(1) Tarisa neruvara inopinda mukati: nyudza musoro wecylinder muparafini kana parafini coloring solution (chikamu chikuru che 65% parafini, 30% transformer mafuta, 5% turpentine uye shoma shoma yemafuta emutobvu), bvisa mushure me2h. , uye pukuta pakaoma Oiri mavara pamusoro, akaputirwa neakatetepa chena poda paste, wozoomeswa, kana paine makatsemuka, dema (kana mavara) mitsetse ichaonekwa.

(2) Muedzo wemvura yekumanikidza: isa musoro wecylinder uye gasket pane cylinder block, isa ndiro yekuvharisa pamadziro evhavhavhavhavhavhavha, uye batanidza pombi yemvura kune hydraulic press kuti iname dzimwe nzira dzemvura, wobva wadzvanya mvura muhumburumbira Muviri uye humburumbira musoro. Chinodiwa ndechekuti: pasi pekumanikidzwa kwemvura kwe200～400 kPa, chengetedza kwete pasi pe5s, uye hapafanirwe kuve nekudonha. Kana mvura ichibuda kunze, panofanira kuva nekutsemuka.

(3) Oil pressure test: Baira peturu kana parafini mujaketi remvura recylinder block uye cylinder head, uye tarisa kuvuza mushure mehafu yeawa.

(4) Kuedzwa kwemhepo yemhepo: Kana muedzo wemhepo uchishandiswa pakuongorora, musoro we cylinder unofanira kunyudzwa mumvura yevanhu, uye nzvimbo yezvimedu inofanira kuongororwa kubva kune mabhubhu anobuda pamusoro pemvura. Iwe unogona kushandisa mhepo yakamanikidzwa ye138 ~ 207 kPa kuti upfuure nemugero kuti uongororwe, chengetedza kudzvanywa kwe30 s, uye tarisa kana paine kubuda kwemhepo panguva ino.
