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.
When local exhaust ventilation is absent, general (dilution) ventilation shall be maintained at a minimum of 10 air changes per hour, under negative room pressure, and shall be sufficient to reduce air contaminants to an acceptable user level. A supply and return system must exist in each area that is partitioned off as a separate room.
Motor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. Selection procedures and examples are given. Selection Procedure First, determine certain features of the design, such as drive mechanism, rough dimensions, distances moved, and positioning period.
