Piston mphete.
Mphete ya piston imagwiritsidwa ntchito kuyika poyambira piston mkati mwa mphete yachitsulo, mphete ya piston imagawidwa m'mitundu iwiri: kuphatikizika mphete ndi mphete ya mafuta ndi mphete yamafuta. Nnenete yosokoneza imatha kugwiritsidwa ntchito kusindikiza osakaniza mu chipinda cha kuyaka; Mphete yamafuta imagwiritsidwa ntchito popukutira mafuta owonjezera kuchokera pa silinda. Mphete ya piston ndi mtundu wa mphete yachitsulo yotupa yokhala ndi kuphatikizika kwakukulu kwakunja, komwe kumasonkhana mu mbiriyo ndi poyambira poofare. Kubwezeretsanso mphete za piston kudalira pang'onopang'ono kusiyana kwa mpweya kapena madzi kuti mupange chidindo pakati pa mphete yakunja ndi sing'anga ndi mbali imodzi ya mphete ndi poyambira mphete.
Kuchuluka kwa ntchito
Mphete za piston zimagwiritsidwa ntchito kwambiri m'makina osiyanasiyana amphamvu, monga injini zamafuta, injini zama dizili, zopindika, zopindika, zombo, zombo zowonjezera. Nthawi zambiri, mphete ya piston imayikidwa poyambira pisitoni, ndipo iyo ndi piston, cylinder amer, mutu wa silinda ndi zigawo zina za chipindacho chizigwira ntchito.
Piston mphete ya piston ndi gawo la mafuta mkati mwa injini yamafuta, iyo ndi silinda, piston, khonde la silinda limodzi kuti mumalize chidindo cha mafuta. Ma injini wamba omwe amagwiritsidwa ntchito amakhala ndi mitundu iwiri ya dizilo, chifukwa cha mafuta awo osiyanasiyana, chifukwa cha mphete za piston, zomwe zimapangidwa ndi matebulo okhazikika, ecroplating, chrome Kulemba, etc.
Ntchito ya mphete ya piston imaphatikizapo kusindikiza, mafuta oyendetsera mafuta (kuwongolera mafuta), kuphatikiza kutentha (kusamutsa kutentha), chitsogozo (chitsogozo) maudindo anayi. Kusindikizidwa: Kunena za kusindikiza mpweya, musalole kuyamwa kwa chipinda cha mpweya ku crankcase, kutulutsa kwa gasi kumayendetsedwa pang'ono, kusintha mphamvu ya mafuta. Kutulutsa kwa mpweya sikungangochepetsa mphamvu ya injini, komanso kumapangitsa kuwonongeka kwa mafuta, komwe ndi ntchito yayikulu ya mphete yamagesi; Sinthani mafuta (mafuta opangira mafuta) Mafuta owonjezera pa khoma la siliva amakambasulidwa ndi filimu yopyapyala kuti muwonetsetse kuti mafuta a silinda ndi pisitoni, yomwe ndi ntchito yayikulu ya mphete ya mafuta. M'matsenga amakono othamanga, chidwi chapadera chimalipira gawo la fiston mphete yowongolera mafuta; Kutentha kwa kutentha: Kutentha kwa pistoni kumafalikira kwa cylinder kuyamwa mphete ya piston, ndiye kuti, zotsatira zabwino. Malinga ndi deta yodalirika, 70 ~ 80% ya kutentha komwe adalandiridwa ndi piston pisiton yolumikizidwa ndi pisitoni yozizira imabalalitsidwa ndi mphete ya cugen; Chithandizo: Mphete ya piston imasunga pisitoni mu silindayo, imalepheretsa kulumikizana mwachindunji ndi khoma la cylinder, amalitse chipika cha pisitoni, ndipo chimalepheretsa pisitoni kugwetsa silinda. Nthawi zambiri, piston ya injini ya mafuta imagwiritsa ntchito mphete ziwiri ndi mphete imodzi yamafuta, pomwe injiniyo imagwiritsa ntchito mphete ziwiri ndi mphete imodzi yamafuta.
Chizindikiritso chabwino komanso choyipa
Kugwira ntchito kwa mphete ya piston sikudzakhala ndi nipike, kuyika, kupindika kunja kwa mphete kulibe 0.15-0.25 mm mphete ya piston ikwaniritse zofunika. Kuphatikiza apo, tiyeneranso kuwunika mphete ya piston, ndiye mphete ya piston ndi mphete yocheperako, ndikuyika khoma lowunikira lomwe lili pamwambapa, kenako ndikuwona khoma la cuton ndi labwino. Pakakhala zovuta zina, kusungitsa mizere ya piston yoyesedwa ndi gaude ya makulidwe sikuyenera kupitirira 0.03 mm. Kutalika kwa kusanja kosasunthika sikuyenera kukhala wamkulu kuposa 1/3 wa cylinder dinemeter, kutalika kwa ma cylinder diameter diamer, motero, ziyenera kusinthidwa. Piston Mphembe ya GO / T 1149.1-94 imafotokoza kuti mphete zonse za piston zimafunikira kuti chitsogozo chizikhala cholowera kumtunda, ndiye kuti, mbali pafupi ndi chipinda cha kuyaka. Mphete zodziwika bwino pamzere wapamwamba zimaphatikizapo: Chingwe cha Connge, chamiyendo chamkati, chodula chakunja, mphete yam'mimba yofunikira kuyikapo.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga nkhani zina patsamba lino!
Chonde ndiyitane ngati mukufuna zinthu ngati izi.
