Multi-hose flexible lance tube cleaning system

摘要

A multi-hose flexible lance tube cleaning apparatus for cleaning the interior of heat exchanger tubes, the apparatus having a spool and means for rotating the spool. A plurality of tubular flexible lances are reeled on the spool assembly. Each flexible lance is in communication with a high pressure fluid source and is adapted to fit within a heat exchanger tube. The flexible lances advance into the interior of the heat exchanger tubes as the spool is rotated to reel out the flexible lances and as the high pressure fluid exits the jetting tips of the flexible lances. The cleaning apparatus also includes tube guides to guide and support the flexible lances and further includes a positioning assembly for positioning the flexible lances in substantial alignment with the heat exchanger tubes.
