Description

この発明は、例えば、蒸気タービンのような大形回転機械の軸受部などに潤滑油を供給するための潤滑油供給装置に関する。   The present invention relates to a lubricating oil supply device for supplying lubricating oil to a bearing portion of a large rotating machine such as a steam turbine.

電力用・産業用のタービンやタービンで駆動される発電機などの大型の回転機械は、その軸受部に潤滑油が常時供給されることを前提にして構成されることが一般的である。このためこれ等の大型の回転機械には、その軸受部などに潤滑油を循環供給するための潤滑油供給装置が必ず付属されている。そうして、この潤滑油供給装置として、潤滑油を貯留するための油タンク、潤滑油を加圧する油ポンプ、微細な塵埃などを含めた異物を潤滑油から除去する油フィルターおよび潤滑油の温度を所定値にする油冷却器とを備え、これ等の機器の相互間を油配管で接続するものが知られている（例えば、特許文献１参照。)。
特開平９−３２４６０６号公報（第２頁、第４図） A large-sized rotating machine such as an electric power / industrial turbine or a generator driven by the turbine is generally configured on the assumption that lubricating oil is constantly supplied to the bearing portion. For this reason, these large rotating machines are always provided with a lubricating oil supply device for circulating and supplying the lubricating oil to the bearings. Thus, as this lubricating oil supply device, an oil tank for storing the lubricating oil, an oil pump for pressurizing the lubricating oil, an oil filter for removing foreign matter including fine dust from the lubricating oil, and the temperature of the lubricating oil There is known an oil cooler having a predetermined value and connecting these devices with an oil pipe (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 9-324606 (2nd page, FIG. 4)

前述した従来技術による潤滑油供給装置では、油ポンプ，油フィルターあるいは油冷却器などの補機類には、標準的な設計・製造による製品の中から潤滑油供給装置が潤滑油を供給する対象の回転機械（タービンなど）に適合するものが選定されて使用されることが一般的である。このために従来では油ポンプを除いては、これ等の補機類は個別配置が慣例になっている。しかしながら、これ等の補機類の配置には、据付作業や保守作業などのために個別に広い配置スペースが必要になる。また、これ等の補機類および油タンクの配置はプラントによって異なるので、これ等の補機類および油タンクの相互間を接続する潤滑油用の配管の配管作業は現地で行わなければならない。このために、現地作業で行われる配管作業（配管施工・検査作業などが含まれる。）に多くの日時が必要になっている。したがって、この発明の目的は、配置スペースの縮小と現地配管作業の削減が可能な潤滑油供給装置を提供することにある。   In the above-described conventional lubricating oil supply device, the lubricating oil supply device supplies lubricant from auxiliary products such as oil pumps, oil filters or oil coolers from products of standard design and manufacture. In general, a machine that is suitable for a rotating machine (such as a turbine) is selected and used. For this reason, conventionally, except for the oil pump, these auxiliary machines are customarily arranged individually. However, the arrangement of these auxiliary machines requires a wide arrangement space for installation work and maintenance work. In addition, since the arrangement of these auxiliary machines and oil tanks varies depending on the plant, the piping work of the lubricating oil pipes connecting these auxiliary machines and oil tanks must be performed on site. For this reason, many dates and times are required for piping work (including piping construction and inspection work) performed in the field work. Accordingly, an object of the present invention is to provide a lubricating oil supply device capable of reducing the arrangement space and reducing the piping work on site.

この発明では前述の目的は、
１）潤滑油を貯留する油タンクと、前記潤滑油を加圧する油ポンプ，潤滑油中の細かい塵埃を除去する油フィルターおよび潤滑油の温度を所定値にする油冷却器とを備えた油供給装置において、前記油ポンプと、前記油フィルターおよび／または前記油冷却器とを前記油タンク内に設置するようにしたことにより達成される。 In the present invention, the aforementioned object is
1) Oil supply comprising an oil tank that stores lubricating oil, an oil pump that pressurizes the lubricating oil, an oil filter that removes fine dust in the lubricating oil, and an oil cooler that sets the temperature of the lubricating oil to a predetermined value In the apparatus, this is achieved by installing the oil pump, the oil filter and / or the oil cooler in the oil tank.

この発明による潤滑油供給装置では、前記課題を解決するための手段の項で述べた構成とすることで、油タンクに内蔵される油フィルターおよび／または油冷却器に対しては、油タンクに内蔵されることによって、その配置スペースの大幅な縮小や現地据付作業の不要化が可能になる。また、油タンクに内蔵される油フィルターおよび／または油冷却器は、油密容器が不要になることでその製造原価の低減が可能になる。さらに、油タンクに内蔵される油フィルターおよび／または油冷却器に関しては、油タンク，油ポンプ，油フィルターあるいは油冷却器の相互間を接続する接続配管が全く不要になるので、従来それ等の配管施工・検査作業などに要していた現地配管作業の不要化が可能になる、などの多くの効果を得られる。   In the lubricating oil supply apparatus according to the present invention, the oil tank and the oil cooler built in the oil tank can be provided in the oil tank by adopting the configuration described in the section for solving the above problems. By being built in, it is possible to greatly reduce the installation space and eliminate the need for on-site installation work. In addition, the oil filter and / or the oil cooler built in the oil tank can reduce the manufacturing cost by eliminating the need for an oil-tight container. Furthermore, with respect to the oil filter and / or oil cooler built in the oil tank, since connection pipes connecting the oil tank, oil pump, oil filter or oil cooler are not required at all, Many effects can be obtained, such as making it possible to eliminate the need for local piping work required for piping construction and inspection work.

以下この発明を実施するための最良の形態を図面を参照して詳細に説明する。
『実施の形態１』図２は、この発明の実施の形態の一例による潤滑油供給装置を一部記号化して示す説明図である。図２において、１Ａは、潤滑油９を貯留すると共に，油ポンプ３および油冷却器４を内蔵する油タンク２Ａと、油フィルター５Ａなどを備えたこの発明による潤滑油供給装置である。そうして、潤滑油供給装置１Ａが備える補機類などの構成は、前述の特許文献１に述べられている潤滑油装置の場合と基本的に同等である。油ポンプ３は油タンク２Ａに貯留された潤滑油９を加圧してタービンの軸受（不図示）などに向けて送油配管７によって送出するが、潤滑油９中の細かい塵埃を除去するための油フィルター５Ａは、従来技術の場合と同様に送油配管７の途中に接続されている。
潤滑油９から除去した塵埃による油フィルター５Ａの目詰りを検知する目詰りセンサーには、従来技術の場合と同様に差圧スイッチ（不図示）が配設されており、目詰りセンサーの動作時には油フィルター５Ａに対する保守作業が従来技術の場合と同様に実施される。送油配管７に設置された油温検知器９１は、温度検出要素に測温抵抗体，熱電対，サーミスタなどが用いられ、この部位を通流する潤滑油９の温度に対応した内容を持つ信号９１ａを出力する。なお、潤滑油９の通流方向に関して油フィルター５Ａよりも油タンク２Ａ側に接続された絞り８の構造・機能に関しては、前述の特許文献１のの欄の段落番号「０００２」の部分に詳しく説明されているので、その説明を省略する。 The best mode for carrying out the present invention will be described below in detail with reference to the drawings.
[Embodiment 1] FIG. 2 is an explanatory diagram partially showing a lubricating oil supply apparatus according to an embodiment of the present invention. In FIG. 2, 1A is a lubricating oil supply apparatus according to the present invention, which stores lubricating oil 9, and includes an oil tank 2A containing an oil pump 3 and an oil cooler 4, an oil filter 5A, and the like. Thus, the configurations of the auxiliary machines and the like included in the lubricating oil supply device 1A are basically the same as those of the lubricating oil device described in Patent Document 1 described above. The oil pump 3 pressurizes the lubricating oil 9 stored in the oil tank 2 </ b> A and feeds it toward the turbine bearing (not shown) by the oil feeding pipe 7, but for removing fine dust in the lubricating oil 9. The oil filter 5A is connected in the middle of the oil feed pipe 7 as in the case of the prior art.
The clogging sensor that detects clogging of the oil filter 5A due to dust removed from the lubricating oil 9 is provided with a differential pressure switch (not shown) as in the case of the prior art, and during operation of the clogging sensor. Maintenance work for the oil filter 5A is performed in the same manner as in the prior art. The oil temperature detector 91 installed in the oil feeding pipe 7 uses a resistance temperature detector, a thermocouple, a thermistor or the like as a temperature detection element, and has contents corresponding to the temperature of the lubricating oil 9 flowing through this portion. The signal 91a is output. The structure and function of the throttle 8 connected to the oil tank 2A side of the oil filter 5A with respect to the flow direction of the lubricating oil 9 is described in detail in the paragraph “0002” in the section of Patent Document 1 described above. Since it is described, its description is omitted.

油冷却器４は、この事例の場合には、潤滑油９をタービンの軸受などから油タンク２Ａに戻すための戻り油配管７１が油タンク２Ａに接続される部位に近接されて油タンク２Ａ内に配設される。この油冷却器４は多数の冷却管が用いられた冷却体４１を有するが、油冷却器４には冷却体４１の冷却管の内部に通流させる冷却水４９を供給する配管４８と、配管４８に介装されて冷却水４９の流量を調節する流量調整弁４７が接続される。冷却水４９の流量調整は、油温検知器９１の信号９１ａに応じて流量調整弁４７の弁開度が調節されることで行われるが、この油冷却器４への冷却水４９の供給構造，冷却水４９の流量調整方法や冷却体４１の構造は、従来技術の場合と同等である。
油冷却器４は油タンク２Ａに内蔵されることを前提とするために、従来技術の潤滑油供給装置に用いられている油冷却器とは異なって油密容器が設けられていない。油タンク２Ａには油冷却器４が内蔵される部位にバッフル体２１が備えられている。このバッフル体２１は、冷却体４１の冷却管の外面に潤滑油９を図２に模式的に示したように蛇行させて通流させることで、潤滑油９から冷却管への熱伝達を良好にさせて、油冷却器４の冷却効率を高めるようにしている。また、このバッフル体２１は戻り油配管７１から油タンク２Ａに戻る潤滑油９の全量を油冷却器４に通流させるようにする案内体の機能も備えている。 In this case, the oil cooler 4 is located in the oil tank 2A in the vicinity of a portion where a return oil pipe 71 for returning the lubricating oil 9 from the turbine bearing or the like to the oil tank 2A is connected to the oil tank 2A. It is arranged. The oil cooler 4 includes a cooling body 41 in which a large number of cooling pipes are used. The oil cooler 4 includes a pipe 48 for supplying cooling water 49 to be passed through the cooling pipe of the cooling body 41, and a pipe. A flow rate adjusting valve 47 is connected to 48 and adjusts the flow rate of the cooling water 49. The flow rate of the cooling water 49 is adjusted by adjusting the valve opening degree of the flow rate adjusting valve 47 in accordance with the signal 91a of the oil temperature detector 91. A structure for supplying the cooling water 49 to the oil cooler 4 is as follows. The flow rate adjusting method of the cooling water 49 and the structure of the cooling body 41 are the same as those of the conventional technique.
Since the oil cooler 4 is assumed to be built in the oil tank 2A, an oil-tight container is not provided unlike the oil cooler used in the conventional lubricating oil supply device. The oil tank 2A is provided with a baffle body 21 at a site where the oil cooler 4 is built. The baffle body 21 allows the lubricating oil 9 to meander and flow through the outer surface of the cooling pipe of the cooling body 41 as schematically shown in FIG. 2 so that heat transfer from the lubricating oil 9 to the cooling pipe is good. Thus, the cooling efficiency of the oil cooler 4 is increased. The baffle body 21 also has a guide body function that allows the entire amount of the lubricating oil 9 returning from the return oil pipe 71 to the oil tank 2 </ b> A to flow through the oil cooler 4.

図２に示すこの発明の実施の形態の一例による潤滑油供給装置１Ａでは前述の構成としたので、従来技術の場合と対比すると、油ポンプ３に加えて油冷却器４が油タンク２Ａに内蔵されたことになる。このことによって、油タンク２Ａの外形の若干の増大があるものの、油冷却器４に対する個別配置スペースが不要になると共に、油冷却器４の現地据付作業が不要になる。また、油冷却器４は油密容器が不要になることで製造原価が低減される。さらに、油冷却器と油タンクとの間を接続する接続配管が不要になるので、従来ではそれ等の配管施工・検査作業などに要していた現地配管作業を不要にできる。
『実施の形態２』図３はこの発明の実施の形態の異なる例による潤滑油供給装置を一部記号化して示す説明図である。なお、以下の説明においては、図２に示したこの発明による潤滑油供給装置１Ａと同一部分には同じ符号を付しその説明を省略する。図３に示す潤滑油供給装置１Ｂは、図２に示したこの発明による潤滑油供給装置１Ａに対して、油冷却器に替えて油フィルターを油タンクに内蔵するようにした潤滑油供給装置である。図３において、１Ｂは、潤滑油９を貯留すると共に，油ポンプ３および油フィルター５を内蔵する油タンク２Ｂと、油冷却器４Ｂなどを備えたこの発明による潤滑油供給装置である。 Since the lubricating oil supply apparatus 1A according to the embodiment of the present invention shown in FIG. 2 has the above-described configuration, the oil cooler 4 is built in the oil tank 2A in addition to the oil pump 3 as compared with the case of the prior art. It will be done. As a result, although there is a slight increase in the outer shape of the oil tank 2A, an individual arrangement space for the oil cooler 4 is not required, and an on-site installation operation of the oil cooler 4 is not required. Further, the oil cooler 4 does not require an oil-tight container, thereby reducing the manufacturing cost. Furthermore, since no connection piping for connecting between the oil cooler and the oil tank is required, it is possible to eliminate the local piping work conventionally required for such pipe construction and inspection work.
[Embodiment 2] FIG. 3 is an explanatory view partially showing a lubricating oil supply apparatus according to a different example of the embodiment of the present invention. In the following description, the same parts as those in the lubricating oil supply apparatus 1A according to the present invention shown in FIG. The lubricating oil supply device 1B shown in FIG. 3 is a lubricating oil supply device in which an oil filter is built in an oil tank in place of the oil cooler in contrast to the lubricating oil supply device 1A according to the present invention shown in FIG. is there. In FIG. 3, reference numeral 1B denotes a lubricating oil supply apparatus according to the present invention, which stores the lubricating oil 9, and includes an oil tank 2B incorporating the oil pump 3 and the oil filter 5, an oil cooler 4B, and the like.

そうして、潤滑油供給装置１Ｂが備える補機類などの構成は、前述の特許文献１に述べられている潤滑油装置の場合と基本的には同等である。従来技術の潤滑油供給装置に用いられているものと同一の油冷却器４Ｂは、従来技術の場合と同様に送油配管７の途中に接続されている。なお、油冷却器４Ｂは前記『実施の形態１』で説明した油冷却器４の場合と同様に水冷式であり、油温検知器９１が出力する信号（不図示）に応じて流量調整弁（不図示）の弁開度が調節されることで行われるが、この部分は潤滑油供給装置１Ａの場合と同一のため重複を避けてその説明は省略する。
油フィルター５は、この事例の場合には、戻り油配管７１が油タンク２Ｂに接続される部位に近接されて油タンク２Ｂ内に配設される。油フィルター５が内蔵される部位の油タンク２Ｂには油フィルター装着体２２が備えられ、この油フィルター装着体２２は、戻り油配管７１から油タンク２Ｂに戻る潤滑油９の全量を油フィルター５に通流させるようにする案内体の機能も備えている。この油フィルター５には、潤滑油９中の塵埃の除去を行うフィルターエレメントとして従来技術の場合と同等のものが用いられている。 Thus, the configuration of the auxiliary machines and the like provided in the lubricating oil supply device 1B is basically the same as that of the lubricating oil device described in Patent Document 1 described above. The same oil cooler 4B as that used in the conventional lubricating oil supply device is connected in the middle of the oil feeding pipe 7 as in the case of the prior art. The oil cooler 4B is a water-cooled type as in the case of the oil cooler 4 described in the “Embodiment 1”, and a flow rate adjusting valve according to a signal (not shown) output from the oil temperature detector 91. This is done by adjusting the valve opening degree (not shown), but this part is the same as in the case of the lubricating oil supply device 1A, and therefore its description is omitted to avoid duplication.
In this case, the oil filter 5 is disposed in the oil tank 2B in proximity to a portion where the return oil pipe 71 is connected to the oil tank 2B. An oil filter mounting body 22 is provided in the oil tank 2B where the oil filter 5 is built, and the oil filter mounting body 22 removes the entire amount of the lubricating oil 9 returning from the return oil pipe 71 to the oil tank 2B. It also has the function of a guide body that allows it to flow through. In this oil filter 5, a filter element equivalent to that in the prior art is used as a filter element for removing dust in the lubricating oil 9.

油フィルター５は油タンク２Ｂに内蔵されることを前提とするために、従来技術の潤滑油供給装置に用いられている油フィルターとは異なって油密容器が設けられていない。油タンク２Ｂに接続される部位の戻り油配管７１には、潤滑油９から除去した塵埃による油フィルター５の目詰りを検知するためのレベルスイッチ９９が配設されている。レベルスイッチ９９は油フィルター５の目詰りの進行に伴う潤滑油９の油面状態を検知し、この油面の上昇が設定値を越えると目詰りセンサーであるレベルスイッチ９９が動作する。目詰りセンサーが動作した場合の油フィルター５に対する保守動作の内容は、従来技術の場合と同様である。
図３に示すこの発明の実施の形態の異なる例による潤滑油供給装置１Ｂでは前述の構成としたので、従来技術の場合と対比すると、油ポンプ３に加えて油フィルター５が油タンク２Ｂに内蔵されたことになる。このことによって、油タンク２Ｂの外形の若干の増大があるものの、油フィルター５に対する個別配置スペースが不要になると共に、油フィルター５の現地据付作業が不要になる。また、油フィルター５は油密容器が不要になることで製造原価が低減される。さらに、油フィルターと絞り８との間を接続する接続配管などが不要になるので、従来ではそれ等の配管施工・検査作業などに要していた現地配管作業を不要にできる。
『実施の形態３』図１はこの発明の実施の形態のさらに異なる例による潤滑油供給装置を一部記号化して示す説明図である。なお、以下の説明においては、図３に示したこの発明による潤滑油供給装置１Ｂと同一部分には同じ符号を付しその説明を省略する。図１に示す潤滑油供給装置１は、図２，図３に示したこの発明による潤滑油供給装置１Ａ，１Ｂに対して、油冷却器と油フィルターを共に油タンクに内蔵するようにした潤滑油供給装置である。図１において、１は、潤滑油９を貯留すると共に、油ポンプ３，油冷却器４および油フィルター５を内蔵する油タンク２などを備えたこの発明による潤滑油供給装置である。 Since it is assumed that the oil filter 5 is built in the oil tank 2B, an oil-tight container is not provided unlike the oil filter used in the conventional lubricating oil supply device. A level switch 99 for detecting clogging of the oil filter 5 due to dust removed from the lubricating oil 9 is disposed in the return oil piping 71 connected to the oil tank 2B. The level switch 99 detects the oil level of the lubricating oil 9 as the clogging of the oil filter 5 progresses. When the rise in the oil level exceeds a set value, the level switch 99 serving as a clogging sensor operates. The content of the maintenance operation for the oil filter 5 when the clogging sensor is activated is the same as in the case of the prior art.
Since the lubricating oil supply device 1B according to the different embodiment of the present invention shown in FIG. 3 has the above-described configuration, the oil filter 5 is built in the oil tank 2B in addition to the oil pump 3 as compared with the case of the prior art. It will be done. As a result, although there is a slight increase in the outer shape of the oil tank 2B, an individual arrangement space for the oil filter 5 is not required, and an on-site installation operation of the oil filter 5 is not required. Moreover, the manufacturing cost is reduced because the oil filter 5 does not require an oil-tight container. Furthermore, since no connection piping for connecting the oil filter and the throttle 8 is required, it is possible to eliminate the local piping work conventionally required for such pipe construction / inspection work.
[Embodiment 3] FIG. 1 is an explanatory view partially showing a lubricating oil supply apparatus according to still another example of an embodiment of the present invention. In the following description, the same parts as those in the lubricating oil supply apparatus 1B according to the present invention shown in FIG. The lubrication oil supply device 1 shown in FIG. 1 is a lubrication system in which an oil cooler and an oil filter are both built in an oil tank, compared to the lubrication oil supply devices 1A and 1B according to the present invention shown in FIGS. Oil supply device. In FIG. 1, reference numeral 1 denotes a lubricating oil supply device according to the present invention that stores lubricating oil 9 and includes an oil pump 3, an oil cooler 4, and an oil tank 2 containing an oil filter 5.

そうして、潤滑油供給装置１が備える補機類などの構成は、前述の特許文献１に述べられている潤滑油装置の場合と基本的には同等である。この事例の場合には、油フィルター５は図３に示したこの発明による潤滑油供給装置１Ｂの場合と同一部位の油タンク２内に配設され、また、油冷却器４は油フィルター５を通過した後の潤滑油９を冷却するべく油タンク２内に配設されている。油タンク２には油冷却器４が内蔵される部位にバッフル体２３が備えられている。このバッフル体２３は、図２に示したこの発明による潤滑油供給装置１Ａの場合と同様に、冷却体４１の冷却管の外面に潤滑油９を図１に模式的に示したように蛇行させて通流させると共に、戻り油配管７１から油タンク２に戻る潤滑油９の全量を油冷却器４に通流させるようにする案内体の機能を備えている。
図１に示すこの発明の実施の形態のさらに異なる例による潤滑油供給装置１では前述の構成としたので、従来技術の場合と対比すると、油ポンプ３に加えて油冷却器４および油フィルター５が油タンク２に内蔵されたことになる。このことによって、油タンク２の外形の若干の増大があるものの、油冷却器４および油フィルター５に対する個別配置スペースが不要になると共に、油冷却器４および油フィルター５の現地据付作業が不要になる。また、油冷却器４および油フィルター５は油密容器が不要になることで製造原価が低減される。さらに、油冷却器と油タンクとの間を接続する接続配管および油フィルターと絞り８との間を接続する接続配管などが不要になるので、従来ではそれ等の配管施工・検査作業などに要していた現地配管作業を不要にできる。 Thus, the configuration of the auxiliary machines and the like included in the lubricating oil supply device 1 is basically the same as that of the lubricating oil device described in Patent Document 1 described above. In this case, the oil filter 5 is disposed in the oil tank 2 at the same location as the case of the lubricating oil supply device 1B according to the present invention shown in FIG. 3, and the oil cooler 4 It is arranged in the oil tank 2 to cool the lubricating oil 9 after passing through. The oil tank 2 is provided with a baffle body 23 at a site where the oil cooler 4 is incorporated. As in the case of the lubricating oil supply apparatus 1A according to the present invention shown in FIG. 2, the baffle body 23 causes the lubricating oil 9 to meander on the outer surface of the cooling pipe of the cooling body 41 as schematically shown in FIG. And a function of a guide body that allows the entire amount of the lubricating oil 9 returning to the oil tank 2 from the return oil pipe 71 to flow to the oil cooler 4.
Since the lubricating oil supply apparatus 1 according to a further different example of the embodiment of the present invention shown in FIG. 1 has the above-described configuration, the oil cooler 4 and the oil filter 5 in addition to the oil pump 3 are compared with the case of the prior art. Is built in the oil tank 2. As a result, although there is a slight increase in the outer shape of the oil tank 2, an individual arrangement space for the oil cooler 4 and the oil filter 5 is not required, and on-site installation work of the oil cooler 4 and the oil filter 5 is not required. Become. Further, the oil cooler 4 and the oil filter 5 do not require an oil-tight container, thereby reducing the manufacturing cost. In addition, connection piping connecting between the oil cooler and the oil tank and connection piping connecting between the oil filter and the throttle 8 are unnecessary, and conventionally required for such piping construction and inspection work. This eliminates the need for local piping work.

なお、前記した配置スペースの縮小と現地配管作業の削減が可能な潤滑油供給装置を提供するとのこの発明の目的からは、『実施の形態１』〜『実施の形態３』の中ではこの『実施の形態３』で示した潤滑油供給装置１が最も好ましいことになる。しかし、潤滑油供給装置の据付け場所の制約条件や，据付け場所への運搬上の制約などを考慮した場合に、潤滑油供給装置１による構成を持つ潤滑油供給装置を適用できない場合が考えられる。その場合には油タンクに内蔵する機器の範囲を限定した、図２，図３に示したこの発明による潤滑油供給装置１Ａ，１Ｂによる構成を持つ潤滑油供給装置が適用されることになる。   From the object of the present invention to provide a lubricating oil supply device capable of reducing the above-described arrangement space and reducing on-site piping work, the “embodiment 1” to “embodiment 3” The lubricating oil supply apparatus 1 shown in “Embodiment 3” is most preferable. However, in consideration of restrictions on the installation location of the lubricating oil supply device and restrictions on transportation to the installation location, there may be cases where the lubricating oil supply device having the configuration of the lubricating oil supply device 1 cannot be applied. In that case, the lubricating oil supply device having the configuration of the lubricating oil supply devices 1A and 1B according to the present invention shown in FIGS.
