Description
【発明の詳細な説明】 本発明は旋流型タービンメータに関する。[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a swirl type turbine meter.
旋流型タービンメータは、短管状の筐体内に同
軸に上流側及び下流側にデフユーザを設け、且つ
このデフユーザを支承する整流翼列を螺旋状のブ
レードで構成し、デフユーザの周りに同軸に螺旋

デフユーザの間に回動自在に支承した回転タービ
ンを回動させ、この回動タービンの回転数を検知
して流動を測定するものである。 A swirl-flow turbine meter has differential users disposed coaxially on the upstream and downstream sides within a short tubular housing, and a rectifying blade row that supports the differential users is composed of a spiral blade. A flow is generated, which causes a rotary turbine rotatably supported between upstream and downstream differential users to rotate, and the flow is measured by detecting the rotational speed of the rotary turbine.
この旋流型タービンメータで用いる回転タービ
ンは、管軸に平行なブレードから成る環状翼列を
有するものである。 The rotary turbine used in this swirl-type turbine meter has an annular blade row consisting of blades parallel to the tube axis.
このため、回転タービンのブレードに作用する
流体抵抗がタービンの回転方向に分力を有しない
ので、整流翼列のブレードが管軸に平行な、所謂
直流型タービンメータにみられるレイノルズ数ハ
ンプと呼ばれる現象が無いため、タービン回転運
動の安定性が高く広いレイノズル数範囲に渡つて
高精度が維持されるという特徴を有する。 For this reason, the fluid resistance acting on the blades of the rotating turbine has no component force in the direction of rotation of the turbine, so the blades of the rectifier blade row are parallel to the tube axis, which is called the Reynolds number hump seen in so-called DC turbine meters. Since there is no phenomenon, the turbine rotational motion is highly stable and high accuracy is maintained over a wide range of Raynozzle numbers.

に高められないという問題があつた。 However, this swirl type turbine meter has
Although it is difficult to manufacture a spiral straightening blade row that generates a swirling flow, and the straightening blade row must sufficiently subdivide the flow path cross section, it is difficult to construct such an annular blade row. Because it was extremely difficult to do so, the number of blades that make up the annular blade array was actually small, and secondary flow due to centrifugal force etc. was generated in the flow path defined by the blades. This caused the problem that the spiral flow was disturbed and the accuracy could not be sufficiently improved.
本発明は、叙上の観点に立つて成されたもので
あつてその目的とするとことは極めて容易、且つ
