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 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: Embodiments of a threaded component locking apparatus for preventing inadvertent disconnection of the male and female connection are disclosed. One embodiment includes an annular groove around the male member spaced from its threads and a ring shaped retainer disposed in the annular groove. A rear lip on the female threaded component interferes with the ring shaped retainer to prevent loosened connection between the components from becoming completely disconnected. Another embodiment utilizes a C-clip retainer member to limit loosening of the connection. Another embodiment utilizes a canted spring ring to interfere with and limit loosening of the connection. Another embodiment has a pair of collar halves that fit around the male member each having an annular groove for receiving a canted spring ring or ring shaped retainer to interfere with a rear lip on the female threaded component to limit loosening of the connection.

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 an enlarged drag sleeve portion carried in the housing and a shaft end extending through at least one end of the housing to receive a rotary nozzle thereon. 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 support bearings are separated from the cavity confining the viscous fluid and an outer annular seal on the shaft adjacent each support bearing prevents environmental contamination such as water and debris from entry into the support bearings.

Abstract: A system and an apparatus for positioning a plurality of flexible cleaning lances includes a frame removably fastened parallel to a row of tubes in a tube sheet within a domed end of a heat exchanger. A chassis support member is mounted on the frame for movement in an X direction. A chassis having spaced apart parallel box rail members is movably mounted on the chassis support member for movement of the chassis in a Y direction. A rotary arm extends from the chassis, and a flexible lance guide hand fastened to a distal end of the rotary arm is configured to maintain a plurality of flexible lance guide tubes in parallel alignment with the row of tubes irrespective of an angle between the rotary arm and the frame. The system may include a lance drive and a snout connected between the lance drive and the positioning apparatus.

Abstract: An apparatus for retarding rotation of a nozzle includes a hollow housing, a rotary shaft within the housing, a rotatable rotor on the rotary shaft free to move axially along the shaft, and a cam assembly coupling the rotor and shaft together in the housing such that rotor rotation on the shaft causes the cam assembly to displace the rotor axially on the shaft in a first direction. A set of springs on the shaft biases the rotor in a second direction opposite the first direction on the shaft. Finally, a viscous fluid disposed between the rotor and the housing generates a drag on rotor rotation with the shaft. Relative rotation of the rotor with respect to the shaft in conjunction with a variable gap between the rotor and housing are used to slow and thus control rotary nozzle speed.

Abstract: A flexible lance drive device is disclosed that has, in a compact housing, a drive motor between an inner and an outer wall, a linear array of pairs of driven upper and lower drive rollers outside the outer wall coupled to the drive motor via shafts extending through both of the inner and outer walls. Each driven roller is fastened to its shaft via a quick release device. A drive sprocket is fastened to each shaft outside the inner wall. The drive motor is coupled to each of the drive sprockets via a serpentine belt carried outside the inner wall. The lower driven rollers are rotatably carried by the inner and outer walls. The upper driven rollers are rotatably carried by a block positioned between the inner and outer walls and coupled to the lower driven rollers by a pair of parallel links releasably biased by a piston driven linkage.

Abstract: A flexible high pressure fluid cleaning lance drive apparatus includes a guide rail having a longitudinal axis adapted to be positioned within a boiler water box and aligned in a fixed position with respect to a central axis of the water box. A tractor drive module is mounted on the guide rail, a helix clad high pressure fluid hose drive module is mounted on the guide rail operable to propel a flexible lance helix clad hose through the drive module along an axis parallel to the guide rail longitudinal axis, and a right angle guide rotator module is mounted on the guide rail and connected to the tractor module for positioning a rotatable high pressure nozzle carried by the helix clad hose within a guide tube attached to the rotator module.
