Answer
Ana amfani da Shimming don daidaita tsayin da aka shigar $H_1$ na magudanar ruwa don tabbatar da cewa an riga an shigar da $P_1$ ya faɗi cikin ɗan ƙaramin haƙuri. Saboda $P = k \cdot (H_0 - H_1)$, ko da ƙananan bambance-bambance a cikin zurfin mahalli ko faɗin ɗaki na iya haifar da manyan kurakurai $P_1$. Lokacin amfani da shims, yana da mahimmanci don tabbatar da cewa shim ɗin yana da lebur kuma ya rufe gabaɗayan fuskar tuntuɓar magudanar ruwa. Idan shim ɗin ya yi ƙanƙara sosai, raƙuman ruwan bazara na iya yin sama da ƙasa, yana haifar da lanƙwasawa na gida da kuma lodi mara sifofi. A cikin manyan igiyoyin igiya masu sauri, injiniyoyi sukan yi amfani da jeri na 0.05 mm shims don daidaita abubuwan da aka riga aka yi, suna auna karfin juzu'in farawa a matsayin wakili na axial force. Kayan shim yakamata ya dace da kayan bazara don hana lalata galvanic.
