TLDR
In this paper, a group of full-circumferential-flow pumps has been proposed to pump a fluid at a small rate under a low pump head and a high pump head.Abstract:
A group of full-circumferential-flow pumps has a group of motors each comprising a main shaft, a rotor mounted on the main shaft, a stator disposed around the rotor, a cylindrical outer motor frame fitted over the stator, and an outer cylinder disposed around the cylindrical outer motor frame with an annular space defined therebetween, a group of pump parts oriented in opposite directions to meet different directions in which the main shafts of the motors rotate, and a group of frequency converters for energizing the motors to rotate at high speeds In order to meet rating requirements including flow rates and pump heads, the group of motors, the group of pump parts, and the group of frequency converters are combined to provide a group of single-suction-type full-circumferential-flow pumps that are powered by a commercial electric power supply and belong to a first type for applications to pump a fluid at a small rate under a low pump head, and a group of single-suction-type full-circumferential-flow pumps that are rotatable at high speeds and belong to a second type for applications to pump a fluid at a small rate under a high pump headread more
