    Abstract: A rotary nozzle having a rotating shaft operating within a cylindrical housing is balanced by allowing passage of a small amount of pressurized fluid to be bled to an area between the outside of the opposite end of the shaft and the inside of the housing where the fluid force acts axially in an opposing direction upon the shaft to balance the axial inlet force exerted by the pressurized fluid. The balance of axial forces is self-regulating by controlling escape of the fluid through a tapered or frusto-conical region between the shaft and housing. A plurality of centrifugal weight segments around the inlet end of the shaft are thrust outwardly against the cylindrical housing to retard rotational speed while pressurized fluid around the centrifugal weight segments provides a fluid bearing between the weights and the housing.

    Abstract: A frame apparatus for holding a flexible lance positioning drive device adjacent to and spaced from a heat exchanger tube sheet includes an upper guide rail carrying a movable carriage supporting a drive positioner rail having a drive support carriage and an air motor drive assembly fastened to each of the carriages, each air motor drive assembly comprising an air motor having a shaft driving a spur gear through a worm gear reducer, wherein the spur gear is carried within a spur gear housing fastened to the worm gear reducer, and the air motor assembly is fastened to the carriage via the spur gear housing. The spur gear housing is selectively rotatable on the carriage between a locked position with the spur gear engaging the rail to which the carriage is mounted and an unlocked position with the spur gear disengaged with the rail to which the carriage is mounted.

    Abstract: A flexible cleaning lance safety apparatus is described as including a tripod support structure located close to an opening into an object to be cleaned. A flexible lance drive is fastened to the support structure for driving a high pressure fluid through a lance to the object to be cleaned. A snout tube is connected between the lance drive and an opening into the object to be cleaned. One or more micro pressure valves on each leg of the tripod support structure is operative to sense a predetermined force applied between the support structure and a support surface supporting the tripod support structure. When the predetermined force is sensed this causes the high pressure fluid to be diverted from the lance and the object to be cleaned to atmosphere.

    Abstract: A multiple flexible lance hose take-up drum apparatus or device in accordance with the present disclosure includes a base having three or more support legs and a hollow take-up drum assembly rotatably supported from the base. The drum assembly includes a hollow cylindrical shell, a bottom plate fastened to the shell, a high pressure fluid supply connection and a manifold positioned radially along a bottom plate of the shell for connection to one end of each of a plurality of flexible lance hoses. The base includes an L shaped support arm extending from the bases alongside the shell. A plurality of guide tubes are supported by the support arm and aligned over a rim of the shell for guiding flexible lance hoses into and out of the take-up drum assembly.

    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: 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 has at least one drive motor in a first portion of a housing and a drive axle projecting across a second portion of the housing carrying a cylindrical spline drive roller. A plurality of cylindrical guide rollers on fixed axles span across the second portion of the housing aligned parallel to the spline drive roller. An endless belt wrapped around the at least one spline drive roller and guide rollers has a generally smooth outer surface and a transverse splined inner surface having splines shaped complementary to splines on the spline drive roller. A bias member supports a plurality of follower rollers each aligned vertically above one of the at least one spline drive roller and guide rollers operable to press each follower roller toward one of rollers to frictionally grip a flexible lance hose when sandwiched between the follower rollers and the endless belt.
