Description
本発明の目的は、特に０℃未満での潤滑油組成物のエネルギー消費量を改善することで
ある。
本発明の他の目的は、油圧操作式持上げ装置の持上げ時間を短縮することである。
The object of the present invention is to improve the energy consumption of a lubricating oil composition, especially below 0 ° C.
Another object of the present invention is to shorten the lifting time of a hydraulically operated lifting device.
本発明によれば、特に０℃未満の低温では、ＶＩが１９０を超える流体を用いると、エ
ネルギー消費量が減少することが意外にも見出された。この結果、例えば油圧操作式吊上
げ装置を用いて持上げ中、エネルギー消費量が少なくて済む。
In accordance with the present invention, it has been surprisingly found that energy consumption is reduced, especially when using fluids with a VI greater than 190, especially at low temperatures below 0 ° C. As a result, less energy is consumed, for example, during lifting using a hydraulically operated lifting device.
流動点下剤の例は、ポリメタクリレート系重合体である。
本発明の潤滑油組成物は、１種以上の基油、１種以上のＶＩ向上剤、及び１種以上の別の添加剤をブレンドすることにより、都合よく製造できる。
別の局面では本発明は、油圧操作式持上げ装置での重量物の持上げ時間を短縮するために前記潤滑油組成物を使用する方法を提供する。
An example of a pour point laxative is a polymethacrylate polymer.
The lubricating oil composition of the present invention can be conveniently prepared by blending one or more base oils, one or more VI improvers, and one or more other additives.
In another aspect, the present invention provides a method of using the lubricating oil composition to reduce the lifting time of heavy objects in a hydraulically operated lifting device.
油圧操作式持上げ装置の非限定的例は、フォークリフトトラック、ごみ（ｇａｒｂａｇｅ）トラック、サクランボ摘み機、露天掘り鉱山（ｏｐｅｎ ｃａｓｔ ｍｉｎｉｎｇ）設備等である。
また本発明は、前述のような潤滑油組成物を使用することにより、油圧システムにおけるエネルギー消費量を改善する方法を提供する。
Non-limiting examples of hydraulically operated lifting devices are forklift trucks, garbage trucks, cherry pickers, open cast mining equipment and the like.
The present invention also provides a method for improving energy consumption in a hydraulic system by using a lubricating oil composition as described above.
更に本発明は前述のような潤滑油組成物を使用することにより、油圧操作式持上げ装置
における重量物の持上げ時間を短縮する方法を提供する。
本発明を以下の実施例を参照して本発明を説明するが、これらの実施例はいかなる方法
でも本発明範囲の限定を意図するものではない。
Furthermore, the present invention provides a method for shortening the lifting time of a heavy load in a hydraulically operated lifting device by using the lubricating oil composition as described above.
The invention will now be described with reference to the following examples, which are not intended to limit the scope of the invention in any way.
エネルギー消費量試験／平均持上げ時間試験
表１及び表２に記載の配合物をエネルギー消費量について試験した。
この目的のため、表１及び表２の配合物は、１．２５トンの持上げ能力を有するＪｕｎｇｈｅｉｎｒｉｃｈフォークリフトトラック、ＥＦＧ−ＤＨ型１２，５ ３３０の電力式油圧システムに使用した。
Energy Consumption Test / Average Lift Time Test The formulations described in Tables 1 and 2 were tested for energy consumption.
For this purpose, the formulations in Tables 1 and 2 were used in a Jungheinrich forklift truck, EFG-DH type 12,5330 electric hydraulic system with a lifting capacity of 1.25 tons.
配合物の温度を制御ユニット、溜め及び油圧シリンダー（“持上げフレーム”）で連続
的に測定した。油圧を制御ユニット、ポンプ出口及び持上げフレームで測定した。
The temperature of the formulation was measured continuously with a control unit, reservoir and hydraulic cylinder (" lifting frame"). The oil pressure was measured at the control unit, pump outlet and lifting frame.
結果
下記表３は、各配合物について容器を１０回持ち上げた後の累積電気エネルギー消費量（Ｗｈ）を示す。
表４は、参照基本線として比較例１（ＶＩ＝９５）との差（％）として表したデータを
示す。
更に表５は、１０サイクルでの平均持上げ時間（秒）を示す。
Results Table 3 below shows the cumulative electrical energy consumption (Wh) after lifting the container 10 times for each formulation.
Table 4 shows data represented as a difference (%) from Comparative Example 1 (VI = 95) as a reference basic line.
Further, Table 5 shows the average lifting time (seconds) in 10 cycles.
