摘要： Embodiments of arc plasma cutting torches are disclosed. In one embodiment, an eccentric plasma cutting torch includes an upper portion and a lower portion. The lower portion is angled on one side along a length λ which results from continuously smaller cross sections of the lower portion which are biased towards a non-angled side of the torch. As a result, a central axis of an electrode of the torch, used for cutting, is biased by an offset from a central axis of the upper portion towards the non-angled side of the torch. Such an offset allows for a torch tip region of the torch to get closer into otherwise difficult-to-access portions of workpieces for cutting. Furthermore, the overall dimensions of the torch are configured such that cooling elements within the torch dissipate enough heat to keep the torch in a stable operating condition during a cutting operation.

摘要： A consumable set is provided that is usable in a plasma arc torch to direct a plasma arc to a processing surface of a workpiece. The consumable set comprises a nozzle and an alignment surface. The nozzle includes: 1) a nozzle body defining a longitudinal axis extending therethrough, and 2) a nozzle exit orifice disposed in the nozzle body for constricting the plasma arc. The nozzle exit orifice defines an exit orifice axis oriented at a non-zero bevel angle relative to the longitudinal axis. The alignment surface is generally parallel to the exit orifice axis and dimensioned to align the exit orifice such that the plasma arc impinges orthogonally on the processing surface of the workpiece. The alignment surface is configured to lay at least substantially flush against a guiding surface angled relative to the processing surface of the workpiece.

摘要： A plasma gas water ionization purification system that purifies waste water into clean water by removing inert waste solids from the waste water. The plasma gas water ionization purification system includes an ionization chamber and a plasma emitting device. The ionization chamber receives the waste water. The plasma emitting device is operatively connected to the ionization chamber and generates a stream of plasma to heat the waste water in the ionization chamber to generate purified steam from the waste water, thereby resulting in separation of the purified steam from the inert waste solids in the waste water, with the purified steam then being condensed into liquid form forming the clean water, which is collected for later use.

摘要： A film removal method and apparatus for removing a film from a substrate are disclosed. The method comprises the steps of disposing a plasma generator and a sucking apparatus over the substrate, projecting a plasma beam from the plasma generator onto the film obliquely, disposing the sucking apparatus on a reflection path of plasma projected by the plasma generator, and sucking a by-product of an incomplete plasma reaction occurring to the film so as to keep a surface of the substrate clean, with a view to overcoming the drawbacks of deposition of the by-product which results from using the plasma as a surface cleansing means under atmospheric conditions.

摘要： The indirect plasmatron comprises a neutrode assembly comprising a plurality of plate-shaped electrode members which are electrically insulated from each other. In its interior, the neutrode assembly defines an elongated plasma channel. The outlet aperture for the plasma torch is in the shape of an elongate slot and extends parallel to the central longitudinal axis of the plasma channel. Each of the two electrodes of the plasmatron is surrounded by a cavity through which an inert gas can be fed into the plasma channel. For the purpose of stabilizing the electric arc, at least one pair of permanent magnet members is provided. Their magnetic field exerts a force onto the electric arc which is directed opposite to the force exerted onto the electric arc by the flow of the plasma gas. Particular neutrodes are provided with a channel for feeding a further gas into the plasma channel.

摘要： The plasma gun head for plasma spraying apparatuses essentially comprises a cathode body mender, an anode body member and an insulating member inserted there between and electrically insulating these two members from each other. Inserted into the cathode body member is a cathode assembly, and into the anode body member an anode nozzle, both extending transverse to the longitudinal axis of the plasma gun head. The anode body member and the cathode body member both are provided with cooling channel sections which are connected in series as seen in the direction of flow of the cooling medium. The anode nozzle is rigidly integrated into the anode body member; thus, it is not necessary to provide sealing elements in this thermally highly stressed region. The sealing elements required for sealing the cooling channel sections are located remote from the anode nozzle and the cathode assembly, respectively, in a region, which is thermally not stressed.

摘要： A plasma spray torch comprises a spray nozzle which forms an electrode and which includes a nozzle duct, and a second electrode associated therewith, in a portion of a torch arm, which is electrically insulated from the spray nozzle. The torch arm has flow passages for a working gas and for a cooling agent, the latter flowing in one of the flow ducts to the nozzle and being removed after producing its cooling effect from another flow duct. A powder feed conduit opens into the nozzle duct. The working gas flow duct is connected to a duct which passes through the second electrode while at least in the region of its mouth opening, the nozzle duct is inclined relative to the longitudinal axis of the torch arm or the flow duct therein. In a method of internally coating a tube by plasma spraying, the torch is introduced into the tube which is then rotated and moved axially relative to the torch during the spray operation.
