笔者在近年来的加气机检定中,发现一些在工作中应注意的问题,在这里和大家一起探讨。一、检定前准备目前,加气机检定采用的多是以加气机现场检定装置进行“标准表法”检定。在将设备运输到现场后,应按照要求预热10min以上,并且由于在汽车载卸的过程中,质量流量计无可避免的会产生振动,也需要一定时间使其静止,以避免在检定中产生误差。在等待过程中可以进行检查加气机外观、查询加气机各项参数、连接地线等一些准备工作。
In recent years, author author test in the filling machine, found that some should pay attention to the work of the problem, here and we discuss. First, the pre-test preparation At present, test machine used to test mostly with the filling machine on-site test device “standard table ” test. After the equipment is transported to the site, the equipment should be warmed up for more than 10 minutes as required. And since the mass flow meter will inevitably vibrate during the loading and unloading process of the vehicle, it will take some time for it to be stationary to avoid being checked Produced error. In the waiting process can check the appearance of filling machine, filling the parameters of the filling machine, connecting the ground and some other preparatory work.
