa bya tekinike kubakozi bashinzwe kubungabunga aho biri ni byinshi; Imikorere ya moteri kubyara ubushyuhe, niba ihinduka ari kenshi, byoroshye gutera moteri gushyuha, kurinda ubushyuhe, ariko kandi byongera kwambara ibikoresho byo kugabanya; Byongeye, imikorere iratinda. Bifata umwanya muremure wo gusohora ikimenyetso kiva mubuyobozi kugeza kumwanya uhuye mugusubiza umuyobozi. Iyi niyo mpamvu itari nziza nkibikorwa bya pneumatike na hydraulic. Umuyoboro ukoreshwa mu kirere Umuyoboro hamwe nuburyo bwo kugenzura imikorere ya valve pneumatic actuator ni imwe yose, kandi ikora ifite ibyiciro bibiri: ubwoko bwa firime nubwoko bwa piston. Gukubita piston ni birebire, bikwiranye nigihe cyo gusaba imbaraga nini; Filime ya stroke ni nto, irashobora gutwara gusa uruti. Kuberako pneumatic actuator ifite ibyiza byuburyo bworoshye, ibisohoka binini, ibikorwa bihamye kandi byizewe, hamwe n’umutekano ndetse n’ibishobora guturika, ifite uburyo bwiza bwo gukora mu ruganda rukora amashanyarazi, inganda z’imiti, gutunganya amavuta n’ibindi bisabwa umutekano. Ibyiza byingenzi byimikorere ya pneumatike: Emera ibimenyetso bya gaze bihoraho, gusohora umurongo woherejwe (nyuma yo kongeramo igikoresho cyo guhindura amashanyarazi / gaze, birashobora kandi kwakira ibimenyetso byamashanyarazi bihoraho), bimwe bifite ibikoresho bya rocker, birashobora gusohora inguni. Ifite imikorere myiza kandi mibi. Umuvuduko wo kugenda ni mwinshi ariko ugenda gahoro uko umutwaro wiyongera. Imbaraga zisohoka zijyanye nigitutu cyo gukora. Kwizerwa cyane, ariko valve ntishobora kubungabungwa nyuma yo gutanga ikirere gihagaritswe (irashobora gukomeza nyuma yo kongeramo valve igumana). Ntibyoroshye kugera kubigenzura no kugenzura gahunda. Kugenzura no kubungabunga byoroshye, guhuza neza n'ibidukikije. Imbaraga zisohoka nini. Nibikorwa biturika.
