本所研制的ZL-1型铸铝转子检查仪,最近通过了模样鉴定。它采用“开口变压器”感应原理,把检测信号经过放大,直接由表头指示信号的大小。根据信号的大小判定缺陷的严重程度。仪器的定位系统能自动指示缺陷所在的位置。该检查仪主要用来检查铸铝转子是否存在“断条”、“细条”、“错片”、“盲孔”以及严重缩孔等缺陷,它具有检查可靠、迅速、方便等特点。现简述如 The developed ZL-1 cast aluminum rotor tester, recently passed the identification of the model. It uses the “open transformer” sensing principle, the detection signal after amplification, directly from the header indicates the size of the signal. According to the size of the signal to determine the severity of defects. The instrument’s positioning system automatically indicates the location of the defect. The tester is mainly used to check cast aluminum rotor for the presence of “broken bar”, “thin strip”, “wrong piece”, “blind hole” and serious shrinkage and other defects, it has the inspection of reliable, rapid and convenient features. Now briefly as
