The centrifugal pump experiment table comprises a volute, an impeller, an inlet plate, a spindle and a motor, wherein the volute and the inlet plate are combined to form an overflowing area of a centrifugal pump; a water inlet is formed in the inlet plate; the spindle penetrates through ...
Modern performance drives often incorporate an active front end (AFE) utilizing active devices instead of passive rectifiers for the line connection for two reasons. 1.) to address the harmonic content the drive imparts on the grid. A 3-phase bridge of active devices can synchronize with the...

Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. More than 60 sets precision machines incl. CNC center, boring, milling, lathing, etc., and more...
Another type of vacuum degassing is found in the agricultural industry. In this process, a mixture of water and soil is pulled into a containment vessel by means of a vacuum pump. Centrifugal force is brought to bear on the containment vessel while the pump maintains a constant vacuum inside...
PURPOSE:To suppress deformation of a cylindrical face outward and inward by detecting number of revolutions of a drum, regulating a vacuum suction in response to the number of revolutions, and balancing a centrifugal force acting on the cylinder face with a negative pressure in a hollow chamber....
