挤压机操作压力设计值为15mpa，而计量泵前压力要求大于3mpa才能满足熔体的计量要求。若加装预过滤器必然会增加熔体从挤压机出口至计量泵入口总压力降，考虑到一般熔体预过滤器的操作压差为5mpa左右，如对于一系列总压力降将达到△p1+5.0mpa=12.5mpa,即使将挤压机操作压力设定为操作上限15mpa进行生产，也不能满足计量泵前压大于3.0mpa的要求。其中二系列由于管线堵塞.挤压机出口至第二箱体计量泵入口处压力降已达到12mpa，若加装预过滤器，将无法满足生产对计量泵前压的要求。

故若保证操作压力要求则必须更换原生产线熔体管线。同时，若加装熔体预过滤器可以起到熔体混合作用，为保证减少熔体压力损失决定对原熔体管线进行重新设计。4、改造前，将组件中过滤网的材质由原多目数金属网形式改为过滤精度达到25um的金属烧结毡，在二系列进行试验，结果说明可以较大幅度提高机台运行平稳率，证明我们的分析是正确的，加装熔体预过滤器增加过滤精度，可以解决存在问题，同时确定熔体预过滤器的过滤精度可以定为25um。5、为保证稳定控制，原挤压机出口处控制挤压机转速的压力表应移至加装的熔体预过滤器之后，并在生产时调整该控制压力的设定值
