Definitions

  • the invention relates to a screw compressor system of the type which conventionally has a screw compressor block, a pressure control valve, optionally with an air filter apparatus, an oil separation tank, an oil circulation system with an oil temperature controller, an oil filter and connections for a cooler, a fine separator with an oil return apparatus and a pressure maintaining valve in a clean air outlet.
  • a screw compressor system of the initially mentioned type is known, for example, from German Patent DE 100 33 154 C2.
  • the purpose of the invention is to develop a screw compressor system of the aforementioned type such that it will achieve a construction that is as compact as possible with flexibility that is as great as possible with respect to the manner of design of the screw compressor system. Also, the construction principle in accordance with the invention can be used in screw compressor systems with a different construction.
  • a screw compressor system which comprises the initially named functional parts is made available which is characterized in that it is designed as a modular construction to be compact and flexible such that the screw compressor block, the oil separation tank, the oil supply duct for the oil temperature controller and the air intake duct are combined in a base housing with a lid and/or that the fine separator, the oil return, the minimum pressure-maintaining valve with the clean air outlet, the oil temperature controller, the oil filter and the connections for the cooler are combined in a multifunction block.
  • a base housing can be used into which corresponding functional parts of the screw compressor system are integrated, and furthermore, a multifunction block which can be variably used in a flexible manner and into which other functionally important parts of the screw compressor system are integrated can be used.
  • the screw compressor system in accordance with the invention thus, in the manner of a modular system, comprises two base components, specifically a base housing with a lid and/or a multifunction block. In this way, the screw compressor system in accordance with the invention can be adapted to the respectively desired requirements and demands. In this case, there are common base components in the modular system, as a result of which a construction which is more favorable to production with reduced production costs can be implemented.
  • FIG. 1 is a perspective exploded view of a screw compressor system in accordance with the invention
  • FIG. 2 is a perspective view of the screw compressor system shown in FIG. 1 in the assembled state
  • FIG. 3 is a perspective partially exploded view of the above embodiment of a screw compressor system viewed in a direction looking at the operator side and the drive side of the system,
  • FIG. 4 is a perspective view of the screw compressor system as shown in FIG. 3 in the mounted assembly position.
  • FIGS. 1 and 2 show an overall screw compressor system 1 in accordance with the invention with only the functionally important parts of this screw compressor system being shown.
  • the construction principle of the invention in a modular construction can be recognized from the figures of the drawings.
  • the illustrated screw compressor system 1 comprises a base housing 2 as the base module whose interior can be closed with a lid 3 .
  • a screw compressor block as the base module in the combined arrangement, a screw compressor block, an oil separation tank, an oil supply duct for the oil temperature controller and the air intake duct are integrated.
  • An intake valve 5 with an intake filter 6 mounted on it is shown schematically in FIG. 1 in an exploded view.
  • the intake valve 5 with the intake filter 6 is mounted on the base housing part 2 as shown in FIG. 2 .
  • FIG. 1 shows a multifunction block 10 .
  • this multifunction block 10 a fine separator, an oil return, a minimum pressure-maintaining valve with a clear air outlet, an oil temperature controller, an oil filter and optional connections for a cooler are combined.
  • This multifunction block 10 can be adapted to the demands and requirements to be satisfied with respect to the filter apparatus and the like.
  • a schematically indicated control unit 11 is dynamically connected to the multifunction block 10 .
  • FIG. 1 shows that this screw compressor system 1 is designed to be compact and can be flexibly adapted with respect to requirements.
  • FIGS. 3 and 4 show details with respect to a drive side 15 and an operator side 16 .
  • the multifunction block 10 is located on the operator side 16 of the screw compressor system 1 and is therefore easily accessible for necessary maintenance work without other functional parts of the screw compressor system 1 having to be dismounted.
  • the drive side 15 lies somewhat at a right angle to the operator side 16 on which the multifunction block 10 is located and attached. Thus, there is unhindered access to the drive side 15 of the screw compressor system 1 .
  • a screw compressor system 1 as a module component in the manner of a modular system, on the one hand, are assigned to a base housing 2 as the base module, and on the other hand, to a multifunction block 10 as a further functional component in order to enable a compact and flexible design of the screw compressor system in accordance with the invention.
