本考案は、ポンプ製品の可動翼操作機構に適用されるシール装置に関する。 The present invention relates to a sealing device applied to a movable blade operating mechanism of a pump product.
【0002】0002
従来、ポンプ製品において、可動翼操作機構が設置されるランナボス内は、封 入された潤滑油によって該機構部の潤滑が行われてきた。しかしながら、ランナ ボス内の潤滑油を完全にシールすることは不可能で、最近は、環境悪化等防止の ため、該ランナボス内の潤滑を清水にて行う方法が実施されつつある。 Conventionally, in pump products, the inside of the runner boss where the movable vane operating mechanism is installed is sealed. The mechanical parts have been lubricated by the lubricating oil contained therein. However, the runner It is impossible to completely seal the lubricating oil inside the boss, and recently, efforts have been made to prevent environmental deterioration. Therefore, a method of lubricating the inside of the runner boss with fresh water is being implemented.
【0003】 また、翼操作に必要な操作力はランナボスから離れた場所に設置されるバルコ ン、油圧ピストン等により発生させているので、当然該装置とランナボス内の操 作機構とを連結する操作棒が必要となる。0003 In addition, the operating force required to operate the wings is controlled by a balcoon located far from the runner boss. Since it is generated by a runner, hydraulic piston, etc., it is natural that the device and the operation inside the runner boss are connected. An operating rod is required to connect the operating mechanism.

そこで、上述した潤滑油又は清水がこの操作棒を通じて漏洩しないよう、従来 にあっては、Oリング、Vリング等の高分子材料で作製したシールを使用してい る。しかしながら、該シールを使用した場合、該シールとの摺動摩擦による軸摩 耗が発生するという問題があった。 Therefore, in order to prevent the above-mentioned lubricating oil or clean water from leaking through this operating rod, In some cases, seals made of polymeric materials such as O-rings and V-rings are used. Ru. However, when using this seal, shaft friction due to sliding friction with the seal There was a problem of wear and tear.
【0005】 本考案は、このような従来技術の課題を解決するためになされたもので、軸摩 耗の発生を確実に防止できるようにした可動翼操作機構のシール装置を提供する ことを目的とする。[0005] This invention was devised to solve the problems of the conventional technology. To provide a sealing device for a movable wing operating mechanism that can reliably prevent wear and tear. The purpose is to

上記の課題を解決するために、本考案は、ランナボス内の封入液体が外部へ漏 洩しないよう、操作棒と主軸との間にシール部材を配設した可動翼操作機構のシ ール装置において、該シール部材を軸方向に柔軟性を有する部材により作製する と共に、該シール部材から漏洩した液体を検知する検知手段を設けたものである 。 In order to solve the above problems, the present invention has been developed to prevent the liquid sealed inside the runner boss from leaking to the outside. The system of the movable wing operating mechanism has a sealing member between the operating rod and the main shaft to prevent leakage. In the sealing device, the sealing member is made of a member that is flexible in the axial direction. In addition, a detection means for detecting liquid leaking from the seal member is provided. .

上記の手段によれば、操作棒と主軸との間に設けられるシール部材として、軸 方向に柔軟性を有する部材、例えば高圧、高速条件下のメカニカルシールに採用 されている溶接ベローズ等の部材を使用している。したがって、主軸とシール部 材との間の摺動摩擦をなくすことができ、軸摩耗の発生を防止できる。 According to the above means, the shaft is used as a sealing member provided between the operating rod and the main shaft. Used for directionally flexible members, such as mechanical seals under high pressure and high speed conditions. We use parts such as welded bellows, which are Therefore, the main shaft and seal part It is possible to eliminate the sliding friction between the shaft and the material, and prevent the occurrence of shaft wear.

以下、図1を参照して本考案の一実施例について詳細に説明する。図1は、本 実施例に係る可動翼操作機構のシール装置を示す断面図である。 Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG. Figure 1 shows the book It is a sectional view showing a sealing device of a movable wing operation mechanism concerning an example.
【0009】 図1において、主軸1の内部には操作棒2が配設されており、該操作棒2の先 端側には、主軸1と共に回転運動しながら直線運動をするロッド3が嵌装されて いる。[0009] In FIG. 1, an operating rod 2 is disposed inside a main shaft 1, and the tip of the operating rod 2 is A rod 3 that moves linearly while rotating together with the main shaft 1 is fitted on the end side. There is.
【0010】 可動翼ポンプでは、バルコン、油圧ピストン等で発生させた翼開閉操作力を駆 動装置4を介して操作棒2に伝え、さらにガイドロッド5に沿った操作棒2の直 線運転をリンク機構6によりベーン7の回転運動に変換するよう構成されている 。0010 In movable vane pumps, the driving force is the blade opening/closing force generated by a balcon, hydraulic piston, etc. It is transmitted to the operating rod 2 via the moving device 4, and furthermore, it is transmitted directly to the operating rod 2 along the guide rod 5. It is configured to convert linear operation into rotational movement of the vane 7 by a link mechanism 6. .
【0011】 そして、この可動翼操作機構の潤滑剤(例えば水)はランナボス8内に封入さ れており、前記駆動装置4側の液体(例えば油)との混合を避けるため、シール 部材9が操作棒2と主軸1との間に装着配置された構造となっている。[0011] The lubricant (for example, water) for this movable blade operating mechanism is sealed in the runner boss 8. In order to avoid mixing with the liquid (e.g. oil) on the drive device 4 side, a seal is installed. The structure is such that a member 9 is installed between the operating rod 2 and the main shaft 1.
【0012】 ロッド3は、上述したように、主軸1と共に回転運動しながら、直線運動する ため、シール部材9は該直線方向の動きに追随できる、つまり軸方向に柔軟性を 有するベローズ等の部材により作製されている。0012 As described above, the rod 3 moves linearly while rotating together with the main shaft 1. Therefore, the sealing member 9 can follow the movement in the linear direction, that is, it has flexibility in the axial direction. It is made of members such as bellows that have a
【0013】 また、シール部材9が万一破損した際、ランナボス8内の封入液が、操作棒2 と主軸1との間の隙間を伝わるが、該封入液の駆動装置4側への漏洩を防止する ために、操作棒2の周囲に補助シール部材10を嵌着させた構造としている。[0013] In addition, in the event that the seal member 9 is damaged, the sealed liquid in the runner boss 8 will be removed from the operating rod 2. The liquid is transmitted through the gap between the main shaft 1 and the main shaft 1, but this prevents the sealed liquid from leaking to the drive device 4 side. Therefore, the structure is such that an auxiliary seal member 10 is fitted around the operating rod 2.
【0014】 さらに、主軸1において、該補助シール部材10の手前側にはドレン穴11が 穿設されていると共に、該ドレン穴11に連通するドレン受け12が主軸1の外 周側に配設されており、該ドレン受け12にて通常点検時に漏洩の有無を検知で きる構造としている。そして、該ドレン受け12には漏洩検知器13が取り付け られており、自動漏洩検知器が可能となっている。[0014] Furthermore, in the main shaft 1, a drain hole 11 is provided on the front side of the auxiliary seal member 10. A drain receiver 12 which is bored and communicates with the drain hole 11 is located outside the main shaft 1. It is arranged on the peripheral side, and the presence or absence of leakage can be detected at the drain receiver 12 during normal inspection. It has a structure that allows A leak detector 13 is attached to the drain receiver 12. It is possible to install an automatic leak detector.

以上述べたように、本考案によれば、可動翼操作機構のシール装置において、 操作棒と主軸との間に配設したシール部材を軸方向に柔軟性を有する部材により 作製したことにより、主軸とシール部材との間の摺動摩擦を排除でき、これによ って軸摩耗の発生を確実に防止できるという優れた効果を奏する。また、検知手 段を設けた構成としたことにより、前記シール部材より漏洩が起こったとしても 、該漏洩した液体を容易に検知できるという効果も奏する。 As described above, according to the present invention, in the sealing device of the movable wing operating mechanism, The sealing member placed between the operating rod and the main shaft is made of a member that is flexible in the axial direction. By creating this, it is possible to eliminate sliding friction between the main shaft and the sealing member, which results in This has the excellent effect of reliably preventing the occurrence of shaft wear. In addition, the detection hand Due to the stepped structure, even if leakage occurs from the sealing member, This also has the effect that the leaked liquid can be easily detected.
