Claims (4)
- 屋内の排水源から下水本管へ通じる排水管路中に介装される排水圧送ポンプの水位検出装置であって、ポンプ吐出口を下水本管へ通じる排水管路に接続し、屋内の排水源から導下された排水導管の終端部は吸込配管を経由してポンプ吸込口に接続し、上記吸込配管の管壁から竪孔を形成するよう気筒を垂直に立設し、該気筒内を上記吸込配管内と連通させ、該気筒の上面に筒内空気圧の受圧孔を設け、検知部が該受圧孔内へ向くようにして圧力センサーを気筒の上面に定着させ、圧力センサーと接する上記受圧孔の周縁部に気密性を保有させることにより、排水導管内の水位に応じて変化する該気筒内の空気圧変化が圧力センサーの検知部で検知され、該検知された空気圧変化を排水導管内の水位に置換判定し得るよう構成したことを特徴とする、排水圧送ポンプの水位検出装置。
- 請求項1記載の排水圧送ポンプの水位検出装置において、気筒の内周壁面が上方に向って狭くなる截頭円錐状のテーパー面に形成されていることを特徴とする、排水圧送ポンプの水位検出装置。
- 請求項1または2記載の排水圧送ポンプの水位検出装置において、気筒が上流方向へ傾斜していることを特徴とする、排水圧送ポンプの水位検出装置。
- 請求項1ないし3のいずれかに記載の排水圧送ポンプの水位検出装置において、気筒の下端内周面と連なる竪孔の下面孔周縁に円弧状の面取が施されていることを特徴とする、排水圧送ポンプの水位検出装置。
