Definitions

  • the coolant is led back to the nozzle via a water feed channel and away from the nozzle via a water return channel.
  • These channels are usually offset by 180 ° to each other and the coolant should flow around the nozzle as evenly as possible on the way from the flow to the return. Nevertheless, overheating in the vicinity of the nozzle channel are repeatedly found.
  • substantially cylindrical is intended to mean that the outer surface is, at least when thinking away of the grooves, such as liquid inlet and - Weglaufnuten, by and large cylindrical.
  • substantially conically tapered means that the outer surface at least at Thinking away the grooves, like liquid inlet and return grooves, is tapered conically on the whole.
  • the bores for the cooling liquid inlet to the Küh gutkeits Weglauf can be arranged offset by 180 °.
  • the width of the liquid return groove and in case b) the width of the liquid inlet groove in the direction of contact in the range of 90 ° to 270 °.
  • the groove in the circumferential direction of the first portion of the nozzle over an angle of 60 ° to 300 ° and in case b) the groove in the circumferential direction of the first portion of the nozzle over an angle in the range of 60 ° to 300 °.
  • the width of the liquid return groove and in case b) the width of the liquid inlet groove in the circumferential direction is in the range of 120 ° to 270 °.
  • the in the FIG. 1 shown plasma burner head 1 takes with an electrode holder 6, an electrode 7 in the present case via a thread (not shown).
  • the electrode is designed as a flat electrode.
  • air or oxygen can be used as the plasma gas (PG).
  • a nozzle 4 is received by a substantially cylindrical nozzle holder 5.
  • a nozzle cap 2 which is attached via a thread (not shown) to the plasma burner head 1, fixed the nozzle 4 and forms with this a cooling liquid space 10.
  • the cooling liquid space 10 is sealed by a realized with a circular ring 4.16 seal, which is located in a groove 4.15 of the nozzle 4, between the nozzle 4 and the nozzle cap 2.
  • the nozzle bore 4.10 of the nozzle 4 is insufficiently cooled because the cooling liquid insufficiently flows through the part 10.20 of the cooling liquid space 10 closest to the nozzle bore and / or even on the side facing the coolant liquid return not reached.
  • Fig. 7a is a sectional view taken along the line AA of the plasma torch FIG. 7 showing how the space 10.11 formed by the coolant inlet groove 4.20 of the nozzle 4 and the nozzle cap 2 through the sections 4.41 and 4.42 of the protruding areas 4.31 and 4.32 of the nozzle 4 in combination with the inside surface of the nozzle cap 2 shunts between the coolant flow and the coolant return prevent.
  • FIG. 7b is a sectional view taken along the line BB of the plasma burner head FIG. 7 showing the plane of the deflection spaces 10.10.
  • the center of thedeckenkeitszulaufnut 4.20 and the center of thedeckensschreiblaufnut 4.22 are offset by 180 ° to each other over the circumference of the nozzle 4 and the same size. Between thedeckenkeitsvorlaufnut 4.20 and thedeckensschreiblaufnut 4.22 are the outwardly projecting areas 4.31 and 4.32 with the corresponding sections 4.41 and 4.42.
  • FIG. 9 shows a plasma burner head according to another specific embodiment of the invention.
  • the nozzle 4 has twodestattkeitsvorlaufnuten 4.20 and 4.21.
  • the cooling liquid is almost perpendicular to the longitudinal axis of the plasma burner head 1 of the nozzle holder 5 on the nozzle 4 aptly in the Coolant space 10 passed.
  • the cooling liquid is deflected from the direction parallel to the longitudinal axis in the bore of the cooling liquid flow WV of the plasma torch in the direction of the first nozzle section 4.1 almost perpendicular to the longitudinal axis of the plasma burner head 1.
  • the cooling liquid flows through a groove 5.1 of the nozzle holder 5 in the two formed by thedeckenkeitszulaufnuten 4.20 and 4.21 of the nozzle 4 and the nozzle cap 2 spaces 10.11 and 10.12 to the nozzle bore 4.10 surrounding area 10.20 of the cooling liquid space 10 and flows around the nozzle 4 there , Thereafter, the cooling liquid flows back through the space formed by thedestattkeitsschreiblaufnut 4.22 of the nozzle 4 and the nozzle cap 2 10.15 back to the coolant return WR, the transition here is almost perpendicular to the longitudinal axis of the plasma burner head, by a deflection 10.10.
  • Fig. 9a is a sectional view taken along the line AA of the plasma torch FIG. 9 showing how the spaces 10.11 and 10.12 formed by the cooling liquid inlet grooves 4.20 and 4.21 of the nozzle 4 and the nozzle cap 2 pass through the sections 4.41 and 4.42 of the protruding areas 4.31 and 4.32 of the nozzle 4 in combination with the inner surface of the nozzle cap 2 Prevent the coolant flow and coolant return. At the same time, a shunt between the spaces 10.11 and 10.12 is prevented by the section 4.43 of the protruding area 4.33.
  • the cooling liquid flows through the groove 4.6, which extends in the circumferential direction of the first section 4.1 of the nozzle 4 on a partial circumference between the grooves 4.20 and 4.21, ie over about 300 °, in the two by thedeckenkeitsvorlaufnuten 4.20 and 4.21 of the Nozzle 4 and the nozzle cap 2 formed spaces 10.11 and 10.12 to the nozzle bore 4.10 surrounding area 10.20 of the cooling liquid space 10 and flows around the nozzle 4 there. Thereafter, the cooling liquid flows back through the space 10.15 formed by the cooling liquid return groove 4.22 of the nozzle 4 and the nozzle cap 2 to the coolant return WR, the transition taking place substantially parallel to the longitudinal axis of the plasma burner head.
  • Fig. 11a is a sectional view taken along the line AA of the plasma torch FIG. 11 showing how the spaces 10.11 and 10.12 formed by the cooling liquid inlet grooves 4.20 and 4.21 of the nozzle 4 and the nozzle cap 2 form a shunt through the sections 4.41 and 4.42 of the protruding areas 4.31 and 4.32 of the nozzle 4 in combination with the inside surface 2.5 of the nozzle cap 2 between the coolant flow and coolant return. At the same time, a shunt between the spaces 10.11 and 10.12 is prevented by the section 4.43 of the protruding area 4.33.
  • Thedeckenkeitszulaufnuten 4.20; 4.21 and thedeckenkeitsschreiblaufnut 4.22 are the outwardly projecting areas 4.31; 4.32 and 4.33 with the corresponding sections 4.41; 4.42 and 4.43.
  • Thedeckenkeitszulaufnuten 4.20 and 4.21 are by a circumferential direction of the first section 4.1 of the nozzle 4 on a Partial circumference between the grooves 4.20 and 4.21, ie over about 300 ° extending groove 4.6 of the nozzle connected together. This is particularly advantageous for the cooling of the transition between the nozzle holder 5 and the nozzle 4.
  • FIGS. 15 and 16 shown nozzle caps according to further particular embodiments of the invention differ from the in Fig. 14 shown embodiment in the shape of the recesses 2.6.
  • the recesses 2.6 in Fig. 15 are in the view shown there to the nozzle tip out frustoconical, with in Fig. 16 the frustoconical shape is slightly rounded.
