Definitions

  • the present invention relates to a package-type fluidic apparatus in which a fluid machine such as a scroll compressor, a vacuum pump, an expander or a blower is connected to a drive source.
  • a fluid machine such as a scroll compressor, a vacuum pump, an expander or a blower is connected to a drive source.
  • a single high-output compressor is included within the package, or a plurality of low-output compressors are piled up to form a high-output compressor in a package.
  • a plurality of compressors such as four are piled up to constitute a single package compressor. When it operates with about 100 % of compression air, all the four compressors operate.
  • One of the four stops with about 70 % of air consumption; two stop with less than 50 %; three stop with further decrease; and all stop with further decrease.
  • electric power consumption is corresponding to the compression air consumption.
  • Electric power consumption decreases compared with a single high-output compressor. If the compressor stops owing to any cause, capability for producing compression air becomes null immediately in the single high-output compressor to result in stop of all machines in which compression air is used, thereby increasing damage in the factory.
  • a plurality of compressors even if one stops, it will avoid the risk that operation completely stops, as the others continue to operate.
  • a plurality of compressors may preferably be employed.
  • a compressor and its drive source form a set of subsidiary unit.
  • a required area increases to unable its location.
  • a plurality of subsidiary units are vertically piled.
  • Two housings 2,2 each of which has four chambers 1 piled up are disposed with a space which is a sucking path 3.
  • the housings 2,2 have the same shape and size, and the four chambers 1 have the same shape and size.
  • the sucking path 3 is closed by a removable inspection door 5 between front walls 4,4 over the housings 2,2.
  • the upper part of the sucking path 3 is closed by an operation-display plate 5b.
  • the rear end of the sucking path 3 opens, and external air is taken in through the rear opening.
  • the side ends of the operation-display plate 5b are mounted with screws to the opposing ends of the housings 2,2, and the operation-display plate 5b can be removed, if required.
  • the inspection door 5 is removable by pushing down a slide latch 5a with a finger to open, so that sucking filters of fluid machines 8 in the housings 2,2 are inspected for maintenance.
  • a motor 7 and the fluid machine 8 such as a compressor or a decompression device behind the motor 7 are connected to pulleys 9,10 and a belt 11 to form a fluid machine unit 12.
  • a sucking hole 14 is formed through the inner side wall 13 to allow each of the housings 2,2 to communicate with the sucking path 3.
  • an exhaust hole 16 is formed in a rear wall 15.
  • a tall exhaust duct 17 is provided along the four exhaust holes 16 vertically arranged behind the housing 2.
  • An electric exhaust fan 18 is provided in the top wall of the exhaust duct 17.
  • the motor 7 and fluid machine 8 in the chamber 1 are cooled with external air, thereby avoiding overheat generated with continuous long-time operation and preventing damage to sliding parts.
  • the motor 7 and fluid machine 8 in the chamber 1 can be inspected and maintained by removing a closing plate at the rear end of the sucking path 3 and then removing the inner side wall 13 facing the sucking path.
