静电斥力，从而使它们沉淀下来。 本设计中采用絮凝剂为常见的 PAM即聚丙烯酰胺。 过滤 发酵工业生产上常用的过滤设备是板框过滤机，板框过滤的目的是为了除去发酵醪液中的固形杂物和菌种。 过滤的动力是过滤板两侧的压力差，过滤速率与压力差和滤饼有关，所以常常加些助滤剂，尤其是酶制剂工业生产的发酵醪液属于非牛顿流型，粘度大，难于过滤。 助滤剂的功能助于滤渣形成钢性滤饼，保证过滤后期的顺利进行。 膜过滤

告 其可靠度为 90％。 基本额定动载荷大，轴承抗疲劳的承载能力相应较强。 在实际工况中，滚动轴承常同时受径向和轴向联合载荷，为了计算轴承寿命时将基本额定动载荷与实际载荷在相同条件下比较，需将实际工作载荷转化为当量动载荷。 在当量动载荷作用下，轴承的寿命与实际联 合载荷下轴承的寿命相同。 当量动载荷 P的计算公式是 P=XFr＋ YFa 式中 Fr径向载荷， N； Fa轴向载荷， N； X，
