Sewer cleaning device comprises suction ejector whose air intake creates vacuum in first tank into which liquid is induced, ejector operated by water jet delivered by water circuit

摘要

The pipework cleaning device comprises suction means which comprise an ejector (10) whose air intake (110) creates a vacuum (D) in a first tank (20) on which a first end (201) of a flexible pipe (200) is connected. The pipe second end (202) induces a liquid (L). The ejector is operated by means of a pressurized water jet (P) delivered by a closed water circuit (3) whose tank comprises a second tank (30) isolated from the first tank.
