Pumping effect on particle sizes in a recirculating aquaculture ...

Centrifugal pumps are widely used to continuously move water to and from filtration devices in recirculating fish culture systems. The smaller the particle size, particularly below 60–100 μm, the more difficult and costly it is to remove particulate materials. Minimizing the production of small particles reduces the overall amount...

Effect of Pump Pulsation and Particle Loading on ... - Levitronix

Three types of pumps (diaphragm, bellows, and centrifugal) with varying degrees of pulsation were tested at similar average flow rates and backpressures. The magnitudes of the flow pulsations from each pump type were measured at all test conditions. Particle retention by 0.1 μm membrane filters was characterized as a...

Particle pumping characteristics were compared between pumping from the inner side private flux region (IPP) and pumping from both sides of the private flux region (BPP) in the JT-60U W shaped divertor, and between JT-60U IPP and pumping in the DIII-D lower baffled divertor. The pumping flux for BPP is smaller than...

The pump acceleration mechanism - IOPscience

Abstract. Starting in the early 2000s, Fisk and Gloeckler developed a theory for a pump acceleration mechanism to account in detail for the ubiquitously observed, so-called, -5 spectra, a distribution function that is a power law in particle speed with spectral index of -5. To date, this theory has seen no general use in...

How to select the correct slurry pump based on particle size

2017年7月4日 ... The wear of centrifugal slurry pumps in mineral processing and hydrotransport can be quite severe, and is one of the major cost concerns for plant operators. Understanding the influence of slurry particle size on wear is essential to maximising the life of centrifugal pumps operating in mineral processing...
