Abstract:
1. Modular turbine casing assembly having an upstream casing element, a downstream casing element, and a turbine located between said upstream and downstream casing elements, each said upstream and downstream casing elements having a cylindrical wall defining an internal shoulder at an upstream end, and a cooperating external shoulder at a downstream end so that said upstream and downstream casing elements may be stacked, each said upstream and downstream casing elements having a turbine locator consisting of a central hub and a number of radially extending ribs coupling the hub to a circumferential rim adjacent to said cylindrical wall, each hub having a spindle extending toward the upstream end of the casing element and an opposing dimple exposed to the downstream end of the casing element, the turbine having a central hub and a number of radially extending turbine blades coupling the hub to a peripheral collar of predetermined width, the central hub having an axially extending spindle on an upstream side and a recess on a downstream side adapted to cooperate with the dimple of the upstream casing element and the spindle of the downstream casing element respectively, the turbine being adapted to be magnetized so that rotation of the turbine can be monitored electronically, and the peripheral collar having a height and diameter adapted to locate inside the cylindrical wall of the downstream casing element so that the turbine may rotate freely between the upstream and downstream casing elements.
