Japanese Unexamined Patent Publication No. 2013-144928

In the space-saving packaged fluid machine as described above, it is desirable to make it easy to take out the compressed part from the housing in order to maintain the compressed part.

On the other hand, the operation panel for operating the control circuit provided in the housing is arranged at a height that is easy for the user to operate or visually recognize. In addition, the operation panel is desired to have a structure that facilitates maintenance of the compression unit stored in the housing.

The packaged fluid machine in Patent Document 1 is effective when the operation panel itself is maintained. However, although the opening / closing part arranged on the operation panel is configured to be movable up and down, the width direction of the front surface is fixed, and even if the opening / closing part is moved downward to open, the compressed part is taken out from the housing. In that case, the opening / closing part becomes an obstacle.

That is, it is considered that the package type fluid machine in Patent Document 1 does not give sufficient consideration to facilitating the maintenance of the compression portion in the package type fluid machine.

An object of the present invention is to provide a packaged fluid machine in which the compressed portion can be easily taken out and maintained.

A preferred example of the present invention is a compressor unit having a compression unit for compressing a fluid, a housing in which the compressor unit is arranged, a front panel constituting the front surface of the housing, and an operation panel for receiving operations. And has a support shaft on the lateral end side of the operation panel, and has a support mechanism that can move the operation panel around the support shaft, and the compression portion can be taken out by the movement. It is a package type fluid machine.

According to the present invention, it is possible to provide a packaged fluid machine in which it is easy to take out the compressed portion and perform maintenance.

It is a front view of the package type fluid machine in Example 1. FIG. It is a figure which shows the internal structure seen from the front of the package type fluid machine in Example 1. FIG. It is a perspective view which shows the internal structure of the package type fluid machine in Example 1. FIG. It is a figure which shows the operation panel and the support mechanism in Example 1. FIG. It is a figure for demonstrating the compressor unit.

Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of the package type fluid machine 100 in the first embodiment. The front panel 12 constituting a part of the housing of the package type fluid machine 100 can be attached to and detached from the housing other than the front panel by using a holding mechanism such as a screw.

Further, an operation panel 11 for operating the package type fluid machine 100 is arranged in front of the package type fluid machine 100.

The front panel 12 is a panel that covers the front surface of the package type fluid machine 100 except for the position where the operation panel is arranged, and by removing the front panel 12, maintenance of internal parts and the like can be performed. By attaching and detaching the front panel 12, it is possible to widen the space for working in the lateral direction as compared with the case where the front panel 12 is a door type.

The operation panel 11 includes a power switch operated by the user and a display area for indicating an abnormality warning, and a cable for connecting to an inverter for controlling a motor or the like is arranged on the back side of the operation panel.

FIG. 2 shows a front view of the package type fluid machine 100 with the front panel removed.

The packaged fluid machine 100 of the first embodiment includes a three-stage compressor unit 2101, 2102, and 2103.

As shown in FIG. 5, each compressor unit 21 has a configuration including a compression unit 51, a motor 52, and a cooling fan 53.

In the first embodiment, as a compression method of the compression unit 51, a scroll compressor in which a compression chamber is formed between a fixed scroll and a swivel scroll and air is compressed by a swirl motion will be described as an example.

The compression unit 51 includes filters 22 at the top and bottom, and introduces air to be compressed from the filter 22. The air compressed by the compression unit 51 passes through a housing provided with a primary aftercooler, a secondary aftercooler, and a dryer for cooling the compressed air, and is supplied to an external air tank as compressed air.

FIG. 3 is a perspective view showing the internal configuration of the packaged fluid machine 100 according to the first embodiment.

A drawer mechanism 33 with a pedestal on which the compressor units 2101, 2102, and 2103 are mounted is provided. When performing maintenance, each compressor unit 2101, 2102, and 2103 can be pulled out or pushed into the front surface by using the pull-out mechanism 33. Here, the drawer mechanism 33 can be composed of a pedestal, rails, casters, and the like.

When pulling out the compressor unit 2101 on the uppermost stage, the operation panel 11 arranged in the front becomes an obstacle. Therefore, by rotating the package type fluid machine 100 to the front side by the support shaft of the support mechanism of the operation panel 11, even if the package type fluid machine 100 has a compact shape, the lateral direction of the package type fluid machine 100 is not lengthened. Maintenance of the compressor unit 2101, 2102, and 2103 can be facilitated.

The air that cools the primary aftercooler is blown from the cooling fan 53, cools the compression unit 51, and is exhausted from the exhaust duct 31. The exhaust duct 31 is arranged on the front side on the left side when viewed from the front of the machine room in which the compressor units 2101, 2102 and 2103 are arranged.

Inverter chambers 34 divided into three stages are arranged on the back side of the exhaust duct 31 corresponding to the compressor units 2101, 2102, and 2103, and each inverter chamber 34 has an inverter that controls the motor 52. Be placed.

Each compressor unit 2101, 2102, and 2103 arranges a compression unit 51, a motor 52, and a cooling fan 53 from the front side toward the back side. Since the compression unit 51, which is frequently maintained, is arranged on the front side, the maintenance work of the compression unit 51 can be facilitated.

FIG. 4 is a diagram showing an operation panel 11 taken out from the package type fluid machine 100 and a support mechanism 42 thereof.

FIG. 4A is a diagram showing the state of the operation panel 11 and the support mechanism 42 during normal operation, and FIG. 4B is a case where the compressor unit 2101, 2102, 2103 and the like are to be maintained. It is a figure which shows the state of the operation panel 11 and the support mechanism 42 in the above.

The support mechanism 42 is provided with a support shaft 41. The support shaft 41 is arranged on the right side of the short side of the rectangular operation panel 11 which is the end side of the package type fluid machine 100. By providing a hinge mechanism so that it can rotate around the support shaft 41, the operation panel 11 can be moved and held toward the end side in the lateral direction 43.

As shown in FIG. 4B, by moving the operation panel 11 substantially perpendicular to (including vertical) the front surface of the package type fluid machine 100, the uppermost compressor unit 2101 can be easily pulled out. Can be done. Further, when the secondary aftercooler and the dryer are arranged on the right side, the maintenance of the secondary aftercooler and the dryer should be performed at the same time as the maintenance of the compressor unit 2101, 2102 and 2103 having the compression unit and the motor. Can be done.

When maintaining the compressor unit 2101, the operation panel 11 may be moved by 90 degrees or more with respect to the front surface of the package type fluid machine 100 in order to facilitate the work.

FIG. 5 is a diagram for explaining the compressor unit 21. The compressor unit 21 has a configuration including a compression unit 51, a motor 52, and a cooling fan 53. In this embodiment, the compression unit 51 is a scroll compressor, and the motor 52 is an axial gap type motor.

In the compressor unit 21 of this embodiment, the motor 52 and the compression unit 51 are coupled to form a motor-integrated compressor unit. The motor 52 can be made thinner by using an axial gap type motor having a structure in which a rotor and a stator arranged in a disk shape rotate opposite to each other. Further, by using amorphous, which is a material having high magnetic permeability and low iron loss, as the stator core, it is possible to improve the efficiency of the motor 52 and further reduce the size.

A cooling fan 53 is installed on the end side of the rotating shaft 54 rotated by the motor 52. The cooling fan 53 has a structure in which rotary blades mounted on the rotary shaft 54 are housed in a resin fan cover.

The cooling fan 53 is a cooling fan that sucks in the outside air flowing from the side surface of the cooling fan by the rotation of the rotary blades driven by the rotating shaft 54 and generates cooling air.

The cooling air generated inside the fan cover due to the rotation of the rotary blade is supplied to the fixed scroll or the swivel scroll of the scroll compressor, which is the compression unit 51, through the cooling duct provided on the side surface of each compressor unit 21.

In this embodiment, when pulling out and maintaining each compressor unit 2101, 2102, 2103, the operation panel can be moved by the support mechanism so as not to be an obstacle when pulling out, so that each compressor unit 2101 can be moved. Maintenance of 2102 and 2103 can be facilitated.

Further, when performing maintenance of parts other than the compressor units 2101, 2102, and 2103 such as the aftercooler and the dryer, the operation panel can be moved so as not to be an obstacle, so that the maintenance can be facilitated.

The front panel 12 is not limited to one, and may be divided into a plurality of pieces. When the front panel 12 is divided into two upper and lower panels, the upper front panel 12 having an opening for the operation panel 11 has a shorter length in the vertical direction than the lower front panel 12. , The upper front panel 12 is divided so as to be lighter. This is because the upper front panel 12 is located at a height higher than the upper body of the worker, and a force is required when the front panel 12 is attached or detached.

The front panel 12 may be divided into two parts on the left and right sides. In that case, it is easier to work when the front panels are attached and detached when the widths of both front panels 12 are made equal.

A screw or a magnet is used as a holding mechanism for holding the front panel 12 in the housing of the package type fluid machine 100.

When the front panel 12 is divided into upper and lower parts, the upper front panel 12 may be held by a magnet in order to facilitate the maintenance of the operation panel 11. Further, the lower front panel 12 may be held by screws so that the multi-stage compressor units 2102 and 2103 do not accidentally pop out.

In the above embodiment, the operation panel 11 is arranged at the right end of the packaged fluid machine 100 when viewed from the front, but is arranged at the left end and the hinge is placed on the left side of the short side of the operation panel 11. May be placed in.

In the above embodiment, the compression unit 51 is a scroll compressor, and the motor 52 is an axial gap type motor using amorphous as a stator core. Not limited to these, the compression unit 51 may be a compressor other than the scroll compressor, for example, another compressor such as a reciprocating compressor. Further, as the motor, for example, a motor having another configuration such as a radial gap type motor can be used.
