Hydrocyclone Feed Pump & Pressure PSI vs Operating Parameters

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.

HYDROCYCLONES - thermopedia.com

The size and shape of the vortex finder, the shape, of the chamber into which the feed liquid is injected and the geometry of the feed inlet all dictate the details of the flow pattern which will often include recirculatory streams (see Figure 5).. Due to this complexity many authors have produced correlations for both the separation efficiency and the pressure drop in hydrocyclones.

Hydrocyclone wear and performance is highly dependent of the feed pressure and the conditions of the hydro cyclones. The pressure should never exceed 0.4Mpa, as more than 0.4Mpa will cause excessive wear on the hydro cyclones. Recommended pressure is between 0.25 and 0.4Mpa, however this will vary depending on the concentration of solids.

Effect of Variables on Water Split Behavior in Hydrocyclone

For this purpose systematic experiment was carried out with a 76 mm hydrocyclone at various operating conditions. The study reveals that out of these four variables only spigot diameter and vortex finder diameter play a significant role in water partitioning behavior but feed pressure and vortex finder length has marginal effect on water split.
