Definitions
- the present invention relates to a cable covered with a solid lubricant, such cable being intended to be installed in a tubular conduit.
- the equipment for depositing the lubricant should be very close to the sheath extrusion head because otherwise it is not possible to check correctly the thickness of this sheath. In any event, this equipment presents a significant size and such an arrangement is not favorable for a good dimensional control of the sheath.
- the present invention thus relates to a device for making a cable lubricated which does not significantly modify the geometrical characteristics of this cable.
- the invention therefore relates to a device for depositing a lubricant coating. on a cable, this cable comprising a sheath produced by means of an extruder followed by a cooling tank; in addition, downstream of the cooling tank, the device includes a pretreatment device followed by a deposition chamber of a lubricating material.
- This pretreatment member can be a reheating member or else then it can carry out a crown effect treatment of the cable sheath.
- the lubricating material is based on polytetrafluoroethylene.
- the lubricating material consists of microbeads.
- this lubricating material is inorganic; for example, glass.
- the deposition of the material lubricant is produced in a bath.
- the deposition of the material lubricant is produced by spraying an emulsion or by spraying with by means of a gas.
- the deposition of the material lubricant is produced by means of a calibrated die.
- the deposition chamber is followed by an evaporation member.
- the material lubricant not being granular this material is deposited by phase spraying plasma.
- the invention also relates to a method for implementing the device, this method comprising a step of reheating the cable sheath and a step of depositing a lubricating material on this sheath.
- an extruder 20 performs the cable sheath 11 from a core 10.
- the core of a fiber cable often consists of a central carrier rod, the fibers being arranged in helical grooves formed on the periphery of the rod.
- the cable 11 is then cooled in a cooling tank 21.
- a cooling tank 21 As mentioned above, the layout very close to the extruder 20 and the cooling 21 is necessary to control the thickness of the sheath.
- the cable is then directed to a processing member prior 22, to prepare the sheath for deposition.
- This member 22 can be a heating member such as an oven or a flame, however, avoid heating the jacket to its melting point.
- the oven temperature is appropriately selected following the process.
- This member 22 can also perform a treatment by crown effect, that is to say that it subjects the sheath to a flow of ionized gas, air, for example.
- the cable 11 is introduced in a deposition chamber 23 to coat the sheath with a layer of material lubricant.
- This material has a very low coefficient of friction with respect to the internal surface of the pipe in which the cable must be engaged.
- the deposition chamber can take the form of a bath in which the material lubricant is suspended in solvents, from a calibrated supply chain also by the material in solution, or by a spraying machine which projects this material in emulsion.
- microbeads as taught in the second known solution cited in the introduction. These microbeads are made of material suitable, especially made of polytetrafluoroethylene. They can also be in inorganic material such as glass, quartz powder or ceramic. In this case, the deposition is carried out by spraying the microbeads which are in suspension in an emulsion or in a gas, for example compressed air, or well by means of a calibrated die.
- the above deposition chambers are however difficult to implement to control the amount or thickness of the material deposited.
- this chamber 23 takes the form a plasma phase spray chamber. It is possible to deposit microspheres in plasma phase with a suitable assembly which can be derived from the plasma technique used for the manufacture of fibers (preforms).
- this technique itself causes an increase in the sheath temperature, it may happen that an independent reheating device does not is not necessary, the deposition chamber 23 ensuring the heating functions and deposit.
- an evaporation device 24 at the outlet of the deposition chamber 23 to evaporate the solvents which served as vehicle with lubricating material.
- This evaporation organ will generally take the shaped like an oven.
