Definitions

  • the present invention relates to a machine comprising a chassis enclosing at least one functional element and a control unit, and equipped with a fluid compressor, and more particularly a high-speed fluid compressor.
  • the fluid compressors equipping such machines are generally called turbochargers or centrifugal compressors. They are equipped with a stator and a rotor forming a permanent magnet synchronous motor (brushless motor). Compressors of this type can reach very high speeds, for example from 100,000 to 500,000 revolutions / minute. The motor drives the turbine at high speed, the turbine compressing the fluid.
  • the fluid can be air, water, a gas, a refrigerant or any other suitable fluid.
  • These compressors are used in many industrial, medical, pharmaceutical, food, automotive applications, particularly for the supply of compressed air, or refrigeration, heating or air conditioning applications, for the supply of compressed fluid.
  • compressors are generally used in very large installations, the compressor being far from the equipment requiring compressed fluid.
  • the compressed fluid is supplied by means of a supply circuit provided in the network.
  • this supply circuit is long, which entails risks of leakage of fluid along the circuit. Leaks in a compressed air circuit cause pressure losses, which generates very significant financial losses.
  • the network is kept under pressure at all times in order to be able to respond rapidly to the need of the equipment.
  • the continuous operation of the compressor represents a significant electrical energy consumption.
  • the motor shaft is rotatably mounted on a frame by means of two axial bearings.
  • These bearings may include ball bearings.
  • ball bearings it is difficult to obtain rotational speeds with such bearings because of the difference in speed between the balls and the rings.
  • the balls used are ceramic, the life of such bearings is limited to a hundred hours because of high rotational speeds.
  • Other types of bearing may be used, such as aerodynamic bearings.
  • this type of bearing has the disadvantage of moving transversely at the time of starting or during a change of speed, which creates friction at the level of the bearing elements.
  • the compressors are usually lubricated with a lubricant.
  • the disadvantage is that the lubricant may mix with the fluid, so that the compressed fluid is polluted by the lubricant.
  • impurities present in the central network may mingle with the compressed fluid. This is particularly dangerous, for example in the case of medical applications, such as dental applications, for which the compressed air arriving in the mouth must be healthy.

Any connection of the machine to a compressor belonging to a central network is deleted. Thus, the circuit for supplying the compressed fluid to the functional element is very short. This reduces on the one hand the risk of leakage, and on the other hand avoids the pollution that may occur during the transport of compressed fluid through a central network. This also allows a very fast reaction time of the compressor, so that the latter can operate only at the request of the functional element.

  • the machine according to the invention can be used in many applications, such as industrial applications, medical, pharmaceutical, food, automotive, including for the supply of compressed air, or refrigeration applications, heating or air conditioning, for the supply of compressed fluid.
