Definitions

  • the invention relates to a screw compressor according to the preamble of claim 1. Such screw compressors are known.
  • the object of the invention is to perfect the compact design of the screw compressor according to the preamble of claim 1 and in particular to make it suitable for larger outputs. This object is achieved by the means specified in the characterizing part of patent claim 1.
  • the previously customary design, in which the compressor block was used axially parallel to the cylindrical pressure vessel from the front side of the pressure vessel, is considerably improved:
  • the front side of the compressor block is no longer seated on a relatively large cylindrical pressure vessel final special flange, and the cylindrical pressure vessel no longer requires a dome-like attachment, which was previously required to accommodate an oil separator cartridge.
  • the compressor block can now be inserted into the pressure vessel from above and then directly attached to an inner flange of a relatively small flange opening, which corresponds approximately to the size of the end face of the compressor block, with its drive end face.
  • the inner flange can be present directly at the flange opening of the pressure vessel.
  • an intermediate flange can also be used which is inserted into the flange opening from the outside and which then has the inner flange carrying the compressor block. Due to the transverse position of the compressor block, practically the entire cover area and the space above the compressor block in the pressure vessel are gained, so that several oil separating cartridges can now be provided in a battery-like parallel arrangement, which is particularly useful for larger outputs.
  • These oil separating cartridges are combined in a simple manner by means of a base of a conventional pressure-maintaining and non-return valve which is placed on the cover and which has corresponding connecting channels. They are easily accessible for maintenance without other components of the compressor having to be dismantled.
  • the compressor block is arranged in such a way that the rotors lie one above the other and that fresh air can be supplied laterally directly from the cylinder wall.
  • the suction regulator placed on a pipe socket of the pressure vessel is provided with a tubular extension which extends into the interior of the pressure vessel and is pushed onto a corresponding counterpart on the compressor block, which contains the air supply duct, with the interposition of an O-ring seal.
  • the screw compressor essentially consists of a cylindrical pressure vessel 1, which serves as an oil separator and oil reservoir, a compressor block 2 arranged therein, two oil separator cartridges 3 with minimum pressure and non-return valves (4, a suction regulator 5 and a drive motor to be coupled to the shaft 6 of the compressor block, which is not shown in detail
  • the cylindrical pressure vessel 1 is vertical and is filled with oil up to level 7.
  • the compressor block 2 is arranged transversely to the axis of the pressure vessel 1. It is inserted into the pressure vessel 1 from above during assembly of the compressor and screwed with its drive end side 12 to the intermediate flange 14 carrying the inner flange 13.
  • the intermediate flange 14 is placed from the outside on a nozzle-like flange 15 of the pressure vessel. With the intermediate flange 14 together a support frame 16 for the drive motor is attached to the pressure vessel. There If the two rotors 17, 18 of the compressor block 2 are arranged one above the other, the fresh air can be supplied laterally from the cylinder wall of the pressure vessel 1 without special pipelines.
  • the pressure vessel 1 has a pipe socket 19 with a flange 20, and the suction regulator 5 is placed on this flange 20.
  • the intake regulator containing the usual items such as filter 21, throttle 22, relief valve 23, solenoid valve 24 and actuating cylinder 25 has a tubular extension 26 which extends into the pressure vessel 1.
  • the suction regulator 5 is pushed onto a counterpart 27 located on the compressor block 2 with the interposition of an O-ring seal 28.
  • the counterpart 27 seated on the compressor block 2 contains a check valve 29 and, moreover, serves to supply fresh air to the compressor block 2, which is indicated by the channel 30.
  • the air compressed by the rotors 17, 18 exits the compressor block via the manifold 31 and enters the pressure vessel 1. It passes through the oil separator cartridges 3 and is fed via the minimum pressure and non-return valve 4 to the actual compressed air reservoir or the consumer, which is not shown in detail, however.
