Description

本発明は、パッケージ内に、圧縮機本体と、これを駆動するモータと、圧縮機本体で圧縮された空気を一時的に貯留する貯留用タンクとを格納してなるパッケージ型空気圧縮装置に関する。   The present invention relates to a package-type air compressor in which a compressor main body, a motor that drives the compressor, and a storage tank that temporarily stores air compressed by the compressor main body are stored in a package.

空気圧縮装置は、モータ音以外に、圧縮機本体における駆動部が運転時に発生する音、さらに圧縮空気の脈動等による振動、および貯留用タンクとの共鳴音等により相当の騒音が発生する。そのため、これらの騒音が問題となる場合には、圧縮機本体等をパッケージ内に格納したパッケージ型空気圧縮装置が用いられている。   In the air compressor, in addition to the motor sound, considerable noise is generated by sound generated by the drive unit in the compressor body during operation, vibration due to pulsation of compressed air, resonance sound with the storage tank, and the like. Therefore, when these noises become a problem, a package type air compressor in which a compressor body and the like are stored in a package is used.

しかし、空気圧縮装置は、熱を発生するため、外部からパッケージ内に冷却用気体を導入し、パッケージ内を冷却する必要がある。この冷却には、一般にパッケージ内に外気を取り入れ、パッケージ内を循環させた後に、排気用ファンによって、外部に排気している。   However, since the air compressor generates heat, it is necessary to introduce a cooling gas into the package from the outside to cool the package. For this cooling, outside air is generally taken into the package, circulated through the package, and then exhausted to the outside by an exhaust fan.

しかし、従来、パッケージ内における外気の循環が必ずしも円滑に行われておらず、そのため、冷却効果が充分とは言えないという問題があった。   However, conventionally, the circulation of the outside air in the package is not always performed smoothly, and thus there is a problem that the cooling effect is not sufficient.

パッケージ型空気圧縮装置における改良技術として、騒音を減少する技術が、たとえば特許文献１により提案されている。   As an improved technique in the package type air compressor, a technique for reducing noise has been proposed by, for example, Patent Document 1.

しかし、この特許文献１においては、パッケージ内における冷却用気体の循環の向上については、全く考慮されていない。
特公平５−７５９１８号公報 However, in this Patent Document 1, no consideration is given to the improvement of the circulation of the cooling gas in the package.
Japanese Patent Publication No. 5-75918

本発明は、上記の現状に鑑み、パッケージ内における冷却用気体の循環の向上を図り、パッケージ内の冷却効果を向上させることを目的としている。   In view of the above-described present situation, the present invention aims to improve the circulation of the cooling gas in the package and improve the cooling effect in the package.

本発明によると、上記課題は、特許請求の範囲における各請求項に記載するように、次のようにして解決される。   According to the present invention, the above-described problem is solved as follows, as described in each of the claims.

(１) パッケージ内に、圧縮機本体と、これを駆動するモータと、圧縮機本体で圧縮された空気を一時的に貯留する貯留用タンクとを格納してなり、パッケージの外部から冷却用気体を導入して、パッケージ内を循環させた後に排気するようにしたパッケージ型空気圧縮装置において、圧縮機本体とモータとを、パッケージ内に設けた支持台上に載置するとともに、貯留用タンクを、その底部をパッケージ内の床面から離間させた状態で、前記支持台における天板の下方に位置させて、貯留用タンクの外周面と、支持台における天板および脚板との間に、間隙をもたせて、支持台に吊支する。 (1) A compressor main body, a motor for driving the compressor, and a storage tank for temporarily storing air compressed by the compressor main body are stored in the package. In the package-type air compressor that circulates in the package and then exhausts, the compressor body and the motor are placed on a support base provided in the package, and the storage tank is In a state where the bottom portion is separated from the floor surface in the package , the gap is placed between the outer peripheral surface of the storage tank and the top plate and the leg plate of the support table, and is positioned below the top plate of the support table. Suspend it on the support base.

(２) 上記(１)項において、支持台の天板に垂設するか、または支持台の両脚板間に懸架して設けた吊支部材に、貯留用タンクを吊支する。 (2) In the above item (1) , the storage tank is suspended from a suspension member that is suspended from the top plate of the support base or suspended between both leg plates of the support base.

(３) 上記(１)項または(２)項において、貯留用タンクにおけるフランジ部をもって、貯留用タンクを吊支する。 (3) In the above item (1) or (2) , the storage tank is suspended by the flange portion of the storage tank.

(４) 上記(３)項において、貯留用タンクのフランジ部を、吊支部材にボルト締めすることにより、貯留用タンクを吊支部材に吊支する。 (4) In the above item (3) , the storage tank is suspended from the suspension member by bolting the flange portion of the storage tank to the suspension member.

(５) 上記(１)項〜(４)項のいずれかにおいて、支持台の脚板または天板の少なくとも一方に、冷却用気体を貫流させる貫流孔を設ける。 (5) In any one of the above items (1) to (4) , a flow-through hole through which the cooling gas flows is provided in at least one of the leg plate or the top plate of the support base.

請求項１記載の発明によれば、貯留用タンクが、その底部をパッケージ内の底面から離間させた状態で、上方から吊支されているため、従来、貯留用タンクを支持するために、貯留用タンクの下方に設けられていた幅広の脚板を必要としない。そのため、貯留用タンクの下方における冷却用気体の循環が、脚板によって阻害されることがなく、優れて良好となる。   According to the first aspect of the present invention, since the storage tank is suspended from above with the bottom portion thereof being separated from the bottom surface in the package, the storage tank has been conventionally used to support the storage tank. There is no need for a wide leg plate provided below the tank. Therefore, the circulation of the cooling gas below the storage tank is not hindered by the leg plate and is excellent.

本発明者の研究によれば、従来、貯留用タンクの下方における冷却用気体の循環不良が、パッケージにおける冷却用気体の全体の循環不良の大きな原因となっていたことが判明した。   According to the inventor's research, it has been found that the poor circulation of the cooling gas below the storage tank has been a major cause of the poor circulation of the cooling gas in the package.

本発明においては、貯留用タンクの下方における冷却用気体の循環が優れて良好となるため、パッケージ内の冷却効果が格段に向上する。   In the present invention, since the cooling gas circulation under the storage tank is excellent and good, the cooling effect in the package is remarkably improved.

また従来、貯留用タンクから圧縮空気を供給する場合、通常、アフタークーラを経由して供給していたが、本発明においては、パッケージ内の冷却効果が向上するため、貯留用タンク内の圧縮空気も、従来に比較して効果的に冷却される。このため冷却能力の小さいアフタークーラをも使用可能となり、装置全体のコストを低減することができる。   Conventionally, when compressed air is supplied from a storage tank, it is normally supplied via an after cooler. However, in the present invention, the cooling effect in the package is improved, so the compressed air in the storage tank is improved. Also, it is cooled more effectively than in the past. For this reason, an aftercooler with a small cooling capacity can be used, and the cost of the entire apparatus can be reduced.

また、貯留用タンクを吊支するための特別の装置を別途設ける必要がなく、従来、圧縮機本体とモータとを載置していた支持台を、そのまま利用して、簡単に貯留用タンクを吊支することができる。 In addition, there is no need to provide a special device for suspending the storage tank , and the storage tank can be simply installed by using the support base on which the compressor main body and the motor have been placed. Can be suspended.

さらに、貯留用タンクの下方のみならず、貯留用タンクと、支持台における天板および脚板との間にも間隙をもたせてあるため、貯留用タンクの外周面全体における冷却用気体の循環が、一層良好となる。 Furthermore, since there is a gap not only below the storage tank but also between the storage tank and the top plate and the leg plate in the support base, the circulation of the cooling gas in the entire outer peripheral surface of the storage tank is Even better.

請求項２記載の発明によれば、貯留用タンクの外周面と、支持台における天板及び脚板との間に、間隙をもたせて、貯留用タンクを支持台に容易に吊支することができる。 According to the second aspect of the present invention, the storage tank can be easily suspended from the support table by providing a gap between the outer peripheral surface of the storage tank and the top plate and the leg plate of the support table. .

請求項３記載の発明によれば、貯留用タンクに別途、特別の吊支部を設けることなく、貯留用タンクに一般に設けられているフランジ部を利用して、貯留用タンクを容易に吊支することができる。 According to the third aspect of the present invention, the storage tank is easily suspended by using the flange portion generally provided in the storage tank without separately providing a special suspension support portion in the storage tank. be able to.

請求項４記載の発明によれば、吊支部材とボルトをもって、貯留用タンクを簡単に吊支することができる。 According to the fourth aspect of the present invention, the storage tank can be easily suspended with the suspension member and the bolt.

請求項５記載の発明によれば、冷却用気体の循環が、支持台の脚板や天板によって阻害されることはなく、一層良好な循環が得られる。 According to the invention described in claim 5, the circulation of the cooling gas is not hindered by the leg plate or the top plate of the support base, and a better circulation is obtained.

請求項６記載の発明によれば、貫流孔における、冷却用気体の通過断面積を大きくすることができるとともに、容易に貫流孔を設けることができる。 According to the sixth aspect of the present invention, the passage cross-sectional area of the cooling gas in the through hole can be increased, and the through hole can be easily provided.

請求項７記載の発明によれば、冷却用気体が案内板によって案内され、冷却用気体を、貯留用タンクの冷却に、効率よく利用することができる。 According to the seventh aspect of the present invention, the cooling gas is guided by the guide plate, and the cooling gas can be efficiently used for cooling the storage tank.

請求項８記載の発明によれば、支持台がフレーム構造であるため、板状体で構成される場合に比較して、冷却用気体の循環が容易となる。 According to the eighth aspect of the invention, since the support base has a frame structure, the cooling gas can be easily circulated as compared with the case where the support base is configured by a plate-like body.
