A hose shroud comprises a tube formed from an aramid fabric rolled into a plurality of tubular layers. The hose shroud has a first end fitting at a first end of the tube, and a second end fitting at a second end of the tube.
A nozzle for use in a high pressure water jetting system is provided including a stationary housing, a rotating shaft, and a central passage within the shaft for communicating high pressure fluid to the nozzle. The shaft may include communication passages to provide fluid from the central passage to a forward fluid pressure chamber defined between an outer peripheral surface of the shaft and the housing. A rear fluid pressure chamber may be defined between the shaft and the housing and a restriction may be defined between the housing and the inlet end of the shaft, the restriction configured to receive fluid from the rear fluid pressure chamber and transport it to a chamber communicating with the atmosphere. The restriction may be formed as an annular gap between the housing and the inlet end of the shaft and configured to decrease in volume when the shaft moves axially forward.

An automated cleaning system according to an exemplary aspect of the present disclosure includes, among other things, an X-Y positioning system configured to position a lance guide relative to an element to be cleaned. The X-Y positioning system is remotely operated. The system further includes a lance in communication with the lance guide, a drive system configured to drive the lance relative to the element to be cleaned, and a reel configured to manage a slack in the lance.
This disclosure relates to a spray cleaner head for a cleaning system. In one aspect of this disclosure, the spray cleaner head includes a gear system configured to regulate rotation of a nozzle, and the gear system includes a central bore receiving an inlet shaft. In another aspect of this disclosure, spray cleaner head includes an adjustable brake assembly configured to selectively regulate rotation of the nozzle. In yet another aspect of this disclosure, the spray cleaner head includes first and second seals provided axially between the first and second bearings.

A fluid nozzle for use in a high pressure water jetting system includes a housing to be fixed to a source of high pressure water. The housing receives a rotating member and an inner peripheral bore. The rotating member includes a shaft received within the housing, and a nozzle extending outwardly of the housing, the nozzle having openings extending along a direction having a component both forwardly along an axis of rotation of the shaft and the nozzle, and radially outwardly relative to the central axis. A central passage within the shaft communicates high pressure fluid to the nozzle. The shaft includes leakage paths to provide leakage fluid from the central passage to an interface between an outer peripheral wall of the shaft and an inner peripheral wall of the bore in the housing. The leakage paths communicate fluid to a forward fluid pressure chamber, and to a rearward fluid pressure chamber. A pressure loss to the rearward fluid pressure chamber is greater than a pressure drop at the forward pressure chamber.
A rigid lance cleaning system includes rigid tubular lances that are movable between retracted and extended positions for delivering a cleaning fluid. Flexible hoses are connected to respective rigid tubular lances for delivering the cleaning fluid. A hose reel is configured to dispense the flexible hose when the rigid tubular lances extend and collect the flexible hoses when the rigid tubular lances retract. A frame movably supports the rigid tubular lances and a drive system is configured to selectively extend and retract the rigid tubular lenses.

An improved seal for use in fluid systems such as a water jet system includes an outer seal point that is very close to an inner seal point. By spacing these two seal points very close together, the force on the seal is greatly reduced compared to the prior art. In the disclosed embodiment, the outer seal point is on an angled forward face of the seal that abuts a back-up ring angled face. The inner seal point is between the seal and an internal shaft which rotates relative to a housing.
