在检定工作中,我们发现不少的压力表报废或不合格并非本身的质量不好或使用中的正常损耗,而是由于强烈的震动造成的。这种情况既影响了压力量值的准确,又不利于安全生产和工艺控制,危害极大,应当引起重视。一、产生震动的原因 1.周期检定时往返途中的颠簸; 2.被测介质产生的脉冲或冲击负荷; 3.压力表使用在有激烈震动的场所; 4.人为的意外撞击。二、对压力表的影响 In the verification work, we found that many of the pressure gauge scrapped or failed is not its own poor quality or normal wear and tear, but due to strong vibration caused. This situation not only affects the accuracy of the pressure magnitude, but also not conducive to safe production and process control, endangering great, deserves attention. First, the reasons for the occurrence of vibration 1. Cycle check the bumps along the way; 2. The measured medium pulse or impact load; 3. Pressure gauge used in a place with intense vibration; 4. Accidental human impact. Second, the impact of the pressure gauge
