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.

A modular fluid jet attack system provides a system and method for both the containment of spreading flames and extinguishing a fire. A fluid jet system delivers high pressure fluids and abrasive materials to cut a hole in a wall. After the hole is cut, a firefighter can selectively stop the flow of abrasive material to provide fluid only for fire suppression using small droplets on the order of 150 microns. The fluid jet system can employ a gas system to tactically deliver a gaseous agent to aid in a military or law enforcement operation, or to deliver a gaseous agent for use in a firefighting operation, such as an electrical fire. Portions of the fluid jet system, the gas system and the attack system can be mounted in or on a vehicle, trolley, or case for portability.

A vapor abrasive blast system includes a compressor for generating compressed air, a water pump for pumping a water stream to a pressure vessel to pressurize the pressure vessel. A control valve is disposed upstream of the pressure vessel and is configured to control the flow of water from the water pump to the pressure vessel to thereby control the flow of blast slurry downstream out of the pressure vessel.

A translatable, ultra-high pressure liquid jet system includes a translatable frame configured to maintain mechanical contact with a rail. The liquid jet system includes a liquid jet processing head affixed to the frame and configured to maintain a distance from the rail and provide a liquid jet that contacts the rail. The liquid jet system also includes an ultra-high pressure liquid pump in fluid communication with the liquid jet processing head. The ultra-high pressure liquid pump is configured to supply pressurized liquid to the liquid jet processing head.

A hydrodynamically optimised mixer module to be coupled to a deterministic hydrodynamic tool for pulsed polishing of optical surfaces, which is arranged such that the supply of abrasive foam or fluid may be interrupted without impairing the operational stability of the polishing process and of the hydrodynamic tool. The mixer module includes at least one interrupter element for interrupting high-velocity fluids; a first inlet through which air is injected under pressure and in a controlled manner; a second inlet through which a polishing fluid is injected in a controlled manner, said polishing fluid filling a previously calculated space with an optimised hydrodynamic shape and being transferred to a mixing zone where, together with the pressure-injected air, the abrasive foam is produced that is injected into a module of at least one rotational acceleration chamber of the hydrodynamic tool.

The invention is directed toward a mobile wet-abrasive blasting system used for cleaning, preparing surfaces, removing coatings, and other abrasive blasting applications. The wet abrasive basting system has a blast pot that includes pilot-controlled pneumatics to control the loading, pressurizing, de-pressurizing, and wash down functions. The wet-abrasive blasting system also uses a floating bung in conjunction with a vent mechanism to further automate the pressurizing steps in setting up the system. The wet-abrasive blasting system also uses pilot-controlled pneumatics to decide the blasting function options of just water, just air, or water/abrasive mix and air. Wet-abrasive blasting systems mix an abrasive media with water and convey the mix to meet compressed air and direct through a blast hose and nozzle.

The invention relates to a method for adjusting or operating a particle-metering system for a particle blasting installation, in particular a blasting installation for the working of surfaces, the abrasive throughput of which is preset by means of a passing-through opening that can be varied on the basis of time and/or variables and is determined by means of a downstream throughput sensor as a throughput sensor signal (DS), wherein the throughput sensor signal (DS) is used for controlling a manipulated variable (SG) for the degree of setting of the passing-through opening, wherein to adjust the metering system for at least one value of the manipulated variable (SG) the actual throughput (D) through the passing-through opening is determined by means of a measurement of the weight of abrasive material (M) allowed through within a defined time period (Dt), and the manipulated variable (SG), the actual throughput (D) and the corresponding throughput sensor signal (DS) are stored in an assignment table, wherein the relations between the actual throughput (D), the manipulated variable (SG) and the throughput sensor signal (DS) are used during subsequent operation.
