應用：
Application:

▲往復式真空泵排氣量較大，多用于真空浸漬、鋼水真空處理、真空蒸餾、真空蒸發、真空濃縮、真空結晶、真空干燥、真空過濾及混凝土的真空作業等方面抽出氣體。
Reciprocating pump has large volume of extraction, is mainly used for gas extraction in the aspect of vacuum impregnation, molten steel vacuum process, vacuum distillation, vacuum evaporation, vacuum concentration, vacuum crystallization, vacuum drying, vacuum filtering and vacuum work of concrete.

▲往復式真空泵對于抽除腐蝕性的氣體或含有顆粒狀灰塵的氣體是不適用的。被抽氣體中如果含有灰塵，在泵的進口處必須加裝過濾器。
Reciprocating pump is not suitable for the extraction of corrosive gas or the gas with graininess dusts.Filter must be installed at the inlet of the pump if there exists dusts in the extracted gas.
