Prediction of Leakage from an Axial Piston Pump Slipper ...

Oil leakage between the slipper and swash plate of an axial piston pump has a significant effect on the efficiency of the pump. Therefore, it is extremely important that any leakage can be predicted. This study investigates the leakage, oil film thickness, and pocket pressure values of a slipper with circular dimples under different working conditions.

US5884776A - Dynamic classifier with hollow shaft drive ...

A dynamic classifier for a coal pulverizer has an improved drive mechanism which is mounted on top of a pulverizer and concentric with the classifier axis of rotation and is directly controllable. The drive mechanism is a variable-speed DC or AC electric motor having a hollow motor shaft. The motor can produce classifier rotor rotational speeds of between 50 and 200 rpm.

Pulverizer Fineness and Capacity Enhancements at Danskammer

Dynamic classifiers were retrofitted at Central Hudson Gas & Electric's Danskammer Station to increase the capacity and improve the fineness of the existing pulverizers. The dynamic classifiers, which went on line in April 1995, replaced the existing static centrifugal cone type classifiers in CE Raymond Mills.
