VKZH pipeline type high pressure filter series

Pipeline high-pressure filters are assembled on pressure pipes with different pressure levels. This type of filter device is used to finally eliminate impurities generated by invading waste and formed by chemical action. It is especially suitable for automatic control systems and servo control systems. It can prevent high-precision control components and executive components from being damaged or jammed too early due to pollution, thereby reducing system failures and increasing the service life of components.

Determination of filter specifications


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 (actual flow ÷ nominal flow) + ΔP filter element × (viscosity mm²/S÷30mm²/S)

For example:

Flow 300L/min, accuracy 10u, 46# hydraulic oil

Selection VKZH630

ΔP shell=1.5 (300÷630)=0.72bar, ΔP filter element=0.26×(46mm²/S÷30mm²/S)=0.4

ΔP total==0.72+0.4=1.12bar
