我厂使用的兰炼产 QXJ 型气动指示记录调节仪记录笔系统,是由记录笔尖、笔杆、指针架等组成。在仪表的使用过程中常常出现墨水不畅,笔尖堵塞,造成记录中断,影响仪表的正常运行。分析其原因,主要是记录笔尖导管过细使墨水不易流出(内径仅0.2毫米)。针对以上问题,我们对仪表的记录笔进行了研究,发现笔杆导管内径为0.5毫米,比笔尖导管大2.5倍,经实验证明可用它代替笔尖导管,使笔杆笔尖一体化。现把改进 I plant using blue refining QXJ-type pneumatic indicator recorder regulator pen system is recorded by the pen tip, pen, pointer frame and other components. In the process of using the instrument often appear poor ink, pen tip is blocked, resulting in recording interruption, affecting the normal operation of the instrument. Analysis of the reasons, mainly to record the pen tip catheter so that the ink is not easy outflow (diameter of only 0.2 mm). In view of the above problems, we have carried out a research on the stylus pen and found that the penile catheter has an inner diameter of 0.5 mm, which is 2.5 times larger than the pen tip catheter. It has been experimentally proved that it can be used instead of the pen tip catheter to integrate the pen tip. Now to improve
