Mugomo modhi, nhanho yekuburitswa kwemabhureki inogoneka, iyo isiri iyo yakazara yekudurura mabhureki cylinders. Iyi modhi inoshandiswa paunenge uchityaira pane yakaoma mbiri ine mutsetse wakakura.

Iyo 483 air distributor chishandiso chinonakidza kwazvo. Ongororo yakadzama yemagadzirirwo ayo uye kushanda kwayo inyaya yechinyorwa chakakura chakasiyana. Pano takatarisa mitemo yakawanda yekushanda kwebrake yekutakura.

3. Pasenger type air brakes

Braking midziyo yemotokari inotakura: 1 - hose yekubatanidza; 2 - vharafu yekupedzisira; 3, 5 - junction mabhokisi e electropneumatic brake line; 4 - vharafu yekumisa; 6 - chubhu ine wiring ye electropneumatic brake; 7 - insulated kumiswa kwehose yekubatanidza; 8 - muunganidzi weguruva; 9 - bazi kumugovera wemhepo; 10 - kuparadzanisa valve; 11 - kamuri yekushanda yemugovera wemhepo yemagetsi; TM - brake line; VR - muparidzi wemhepo; EVR - muparidzi wemhepo yemagetsi; TC - bhureki humburumbira; ZR - tangi yakasara

Ziso rinobva rabatwa nehuwandu hwemidziyo, kutanga nenyaya yekuti kune akawanda anosvika matatu ekumisa mavharuvhu ekukurumidzira (rimwe muvheti rega rega, uye rimwe riri mukamuri ye conductor), zvichiguma nenyaya yekuti mota dzepamusha dzinotakura vanhu dzakashongedzerwa zvese zviri zviviri pneumatic uye. electropneumatic brake (EPT).

Muverengi anoteerera anobva aona iyo huru yekudzosa yepneumatic brake control - iyo yekupedzisira kumhanya kweiyo brake wave, yakaganhurwa kubva kumusoro nekumhanya kwekurira. Mukuita, iyi kumhanya yakaderera uye 280 m / s yebasa, uye 300 m / s yekukurumidzira braking. Mukuwedzera, iyi kukurumidza kunonyanya kuenderana nekupisa kwemhepo uye munguva yechando, somuenzaniso, yakaderera. Naizvozvo, mufambidzani wekusingaperi wepneumatic mabhureki ndiko kusaenzana kwekushanda kwavo mukuumbwa.

Kusaenzana kushanda kunotungamira kuzvinhu zviviri - kuitika kweakakosha longitudinal reactions muchitima, pamwe nekuwedzera kweiyo braking chinhambwe. Yekutanga haina kufanana kune zvitima zvinotakura vanhu, kunyangwe midziyo ine tii nezvimwe zvinwiwa zvinosvetuka patafura mukamuri hazvifadze chero munhu. Kuwedzera kwemabhureki idambudziko rakakura, kunyanya mukufambiswa kwevanhu.

Mukuwedzera, mutakuri wemufambi wemhepo muparadzi - zvose zvekare mamiriro No. 292, uye mamiriro matsva No. Ivo vanosiyana nevhavhavhavha katatu nekuvapo kweiyo inopindirana modhi, ndiko kuti, mukana wenhanho braking; kuvapo kwekuwedzera kubudiswa kwemutsara wekuputika panguva yekuputika; kuvapo kwechimbichimbi braking accelerator mukugadzira. Ava vaparadzi vemhepo havapi danho rekusunungurwa - vanobva vangopa kusunungurwa kwakazara nekukurumidza kana kudzvinyirirwa mumutsara webhureki kunopfuura kumanikidzwa mutangi rekuchengetedza, rakasimbiswa ipapo mushure mekuputika. Uye kuburitswa kwenhanho kunobatsira kwazvo pakugadzirisa braking kuti inyatsomira papuratifomu yekumhara.

Matambudziko ese ari maviri - asina kuenzana mabhureki mhinduro uye kushomeka kwekuburitswa kwenhanho - anogadziriswa pane 1520 mm track nekuisa magetsi anodzorwa nemhepo anoparadzira pamotokari. electric air distributor (EVR), mamiriro nhamba 305.

Domestic EPT - electropneumatic brake - yakananga-kuita, isiri-otomatiki. Pazvitima zvinotakura vanhu zvine locomotive traction, EPT inoshanda pawaya mbiri.

Chimiro chechimiro cheEPT-waya mbiri: 1 - mutongi pane crane yemutyairi; 2 - bhatiri rekuchengetedza; 3 - static simba converter; 4 - chigadziko chemwenje; 5 - control unit; 6 - terminal block; 7 - kubatanidza misoro pamaoko; 8 - insulated kuturika; 9 - semiconductor vharafu; 10 - kusunungura electromagnetic valve; 11 - brake electromagnetic valve.

Waya mbiri dzakatambanudzwa pamwe chete nechitima chose: Nhamba 1 uye Nha. Pamotokari yemuswe, waya idzi dzakabatanidzwa nemagetsi kune imwe neimwe uye inochinjana ikozvino ye2 Hz inotumirwa kuburikidza neinobuda loop. Izvi zvinoitirwa kutarisa kuvimbika kweiyo EPT control line. Kana waya inoputika, iyo inotenderera yedunhu inoputsika, uye mutyairi anogamuchira chiratidzo muchimiro chemwenje wekudzora "O" (kusunungurwa) ichibuda mukamuri.

Kudzora kunoitwa neakananga ikozvino ye polarity yakasiyana. Muchiitiko ichi, waya ine zero inogoneka ndiyo njanji. Kana magetsi akanaka (anoenderana nenjanji) akaiswa kune EAD waya, ese emagetsi mavharuvhu akaiswa mumagetsi emhepo distributor anotangwa: kuburitswa (OV) uye brake (TV). Yokutanga yadzo inotsaura kamuri yekushanda (WC) yemagetsi mhepo distributor kubva mumhepo, yechipiri inozadza iyo kubva kune yekuchengetedza tangi. Ipapo iyo yekumanikidza relay yakaiswa muEAD inosvika pakutamba, ichishanda pamusiyano wekumanikidza mukamuri yekushanda uye silinda yebhureki. Kana kudzvinyirirwa muWC kuchipfuura kudzvanywa muTC, iyo yekupedzisira inozadzwa nemhepo kubva mutangi rekuchengetedza, kusvika kune kumanikidzwa kwakaunganidzwa muimba yekushanda.

Kana simba risina kunaka rinoshandiswa kune waya, vheji yebhureki inodzimwa, sezvo ikozvino kune iyo inogurwa ne diode. Ivhavha yekusunungura chete, iyo inochengetedza kudzvinyirira muimba yekushanda, inoramba ichishanda. Iyi ndiyo nzira iyo nzvimbo yekupindirana inowanikwa.

Kana iyo voltage ichibviswa, valve yekuburitsa inorasikirwa nesimba, ichivhura kamuri yekushanda kumhepo. Kana dzvinyiriro iri mukamuri yekushanda yadzikira, kudzokedzana kunoburitsa mweya kubva mumabhureki cylinders. Kana, mushure mekusunungurwa kwenguva pfupi, vheji yemutyairi inoiswa zvakare panzvimbo yepamusoro, kudonha kwekumanikidzwa muimba yekushanda kuchamira, uye kusunungurwa kwemhepo kubva muvhareki cylinder kuchamirawo. Nenzira iyi, mukana wekubuda kwebhureki nhanho unowanikwa.

Chii chinoitika kana waya ikadambuka? Ndizvozvo - iyo EPT ichasunungura. Naizvozvo, iyi bhureki (padzimba yekutenderedza stock) haina otomatiki. Kana EPT ikakundikana, mutyairi ane sarudzo yekuchinja kune pneumatic brake control.

Iyo EPT inosiyaniswa nekuzadza panguva imwe chete yemabrake cylinders uye kubuda kwavo muchitima. Chiyero chekuzadza uye kubvisa chakanyanya kukwirira - 0,1 MPa pasekondi. Iyo EPT ibhureki risingaperi, sezvo panguva yekushanda kwayo, iyo yakajairwa mhepo muparadzi iri munzira yekuburitsa uye inodyisa matangi akasara kubva pamutsetse webhureki, iyo inopihwawo nevhavha yekutyaira pane locomotive kubva kumatangi makuru. Naizvozvo, iyo EPT inogona kubhureki chero frequency inodiwa yekushanda mabhureki control. Iko mukana wekuburitsa nhanho inobvumidza iwe kudzora kumhanya kwechitima zvakanyatsorongeka uye zvakanaka.

Kudzora kwepneumatic kwemabhureki echitima chinotakura vanhu hakuna kunyanya kusiyana nemabhureki ekutakura zvinhu. Pane mutsauko munzira dzekudzora, semuenzaniso, kuburitswa kwepneumatic brake kunoitwa kune yekuchaja kudzvanywa, pasina kudzvinyirira zvakanyanya. Muzhinji, kudzvinyirira zvakanyanya mumutsara webhureki wechitima chevafambi kuzere nedambudziko, saka, kana EPT yaburitswa zvachose, kudzvanywa muTM kunonyanya kudzvinyirirwa nehupamhi hwe0,02 MPa pamusoro pekukosha kweiyo set yekuchaja kudzvanywa.

Iko kudzika kudzika kweTM kuburitswa panguva yekubhureki pamutakuri mabhureki ndeye 0,04 - 0,05 MPa, nepo kudzvanywa mumasilinda emabhureki kuri 0,1 - 0,15 MPa. Iyo yakanyanya kudzvanywa mubhureki cylinder yemotokari yevafambi inoganhurwa nehuwandu hwenzvimbo yekuchengetedza uye kazhinji haipfuure 0,4 MPa.
