Parameters for a plurality of motors that move a nozzle on a three-dimensional movement locus are set easily. A washing device 1 includes display device 7, and a worker touches an input unit 7A of the display device 7 with a finger, to thereby set parameters for both servo motors that move a nozzle 3 on a three-dimensional movement locus. Specifically, a three-dimensional model Md1 of a tank 2 to be washed is displayed on the input unit 7A, and next, the worker drags specific spots of the three-dimensional model Md1, sequentially, and selects washing methods and washing time periods of the spots. The selected contents are transmitted to a control device 6, are computed by a computing unit 6A of the control device 6, so that the parameters for both servo motors for operating the nozzle 3 in three dimensions are set in washing.

The invention relates to an apparatus and to a method for cleaning vessels. The vessel cleaning apparatus (10) has a suction lance (20) and a flushing lance (40). The flushing lance (40) is configured to receive fluid, such as cleaning liquid and/or compressed air, and to expel it against an inner wall of a vessel to be cleaned. The suction lance (20) is configured to suck off and lead off fluids present in the vessel as well as cleaning liquid supplied through the flushing lance (40) from the vessel, preferably against the direction of effect of gravity.

A method for operating a hand-held spray device, wherein in a first step a target orientation of the spray nozzle relative to the operator control unit is defined, and wherein during operation a rotation of the spray device, brought about by manual movement of the spray, through a z swinging angle, about a z axis which is orthogonal with respect to the longitudinal axis and/or through a y swinging angle about a y axis which is orthogonal with respect to the longitudinal axis and orthogonal with respect to the z axis, by a single sensor and wherein the z swinging angle and/or the y swinging angle engage as interference variables in a closed-loop control circuit and make available closed-loop control variables in such a way that the spray nozzle retains its target orientation by means of closed-loop control of the swinging mechanism.

An aerosol distributor for filter leakage detection in a gas filtration system, said aerosol distributor being configured to be positioned in a gas stream upstream of the filter, said aerosol distributor comprising: a rotatable distributor housing comprising a hub in fluid connection with two or more radial chambers evenly distributed around said hub, the distributor housing having an inlet for admitting a test aerosol from an aerosol source via the hub into the radial chambers, each radial chamber being elongated, sealed at a distal end, and provided with a plurality of outlet holes distributed along the length thereof for releasing the aerosol from the radial chamber into a gas stream surrounding the aerosol distributor, and wherein said aerosol distributor further comprises an actuator configured to rotate the distributor housing around a central axis thereof.

A sprinkler assembly with a nutating distribution plate can improve even distribution of water. The distribution plate can tilt and/or translate upon water impinging the distribution plate to disperse water in different directions. The sprinkler assembly can have a deflector assembly including the distribution plate, a stem supported by a bearing, and a contact portion upstream of the distribution plate to contact an outer race that limits a range of movement of the distribution plate. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing.

The present disclosure describes a system and method of depositing ceramic or ceramic composite coatings on the inside surface area of a tubular shape. The system and method described herein can provide an interior coating for tubes and pipes to provide wear resistance, abrasion resistance, and anti-scaling effects.

In order to create a rotating unit for a coating lance device for thermally coating an interior, it is provided that the rotary drive is implemented as a hollow-shaft motor coaxial with the axis of rotation of the tool holder, and wherein the tool holder and the coating material feed, as well as the process media feed, are located centrally relative to the hollow-shaft motor. Furthermore, in order to create a coating lance device for thermally coating an interior, it is proposed to provide such a rotating unit; at least one linear actuator for axial and/or lateral positioning of the rotating unit relative to an interior to be coated; and stationary supply connections for supplying electricity to the coating lance, and for the coating material feed, and for the process media feed.

A high pressure monitor includes an outlet body with a transverse passage, which extends through the body to form two inlets of the outlet body, and a second passage, which is in communication with the transverse passage and extends through the outlet body to form an outlet. The monitor further includes first and second bodies, with the outlet body mounted between the first and second bodies. Each of the first and second bodies has a transverse passage, which are in fluid communication with the inlets of the outlet body. A first swivel joint is provided between the outlet body and the first body. A second swivel joint is provided between the outlet body and the second body. Further, each of the swivel joints comprises a pressure balanced hydraulic fitting with seals and bearings, wherein the seals and bearings are oriented to reduce the axial pressure on the bearings from fluid flowing through the monitor.

The present invention discloses an MDOF (multi-degree-of-freedom) micro-lubrication intelligent spray head system for a CNC milling machine, comprising an annular rotating platform, a longitudinal telescopic part, a rotating part, an intelligent spray head mounting platform and an information acquisition system. The annular rotating platform comprises a rotating piece which rotates along a horizontal circumferential direction; a bottom of the rotating piece is connected with at least one longitudinal telescopic part; a lower end of the longitudinal telescopic part is connected with the rotating part; the rotating part rotates within a set angle range by taking a point connected with the longitudinal telescopic part as an axis; the intelligent spray head mounting platform is connected with the rotating part and moves along with the rotating part; and the information acquisition system is mounted on the intelligent spray head mounting platform.

A method for cleaning the cooking space of a cooking appliance with a pan including adding a cleaning agent to the cooking space and if necessary, after this agent has been allowed to work for a certain period of time, a liquid jet is introduced under high pressure from the a spray head of a cleaning device through the at least one spray nozzle, which rotates around an axis perpendicular to the rotational axis of the spray head rotating around this axis. The liquid jet consists exclusively of water and which swirls and splashes the cleaning agent, and if necessary, after this splashed agent has been allowed to work for a further certain period of time, removes the residues mechanically from the bottom, the walls, and the inside surface of the lid, and wherein said residues are then carried away together with the washing solution out of the cooking space via the drain.
