Compressor MAZ

Yang'anani kuthamanga kwa lamba wagalimoto wa compressor tsiku lililonse. Chingwecho chiyenera kutambasulidwa kotero kuti mukamakanikiza pakati pa nthambi yaifupi ya chingwe ndi mphamvu ya 3 kg, kupatuka kwake ndi 5-8 mm. Ngati lambayo amasinthasintha mochuluka kapena mocheperapo kuposa mtengo womwe watchulidwa, sinthani kukhazikika kwake, chifukwa kupsinjika kwapansi kapena kupitilira kungayambitse kuvala msanga kwa lamba.

Kupanga ndondomeko ndi motere:

• masulani mtedza wa shaft wa tensioner ndi bolt wa bolt;
• kutembenuza tensioner bawuti molunjika, sinthani kulimba kwa lamba;
• limbitsani mtedza mutagwira chitsulo cha bawuti.

Kugwiritsa ntchito mafuta konse kwa kompresa kumadalira kudalirika kwa kusindikiza kwa njira yoperekera mafuta pachivundikiro chakumbuyo cha kompresa. Choncho, nthawi ndi nthawi pambuyo pa 10-000 makilomita a galimoto, chotsani chivundikiro chakumbuyo ndikuyang'ana kudalirika kwa chisindikizocho.

Ngati ndi kotheka, mbali za chipangizo chosindikizira zimatsuka mu mafuta a dizilo ndikutsukidwa bwino ndi mafuta a coke.

Pambuyo pa 40-000 km yogwira ntchito, chotsani mutu wa compressor, pistoni zoyera, ma valve, mipando, akasupe ndi ndime za mpweya kuchokera ku carbon deposits, chotsani ndi kutulutsa payipi yoyamwa. Pa nthawi yomweyo fufuzani chikhalidwe cha unloader ndi zothina mavavu. Mavavu ovala a lappe omwe samasindikiza pamipando, ndipo ngati izi sizikuyenda bwino, m'malo mwake ndi zina zatsopano. Mavavu atsopano ayeneranso kuwangidwa.

Poyang'ana chotsitsacho, samalani ndi kayendedwe ka plungers mu tchire, zomwe ziyenera kubwerera kumalo awo oyambirira popanda kumangirira pansi pa machitidwe a akasupe. Zimafunikanso kuyang'ana kulimba kwa kugwirizana pakati pa plunger ndi bushing. Chifukwa chosakwanira kumangiriza kungakhale mphete ya mphira ya mphira, yomwe pakadali pano iyenera kusinthidwa ndi yatsopano.

Mukayang'ana ndikusintha mphete, musachotse mutu wa compressor, koma chotsani chitoliro cha mpweya, chotsani mkono wa rocker ndi kasupe. Plunger imatulutsidwa muzitsulo ndi mbedza ya waya, yomwe imalowetsedwa mu dzenje lokhala ndi mainchesi 2,5 mm lomwe lili kumapeto kwa plunger, kapena mpweya umaperekedwa ku njira yopingasa ya chipangizo cha jekeseni.

Mafuta ma plungers ndi CIATIM-201 GOST 6267-59 mafuta musanayike m'malo mwake.

Kukhetsa kwathunthu kwamadzi kuchokera kumutu ndi cylinder block ya kompresa kumachitika kudzera pa valve valve yomwe ili pabondo la chitoliro cha compressor. Ngati kugogoda kumachitika mu kompresa chifukwa cha kuchuluka kwa kusiyana pakati pa zolumikizira ndodo ndi magazini crankshaft, m'malo kompresa kulumikiza ndodo fani.

Werengani komanso Kuyendetsa galimoto ZIL-131

Ngati kompresa sapereka kukakamizidwa kofunikira mu dongosolo, choyamba yang'anani mkhalidwe wa mapaipi ndi maulumikizidwe awo, komanso kulimba kwa ma valve ndi chowongolera chowongolera. Kulimba kumafufuzidwa ndi khutu kapena, ngati mpweya wotuluka ndi wochepa, ndi yankho la sopo. Zomwe zimayambitsa kutayikira kwa mpweya zitha kukhala kutayikira kwa diaphragm, komwe kumawonekera kudzera pamalumikizidwe opangidwa ndi ulusi kumtunda kwa thupi kapena pabowo lakumunsi kwa thupi ngati valavu siili yolimba. Bwezerani mbali zotuluka.

MAZ compressor chipangizo

Compressor (mkuyu 102) ndi pisitoni ya silinda iwiri yoyendetsedwa ndi V-belt kuchokera ku pulley ya fan. Mutu wa silinda ndi crankcase zimangiriridwa ku cylinder block, ndipo crankcase imatsekeredwa ku injini. Pakatikati mwa chipika cha silinda pali chibowo pomwe chotsitsa kompresa chili.

Mpunga. 102.MAZ Compressor:

1 - pulagi yoyendetsa ya crankcase ya compressor; 2 - compressor crankcase; 3 ndi 11 - mayendedwe; 4 - chivundikiro kutsogolo kwa kompresa; 5 - bokosi lodzaza; 6 - mchere; 7 - compressor yamphamvu chipika; 8 - pisitoni ndi ndodo yolumikizira; 9 - mutu wa chipika cha masilindala a kompresa; 10 - kusunga mphete; 12 - kutulutsa mtedza; 13 - kumbuyo chivundikiro cha kompresa crankcase; 14 - chosindikizira; 15 - chisindikizo cha masika; 16 - crankshaft; 17 - masika a valve; 18 - valve yolowera; 19 - chowongolera cha valve; 20 - kasupe wowongolera mkono wa rocker; 21 - kasupe wa rocker; 22 - tsinde la valve yolowera; 23 - wogwedeza; 24 - plunger; 25 - mphete yosindikiza

Makina opangira kompresa amasakanikirana. Mafuta amaperekedwa pansi pa kukakamizidwa kuchokera ku mzere wa mafuta a injini kupita ku ndodo zolumikizira. Mafuta otuluka kuchokera ku ndodo zolumikizira amapopera, amasandulika kukhala nkhungu yamafuta ndikuthira pagalasi la silinda.

Chozizirira chopondereza chimadutsa mupaipi kuchokera pa choziziritsira injini kupita ku cylinder block, kuchokera pamenepo kupita kumutu wa silinda ndipo chimatulutsidwa m'bowo la mpope wamadzi.

Mpweya womwe umalowa mu kompresa umalowa pansi pa mavavu a bango 18 omwe ali mu cylinder block. Ma valve olowera amayikidwa mu maupangiri 19, omwe amachepetsa kusamuka kwawo. Kuchokera pamwamba, ma valve amapanikizidwa pampando ndi kasupe wa valve yolowera. Kusunthira mmwamba kwa valavu kumachepetsedwa ndi ndodo yowongolera masika.

Pamene pisitoni ikupita pansi, vacuum imapangidwa mu silinda pamwamba pake. Njirayi imalumikizana ndi malo omwe ali pamwamba pa pisitoni ndi patsekeke pamwamba pa valavu yolowera. Chifukwa chake, mpweya womwe umalowa mu kompresa umagonjetsa mphamvu yamasika ya vavu yolowera 17, ndikuikweza ndikuthamangira mu silinda kuseri kwa pistoni. Pamene pisitoni zimayenda mmwamba, mpweya ndi wothinikizidwa, kugonjetsa mphamvu ya Bwezerani valavu kasupe, kugwetsa pa mpando ndi kulowa mphanga kupangidwa kuchokera mutu kudzera nozzles mu dongosolo pneumatic wa galimoto.

Kutsitsa kompresa podutsa mpweya kudzera mu mavavu otsegula olowera kumachitika motere.

Pamene kuthamanga kwakukulu kwa 7-7,5 kg / cm2 kumafikira mu dongosolo la pneumatic, chowongolera chowongolera chimatsegulidwa, chomwe nthawi yomweyo chimadutsa mpweya woponderezedwa munjira yopingasa yotsitsa.

Pansi pa kupanikizika kowonjezereka, ma pistoni 24 pamodzi ndi ndodo 22 amawuka, kugonjetsa kukanikiza kwa akasupe a mavavu olowera, ndi manja a rocker 23 nthawi imodzi amang'amba ma valve onse awiri pampando. Mpweya umayenda kuchokera ku silinda imodzi kupita ku inzake kupita ku mipata yomwe imapangidwa kudzera munjira, momwe imayimitsira mpweya woponderezedwa kupita ku makina a pneumatic.

Pambuyo kuchepetsa kuthamanga kwa mpweya mu dongosolo, kuthamanga kwake mu njira yopingasa yolumikizidwa ndi chowongolera kuthamanga kumachepa, ma plungers ndi ndodo zotsitsa zimatsika pansi pakuchita kwa akasupe, ma valve olowera amakhazikika pamipando yawo, ndi njira yokakamiza mpweya kulowa. dongosolo pneumatic likubwerezedwa kachiwiri.

Nthawi zambiri, kompresa imathamanga osatsitsa, ikukoka mpweya kuchokera pa silinda imodzi kupita ina. Mpweya umalowetsedwa mu dongosolo la pneumatic pokhapokha ngati kuthamanga kutsika pansi pa 6,5-6,8 kg / cm2. Izi zimatsimikizira kuti kupanikizika mu dongosolo la pneumatic kuli kochepa ndipo kumachepetsa kuvala pazigawo za compressor.
