在投入使用的时候,阀块上有一个电磁阀的切换声音很大,几乎跟敲桌子敲门的声音似的,这样的声音正常么? we confirm that an intense noise is normal and therefore ok.. Following should be considered: · The noise level of valves itself could vary due to tolerances 1、根据公差范围,阀的声音会有上下波动。 · It is possible that noise is increased by installation method 2、有可能由于安装的方法而造成阀的声音变大 · Low environmental noise due to low speed of train in relation to valve noise gives a different noise feeling 3、由于列车运行速度慢,环境噪音小,这样可使阀的声音有不同的感受。 · With passengers the noise feeling will be different 4、乘客对该声音的敏感度会不同 |
