(1) Izici zephutha zokuvuza iringi ye-piston ne-piston

Ukulingana phakathi kwepiston kanye ne-cylinder wall clearance kuhlobene ngokuqondile nekhwalithi yokugcinwa kwenjini kanye nempilo yesevisi. Ngesikhathi sokulungiswa kwenjini nokuhlola, beka ipiston ibheke phansi kusilinda, bese ufaka igeji yokujiya nobude obufanele kusilinda ngesikhathi esifanayo. Lapho kufakwa ingcindezi eseceleni, udonga lwesilinda kanye nepiston kuhambisana nendawo yokuphonswa kwepiston. Sebenzisa ibhalansi yasentwasahlobo ukuze ucindezele amandla okudonsa ashiwo kuya Kufanelekile ukukhipha igeji yokujiya ngobumnene, noma uqale ulinganise ububanzi besiketi se-piston nge-micrometer yangaphandle, bese ukala ububanzi besilinda nge-cylinder bore gauge. I-cylinder bore khipha ububanzi obungaphandle besiketi se-piston yi-fit clearance.

(2) Ukuxilongwa nokuxazululwa kwezinkinga zokuvuza kwepiston neringi

Beka indandatho yepiston isicaba kusilinda, phusha iringi ibe flat ngepiston endala (uma ushintsha iringi ukuze ilungiswe kancane, yiphushele endaweni lapho iringi elandelayo ihamba khona iye endaweni ephansi), bese ukala igebe lokuvula ngogqinsi. igeji. Uma igebe lokuvula lincane kakhulu, sebenzisa ifayela elihle ukuze ufake kancane ekugcineni kokuvula. Ukuhlolwa okuvamile kufanele kwenziwe ngesikhathi sokulungiswa kwefayela ukuze kuvinjwe ukuvuleka kungabi kukhulu, futhi ukuvulwa kufanele kube flat. Uma ukuvuleka kweringi kuvaliwe ukuze kuhlolwe, akumele kube khona ukuchezuka; isiphetho esifakiwe kufanele singabi nama-burrs. Hlola i-backlash, faka indandatho ye-piston ku-groove eyindandatho bese uzungezisa, futhi ulinganise igebe ngegeji yokuqina ngaphandle kokukhipha iphinikhodi. Uma imvume incane kakhulu, faka indandatho yepiston epuleti eliyisicaba elimbozwe ngendwangu ye-emery noma ipuleti lengilazi elimbozwe nge-sand valve bese ugaya ube mncane. Hlola i-backlash bese ufaka indandatho ye-piston emgodini wendandatho, indandatho iphansi kune-groove bank, ngaphandle kwalokho i-groove ring kufanele iguqulwe ibe yindawo efanele.
