磁力探伤简便直观,但是,通常的磁悬液用油量(一般是按1:1的变压器油和煤油混合)较大。例如:一根直径85×1040mm东方红-75曲轴表面一次能粘附200～300克混合油,特别是当轴颈油孔和蒙头螺栓孔进了油的时候油耗量更大;又如连杆表面大部分是毛面,对油有很好的粘附力,每一百根6135连杆能粘走5～6kg 混合油。工件探完伤后油液随工件流到产品架或地上,则影响文明生产,操作者也往往弄得满身是油污。变压器油的粘度和比重比煤油大,往往沉浸在
Magnetic inspection is simple and intuitive, however, the amount of oil typically used for magnetic suspensions (typically 1: 1 transformer oil and kerosene). For example: a diameter of 85 × 1040mm Dongfanghong-75 crankshaft surface can be adherent 200 to 300 grams of mixed oil, especially when the journal hole and the head bolt hole into the oil when the fuel consumption greater; Most of the rod surface is matte, the oil has a good adhesion, every one of the 6135 connecting rod can stick away 5 ~ 6kg mixed oil. After the wounding of the workpiece, the oil flows to the product rack or the ground with the workpiece, which affects the production of civilized products. The operators also often make it covered with oil. Transformer oil viscosity and specific gravity than kerosene, often immersed in
