Branched duct construct, and uniaxial eccentric screw pump system

Abstract

Disclosed is a branched duct construct that branches a fluid into a 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. Further disclosed is a uniaxial eccentric screw pump system provided with said branched duct construct. The branched duct (Bn) of the branched duct construct has n relay sections (Rn) so as to correspond to each of n discharge sections (Fn), and has: 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 aforementioned n relay sections (Rn) and discharge sections (Fn). Also, with the branched duct construct, the relay sections (Rn) are disposed at positions corresponding to n points that divide the circumference of an imaginary circle centered around a point on a vertical line passing through the center 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 each the same.

Description

technical field [0001] The present invention relates to a branched flow path structure capable of branching fluid introduced into an introduction part into a plurality of systems, and a uniaxial eccentric screw pump system having the branched flow path structure. Background technique [0002] So far, when the non-transported material (fluid) pumped by the uniaxial eccentric screw pump disclosed in the following patent document 1 is divided into a plurality of flow paths, the method of connecting the uniaxial eccentric screw pump to the Countermeasures such as branching of the flow paths one by one. Furthermore, until now, measures have been taken to stabilize the discharge pressure and discharge volume in each branch flow path by providing adjustment valves, nozzles, etc. in each branch flow path and finely adjusting each branch flow path. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2008-0175199. [0004] However, there is a problem that when b...

Problems solved by technology

[0004] However, there is a problem that when branching the flow path connected to the uniaxial eccentric screw pump as described above, the number of branches is limited to the n power of 2 ( n=natural number), so that it cannot be divided into the desired number of divergences

In addition, there is also a problem that it is more difficult to equalize the discharge pressure and discharge volume of the fluid discharged from each branch flow path in order to make the arrangement of each branch flow path arbitrarily arranged.

Specifically, there is a problem that complex adjustments such as discharge pressure and discharge volume need to be adjusted by attaching valves, nozzles, etc. to each branch flow path and fine-tuning them.

Therefore, in the prior art, there is a problem that it is extremely difficult to form a branched flow path so that the fluid is discharged to a desired position with a desired number of branches, and the design of the flow path is greatly restricted.

[0005] In addition, when taking measures to adjust the discharge pressure and discharge volume by installing valves, nozzles, etc. on each branch flow path to finely adjust them, there is the following problem: the fine adjustment of the valves and nozzles Need to be skilled, making it difficult to equalize the discharge pressure and discharge volume
