摘要： An online cleaning system for tube and shell heat exchangers is presented. The system includes a positioner, a plunger, an umbilical cleaner, and a motor. The cleaning system cleans the tubes while the heat exchanger remains in operation. The cleaning system locates and isolates a single tube via rotating and translating mechanical actions and inserts the umbilical cleaner into the tube, which may clean the tube via rotational movement or via sonication. The cleaning system may further clean the outer surface of the tubes of the heat exchanger.
