【実用新案登録請求の範囲】[Scope of utility model registration request] 被流送物が吸い込まれる吸込室に突出する駆動
軸端部の軸封部の略中間位置に環状溝を形成して
、該環状溝の両側にパツキングリングを配装し、
前記吸込室内をゴム素材等からなる弾性スリーブ
により内室とその周囲の等圧室に分割し、該等圧
室と前記環状室とを接続管により連通させて圧力
伝達媒体としての固形物非含有の液体を充填した
ことを特徴とする流送用ポンプの軸封装置。 An annular groove is formed approximately in the middle of the shaft sealing portion of the end of the drive shaft that protrudes into the suction chamber into which the transported material is sucked, and packing rings are arranged on both sides of the annular groove,
The suction chamber is divided into an inner chamber and a surrounding equal pressure chamber by an elastic sleeve made of a rubber material, etc., and the equal pressure chamber and the annular chamber are communicated with each other by a connecting pipe, so that no solid matter is contained as a pressure transmission medium. A shaft sealing device for a flow pump, characterized in that it is filled with a liquid.
