§162.050-17. Separator test rig.
46 C.F.R. § 162.050-17
This section contains requirements for test rigs used in approval testing of separators. A diagram of a typical test rig is shown in Figure 162.050-17(a).
Each mixture pump on a test rig must—
Be a centrifugal pump capable of operating at 1,000 revolutions per minute or more;
Have a delivery capacity of at least 1.5 times the maximum throughput at which the separator being tested is designed to operate;
Have a maximum delivery pressure that is equal to or greater than the maximum influent pressure at which the separator is designed to operate; and
Have either bypass piping to its suction side or a throttle valve or orifice on its discharge side.
The inlet piping of the test rig must be sized so that—
Influent water flows at a Reynolds Number of at least 10,000;
The influent flow rate is between one and three meters per second; and
Its length is at least 20 times its inside diameter.
Each sample point on a test rig must meet the design requirements described in Figure 162.050-17(d) and must be in a vertical portion of the test rig piping.
