检测在风机外壳内观测的撞痕的方法
Abstract:
本发明涉及一种用于检测在风机外壳（100）的内表面（104）上出现的撞痕（Ii）的方法，所述方法的特征在于，它包括以下步骤：发现在所述风机外壳（100）的所述内表面（104）上出现的第一撞痕（I1）的步骤（201）；界定包括所述第一撞痕（I1）的检测区域（106）的步骤（202）；发现在所界定的所述检测区域（106）上出现的不同撞痕（Ii）的步骤（203），所述不同的被发现的撞痕形成一组被考虑的撞痕；对于被考虑的每个撞痕（Ii），测量所述撞痕（Ii）的深度和长度的步骤（204）；对于被考虑的每个撞痕（Ii），通过将被考虑的每个撞痕的所述深度和长度与危害性水平相关联的至少一个图表（300；400）确定危害值的水平的步骤（205）；对于包括第一撞痕（I1）的所述检测区域（106），通过对被考虑的每个撞痕（Ii）所确定的危害水平作加法确定危害值的总体水平的步骤（206）。
Abstract(English):

The present invention relates to a method for inspecting impacts (Ii) present on an internal face (104) of a fan casing (100). The method is characterized in that the method comprises the following steps: spotting (201) a first impact (I1) present on the internal face (104) of the fan casing (100); delimiting (202) an inspection area (106) containing the first impact (I1); spotting (203) the various impacts (Ii) present in the delimited inspection area (106), the various spotted impacts forming a set of impacts to be considered; measuring (204), for each impact (Ii) that is to be considered, the depth of length of the impact (Ii); for each impact (Ii) to be considered, determining (205) a harmfulness value, using at least one chart (300; 400) relating the depth and length of each impact to be considered to a level of harmfulness; determining (206), for the inspection area (106) containing the first impact (I1), a total harmfulness value by adding together the harmfulness level determined for each impact (Ii) to be considered.
