At the second location the head is changed for a second head attached to a cable and is pulled back to the first location by the hose. The nozzle is then pulled back to the second location by pulling the cable while nozzles directed along the pipe toward the second location drive the solids forwardly to the second location for extraction.

  • Patent number: 8951357
    Abstract: A device (1) comprises an intake duct (11) for taking in milk, an intake duct (15) for taking in a cleaning fluid, a central duct (13) in which both intake ducts (11, 15) are merging, and a pump (31) which is arranged in the central duct (13). Cleaning the device (1) involves filling both the central duct (13) and the milk intake duct (11) with the cleaning fluid. In particular, the pump (31) is a bi-directional pump, wherein filling the central duct (13) with the cleaning fluid is realized by operating the pump (31) in one direction while blocking the milk intake duct (11), and wherein filling the milk intake duct (11) with the cleaning fluid is realized by opening the milk intake duct (11) and operating the pump (31) in a reversed direction, wherein cleaning fluid is displaced from the central duct (13) to the milk intake duct (11).

  • Patent number: 8945317
    Abstract: An injector cleaning apparatus with a concentric dual flow introducer and a flow-dispersing injector seat along with a method of cleaning an injector. The concentric dual flow introducer has concentric cleaning fluid flowpaths configured to communicate with a central passage and a plurality of peripheral passages of a gas injector. The input-side injector engaging interface of the concentric dual flow introducer and the flow-dispersing injector seat each have a compressible sealing portion having compressibility sufficient to yield under fluid cleaning surges attributable to initiation and termination of cleaning fluid flow through the injector cleaning apparatus along with resiliency sufficient to prevent abutment of the gas injector and a rigid facing portion of the input-side injector engaging interface and output-side injector engaging interface respectively.

  • Publication number: 20150027499
    Abstract: A lancing crawler or head crawls along a no-tube lane (NTL) on a floor defining a reference plane oriented transverse to tubes of a steam generator, and has nozzles that generate lancing fluid jets along at least two different angles in the reference plane spaced apart by at least 45°. A rotational drive rotates the nozzles about an axis of rotation that may be offset from an axis of thrust imposed by the jets from the nozzles. An on-board sighting laser may be mounted with the nozzles, along with an on-board camera. A bladder expands to secure the lancing crawler or head between steam generator tubes adjacent the NTL. Each nozzle may include a taperlock seat. A nozzle tilt drive is configured to tilt the one or more nozzles respective to the reference plane.

  • Patent number: 8920575
    Abstract: Foreign matter is removed from a digital hydraulic pressure controller having two portions connectable to each other and each including two valve arrays with a plurality of individually switchable valve means having different flow cross-sections and connected in parallel within a valve array. One valve array of each pressure controller portion can connect a supply line to a controller output line and the other valve array can connect the output line to a drain line. The two pressure controller portions are connected, the valve means having the largest flow cross-section of the valve array of the one portion on the supply line side is opened, the valve means having the largest flow cross-section of the valve array of the other portion on the drain line side is opened and the opened flow path is flushed through the pressure controller with pressurized working fluid, while the other valve means are closed.
