In the case of the power jet, for 100 GPM applied to the venturi jet, it only sucked 50 GPM through the nozzle and dredge-hose. I repeated the test 5 or 6 times and the results were always the same. The suction nozzle drew 75 GPM and the tri-jet drew 90 GPM. I expected an efficiency of 100 GPM applied to the jet and sucking 200 GPM, with a ...
Apr 16, 2014· I have the basic design figured out, can anyone give me the ratio of the size of thewater inlet line to the suction line size? Also pressure/gpm needed to be effective?Ive got a 40 drop and going from 3 to 1 1/2 line size to run my Simple Simon.Im hoping to run a 2 suction nozzle/power jet. :hmmm...
A Common Suction Gold Dredge Design A dredge is powered by a motor and pump A common misperception is that gravel is sucked through the pump The pump actually pumps only water, which is delivered to a venturi type device (called a power jet or a suction nozzle) which indirectly creates suction in a larger hose

In normal operation a gold dredge is run by an operator at the intake nozzle who directs the nozzle and who captures and discards oversized rocks that would plug the intake hose.
First you have to decide if you want a suction nozzle or power jet type. The suction nozzle puts the high-pressure water in right at the nozzle. A power jet puts the high-pressure water in just before the sluice box. A suction nozzle is best in very shallow water; a power jet produces better overall suction. Most dredges are power jets, but ...

The real key to making this design work, is the entire dredge is flooded with water and material, with almost no air bubbles and zero riffles. By the time the gold travels from the Suction Nozzle to the Nugget Trap, the gold has settled to the bottom of the tube.
Mar 29, 2019· In total I built 4 different pvc nozzle designs 2 were regular jet nozzles, a 1" discharge and 1 1/2" discharge and two infinity jet nozzles a 1" discharge and a 2" discharge. The last infinity nozzle worked the best and is the largest of the bunch and probably one I'll keep and test with my little Honda powered 90 gpm gas pump.

K 1 is largely influenced by the pump suction nozzle approaching the impeller eye. To confirm values of K 1, a pump was modified by installing area reducing steel plates in the suction approach as shown in Figures 8-13, 8-14, 8-15, and 8-16.The plates were first formed in wood conforming to existing suction nozzle core box shape, then manufactured in steel and welded in place.
