Chimiro chinoratidza chimiro cheichi bhureki (Mufananidzo a - kushanda kwebhureki panguva yekuburitswa; b - kushanda kwebhureki panguva yekubhureki). Chinhu chikuru cheWestigauze brake yaive brake air distributor kana, sezvazvinombonzi dzimwe nguva, vharafu katatu. Uyu muparadzi wemhepo (6) ane nhengo inonzwisa tsitsi - piston inoshanda pamusiyano uri pakati pematsimba maviri - mumutsara webhureki (TM) uye reservoir reservoir (R). Kana dzvinyiriro muTM ikava shoma pane muTC, ipapo piston inoenda kuruboshwe, ichivhura nzira yemhepo kubva kuCM kuenda kuTC. Kana dzvinyiriro iri muTM ikava yakakura kudarika kumanikidzwa muSZ, piston inofamba ichienda kurudyi, ichitaurirana neTC nemhepo, uye panguva imwechete ichikurukura TM neSZ, zvichiita kuti iyo yekupedzisira izere nemhepo yakamanikidzwa kubva. iye TM.
Saka, kana kudzvinyirirwa muTM kuchiderera nokuda kwechikonzero chipi nechipi, zvingava zviito zvemutyairi, kubuda kwemhepo yakanyanyisa kubva kuTM, kana kuputika kwechitima, mabhureki achashanda. Kureva kuti mabhureki akadaro ane otomatiki chiito. Ichi chivakwa chebhureki chakaita kuti zvikwanise kuwedzera imwe mukana wekudzora mabhureki echitima, ayo anoshandiswa pazvitima zvinotakura vanhu kusvika nhasi - kumira kwechitima nechitima nemutyairi nekutaurirana mutsara webhureki nemhepo kuburikidza nevhavha yakakosha - emergency brake (9).
Kune avo vanoziva nezvechikamu ichi chemabhureki echitima, zvinosetsa kuona mafirimu apo mbavha-vakomana vemombe vanokurura zvine mutsindo ngoro ine goridhe kubva muchitima. Kuti izvi zviitike, vafudzi vemombe vanofanira, vasati vasangana, vavhare mavharuvhu ekupedzisira pamutsara webhureki unoparadzanisa mutsara webhureki kubva pamagetsi ekubatanidza pakati pemotokari. Asi havambodaro. Kune rumwe rutivi, mavharuvhu ekupedzisira akavharwa ane kanopfuura kamwechete akakonzera njodzi dzinotyisa dzine chokuita nekukundikana kwemabhureki, zvose pano (Kamensk muna 1987, Eral-Simskaya muna 2011) uye kunze kwenyika.
Nekuda kwekuti kuzadza kwemasilinda mabhureki kunoitika kubva kune yechipiri sosi yemhepo yakamanikidzwa (spare tank), pasina mukana wekugara ichizadzikiswa, brake yakadai inonzi. kuita zvisina kunanga. Kuchaja kwebhureki nemhepo yakatsikirirwa kunoitika chete kana bhureki raburitswa, izvo zvinotungamira kune chokwadi chekuti nekugadzika braking kunoteverwa nekuburitswa, kana pasina nguva yakakwana mushure mekusunungurwa, bhureki harizove nenguva yekuchaja kune inodiwa kudzvanywa. Izvi zvinogona kukonzera kuneta kwakakwana kwebhureki uye kurasikirwa kwekudzora mabhureki echitima.
Iyo pneumatic brake inewo imwe dhizaini ine chekuita nekuti kudonhedza kudonha mumutsara webhureki, senge kukanganisa kupi, kunopararira mumhepo kumusoro, asi kuchiri kupera, kumhanya - kwete kupfuura 340 m / s. Nei zvisingawedzere? Nekuti kumhanya kweruzha kwakanakira. Asi muchitima chepneumatic system pane zvipingamupinyi zvakawanda zvinoderedza kukurumidza kwekupararira kwekudonhedzwa kwekumanikidzwa kunobatanidza nekupikisa kuyerera kwemhepo. Naizvozvo, kunze kwekunge matanho akakosha akatorwa, chiyero chekudzikiswa kwedziviriro muTM ichave yakaderera, iyo inoenderera mberi mota ichibva kune locomotive. Panyaya yeWestinghouse bhureki, kumhanya kweanonzi braking wave haipfuuri 180 - 200 m / s.
Zvisinei, kuuya kwebhureki repneumatic kwakaita kuti zvikwanisike kuwedzera simba remabhureki uye kushanda nesimba kwekutonga kwawo kubva kunzvimbo yebasa yemutyairi.Izvi zvakashanda sesimba guru rekusimudzira kutakura njanji, zvichiwedzera kukurumidza uye huremu hwemotokari. zvitima, uye somugumisiro, kuwedzera kukuru kwekutakura zvinhu panjanji, kuwedzera kwehurefu hwenjanji pasi rose.
George Westinghouse akanga asiri muvambi chete, asiwo muzvinabhizimisi aishingaira. Akapa patent yekugadzirwa kwake muna 1869, izvo zvakamubvumira kuti atange kugadzirwa kwemazhinji emidziyo yebhureki. Nekukurumidza, mabhureki eWestinghouse akapararira muUSA, Western Europe uye Humambo hweRussia.
MuRussia, mabhureki eWestinghouse akatonga kusvika muna Gumiguru Revolution, uye kwenguva yakareba mushure mayo. Kambani yeWestinghouse yakagadzira bhureki yayo pachayo muSt. Nekudaro, iyo Westinghouse brake yaive nezvakawanda zvisizvo zvakakosha.
Chekutanga, bhureki iri rakapa maitiro maviri chete ekushandisa: braking kusvikira masilinda akabhureka azadzwa zvachose, uye holide — kubvisa ma cylinders emabhureki. Zvakanga zvisingaite kugadzira huwandu hwepakati hwekumanikidzwa kwebhureki nekugadzirisa kwayo kwenguva refu, ndiko kuti, iyo Westinghouse brake yakanga isina modhi. reroof. Izvi hazvina kubvumira kunyatso kudzora kumhanya kwechitima.
Chechipiri, mabhureki eWestinghouse haana kushanda zvakanaka pazvitima zvirefu, uye nepo izvi zvaigona kuregererwa mumigwagwa yevafambi, matambudziko akamuka mumigwagwa yekutakura zvinhu. Rangarira mabhureki wave? Saka, mabhureki eWestinghouse akange asina nzira yekuwedzera kumhanya kwayo, uye muchitima chakareba, kuderera kwekumanikidzwa kwebhureki fluid pamotokari yekupedzisira kunogona kutanga kunonoka, uye pamwero wakaderera zvakanyanya kupfuura kumusoro kweiyo. chitima, izvo zvakagadzira kusaenzana kusashanda kwemabhureki muchitima.
Zvinofanira kutaurwa kuti mabasa ese ekambani yeWestinghouse, muRussia panguva iyoyo uye pasi rese, akanyatsozadzwa nekunhuhwirira kwecapitalist yehondo dzepatent uye kukwikwidza kusina kunaka. Izvi ndizvo zvakaita kuti gadziriro yakadaro isina kukwana irarame upenyu hwakareba kudaro, kunyanya munguva iyoyo yenhau.
Nezvese izvi, zvinofanirwa kucherechedzwa kuti iyo Westinghouse brake yakateya nheyo dze braking sainzi uye musimboti wekushanda kwayo wakaramba usina kuchinjika mune ano rolling stock mabhureki.
2. Kubva kuWestinghouse bhureki kuenda kuMatrosov brake - kuumbwa kwesainzi yekubhureki yemumba.
Anenge pakarepo mushure mekuonekwa kweWestinghouse brake uye kuitika kwezvikanganiso zvayo, kuedza kwakamuka kuvandudza iyi hurongwa, kana kuumba imwe, itsva. Nyika yedu yakange isina mutsauko. Mukutanga kwezana remakore rechiXNUMX, Russia yakanga ine network yakagadziridzwa yenjanji, iyo yakaita basa rinokosha mukuchengetedza hupfumi uye kukwanisa kudzivirira nyika.
