I-compressors yazo zonke iimodeli zinikezelwa kwiindlela ezahlukeneyo zokucwangciswa - kunye nangaphandle kweepulleys, kunye nokukhulula (kunye nomlawuli woxinzelelo lomatshini, "ijoni") kwaye ngaphandle kwayo, njl.
Uyilo kunye nomgaqo wokusebenza kwe-MAZ compressors
I-MAZ compressors yazo zonke iimodeli zinesixhobo esilula.Isiseko seyunithi yibhloko ye-cylinder, kwindawo ephezulu apho iisilinda zikhona, kwaye kwindawo engezantsi kukho i-crankshaft kunye neebheringi zayo.I-crankcase yeyunithi ivaliwe kunye nezikhuselo zangaphambili nangemuva, intloko ifakwe kwibhloko nge-gasket (i-gaskets).Kwiisilinda kukho iipiston kwiintonga zokudibanisa, ukufakwa kwezi nxalenye kuqhutyelwa ngeentambo.I-pulley okanye i-drive gear ifakwe kwinzwane ye-crankshaft, i-pulley / gear ifakwe isitshixo, kunye nokulungiswa ngokuchasene nokufuduka kwexesha elide kunye ne-nut.
Ibhloko kunye ne-crankshaft zinemijelo yeoli ehambisa ioli kwiindawo zokuxubha.Ioyile ecinezelekileyo iqukuqela kwimijelo ekwi-crankshaft ukuya kwiijenali zentonga yokudibanisa, apho ithambisa imiphezulu yojongano lweliners kunye nentonga yokudibanisa.Kwakhona, uxinzelelo oluncinci oluvela kwiijenali zentonga yokudibanisa ngokusebenzisa intonga yokudibanisa ingena kwipiston yepiston.Ukuqhubela phambili, i-oyile ikhupha kwaye iqhekezwe ngamacandelo ajikelezayo abe ngamaconsi amancinci - inkungu ye-oyile ebangelwayo ithambisa iindonga ze-cylinder kunye nezinye iindawo.
Kwintloko yebhloko kukho iivalve - ukungena, apho umoya ovela emoyeni ungena kwi-cylinder, kunye nokukhutshwa, apho umoya oxinyiweyo unikezelwa kwiiyunithi ezilandelayo zenkqubo.Iivalve zine-wafer-shaped, zigcinwe kwindawo evaliweyo ngoncedo lwemithombo edibeneyo.Phakathi kwee-valve kukho isixhobo sokukhulula, apho, xa uxinzelelo kwi-compressor outlet lukhuphuka ngokugqithiseleyo, luvula zombini iivalve, ukuvumela ukuhamba komoya okhululekile phakathi kwabo ngokusebenzisa umjelo wokukhupha.
Uyilo lwe-compressor ye-cylinder ezimbini ze-MAZ
Umgaqo wokusebenza kwee-compressors zomoya ulula.Xa i-injini iqala, i-shaft yeyunithi iqala ukujikeleza, inika ukunyakaza okuphindaphindiweyo kweepiston ngokusebenzisa iintonga zokudibanisa.Xa i-piston ithotywa phantsi kwefuthe loxinzelelo lwe-atmospheric, i-valve yokungena ivula, kwaye umoya ovela, emva kokudlula kwisihlunu ukususa ukungcola, uzalise i-cylinder.Xa i-piston iphakanyisiwe, i-valve yokungena ivala, ngexesha elifanayo i-valve yokukhupha ivaliwe - uxinzelelo ngaphakathi kwe-cylinder luyanda.Xa uxinzelelo oluthile lufikelelwe, i-valve yokukhupha iyavula kwaye umoya ugeleza kuyo kwi-pneumatic system.Ukuba uxinzelelo kwinkqubo luphezulu kakhulu, ke isixhobo sokukhupha siza kusebenza, zombini iivalve zivulekile, kunye ne-compressor idles.
Kwiiyunithi ezimbini ze-cylinder, iisilinda zisebenza kwi-antiphase: xa i-piston enye ihla kwaye umoya ufunxelwa kwi-cylinder, i-piston yesibini ihambela phezulu kwaye iqhube umoya oxinyiweyo kwinkqubo.
Imiba yokugcinwa, ukulungiswa, ukhetho kunye nokutshintshwa kwe-MAZ compressors
I-compressor yomoya yiyunithi elula kwaye ethembekileyo enokusebenza iminyaka.Nangona kunjalo, ukufezekisa esi siphumo, kuyimfuneko ukwenza rhoqo ukugcinwa okumiselweyo.Ngokukodwa, ukunyanzeliswa kwebhanti yokuqhuba i-compressor ye-cylinder ezimbini kufuneka kuhlolwe imihla ngemihla (ukuphambuka kwebhanti akufuneki kudlule i-5-8 mm xa kusetyenziswe amandla angama-3 kg), kwaye, ukuba kuyimfuneko, ukulungiswa kufuneka. mazenziwe kusetyenziswa ibholithi yetensioner.
Yonke i-10-12 yeekhilomitha eziliwaka lokubaleka, kufuneka ukhangele itywina lomjelo wokubonelela ngeoyile kwisikhuselo sangasemva seyunithi.Yonke i-40-50 yeekhilomitha eziliwaka lokubaleka, intloko kufuneka ihlanjululwe, kufuneka ihlambuluke, iipiston, iivalve, iziteshi, ukubonelela kunye ne-outlet hoses, kunye nezinye iindawo.Ukuthembeka kunye nokuthembeka kwee-valve zihlolwe ngokukhawuleza, ukuba kuyimfuneko, zitshintshwe (kunye ne-lapping).Kwakhona, isixhobo sokukhulula siphantsi kokuhlolwa.Wonke umsebenzi kufuneka wenziwe ngokuhambelana nemiyalelo yokugcinwa nokulungiswa kwemoto.
Ukuba iinxalenye zomntu ngamnye we-compressor break, zinokuthi zitshintshwe, kwezinye iimeko kuyimfuneko ukutshintsha ngokupheleleyo i-compressor (i-deformations kunye nokuqhekeka kwentloko kunye nebhloko, ukunxiba ngokubanzi kweesilinda kunye nezinye izinto ezingasebenziyo).Xa ukhetha i-compressor entsha, kuyimfuneko ukuqwalasela imodeli kunye nokuguqulwa kweyunithi endala, kunye nomzekelo weyunithi yamandla.Ngokuqhelekileyo, zonke iiyunithi ezisekelwe kwi-130-3509 zitshintshisana kwaye zinokusebenza kuyo nayiphi na i-YaMZ-236, iinjini ze-238 kunye nokuguqulwa kwazo ezininzi.Nangona kunjalo, kufuneka kukhunjulwe ukuba ezinye zazo zinomthamo we-210 l / min, kwaye ezinye zinomthamo we-270 l / min, kunye ne-compressor entsha yemodeli 5336-3509012 yokuguqulwa okuhlukeneyo ngokuqhelekileyo isebenza ngesantya esiphezulu. .Ukuba i-injini isetyenziselwa ukuba ne-compressor ene-270 l / min, ke iyunithi entsha kufuneka ifane, kungenjalo inkqubo ayiyi kuba nomoya owaneleyo wokusebenza okuqhelekileyo.
I-compressors ye-cylinder eyodwa 18.3509015-10 ibonakaliswe kwinani elincinci lokuguqulwa, kwaye akuzona zonke ezinokuthi zitshintshe.Ngokomzekelo, i-compressor 18.3509015 yenzelwe iinjini ze-KAMAZ 740 kwaye ayifanelekanga kwiinjini ze-YaMZ.Ukuze ugweme iimpazamo, kuyimfuneko ukucacisa amagama apheleleyo e-compressor ngaphambi kokuthenga.
Ngokwahlukileyo, kuyafaneleka ukukhankanya i-compressors yaseJamani i-KNORR-BREMSE, eyi-analogue yale mizekelo ingentla yeeyunithi.Ngokomzekelo, i-compressors ezimbini-cylinder zingatshintshwa yiyunithi 650.3509009, kunye ne-single-cylinder compressors nge-LP-3999.Ezi compressors zineempawu ezifanayo kunye nemilinganiselo yokufakela, ngoko kulula ukuthatha indawo yasekhaya.
Ngokukhetha okufanelekileyo kunye nokufakwa, i-MAZ compressor iya kusebenza ngokuthembekileyo, iqinisekisa ukusebenza kwenkqubo ye-pneumatic yesithuthi kuyo nayiphi na imeko yokusebenza.
