I-Compressor ye-MAZ

Hlola ukushuba kwebhande le-compressor drive nsuku zonke. I-strap kufanele yelulwe ukuze uma ucindezela phakathi kwegatsha elifushane le-strap ngamandla angama-3 kg, ukuphambuka kwawo kungu-5-8 mm. Uma ibhande liguquguquka ngaphezulu noma ngaphansi kwevelu eshiwo, lungisa ukushuba kwalo, njengoba ngaphansi noma ngaphezulu kokungezwani kungaholela ekugugeni ngaphambi kwesikhathi kwebhande.

Inqubo yokusetha imi kanje:

• khulula nati le-tensioner pulley shaft nenati lebhawodi eliqinisayo;
• ukuguqula i-tensioner bolt ngokwewashi, lungisa ukushuba kwebhande;
• qinisa amantongomane ubambe i-asi yebhawodi ye-tensioner.

Ingqikithi yokusetshenziswa kukawoyela kwe-compressor incike ekuthembekeni kokuvalwa kwesiteshi sikawoyela esisesembozweni sangemuva se-compressor. Ngakho-ke, ngezikhathi ezithile ngemuva kwe-10-000 km yemoto, susa isembozo sangemuva bese uhlola ukuthembeka kophawu.

Uma kunesidingo, izingxenye zedivayisi yokuvala zigezwa ngamafutha edizili futhi zihlanzwe kahle ngamafutha e-coke.

Ngemuva kokusebenza kuka-40-000 km, susa ikhanda le-compressor, ama-piston ahlanzekile, ama-valve, izihlalo, iziphethu kanye namaphaseji omoya avela kumadiphozithi e-carbon, khipha futhi ukhiphe ipayipi lokudonsa. Ngesikhathi esifanayo hlola isimo se-unloader kanye nokuqina kwama-valve. Ama-valve agqokiwe angavaleli izihlalo, futhi uma lokhu kwehluleka, faka amasha esikhundleni sawo. Ama-valve amasha nawo kufanele ahlanganiswe.

Lapho uhlola isilayishi, qaphela ukunyakaza kwama-plunger ezihlahleni, okumele zibuyele endaweni yazo yasekuqaleni ngaphandle kokubopha ngaphansi kwesenzo semithombo. Kudingeka futhi ukuhlola ukucinana kokuxhumana phakathi kwe-plunger ne-bushing. Isizathu sokungaqini okwanele kungase kube indandatho ye-raber piston egugile, okumele ishintshwe kulokhu entsha.

Uma uhlola futhi ushintsha izindandatho, ungasusi ikhanda le-compressor, kodwa susa ipayipi lokuhambisa umoya, susa ingalo ye-rocker kanye nentwasahlobo. I-plunger ikhishwa kusokhethi ngehhuku yocingo, efakwa embobeni enobubanzi obungu-2,5 mm etholakala ekugcineni kwe-plunger, noma umoya unikezwa kumzila ovundlile wedivayisi yomjovo.

Gcoba ama-plunger nge-CIATIM-201 GOST 6267-59 amafutha ngaphambi kokuwafaka endaweni.

Ukugeleza okuphelele kwamanzi kusuka ekhanda kanye ne-cylinder block ye-compressor kwenziwa nge-valve ye-valve etholakala edolweni lepayipi le-compressor outlet. Uma ukungqongqoza kwenzeka ku-compressor ngenxa yokwanda kwegebe phakathi kwamabheringi enduku yokuxhuma kanye namajenali e-crankshaft, buyisela amabhering enduku yokuxhuma i-compressor.

Uma i-compressor inganikeli ukucindezela okudingekayo ohlelweni, okokuqala hlola isimo samapayipi nokuxhumeka kwawo, kanye nokuqina kwama-valve kanye nomlawuli wokucindezela. Ukuqina kuhlolwa indlebe noma, uma ukuvuza komoya kukuncane, ngesisombululo sensipho. Izimbangela ezingaba zokuvuza komoya kungase kube ukuvuza kwe-diaphragm, okuzobonakala ngoxhumo olunentambo engxenyeni engenhla yomzimba noma ngembobo engxenyeni engezansi yomzimba uma ivalvu ingaqinile. Shintsha izingxenye ezivuzayo.

Idivayisi ye-compressor ye-MAZ

I-compressor (Umfanekiso we-102) iyi-piston yamasilinda amabili eqhutshwa i-V-belt kusukela ku-pulley fan. Ikhanda le-cylinder kanye ne-crankcase kuboshwe ku-cylinder block, futhi i-crankcase iboshelwa enjinini. Engxenyeni emaphakathi ye-cylinder block kukhona i-cavity lapho i-compressor unloader ikhona.

Ilayisi. 102.MAZ Compressor:

I-1 - ipulaki yokuthutha ye-crankcase ye-compressor; 2 - i-compressor crankcase; 3 no-11 - ama-bearings; 4 - ikhava yangaphambili ye-compressor; 5 - ibhokisi lokugxusha; 6 - isikhwama; 7 - i-compressor cylinder block; 8 - i-piston enenduku yokuxhuma; 9 - inhloko ye-block of cylinders ye-compressor; 10 - indandatho yokugcina; I-12 - i-thrust nut; I-13 - isembozo sangemuva se-crankcase ye-compressor; 14 - sealant; 15 - uphawu lwentwasahlobo; 16 - crankshaft; 17 - i-valve yokungena entwasahlobo; 18 - i-valve yokungena; 19 - umhlahlandlela we-valve wokungena; 20 - i-rocker arm guide spring; 21 - intwasahlobo ye-rocker; 22 - isiqu se-valve yokungena; 23 - i-rocker; 24 - plunger; 25 - indandatho yokuvala

I-compressor lubrication system ixubile. Amafutha ahlinzekwa ngaphansi kwengcindezi esuka kulayini kawoyela wenjini ukuya kumabhering wenduku yokuxhuma. Amafutha ageleza avela ezindongeni zokuxhuma afafazwa, aphenduke abe yinkungu yamafutha futhi agcobe isibuko se-cylinder.

Isipholile esicindezelayo sigeleza epayipini sisuka ohlelweni lokupholisa injini siye kusilinda, sisuka lapho siye ekhanda lesilinda bese sikhishelwa emgodini wokumunca wepompo lamanzi.

Umoya ongena ku-compressor ungena ngaphansi kwama-valve e-reed inlet 18 atholakala ku-cylinder block. Ama-valve okungena abekwe ku-guide 19, okunciphisa ukugudluka kwawo okuhlangene. Ukusuka phezulu, ama-valve acindezelwa ngokumelene nesihlalo ngesiphethu se-valve yokungenisa. Ukuya phezulu kwe-valve kunqunyelwe induku yomhlahlandlela wasentwasahlobo.

Njengoba i-piston ihamba phansi, kwakhiwa i-vacuum kusilinda ngaphezu kwayo. Isiteshi sixhumana nesikhala esingenhla kwepiston ngesikhala esingaphezu kwevalvu yokudonsa. Ngakho-ke, umoya ongena ku-compressor unqoba amandla asentwasahlobo we-valve yokungenisa 17, uyawuphakamisa futhi ugijimele ku-cylinder ngemuva kwepiston. Lapho i-piston ihambela phezulu, umoya uyacindezelwa, unqobe amandla e-valve yokusetha kabusha isiphethu, uyikhiphe esihlalweni bese ungena emigodini eyakhiwe kusukela ekhanda ngokusebenzisa imibhobho ohlelweni lwe-pneumatic yemoto.

Ukukhipha i-compressor ngokudlula umoya ngama-valve e-inlet avulekile kwenziwa kanje.

Uma ukucindezela okukhulu kwe-7-7,5 kg / cm2 kufinyelelwa ohlelweni lwe-pneumatic, isilawuli sokucindezela sicushiwe, esidlulisa kanyekanye umoya ocindezelwe esiteshini esivundlile se-unloader.

Ngaphansi kwesenzo sokucindezela okwenyukayo, ama-pistons 24 kanye nezinduku 22 akhuphuka, anqobe ukucindezela kwemithombo yama-valve okuphuza, kanye nezingalo ze-rocker 23 ngesikhathi esisodwa ziklebhula womabili ama-valve okungena esihlalweni. Umoya ugeleza usuka kwesinye isilinda uye kwenye ungene ezikhaleni ezakhiwe eziteshini, lapho kumiswa khona ukunikezwa komoya ocindezelwe ohlelweni lwe-pneumatic yemoto.

Ngemuva kokunciphisa ukucindezela komoya ohlelweni, ingcindezi yayo esiteshini esivundlile esixhunywe nesilawuli sokucindezela siyehla, ama-plunger kanye nezinduku zokuthulula ziyancipha ngaphansi kwesenzo seziphethu, ama-valve okungena ahlala ezihlalweni zawo, futhi inqubo yokuphoqa umoya ungene. uhlelo lwe-pneumatic luyaphindwa futhi.

Isikhathi esiningi, i-compressor igijima ingalayishiwe, idonsa umoya usuka kwelinye isilinda ukuya kwelinye. Umoya ujovwa ohlelweni lwe-pneumatic kuphela lapho ingcindezi yehla ngaphansi kuka-6,5-6,8 kg/cm2. Lokhu kuqinisekisa ukuthi ukucindezela ohlelweni lwe-pneumatic kunqunyelwe futhi kunciphisa ukugqoka ezingxenyeni ze-compressor.
