產品介紹∣油封幫浦

持有成本低，具備永續效能

創新的 Leybold SOGEVAC B 單段式油封旋轉葉片幫浦是現代工業應用的理想選擇，具備低噪音等級、高抽氣速度和高可靠性等特色。SOGEVAC B 幫浦的抽氣能力範圍在 50 Hz 時為 10 至 750 m3/h，極限壓力 ≤ 8 × 10-2 mbar。

轉子具有三個槽而葉片在其中滑動，以偏心位置安裝在幫浦氣缸 (定子) 中。葉片將內部空間分成三個腔室。這些腔室的體積隨轉子的旋轉而變化。吸入進氣室的氣體被壓縮，然後通過排氣閥排出。進油腔內注入的油確保了幫浦腔室的氣密性、潤滑性和冷卻性。油氣被壓縮氣體拖走並在進入油箱時，在重力作用下粗略分離；然後在排氣過濾器中進行更精細的分離，油損耗低於 1 ppm 的工業的基準。

SOGEVAC BI 和 DI 幫浦在進氣法蘭配備了防返油閥，避免油在幫浦停止時回流到進氣管內，並配有氣鎮閥，用於抽除凝結性蒸氣，並提供必要的油。

產品優勢

輕巧設計，低碳足跡
無馬達聯軸器可達 SV65 B
幫浦油排放量極低
最先進的密封技術
在任何工作條件下都有非常低的噪音等級
可客製化組態
簡化的維護與保養

抽除非凝結性氣體

SOGEVAC B 幫浦在不使用氣鎮的情況下運行時，在具有不凝性氣體的應用中表現出高可靠性。如果要抽除的氣體的成分未知並且不能排除幫浦中的冷凝，則幫浦應在氣鎮開啟下運行。

凝結氣體和蒸氣的抽除

在氣鎮打開並處於工作溫度時，SOGEVAC B 油封旋片幫浦可以抽除純水蒸氣，最高可達技術數據中標示的值。

若是 65 m3/h 以上的幫浦，則會供應必要的幫浦油。

Low cost of ownership with sustainable performance
The innovative Leybold SOGEVAC B single-stage oil sealed rotary vane pumps are ideal for modern industrial applications distinguished by low noise levels, high pumping speeds and high reliability. SOGEVAC B pumps have a pumping capacity range from 10 to 750 m3/h @ 50 Hz with an ultimate pressure of ≤ 8 X 10-2 mbar.

The rotor, having three slots in which the vanes slide, is eccentrically installed in a pump cylinder (stator). The vanes separate the interior space into three chambers. The volume of these chambers varies with the rotation of the rotor. The gas sucked into the inlet chamber is compressed and then pushed out through the exhaust valve. The oil injected in the inlet chamber guarantees the air-tightness, lubrication and cooling of the pump. It is dragged off by the compressed gases and roughly separated by gravity when entering in the oil sump. A fine separation is then operated in the exhaust filter, with an oil loss of below 1 ppm which is a benchmark in the industry.

SOGEVAC B pumps are equipped with an anti-suck back valve at the inlet flange avoids oil coming back into the inlet line when the pump is stopped and a...

Pumping of non-condensable gases

SOGEVAC B pumps show high reliability in applications with non-condensable gases when operated without gas ballast. If the composition of the gases to be pumped is not known and if condensation in the pump cannot be ruled out, the pump is operated with open gas ballast.

Pumping of condensable gases and vapors

With the gas ballast open and at operating temperature, the SOGEVAC B oil sealed rotary vane pumps can pump pure water vapor up to the values indicated in the Technical Data.

The necessary oil is supplied in the pump for those bigger than 65 m³/h.
