Determination of specifications of double cylinder high pressure filter
Shell pressure drop flow curve
VKCH30
VKCH60/110
VKCH160/240
VKCH330/500/660
Filter element pressure drop curve
The pressure drop characteristic curve of the filter element is suitable for mineral oil with a kinematic viscosity of 30mm²/s, and the pressure drop changes in proportion to the viscosity.
Selection example
formula
ΔP total = ΔP shell + ΔP filter element × (viscosity mm²/S÷30mm²/S)
For example:
Flow 150L/min, precision 10u, 46# hydraulic oil
Selection VKGH330
ΔP shell=0.84bar, ΔP filter element=0.46×(46mm²/S÷30mm²/S)=0.7
ΔP total==0.84+0.7=1.54bar
