Operating Pumps at Slower Speeds Increases Reliability

Bearing Life: Bearings are the second leading cause of pump failures, and ball bearing fatigue life (typically called "L-10" life) is inversely proportional to shaft speed. In addition, bearing loads drop as the square of the pump speed, and bearing life is inversely proportional to the cube of the bearing loads.

Turbocharger Failure Analysis: What Went Wrong and How …

Sometimes a broken thrust bearing is paired with broken thrust rings. If the turbo match is not good or the turbo operates often in a surge condition, this can hammer the thrust bearing and break it. While a turbocharger can typically stand up to occasional brushes with surge and normal pressure differentials, frequent problems will indeed cause a failure.

Risk vs. Reward: When it Comes to Oil Pumps, Knowing …

• Sometimes a low oil pressure problem isn't the oil pump or internal leaks, but a combination of loose bearing clearances and the wrong oil for the application (too thin). If the engine was built with relatively loose bearing clearances for a race car, it will require a thicker viscosity motor oil (20W-50, straight SAE 30, 40, 50, etc.) to maintain good oil pressure.

Figure 3 presents energy consumption of a variable-displacement pump during pressure holding when operating in both variable- and constant-speed modes. The measurement shows that the energy consumption during variable-speed operation is affected mainly by pressure-dependent volumetric losses in the pump, while increasing the pressure had little effect on the current-related losses in the ….
