Title:
BRANCHED DUCT CONSTRUCT AND UNIAXIAL ECCENTRIC SCREW PUMP SYSTEM
Document Type and Number:
Japanese Patent JP2011208537
Kind Code:
A
Abstract:

To provide a branched duct construct which branches a fluid into the desired number of branches, can dispose the discharge section of each branched duct at a desired position, and can equalize the discharge pressure and discharge quantity at each branched duct, and also provide a uniaxial eccentric screw pump system having the branched duct construct.

The branched duct Bn of this branched duct construct includes n relay sections Rn so as to correspond to each of n discharge sections Fn. The branched duct further includes: n systems of introduction-to-relay section ducts SRn that connect an introduction section S to the relay sections Rn; and n systems of relay-to-discharge section ducts RFn that connect the n relay sections Rn and n discharge sections Fn. Also, in the branched duct construct, the relay sections Rn are disposed at positions corresponding to the points obtained by dividing, into n parts, the circumference of a virtual circle the center of which is at a point on a vertical straight line extending through the axis of the introduction section S, and the branched duct Bn is formed in a manner so that the lengths of the n systems of relay-to-discharge section ducts RFn are equal to each other.
