QXJ—313B气动单笔双针记录调节仪,由于性能可靠,观察记录方便,无需对针即可实现“手动一自动”无扰动切换等特点,因此,广泛用于石油、化工企业及科研单位的自控系统中。根据实际经验和有关资料,总结调校方法和步骤如下。一、外观检查 1.新表校验前,首先拧去箱背后锁紧螺钉,将机芯抽出,检查表内各零部件,应完整无缺。 2.检查切换开关及调节旋钮,应切换转动灵活。 3.轻敲仪表外壳,指针移动偏差不应超过其允许基本误差之半。 4.如果仪表后部已装调节器,还应检查
QXJ-313B pneumatic single-two-pin recording regulator, due to reliable performance, easy observation and recording, without the needles to achieve “manual-automatic” undisturbed switching characteristics, therefore, widely used in petroleum, chemical companies and research institutes Automatic control system. Based on actual experience and relevant information, summarize the adjustment methods and steps are as follows. First, the appearance of the inspection 1. The new form before calibration, first twist off the back of the box to lock the screw, the movement out, check the table of the parts should be intact. 2. Check the switch and adjust the knob, it should be switched to rotate flexible. 3. Tap the instrument case, the pointer movement deviation should not exceed half of the basic error allowed. 4. If the regulator is fitted on the rear of the meter, check also
