Definitions

  • This invention relates to a cooling device for a compressor, and more particularly, to a system for cooling a rotor of a oscillation type air compressor.
  • the primary object of the present invention is to provide a cooling system for cooling the rotor of an oscillation type compressor.
  • Another object of the present invention is to provide a rotor cooling system for an oscillation type compressor in which the rotor is cooled to such a temperature that the abrasion of the sealing material is prevented.
  • Still another object of the present invention is to provide a rotor cooling system for an oscillation type compressor in which the compressed air in the cylinder is also cooled by contacting the surface of the rotor and the temperature of the discharged air is, accordingly lowered.
  • the rotor in the compressor is provided with an axial hole extending axially through the center thereof for introducing cooling fluid thereinto.
  • FIG. 1 is a transverse cross-sectional view of the compressor in accordance with the present invention.
  • FIG. 2 is a longitudinal sectional view taken along the line lI-Il in FIG. 1.
  • a rotor 3 having vanes 3a and 3b is rotatably supported in the bore of a cylinder l.
  • the rotor 3 is provided at the radial ends of vanes 3a and 3b with sealing material 2 such as carbon or tetra fluoro ethylene in sliding 'contact with the inner surface bore of the cylinder l.
  • a pair of inlet valve seats 7 are fixed to the cylinder 1 on opposite sides of the rotor 3.
  • a pair of sealing material pieces 5 are disposed on the valve seats 7 in contact with the outer peripheral surface of the rotor 3.
  • Air is introduced into the cylinder 1 through inlet passages 4 and inlet valves 6. Compressed air is discharged out of the cylinder through discharge valves 8 and discharge valve boxes 9.
  • the cylinder l has a water cooling jacket construction so as to be maintained at comparatively lower temperatures.
  • one end (the right end in the embodiment shown in the drawings) of the rotor 3 is extended outward from the bearing 11 in the axial direction and is provided with an axial hole or bore 19 along the longitudinal axis thereof extending from said one end.
  • a housing 20 encloses the extended portion of the rotor 3, and has a cooling liquid injection pipe 24 extending coaxially with and into the hole 19. Also, a cooling liquid discharging pipe 26 is provided on the housing 20.
  • a bearing l0 is disposed on the opposite end of said extended portion of the rotor 3, with the rotor also being extended leftward.
  • a pin 12 and an arm 13 are provided for interconnecting the rotor with a driving means.
  • Sealing cylinders or sleeves 14 and 15 for partitions 16 and 17 are provided at the opposite ends of the rotor 3.
  • An inlet duct 18 is connected with said inlet passages 4, and a pair of seal rings 21 are interposed between the extended end portion of the rotor 3 and the housing 20 with a slight space therebetween as illustrated in FIG. 2.
  • the peripheral wall of the housing 20 is provided with a drain hole 22 for precluding cooling liquid from entering the bearing l1.
  • This drain hole 22 is provided for the purpose of precluding the cooling liquid from entering into the bearing 1l around the left seal ring 2l even if there is leakage into the space between the rings 21 over the right seal ring 21.
  • An external cooling liquid supply tube 25 is connected with said cooling liquid injection pipe 24 outside the housing 20.
  • a cooling medium is supplied into the injection pipe 24 from the external supply tube 25 and the cooling medium or liquid is introduced into the axial hole 19 at the left end thereof and flows rightward in the hole 19 cooling the central portion of the rotor 3 and is discharged out of the housing 20 through the discharge pipe 26.
  • the rotor 3 is positively cooled by a cooling means, and accordingly, the temperature of the rotor is not increased as much as in the conventional cornpressor even if the discharge pressure is increased.
  • the compressed air having accordingly an increased temperature is also cooled by contact with the surface of the rotor 3 reduction and lowering of the temperature of the discharged air is achieved.
  • said rotor being bored axially from said one end
  • cooling agent injection pipe fixed to said housing and extending within said rotor bore and forming with said rotor bore an annular coolant flow passage opening into said chamber
  • a cooling agent discharge pipe connected to said housing and open to said chamber
  • cooling of said rotor in the vicinity of said peripheral contact with said carbon sealing member reduces the average abrasion rate of said carbon sealing member about eight fold.
