Claims (1)
裏側端面1bを非摺滑面とする固定密封環1を、回転軸
4の外周に遊合するようシールボックス内壁等に凹設せ
られた環溝3内に収容して非摺滑面を溝底面3bに当接
させると共に、固定密封環1の外周面1dと環溝内周面
3Cとの間の空隙部には緩衝バッキング6を介在させ1
.かつ、固定密封環1の内周面に焼付されて回転密封環
2の方向へ伸延する合成ゴム製リップ7の内周縁7Cが
、回転軸4と摺接して外液流人阻止面となるよう構成せ
られた水中ポンプにおける回転軸密封装置。Front end surface 1. A stationary sealing ring 1, in which a is a sliding surface facing the rotating sealing ring 2 and a back end surface 1b is a non-sliding surface, is recessed in the inner wall of the seal box or the like so as to loosely fit around the outer periphery of the rotating shaft 4. It is accommodated in the annular groove 3 so that its non-sliding surface comes into contact with the groove bottom surface 3b, and a buffer backing 6 is interposed in the gap between the outer circumferential surface 1d of the fixed sealing ring 1 and the inner circumferential surface 3C of the annular groove. Let's do it 1
.. In addition, the inner circumferential edge 7C of the synthetic rubber lip 7, which is baked onto the inner circumferential surface of the stationary sealing ring 1 and extends in the direction of the rotating sealing ring 2, is in sliding contact with the rotating shaft 4 and serves as an external liquid flow-preventing surface. A rotating shaft sealing device in a constructed submersible pump.
