Unfortunately , the engine room was incommodious , resulting in the air inlet muffler too close to the generator unit and making it inconvenient for maintenance staff to perform operation . in a spirit to avoid such an awkward situation and save the investment on muffling treatment , we suggest the following solution be adopted in future construction of engine rooms 例如我们以前治理过的某个油机房其进风口外为防火通道,不能占用,进风消音器只能安装在油机房内,而油机房内部空间设计又过小,就造成进风消音器距发电机组过近,维护人员操作起来很不方便。
