壳体压降流量特性曲线，按ISO3968 Pressure drop flow characteristic curve of shell, according to ISO3968

壳体特性曲线适用于密度为0.86kg/dm3,且运动粘度为30mm2/s的矿物油。这种情况下，压降与密度成比例变化 The shell characteristic curve is applicable to the density of 0.86kg/dm 3 And the kinematic viscosity is 30mm 2/ S mineral oil. In this case, the pressure drop varies in proportion to the density.

滤芯压降流量特性曲线 Filter element pressure drop flow characteristic curve

滤芯特性曲线适用于运动粘度为30mm2/s的矿物油 Characteristic curve of filter element is applicable to kinematic viscosity of 30mm 2/ Mineral oil of s

压降与粘度成比例变化 Pressure drop changes proportionally to viscosity

特定流量Q下，每种过滤器通过滤芯的压降需分下列两步确定 Under specific flow Q, the pressure drop of each filter through the filter element shall be determined in the following two steps

1） 整个过滤器的总流量Q除以n等于每个滤芯的流量”。n=滤芯数量 The total flow of the whole filter Q divided by n equals the flow of each filter element ". N=number of filter elements

2） 读出确定的流量时单个滤芯的压降，此压降即为通过过滤器滤芯的总压降 The pressure drop of a single filter element when reading the determined flow is the total pressure drop through the filter element
