VPS®C系列干式螺桿真空泵

(變螺距干式螺桿真空泵)

優(yōu)異的抗腐蝕性氣體及其所夾帶液體的處理能力,，真空度可達(dá)10-3托,。

Excellent corrosive gas and entrain liquid handling capabilities and realizes 10-3 torr vacuum degree

VPS的C系列干式真空泵包含所有P系列的傳統(tǒng)優(yōu)勢(shì)

（極限真空度高,、防腐蝕及冷氣效果等）

VPS dry vacuum pump includes the standard advantage of the P Series(Single

Pitch) model ad following details

(Low utimate pressure, corrosion resistance, cooling effect, etc.)

極限真空度高
Low Ultimate Pressure

干式螺桿真空泵能在大氣壓至極限壓力的全范圍內(nèi)持續(xù)運(yùn)行,。單泵運(yùn)行極限真空度可以達(dá)到1Pa，并且效率極高,。

The dry vacuum pumps can operate continuously in all the ranges of pressure from atmosphere to the ultimate pressure, and it can reach at 0.0075Torr(1Pa) by itself and has a high efficiency.

防腐蝕設(shè)計(jì) Corrosion Resistance Design

- 經(jīng)過(guò)特殊涂層（PTFE,、PFA,、Ni,、NIFA等）處理可以用于輸送有毒,、有腐蝕性和可冷凝的氣體。

Suitable for pumping Toxic, Corrosive and condensable gas by special coating(PTFE, PFA, Ni, NIFA).

-通過(guò)氣鎮(zhèn)降低蒸汽的壓力來(lái)防止腐蝕性氣體冷凝,。

Prevents condensation of corrosive gas through lowering vapor pressure by the gas ballast.

-冷卻效果好

Cooling Effect is good.

- 無(wú)需冷卻氣體

No Cooling Gas necessary.

- 獨(dú)特的夾套水冷結(jié)構(gòu)

Unique hydrodynamic spiral jacket structure.

- 出口溫度降至符合或接近T4要求

Reduce discharge temperature greatly & close to T4 requirement.

能耗         Power Consumption
-變螺距結(jié)構(gòu)設(shè)計(jì)      Variable pitch screw design.

- 能耗降低30%以上        Power consumption reduced 30%
