Gwajin Tauri na Toshe-toshe na Silinda na Inji da Kan Silinda

A matsayin manyan sassan, tubalan silinda na injin da kawunan silinda dole ne su jure yanayin zafi da matsin lamba mai yawa, tabbatar da ingantaccen rufewa, kuma su bayar da kyakkyawan jituwa da haɗuwa. Alamomin fasaha, gami da gwajin tauri da gwajin daidaiton girma, duk suna buƙatar kulawa mai tsauri ta amfani da kayan aiki na daidai. Ana amfani da gwajin tauri na tubalan silinda da kawunan galibi don tantance halayen injiniya na kayan, don tabbatar da cewa sun cika buƙatun ƙira.

Masu gwajin taurin Rockwell sun dace da tantance taurin manyan saman da ke lebur kamar jiragen silinda (misali, saman haɗin kan silinda, ƙasan silinda) da fuskokin ƙarshen ramin crankshaft. Don duba ingancin kan layi a cikin layukan samarwa, ana iya samar da buƙatun gwaji na musamman. Ana iya haɗa masu gwajin taurin Rockwell ta atomatik tare da layin samarwa don cimma aikin da ba na matuki ba, tare da ingantaccen aiki da sakamako mai karko. Wannan hanyar gwaji ita ce aka fi amfani da ita wajen samar da kayan aikin mota da yawa kuma ta bi ƙa'idodin ISO 6508 da ASTM E18.

Ana amfani da na'urorin gwajin taurin Brinell don gwajin taurin kai na guraben tubalan silinda da sassan da ke da kauri (misali, bangon gefen tubalan silinda), kuma sun dace musamman don kimanta ingancin jefawa da ingancin maganin zafi na tubalan silinda na ƙarfe mai siminti. Ya kamata a lura cewa gwajin Brinell yana barin manyan ramuka, don haka ya kamata a guji shi a kan sassan da suka lalace cikin sauƙi kamar saman ciki na bangon silinda da saman da aka yi da injin daidai.

Gwaje-gwajen taurin Vickers sun dace da gwajin taurin sassan siraran bango na tubalan silinda na aluminum, saman ciki na layin silinda (don guje wa lalata saman rufewa), da kuma gwajin saurin taurin yadudduka da shafi da aka yi wa zafi (misali, yadudduka masu nitride, yadudduka masu katsewa) akan saman toshe silinda. Wannan hanyar gwaji ta dace da buƙatun gwajin daidaito na injunan sararin samaniya da manyan motoci, kuma ta bi ƙa'idodin ISO 6507 da ASTM E92.

Dangane da tubalan silinda da kawunan silinda da aka yi da kayayyaki daban-daban, ana iya amfani da ma'aunin tauri masu zuwa:

Dangane da buƙatun gwaji daban-daban na tubalan silinda na injin, Laizhou Laihua na iya samar da mafita na musamman bisa ga takamaiman samfura. Wannan ya haɗa da samfuran yau da kullun, samfuran da aka keɓance na cikakken nau'in gwajin tauri na Rockwell, Brinell, da Vickers, da kuma ƙirar kayan aiki na musamman waɗanda aka tsara don samfuran - duk an yi nufin haɓaka aikin gwaji da daidaiton ma'auni.
