Claims (4)
- 吸込口および吐出口と、断面真円形の雄ねじ形ロータおよびこのロータが嵌挿される開口断面長円形の雌ねじ孔を有するステータを備えた一対の一軸偏心ねじポンプ本体と、これらのポンプ本体を挟んでその中間位置に配置される駆動モータ部とから構成し、
両側の前記各ポンプ本体は回転中心軸に対するロータの偏心量および偏心方向がそれぞれ等しくなるように設定し、
前記駆動モータ部は、そのモータロータの両側面中心部に前記ポンプ本体の左右の前記ロータを一体回転可能に連結し、かつ前記モータロータの半径方向への変位が許容されるように両側の前記ステータにより回転自在に支持したことを特徴とするダイレクト駆動式偏心ねじポンプ装置。 - 両側の前記各一軸偏心ねじポンプ本体におけるロータの捩れ方向を相互に逆向きに設定し、各ポンプ本体の先端側開口から被移送液を吸い込むか吐出するかし、前記各ポンプ本体間に設けた開口より被移送液を吐出するか吸い込むかすることを特徴とする請求項1記載のダイレクト駆動式偏心ねじポンプ装置。
- 両側の前記各一軸偏心ねじポンプ本体におけるロータの捩れ方向を同じ向きに設定し、前記モータロータの中心部付近に前記両側のポンプ本体間を連通する貫通路を設け、一方の前記ポンプ本体の先端側開口から被移送液を吸い込み、前記貫通路を通って他方の前記ポンプ本体の先端側開口から吐出することを特徴とする請求項1記載のダイレクト駆動式偏心ねじポンプ装置。
- 前記モータロータの両側中心部外周にスラストベアリングを環状に配設したことを特徴とする請求項1〜3のいずれか記載のダイレクト駆動式偏心ねじポンプ装置。
