近年来新设计的格栅一般都采用机械清污。但目前已建成投入运行的机械格栅中,有不少工程的运行功能不佳。如某地当年建设两座泵站,第一座泵站所选格栅型式投产后不能令人满意,第二座即另选型式并换了供货厂家,结果还是问题不少。这里除加工安装的质量外,其所选设计型式也是重要原因。为此,笔者将东南 In recent years, newly designed grilles have generally used mechanical cleaning. However, in the mechanical grids that have already been put into operation, many of them have poor operating functions. For example, when the construction of two pump stations was completed in one place, the grid type selected by the first pump station was unsatisfactory after it was put into operation. The second seat was of another type and was replaced by the supplier. The result was still a lot of problems. Apart from the quality of processing and installation, the selected design type is also an important reason. For this purpose, the author will be southeast
