此外，随来流流量和颗粒浓度的增加，过滤压降增加。
Increases in the inlet flow rate or the particle concentration both increase the filter pressure drop.
随着过滤时间的持续，饼层厚度增加，阻力增大，过滤压差随时间的持续呈直线增长。
As the duration of the filter cake layer thickness, increase, resistance increases, filtering the duration of the pressure difference with a straight-line growth.
过滤操作是在恒定的压差下进行，称为恒压过滤。
Filtration operation is in constant pressure differentials, called the constant pressure filter.
