Abstract:
An apparatus for ultra high pressure waterjetting, comprisinga pressure receiver having a top opening and a bottom opening, the periphery of the bottom opening having a sealing surface for vacuum adhering the pressure receiver to a deck surface, the pressure receiver also having an air flow regulator;a nozzle manipulator mounted in the top opening of the pressure receiver, the nozzle manipulator being rotatable about multiple axes in the top opening and having a passageway;a rotational tubing extending through and being in sliding fit with the passageway of the nozzle manipulator, the rotational tubing having a first end and a second end, wherein the rotational tubing is capable of sliding movement within the passageway of the nozzle manipulator;a rotating swivel mechanism having a top end and a bottom end, the bottom end being connected to the first end of the rotational tubing and disposed outside the pressure receiver, wherein the rotating swivel mechanism is capable of imparting rotation to the rotational tubing, the top end of the rotating swivel mechanism having a pump connector for attachment to a hose from a water pump;an ultra high pressure nozzle body connected to the second end of the rotational tubing and disposed inside the pressure receiver, wherein the ultra high pressure nozzle body is capable of vertical movement above and below a plane formed by the bottom opening and is capable of swinging movement through an arc of approximately 90 degrees within the pressure receiver, the nozzle body also being capable of rotational movement due to the attachment to the rotational tubing, the ultra high pressure nozzle body also having a plurality of orifices in the perimeter; anda vacuum attachment connected to a wall opening in the vacuum chamber for controlling flow from the vacuum chamber.
