Definitions

  • the invention relates to a pump, in particular a fuel pump, with at least one working space in which a piston limits the working space in a cylinder by means of a drive system and pressurizes a fluid, in particular fuel, present in the working space.
  • the patent has DE102007038529A1 a high-pressure fuel pump with at least one working space to the subject, in which fuel is subjected to high pressure.
  • the high-pressure fuel pump is drivingly coupled to a linear motor.
  • the patent DE102014202937A1 Further develops this approach and describes a pump having a pump cylinder head with a pump cylinder and a pump plunger translatable up and down in a cylinder guide recessed into the pump cylinder.
  • the pump tappet acts on the drive side with a linear drive.
  • the linear drive is mechanically connected to the pump tappet without backlash.
  • linear motors which can absorb high tightening forces.
  • a linear motor design is only profitable if used in a high volume product.
  • the linear motor can also be designed to exceed requested ratings. Pump-specific or oversized linear motors are generally very expensive.
  • the invention has for its object to provide a pump-specific, yet inexpensive drive for fuel pumps.
  • a pump in particular a fuel pump, with at least one working space in which a piston limits the working space in a cylinder by means of a drive system and pressurizes a fluid, in particular fuel, present in the working space, wherein the drive system comprises at least two linear motors includes.
  • Linear motors are preferably designed as direct drives and are therefore characterized by low noise emissions and high power density. They allow translational movements without gears, which is why they are considered to be low in wear and maintenance. An omission of the transmission also creates the prerequisite for a compact design.
  • the drive system of a pump, in particular of a fuel pump, according to the invention comprises at least two linear motors.
  • the linear motors are mainly identical and therefore suitable for series production. This also offers the advantage that linear motors kept as spare parts in stock and can be quickly replaced if necessary.
  • At least 20 electrically and / or mechanically parallel-connected linear motors drive the fuel pump.
  • a particularly safe and reliable operation which also allows a sufficient degree of scaling steps, is achieved with a drive system of 40 to 50 linear motors.
  • a drive system of 40 to 50 linear motors.
  • 128 or more linear motors can also form a drive system.
  • a drive system with a smaller number of linear motors is also possible.
  • a parallel connection of several linear motors also serves to increase the feed force.
  • the linear motors forming the drive system are preferably arranged in parallel on a support.
  • each linear motor has a mechanical power between 40 kW and 85 kW and provides a feed force of up to 20 kN.
  • the drive system preferably has at least one measuring system, at least one control unit for controlling the linear motors and at least one system for data transmission.
  • the measuring system preferably determines a position and / or speed of the linear motors on their respective travel path.
  • the position and / or speed can also be realized via a voltage observation in the linear motor, preferably encoderless.
  • the drive system has exactly one control unit.
  • the control unit controls the drive system.
  • the drive system which comprises at least two linear motors, acts here as just a linear motor.
  • the control unit issues commands to the drive system, in particular regarding the speed.
  • the control unit realizes the already mentioned scaling by controlling only a certain number of linear motors with less power requirement.
  • the data which includes, for example, information on position and speed, as well as the data containing commands to the linear motors are transmitted by means of a system for data transmission between the respective linear motor and the measuring system or the control unit. Also between the measuring system and the control unit is advantageously carried out a system for data transmission. For data transmission, various bus systems or Industrial Ethernet can be used.
  • the invention and a related elimination of expensive and maintenance-intensive mechanical transmission components such as gear and / or cam and / or crankshaft mechanical conversion is greatly simplified.
  • an assembly and handling are facilitated because fewer and smaller parts must be connected.
  • Linear motors can be kept as spare parts in stock.
  • the pump can continue to be driven - albeit at a reduced power - since the other linear motors are not affected by the error that has occurred.
  • the faulty one Linear motor can be exchanged quickly and easily, which has a positive effect on high machine availability.
  • the invention offers the possibility, by obstructing a larger number of linear motors than required, of realizing a redundancy in the drive system of linear motors by inserting at least one redundant linear motor into the drive system according to the invention.
  • Suitable for the invention are both linear motors with moving magnets, so-called moving magnet linear motors, and linear motors with moving coil, so-called moving coil linear motors.
  • linear motors with a moving magnet are preferably used, since in this case electrical supply lines for the linear motor do not have to be moved. This offers the advantage that a travel path on which the linear motor moves, can be designed in any length.
  • each linear drive motor forming the drive system is assigned at least one converter, in particular exactly one converter, which couples the respective linear motor to an electrical power supply network. This allows, inter alia, a simple and quick replacement of the linear motor in case of failure.
  • a piston rod connected to the piston concentrates a force, in particular a feed force, which the linear motors apply.
  • the invention has the advantage that by means of the drive system, the required high forces can be accomplished by a piston rod, the forces of several parallelrither, small and series-compatible linear motors bundles.
  • the figure shows a drive system 3 of five linear motors 1a, 1b, 1c, 1d and 1e, which can travel back and forth on a respective travel path 2a, 2b, 2c, 2d and 2e in order to drive a pump 4, in particular a fuel pump.
  • the linear motors are arranged in parallel and mechanically connected such that by means of a piston rod 7, the forces of the linear motors 1a to 1e are bundled.
  • Each linear motor 1a to 1e is respectively coupled to an inverter 30a, 30b, 30c, 30d, and 30e to an electric power grid 40.
  • the linear motors 1a to 1e are connected via electrical power supply lines 31a, 31b, 31c, 31d and 31e to the respective associated converters 30a to 30e.
  • the converters 30a to 30e are connected to the electrical energy supply network 40 via further electrical energy supply lines 32a, 32b, 32c, 32d and 32e.
  • the force of the linear motors 1a to 1e is bundled by means of a piston rod 7.
  • the individual linear motors 1a to 1e move at the same speed.
  • the piston rod 7 moves in this way a piston 6, which limits a working space 5 in a cylinder of a pump 4.
  • the working space 5 befindettess fluid, in particular fuel such as oil or gas, is thereby pressurized.
  • fuel is drawn into the working space 5 through an inlet valve 11, which is preferably controlled by the control unit 21 via a data transmission system 25, by the drive system 3 comprising linear motors 1a to 1e - and thus each individual linear motor 1a to 1e 1e - receives the command from the control unit 21 to drive to a rear, the pump 4 facing away from the end of the respective travel path 2a to 2e.
  • the working space 5 acquires its maximum size, and a resulting negative pressure in the working space 5 draws in the fuel via the inlet valve 11.
  • a measuring system 20 detects when each linear motor 1a to 1e has reached an end position, whereupon the control unit 21 stops the linear motors 1a to 1e.
  • the measuring system 20 is connected via a system for data transmission 26 with the linear motors 1a to 1e.
  • the measuring system 20 advantageously also detects a speed and position of each linear motor 1a to 1e and can transmit this data to the control unit 21 via a system for data transmission between the control unit and the measuring system 27.
  • the control unit 21 therefore has the possibility of reacting by, for example, decelerating or accelerating the linear motors 1a to 1e.
  • control unit 21 When the end position of the linear motors 1 a to 1 e is reached, the control unit 21 preferably closes both the inlet valve 11 and the outlet valve 10. For this purpose, an optional system for data transmission between the control unit 21 and the valves 29 is available.
  • the drive system 3 of linear motors 1a to 1e is caused by the control unit 21 to move in the direction of a front, the pump-facing end of the respective travel path 2a to 2e.
  • the fuel located in the working space 5 is pressurized. If the pressure is high enough, the control unit 21 opens the outlet valve 10.
  • a level of the pressure is detected by means of the measuring system 20 via an optional system for data transmission between the measuring system and valves 28.
  • the control unit 21 and the measuring system 20 may have separate arithmetic units or a common arithmetic unit.
  • the data transmission systems 25, 26, 27, 28 and 29 may be connected by wires or wirelessly.
  • the drive system 3 of linear motors shown by way of example in the figure has only five linear motors 1a to 1e. According to the invention, however, depending on the field of application, a larger or smaller number of linear motors can form a drive system of linear motors.
