Abstract: An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The apparatus monitors drive roller/belt position and actual hose position, compares the belt (expected travel) to hose position (travel) and generates a position difference, or mismatch. If the mismatch is above a predetermined level, the drive motor direction is reversed for a predetermined time interval, and forward operation restored after the predetermined time interval; and the sequence of repeating the reversing and restoring operations is continued until the position difference or mismatch no longer exceeds the predetermined difference threshold.

Abstract: A nozzle assembly includes a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; a switching valve assembly 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; and a flow insert configured to replace the switching valve assembly for directing flow through all of the ports when switching functionality is not needed. This flow insert may be made of a low pressure material such as a polymer.

Abstract: A compact flexible lance propelling apparatus is disclosed that is mountable on a pipe end. The apparatus includes a drive mechanism, an adaptable support that can be fastened directly to the pipe end which carries the drive mechanism, a remote control console, and a hose take-up drum spaced from the drive mechanism. The drive mechanism includes a driven roller and a follower roller sandwiching the flexible lance hose therebetween and a rotary cam lift mechanism for linearly raising the follower roller to permit insertion of the flexible lance hose and lowering the follower roller against the driven roller.

Abstract: A speed retarding device for a rotary nozzle includes a hollow cylindrical housing and a rotatable tubular shaft rotatably carried by the housing. The shaft has a central axial bore and an enlarged drag sleeve portion carried in the housing. A pair of support bearings support the drag sleeve portion of the shaft in the housing. An annular inner seal between each of the support bearings and the drag sleeve portion defines a cavity within the housing receiving a viscous fluid confined within the cavity. The drag sleeve portion includes a peripheral helical groove and a plurality of axial bores extending therethrough parallel to the central bore, one or more blind axial bores each having a closed end an open end, and a piston disposed in each of the one or more blind axial bores each defining an air space between the closed end and the piston.

Abstract: A lance drive support apparatus is adapted to be fastened directly to a heat exchanger tube sheet adjacent a selected number of tubes to be cleaned. One embodiment includes an angled flat base plate having an inner center corner, an outer center corner, a first outer end corner and a second outer end corner, a support post adjacent each outer end corner, and the inner center corner fastened at one end to the base plate, and a top plate fastened to an opposite end of each support post. An extensible scissor arm assembly pivotally fastened to the inner center corner post can position a lance drive mechanism at a distal end of the scissor arm assembly at precise X and Y coordinates adjacent the tube sheet. The precise X and Y coordinates are determined by positions of X and Y cylinders connected to a common scissor arm assembly extension hinge.

Abstract: A process for assembling a coil clad hose includes suspending a spring wire helix between carriages mounted on a rail, rotating one of the ends of the helix to expand the helix, inserting a hose through the expanded helix, contracting the helix onto the hose, installing an end fitting onto each end of the hose, fixing one end of the helix together with the ferrule and the hose at one end of the hose, adjusting a pitch of the helix along the hose to another end of the hose, and fixing the helix and the hose together with the ferrule at the another end of the hose. The apparatus includes a rail, a pair of carriages movably supported on the rail, each of the carriages having a through bore holding a tang clamp bushing therein, and a pair of cable clamp fixtures mounted one at each end of the rail.

Abstract: A guide tube pitch adjustment apparatus for aligning distal ends of lance guide tubes in registry with tube openings in a heat exchanger tube sheet is disclosed. A guide tube pitch clamp assembly carried within and supported from a housing. The pitch clamp assembly has at least two V-blocks fastened to a threaded rod. One V-block is fastened to a portion of the threaded rod having right hand threads, and another V-block is fastened to another portion of the threaded rod having left hand threads. Each of the V-blocks supports a portion of one of the guide tubes, and a cross bar clamp within the housing is oriented to span across the V-blocks and adjustably hold the portions of the guide tubes in a spaced relationship such that spacing between the distal ends of adjacent guide tubes may be adjusted by rotation of the threaded rod.
