A method of cleaning a cylinder head using pressurized fluid and a tooling assembly for the same includes a jet ignition insert attached to a spark plug well defined by the cylinder head. The insert defines an opening in fluid communication with the spark plug well. The insert includes an end wall attached to the insert distal end to close one end of the opening and the end wall defines holes. The tooling assembly includes a tool configured to clean the insert. A first engagement surface of the insert and a second engagement surface of the tool engage each other to form a seal that surrounds the holes of the insert such that the pressurized fluid is directed through the holes and into the opening of the insert during the first operation procedure of the tooling assembly to flush debris out of the holes of the insert.

A self-cleaning negative-pressure ejector at least comprises a suction chamber, a jet pipe and a flushing member. A side wall of the suction chamber has at least one suction port for communicating with a first fluid pipeline. An exit port of the jet pipe is disposed in the suction chamber and ejects a second fluid so that a negative pressure is generated in the suction chamber, a first fluid in the first fluid pipeline enters the suction chamber, and a first included angle is between a direction in which the first fluid being sucked into the suction chamber and an ejection direction of the second fluid. The flushing member optionally provides a third fluid to flush the suction chamber and/or the first fluid pipeline.

The disclosure includes a system comprising a first chamber having pressurized gas, a compressor connected to the first chamber (which may be a bladder), and a second chamber connected to the first chamber. The second chamber includes contents. The system also includes an exit from the second chamber. The pressurized gas from the first chamber travels into the second chamber to force the contents out of the exit of the second chamber. The compressor increases the pressure of the gas in the first chamber.

Various automated cleaning systems for internal cavities of pressure instruments are disclosed. The systems comprise a computer controlled fluid flow system that enables the use of various cleaning fluids for cleaning internal cavities of pressure instruments to high cleanliness levels. Various pressure instruments, including complex shapes such as Bourdon tube gauges, are accommodated. The system can include a computerized cleaning cycle selection and a multi-fluid combination of cleaners for efficient and low cost cleaning solution. A servo controlled agitation system can allow for filling, evacuation, and drying of aqueous solutions as well as high performance solvents for Oxygen Clean service.

A digitally controlled current to pressure converter (CPC) is provided. A digital CPC utilizes a digital controller and an onboard pressure transducer to accurately control the output pressure based upon an input analog control signal. The digital controller includes an anti-silting algorithm that provides an impulse movement of the three-way rotary valve of the CPC to loosen and flush away silt contamination from the valve. A redundant seal stack including an intermediate passage to the hydraulic drain ensures a low pressure drop across the outboard seal minimizing the potential for leakage and improving reliability of the CPC. The digital controller also includes redundancy and fault management algorithms that enable the use of multiple inputs and feedback signals for control of the CPC. Master/slave operation and transitioning is also provided by the digital controller.

The present invention provides methods and apparatus for cleaning and sanitizing potable water devices/appliances by recirculating and pulsing a rejuvenation solution through the device/appliance using a portable apparatus comprising a mechanical pump fluidly connected to the device/appliance.

In order to meet the objectives described above, the present invention provides a robot for detecting breakdown of NORM (Naturally Occurring Radioactive Materials) in a production system, in order to plan operations to remove scale containing radioactive material, and for decommissioning subsea system operations. The fields of application are the area of flow assurance and reservoir management, using operations to chemically remove scale containing NORM in the production system, and to improve the safety of the decommissioning processes of production systems. The invention allows the position of the scale inside the production system to be safely detected, such as, for example, the beginning of the deposit inside a production line, the extension of the deposit, and the end of the deposit, as well as whether the deposit occurred at different points along the production line.

A method for cleaning and/or disinfecting a milk-carrying system of a coffee machine for producing coffee mix drinks, and a coffee machine for carrying out the method has the aim of allowing the entire milk-carrying system to be cleaned, completely and in a way that can he easily automated. The milk delivery line is separated from the milk container, for carrying out the cleaning Process, and is connected to a first container, and a second container is arranged under a milk outlet of a milk preparation device of the milk-carrying system. Fluid is then delivered to fluid inlet in order to convey the active cleaning and/or disinfecting substance through the milk delivery line and a milk outlet into the second container. Thereafter, water is conveyed to the air inlet and the fluid inlet is closed, in order thereby to flush the milk-carrying system.

The invention relates to a method for cleaning equipment with a hollow sealed circuit and can be used in industry for cleaning equipment from salt measures, oil deposits, including asphalt paraffin, tar deposits and biological deposits. The claimed method of cleaning the inner surface of the equipment with a hollow sealed circuit consists in pumping a washing solution through an internal cavity of the said circuit with an unsteady flow regime created by local stops of the washing solution flow at the moment of oxygen or carbon dioxide gas formation, characterized by an intensity at which the pressure in the gas bubble moments of time, namely when the bubble grows, exceeds the pressure of the wash solution. The embodiment of the claimed method allows, while maintaining the cleaning efficiency, to significantly simplify its implementation and further expand the scope of use.

A method of cleaning a component within a turbine that includes disassembling the turbine engine to provide a flow path to an interior passageway of the component from an access point. The component has coked hydrocarbons formed thereon. The method further includes discharging a flow of cleaning solution towards the interior passageway from the access point, wherein the cleaning solution is configured to remove the coked hydrocarbons from the component.
