Title:
HORIZONTAL CHANNEL TYPE PUMP
Document Type and Number:
Japanese Patent JPS5738693
Kind Code:
A
Abstract:
In a lateral channel pump, the rotor blade compartments of a ring of blades in the rotor alternate in length, toward the center of the rotor, between long and short rotor blade compartments. The associated lateral channel has an outer contour concentric with the center of the rotor and an inner contour which tapers helically towards the outlet port. At the inlet point of the lateral channel, a partial circulating current is separated from the main circulating current as a result of the longer blade compartments. The partial current, due to its higher speed, causes the main current to circulate more rapidly between the rotor blade compartment and the lateral channel. As a result, the main current is accelerated and a higher level of efficiency is obtained.
