我国进口了不少英国泰勒——霍布森公司的圆度仪。为了使这些仪器正常工作,我们介绍有关故障修理的几个例子,仅供参考。一、51型计算机部分故障排除 1.记录笔的位置和对中表刻度不同步, 记录笔线圈和对中表是串联的,正常时它们的指示位置是相互对应的。对中表的满刻度电流为30mA。记录笔在记录纸中心时和对中表在中间刻线时的电流为14或者15mA,从纪录纸中间位置到纸的最外圈(或最里圈)的线圈电流应为4mA,如果纪录笔线圈电流是线性的,那么纪录笔从中间位置到最外圈或最里圈的线圈电流应该是各为4mA,对中表应与它相对应,否则就不会同步。调正时应以纪录笔的位置来调整对中心表调零螺丝,使对中心表指
China imported a lot of British Taylor - Hobson’s roundness meter. In order for these instruments to work properly, we present a few examples of troubleshooting, for reference purposes only. First, the 51 computer part of the troubleshooting 1 record pen position and alignment of the table is not synchronized, recording pen coil and the table is in series, their normal position when they correspond to each other. The full scale current to the meter is 30mA. When the stylus is at the center of the recording paper and when the centering chart is in the middle, the current is 14 or 15mA. The current from the middle of the recording paper to the outermost (or innermost) coil of the paper should be 4mA. If the stylus The coil current is linear, so the current from the middle of the stylus to the outermost or innermost coil should be 4mA each, and the center table should correspond to it, otherwise it will not be synchronized. Adjust the time should be recorded pen position to adjust the center table zero screw, so that the center of the table
