A method and apparatus for cleaning, and removing contaminants from the interior of a lubrication rundown tank of a mechanical system provides a source of pressurized and heated cleaning fluid containing at least one solvent; a first jumper hose communicating between the source of pressurized cleaning fluid and the interior of the lubrication rundown tank; a second jumper hose communicating between the interior of the lubrication rundown tank and a dirty fluid collection body; and an outlet spray nozzle carried by a nozzle extension placed within the interior of the lubrication rundown tank and in fluid communication with the source of pressurized and heated cleaning fluid to receive the pressurized and heated cleaning fluid therefrom.

A spray nozzle, which in some embodiments has a body and a deflector, the body having a fluid passageway and an outer wall including a plurality of fluid-flow orifices therethrough in fluid communication with the fluid passageway and spaced at least partly circumferentially around the outer wall, where the deflector is disposed at least partly circumferentially about and radially outwardly of the body in fluid communication with the plurality of fluid-flow orifices, and the body includes slots and fingers spaced at least partly circumferentially about the deflector. Some embodiments include a second deflector. In some embodiments, each finger and slot has a configuration that defines, at least in part, a flow trajectory, and the flow trajectory defined, at least in part, by one finger or slot is different from the flow trajectory defined by another finger or slot.

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.

The tank cleaning system can include a trailer having a support base transportable by a vehicle, and an arm movably mounted to the support base for movement relative to the support base. The arm can be operable to extend into the space to perform a cleaning operation inside the space.

A vehicle mounted garbage bin cleaning system including power takeoff includes a pair of arms configured for lifting a garbage bin, the pair of arms rotatably coupled to a mount on the vehicle, a hopper configured for accepting the garbage bin when the pair of arms lifts the garbage bin into the hopper, at least one spray rod extending upwards from the hopper, said spray rod including a water nozzle, wherein when the pair of arms lifts the garbage bin into the hopper, the spray rod is situated within the garbage bin, a hydraulic pump mechanically coupled with a transmission of the vehicle, such that the transmission drives the hydraulic pump, a hydraulic motor hydraulically coupled with the hydraulic pump, a pressure washer pump mechanically coupled to the hydraulic motor, the spray rod fluidically coupled with the pressure washer pump.

A containment tank assembly is described that includes a tank including an inner surface and a cleaning apparatus mounted to the tank. The cleaning apparatus includes an elongate arm and a rotary spray head assembly rotationally coupled to an end of the elongate arm. A rotating nozzle assembly is rotationally coupled to the rotary spray head. A magnetic field source is coupled to the rotary spray head so as to generate a spatially changing magnetic field in accordance with a rotation of the rotary spray head assembly in relation to the end of the elongate arm. A magnet field sensor is carried in a fixed relation to the elongate arm. The magnetic field sensor, in operation, generates a sensor signal that varies in accordance with the spatially changing magnetic field in accordance with the rotation of the rotary spray head assembly.
