Description

本発明は、発電所に設備する制御用空気圧縮機に係り、特に劣化した潤滑油を取り出す機構を有する制御用空気圧縮機及びその潤滑油の処理方法に関する。   The present invention relates to a control air compressor installed in a power plant, and more particularly to a control air compressor having a mechanism for extracting deteriorated lubricating oil and a method for treating the lubricating oil.

発電所における制御用空気圧縮機は、圧油タンク補給用、発電機ブレーキ用に用いられる。例えば、揚水式発電所では、揚水始動時の吸出し管水面の押下げ用として短時間に多量の空気を消費するので、大容量の空気タンク、空気圧縮機が設置されている。このような空気圧縮機の容量は、最低常用油圧からポンプ水車全台について各１回の水面押下げを行った後、空気タンクの圧力を最低常用圧力に６０〜１２０分で回復できる容量のものを設置する。揚水機による調相運転は、吸出し管水面を押し下げた状態で実施するため、これを補給する空気量が必要となる。   A control air compressor in a power plant is used for replenishing a pressure oil tank and for a generator brake. For example, in a pumped storage power plant, a large amount of air tank and air compressor are installed because a large amount of air is consumed in a short time for pushing down the suction pipe water surface at the time of pumping start. The capacity of such an air compressor is such that the pressure of the air tank can be restored to the minimum normal pressure in 60 to 120 minutes after pressing the water surface once for all pump turbines from the minimum normal hydraulic pressure. Is installed. Since the phase adjustment operation by the pump is carried out with the suction pipe water surface pushed down, an amount of air to replenish this is required.

このような空気圧縮機に関する技術として、例えば特許文献１の特開平１１−１３６２２号公報「多気筒空気圧縮機」に示すように、クランク角度の位相をずらせて気筒を取り付けてある多気筒空気圧縮機において、各気筒の吐出口を相互に連通して相互の吐出管の有効利用を図ることができる多気筒空気圧縮機が提案されている。
特開平１１−１３６２２号公報 As a technique relating to such an air compressor, for example, as shown in Japanese Patent Application Laid-Open No. 11-13622 “Multi-cylinder air compressor” of Patent Document 1, a multi-cylinder air compression in which cylinders are mounted with the crank angle shifted in phase is provided. In the machine, a multi-cylinder air compressor has been proposed in which the discharge ports of the respective cylinders are communicated with each other to effectively use the discharge pipes.
Japanese Patent Laid-Open No. 11-13622

図４に示すような多気筒空気圧縮機５１は、各気筒部５２には、クランク室５３からの劣化した潤滑油が溜まり、この潤滑油を廃油処理する必要がある。廃油処理する場合は、図５に示すように、気筒グランドカバーであるアクリル板５４を外して，人間の手による清掃や廃油の処理していた。例えば、気筒部５２のアクリル板５４を取り外し、注射器状の器具を使って廃油を吸い出していた。この作業は、１台の多気筒空気圧縮機５１当たり年に２〜３回程度で実施していた。   In the multi-cylinder air compressor 51 as shown in FIG. 4, deteriorated lubricating oil from the crank chamber 53 is accumulated in each cylinder portion 52, and it is necessary to perform waste oil treatment on this lubricating oil. In the case of waste oil treatment, as shown in FIG. 5, the acrylic plate 54, which is a cylinder ground cover, is removed, and cleaning or waste oil treatment is performed by human hands. For example, the acrylic plate 54 of the cylinder part 52 is removed, and the waste oil is sucked out using a syringe-like instrument. This operation was performed about 2 to 3 times per year per one multi-cylinder air compressor 51.

従来の廃油抜き取り作業は、多気筒空気圧縮機５１の運転中に、ピストンスピンドル部５５といった可動部の近くに手を入れ、注射器状の器具を使い廃油の油溜まりを手作業で処理している大変危険な作業であった。そこで、この廃油抜き取り作業に際して、多気筒空気圧縮機５１を停止しなければならないという問題を有していた。また、取り外したアクリル板５４を落として破損するというおそれもあった。   In the conventional waste oil draining operation, during operation of the multi-cylinder air compressor 51, a hand is placed near a movable portion such as the piston spindle portion 55, and a waste oil sump is manually processed using a syringe-like instrument. It was very dangerous work. Therefore, there has been a problem that the multi-cylinder air compressor 51 has to be stopped during this waste oil draining operation. There is also a risk that the removed acrylic plate 54 may be dropped and damaged.

本発明は、かかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、気筒部に配管を設けることで、可動部の近くに人の手を近づけないので安全に作業を行え、この空気圧縮機を停止することなく気筒部から廃油を排出することができる制御用空気圧縮機及びその潤滑油の処理方法を提供することにある。   The present invention has been developed to solve such problems. In other words, the object of the present invention is to provide piping in the cylinder part so that a human hand cannot be brought close to the movable part so that the work can be performed safely, and waste oil is discharged from the cylinder part without stopping the air compressor. Another object of the present invention is to provide a control air compressor that can be used and a method for treating the lubricating oil.

本発明の空気圧縮機によれば、発電所における圧油タンク補給、発電機ブレーキ等に用いられる圧縮空気を供給する、複数の気筒部（３）を設けた制御用空気圧縮機（１）であって、各気筒部（３）の油溜り部（５）に、廃油ドレン排出用の排出口（６）を開け、各排出口（６）に、ドレン弁（８）を具備した配管（７）を取り付け、前記配管（７）の吐出口（９）に油回収器（１０）を備えた、ことを特徴とする制御用空気圧縮機が提供される。   According to the air compressor of the present invention, a control air compressor (1) provided with a plurality of cylinder parts (3) for supplying compressed air used for replenishment of a pressure oil tank at a power plant, generator brakes, etc. Then, a discharge port (6) for discharging waste oil drain is opened in the oil reservoir (5) of each cylinder portion (3), and a pipe (7 having a drain valve (8) in each discharge port (6) (7) ), And an oil recovery device (10) is provided at the discharge port (9) of the pipe (7).

前記油溜り部（５）内において、排出口（６）の間に補強用リブ（１１）が形成されているときは、該排出口（６）から廃油が流出しやすいように該補強用リブ（１１）に油通過孔（１２）を開けることが好ましい。
垂直に配置されている気筒部（３）の油溜り部（５）には、排出口（６）を２箇所設け、各排出口（６）それぞれに配管（７）を取り付け、かつ１本に集約した配管（７）の下流にドレン弁（８）を取り付けることが好ましい。 When the reinforcing rib (11) is formed between the discharge ports (6) in the oil reservoir (5), the reinforcing ribs are provided so that the waste oil can easily flow out from the discharge ports (6). It is preferable to open an oil passage hole (12) in (11).
Two oil outlets (6) are provided in the oil reservoir (5) of the vertically arranged cylinder part (3), and pipes (7) are attached to each of the outlets (6). It is preferable to attach a drain valve (8) downstream of the aggregated pipe (7).

本発明の処理方法によれば、発電所における圧油タンク補給、発電機ブレーキ等に用いられる圧縮空気を供給する、複数の気筒部（３）を設けた制御用空気圧縮機（１）から廃油を抜き取る潤滑油の処理方法であって、各気筒部（３）の油溜り部（５）に開けた排出口（６）から、該排出口（６）に取り付けた配管（７）のドレン弁（８）を操作することにより、前記制御用空気圧縮機（１）を運転しながら前記配管（７）を経由して廃油を排出する、ことを特徴とする制御用空気圧縮機における潤滑油の処理方法が提供される。   According to the treatment method of the present invention, waste oil is supplied from a control air compressor (1) provided with a plurality of cylinder parts (3) for supplying compressed air used for replenishment of a pressure oil tank at a power plant, generator brakes, and the like. The drain valve of the pipe (7) attached to the discharge port (6) from the discharge port (6) opened in the oil reservoir (5) of each cylinder portion (3) By operating (8), waste oil is discharged via the pipe (7) while operating the control air compressor (1), and the lubricating oil in the control air compressor is characterized in that A processing method is provided.

上記構成の発明では、気筒部（３）の油溜り部（５）に、ドレン弁（８）を具備した配管（７）を取り付けているので、このドレン弁（８）を開閉するだけで廃油ドレン排出用排出口（６）から廃油を容易に取り出すことができる。従来のようにアクリル板（１０）を外して、可動部の近くに手を入れる作業がなく安全に作業を行うことができる。従来のようにアクリル板（１０）の破損も防止することができる．
特に、パトロール時に油溜り部（５）に溜まった廃油について、ドレン弁（８）を操作することにより排出することができ、制御用空気圧縮機（１）を停止することなく気筒部（３）から廃油を排出することができる。 In the invention with the above configuration, since the pipe (7) having the drain valve (8) is attached to the oil reservoir (5) of the cylinder part (3), the waste oil can be obtained simply by opening and closing the drain valve (8). Waste oil can be easily taken out from the drain outlet (6). It is possible to remove the acrylic plate (10) as in the prior art and to work safely without putting a hand near the movable part.

In particular, waste oil accumulated in the oil reservoir (5) during patrol can be discharged by operating the drain valve (8), and the cylinder portion (3) without stopping the control air compressor (1). Waste oil can be discharged from

本発明の制御用空気圧縮機は、各気筒部の油溜り部に、廃油ドレン排出用の排出口を開け、各排出口に、ドレン弁を具備した配管を取り付け、配管の吐出口に油回収器を備えたものである。   The control air compressor of the present invention opens a discharge port for discharging waste oil drain to an oil reservoir of each cylinder, attaches a pipe equipped with a drain valve to each discharge port, and collects oil at a discharge port of the pipe. It is equipped with a vessel.

以下、本発明の好ましい実施の形態を図面を参照して説明する。
図１は実施例１の制御用空気圧縮機を示す正面図である。図２は気筒部の油溜り部の内部を示す斜視図である。
本発明の制御用空気圧縮機１は、いわゆる多気筒空気圧縮機であり、クランク室２に複数の気筒部３を放射形に取り付けたものである。気筒部３の中にはシリンダヘッドが設けられ、クランク室２で回転するクランクによって往復運動するようになっている。図１に示す制御用空気圧縮機１は、４本の気筒部３を備えたものである。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a control air compressor of the first embodiment. FIG. 2 is a perspective view showing the inside of the oil sump portion of the cylinder portion.
The control air compressor 1 according to the present invention is a so-called multi-cylinder air compressor, in which a plurality of cylinder portions 3 are attached to a crank chamber 2 in a radial shape. A cylinder head is provided in the cylinder portion 3 and reciprocates by a crank rotating in the crank chamber 2. A control air compressor 1 shown in FIG. 1 includes four cylinder portions 3.

制御用空気圧縮機１は、シリンダヘッドの往復運動によって、空気を空気吸入器４から吸入して気筒部３内で圧縮し、吐出口から吐出して吐出管を通して空気タンク（図示していない）に導くようになっている。発電所における制御用空気圧縮機１では、例えば圧油タンク補給に用いたり、発電機ブレーキ用に用いられる。   The control air compressor 1 sucks air from the air inhaler 4 by the reciprocating motion of the cylinder head, compresses the air in the cylinder portion 3, discharges it from the discharge port, and passes through the discharge pipe to an air tank (not shown). Is supposed to lead to. In the control air compressor 1 at the power plant, for example, it is used for replenishing a pressure oil tank or for generator brake.

本発明の制御用空気圧縮機１の各気筒部３の油溜り部５に、廃油ドレン排出用の排出口６を開けている。この排出口６には配管７を取り付けている。この配管７は、図示するように油溜り部５から劣化した潤滑油（廃油）を取り出しやすいように、傾斜配置した気筒部３の何れかの角部に接続している。   A discharge port 6 for discharging waste oil drain is opened in the oil reservoir 5 of each cylinder portion 3 of the control air compressor 1 of the present invention. A pipe 7 is attached to the discharge port 6. This pipe 7 is connected to one of the corners of the inclined cylinder section 3 so that the deteriorated lubricating oil (waste oil) can be easily taken out from the oil reservoir section 5 as shown.

配管７の途中にはドレン弁８を設け、これで開閉できるようになっている。この配管７の吐出口９から廃油を取り出し、例えば油回収器１０に貯めることができる。   A drain valve 8 is provided in the middle of the pipe 7 so that it can be opened and closed. Waste oil can be taken out from the discharge port 9 of the pipe 7 and stored in, for example, the oil recovery unit 10.

このように、気筒部３の油溜り部５に、ドレン弁８を具備した配管７を取り付けているので、このドレン弁８を開閉するだけで排出口６から廃油を取り出し、油回収器１０で回収することができる。従来のようにアクリル板１４を外して、可動部の近くに手を入れる作業がなく安全に作業を行うことができる。また、従来のようにアクリル板１４の破損も防止することができる。   In this way, since the pipe 7 having the drain valve 8 is attached to the oil reservoir 5 of the cylinder part 3, the waste oil is taken out from the discharge port 6 just by opening and closing the drain valve 8, and the oil collector 10 It can be recovered. It is possible to safely perform the work without removing the acrylic plate 14 and placing a hand near the movable part as in the prior art. Further, it is possible to prevent the acrylic plate 14 from being damaged as in the prior art.

そこで、パトロール時に油溜り部５に溜まった廃油をドレン弁８を操作することにより排出することができる。即ち、制御用空気圧縮機１を停止することなく気筒部３から廃油を排出することができる。   Therefore, the waste oil accumulated in the oil reservoir 5 during the patrol can be discharged by operating the drain valve 8. That is, the waste oil can be discharged from the cylinder portion 3 without stopping the control air compressor 1.

油溜り部５内において、排出口６の間に補強用リブ１１が形成されているときは、補強用リブ１１に油通過孔１２を開ける。この補強用リブ１１の油通過孔１２に廃油が流れるので、排出口６から廃油が流出しやすくなる。   In the oil reservoir 5, when the reinforcing rib 11 is formed between the discharge ports 6, the oil passage hole 12 is opened in the reinforcing rib 11. Since the waste oil flows through the oil passage hole 12 of the reinforcing rib 11, the waste oil easily flows out from the discharge port 6.

また、油溜り部５には窓部１３を設け、この窓部１３にアクリル板１４を取り付けている。この窓部１３から気筒部３の内部を点検できるようになっている。   The oil reservoir 5 is provided with a window 13, and an acrylic plate 14 is attached to the window 13. The inside of the cylinder part 3 can be inspected from the window part 13.

図３は実施例２の制御用空気圧縮機を示す正面図である。実施例１で説明した部材とその機能は説明を省略する。
本発明の制御用空気圧縮機１は、全部の気筒部３をクランク室２に放射形に、かつ傾斜した状態で取り付けられたものだけではない。例えば図３のように３本の気筒部３を備えた制御用空気圧縮機２１では、１本の気筒部３はクランク室２上に垂直に配置されることがある。 FIG. 3 is a front view showing the control air compressor of the second embodiment. Explanation of the members and functions described in the first embodiment is omitted.
The control air compressor 1 of the present invention is not limited to one in which all the cylinder portions 3 are attached to the crank chamber 2 in a radial and inclined state. For example, as shown in FIG. 3, in the control air compressor 21 having three cylinder portions 3, one cylinder portion 3 may be arranged vertically on the crank chamber 2.

実施例２の制御用空気圧縮機２１は、垂直に配置された気筒部３には、その油溜り部５に排出口６を２箇所開けることが好ましい。各排出口６それぞれに配管７を取り付け、１本に集約した配管７の下流にドレン弁８を取り付ける。これにより、油溜り部５に溜まった廃油を何れかの排出口６から迅速に排出することができる。残りの気筒部３（油溜り部５）は傾斜しているので、それぞれ１本の配管７を取り付けている。   In the control air compressor 21 of the second embodiment, it is preferable to open two outlets 6 in the oil reservoir 5 in the vertically arranged cylinder part 3. A pipe 7 is attached to each of the discharge ports 6, and a drain valve 8 is attached downstream of the pipe 7 gathered into one. Thereby, the waste oil collected in the oil reservoir 5 can be quickly discharged from any of the discharge ports 6. Since the remaining cylinder portions 3 (oil sump portions 5) are inclined, one pipe 7 is attached to each of them.

なお、本発明は、気筒部３に配管７を設けることで、可動部の近くに人の手が近づかないので安全に作業を行え、この空気圧縮機１，２１を停止することなく気筒部３から廃油を排出することができきれば、上述した実施例に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。   In the present invention, the pipe 7 is provided in the cylinder part 3 so that a person's hand does not come close to the movable part, so that the work can be performed safely. The cylinder part 3 can be operated without stopping the air compressors 1 and 21. Of course, as long as the waste oil can be discharged, the invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

本発明の制御用空気圧縮機は、火力発電所、原子力発電所等の復水配管系統に設けられる空気圧縮機以外に、その他の種々のプラントにおける空気圧縮機に利用することができる。   The control air compressor of the present invention can be used for an air compressor in various other plants besides an air compressor provided in a condensate piping system such as a thermal power plant and a nuclear power plant.
