Abstract: A system and method for cleaning of heat exchanger tubes including an assembly, an indexer and a communication device provided with specialized software and programming. The indexer includes orthogonally arranged first and second arms. A trolley and sensors are provided on the indexer arms. One or more lances are provided on the trolley to deliver water jets into the openings. Sensors measure displacement as the trolley is moved relative to the heat exchanger's face plate. An operator controls the system from a distance away using the communication device. During setup, the pattern of the face plate is learned and mapped utilizing information from the sensors as one of the inputs. This information is utilized to help navigate the face plate during a subsequent cleaning operation. A kit for retrofitting existing X-Y indexers is also disclosed.

The propulsion device, upon the pressure sensing device detecting a pressure crossing a threshold value, propels the cart in the reverse direction for predetermined distance or time before again propelling the first cart in the forward direction.

Abstract: An apparatus and method for cleaning a surface. The apparatus includes a frame having wheels and a handle extending outwardly therefrom. A disc plate assembly is mounted on the frame for rotation about a first vertical axis and a nozzle assembly is mounted on the disc plate assembly for rotation about a second vertical axis. The disc plate assembly is rotated at a lower speed than the nozzle assembly. Separate pneumatically-operable motors drive the wheels, the disc plate assembly and nozzle assembly. A skirt extends downwardly from the frame and outwardly from nozzles on the nozzle assembly. The nozzles may be raised or lowered relative to the surface to be cleaned. Fluid is delivered from a fluid source to the nozzles and a vacuum port is provided on the frame to enable dirty fluid to be removed from a chamber bounded by the skirt.

Abstract: A hose reel assembly, system and method for cleaning tubes, particularly heat exchanger tubes, which system includes independently rotatable inner and outer drums. The inner drum is rotated in a first or second direction by a first motor assembly to wind a hose disposed in a gap between the drums, off of or onto the inner drum. A second motor rotates the outer drum causing rotation of a nozzle on the hose about the hose's longitudinal axis and at speeds of about 100 to about 1600 rpm. The nozzle delivers a water jet at pressures of up to about 55,000 psi to cut through deposits in the bores of the exchanger tubes. The nozzle is mounted on an indexer movable within the heat exchanger and a camera and joystick on a remote console enables an operator to view the cleaning operations and manipulate the nozzle in relative safety.

Abstract: The present invention provides a system and method for wirelessly controlling a water jet machine by way of a wireless connection between the water jet machine and a computing device.

Abstract: A high velocity cutting nozzle for connection to the fluid supply tube of a high pressure fluid cutting system. The nozzle includes a housing which threadably connects to the fluid supply tube for receiving pressurized liquid therefrom. A bushing disposed within the housing sandwiches a removable sleeved jeweled orifice disk therebetween at a spray outlet bore of the housing. The bushing includes a flow directing bore with a convergent inlet portion for reducing turbulence, and an outlet portion having an annular cylindrical or divergent inner surface, and an annular convergent angled or curved end surface. The sleeved orifice disk is in co-axial fluid communication with the flow-directing bore and a spray outlet bore of the housing to facilitate fluid flow. The sleeved orifice disk fits within a sleeve receiving bore in the bushing immediately downstream of the flow-directing bore abutting a shoulder of the bushing.
