Udindo waukulu wa mphete ya pistoni yamagalimoto
Mu "mtima wamphamvu" weniweni wa injini yamagalimoto, mphete ya pistoni mosakayikira ndiyo chitetezo chofunikira, imagwira ntchito zingapo zofunika zomwe zimakhudza mwachindunji magwiridwe antchito ndi moyo wa injini.
Choyamba, ili ndi ntchito yotseka, yomwe imamatirira mwamphamvu ku pistoni ndi khoma la silinda, ngati chotchinga cholimba, kuletsa mpweya wotentha kwambiri komanso wopanikizika kwambiri m'chipinda choyaka kuti usatuluke mu crankcase, kuonetsetsa kuti kuthamanga kwa silinda kuli kolimba komanso kupereka mphamvu yokwanira yotulutsa mphamvu ya injini. Kutsekako kukalephera, mphamvu yoyaka ya injini idzachepa kwambiri, ndipo mphamvuyo idzachepanso.
Kachiwiri, ili ndi ntchito yowongolera mafuta. Pamene pisitoni ikuyenda mmwamba ndi pansi mu silinda, imakhala ngati chotsukira mosamala, ikuchotsa mafuta ochulukirapo pakhoma la silinda kuti mafuta asalowe m'chipinda choyaka kuti ayake, motero imawongolera bwino kugwiritsa ntchito mafuta ndikuchepetsa ndalama zogwirira ntchito. Nthawi yomweyo, imatha kupanga filimu yamafuta yofanana pakhoma la silinda, kupereka mafuta abwino a pisitoni ndi khoma la silinda, kuchepetsa kuwonongeka.
Kuphatikiza apo, mphete ya pistoni ilinso ndi ntchito zoyendetsera kutentha ndi kuthandizira. Mu malo ogwirira ntchito otentha kwambiri komanso opanikizika kwambiri a injini, imatha kusamutsa mwachangu kutentha kwakukulu komwe kumapangidwa ndi pamwamba pa pistoni kupita kukhoma la silinda, kenako nkuitulutsa kudzera mu makina oziziritsira, kuonetsetsa kuti injini ikugwira ntchito pa kutentha koyenera. Nthawi yomweyo, imatha kuthandiza kuyenda kwa pistoni ndikupereka chithandizo chokhazikika, kuletsa pistoni kukhudza mwachindunji khoma la silinda ndikupangitsa kuti iwonongeke.
Zolakwika ndi zizindikiro za mphete za pistoni zamagalimoto
Ngakhale kuti mphete ya pistoni imagwira ntchito yofunika kwambiri, n'zosatheka kukumana ndi zolakwika mukamagwira ntchito m'malo ovuta, makamaka omwe amaonekera ngati kusweka, kusweka, ndi kumamatira, kutsatiridwa ndi zizindikiro zingapo zoonekeratu.
Mphete ya pistoni ikasweka, mphamvu yotsekera imachepa, ndipo mpweya womwe uli mu chipinda choyaka umatuluka, zomwe zimapangitsa kuti mphamvu ya injini isakwane, kuchedwa kwa liwiro, komanso kuvutika kuthamanga kapena kukwera. Nthawi yomweyo, mafuta amatha kulowa mu chipinda choyaka kuti akayaka, zomwe zimapangitsa kuti mafuta agwiritsidwe ntchito mopitirira muyeso, zomwe zimafuna kuwonjezera mafuta nthawi zambiri, ndipo utsi wabuluu umatuluka kuchokera mu chitoliro chotulutsa utsi, makamaka pamene kuzizira kumayamba kapena kuthamanga kwambiri. Kuphatikiza apo, kuyaka kosakwanira kudzapangitsa kuti mafuta a injini agwiritsidwe ntchito mopitirira muyeso, kupitirira miyezo yotulutsa utsi, komanso kugwedezeka kosagwira ntchito komanso kutentha kwambiri kwa injini.
Kusweka kwa mphete ya pistoni ndi vuto lalikulu kwambiri, lomwe nthawi zambiri limayamba chifukwa cha mavuto a kapangidwe kake, kuwonongeka kwakukulu kwa silinda, kutsekeka kwa kaboni, kukula kosayenera kwa mphete, kapena katundu wochuluka wogwiritsidwa ntchito. Pambuyo pa kusweka, padzakhala phokoso lomveka bwino lachitsulo mkati mwa injini ikayamba kuthamanga kapena kuzizira, ndipo phokoso lidzamveka bwino. Nthawi yomweyo, mphamvu ya injini idzatsika kwambiri, ndipo kuthamanga kwa mafuta kungakhalenso kosazolowereka.
Kumamatira kwa mphete ya pistoni kumachitika makamaka chifukwa cha mafuta odetsedwa, kukhuthala kwakukulu, kumamatira kwa mphete ya pistoni mu groove ya mphete, kapena kuchuluka kwa mpweya woipa womwe umayambitsa kutsekeka kwa groove ya mphete. Kumamatira kudzapangitsa mphete ya pistoni kutaya kulimba ndikulephera kumamatira mwamphamvu ku khoma la silinda, zomwe zimapangitsa kuti pakhale zizindikiro zomwezo za kulephera kutseka, kuchuluka kwa kugwiritsa ntchito mafuta, komanso kuchepa kwa mphamvu.
Kuzindikira ndi njira zothetsera mavuto a mphete ya piston yamagalimoto
Galimoto ikawonetsa zizindikiro zomwe zili pamwambapa, ndikofunikira kuzindikira mphete ya piston nthawi yake. Njira zodziwika bwino zodziwira matenda zimaphatikizapo kuyang'anira endoscope, kuwona kuchuluka kwa mpweya pamwamba pa piston ndi matope a mafuta mu mphuno ya mphete kudzera mu dzenje la spark plug; kuyesa kuthamanga kwa silinda, ngati kuthamanga kwa silinda kuli bwino koma mafuta akugwiritsidwa ntchito kwambiri, nthawi zambiri kumakhala vuto la mphete ya piston; njira yowonera yosinthika, kutseka dzenje la dipstick la mafuta munthawi yozizira, kuzindikira momwe mpweya umatulukira ndikugwiritsa ntchito minofu kuti izindikire kayendedwe ka mpweya; kuyang'ana njira yochotsera, kuyang'ana patsogolo kuwunika kwa zinthu zomwe zimawonongeka mosavuta monga ma valve otulutsa utsi ndi ma turbocharger, kenako kutsimikizira vuto la mphete ya piston; kuyesa wothandizira kukonza, kuwonjezera wothandizira wotulutsa mphete ya piston ndikuyang'anira kusintha kwa kugwiritsa ntchito mafuta kuti adziwe kuchuluka kwa kumamatira.
Pa zolakwika zosiyanasiyana, mayankho amasiyananso. Pa kuwonongeka pang'ono kapena kumamatira, chokonzera chapadera cha mphete ya piston chingagwiritsidwe ntchito kubwezeretsa kulimba ndi magwiridwe antchito a mphete ya piston popanda kusokoneza injini. Mwachitsanzo, ukadaulo wokonza "Siyou Pu 2 + 18 wosawononga" ukhoza kugwira ntchito pa mkhalidwe womangika wa mphete ya gasi ndi mphete yamafuta nthawi imodzi, kuchita kukonza kwamphamvu pansi pa mikhalidwe yoyendetsera kuti apewe chiopsezo cha kuwonongeka kwachiwiri. Ngati mphete za piston zawonongeka kwambiri kapena kusweka, ziyenera kusinthidwa nthawi yomweyo. Mukasintha, ndikofunikira kusankha zinthu zodalirika ndikupita ku sitolo yaukadaulo ya 4S kapena shopu yokonzera, komwe akatswiri azichita ntchitoyi. Chifukwa kusintha mphete za piston kumafuna kusokoneza injini, njirayi ndi yovuta. Ngati kukhazikitsa sikunachitike bwino, kungakhudze magwiridwe antchito a injini komanso kuwononga kwambiri. Kuphatikiza apo, pakuyendetsa tsiku ndi tsiku, kusintha mafuta a injini ndi fyuluta yamafuta nthawi zonse, kugwiritsa ntchito mafuta apamwamba, ndikupewa injini kuti isagwire ntchito mopitirira muyeso kwa nthawi yayitali kungathandize kukulitsa moyo wa mphete za piston ndikuchepetsa kuwonongeka.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
