    摘要： 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 head.

    摘要： A full-circumferential flow pump includes a motor having a stator, a shaft rotatably disposed in the stator, and a rotor mounted on the shaft for rotation relative to the stator, an outer frame barrel disposed around the stator, an outer cylindrical pump casing disposed around the outer frame barrel with an annular space defined therebetween, and a pump assembly mounted on an end of the shaft for pumping a fluid into the annular space or pumping a fluid introduced from the annular space. The full-circumferential flow pump further includes an inner casing provided in the outer cylindrical pump casing for accommodating the impeller and a resilient seal disposed between the outer cylindrical pump casing and the inner casing for preventing a pumped fluid in the outer cylindrical pump casing from leaking towards a suction side of the impeller.

    摘要： A pump control system has a pump unit composed of a turbo pump, a motor for operating the turbo pump, and a frequency/voltage converter for generating a frequency and a voltage to energize the motor. The rotational speed of the turbo pump is varied in order to equalize the current of the motor to a constant current irrespective of the head of the pump. The pump can be operated to take fully advantage of the current capacity of the motor.
