Definitions

  • the invention relates to a vibrating piston pump, in particular a vibrating piston vacuum pump, a method for operating a pump of this type and a method for producing a pump family of this type.
  • Vibrating piston pumps are known from DE 41 02 710 AI. They have a piston that moves back and forth in a cylinder. The piston is driven by a linear or oscillating piston drive, which has electromagnetic means comprising the piston.
  • pumps of this type are used as vacuum pumps, they can be dry with a suitable choice of material for the piston skirt and for the cylinder, i.e. lubricant-free, operated. This advantage is already used in piston vacuum pumps in which a crankshaft drive is provided as the drive for the pistons.
  • vacuum pumps With vacuum pumps, it is generally customary to manufacture a pump that works according to a specific pump principle in several sizes - delivery volume, single, multi-stage and offer to meet customer needs for pumps with different final pressures and / or pumping speeds.
  • the development and manufacture of such pump families is complex.
  • the present invention has for its object to provide a vibrating piston pump, in particular vibrating piston vacuum pump, in which the described, relatively high development and manufacturing costs for the assembly of a pump family with a wide pumping speed range and / or with different final pressures is no longer necessary.
  • this object is achieved in that this pump, in particular a vacuum pump, consists of several structurally identical modules of a vibrating piston pump which, depending on the customer's requirements, are connected in parallel and / or in series and each have a vibrating piston drive.
  • modules connected in parallel e.g. T. modules connected in series
  • z. T. parallel e.g. T. modules connected in series
  • pump families can be created with members who have different final pressure behavior and / or different pumping speeds.
  • the module itself is a member of the family. It has the highest final pressure and the lowest pumping speed. Further advantages and details of the invention will be explained on the basis of exemplary embodiments schematically illustrated in FIGS. 1 to 10. Show it
  • FIGS. 1 to 4 views of different embodiments of pumps according to the invention
  • Figures 8 to 10 are schematic representations of possible variants.
  • FIGS. 1 to 4 are designated by 1, their oscillating piston pump modules by 2.
  • the modules are fastened to a rail 3 (FIGS. 1, 2, 4) or to two rails 4, 5, which on the one hand have a supporting function and on the other are equipped with ducts which act as a common inlet duct, as a common outlet duct, as intermediate ducts or also can be used as channels for receiving electrical lines.
  • FIGS. 1 and 2 show views of an embodiment with three modules 2. They are fastened one above the other on a rail 3 which is arranged vertically and is equipped with a foot 6 which extends below the modules 2.
  • the inlet and outlet of the modules 2 each open into one of their two end faces. With this end face they are attached to the rail 3.
  • the rail 3 is equipped with longitudinally extending channels. One of them forms an inlet channel with which all inlets of the modules 2 are connected in a sealing manner. A second one forms an outlet channel which is connected to all the outlets of the modules.
  • the inlet duct and outlet duct are closed.
  • the connector 7 assigned to the inlet channel forms the inlet 9, the connector 8 assigned to the outlet channel forms the outlet 10 of the pump 1 according to the invention.
  • the design of the pump 1 according to FIGS. 1 and 2 is equipped with three modules 2. Their pumping speed corresponds to the sum of the pumping speeds of the identical individual modules. When producing pumps 1 of this type with a different pumping speed, the number of modules 2 can be varied accordingly.
  • Figure 3 shows an embodiment in which the modules 2 are attached to two rails 4, 5. They are supported by a common foot 6.
  • the first rail 4 can accommodate the inlet duct and the second rail 5 can accommodate the outlet duct.
  • Rail 5 contains the outlet channel with the connecting piece 8, which forms the outlet 10.
  • the two modules 2 are provided with a high-vacuum pump 12 (for example, a friction vacuum pump, such as turbomolecular, molecular, compound pump) upstream.
  • a high-vacuum pump 12 for example, a friction vacuum pump, such as turbomolecular, molecular, compound pump
  • This is attached to the rail 4.
  • Your outlet is connected to the inlet channel in the rail 4.
  • the inlet channel is closed on both end faces of the rail 4.
  • the inlet connection 13 of the high vacuum pump 12 forms the inlet 9 of the pump system according to FIG. 3.
  • FIG. 3 shows, by way of example, that a supply, control and / or display device 14 common to several or all pumps 2, 12 can be attached to one of the rails 4, 5.
  • the necessary lines can be routed through channels in the rails 4, 5.
  • a device 14 of the type described common to all pumps can also be present in pumps 1 according to FIGS. 1, 2 or 4 with only one rail 3 and can be fastened to this rail 3.
  • a control device 14 common to the modules 2 allows pumps 1 equipped with an even number of modules 2 to be operated in a vibration-free manner. According to the invention, this is done in that the pistons of the modules 2 are operated in pairs with an identical frequency and with an opposite direction of movement.
  • FIG. 4 also shows an embodiment with two oscillating piston pump modules 2 and a high vacuum pump 12.
  • the difference from FIG. 3 is that only one rail 3 is provided, in which the common inlet duct and the common outlet duct are located. The inlet duct is closed on both sides. The inlet connection of the high-vacuum pump 12 forms the inlet 9 of the pump 1. The outlet channel opens into the gene outlet 8, which forms the outlet 10 of the pump 1.
