Definitions

  • the present invention relates to a modular system of modular centrifuges, in particular for the lubricating oil of an internal combustion engine, with a modular system modular.
  • Centrifuges of the type mentioned are long in use and generally known due to their widespread use, even in a use for the lubricating oil of an internal combustion engine.
  • centrifuges are used to deposit entrained in the lubricating oil of the engine fine dirt particles from the lubricating oil. It is usual that the centrifuge is arranged in a side stream of the lubricating oil circuit of the internal combustion engine, while in the main stream of the lubricating oil circuit a lubricating oil filter with a replaceable filter cartridge is common.
  • the rotor reaches due to its size and its correspondingly large mass, despite a high lubricating oil used for its drive only relatively low speeds, which is the soil removal detrimental.
  • a disadvantage is also to be mentioned that many different centrifuges must be manufactured and kept in adaptation to different sized internal combustion engines, which makes the production, storage and distribution of the centrifuges and their spare parts maintenance consuming and expensive.
  • a proposed solution to reduce spare parts inventory is, for example, from the document US-A-4400167 known.
  • a centrifuge is disclosed in which different rotor types can be used in the housing interior formed by a centrifuge base and a centrifuge lid. An adaptation of this centrifuge to different requirements is still consuming.
  • the object is to provide centrifuges of the type mentioned, which avoid the disadvantages set out and in which in particular a cheaper and easier production with variable adaptability to different requirements, easier storage and spare parts and an efficient and effective operation are reachable.
  • the solution to this problem is achieved according to the invention each with a modular system of modular centrifuges as defined by the claim 1 or claim 4 or claim 5 or claim 6.
  • the modular system according to the invention of modular centrifuges a simpler and, in particular, considerably more economical production of different centrifuges is advantageously made possible, it being possible for different parts of the modular system to be combined and assembled in different combinations with different centrifuges.
  • the spare parts maintenance and supply is simplified in this way and thus more economical.
  • the different rotors expediently have volumes which differ in suitable stages, in order to be able to adapt the capacity of the centrifuge to suit different sized internal combustion engines. It can be covered with relatively few different sizes of rotors a sufficiently large range of centrifuge sizes and performance for practice.
  • a first solution according to the invention provides that the modular system comprises various pedestals, which differ in the number of rotors that can be connected thereto.
  • a Sokkel can carry two, three or more rotors, the rotors can be removed from the modular system.
  • the rotors can be identical or different from each other, whereby a good adaptation of the centrifuge to different needs is possible.
  • a further embodiment proposes that with the various sockets one of the number of rotors corresponding to the number of one of the rotors associated, uniform or different high Dekkeln is connectable.
  • each rotor is assigned its own cover.
  • Each lid can be adapted to the associated rotor in height, of course, here again the possibility exists to mutually identical rotors and the same lid or alternatively different high rotors and matched, different heights cover with the common base to connect.
  • a second solution of the invention provides that the modular system comprises a uniform base, different height lid and different high rotors.
  • the base remains the same, while to achieve different powers of the centrifuge only different height lid and different high rotors are used.
  • the production of the most complex component performing socket is particularly economical because a single base for different sized centrifuges can be used.
  • the base can be produced in larger quantities, which reduces the cost per piece.
  • a further embodiment of the invention provides that the modular system comprises various pedestals, which differ by the height of a cooperating with the lid peripheral wall, a uniform cover or different high cover and different high rotors.
  • the different height of the peripheral wall for the production of different sized centrifuges is also used.
  • the base remains unchanged in all other parts except its peripheral wall, which although different sockets must be made, but these differ only in the height of their peripheral wall. This still allows an economical production, because, for example, in casting production of the base large parts of a mold can be used for different base; for different peripheral wall heights, for example, exchangeable mold parts can be used in the mold.
  • the modular system comprises various sockets, namely a first, as a master socket with an associated device, in particular internal combustion engine, connectable Base and at least a second, as slave socket connectable to the first socket base.
  • This aspect of the invention provides to produce a centrifuge as needed with one or more rotors, each rotor being associated with a separate pedestal.
  • the centrifuge consists of the master socket with an associated rotor and cover. If necessary, so in the requirement of a higher centrifuge performance, one or more slave sockets can be connected to the master socket, which in turn each carry a rotor and a lid.
  • the rotors or lids may be the same or different from each other.
  • a fourth solution of the invention provides that the modular system comprises a base, which is connected to one another with an associated device, in particular internal combustion engine, and on the other hand with other, identical sockets strung together.
  • this embodiment of the base is characterized in that a stringing together identical pedestal is possible.
  • a centrifuge with two or more sockets and a corresponding number of rotors and lids are modularly assembled to adapt the centrifuge to the particular need.
  • the centrifuge comprises a plurality of bases, it is also possible here to choose the rotors and lids equal or different from one another.
  • the invention provides that the base is a custom-made in adaptation to an associated device, in particular internal combustion engine component that can be assembled with different lids and / or with different rotors in different combinations to different centrifuges.
  • the base can be here, for example, a sand casting, which can be produced economically even with relatively small numbers. Rotors and covers from the modular program can then be connected with this individually manufactured base, so that no elaborate special designs are required for the rotors and lids.
  • the / each base for connection to an associated device, in particular internal combustion engine, and / or for connection to another socket has one or more simultaneous mechanical and fluid connection producing connecting flanges.
  • each centrifuge is a free-jet centrifuge, wherein the / each rotor has at least one recoil nozzle.
  • each rotor can be smaller within the modular system, there is the advantageous possibility that the / each rotor consists essentially or completely of plastic. This allows a cost-effective production, results in a low low weight of the rotors and ensures high speeds of rotation of the rotors in operation, which is very advantageous for the separation of dirt.
  • the various rotors of the modular system have a volume of 0.8 liters, 1.0 liters, 1.2 liters and 1.8 liters.
  • a volume range between 0.8 liter as a minimum when using only the smallest rotor and several liters when using several of the largest or largest rotors in the centrifuge cover, with a fine gradation in steps of down to 0.2 liters possible is.
