Definitions

  • the present invention relates to a packaged compressor.
  • vibrations are generated by driving the compressor body, motors, fans, etc., so there are many technologies aimed at reducing vibrations.
  • Patent Document 1 is a prior art document in this technical field.
  • the screw compressor main body and the electric motor are arranged vertically and fixed to the same pedestal, the pedestal is placed on the base, and the weight of the screw compressor main body and the electric motor is the fixing portion between the base of the pedestal.
  • the structure supported by the legs of the gantry reduces the vibration generated by the compressor body.
  • Patent Document 1 describes a structure in which a leg that supports the gantry is added to the back side of the base in order to suppress the vibration generated by the compressor body, but the vibration of the fan that cools the compressor body and the fan motor that drives the fan No consideration is given to suppression.
  • the present invention is, for example, a packaged compressor in which a compressor body, a fan, a fan motor for driving the fan, a fan mount on which the fan motor is mounted, and a base are housed in a package, and the fan mount.
  • the fan motor Is connected to the base via multiple legs, the fan motor has its axis of rotation installed horizontally with respect to the fan mount, and the outer circumference of the base is in contact with the ground, close to the ground side of the base. Configure the fan mount legs to be on the opposite side of the fan rotation direction.
  • vibration of the fan and the fan motor can be reduced.
  • FIG. 3 is a schematic configuration perspective view of the package type compressor according to the first embodiment. It is a perspective view which showed the positional relationship between a fan mount and a base in Example 1. FIG. It is a perspective view which showed the positional relationship between a fan mount and a base in Example 2. FIG. It is a perspective view which showed the positional relationship of a fan mount, a base, and a duct in Example 3. FIG. It is a perspective view which showed the positional relationship between a fan mount and a base in Example 4.

  • FIG. 1 is a schematic configuration perspective view of the air-cooled package type compressor in this embodiment.
  • package 1 contains each component.
  • the components include a compressor body 2, a motor 3, a suction filter 4, a fan 5, a fan motor 6, a fan mount 7, a base 8, a heat exchanger 9, an intake duct 10, an oil case 11 for storing circulating oil, and the like.
  • the compressor body 2 housed in the package 1 is driven by the motor 3 and is taken in from the suction filter 4 to compress the air.
  • the piping between the suction filter 4 and the compressor main body 2 is omitted.
  • the heat generated in the compressor is cooled in the heat exchanger 9 by the air taken in from the intake duct 10 using the fan 5.
  • the compressor main body 2, the fan 5 for cooling the compressor, the fan motor 6 for driving the fan 5, and the fan mount 7 on which the fan motor 6 is mounted are arranged on the base 8, and they are housed in the package 1. Has been done.
  • FIG. 2 is a diagram in which the fan 5, the fan motor 6, the fan mount 7, and the base 8 are omitted in the package type compressor shown in FIG.
  • the fan mount 7 has two legs 15 and is connected and arranged to the base 8 via the two legs 15.
  • the base 8 is formed by bending a sheet metal, and the bent portions at the four corners and the outer peripheral ends of the base 8 come into contact with the ground.
  • the fan motor 6 for driving the fan 5 is installed sideways with respect to the fan mount 7 so that the rotation axis is in the horizontal direction, and the fan 5 rotates around the rotation axis in the horizontal direction.
  • one of the two legs 15 of the fan mount 7 is configured to be close to the grounding side 14 of the outer peripheral end of the rigid base 8. In other words, vibration can be expected to be reduced by moving the leg opposite to the rotation direction of the fan toward the base ground side.
  • connection portion of the leg 15 of the fan mount 7 with the base 8 is close to the outer peripheral side of the base 8.
  • the number of fan mount legs is not limited to two, and may be multiple.
  • the vibration of the fan and the fan motor can be reduced.
  • FIG. 3 is a diagram in which the fan 5, the fan motor 6, the fan mount 7, and the base 8 are omitted in the package type compressor in this embodiment.
  • the same components as those in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted.
  • the difference from FIG. 2 is that the two legs 15 of the fan mount 7 have a V shape. In other words, the area on the base 8 connected and surrounded by the two legs 15 is larger than the area of the mounting surface on which the fan motor 6 of the fan mount 7 is mounted.
  • FIG. 4 is a diagram in which the fan 5, the fan motor 6, the fan mount 7, and the base 8 are omitted in the package type compressor in this embodiment.
  • the same components as those in FIG. 3 are designated by the same reference numerals, and the description thereof will be omitted.
  • the difference from FIG. 3 is that a duct 16 is provided around the fan 5 for the purpose of rectifying the cooling air.
  • the pressure loss can be reduced and the air volume increases by rectifying the cooling air in the duct 16, so that the heat exchanger 9 shown in FIG. 1 can be effectively cooled.
  • FIG. 5 is a diagram in which the fan 5, the fan motor 6, the fan mount 7, and the base 8 are omitted in the package type compressor in this embodiment.
  • the same components as those in FIG. 3 are designated by the same reference numerals, and the description thereof will be omitted.
  • the reinforcing member 17 is provided on the base 8. That is, in FIG. 3, only the bent portions at the four corners and the outer peripheral end of the base 8 are in contact with the ground, and the other portions are not in contact with the ground. However, in FIG. 5, the reinforcing member 17 is provided. It is also installed in places.
  • one of the two legs 15 of the fan mount 7 is configured to be close to the place where the reinforcing member 17 is provided.
  • the fan motor is more effective. Vibration can be suppressed.
  • connection portion of the leg 15 of the fan mount 7 with the base 8 should be close to the portion where the reinforcing member 17 is provided.
