摘要:
A magnetofluidic suspension turbine combines a fluidic bearing and a magnetic circuit comprising a magnet in the stator and an airgap defined between polepieces of a ferromagnetic circuit between the rotor and the stator. This ferromagnetic circuit includes facing centering members on opposite sides of the airgap.

A machine with an on-board supply tank for spraying a coating material. In one embodiment, the spraying machine includes a carriage (3) supporting an arm (4) with an end-mounted holder containing a tank (6) for supplying a spray nozzle (8). The arm further includes a coating material changing assembly (9) which is translatably movable towards the holder (5) to effect mutual engagement between quick connection units (12, 13) during cleaning/filling of the tank (6). The machine is useful for forming coatings consisting of an electrically conductive material.
摘要:
In a process and device for spraying a coating product onto an article from a sprayer to which coating product is supplied from a reservoir equipped with a piston which is moved along a path in order to transport the coating product to the sprayer, movement of the piston is controlled as a function of movement of the sprayer relative to the article.
摘要:
An electrostatic coating product spraying device comprising: at least one sprayer having an electrostatic charging mechanism; and a support structure supporting the at least one sprayer, the structure including elements which are at ground potential, wherein the support structure includes an electrostatic shield positioned and arranged so that the electrostatic charging mechanism is located between the electrostatic shield and an object to be coated. The electrostatic shield is maintained at a potential differing from ground potential.
摘要:
A coating product sprayer device forms an overhead or lateral machine including a member carrying at least one sprayer mobile relative to objects to be coated and at least one lateral gantry carrying this member, which is adjustable in position in an opening in a front of the gantry. This member is moved up and down and/or with a lateral tracking movement by at least one coupling member such as a drive belt. At least one sealing panel closes off at least part of the opening and is fixed to one such flexible coupling member.
摘要:
A device for delivering a finely divided coating product to a sprayer. The device includes a conveyer composed of a tube and a worm screw mounted in the tube for transporting the coating product, and a motor coupled to the worm screw for rotating the worm screw. The device is constructed for limiting the torque which must be transferred from the motor to the worm screw for rotating the worm screw.
摘要:
An installation particularly suited to use in the automobile industry for electrostatic application of conductive coating product is partly at a high-tension voltage and partly grounded, these parts being separated by at least one temporary insulating device. The electrostatic sprayer is fed from a first storage tank insulated from ground and the latter is filled in a very short time period with coating product previously stored in a grounded second storage tank, through a temporary insulating device.
摘要:
In an electrostatic paint spraying installation or the like, a high-tension voltage generator comprises a voltage rectifier-multiplier in a mobile subsystem and a grounding connection in a fixed subsystem. A conductive wire connects an input terminal of the voltage rectifier-multiplier to the grounding connection. When the high-tension voltage generator operates, a high-frequency alternating current residual signal injected into this conductive wire is sensed and measured. The measured value is compared against a reference value that may be variable. The high-tension voltage generator is disabled if the difference between the measured value and the reference value reaches or crosses a predetermined threshold.
摘要:
A process and station for changing product in an installation for spraying coating product, by bringing a first reservoir towards a suitable area of a cleaning/filling station, separating a sub-assembly composed of the first reservoir and a first spray associated therewith, with respect to the robot, connecting with the robot a second, similar sub-assembly composed of a second reservoir and a second spray, adapted to be used for spraying coating product during cleaning and/or filling of the first reservoir and the first spray, and proceeding with cleaning and/or filling of the first reservoir and the first spray in the area.
摘要:
A method and device for monitoring operation of a high voltage generator which converts an input voltage into an output voltage which is higher than the input voltage, by measuring at least one first physical quantity which is representative of the input voltage; deriving at least one parameter from the at least one measured first physical quantity; comparing the at least one parameter with a second measured physical quantity which is representative of the magnitude of the output voltage; and producing a response when a predetermined minimum differential exists between the at least one parameter and the second measured physical quantity.
