Sand Vacuum Technology - aquacristal

Vacuum Return Sand Pump Technology Oilfield . In vacuum sand pump column, the sand sucked in cavity is pumped to sand sitting tube under the weight of column. 3. In conventional column, it costs a long time to separate water and sand. The sand pumping rate is low. In vacuum return one, the mixture of water and sand is pumped to sand sitting tube and be separated slowly there. Read More++. Use ...

01/01/2013  One was a series of tests on pore-air pressure distributions in dry sand slopes, and the second series involved dry sand slope stability tests. The results revealed that a vacuum (negative pore-air pressure) even as small as −0.4 kPa significantly increased the stability of the model slopes with dimensions of 0.9 × 0.5 × 0.28 m (length × width × height). The pore-air pressure ...

Titanium Casting with Sand Foundry Techniques: Journal

A centrifuge is used within the furnace vacuum chamber during the pouring of the melt. The high g forces during the casting operation help overcome the lack of fluidity. The centrifuge action assists in filling mold cavities with metal densities vastly superior to those from conventional sand foundry static casting.
