Abstract
An automated heat exchanger tube cleaning assembly and system are provided. The present system can automatically (without ongoing human intervention) survey the tube sheet of a heat exchanger in three-dimensions, convert and record the survey results as a digital file in three-dimensions, and then, according to sequential parameters input via custom software, automatically coordinate via computer one or more cleaning devices to effect the cleaning of each desired tube of the heat exchanger.
Claims19
An apparatus for cleaning the insides of a plurality of tubes on the tube sheet of a heat exchanger, the apparatus comprising:
- a plurality of tube cleaning lances at least partially disposed within the insides of the respective tubes of the heat exchanger;
- and a tube cleaning lance rotating device comprising a plurality of pulleys driven by a single belt, the single belt and plurality of pulleys both being disposed within a housing, wherein the pulleys manipulate the rotational motion of the tube cleaning lances.
An apparatus for cleaning the insides of a plurality tubes on the tube sheet of a heat exchanger, the apparatus comprising:
- a plurality of tube cleaning lances at least partially disposed within the insides of the respective tubes of the heat exchanger;
- and a tube cleaning lance rotating device comprising a first series of pulleys driven by a first belt and a second series of pulleys driven by a second belt, the belts and pulleys being disposed within a housing, wherein the pulleys manipulate the rotational motion of the tube cleaning lances.
