【解決手段】ロータリーポンプ１に付いている覗き窓を大きくまたは細長くもしくは分割して低部の水の量を確認できるような覗き窓３ｂとする。水抜き作業に当たっては、上記覗き窓３ｂから水の量を確認しながら水抜き作業を行うことにより、無駄に潤滑油を廃出することをなくすことができる。
【選択図】図２Provided is a rotary pump which can efficiently perform the work of draining water accumulated at the bottom by providing a viewing window for confirming the amount of water accumulated in the rotary pump.
The viewing window attached to the rotary pump is made large, elongated, or divided into a viewing window that can confirm the amount of water in the lower part. In the draining operation, the draining operation is performed while confirming the amount of water from the viewing window 3b, so that it is possible to eliminate wasteful use of the lubricating oil.

Description
本考案は、真空ポンプの一種、ロータリーポンプ（油回転ポンプ）に関するものである。 The present invention relates to a kind of vacuum pump, a rotary pump (oil rotary pump).
本考案は、ロータリーポンプに関するものである。 The present invention relates to a rotary pump.
ロータリーポンプが、容器内の排気を行う時、容器に含まれている水蒸気も排気する。水蒸気は、ロータリーポンプ内で加圧され水となりロータリーポンプ内にとどまる場合もある。このロータリーポンプ内に取り込まれた水分はロータリーポンプの排気性能を低下させるので定期的に抜き取る必要がある。ロータリーポンプに取り込まれた水分は、ポンプを止めると比重の差で水と油に分離する。水は下部に溜まるので、ロータリーポンプ底の栓を開いて水を抜く。この時不便なのは水がどの程度ロータリーポンプ内に入っているか見る事が出来ない事である。 When the rotary pump exhausts the container, the water vapor contained in the container is also exhausted. In some cases, the water vapor is pressurized in the rotary pump to become water and stay in the rotary pump. Since moisture taken into the rotary pump deteriorates the exhaust performance of the rotary pump, it is necessary to extract it periodically. Moisture taken into the rotary pump is separated into water and oil by the difference in specific gravity when the pump is stopped. Since water accumulates in the lower part, open the plug at the bottom of the rotary pump and drain the water. What is inconvenient at this time is that you cannot see how much water is in the rotary pump.
上記問題は、ロータリーポンプのオイル確認用覗き窓を大きくするか縦長にするかまたは、ロータリーポンプの底部に新た水確認用窓を設けることによってロータリーポンプの底部で水分量を確認しながら水抜き作業が出来る事によって解決される。 The above problem is that drainage work is performed while checking the amount of water at the bottom of the rotary pump by increasing the length of the rotary pump oil check window or making it vertically long or providing a new water check window at the bottom of the rotary pump. It is solved by being able to.
本考案の覗き窓を有するロータリーポンプでは、オイルに取り込まれた水がどのくらいあるかすぐわかるので、水抜きが簡単に、効率よくできる。従ってロータリーポンプの排気性能低下を阻止できると同時にポンプ内部の水による腐食防止と油の劣化防止という効果が期待できる。 With the rotary pump having a viewing window according to the present invention, it is possible to immediately know how much water has been taken into the oil, so that draining can be performed easily and efficiently. Therefore, it is possible to prevent the deterioration of the exhaust performance of the rotary pump, and at the same time, the effect of preventing corrosion due to water inside the pump and preventing deterioration of oil.
ロータリーポンプは、ローターが回転して空気を圧縮して排気する。その気密性と潤滑性を担っているのが油である。この油は、排出される空気の量によっては、空気排出時大気に排出される。従って、油の量は常に確認する必要がある。また、空気圧縮時に水蒸気が液化して水になり、ロータリーポンプ内にとどまる場合がある。この水分は、ロータリーポンプ内の腐食の原因であり、排気性能を阻害するので取り除く必要がある。水の取り除き作業は、現場任せである。ロータリーポンプは停止時には、図1及び図２のように潤滑油が溜まっている。潤滑油の中に水が混入している場合は図の３a（油分）と３ｂ（水）に分離し、水は、底に溜まる。そこで、栓を外して水を抜き油が出てきたらあわてて栓を閉めるという作業を行い、現場は水をぬいている。水抜き時には、少量の油漏れを起こしている。なぜなら、水の量を確認する事が出来ないからである。本考案は、油と水の量を同時に確認できる覗き窓をロータリーポンプに付けることである。本考案の覗き窓により、油漏れを止してロータリーポンプ内の水を抜くことができる。潤滑油の中の水を適時に抜くことでロータリーポンプ性能を維持でき、また潤滑油の節約にもつながる。 In the rotary pump, the rotor rotates and compresses and exhausts air. Oil is responsible for its airtightness and lubricity. This oil is discharged to the atmosphere when discharging air depending on the amount of air discharged. Therefore, it is always necessary to check the amount of oil. In addition, when air is compressed, water vapor may be liquefied to become water and stay in the rotary pump. This moisture is a cause of corrosion in the rotary pump and hinders exhaust performance, so it must be removed. The work of removing water is left to the field. When the rotary pump is stopped, lubricating oil is accumulated as shown in FIGS. When water is mixed in the lubricating oil, it is separated into 3a (oil) and 3b (water) in the figure, and the water accumulates at the bottom. Therefore, the work is done by removing the stopper, draining the water, and closing the stopper when the oil comes out. When draining, a small amount of oil leaks. This is because the amount of water cannot be confirmed. The present invention is to attach a viewing window to the rotary pump that can simultaneously check the amount of oil and water. With the viewing window of the present invention, oil leakage can be stopped and water in the rotary pump can be drained. By removing the water in the lubricating oil in a timely manner, the rotary pump performance can be maintained and the lubricating oil can be saved.
本考案の実施例を示す。本考案の実施例は、図２である。ロータリーポンプに油が貯まるポンプ内部の底まで見える覗き窓を取り付けたものである。液が見える部分の寸法は、幅が３cmで高さが１２cmであった。図１の従来の覗き窓は、直径が約7.5cmの覗き窓であった。図２の３bに示された水を覗き窓から見る事が出来るので、水を容易に排出でた。
本考案は、以上のような単純なものであり、様々な応用が可能である。例えば、縦長の形状の代わりに複数の円形、多角形にすることもできる。
The Example of this invention is shown. An embodiment of the present invention is shown in FIG. This is a rotary pump with a viewing window that can see the bottom of the pump where oil is stored. The dimensions of the portion where the liquid was visible were 3 cm in width and 12 cm in height. The conventional viewing window in FIG. 1 was a viewing window having a diameter of about 7.5 cm. Since the water shown in 3b of FIG. 2 can be seen from the viewing window, the water was easily discharged.
The present invention is simple as described above, and various applications are possible. For example, a plurality of circles and polygons can be used instead of the vertically long shape.
