The Sizing & Selection of Hydrocyclones

The correction for pressure drop is shown in Figure 7 and can be calculated from Equation 5. As indicated, a higher pressure drop would result in a finer separation and lower pressure drop in a coarser separation. C 2 = 3.27 x 25% of the cyclone diameter to a maximum-0.28 (Eq. 5) Where C 2 = Correction for influence of pressure drop. = Pressure

HYDROCYCLONES

Due to this complexity many authors have produced correlations for both the separation efficiency and the pressure drop in hydrocyclones. Reviews have been published by Bradley (1965) and Svarovsky (1984). The centrifugal force that is generated is capable of separating particulate solids down to around 5 to 10 microns in size. The smaller the diameter of the cyclone the

Hydrocyclone Feed Pump & Pressure PSI vs Operating Parameters

07/08/2015 For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation.. First

It can be seen, when A1, A2, B1, ε and α do not change, that a bigger M will have a more uniform pressure drop. However, the influence of ζ c is nonlinear. Only when ζ c takes an intermediate value, a uniform pressure drop can be

Pressure drop in pipe fittings and valves equivalent

It should be remembered though that in the laminar flow regime velocities tend to be very low, making the velocity head (v 2 /2g) low and since the pressure drop is calculated as the product of the K value and the velocity head, the effect of the increase in K is partially offset and the pressure drop can be low in absolute terms.
