为电力部门研制的气动基地式高温液位指示调节仪中,我所采用了用高温耐蚀弹性合金和高温恒弹性合金制成的扭力管元件作为检测液位的弹性元件。其工作介质为450℃过热水蒸气。为了解元件性能,专门制造了一套光学力矩-转角测试仪。该设备的加热装置最高温度可达700℃,可用于对扭力管的高、低温性能测试。通过分析计算,证明该测试装置具有一些优点,如可放大转角,无摩擦,附加传动误差小,装调方便。在传动误差计算实例中,其附加误差小于0.02％。对多根元件的高温及常温性能测试的结果表明,该
In the pneumatic base type high temperature liquid level indicator developed by the electric power department, I used the torsion tube element made of high temperature corrosion resistant elastic alloy and high temperature constant elastic alloy as the elastic element for detecting the liquid level. Its working medium is 450 ℃ superheated steam. To understand component performance, a set of optical torque-angle tester has been specially manufactured. The device’s heating device up to a maximum temperature of 700 ℃, can be used for torque tube high and low temperature performance test. Through the analysis and calculation, it is proved that the test device has some advantages, such as magnification of rotation angle, no friction, little additional transmission error and convenient assembly and adjustment. In the transmission error calculation example, the additional error is less than 0.02%. The multi-element high temperature and ambient temperature performance test results show that this
