Definitions

  • the invention relates to a reciprocating compressor with flow control, arranged with a at least one automatic suction valve of the compressor Abhebegreifer that holds at least one sealing element of the suction valve over a portion of the working cycle of the compressor by means of an electrically operated lift-off, as well as a method for flow control Such a reciprocating compressor.
  • off EP 694 693 A1 a toiletströmregelung known for reciprocating compressors, in which a hydraulic control cylinder, via a control member periodically in the stroke cycle with pressure medium can be acted upon and relieved, acting in the stroke direction on the closing member of the open-to-hold suction valve.
  • the hydraulic lifting force is thus abruptly reduced at a certain piston angle, whereby a safe and rapid closing of the suction valve is initiated.
  • Out EP 1 400 692 A1 Similar flow rate controls are also known with pneumatic actuation, which has the advantage that the operating pressure can be derived directly from the reciprocating compressor itself. Due to the relatively high compressibility of the compressed gas, however, it is necessary to comply with precisely defined conditions for the volumes and venting times to be vented.
  • the object of the invention is to design a reciprocating compressor with electrically operated reminding matter so that the known arrangements of the type described in terms of reducing size and power consumption can be improved, while still provided similar to the described hydraulic remindströmregelungen high actuation forces at high momentum dynamics can be.
  • the lifting device has an electric motor drive whose output element has a direction of rotation inclined guide rail for low-friction rolling elements, on the other hand with an inclined counter-guide on a rotationally secured Abhebeelement interact, which communicates with the lift-off gripper.
  • a relatively small-sized electric motor can be used, the rotational movement of the inclined pair of rolling easily and with high actuation force and high dynamics of movement in the required, acting on the lift-off grip holding force or movement can be implemented.
  • the electric motor is formed in a preferred further embodiment of the invention as a brushless DC motor with surface-mounted bandaged permanent magnet, which allows high dynamics with a small size.
  • Particularly preferred in this context is to form the electric motor with a hollow shaft rotor, in which the nut of the ball screw drive is integrated, which minimizes the inertia of the rotor or the rotary drive as a whole.
  • the hollow shaft rotor has a diameter in the range of 30-50 mm, the pitch of the ball screw drive preferably being in the range of 6-12 mm. This results in particularly well-adapted conditions for high actuation forces at the same time high dynamics of the lift-off.
  • the elements of the Wälzparungen at least partially made of ceramic.
  • the extremely high acceleration and braking torques of the electromotive drive which occur under certain circumstances can lead to the rolling elements not being able to follow the movement of their guide track immediately, which would lead to slippage on the bearing tracks and thus to wear.
  • This problem can be solved by using ceramic bearings or hybrid bearings with ceramic rolling elements and appropriate preload.
  • additional spring elements can be provided, which, with appropriate coordination, makes it possible to relieve the electromotive drive.
  • circuit elements for regenerative braking and for the intermediate storage and reuse of the electrical energy recovered therefrom may preferably be in capacitors, where the generated and stored current may be used either for the next actuation operation on the same valve or else on another suction valve of the compressor.
  • the current lifting force is adapted to the course of the sudströmkraft. While the suction valve is kept open, the level of the backflow force depends on the actual piston speed, which is known or ascertainable, for example, via a crank angle sensor. The motor current for generating the necessary hold-open force can then be adjusted accordingly.
  • Fig. 1 shows a section through the region of a suction valve of a reciprocating compressor according to the invention with flow control
  • Fig. 2 an alternative embodiment of an electrically operated lifting device for a reciprocating compressor according to the invention with flow control in partial and schematic section
  • Fig. 3 a detail of another alternative embodiment of the drive of a lifting device for such a compressor.
  • the lifting device 3 has for this purpose as drive to an electric motor 5, the output element 6 (here designed as a central shaft) has a direction of rotation inclined guideway 7 (here circumferential spiral groove) for low-friction rolling elements 8, on the other hand with an inclined counter-guide. 9 cooperate on a rotationally secured Abhebeelement 10, which is in communication with the Abhebegreifer 2.
  • the electric motor 5 which is preferably designed as a brushless DC motor with surface-mounted bandaged permanent magnets 12, has a hollow-shaft rotor 13 as an output element 6, in which the nut 14 of the recirculating-ball spindle drive is integrated.
  • the hollow shaft rotor 13 preferably has a diameter in the range of approximately 30-50 mm, wherein the pitch of the ball screw drive formed by nut 14, rolling elements 8 and rotationally secured lifting element 10 is preferably in the range of 6 to 12 mm.
  • the hollow shaft rotor 13 is mounted on the stator housing 15 via bearings 16.
  • the cooperating with the bandaged permanent magnet 12 stator is denoted by 17.
  • Fig. 3 forms the output member 6 of the electric motor 5 together with the rotation secured Abhebeelement 10 and the rolling elements 8 arranged therebetween a limited angular rotation permitting inclined ramp drive, which for example also allows the use of cylindrical, truncated cone or barrel-shaped rolling elements 8, which can transmit greater axial forces ,
  • the elements 6, 7, 8, 9, 10 of the Wälzparungen the Kugelumlaufspindel- or Schrägstrang drive can at least partially made of ceramic, which together with a corresponding bias of the drives slipping of the rolling elements 8 in highly dynamic operations with the associated risk of damage prevents the rolling element guides.
  • additional spring elements 18 may be provided, as they are here in FIG Fig. 1 are indicated only schematically.
  • circuit elements 20 may be provided for regenerative braking and for the intermediate storage and reuse of the electrical energy recovered therefrom, which avoids unnecessary heating or the need for additional cooling of the lifting device. Furthermore, could be provided in the control device 19 and other circuit elements 21 for adjusting the hold-open force of the lifting device 3 to the respective acting montströmkraft by controlling the energization of the electric motor 5, which also helps to reduce unnecessary heat loss.
