摘要： Impeller bearings for pumps are disclosed. An example fluid pump includes a motor, a shaft coupled to a rotor of the motor, an impeller coupled to the shaft forward of the motor, the impeller including blades to pump a fluid, a first radial bearing positioned around the shaft aft of the motor, a second radial bearing positioned around the impeller, and guide vanes extending radially from the second radial bearing upstream of the blades of the impeller.

摘要： Example pump systems having dual-function annular heat exchangers are disclosed. An example pump system to pressurize a fluid within a closed loop transport bus includes a pump to move the fluid, a conduit in fluid connection with the pump, a heat exchanger positioned around at least a portion of the conduit, the heat exchanger to receive a first electrical signal transmitted in a first direction at a first time and a second electrical signal transmitted in a second direction at a second time different from the first time, the second direction opposite the first direction.
