(1) Pistoni ndi pisitoni mphete zotayikira zolakwika

Kukwanira pakati pa pistoni ndi chilolezo cha khoma la silinda kumakhudzana mwachindunji ndi momwe injiniyo imapangidwira komanso moyo wautumiki. Pokonza injini ndi kuyang'anitsitsa, ikani pisitoni mozondoka m'chobowo cha silinda, ndipo ikani choyezera cha makulidwe oyenera ndi kutalika mu silinda nthawi yomweyo. Pamene kupanikizika kwa mbali kumagwiritsidwa ntchito, khoma la silinda ndi pisitoni zimagwirizana ndi kuponyedwa pamwamba pa pistoni. Gwiritsani ntchito kasupe kuti musindikize mphamvu yokoka yotchulidwa kuti Ndikoyenera kutulutsa geji ya makulidwe pang'onopang'ono, kapena kuyeza kukula kwa siketi ya pistoni ndi micrometer yakunja, ndiyeno kuyeza kukula kwa silinda ndi silinda yoboola geji. Silinda ya silinda yomwe inali ndi kuchotsera kunja kwake kwa siketi ya pistoni ndiyokwanira.

(2) Kuzindikira ndi kuthetsa mavuto a pistoni ndi mphete za pisitoni

Ikani mphete ya pisitoni mophwanyika mu silinda, kanikizani mpheteyo kuti ikhale yophwanyika ndi pisitoni yakale (posintha mphete kuti ikonzenso pang'ono, ikani pamalo pomwe mphete yotsatira imasunthira potsika), ndipo yesani kusiyana kotsegula ndi makulidwe. gauge. Ngati mpata wotsegulira ndi wochepa kwambiri, gwiritsani ntchito fayilo yabwino kuti mupange pang'ono pamapeto otsegulira. Kuyang'ana pafupipafupi kuyenera kuchitidwa panthawi yokonza mafayilo kuti asatsegulidwe kukhala wamkulu, ndipo kutsegulira kuyenera kukhala kosalala. Pamene mphete yotsegula yatsekedwa kuti iyesedwe, pasakhale kupotoza; mapeto osungidwa ayenera kukhala opanda burrs. Yang'anani m'mbuyo, ikani mphete ya pistoni mumphepete mwa mphete ndikuzungulira, ndikuyesa kusiyana kwake ndi geji yochuluka popanda kupereka pini. Ngati chilolezocho ndi chaching'ono kwambiri, ikani mphete ya pistoni pa mbale yathyathyathya yokutidwa ndi nsalu ya emery kapena mbale yagalasi yokhala ndi valavu ya mchenga ndikupera woonda. Yang'anani kumbuyo ndikuyika mphete ya pistoni mumphepete mwa mphete, mpheteyo ndi yotsika kuposa groove bank, apo ayi ring groove iyenera kusinthidwa kuti ikhale yoyenera.
