Abstract
A compact, speed-increasing thrust module which (i) installs as a unit in a horizontal pump system to replace the standard thrust chamber which would otherwise be used, (ii) allows the horizontal pump system to operate at an optimum speed outside of the pump motor rating, (iii) reduces the number of pump stages required, (iv) thereby reduces the overall size, weight and cost of the system, (v) reduces complexity, and (vi) reduces the time and costs for installation, leveling and component alignment.
Claims7
A speed-increasing thrust module which installs as a unit in a horizontal pump system, the speed-increasing thrust module comprising:
- a module support bracket, plate, or frame;
- a thrust compartment provided on or in the module support bracket, plate, or frame;
- a speed-increasing gear compartment provided on or in the module support bracket, plate, or frame;
- a first gear in the speed-increasing gear compartment which is driven by an input shaft;
- a speed-increasing gear in the speed-increasing gear compartment which is driven by the first gear, the speed-increasing gear having an outer diameter which is less than an outer diameter of the first gear;
- an output shaft which is driven by the speed-increasing gear and extends through one or more thrust bearings in the thrust compartment;
- a lubricant in the thrust compartment;
- and
- a lubricant cooling system comprising
- a heat exchange element,
- a pump which circulates the lubricant through the heat exchange element,
- a fan which blows air through the heat exchange element to cool the lubricant, and
- the fan being mounted on the input shaft.
