Abstract: A multiple flexible high pressure fluid cleaning lance drive apparatus includes at least a first drive motor having a first drive shaft, a spline drive roller mounted on the first drive shaft, a plurality of cylindrical guide rollers extending parallel to the spline drive roller, an endless belt wrapped around the spline drive roller and the plurality of guide rollers, and one or more follower roller modules each supporting a plurality of follower rollers for pressing against a single flexible lance. Each follower roller module independently presses its follower rollers toward the endless belt to grip the flexible lance sandwiched therebetween. Each module has an elongated block shaped housing having a central axis, a plurality of pneumatic cylinders and a piston rod carried in each pneumatic cylinder supporting a pair of spaced follower rollers that ride on the flexible lance captured between the endless belt and the follower rollers.

Abstract: A system and an apparatus for positioning a plurality of flexible cleaning lances includes a frame removably fastened parallel a tube sheet of a heat exchanger. The apparatus includes a smart lance tractor drive for advancing and retracting one or more lance hoses through one or more lance guide tubes into tubes penetrating through the heat exchanger tube sheet, a controller, one or more AC induction sensors on the tubes operable to sense holes in the tube sheet, and a tumble box connected to the controller operable to generate electrical power to the AC induction sensor from an air pressure source, supply electrical power to the controller and distribute pneumatic power to pneumatic motors for positioning the tractor drive on the positioner frame. The tractor drive includes sensors for detection of mismatch between expected and actual lance positions and automated drive reversal operation to remove blockages within tubes being cleaned.

Abstract: An apparatus for positioning a flexible lance drive device in registry with an opening into a heat exchanger tube sheet includes a flat plate bracket adapted to be bolted parallel to a flange of the heat exchanger. The bracket carries a stub tube fastened to and extending normal to the flat bracket. A rotary drive is removably fastened to the stub tube and has a rotary disc rotatable in a plane parallel to the tube sheet. A slotted box rail has a proximal end clamped to the rotary disc and a linear drive assembly is removably fastened to the slotted box rail. A guide tube collet block assembly clamped to the linear drive assembly removably supports a flexible lance drive and guide tube to guide a flexible lance between the lance drive and a selected one of a plurality of tubes penetrating through the heat exchanger tube sheet.

Abstract: A frame apparatus for holding a flexible lance positioning mechanism adjacent to and spaced from a heat exchanger tube sheet includes an upper guide rail, a lower guide rail, a positioner rail supported from one of the upper and lower guide rails and guided by the other of the upper and lower guide rails, and a rail clamp assembly fastened to a portion of a tube sheet. This rail clamp assembly has a flat plate member fastened to the tube sheet, a base plate spaced from the flat plate by one or more threaded shafts, and one or more clamp fingers rotatably fastened to the base plate. Each clamp fingers is operable to rotate toward the base plate when the base plate is drawn against the flat plate or beam member by rotating the threaded shaft, thus drawing the rail securely to the flat plate of the clamp assembly.

Abstract: A pneumatic power generator configured for generating less than about 100 W for providing on demand power to a device connected to the power generator includes a pneumatic motor coupled to an alternator with a coupling member. The pneumatic motor has an inlet port configured to receive pressurized gas to rotate an output shaft. Rotation of the output shaft is transmitted to an inlet shaft of the alternator via the coupler member. As the pressurized gas causes the pneumatic motor, the inlet shaft of the alternator rotates to produce AC power. An electronics housing is coupled to the alternator and has an electronic board and at least one power storage device. The electronic board includes a rectifier configured to convert the AC power output from the alternator into DC power for storage in a power storage device, with power being provided from the power storage device on an on-demand basis.

Abstract: A nozzle assembly comprises a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; and a switching valve cartridge disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and direct fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold. The cartridge comprises a cylindrical cartridge case having a front portion and a cup shaped rear portion, a cylindrical poppet slidably disposed within the cup shaped rear portion of the cartridge case, and a biasing member within the cartridge case between the front portion of the case and the poppet urging the poppet away from the front portion of the cartridge case.
